Abstract
The utilization of nipah frond waste (Nypa fruticans) and galam bark (Melaleuca leucadendron) as materials for making briquettes has been carried out. Nipah fronds and galam bark were obtained from Bunipah Village, Banjar Regency, South Kalimantan. This study used an experimental method with a percentage variation of nipah frond and galam bark composition of 100:0, 75:25, 50:50, 25:75 and 0:100. The adhesive used was 20% resin, with a pressure of 200 kg/cm2 and was dipped in used cooking oil for 30 seconds. This study aims to determine the characteristics and quality of briquette combustion. The results showed that the characteristics of briquettes produced water content of 4.31-8.03%- ash content of 3.69-10.00%- bound carbon of 39.55-42.29%- calorific value of 6,854.71-7,689.51 cal/g, density of 0.78-0.83 g/cm3. While the quality of briquette combustion produced initial ignition time of 2.19-2.56 minutes- combustion duration of 91.47-129.24 minutes and combustion speed of 0.19-0.15 g/minute. Based on the test results, briquettes with a composition of 75:25 (75% galam bark: 25% nipah fronds) have the best characteristics and combustion quality compared to briquettes with other compositions.
