PROPERTY EVALUATION OF CARBONIZED DURIAN (Durio Zibethinus Murr) HUSK BRIQUETTES WITH BANANA PEEL AS BINDER

The main objective of this study is to produce briquettes from carbonized durian husk with banana peeling as binder. The briquette making and combustion tests were done at Mindanao State University. The proximate analysis of briquettes was conducted at the Diagnostic Laboratory of the College of Agriculture, Mindanao State University, General Santos City The raw materials were mixed and proportioned by volume, T, or treatment 1 has 75% of carbonized durian husk and 25% of cassava starch binder, while T, has 70% of CDH and 30% of banana peel as binder. Cassava starch binder served as the controlled treatment where the T, - TA banana peel binder mixtures were compared. T, has a mixture of 65:35 while T, has 60:40 mixture of CDH and banana peel. In proximate analysis, it was observed that T yielded the highest heating value of 24.93 MJ/kg which is the suitable amount for a relatively good quality briquette. T2 and T, followed with 23.49MJ/kg and 23.94 MJ/kg, respectively but on a shatter resistance test, the 2 treatments failed. Treatment 4 got the good result in burning rate but needs a little compaction to pass as a good quality briquette because it tends to fall-off easily. It also has the heating value of 20MJ/kg. Furthermore, the findings that durian husk could be used as substitute to wood fuel were supported with the values of proximate analysis that includes moisture content, ash content, volatile combustible matter, fixed carbon, and heating value. In conclusion, the durian husk briquettes would have a good result with cassava starch as binder. For banana peel as binder, Ty does have a potential but needs more compaction,
