PEMBUATAN ARANG DAN BRIKET ARANG DARI KA YU MANIS (Cinnamomum burmanii Ness ex. BL) DAN KAYU .SUKUN

Abstract

The aim of this experiment is to find  the properties of cassiavera and, breadfruit charcoal and charcoal briquette.

The kiln  used was the typical size  of 200 liter oil drum  with specie L  design  incorporating 12 holes of  13 mm in diameter  at different elevations. The kiln also had a short chimney of 30 cm high at the top with 10 cm in diameter. The result showed that charcoal yield were 24.74 % for cassiavera and 23.01 % for breadfruit. Volatile matter was 18.61 %,  fixed carbon was 78.31  %  and calorific value was 7035.03 cal/g  for  cassiavera charcoal and volatile  matter was 14.27 %,  fixed  carbon was 73.10 %  and calorific value was 6320.12  cal/g for  breadfruit charcoal

The moisture  content of charcoal briquette ranges from  8.41 to 5. 92 % ash content from  4. 65 to 5. 03  % ,   volatile matter from 28.87 to 29.48 %, fixed carbon from  65.87 to 66.10  %, density from  O.11  to 0.64  g/cm³,  compressing  strength from 275 to 450 kg/cm² and the calorific value from  5684. 59 to 6792.58 cal/g.

Based on the physical and chemical properties, cassia-vera and breadfruit charcoal briquette can be used as sources of energy.
