SHELLA KHAIRUNISA: Test of Various Size Hole sieve of Dry Cow Bone Miller, supervised by LUKMAN ADLIN HARAHAP and SAIPUL BAHRI DAULAY. The esixtance of livestock waste bone in Indonesia is high enough due to high consumption of livestock meat. The amount of bone waste can pollute the environment if not addressed further. One of the usage waste bone is processed into bone powder. Bone powder produced with the way milled usage bone miler. The aim of this research are to test effect of size sieve hole of dry cow bone miller on water content of bone powder, yield, material losses and the fineness of bone powder. The results showed that the lowest water content of bone powder was at size of hole sieve 250 Mesh that is 0,203 %, the highest yield was at size of hole sieve 150 Mesh that is 96,667 %, the lowest material losses was at size of hole sieve 150 Mesh that is 2 % and the highest fineness of bone powder was at of hole sieve 200 Mesh that is 52,767 %.
