Increased density of rice husk into bio briquettes will increase the calorific value, but the initial firing rate would be longer. One way to shorten the ignition time by adding an oxidant that supply oxygen for the oxidation reaction or adding liquid igniter to the fraction of briquette was called briquette igniter. Oxidizing agents that was used in this research were KMnO4, jatropha seeds and gondorukem. The purpose of this research were to observe the effect on bio briquettes igniter which could be shorten the ignition time and provided a homogeneous rate of combustion, briquetting pressure effects and the influence of composition on combustion characteristics briquettes. Oxidizers were mixed with rice husk that have been torrefied, coal and starch. Mixture then moulded and pressed to form a briquette. Proximate analysis, ultimate and calorific value were the quality parameter of these briquettes. Combustion characteristics were tested with test ignition time and hold time burning to find out the quality of briquettes combustion through the combustion temperature profile testing. Based on these results, the best torrefaction process at temperature 300º C and holding time 10 minutes. The best igniter was jatropha seeds with a short ignition time in the 19th minute and lasting burning time was 29 minutes long. Briquetting pressure of 100 kg/cm2 provided the shortest time that was burning in the 19th minute with a good briquette strength. Composition of rice husk and coal 70% and 30% provide the optimum combustion at ignition time in 19th minute, firing 29 minutes hold time, volatile metter 49.98%, fixed carbon 20.98% and caloric value 3885.7 kcal /kg.

Higher energy needs to be supplied from a wide variety of energy sources, including renewable energy. In connection with the depletion of fossil energy sources and the impact on the environment, the use of energy from renewable energy sources including biomass is increasing. The types of biomass that can be used include oil palm empty fruit bunches, palm shells, palm fruit fiber, rice husk and straw, corn cobs, sugarcane bagasse, etc. The potential of biomass that Indonesia has around 32000 MW and only about 1740 MW or 5.4% utilized [1]. Certainly the opportunities utilization of biomass as an energy source is still wide open. Currently, biomass utilization is still low, the amount of biomass accumulate and give rise to new problems such as decay and produce gases that affect the environment. Biomass can be used as fuel by various processes that direct combustion, gasification or pyrolysis. So far, most utilization of biomass is done by direct combustion in the combustion
