Abstract

The increasing demand for renewable energy has encouraged the utilization of biomass-based solid fuels derived from agricultural waste. This study experimentally compares the combustion performance of coconut shell charcoal and coconut shell charcoal briquettes under controlled laboratory conditions. The evaluation focused on combustion temperature characteristics, burning rate, effective burning duration, and thermal efficiency using the Water Boiling Test (WBT) method. The results indicate that coconut shell charcoal achieved a higher peak combustion temperature of approximately 720 °C and a higher burning rate of 9.6 g/min, reflecting rapid and intense heat release. In contrast, charcoal briquettes exhibited a more stable combustion behavior with a longer effective burning duration of about 78 minutes compared to 42 minutes for charcoal, and a higher thermal efficiency of 31.4%, while charcoal reached 23.6%. These differences are mainly attributed to variations in bulk density, porosity, and combustion kinetics between the two fuel forms. Overall, coconut shell charcoal is more suitable for applications requiring rapid heat generation, whereas charcoal briquettes offer superior performance in terms of fuel efficiency, combustion stability, and sustained heat output, making them a more favorable option for renewable and efficient biomass energy applications.

Abstract

Appropriate technology has emerged as a strategic approach to address community development challenges, particularly in resource-constrained environments. However, many technology-based initiatives fail due to a mismatch between proposed solutions and actual community needs, as well as limited integration of local potential and participation. This study aims to develop a conceptual framework for appropriate technology that is grounded in community needs, local resources, and participatory principles. The study adopts a qualitative and conceptual approach by synthesizing findings from previous literature related to community-based development and appropriate technology. The framework is structured through three main stages: identifying community needs, analyzing local potential and resources, and designing appropriate technology based on user-centered and context-based principles. In addition, the framework incorporates participatory processes and multi-stakeholder collaboration to enhance implementation effectiveness. The results indicate that appropriate technology designed with simplicity, affordability, and adaptability can improve relevance, usability, and sustainability. The integration of local materials, skills, and cultural values strengthens community self-reliance, while participatory approaches foster ownership and increase adoption. Furthermore, the proposed framework demonstrates potential impacts on both economic and social dimensions, including increased productivity, expanded economic opportunities, improved skills, and stronger community engagement. In conclusion, this study highlights that appropriate technology should be viewed not only as a technical solution but also as a strategic tool for empowering communities and supporting sustainable development. A holistic approach that integrates local context, resources, and participation is essential to ensure long-term success and scalability.
