Parameters observed were were water content, yield and chips organoleptic test (taste, crunchness, and total acceptance). The results showed that the highest yield was K2 39,509% and the lowest was K1 23,512%, the highest water content was K1 2,715% and the lowest was K2 2,454%, while the highest organoleptic taste was K1 3,600 and the lowest was K2 and K3 3,167, the highest crunchness was K1 3,700 and the lowest was K3 3,500, the highest total acceptance was K1 3,477 and the lowest was K3 3,230.
