In recent, raw material such as sodium hydroxide and peroxide is very expencive so that need to look for substitute raw material is ash and chitosan. They are obtained from waste of schrimp processing and wood waste. This research aimed to increase quality and efficiency of paper agar-agar production with method exchanging sodium hydroxide with ash. The result of research show that treatment of ash 30% and chitosan 0.6% can produce gel strength is higher than control (sodium hidroxyde). In general of the reseach shows significancy in organoleptic, gel strength, sulfate, dietary fiber, and rendement but in proxcimate test is not significant. In statistic test (multiple comporison) show that treatment of ash 30% and chitosan 0.6% produce colour and texture of paper agar-agar is the same with control. The treatment increase gel strength (360 g/cm 2)and decrease sulfate (7,69%).
