BRIKET ARANG KULIT KACANG TANAH DENGAN PROSES KARBONISASI

Abstract

The Peanuts peel can be converted to charcoal through  the carbonization process with tapioca moulded as adhesive. Making  briquettes from peanut peel is usefull as an alternative fuel. Peanut peel were cutted in two parts and dried in open air.  Next, it were carbonized in 200 ⁰C, 225 ⁰C, 250 ⁰C, 275 ⁰C and 300 ⁰C and 300 ⁰C for 90 minutes. Then the charcoal ware pounded and sieved to make it in uniform size (40 mesh). Then it was weighed in 25 grams, 50 grams, 75 grams, 100 grams and 125 grams. And then mixed with adhesive moulded. The moulded briquettes were dried through the air for 24 hours and then it were heated in the oven with 100 ⁰C for 1 hour. Then the briquettes were analyzed calorific value, ash content, water content and color of flame. Finally, the highest calorific value of charcoal briquettes was on the composition of peanut peel 75 grams and 250 ⁰C, it give 6536.98 kcal / kg. The lowest water content in the composition of 125 grams and 300 ⁰C, it give 2,014%.  And the lowest ash content generated in the composition of 75 grams and 200 ⁰C, it give 7,39%.
