Abstract
The purpose of this study is the use of bus wood trees as fuel for aluminum smelting for the home industry because it has a good heating value and is very efficient, from the laboratory test results, the bus tree wood has a calorific value of 5981 (calories/g). The methods used experimental and analytical to get the results from the use of bus wood as fuel for aluminum smelting which will certainly produce good mechanical properties. The results obtained a good combustion process that releasing all the heat contained in a fuel and done with three combustion control processes, including a fairly high temperature to ignite and maintain the flame of the fuel, turbulence or mixing O2 and the use of good fuel and sufficient time to complete combustion process. The fuel (bus wood) which is inputted in the furnace is designed so that the combustion process takes place more completely with minimal heat losses. The results of temperature changes seem a thermocouple and crucible furnace insulator material were very good heat resistance hence the time of the melting process it doesn't take longer which is 15 minutes. The aluminum in crucibles has melted at a temperature of 723℃.
Highlights
Merauke regency is the easternmost region of the Unitary State of the Republic of Indonesia and is one of 29 regencies/cities in Papua Province, this regency borders directly with the State of Papua New Guinea
Bus wood is a typical wood of the Merauke district, which is certainly used as local fuel for the people of Merauke because it has a good calorific value from the results of laboratory tests of 5981, bus wood has an economical price to be used as fuel for smelting metal
Kerosene and diesel fuel are currently rather difficult to procure and the price is relatively high, if reidu oil is used the risk of air pollution is higher, so using wood-fueled buses certainly does not require a large cost because bus wood is widely available in Merauke district and continues to be preserved by the local government aside from being a fuel it produces oxygen for people who live in Merauke district
Summary
Merauke regency is the easternmost region of the Unitary State of the Republic of Indonesia and is one of 29 regencies/cities in Papua Province, this regency borders directly with the State of Papua New Guinea. The process of melting aluminum metal can be done with wood charcoal, coconut shell charcoal, coal briquettes, kerosene and LPG gas using a simple crucible furnace. This furnace does not produce ash from combustion. Kerosene and diesel fuel are currently rather difficult to procure and the price is relatively high, if reidu oil is used the risk of air pollution is higher, so using wood-fueled buses certainly does not require a large cost because bus wood is widely available in Merauke district and continues to be preserved by the local government aside from being a fuel it produces oxygen for people who live in Merauke district. Making molds and patterns does not require expensive special equipment
