In fact, this waste has a large enough potential to be developed as a raw material for making charcoal briquettes. This research method analyzed the calorific value of 5 (five) treatments using Completely Randomized Design, using 5 (five) repetitions so that the total treatment was 25 (twenty five). The treatment in this study was T0: 100% sowang wood charcoal, T1: sawdust/merbau wood chips (90%) + 10% tapioca flour, T2 : sawdust/merbau wood chips 70% + sawdust/mixed jungle wood chips 20% + 10% tapioca flour, T3: 45% merbau sawdust/wood chips + 45% mixed jungle sawdust/wood chips + 10% tapioca flour, T4: 20% merbau sawdust/wood chips + sawdust/wood chips mixed jungle 70% + 10% tapioca flour. The results showed that T0: 100% sowang wood charcoal produced the highest calorific value, namely 7,619 cal/gram compared to other treatments. The highest calorific value of charcoal briquettes is the T2 calorific value treatment: 70% merbau sawdust/chip + 20% mixed sawdust/jungle wood chips + 10% tapioca flour, with a calorific value of 6,230 cal/gram and charcoal briquettes when it has been produced regularly commercially, grilled fish traders and satay traders are willing to use charcoal briquettes from wood processing industry waste.
