Abstract

Pemanfaatan energi matahari pada solar water heater (SWH) berusaha dikembangkan, terutama untuk meningkatkan kinerjanya. Kinerja SWH dipengaruhi oleh energi radiasi matahari yang dapat diterima oleh pelat penyerap melalui kaca penutup. Dengan demikian model kaca penutup merupakan hal yang penting untuk mengoptimalkan energi radiasi matahari yang dapat diterima oleh pelat penyerap. Penelitian ini bertujuan untuk mengevaluasi kinerja SWH dengan kaca penutup model piramida yang dibandingkan dengan model standar. Penelitian SWH dilakukan secara eksperimen dengan variasi laju aliran air (0,05; 0,15; 0,25 liter/menit) selama 15 hari. Parameter seperti temperatur kaca, pelat penyerap, air keluar, serta efisiensi SWH dianalisis secara komparatif. Hasil penelitian SWH ini menunjukkan bahwa kaca penutup model piramida memperoleh efisiensi tertinggi sebesar 49,41%, meningkat hingga 6,59% dibandingkan kaca penutup model standar. Desain demikian kaca penutup model piramida lebih efektif dalam meningkatkan radiasi matahari yang dapat diterima oleh pelat penyerap dibandingkan kaca penutup model standar

Abstract

The purpose of this activity is to improve the skills of participants, especially housewives, in processing wood waste into products with sales value, while empowering them economically and socially. The methods used include three main stages: planning, implementation, and evaluation. In the planning stage, training needs are identified, materials are prepared, and tools and materials are procured. Implementation is carried out through the delivery of theoretical materials and direct practice, where participants are trained to process wood waste into products such as plaques and wall decorations. Evaluation is carried out qualitatively through interviews and open questionnaires to understand the experiences and perceptions of participants. The results show that the majority of participants felt that this training was very useful, although there were suggestions to extend the duration of the practical sessions. Participants also showed good abilities in producing creative products that have the potential to provide additional income. The implications of this activity are an increase in skills and economic opportunities for participants, as well as a positive contribution to the environment through the utilization of wood waste. This training also shows that a practice-based approach is very effective in developing new skills in the creative economy sector.
