Penelitian Pembuatan Arang Bambu (Bamboo Charcoal) Pda Suhu Rendah Untuk Produk Kerajinan

A charcoal formation process occurs when an object is being heated until it reaches its burning point and smoldered, then the oxygen intake is stopped or restricted, so the object will not get burned into ashes. In this research, there are two tipes of furnaces being used, those are: Furnace Tipe-1, with low temperature (120°C) and Furnace Tipe-2, with medium temperature (120°C 260°C), which are made from barrel with 35 cm of diameters. There are 3 tipes of bamboo used in this research, namely: Cendani, Petung, and Legi Bamboo, also semi-finished bamboo products. The procedures are: material preparation (cutting and selection), drying, and measurement of initial water content, charcoal formation process, observation of the process and success rate identification. The objective of this research is for to know the influence the factor of a charcoal formation process at low and medium temperature From the measurement, the initial water content of those 3 tipes of bamboo is under 15%. Meanwhile, from the observation and identification, it obtained that in the charcoal formation process using Furnace Tipe-1, the average highest temperatures reached is 107,4°C during 5 hours, with success rate between 60% - 90%, or 73 in average. In Furnace Tipe-2, the average highest temperature is 112,8°C during 3,5 hours, with success rate between 50% - 90% or 81% in average
