Abstract

Upaya untuk mencari bahan bakar alternatif terbarukan (renewable) yang ramah lingkungan dilakuan berkelanjutan untuk mengurangi ketergantungan pada bahan bakar fosil dalam keperluan rumah tangga khusnya minyak tanah. Salah satu energi terbarukan yang memiliki potensi besar di Indonesia yaitu biomassa. Dengan memenfaatkan limbah serat pinang dan tapioka menjadi briket telah membantu pemerintah dalam mengatasi masalah limbah. Penelitian ini bertujuan membuat briket dengan variasi campuran bahan baku dan perekatnya, 90% : 10%, 80% : 20%, 70% : 30%, 60% : 40% serta mendapatakan nilai kalor dan densitas. Hasil penelitian 80% serat pinang 20% tapioka memperoleh nilai kalor 12352,9 Kj/Kg serata densitas dari variasi ini sebesar 318,71 Kg/m3. Semakin tinggi nilai kalor bahan bakar maka semakin baik bahan bakar tersebut. Briket serat pinang perekat tapioka dapat dijadikan sebagai bahan bakar, karena memiliki nilai kalor yang tinggi

Abstract

The utilization of biomass as an alternative fuel is becoming increasingly important amid growing dependence on fossil energy and the abundance of plantation waste in Indonesia. Although briquettes made from palm kernel shells and coconut shells have been widely studied, research that specifically examines the effects of variations in material composition and carbonization temperature using tapioca as a binder remains limited. This study aims to analyze the characteristics of mixed briquettes made from palm kernel shell charcoal and coconut shell charcoal and to determine the optimum composition as an alternative fuel. A quantitative approach was employed with a laboratory experimental design involving variations in material composition (85%:15% and 80%:20%) and carbonization temperature (550 °C and 600 °C). Data were obtained from tests of moisture content, ash content, and calorific value using a bomb calorimeter and were analyzed descriptively and quantitatively. The results show that briquettes with a composition of 80%:20% yielded the best characteristics, with the lowest moisture content of 25%, ash content of 10.01%, and the highest calorific value of 29.994 kJ/kg. These findings confirm that optimizing material composition and carbonization conditions plays a crucial role in producing biomass briquettes that are suitable for use as alternative fuel, thereby contributing to the development of biomass waste utilization as renewable energy with potential applications at the household and small-scale industrial levels.

Abstract

Blended learning using Google Classroom is a combination of face-to-face and online learning that utilizes the Google Classroom platform to facilitate interactions between students and teachers outside the classroom. This study aims to assess the effectiveness of implementing blended learning using Google Classroom. The study employs a quantitative method with a descriptive research design. It involves 27 students from the Grade XI Industrial Mechanical Engineering program at SMK Negeri 1 Sumatera Barat. Data collection was conducted through questionnaires and documentation The questionnaire in this study assessed five aspects: the use of Google Classroom, interaction in learning, technological accessibility, comfort and satisfaction, and the effectiveness of blended learning. The analysis results for each assessed aspect were as follows: the use of Google Classroom at 76.66%, interaction in learning at 71.29%, technological accessibility at 75.37%, comfort and satisfaction at 70.74%, and the effectiveness of blended learning at 68.51%. This indicates that students’ overall response to the effectiveness of blended learning using Google Classroom was 73.19%, categorized as effective.
