Abstract

A substantial amount of coffee plantation waste is generated in Aceh highland, yetits utilization remains limited. Most of the wastes are dumped on the ground, whilecoffee parchment is often burned without further application. This study exploresthe conversion of coffee parchment into briquettes, focusing on their combustioncharacteristics. The parchment were subjected to torrefaction process attemperatures ranging from 240°C to 270°C and then ground to particle sizes of 40,60, and 80 mesh. Briquettes were formed using 10% tapioca flour as a binder andcompressed simultaneously for 20 pieces of briquettes at pressures of 300, 400,and 500 kg/cm². The resulting briquettes, with dimensions of 37×28×28 mm,exhibited a density of 0.63 g/cm³ and a combustion rate of 0.37 g/min, enabling aburn duration of up to 105 minutes and a peak temperature of 435°C. The bestperformance was achieved using a particle size of 60 mesh and a compactionpressure of 400 kg/cm². These findings demonstrate the potential of coffeeparchment as a viable source of solid fuel for heating applications.

Abstract

Student well-being plays a crucial role in academic success, particularly in challenging subjects such as physics. It encompasses school-related, social, emotional, and academic aspects that interrelate to foster an optimal learning experience. This study aims to investigate the relationship between student well-being and achievement in physics learning while offering insights for educators to develop a supportive learning environment that enhances student well-being. The method employed in this article is a Systematic Literature Review (SLR) based on the PRISMA 2020 protocol. Data were gathered from articles published over the past six years, sourced from the Scopus database. The findings indicate that supportive learning environments, such as classrooms and laboratories, indirectly influence physics learning outcomes. Emotional well-being, including the ability to manage stress and maintain intrinsic motivation, directly impacts student engagement in physics education. Furthermore, social support from teachers and peers significantly contributes to boosting students' self-confidence. This research confirms that student well-being not only affects academic success but also fosters essential social and emotional skills.
