Completely randomized design (CRD) method on lard analysis which was adulterated to palm oil.

Lard which was adulterated into palm oil was extracted by maceration and analyzed for physicochemical properties. Maceration method was developed using n-hexane solvent and analysis of physicochemical properties including: specific gravity, acid number, iodine number and total microbe. The factorial completely randomized design (CRD) method used consisted of two factors, namely: Factor I: Solvent Concentration (K) consists of 4 levels, namely: K1 = 20%, K2 = 30%, K3 = 40% and K4 = 50%, and Factor II: Sample Weight (B) consists of 4 levels, namely: B1 = 10 g, B2 = 20 g, B3 = 30 g and B4 = 40 g So the number of treatment combinations (Tc) is 4 x 4=16 with 2 (two) replications. The results of the RAL method analysis showed that the concentration of n-Hexane gave a very significant difference (p < 0.01) on the specific gravity. Maceration time gave a very significant difference (p < 0.01) on specific gravity. the effect of the concentration of n-Hexane gave a very significant difference (p < 0.01) on the acid number, the effect of the concentration of n-Hexane gave an insignificant different effect (p > 0.05) on the iodine number, the effect of the concentration of n-Hexane gave the effect was not significantly different (p > 0.05) on the total microbe and the effect of maceration time gave a very significant different effect (p < 0.01) on the total microbe.
