<![CDATA[Soybean is a commodity that has an important role in industrial development, especially in the tofu, tempeh, and soy sauce industries. Waste from soybean hulls is still not widely utilized, only used for feed and beverages for cattle. Similarly, durian peels are only utilized for the fruit's meat and seeds, and the peels are thrown away. Product innovation based on durian peels and soybean hulls needs to be implemented to optimize the utilization of these two wastes to increase economic value. The high cellulose content of both wastes can be utilized as raw material for biobriquettes as an alternative to fossil fuelsusing a carbonization process in a chamber furnace at a temperature of 200-250 °C. The higher the ratio of soybean hulls and durian peels produces a high heating value followed by a decrease in moisture content and ash content. The results showed that the biobriquettes from soybean hulls and durian peels have complied with SNI 01-6235-2000. The best condition is obtained by the composition ratio of soybean hulls and durian peels 25:75 (%w/w) with 4 grams of adhesive which produces a calorific value of 5444 cal/g, a moisture content of 4.9%, and an ash content of 6.89%.]]>
