Abstract

Basic Chemistry course is a compulsory course for students of the Department of Mathematics and Science Education . In the syllabus there is Thermochemical subject. It discussed the changes in thermal energy that occurs from a chemical reaction system. Energy changes that occur in exothermic or endothermic reactions. In exothermic reaction, it used the explanations and examples from textbooks, which is a common example that did not pay attention to the natural resources that existed in that place. Basic chemistry course with the subject thermochemical which discussed South Sumatera?s potential ? oil, gas, and coal that need to be developed so that learning became more useful. Those resources are abundant fuel in South Sumatra. Researcher has been conducted research about potential areas of southern Sumatra, which is about Coal. The results of this study used by the researcher to develop teaching materials Basic Chemistry Course with the subject Thermochemical with Bio-Coal Briquette South Sumatra. Coal is a fuel source that is abundant in South Sumatra . Almost all districts in South Sumatra has reserves coal, although only a few districts that have been exploiting coal; Muara Enim, Lahat, OKU, MURA and Banyuasin. South Sumatra coal quality is generally low, the type of lignite to subbitumitas (5000-6500 kcal/kg). The main use of coal is as PLTU fuel. With the depletion of oil reserves, Indonesian government eliminated household kerosene subsidies, and transfers to other fuel substitute for oil , which is a gas. Gas fuel prices are relatively more expensive, so we need to find an alternative. As an alternative to kerosene besides gas is coal briquettes. Briquette is a block of material that can be burned. Briquettes Coal briquettes are made from coal fuel. Coal Briquette is a fuel that is cheaper than gas, easier to use, and available in South Sumatra, because there is a briquette factory in the same city where coal mining. Coal briquettes is still less than the wider use of gas. This is due to coal briquettes is more difficult than the gas ignited. Researcher has conducted research that coal briquettes easily ignited. The research conducted is doing blending coal with durian peel fiber as a stimulant ignition. Coal briquettes produced bio -coal briquettes called, because of added fiber of durian leather ( a bio/plant ) in the manufacture of coal briquettes. Has studied various forms of bio -coal briquettes, coal composition -fiber of durian leathers, fiber position and coal briquettes. The results of the research funding schemes BOPTN leading research universities in 2013 showed that the best is to form cylindrical briquettes, coal composition : fiber : adhesive : lime : silica is 100 : 17.5 : 10 : 1 : 1 with the position of the fiber portion with most coal in coal briquettes. Determination of bio -coal briquettes is by measuring the heat generated by each briquette Key words: Teaching materials of Thermochemical, Bio-coal briket, fiber of durian leathers
