| dc.description.abstract | Alternative energy can be produced from appropriate technologies such as charcoal briquettes by utilizing biomass
waste from corn stalks and charcoal from wood charcoal from secondary forest fires. This study aims to find the
best combination of raw material composition of charcoal briquettes from a mixture of corn stalk charcoal powder
(Zea mays) with wood charcoal powder from secondary forest fires that can produce the best quality charcoal
briquettes. The process of making charcoal briquettes is done by mixing the two ingredients of charcoal powder
with adhesive then printing and pressing. Data processing in this study used RAL (completely randomized design)
with 5 treatments (A) 100% corn stalks and 0% secondary forest wood, (B) 75% corn stalks and 25% secondary
forest wood, (C) 50% corn stalks and 50% secondary forest wood, (D) 25% corn stalks and 75% secondary forest
wood (E. 0% corn stalks and 100% secondary forest wood) with 5 replications each. If the results obtained have a
significantly different effect, a further LSD (Least Significant Differencen) test will be carried out. The composition
of the best treatment on the quality of charcoal briquettes was found in treatment E with a density value range of
0.514 g/cm3, water content 7.720%, compressive strength 54.224 kg/cm2, volatile matter content 35.030%, ash
content 4.064%, bound carbon content 60.934% and calorific value 6,371 cal/g. Some test results have met the
quality reference of charcoal briquettes according to the Center for Research and Development of Forest Products
(P3HH) and SNI (No. 01-6235-2000). | en_US |
