Popis:	Cow bone is one type of solid waste that has not been utilized. This waste materials, contains a lot of calcium phosphate. When reacted with sulfuric acid it will form calcium sulfate. The research aimed to find the speed constant value of calcium sulfate formation reaction from cow bone powder with batch sulfuric acid. A 200 mesh cow bone powder is dissolved in water to form a saturated solution. This saturated solution was taken as much as 500 ml then reacted with 4 N sulfuric acid as much as 100 ml, stirred with stirring speed of 200 rpm, with temperature and time according to the variable being run. After reaching the studied condition, the filtrate is separated by its sediment. The precipitate was analyzed for the content of calcium sulfate. The variables studied in this study were reaction temperature (65°C. 75°C, 85°C, 95°C, and 105°C) and reaction time (15, 25, 35, 45, 55 and 65 minutes). The results showed that the reaction follows a pseudo first order reaction, obtained by the equation k = 3.09 e -9735.5/T.
