Abstract

As a national marble production center, mining activities in Tulungagung Regency, East Java, contribute significantly to the regional economy. However, behind these benefits come complex ecological and social pressures. This study aims to analyze the impacts of marble mining on local communities and the surrounding ecosystem, and to evaluate environmental restoration strategies through revegetation and tourism development on post-mining land. Using a mixed-methods approach with a case study design, this research combines quantitative surveys, in-depth interviews, field observations, and analysis of supporting documents. The results revel a dilemma: mining increases local incomes and opens business opportunities, but simultaneously triggers land degradation, decreases water and air quality, and changes the community’s socio-ecological structure. Revegetation efforts using local species have proven effective in stabilizing the soil and encouraging the potential for ecosystem recovery. Meanwhile, community-based tourism development facilitated by Village-Owned Enterprises (BUMDes) offers a path to post-mining economic diversification. This integration of ecological rehabilitation and sustainable tourism serves as a strategic model for transforming post-mining land into productive spaces that support the achievement of the Sustainable Development Goals (SDGs). This research emphasizes the importance of an integrated socio-ecological approach in managing post-mining areas.

Abstract

The community service program in Adolang Village, Majene Regency, optimizes the potential of Loka Pere banana as an endemic functional commodity by diversifying products, implementing laboratory-based quality standards, and developing digital marketing. Key interventions include product innovation (Mini Sambusa and Dodol using palm caramel and pandan leaves), proximate-based nutritional standardization, strengthening visual identity, and digital marketing training. Laboratory analysis confirms that the Loka Pere banana is rich in dietary fiber and maintains a stable macronutrient composition, supporting its functional food potential. Evaluation from 33 participants showed very high acceptance (100% positive responses). The program successfully improved product quality, consumer trust, and digital branding capacity, transforming local foods into standardized, competitive functional products. Future efforts should focus on business licensing (NIB, Halal, PIRT) and the cultivation of sustainable raw materials to ensure supply continuity.

Abstract

The research evaluates the operational performance, challenges, and developmental potential of the TPS-3R waste management system in Tangkas Village, Bali, and introduces the SMART–C³ Model as a solution to improve sustainability and operational efficiency. Utilizing a qualitative descriptive methodology, the study gathered data through interviews with key stakeholders, including village officials, TPS-3R managers, sanitation workers, and community members, as well as field observations of waste management activities and document analysis. The results indicate that while the facility handles approximately 38–40 tons of waste monthly, its success is limited by inconsistent household segregation, high residual waste generation, infrastructure constraints, workforce shortages, and weak institutional enforcement. Public participation remains moderate, particularly regarding segregation and recycling efforts. Additionally, the study identifies that although the Organic Waste Recycling Center provides valuable secondary processing, it is not effectively integrated into the overall system. Differing from conventional TPS-3R practices, this study proposes the SMART–C³ Model, which incorporates smart monitoring, cluster-based processing, segregation-based collection, and community-focused behavioral change within a unified circular-economy framework. This scalable, community-driven approach enhances stakeholder participation and resource recovery while reducing reliance on landfills, offering a robust strategy for reaching zero-waste targets in rural and semi-urban regions.

Abstract

This study investigates the effect of carburising holding time on the hardness and microstructure of AISI 1045 medium-carbon steel after quenching. The carburising process was conducted at 900°C using 100% coconut shell charcoal as the carburising medium, with holding times of 15, 30, 60, and 120 minutes. After carburising, the specimens were directly quenched in lubricating oil without reheating. Five specimens were prepared for each treatment condition, and hardness testing was performed according to ASTM E18 using the Rockwell B hardness scale (HRB). Five hardness measurements were conducted on each specimen to ensure repeatability. The results indicate that increasing holding time improved hardness and promoted martensitic transformation due to deeper carbon diffusion. The average hardness increased from 81.46 HRB for untreated specimens to 94.45 HRB for specimens carburized for 120 minutes. ANOVA analysis confirmed that holding time significantly affected hardness values, and regression analysis yielded an R² of 0.962. Microstructural observations revealed increasing martensite formation with longer holding times. The findings demonstrate that carburizing holding time plays an important role in improving the surface characteristics of AISI 1045 steel.

Abstract

Kerupuk or cracker, a popular snack in Indonesia, is typically high in carbohydrates but low in functional components. Surian leaves (Toona sureni), which are rich in antioxidant compounds, have the potential to enhance the functional value of these crackers. However, the stability of these compounds during thermal processing remains largely unknown. This study aims to evaluate the effect of surian leaves addition and each processing stage (raw, boiling, drying, frying) on the proximate composition and antioxidant activity (IC50) of the crackers. This study utilized a factorial Completely Randomized Design (CRD) with two factors: the addition of surian leaves (0% and 16%) and four processing stages. The analyses included proximate composition and the DPPH antioxidant assay. The results showed that the addition of surian leaves significantly increased antioxidant activity (p < 0.001). The processing stages exerted a dominant influence on all parameters: boiling caused the leaching of water-soluble compounds; drying significantly increased protein and ash concentrations; while frying drastically elevated the fat content and was simultaneously the most detrimental stage for antioxidant activity. Despite the degradation, the surian leaves-fortified crackers consistently exhibited significantly higher antioxidant activity compared to the control at every processing stage. It can be concluded that surian leaves are an effective functional ingredient for crackers; however, the processing method is a critical determinant of the final product quality.

Abstract

Coffee is one of the agricultural commodities that has high economic value. Arabica Coffee (Coffea arabica L.) Wanagiri is one of the leading coffee varieties in Indonesia that is now becoming popular because it contains several bioactive components, such as phenolic compounds and flavonoids, antioxidant activity, and very specific aromas and tastes. Coffee production, in addition to producing coffee beans, also produces 55-60% of coffee waste in the form of cherry pulp, cherry husks, parchment, silver husks, and used coffee powder.  The assistance of coffee farmer groups in Wanagiri Village, Sukasada District, Buleleng Regency, is very necessary to produce superior Arabica coffee. The program implementation method includes four stages, namely observation and analysis of needs, program preparation (preparation), implementation (training, mentoring, or counseling), and evaluation and monitoring. This activity concluded that farmer groups now have a better understanding of neat business management and can formulate more modern marketing strategies (digitalization) to increase the selling value of Wanagiri coffee. Farmer groups are able to manage coffee waste (cherry peels/pulp) into products of economic value, such as compost or other derivative products, thereby reducing environmental impact while creating alternative sources of income. The integration between efficient business management and zero-waste management has successfully supported the creation of sustainable agricultural practices in Wanagiri Village, which is in line with green economy principles.

Abstract

This research investigates the influence of various carbon sources (cane sugar, honey, palm sugar) and fermentation durations (7, 10, 13 days) on the chemical profile of a functional drink, kombucha, made from pineapple-fermented cascara. A Completely Randomized Design (CRD) with two factors was conducted to analyze the interaction between two variables. Analyzed parameters include antioxidant activity, total phenolic content (TPC), total titratable acidity (TTA), total sugar, and total dissolved solids. The results reveal that palm sugar combined with a 10-day fermentation period yields the highest antioxidant activity (326.78 mg AAE/L) and TPC (848.76 mg GAE/L). SCOBY microbial metabolism demonstrated significant efficiency, Total titratable acidity (TTA) increased during fermentation, particularly in the sucrose treatment, from 1.92% to 3.33%. In contrast, total sugar decreased from 27.29% to 17.15%. Total soluble solids (TSS) fluctuated during fermentation, with the highest value observed in the palm sugar treatment fermented for 10 days at 13.67°Brix. This research highlights an innovative way to valorise coffee cherry waste into a health-promoting drink by enhancing its flavour through natural fruit fermentation.

Abstract

Rainfall forecasting plays a crucial role in hydrology, agriculture, water resource management, and disaster mitigation. However, rainfall data typically exhibit fluctuating, seasonal, and nonlinear characteristics, which make the forecasting process quite complex. In this study, we propose a hybrid multi-model stacking ensemble to improve rainfall prediction accuracy in Kediri Regency. Our framework integrates statistical models—namely the Seasonal Autoregressive Integrated Moving Average (SARIMA) and Holt-Winters models—with machine learning and deep learning models, specifically Random Forest and Long Short-Term Memory (LSTM). We use Linear Regression as a meta-learner to combine predictions from all base models. The dataset contains monthly rainfall records from 2009 to 2022. Various preprocessing techniques are applied to the dataset, primarily normalization, lag feature construction, stationarity testing, and time-series data transformation, to enable deep learning. We use the Mean Absolute Error (MAE), Mean Squared Error (MSE), Root Mean Squared Error (RMSE), and Mean Absolute Percentage Error (MAPE) to evaluate each model's predictions. In the experiments, the ensemble stacking model outperformed the other models, with an MAE of 28.56, MSE of 1053.26, RMSE of 32.45, and MAPE of 13.05%. The results of the models used in the experiments, including the standalone SARIMA and Holt-Winters models, Random Forest, and LSTM, also showed inferior performance. Our model forecasted rainfall over the next 12 months while preserving historical seasons and data fluctuations, supporting the claim that the hybrid stacking ensemble method optimizes the accuracy, stability, and robustness of rainfall prediction for complex time-series data.

Abstract

Cucumber is a high-value horticultural crop for which stable fruit set and seedless quality are increasingly in demand in intensive production systems. Parthenocarpy induction using gibberellic acid (GA3) offers a practical strategy to enhance yield stability and market preference under limited pollination conditions. This study aimed to evaluate the independent and combined effects of GA.3 concentration and application timing on parthenocarpy success, yield components, and fruit quality in greenhouse-grown cucumber. A factorial completely randomised design tested four GA3 concentrations (0, 100, 200, 300 ppm) and three application timings (pre-anthesis, anthesis, post-anthesis) with three replications. Results revealed that both concentration and timing significantly affected Fruit Set percentage, while their interaction was not significant. Fruit Set increased progressively from control (70.21%) to 300 ppm (87.81%), with anthesis application producing the highest mean Fruit Set (86.97%). Higher GA2 levels (200–300 ppm) improved fruit weight, diameter, length, and flesh thickness, while substantially reducing seed number. The findings indicate a nonlinear dose–response pattern with a tendency toward saturation at higher concentrations. Optimizing GA3 concentration and synchronizing its application with anthesis enhances parthenocarpy efficiency, yield, and commercial fruit quality in cucumber production systems.

Abstract

The purpose of this study is to evaluate the performance of bio-batteries utilizing natural liquid electrolytes made from white vinegar, lime peel, and star fruit. The bio-battery uses copper (Cu) and zinc (Zn) electrodes to function according to galvanic cell principles. With an overall average efficiency of 50% in all test intervals (5, 10, 15, and 30 minutes), composition 47, which consists of 35 ml of lime peel liquid extract, 35 ml of starfruit liquid extract, and 10 ml of white vinegar liquid, is the ideal composition for the bio battery liquid electrolyte. The results show that the electrical power generated ranges from 0.0007 to 0.0008 W, with an average acidity level (pH) of 2.15 and an average conductivity of 3.85 µs/cm. Ion mobility and electrochemical reactions were significantly affected by the electrolyte's characteristics, particularly its high conductivity and low pH. While additional tweaking is required to increase the bio battery's efficiency and electrical power production. This study demonstrates the promise of organic waste as an eco-friendly alternative energy source.
