Abstract

Red algae (Gracilaria sp.) have considerable potential as a renewable biomass resource due to their high polysaccharide content, which can be converted into reducing sugars as a feedstock for biofuel production. This study aimed to evaluate the effects of hydrolysis temperature and time on reducing sugar production and to determine the optimum hydrolysis conditions using Response Surface Methodology (RSM). The research variables consisted of hydrolysis temperatures of 100, 110, 120, 130, and 140°C and hydrolysis times of 20, 30, 40, 50, and 60 min. Prior to hydrolysis, the biomass was dried, milled, and delignified using 2% NaOH at 60°C for 3 h with stirring at 300 rpm. Acid hydrolysis was performed using 0.1 N H?SO? under the specified operating conditions. Reducing sugar content was determined by the Nelson–Somogyi method using UV–Vis spectrophotometry. Data analysis was carried out using Response Surface Methodology (RSM), implemented through Design-Expert software. The results showed that both hydrolysis temperature and time significantly affected reducing sugar production. The highest reducing sugar concentration obtained experimentally was 46.57g/L at 120°C and 40 min. RSM optimization predicted an optimum condition at a hydrolysis temperature of 117.7°C and a hydrolysis time of 42.9 min, resulting in a reducing sugar content of 42.72g/L with a desirability value of 0.992. Model validation demonstrated good agreement between the predicted and experimental values, confirming the reliability of the developed model. These findings indicate that RSM is an effective tool for optimizing reducing sugar production from red algae hydrolysis.

Abstract

This study presents the design, fabrication, and performance evaluation of a falling-weight impact testing apparatus for assessing the impact resistance of protective coatings in accordance with ASTM D2794-93: Standard Test Method for Resistance of Organic Coatings to the Effects of Rapid Deformation (Impact). The developed apparatus was designed to overcome limitations reported in previous studies, particularly regarding measurement accuracy, structural stability, and testing repeatability. The testing system was employed to evaluate the impact resistance of coated flat metallic specimens with a coating thickness of 900 ± 100 µm under controlled impact loading conditions. The experimental investigation examined the influence of two impact masses (1.8 kg and 3.6 kg) and three drop heights (0.50, 0.70, and 0.90 m), corresponding to different impact energy levels, on coating performance. The coating response was assessed by analyzing the occurrence and propagation of coating defects, particularly crack initiation after impact loading. The results demonstrate that the developed apparatus provides stable and consistent testing conditions while complying with the dimensional and operational requirements specified in ASTM D2794-93. Furthermore, variations in impact mass and drop height significantly influence the severity of coating damage, indicating that applied impact energy plays a critical role in determining coating resistance. The developed testing apparatus offers a reliable, accurate, and cost-effective alternative for laboratory-scale impact testing of protective coatings on metallic substrates and can support future research on coating performance evaluation and quality assurance.

Abstract

Peat water is characterized by low pH and high concentrations of dissolved organic matter, limiting its direct use as a clean water source. This study aimed to determine the optimum dosages of Poly Aluminium Chloride (PAC) and hydrated lime (Ca(OH)?) for peat water treatment based on physicochemical characteristics. The study employed a laboratory-scale jar test with rapid mixing at 120 rpm, followed by slow mixing at 45 rpm, using various dosages of PAC and hydrated lime. The treatment performance was evaluated based on pH, total dissolved solids (TDS), electrical conductivity, and salinity. The results demonstrated that the combination of PAC and hydrated lime significantly improved the physicochemical characteristics of peat water. The optimum dosage yielded pH values near the recommended range while maintaining acceptable TDS, electrical conductivity, and salinity. These findings indicate that the combined application of PAC and hydrated lime is an effective alternative for improving peat water quality and can serve as a reference for peat water treatment systems Contribution to Sustainable Development Goals (SDGs):SDG 3: Good Health and Well-BeingSDG 6: Clean Water and SanitationSDG 9: Industry, Innovation and InfrastructureSDG 11: Sustainable cities and communities

Abstract

Car-to-car collisions in Indonesia remain one of the leading causes of driver injuries. To date, vehicle safety evaluations have primarily focused on physical vehicle damage and environmental factors, while the characteristics of injuries sustained by drivers inside the cabin based on firsthand experience have rarely been analyzed. This study aims to analyze the relationship between injury severity, the location of the first point of impact, on the body, and the use of passive safety systems as a basis for developing recommendations for Advanced Driver Assistance Systems (ADAS) features. This study uses a quantitative approach based on an online questionnaire distributed to 100 car drivers in Indonesia who have been involved in car-to-car collisions. Data analysis was conducted descriptively using cross-tabulation and the Chi-Square test to examine relationships among injury severity, body impact location, and use of passive safety systems (seat belts and airbags). The results showed that 52% of respondents sustained minor injuries, 36% were uninjured, and 17% sustained severe injuries. The most common impact locations were the upper body (28%) and the head (23%). Statistical test results showed that the use of passive safety systems was not significantly associated with a reduction in injury severity (p = 0.078), but was significantly associated with the location of the impact (p = 0.001), which directly influenced injury severity (p = 0.026). Based on the analytical framework of these injury characteristics, the Forward Collision Warning (FCW), Automatic Emergency Braking (AEB), Intelligent Speed Assistance (ISA), and Proactive Passenger Protection System (PPS) features are recommended as top priorities for ADAS to reduce collision energy prior to a crash.

Abstract

This study aims to formulate a communication strategy for sustainable forest farmer groups (FFG) in Jatimulyo Village, Special Region of Yogyakarta. The study employed a mixed-methods approach with an explanatory sequential design. Quantitative data were collected from 58 respondents who are members of the Wanapaksi FFG and analyzed using SEM-PLS based Importance Performance Map Analysis (IPMA), while qualitative data were gathered from 9 key informants to deepen the analysis results. The results indicate that the sustainability of the FFG is influenced by a participatory communication ecosystem. Based on the IPMA mapping, the indicators identified as top priorities for improvement (Quadrant IV) are the effectiveness of liberating pedagogy, participation (voice), and managerial capacity. All of which are highly important but currently underperforming. The communication strategy is framed within the “Wanapaksi Merekat: Listening to One Another, Managing Wisely, Growing Together Toward Sustainability” program, organised into five operational stages: research, planning, implementation, measurement, and reporting. This strategy focuses on creating safe spaces for dialogue, integrated governance training, and experiential learning to support the achievement of SDG 13 (Climate Action) and SDG 15 (Life on Land).

Abstract

This research aims to empower village women in Ulak Segelung Village through a circular economy approach by transforming organic waste into environmentally friendly biopesticides. Local communities face the dual challenges of high levels of unmanaged household organic waste, farmers' dependence on synthetic chemical pesticides, and women's low economic independence. Using a participatory empowerment model, the program involved 30 homemakers in hands-on training of EM Bokashi anaerobic fermentation technology. The program's effectiveness was evaluated using a One-Group Pretest-Posttest design. The results showed significant improvements in participants' capacity; technical knowledge increased from 48% to 86%, and practical skills rose from 40% to 82%. Environmentally, the initiative increased organic waste collection by 175% (from 8 kg to 22 kg/week). The biopesticide produced (25 liters/week) showed 55% efficacy in reducing pest intensity in local farmlands. Economically, the establishment of the Women's Business Group successfully commercialized the product with 87.5% sales growth in the second month. The study concluded that the program succeeded in creating a circular economy model that reduces environmental pollution while providing a new independent source of income for village women. The study recommended standardizing product legality and expanding market networks.
