From Classroom to Social Action: The Effectiveness of Integrating Project Citizen and Project-Based Learning in Enhancing Students’ Civic Engagement
From Classroom to Social Action: The Effectiveness of Integrating Project Citizen and Project-Based Learning in Enhancing Students' Civic Engagement. This study aims to analyze the effectiveness of integrating Project Citizen and Project-Based Learning (PjBL) in enhancing students' civic engagement, which includes civic knowledge, civic skills, and civic disposition. The novelty of this research lies in the quantitative examination of the effectiveness of integrating both approaches using a quasi-experimental design with a control group, which differs from previous studies that tend to examine only one approach or employ action research designs without comparison groups. Furthermore, this study measures the impact of integration on civic engagement comprehensively and simultaneously across all three dimensions (civic knowledge, civic skills, and civic disposition), rather than focusing solely on one or two specific aspects such as critical thinking or attitudes alone. A quantitative approach with a quasi-experimental design using a nonequivalent control group design was employed, involving 60 students from the Civic Education Study Program at FKIP Universitas Lampung, divided into experimental and control groups. Data were collected through questionnaires, observations, and documentation, and analyzed using validity and reliability tests, normality and homogeneity tests, t-tests, and Normalized Gain (N-Gain) calculations. The results revealed a significant difference between the experimental and control groups, with a significance value of 0.018 (p < 0.05). The experimental group achieved a higher mean score (78.43) than the control group (74.20), with an N-Gain of 0.57 (medium to high category). The integration of these two approaches fosters participatory, contextual, and applicable learning, effectively bridging the gap between classroom learning and real social action. These findings provide an innovative contribution to civic education practices by positioning students as social change agents and offering a strategic learning model relevant to the challenges of the Society 5.0 era.
Microtremor HVSR Inversion for Delineating Weathered Granite Layers: A Case Study from Granit Indah, Lampung
The Horizontal-to-Vertical Spectral Ratio (HVSR) method is an efficient and non-invasive approach for estimating subsurface layer thickness and delineating near-surface geological structures. This study employs HVSRPy, an open-source Python-based tool, to characterize the subsurface stratigraphy of the Granit Indah area in Lampung. Microtremor data were collected at 24 stations using three-component sensors with 30-minute acquisition durations. Processing involved window selection, Fourier transformation, and HVSR curve computation. Dominant frequencies ranging from 0.2 to 5.3 Hz indicate the presence of thick near-surface deposits. Inversion using Dinver resolves three principal layers—topsoil, weathered saprolite, and unweathered granite—with shear-wave velocities of 200–600 m/s. The subsurface model shows strong agreement with Wenner–Alpha resistivity measurements, supporting its reliability. The results demonstrate that HVSRPy provides a robust, time-efficient, and cost-effective workflow for subsurface characterization in regions with limited geophysical data.

Islamic Social Reporting: A Bibliometric Review
This study aims to map the trends and development of Islamic Social Reporting (ISR) research through a bibliometric analysis approach. Data were collected from Scopus, Publish or Perish, and manual searches using the keyword “Islamic Social Reporting,” resulting in 26 articles analyzed descriptively based on publication year, journal quartile, number of authors, topic, method, and citation count. The findings indicate that ISR research is still in its growth stage, dominated by publications in Q4 journals (50%) with a significant increase since 2017. Most studies employ quantitative methods, focusing on factors influencing ISR disclosure, while research on its impacts on performance and corporate reputation remains limited. The overall citation rate is relatively low, showing that ISR has yet to establish strong academic influence. This study is limited by the small number of articles and the absence of visual bibliometric mapping tools such as VOSviewer. Future research is recommended to expand data sources and apply network visualization for more comprehensive insights. Practically, the findings imply that scholars and practitioners should enhance international collaboration and integrate Islamic values into sustainability reporting frameworks
Phytoremediation Technology Using Water Lettuce (Pistia stratiotes) and Blood Cockle Shell Biofilters (Anadara granosa) in the Treatment of Aquaculture Waste
Aquaculture activities with high stocking densities produce liquid and solid waste rich in organic matter, turbidity, and suspended solids. This study aimed to evaluate the effectiveness of the aquatic plant water lettuce (Pistia stratiotes) as a phytoremediator and the blood cockle shell (Anadara granosa) as a biofilter in treating aquaculture wastewater to enhance water quality and reduce nutrient loads. The research employed a Completely Randomized Design (CRD) with two factors: water lettuce density and observation time. Three treatments and three replications were conducted for 30 days. Water quality parameters measured included temperature, pH, dissolved oxygen (DO), nitrate, ammonia, and phosphate. The results showed that the combination of water lettuce and blood cockle shell biofilters with ten clumps of water lettuce was more effective in reducing phosphate levels, while five clumps were more effective for nitrate reduction. Both treatments produced similar plant growth performance, indicating flexibility in system design.
Comparative Analysis of Gender Gap in Smart Farming: Analyzing Women’s Role in the Development of Sustainable Agricultural Practices in Southeast Asia
This study analyzes the gender gap in the adoption of smart farming technologies in Southeast Asia, focusing on the roles of women in the development of sustainable agricultural practices. Despite their significant contributions to food security, women in the agricultural sector continue to face barriers such as limited access to land, technology, and decision-making positions. This research utilizes a qualitative approach by conducting a study report based on official documents, news articles, and international legal frameworks, including reports from organizations such as the FAO, ASEAN, and CEDAW. By reviewing relevant literature and policy reports from ASEAN countries, the study investigates how gender dynamics shape women's participation in smart farming, and the obstacles they encounter in accessing advanced agricultural technologies. The findings indicate that (1) women are disproportionately excluded from access to smart farming technologies due to socio-cultural and economic barriers, (2) gender-sensitive policies in agriculture are insufficient in ASEAN countries, and (3) international legal frameworks, such as CEDAW, have not been effectively implemented at the national level to ensure equal access for women in the agricultural sector. The study concludes that while smart farming offers significant potential for sustainable agriculture, the gender gap in access to these technologies remains a major challenge. Recommendations include strengthening the implementation of gender-focused policies, improving women’s access to agricultural technologies, and integrating gender-specific training and capacity-building programs into national agricultural strategies.

Evaluation of the Formulation of Praxelis clematidea and Soap Nut (Sapindus rarak) Extracts on the Germination of Rottboellia exaltata
Rottboellia exaltata is an invasive weed species that rapidly spreads through seeds and exhibits vigorous growth, leading to severe yield losses in agricultural lands. Weed management through the exploitation of plant allelopathy offers a sustainable approach to controlling such species. Praxelis clematidea and the pulp of soap nut (Sapindus rarak) are known to possess allelopathic properties that can inhibit weed germination. This study aimed to evaluate the effect and identify the most effective formulation of P. clematidea and S. rarak extracts in suppressing the germination of R. exaltata.The research was conducted from July to October 2025 in the Weed Science Laboratory and greenhouse of the Faculty of Agriculture, University of Lampung. A Completely Randomized Design (CRD) with a single factor and six replications was employed. The treatments consisted of different extract formulations of P. clematidea and S. rarak: P0 = control (distilled water), P1 = 50% P. clematidea extract, P2 = 50% S. rarak extract, P3 = 25% + 75%, P4 = 50% + 50%, and P5 = 75% + 25%. Data were analyzed using analysis of variance (ANOVA) after testing homogeneity (Bartlett test) and additivity (Tukey test), followed by the Least Significant Difference (LSD) test at a 5% level.The results demonstrated that both single and mixed extract formulations of P. clematidea and S. rarak inhibited germination percentage and germination rate of R. exaltata. The strongest inhibitory effect was observed with the 75% P. clematidea + 25% S. rarak formulation, which significantly reduced germination percentage, germination speed, root and shoot length, and dry biomass. The inhibitory effect was more pronounced on root growth than shoot growth, indicating that root length serves as a more sensitive indicator of allelopathic effects during germination.
Implementation of E-Book Creation Using a Culture and Civic Literacy Approach in Elementary Schools
The e-book development strategy is a significant initiative designed to improve students' cultural literacy by incorporating local wisdom values into the educational framework. This methodology emphasises the importance of local culture, traditions, and life experiences as essential components for effective pedagogical practices. The initial stage of this process involves identifying relevant cultural elements, such as folklore, customs, regional dialects, and traditional values that are appropriate for the student demographic. These cultural components are carefully integrated into the e-book content, in line with the competencies outlined in the national curriculum. To enhance student engagement, the e-book is developed with interactive features that combine visual, auditory, and video media, thereby enriching the cultural understanding experience. The use of contextual and communicative language fosters a deeper connection between students and the instructional material presented. Additionally, the e-book includes reflective and creative activities, such as cultural projects, documentation of family traditions, or the creation of inspiring folk tales. This pedagogical approach makes the learning experience meaningful, enjoyable, and relevant, while respecting and instilling pride in cultural heritage. As a result, e-books not only enhance academic understanding but also play an important role in shaping students' character and cultural identity in the digital age.
Deep Eutectic Solvents K2CO3–Ethylene Glycol As Extractor Agent for Sago Bark Waste (Metroxylon sago Rottb. L)
Sago starch is a staple food for residents in Luwu Regency, North Luwu Regency, and East Luwu Regency. The increasing demand for sago starch is in line with the deposit of its waste. Unfortunately, sago bark waste has not been widely utilized appropriately. This study utilized a deep eutectic solvent (DES) K2CO3-ethylene glycol to extract versatile solvent candidates from sago bark waste. The research stages began with DES synthesis and followed by sample extraction with the help of sonication and DES solvent. DES synthesis was confirmed through FT-IR, while the compounds in the extract were confirmed through GC-MS. DES was successfully synthesized with the presence of characteristic functional groups of K2CO3 and ethylene glycol in the solvent functional group. From GC-MS analysis, there was a dioxolane compound with 90% similarity. It is assumed that there is an interaction between the DES constituent (ethylene glycol) and the sago bark constituent. Further research is needed to determine the interaction of DES K2CO3-ethylene glycol with other lignocellulosic materials
Identification And Testing The Effectiveness of Bioactive Compounds in Buni Juice as an Antihypercholesterolemic Agent
Buni fruit (Antidesma bunius (L.) Spreng) is thought to be able to treat hypercholesterolemia, a condition where the concentration of cholesterol in the blood exceeds normal and is the main risk factor for Coronary Heart Disease. Scientific data supporting the efficacy of berry as an antihypercholesterolemic agent has not been widely studied, therefore this study aims to examine the chemical compound content and effectiveness of berry as an antihypercholesterolemic agent. Buni fruit juice was tested phytochemically. This study used a Completely Randomized Design (CRD) with 25 mice divided into 5 groups and 5 replications consisting of Negative Control (standard feed), Positive Control (High Fat Diet Food (HFDF) and simvastatin 0.52 mg), P1, P2, P3 (HFDF 14 days followed by 1 ml of 20%, 25%, 30% buni juice 14 days). The parameters measured were LDL (Low-Density Lipoprotein) levels in the blood, which were analyzed using ANOVA and Duncan's test at a 5% significance level. The results of the study, in the form of phytochemical tests, showed that berry fruit contains bioactive compounds, alkaloids, flavonoids, phenols, and tannins. Administration of berry fruit juice at a concentration of 25% was most effective in reducing LDL (Low-Density Lipoprotein) levels in the blood of hypercholesterolemic mice.. Keywords: Antidesma bunius (L.) Spreng., buni fruit, antihypercholesterol, phytochemical test
Analysis of the Movements in Sigeh Penguten Dance Using Labanotation: Benefits and Challenges in Documenting Traditional Dance
This study aims to analyze the movements of the Sigeh Penguten Dance using Labanotation as an effort to document and preserve the traditional dance of Lampung. Labanotation, as a universal movement notation system, provides a structural approach to understanding the dynamics, directions, and qualities of movement in a dance. Through a qualitative descriptive method, this research observes the main movement patterns of the Sigeh Penguten Dance and translates them into Labanotation symbols. The results show that the use of Labanotation can provide a more systematic representation of the movement structure, floor patterns, and classification of dancers’ body movements. The main benefits of applying this notation include ease of documentation, learning, and intergenerational knowledge transfer. However, the study also identifies several challenges, including the complexity of interpreting traditional movements rich in symbolic meaning into a Western notation system, limited understanding of notation symbols among dance practitioners, and the need for specialized training for researchers and dancers. Therefore, integrating Labanotation with contextual cultural understanding is essential to maintain the authenticity and meaning of dance movements. This research is expected to contribute to the development of more scientific and sustainable methods for analyzing and documenting Indonesian traditional dances. Keywords: Sigeh Penguten Dance, Labanotation, Movement Analysis, Dance Documentation, Cultural Preservation.
Promoting Sustainable Development through International Collaborations
Culture is a driver of sustainable development that UNESCO and the world's cities have acknowledged. The UNESCO Creative Cities Network (UCCN) is a platform that gathers and coordinates cities to adopt cultural elements into their local development, transforming culture into creativity that leads to economic growth. Being labeled as the Creative City of Literature, Jakarta, just like other members of the UCCN, is to demonstrate a steadfast commitment to promote culture-based sustainable development, through various programs, one of which is international cooperation. This study aimed to describe the initiatives of international collaborations taken by the city under the framework of the UCCN, employing a qualitative research method with a case study model and a descriptive analysis. The findings show that Jakarta’s international collaborations took shape in three models: hosting international events at home, conducting a joint program with another UCCN member, and participating in international forums overseas. This study offers a perspective that cities in the Global South, rich in cultural heritages, conduct international collaborations as a sign of compliance with the norm of sustainability, strengthening identity within the transnational network mechanism.
HRM Perceptions And Organizational Citizenship Behavior: A Moderated And Mediation Model Of Innovative Work Behavior And Hierarchical Position
This study examines the influence of employees’ perceptions of Human Resource Management (HRM) practices on Organizational Citizenship Behavior (OCB), with Innovative Work Behavior (IWB) as a mediator and hierarchical position as a moderator, within the Indonesian banking sector undergoing digital transformation. A quantitative explanatory design was employed using survey data from 843 employees across top, middle, and lower managerial levels. The study applied Partial Least Squares–Structural Equation Modeling (PLS-SEM) to test the hypothesized relationships. The results reveal that employment security and performance assessment & reward significantly predict OCB, whereas job autonomy, recruitment, and training & development exhibit no direct effects. IWB partially mediates the relationship between HRM practices and OCB, particularly for job autonomy, training & development, and performance assessment & reward. Multi-group analysis further indicates that employment security exerts stronger effects among lower- and middle-level employees, while performance assessment & reward is more salient for top-level employees. The findings extend Social Exchange Theory and the Theory of Purposeful Work Behavior by elucidating the psychological mechanisms linking perceived HRM practices to OCB across hierarchical levels. Practically, the study highlights the need for contextually adaptive HRM strategies to enhance engagement and discretionary behaviors in organizations facing rapid change.
Stability Analysis of Pit B Slope Using RMR (Rock Mass Rating) And GSI (Geological Strength Index) Methods At PT. Halo Tambang Berjaya, Kalianda District, South Lampung Regency
The research area is located at PT Halo Tambang Berjaya, Kalianda District, South Lampung Regency, with the main objective of analyzing slope stability in the open pit mining area using the rock mass rating (RMR) and geological strength index (GSI) methods. The RMR method is used to assess the strength of the rock mass through geotechnical parameters such as intact rock strength, rock quality designation (RQD), spacing of discontinuities, condition of discontinuities, and groundwater conditions. GSI is used to obtain a more detailed picture of the rock mass quality through the structure rating (SR) and surface condition rating (SCR) parameters. The analysis was carried out on one slope in the Pit B area with a 7 meter scanline. The RMR value obtained was 75 (good rock class), and the GSI value was 48 (good rock class). Based on these results, it can be concluded that the slope in the research area is classified as good and stable, so it is relatively safe to support mining activities. However, it is necessary to carry out regular monitoring of geotechnical conditions, especially in slope sectors with close discontinuities, to prevent potential landslides in the future.

Sponges are marine benthic invertebrates from the Porifera phylum that have bioactive compounds that can function as antibacterials. The purpose of this study was to compare the extracts of sponges of the Xetospongia sp. and Spongia sp. against pathogenic bacteria. This study was conducted in May-November 2025. Samples of sponges of the Xetospongia sp. and Spongia sp. taken from the waters of Pahawang Island were extracted using methanol, ethyl acetate and hexane. The results showed that the morphological characteristics the Xetospongia sp. had a rough body surface with a rounded shape and reddish color while the Spongia sp. type had a soft body surface with crusts and a dark black color. The yield of sponge extract using ethyl acetate was greater than using methanol and hexane. The antibacterial activity of sponge extracts against pathogenic bacteria of the Xetospongia sp. used hexane while the Spongia sp. used methanol
ESG Performance and Investment Efficiency in Sharia-Compliant Firms: Evidence from the JII-70
Abstract: This study examines whether Shariah-compliant ESG performance enhances investment efficiency among firms included in the Jakarta Islamic Index 70 (JII-70) and how board characteristics condition this relationship. Using an unbalanced panel of 25 firms consistently listed in JII-70 from 2020–2023 (100 firm-years), investment inefficiency is measured as the residual from an expected-investment model, where lower residuals indicate higher efficiency. Fixed-effects panel regressions with White cross-section robust errors are employed after Chow, Hausman, and diagnostic tests. The results show that ESG scores are negatively and significantly associated with investment inefficiency in most specifications, implying that stronger ESG performance improves capital allocation. Board gender diversity reduces inefficiency on average but weakens the marginal efficiency gains of ESG. Board independence does not significantly moderate the ESG–efficiency link. By contrast, board nationality diversity reinforces the positive effect of ESG on efficiency, while larger boards tend to increase the baseline level of inefficiency. Overall, the findings indicate that governance configuration plays a critical role in translating Shariah-aligned ESG initiatives into more efficient investment decisions among JII-70 constituents. Keywords: Board characteristics, ESG, investment efficiency, Jakarta Islamic Index 70

Performance Evaluation of On-Grid Solar Power Plant in PT.Syntek Automation Indonesia Building
Renewable energy, especially solar energy, plays an important role in creating a sustainable and environmentally friendly source of electrical energy. On-grid Solar Power Plant (PLTS) is one of the effective alternatives to utilize solar energy by converting sunlight into electrical energy, to reduce dependence on fossil energy and allow the supply of excess energy to the grid. This research evaluates the performance of the on-grid solar PV system installed in the PT Syntek Otomasi Indonesia building by assessing the performance of the existing system and redesigning it to increase energy production. The research methodology includes evaluation of the existing system performance, analysis of operational data, and comparison between various orientations and tracker types. Simulation results show that fixed tilt orientations of 3°, 5°, and 10° provide energy production of 7.47 MWh/year, 7.46 MWh/year, and 7.37 MWh/year, respectively, with an average performance ratio of 81%. This study also identified that the existing system is less than optimal in absorbing solar energy due to the variable movement of the sun's trajectory. Redesign using the E-W tracker showed a performance ratio of 80.99% and energy production of 7.88 MWh/year, while the N-S tracker resulted in a performance ratio of 80.75% and energy production of 7.84 MWh/year. These results indicate that the use of the E-W tracker is more optimal than the N-S tracker, with a difference in energy production of 0.055 MWh. These findings recommend the use of E-W trackers to improve the efficiency of the on-grid solar PV system at PT Syntek Automation Indonesia
The Role Of CEO Power In Driving ESG Performance Among IDX Infrastructure Companies
This study examines whether CEO power shapes Environmental, Social, and Governance (ESG) performance among Indonesian infrastructure issuers. Using a balanced panel of 24 IDX-listed firms (2019–2023; 120 firm-years) compiled from Refinitiv ESG and corporate disclosures, we estimate random-effects regressions with robust errors. ESG scores are modeled on CEO tenure, CEO ownership, and CEO duality, with firm size, leverage, and profitability as controls. Results indicate that CEO tenure is positively and significantly associated with ESG, suggesting that experienced—yet non-entrenched—leadership advances sustainability practices. CEO duality shows a positive but statistically insignificant association, while CEO ownership is negative and insignificant. Overall model fit is modest (R² ≈ 0.20), implying that external pressures and broader governance architecture also drive ESG outcomes. The findings highlight the practical role of stable executive leadership in delivering stakeholder welfare through sustainability, while concentrated personal control does not reliably improve ESG performance. Future work should test nonlinearities and governance interactions to address potential heterogeneity and endogeneity.

Influence of Climate Variability (Wave Height, Temperature, and Current Velocity) on Floating Net Cage Aquaculture in South Lampung, Indonesia: Insights from BMKG 2024
This study examines the influence of climate variability on floating net cage (KJA) aquaculture in South Lampung, Indonesia, based on 2024 meteorological and oceanographic data obtained from BMKG Panjang. Three key environmental parameters—wave height, water temperature, and current velocity—were monitored monthly and compared with aquaculture production data collected from local farmers. Results indicated that wave height remained relatively stable (0–0.9 m), while water temperature fluctuated between 27.0 °C in April and 31.5 °C in February and December. Current velocity ranged from 0–10 cm s⁻¹, with the strongest flows recorded between May and July. Fish production varied from 400 to 1,050 kg per cycle, with higher yields observed during periods of stable warm temperatures and lower yields during cooler months accompanied by stronger currents. Temperature and current velocity were identified as the primary climate drivers influencing aquaculture performance. The findings highlight the need for adaptive management strategies—such as site selection, biosecurity improvement, and optimized feeding regimes—to sustain aquaculture productivity under changing climatic conditions.
The Ecological Significance of Diatom Communities in Enhancing Climate Resilience of Seagrass Ecosystems: A Systematic Review (Case of Indonesia)
Seagrass meadows are increasingly recognized as climate‐regulating coastal systems, with their resilience under warming and eutrophication stress is strongly mediated by epiphytic microalgal assemblages. Among these, diatoms constitute the dominant and functionally influential group, particularly in tropical seagrass habitats. This systematic review synthesizes 2005–2025 empirical research on diatom–seagrass interactions across Indonesian coastal ecosystems. Literature screening followed PRISMA guidelines and yielded 27 studies reporting species composition, epiphytic biomass, and associated physicochemical conditions. The dominant seagrass hosts included Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, and Halophila ovalis, which supported recurrent diatom genera such as Navicula, Cocconeis, Amphora, and Nitzschia. Functional interpretation indicates that diatom epiphytes contribute to carbon assimilation, micro‐nutrient retention, and boundary‐layer biofilm stabilization, thereby enhancing seagrass metabolic efficiency under moderate environmental stress. However, at elevated nutrient loads and thermal anomalies, epiphytic proliferation leads to photic shading and suppressed seagrass photosynthetic performance, marking a shift from facilitative to competitive interaction regimes. These findings underscore epiphytic diatom community structure as a sensitive indicator of seagrass functional stability and climate resilience. Integrating diatom‐based bioindicators into seagrass monitoring frameworks is, therefore, essential for adaptive coastal ecosystem management in Indonesia. Keywords: coastal ecosystem; diatoms; epiphytic microalgal, nutrient enrichment; seagrass resilience
The Influence of Learning Duration and Task Type on the Realization of French Connected Speech by Indonesian Learners
one of the most significant features of the French language. The linking phenomena such as liaison, enchaînement, and élision in this language are not found in Indonesian. This poses a particular difficulty for students whose first language is Indonesian in mastering oral competence in French. The purpose of this study is to explain the influence of learning duration (competence) and language practice differences on the realization of these three phenomena. The participants in this study were 44 French language students in their fifth and sixth semesters at the University of Lampung. This study used a mixed-method approach with reading and speaking tests as well as interviews as data collection techniques. Data analysis was supported by the use of PRAAT software. The results showed that, in general, the level of realization was élision > enchaînement consonantique > liaison > enchaînement vocalique. Eliminating was more acquired than inserting sounds in word sequences. In this study, the duration of French language learning (competence) was found to have no effect on the level of realization of the three phenomena. On the other hand, in general, the level of realization of the three phenomena in direct speech was higher than in reading texts. Differences in the phonological system and the transparency of the phoneme-grapheme relationship between the first and second languages, as well as a lack of understanding of concepts and exposure to communication by native speakers, are some of the factors that influence the realization.

Parental income and motivation proved to be the most influential factors influencing interest in continuing studies. These results suggest that the Naive Bayes algorithm can be an effective predictive tool for early identification and educational strategy design, encouraging students to progress to higher levels.
Sensory Quality and Hedonic Level of Sigararutang Arabica Coffee Brew on Varied Processing Treatment
Abstract Sigarar Utang as one of Indonesia's Arabica coffees has superior characteristics such as delicious taste, large bean size and pest resistant. Coffee quality is set during cultivation, but post-harvest processing has a significant impact. Independent processing efforts to generate specialty coffee at the farmer level have the potential to improve farmer welfare. This study aimed to: 1) determine the potential of dry and wet processing (Full wash, Semi wash, Natural, Honey, and Wine) in producing Sigarar Utang specialty coffee and 2) determine the effect of processing and roasting types on consumer preferences. The research was conducted in Gurgur, Toba Samosir Regency, and the Post-Harvest Laboratory of AIAT North Sumatra. The results showed that 4 out of 5 types of processing were able to produce specialty Sigarar Utang coffee. The cupping test results for each processing method were as follows: 85.25 for full and semi wash, 84.75 for honey, 84.5 for natural, and 78.13 for wine. Based on the hedonic test, the highest taste and aroma preferences for each method were 66.6 and 61.9% for light roasting in honey and semi-wash processing; 2) 72.3 and 63.6% for medium roasting in full and semi-wash processing; 3) 63.4 and 81.1% for dark roasting in honey and semi-wash processing and natural and honey. The Friedman test results revealed that the processing method had only a significant effect on the level of preference for the aroma of dark roasted coffee.
Analysis of Dry Waste Combustion Temperature as a Potential Source of Thermal Energy for the Drying Process
Waste management poses a significant environmental challenge, yet dry waste holds potential as a renewable energy source through Waste-to-Energy (WTE) technology. This study aims to analyze the potential of utilizing heat from dry waste combustion for drying applications using a hybrid approach of experimental methods and Computational Fluid Dynamics (CFD) simulation. The experimental stage was conducted by burning dry waste in a furnace to obtain the average hot gas temperature, which was measured at 295.33°C. This value was then used as a boundary condition in the CFD simulation of an integrated heat exchanger system within the furnace. Air at a temperature of 30°C was flowed into the heat exchanger with four mass flow rate variations (0.087, 0.092, 0.126, and 0.165 kg/s). The simulation results show that the system is capable of heating the air to a temperature range of 46.05°C to 58.05°C, which is ideal for drying applications. An inverse relationship was found between the mass flow rate and the outlet temperature, where a lower flow rate results in hotter air. This research proves that the heat recovery system from dry waste combustion is technically feasible and has the potential to be a sustainable alternative energy solution for drying processes.
Relationship Between Household Water Quality and the Incidence of Intestinal Protozoa Infection in Children
Intestinal protozoa infections remain a public health concern, particularly in areas with poor sanitation. One of the main transmission routes is via water contaminated with protozoan cysts. This study aimed to determine the association between household water quality and the incidence of intestinal protozoa infection in children. Data were collected using questionnaires and microscopic laboratory examinations of fecal and drinking water samples. This observational analytic study employed a cross-sectional design involving 50 students. The results showed that 62% of participants were infected with intestinal protozoa. Among children who consumed refillable gallon drinking water, 44.4% were infected, while infection was observed in 71.9% of those who consumed well water. Statistical analysis yielded a p-value of 0.055. Infection prevalence among children whose household drinking water was contaminated was 50%, compared to 63.3% among those whose water was not contaminated (p = 0.52). Conclusion: No significant association was found between household water quality and intestinal protozoa infection; however, there was a tendency toward higher risk among users of well water.

Predictive Modeling of Microbial Growth in Stored Fresh-Cut Green Beans
Microbial growth is a critical factor influencing the quality, safety, and shelf life of fresh-cut vegetables, including green beans. This study aimed to model the microbial growth dynamics of fresh-cut green beans during storage using two nonlinear predictive models: the Modified Gompertz model and the Logistic model. Microbial counts (log CFU/g) were measured over a 21-hour storage period with triplicate observations. Model parameters were estimated using non-linear least squares (NLS) in R, and model performance was evaluated based on residual standard error (RSE), parameter significance, convergence behavior, biological plausibility of parameters, and visual agreement between observed data and fitted curves. The Logistic model produced stable parameter estimates with significant growth-related coefficients and an RSE of 0.6186, whereas the Modified Gompertz model exhibited unstable parameter estimation for μ and λ despite a comparable RSE (0.617). Visual inspection also showed the Logistic model provided a smoother and biologically consistent fit to the observed microbial growth pattern. These results indicate that the Logistic model is more suitable for describing microbial dynamics in fresh-cut green beans under the tested conditions. Overall, this study demonstrates the importance of selecting an appropriate predictive model to accurately characterize microbial behavior in fresh-cut produce. The established model can be applied in shelf-life prediction, risk assessment, and optimization of storage conditions for minimally processed vegetables.
Evolving Research Landscape on Eco-Industrial Parks and Local Commodities: A Bibliometric Analysis (2014–2024)
This study presents a comprehensive bibliometric analysis of research on eco-industrial parks (EIPs) and local commodities published between 2014 and 2024 using the Scopus database. A total of 1,321 documents were analyzed through VOSviewer to explore publication trends, key authors, countries, institutional collaborations, and thematic structures. Results indicate a steady increase in global research output—particularly after 2018—reflecting growing attention to sustainable industrial transformation and circular economy implementation. However, the analysis reveals that no existing study explicitly connects eco-industrial parks with regional development strategies based on local leading commodities. Most publications focus on industrial symbiosis, resource efficiency, and circular economy mechanisms at the industrial park level, while the spatial and economic integration of local resources into EIP frameworks remains unexplored. This study mapping the intellectual and collaborative landscape of EIP research, this study identifies three dominant thematic clusters—industrial ecology and circular economy, sustainability and resource management, and local commodity–based innovation. The findings highlight an urgent need to link EIP research with territorial and commodity-based sustainability, offering a new perspective on how eco-industrial models can foster localized and inclusive regional development.
Religiosity, Religious Identity, and Financial Literacy: The Mediating Role of Moral Values in Trust in Financial Institution and Financial Governance
Purpose Public trust in financial institutions plays a critical role in maintaining financial stability, yet significant trust deficits persist globally, including in Indonesia. This study aims to analyze how religiosity, religious identity, financial literacy, and moral integrity influence institutional trust in banks and the government, with moral values (tax compliance and anti-bribery behavior) serving as mediating variables. Design/methodology/approach Using data from the World Values Survey (WVS) Waves 6 and 7, covering 92.628 respondents across 69 countries, this study employs ordinal logistic regression and mediation analysis to assess the direct and indirect effects of religiosity, financial literacy, and moral integrity on institutional trust. Findings Religiosity positively influences trust in banks and the government, especially through participation in religious services and the importance of religion. Financial behaviours like saving and thrift also enhance institutional trust, while moral deviations such as tax evasion and bribery reduce it. Religious identity alone negatively affects trust, indicating that internalised moral values matter more. Mediation results confirm that financial morality bridges religiosity and institutional trust, emphasizing ethics as the foundation of institutional confidence. Research limitations/implications Although relying on secondary data, this study provides cross-cultural insights into how moral and religious dimensions interact to form institutional trust. Originality/value This study integrates religiosity, moral integrity, and financial literacy into a unified model of institutional trust, providing a multidimensional understanding of how values shape financial credibility and public confidence.
Unresponsiveness of Enhalus acoroides Ethanolic Extract on MDA-MB-231 Breast Cancer Cell Line
Triple negative breast cancer (TNBC) is highly aggressive because it lacks estrogen (ER), progesterone (PR), and HER-2 hormone receptors. Recent anticancer research focuses on natural ingredients to reduce the toxicity of synthetic drugs. E. acoroides is known to contain bioactive compounds that can be cytotoxic to cancer cells. This study aimed to determine the toxicity, cytotoxic, and antiproliferative properties of E. acoroides ethanolic extract against TNBC cell line MDA-MB-231. The methods used includeed Phytochemical Test, Fourier-Transform Infrared Spectroscopy Analysis (FTIR) analysis, Antioxidant Activity Test DPPH (2,2-diphenyl-1-picrylhydrazyl), Toxicity Test with BSLT, Cytotoxic and Antiproliferative Test with WST-8. Based on phytochemical tests, E. acoroides ethanolic extract contained alkaloid, flavonoid, saponin, tannin, steroid, and phenolic. The BSLT results showed E. acoroides ethanolic extract has the LC50 value of 461.576 ppm, categorized as moderate toxic. Antioxidant activity of E. acoroides ethanolic extract indicated low with IC50 values of 858.43 ppm. Then, based on the cytotoxic and antiproliferative test, E. acoroides ethanolic extract has IC50 value of >2000 ppm respectively and do not have antiproliferative activity against MDA-MB-231 cells. These findings demonstrate the unresponsiveness of MDA-MB-231 cells to E. acoroides ethanolic extract, indicating limited anticancer potential against aggressive TNBC cell line.
