Rice husk is high fiber agricultural wastes and with CaCl 2 impregnated, it would be potential to develop as a composite moisture absorber. In this case, the rice husk – CaCl 2 composite can absorb and control the moisture in headspace of packaging to stabilize the water activity of the product. This study was aimed to develop moisture absorber from rice husk – CaCl 2 and apply the sachet of moisture absorber into the package of coconut palm sugar granule (CSG). Moisture absorber was prepared by impregnated the surface of modified rice husk using sodium hydroxide (5% w/v) and CaCl 2 with the concentration of 5, 10 and 15 % w/v. Physical parameters of CSG were analyzed. Rice husk – CaCl 2 15% has the highest moisture absorption. Meanwhile, the using of rice husk - CaCl 2 as moisture absorber was able to maintain the moisture content of CSG during storage at the condition as about 2% with RH 70%.
