| dc.description.abstract | Animal fat generally have low economic value and less utilization. Animal fat can be processed into tallow through rendering process to produce a raw material in soap making. The purpose of this research was to analyze physical properties of soap by using tallow with milk or cream addition as raw material. The observed variables in this research were water content, hardness, pH, and foaming height. The randomized complete design with 4 treatments and 1 control was used as experimental design. Data were analyzed by analysis of variance (ANOVA). Kruskal Wallis test were used for nonparametric data. The results showed that water content of cream tallow soap and milk tallow soap had significant difference (P<0.05) with control soap. Hardness and foaming height of soap between treatments soaps and control soap had no significant difference. The value of pH of milk tallow soap had significant difference (P<0.05) with cream tallow soap and control. The organoleptic test results showed that cream tallow soap had significant difference (P<0.05) in colour with milk tallow soap. The cream tallow soap had no significant difference of favour with milk tallow soap. There was no significant difference on foaming ability between cream tallow soap and milk tallow soap. | en |
