This study aims to determine the best carbon particle size and composite variant and to teach students about the making of bio-charcoal briquettes from a mixture of durian peels with banana midribs. This research uses the carbonization methods at a temperature of 200-350oC for 4-8 h to make briquettes with variations in carbon particle sizes of 104 and 250 µm, and in the composition of durian peels and banana midribs of 50:50, 60:40, and 70:30 using adhesive tapioca flour and water in a ratio of 1:2. This study also analyzes the level of students’ understanding through a short survey using 12 pretest-posttest questions supported by learning media using video, where the research subjects are 30 high school students in Indonesia. The results show that the best briquettes obtained from printing using a 19.6 kg compaction load are cylindrical briquettes with a carbon particle size of 250 µm and a composition variation of 70:30. In addition, the results of teaching students show that most students experienced an increase in understanding of briquettes after being given learning through video. This research is important in informing how to use biomass waste into briquettes to solve the current energy shortage problem. © 2020, Rajarambapu Institute Of Technology. All rights reserved.
