Rubber seed (Hevea brasiliensis) contains protein (17.41 %) and non-essential amino acid cysteine (0.78 %) and acid cyanide poison (186.00 mg/kg). The purpose of this research was to determine the effect of rice husk ash on degradation of acid cyanide in rubber seed. This research used Completely Randomized Design (CRD) using treatment of rice husk ash concentration with 5 levels of treatments (45; 60; 75; 90; 105 %) and 4 replications. The result showed nonsignificant differences (p>0.05) in degradation of acid cyanide level during aging and significant differences (p<0.05) during soaking. Rubber seed treated with 90% of rice husk ash during aging period contained cyanide 47.25 ppm and rubber seed treated with 60% of rice husk ash during soaking period contained cyanide 40.37 ppm.
