Analisis Proksimat Karbon Kulit Kemiri (Aleurites moluccana) dengan Variasi Suhu Karbonisasi

Abstract

Candlenut (Aleurites moluccana) is a plant with various benefits. Currently, candlenut is mostly used as a spice, candlenut shells also has a high calorific value so that it can be used as fuel. Candlenut has shells which is an organic waste. Candlenut shells have a hard texture and high carbon content. Most of the candlenut shell is used as fuel and only a small part is used as raw material for carbon production. Candlenut shell have good physical and chemical properties as carbon raw materials. Activated carbon is one of the carbon phases that can be used for various applications. In this paper, we report on the synthesis and characterization of carbon from candlenut shells to obtain high-quality carbon by controlling the carbonization temperature. In carbon production, we use variations in carbonization temperatures of 300, 400, 500, 600 and 700 C. Proximate analysis was carried out to determine the moisture content, ash content, volatile matter content and bound carbon content. Analysis of the effect of carbonization temperature on the quality of carbon from candlenut shells resulted in the highest carbon in the sample with a temperature of 700 C, producing carbon with 5.32% moisture content, 9.40% ash content, 12.76% volatile matter content, and fix carbon content 72,52%
