Abstract

Utilization of briquettes as an alternative biomass energy source is possible. Biomass is a renewable energy source that is becoming increasingly important throughout the world. This has the potential to reduce human dependence on fossil fuels. This research aims to determine the effectiveness of reducing the water content and density values of areca nut shell briquettes. The raw materials used in making briquettes are areca nut shells and arpus adhesive, with each percentage of material and adhesive composition, namely sample A (55% : 45%), sample B (60% : 40%), sample C (65% : 35%), and sample D (70% : 30%). The results of this research obtained a water content value of 6.36% - 4.82% and a density value of 0.534 g/cm3 - 0.599 g/cm3. This water content value meets SNI 01-6235-2000 regarding wood charcoal and these briquettes are suitable to be used as a substitute for charcoal on a household scale.

Abstract

This research aims to determine the characteristics of coconut shell activated carbon in powder and granular form using quantitative methods. Making activated carbon consists of preparation, carbonization and activation. Then the physical properties were tested and the analysic. Actived carbon is made through a carbonization stage at a temperature of 400°C for 2 hours and activation at a temperature of 800°C, 900°C, and 1000°C for 1 hour. The parameters used are air content and volatile substance content with active carbon quality requirements based on SNI No. 06-3730-1995. The research results showed that the best quality powdered activated carbon at a temperature of 1000°C with an air content of 6.4% and a volatile matter content of 15.2%
