    Abstract

    To overcome the problem needs an alternative fuel that is then taken for processing combustion water hyacinth water hyacinth into charcoal briquettes. This research aims to study the reaction kinetics of combustion of charcoal briquettes on the basis of accelerated depreciation of water hyacinth water hyacinth charcoal briquettes with various varioabel temperature and time to obtain the constant burning. This research was done by adding a binary solution in the form of starch with a concentration of 20% on charcoal water hyacinth which has a particle size 40 mesh, weighing 30 grams, then pressed and dried. Once dried water hyacinth dirimbang Charcoal briquettes and burned at a temperature of 200 oC, 250 oC, 300 oC, 350 oC and 400 oC until reaching constant weight. The results obtained by the heating value of water hyacinth charcoal briquettes at 5673 cal / garm, 30.002% ash content with 0.0475 MPa compressive strength. Combustion reaction rate constant of water hyacinth briquettes obtained at temperature of 200 ° C is 0.1230, the temperature of 250 ° C is 0.1680, a temperature of 300 ° C is 0.2364, the temperature of 350 ° C is 0.3782, and the temperature of 400 ° C is 0.4804. Frequency factor (Ko) of 0.9401 / h and the activation energy of 4445.9125 cal / mol L Then it can be concluded in this study the reaction takes place on the order of one. Key words: accelerated depreciation of water hyacinth charcoal briquettes, rioabel temperature and time to obtain the constant burning
