Analisis Kadar Zat Menguap dan Kadar Karbon Terikat Pada Briket Eceng Gondok – Sekam Padi

Water hyacinths are aquatic weeds that have negative impacts of social, economical, and environmental. Water hyacinth has not been widely used as a renewable energy. Aim of this research is to analyze volatile matter content and fixed carbon content at renewable energy sources in the form of water hyacinth – rice husk briquette. The research design is experiment using Factorial Complete Randomized Design (3x3) with two factors; the charcoal combinations of rice husk : water hyacinth and the percentage of tapioca binder. This experiment is repeated 3 times, so there are 27 treatments. The calculation of volatile matter content using ASTMD-3175 standard and the calculation of fixed carbon content using ASTMD-3172 standard. The results show that the lowest volatile matter content (50.5%) and the highest fixed carbon content (20.3%) are owned by briquette A1P3 (combination of rice husk : water hyacinth 1:1 and the percentage of tapioca binder 5%). That briquette is not appropriate with the standards of charcoal briquette (SNI 01-6235-2000
