Abstract

Argosari Village faces a critical waste management challenge due to the accumulation of biogas slurry (300–500 kg/day), household waste (687 kg/day), and agricultural waste (1,919.7 kg/day). Limited public awareness and waste processing capacity have led to uncontrolled environmental pollution. This community service program introduces the Octane Cycle Concept, a novel and integrative waste utilization model that transforms both organic and inorganic rural waste into valuable products such as compost, fertilizers, fish feed, mushroom media, and handicrafts. The Octane Cycle emphasizes a closed-loop, multi-output processing approach that links food, energy, and local economy in a zero-waste framework. The program was carried out in five phases: preparation, equipment provision, community training, monitoring and evaluation, and reporting. Results show that waste volume in Argosari Village was reduced by 51% within three months. In addition to improving environmental cleanliness, the program fostered entrepreneurship and increased household savings through the production of bio-based products. This model demonstrates the scientific and practical potential of applying circular economy principles at the village level.

Abstract

The use of waste as an alternative fuel is being continually developed to support the clean energy transition. Orange peel oil (OPO) contains limonene, a volatile hydrocarbon compound with double bonds that has the potential to be used as a gasoline additive. However, studies directly examining its effect on droplet combustion characteristics are still limited. This study aims to fill this gap by evaluating the droplet combustion dynamics of a mixture of low-octane gasoline and OPO through visual and thermal approaches. Experiments were conducted by burning 10 µL droplets using a metal stand, with the essential oil concentration varying from 1% to 100%. Visualization was performed using a high-speed camera, and temperature measurements were carried out with a K-type thermocouple. The results showed that the addition of OPO prolonged the combustion time, decreased the combustion rate constant, and increased the maximum temperature. Microexplosions were observed starting at concentrations ≥25%, due to differences in boiling points between the components. Flame visualization confirmed the quantitative results, with brighter and longer-lasting flames at higher concentrations. This study concludes that OPO can significantly modify the droplet combustion characteristics and shows potential as a waste-based biofuel additive, which can improve the efficiency and sustainability of gasoline combustion systems

Abstract

The gradual elimination of asbestos in brake pad manufacturing has intensified the search for sustainable and non-toxic friction materials. This study presents waste-based bio-composite brake pads reinforced with mahogany sawdust and brass shavings, fabricated using a compaction-sintering approach. The scientific novelty of this study lies in the combined influence of reinforcement composition and compaction pressure on the microstructure-hardness relationship of wood-metal hybrid composites for brake pad applications. The effects of varying mahogany-to-brass ratio and compaction pressure on Shore D hardness and morphological characteristics were systematically evaluated. The results showed that increasing compaction pressure and reinforcement proportion improved composite densification and interfacial bonding, thereby increasing hardness. Increased hardness indicates better structural integrity and load-bearing capacity, which are important mechanical requirements for brake pad materials. The highest hardness value of 76.6 Shore D was obtained at a pressure of 3400 psi with a 4:4 composition, while the lowest value of 70.6 Shore D occurred at 3000 psi with a 1:4 ratio. These findings highlight the role of controlled compaction and balanced hybrid reinforcement in tailoring the mechanical characteristics of sustainable brake pad composites, supporting the potential utilization of wood and metal waste as environmentally friendly friction material components.

Abstract

Savonius wind turbines belong to the class of vertical-axis wind turbines (VAWTs) and are well known for the ability to self-start at low wind speeds without the need for yaw control. Despite these advantages, their aerodynamic efficiency remains lower than that of horizontal-axis wind turbines (HAWTs). In this study, the flow structures and performance characteristics of a Savonius wind turbine are examined using streamline visualization under varying wind speeds ranging from 8 to 10 m/s and blade angles between 100° and 130°. The Reynolds number variations reflect changes in the flow regime and momentum exchange caused by different wind speeds and blade orientations. Across all wind speeds, the 120° blade angle consistently resulted in the most favorable flow conditions. Streamline visualization highlights key flow features, including flow separation, vortex development, and wake structures, which play a critical role in determining aerodynamic efficiency and energy capture. By directly relating Reynolds number variations to observable flow phenomena, this study offers practical insights for aerodynamic optimization. The findings contribute to the development of more efficient Savonius wind turbine designs, particularly for applications in low to moderate wind environments.

Abstract

Low renewable energy literacy among students remains a challenge in supporting energy transition and sustainable development. This community service program aimed to improve renewable energy literacy through solar panel education and training for students at SMP Negeri 8 Probolinggo. A quantitative descriptive approach with a pretest posttest design was employed. The program involved 30 ninth grade students who participated in interactive workshops on renewable energy concepts, counseling on the role of green energy in reducing carbon emissions, and hands-on practice in basic solar panel installation and maintenance. Program outcomes were evaluated using a five-point Likert-scale questionnaire consisting of 20 statements grouped into seven assessment parameters. The results showed consistent improvements across all parameters, with percentage increases ranging from 10.7% to 39.3%. The highest improvement was observed in the maintenance and evaluation of solar panels, while the lowest increase occurred in students’ attitudes toward supporting renewable energy. These findings indicate that practice-based educational interventions are effective in enhancing students’ knowledge, basic technical skills, and environmental awareness. This program contributes to the achievement of Sustainable Development Goals, particularly SDG 4 (Quality Education), SDG 7 (Affordable and Clean Energy), and SDG 13 (Climate Action).

Abstract

The growing demand for electrical energy and the limited supply of fossil fuel resources have driven the development of energy collecting devices as sustainable sources of alternative energy. One interesting solution is to gather the mechanical energy created by passing vehicles and turn it into electrical energy via speed bump energy harvesting. The study is intended to analyze the static structural features of a speed hump by applying the FEA approach using SolidWorks Simulation 2023. The analysis was performed on two key components: the speed bump pad and the supporting frame constructed of steel AISI 1020. Von mises stress, strain, displacement and safety factor were studied. Simulation findings showed that the maximum stress on the speed bump pad is 8.814 x 105 N/m^2, maximum strain is 3.196 x 10-6, and the minimum safety factor is 398.9. At the same time, the maximum stress of the supporting frame was 1.578 × 10⁵ N/m², the maximum strain was 2.683 × 10⁻⁵ and the minimum safety factor was 50.31. The stresses were well below the yield strength of AISI 1020 steel, indicating safe structural behaviour with no permanent deformation. The analysis shows that the proposed design is physically reliable and applicable as an energy collecting system in sustainable transportation infrastructure.
