“…The video does not only describe the content but also contains fascinating pictures and back-sound music that help student's understanding of the material. This finding is also in line with the study where the use of audio-visual media itself has increased student understanding since it can supplement students' basic experiences and describes a process accurately and repeatedly (Alfiani, 2020) and the improvement in cognitive value (N-gain) of students experiencing an increase in N-gain using audio-visual media is also observed (Suryani, Farid, and Mayub, 2019).…”

“…Biobriquette is an alternative energy substitute for fuel produced from underutilized organic or agricultural waste (biomass) (Martynis, Sundari, and Sari, 2012). In line with the literature on the production of biomass briquettes from a mixture of peanut shells and corncob, charcoal shows that briquettes are effectively used as a renewable alternative fuel source (Purnawarman, Nurchayati, and Padang, 2015) and that there is an increase in cognitive value (N-gain) for students which is marked by an increase in N -gain (Suryani, Farid, and Mayub, 2019).…”

“…Menurut penelitian Irhamni (2019), kulit durian mengandung lignin (15,45%), hemiselulosa (13,09%), dan selulosa (60,45%) [14], menurut penelitian Suryani, dkk. (2019) dengan komposisi 20% kulit durian dan 80% tempurung kelapa didapatkan nilai kalor paling tinggi sebesar 7306,81 kal/gram dan kadar air sebesar 20,8% [15]. Nilai kalori briket durian menurut Nuriana, dkk.…”

“…RDF-5, for example, is derived from combustible waste and is produced in granular, slag, or pellet forms. The advantages of RDF include its ability to be stored for extend periods, its practically in transportation, and its high calorific value ranging from 3,000-7,000 Kcal/Kg (Putri & Sukandar, 2013;Suryani et al, 2019).…”
