Abstract
Limited fossil energy sources cause the need for the development of alternative energy that is cheap and continuous and can be renewed. One of the raw materials that can be used as an alternative energy source is tea dregs and coconut shell. In this study, a biobriquette printing device was designed with a pneumatic system that uses 7 bar of compressed air from a compressor with 2 mold holes measuring 32 mm in diameter and 16 mm in height, resulting in a force applied to the pneumatic piston to print biobriquettes of 562,688 N. Thrust force cylinder or the force given to push the cylinder so that the cylinder moves forward is 48.7714 kgf while the pull force of the cylinder so that the cylinder moves backwards is 5.9059 kgf with a cylinder moving back and forth speed of 0.0561 m/s. From the design of the pneumatic cylinder diameter of 35.0495 mm, for this study, a cylinder with a diameter of 32 mm with a double acting cylinder was chosen because it required back and forth motion. To move the pneumatic cylinder, air is needed at 3.5596 liters/minute. Making biobriquette mixture of coconut shell tea dregs into biobriquette is carried out through a carbonization process with a fixed variable carbonization temperature of 300°C with a carbonization time of 60 minutes, and the variable variable is the adhesive ratio of 5%; 6%; 7%; 8% and 9%. From the research results, the highest calorific value and has met the standard of SNI 01-6235-2000 at a 5% adhesive ratio of 7047.0253 cal/gr while the water content that has met the SNI 01-6235-2000 standard is 6.00% with an adhesive ratio the sameone.
