This research was aimed to utilize the liquid waste of cacao industry as raw material fornata production. Research was performed in two steps : the first steps was clarification processusing active charcoal in different waste dilllutions and the second step was the production ofnata. Result of first step showed that active charcoal concentration and dilution treatmentshowed their effect of all parameters studied. The best result was obtained by treatment of 5%active charcoal concentration and the dilllution of cacao waste : water in 1:3 ratio. The productionof nata in the second step of research was performed using this optimal clarificationcondition. Data showed that the combination treatment of 4% sucrose concentration and 0,4%of (NH4)2SO4 was elected as the best process that gave the best quality of nata. The best treatmentshowed product characteristic : 83,87% of fermentation yield; 95,23% of moisture content;4,22% of fiber content; brightness (L*) of 42,87; 0,01 mm/g.dt of textur and 2,42 cm of natathickness.
