Abstract

Waste management has become a critical environmental issue in Bandung Regency due to increasing waste generation and the limited capacity of landfill sites. Improper waste management contributes to environmental pollution, public health problems, and the underutilization of waste as a potential economic resource. This Community Service Program (PKM) aimed to strengthen community capacity and participation in technology-based waste management through collaboration with the Environmental Agency of Bandung Regency by applying Refuse Derived Fuel (RDF) technology. The program was implemented using a participatory approach, including initial socialization and education on waste management and environmental impacts, technical training on the operation and maintenance of RDF machines, and continuous assistance in managing processed waste products with economic value, such as organic compost and plastic pellets. Program evaluation employed a multidimensional impact assessment covering environmental, social, and economic aspects through pre-test and post-test instruments, participatory observation, and activity documentation. The results indicate a significant improvement in community knowledge, awareness, and participation in waste management practices, along with the potential reduction of landfill burden and the creation of new employment opportunities. This program demonstrates that technology-based waste management combined with a community-based waste management approach and circular economy principles can serve as a sustainable solution that delivers environmental, social, and economic benefits for local communities.

Abstract

Despite coffee is one of the leading commodities in Bengkulu Province, the traditional drying process of coffee beans for 10-14 days are still a common practice. This research aims to design, fabricate, and evaluate the thermal performance of a 50 kg capacity wood-fueled coffee drying oven. A three-dimensional CFD model was developed using ANSYS Fluent to analyze temperature distribution within the drying chamber and optimize thermal performance prior to fabrication. Experimental testing was conducted to validate the numerical predictions under controlled operating conditions. The proposed technology is distinguished by its use of locally available biomass fuel. The results of the coffee drying oven simulation, under empty conditions, achieved the desired temperature based. The drying time for coffee beans in this research was 9 hours, achieving a moisture content of 10% to 13% (a moisture content of 12.5% is the Indonesian National Standard. Simulation results predicted chamber temperatures ranging from 67°C to 87°C with an inlet temperature of approximately 100°C, indicating adequate thermal conditions for drying. Experimental measurements showed good agreement with the CFD model, reaching near-steady thermal conditions within 25 minutes.

Abstract

The advancement of composite material technology has significantly contributed to enhancing aircraft structural performance, komponen icularly in terms of weight efficiency and mechanical resistance. This study aims to analyze the influence of fiber orientation on the static response of a composite structure applied to the fairing flap arms component of the NC-212 aircraft. The analysis was conducted through simulation using ANSYS Workbench 2025 based on the Finite Element Method (FEM). The material used is glass fiber fabric/epoxy resin type 181 with various fiber orientation configurations, including (0°, 0°, 0°, 0°), (90°, 90°, 90°, 90°), (45°, -45°, 45°, -45°), (0°, -45°, 45°, 0°), (0°, 90°, 90°, 0°), and (90°, -45°, 45°, 90°). The results indicate that the fiber orientation of (45°, -45°, 45°, -45°) produces the highest Total deformasiof 0.091405 mm and the highest Von Mises stress of 89.132 MPa, along with the highest safety factor of 4.4791. Conversely, the (0°, -45°, 45°, 0°) orientation shows the lowest deformation at 0.07997 mm. These findings emphasize that fiber orientation significantly affects the mechanical behavior of composite structures. Diagonal fiber configurations tend to result in higher deformation and stress levels compared to unidirectional or perpendicular orientations.
