Pemanfaatan abu gosok dan khitosan sebagai upaya peningkatan mutu dan efisiensi pada pengolahan agar-agar kertas di Pameungpeuk, Garut Jawa Barat

Abstract

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 signiftcancy in organoleptic, gel strength, sulfate, dietary fiber, and rendemen t but in proxcimate test is not significant. In statistic test (multiple wmporiwn) show that treatment of ash 30% and chitosan 0,6% produce colour andtexture of paper agar-agar Is the same with control. The treatment increase gel strength (360 g/cm 2)and decrease sulfate (7,69%),
