Abstract

The main process of making biobriquettes is carbonization, namely the formation of biomass into charcoal. Carbonization as charcoal producing tool are being developed today. This is conducted to produce maximum and qualified charcoal. In this research, we have made a prototype of multipurpose tool for carbonization. Besides producing charcoal, we can also utilize its smoke as liquid smoke.This tool is called the Pyrolysis Rotary Carbonisator. This carbonization tool is very effective and easy to use in terms of removing charcoal from the carbonization tool. This design can provide optimal results, that give maximum quantity of charcoal and more evenly heat transfer so carbonization process can be perfect and produce high quality of charcoal as material for bio-briquette. Performance evaluations on the tool proof that it has average efficiency of 90%. Another way of evaluating the work is viewed from the temperature of durian shell, palm shell and coconut shell processing with temperature variation of 200, 250, 300 and 400 o C, we also obtained various maximum heat. From this research, maximum calorie of durian shell charcoal at 400 o C is 5628 kcal/kg, while the palm shell at 300 oC is 7578 kcal / kg and the coconut shell at 400 is 7354 kcal / kg
