Abstract
<p>The study aimed to determine the rendement of charcoal and wood vinegar and to identify wood vinegar chemical compounds made from ironwood deliquent waste. The study was carried out by using charcoaling facilities at the charcoaling center in the village of Asam – Asam. The charcoal and wood vinegar rendements were determined after ironwood delinquent waste was heated for 21 days with a temperature of approximately 400 - 600 ºC. The results showed that the rendement of the charcoal and wood vinegar were 14.02% and 0.05%, respectively. The research with wood vinegar characteristic before purification was pungent, however after purification, the results did not sting; color pH before purification was blackish-brown, however after purification it was pale brown yellow; the specific gravity before purification was 1.012 and after purification, it was 0.97; the pH before purification is 3.63 and after purification 3.41; and acid content before purification was 3.73% and after purification it was 3.66%. As a whole, the physics test of wood vinegar is categorized in Japan standard, however, the color only before purification is not standard. There are five chemical compounds identified in wood vinegar both before and after purification.</p>

Data on the result of research on charcoal and wood vinegar rendement can be seen in the following Table 1
The wood charcoal rendement obtained in this study was 14.02% and wood vinegar rendement obtained was 0.05%
Summary
International world concerns about the phenomenon of global climate change are increasingly high due to rising global temperatures known as global warming. Global warming occurs due to increased emissions of greenhouse gases such as carbon dioxide (CO2), methane (CH4), Nitrous oxide (N2O), and Chloroflourcarbon (CFC). These gases are excessive to the atmosphere so that sunlight reflected to Earth. Most of sunlight is reflected back to earth by the greenhouse gases formed in the atmosphere so that this further increases the temperature of the earth (Latuconsina, 2010). It requires efforts to change the gases into liquid smoke (known as wood vinegar) through pyrolysis technology, namely thermal degradation technology for making charcoal (carbonization) without using oxygen in the manufacturing process with a temperature of 400 - 600 oC
