Abstract

Gelam wood is a natural species in swamp forests and is found in many peat swamp forests in South Kalimantan. Due to the abundant availability of gelam wood raw materials in this region and the need for biomass-based energy, wood pellets from gelam wood can be a solution. In this research, an evaluation was carried out on the quality of gelam wood pellets which included calorific value, specific gravity, and pressure test. In addition, an economic analysis of kayu gelam pellets was also carried out. This study used adhesives in the form of tapioca and wheat flour, variations in adhesive percentages of 0%, 5%, 10%, 15%, and powder sizes of 40 mesh, 50 mesh, and 60 mesh. The results of the research show that the calorific value decreases as the size of the gelam sawdust decreases and tapioca adhesive provides the best calorific value. Larger mesh sizes tend to produce higher compression test values and denser specific gravity. From an economic perspective, gelam wood pellets are relatively cheaper and easier to obtain

Abstract

Husnuzan or having a positive prejudice, is an essential concept in Islamic teachings that serves as a form of self-affirmation. This attitude plays an important role in supporting mental and emotional well-being by encouraging individuals to view things with optimism. For students, applying husnuzan in daily life can help them cope with academic pressures, reduce stress, and maintain emotional stability despite heavy academic demands. This attitude also contributes to the development of mental resilience, as students are often faced with situations that require strong mental endurance. Through positive thinking, students can alleviate anxiety caused by various pressures and challenges. However, awareness of the importance of husnuzan in facing life’s challenges remains limited among students. Therefore, efforts are needed to increase understanding and practice of husnuzan among students as a means of supporting their mental health.
