ABSTRACT

Rhizopus oligosporus isolate have the protease enzyme. This isolate is easily to find in the market in the form of termpeh starter and cheap so it can be used as an alternative to the commercial bating agent that are expensife and not environmentally friendly. The aim of the research is to know the effect of Rhizopus oligosphorus as bating agent to the quality of leather and to find the best concentration and duration of bating from tempeh starter as bating agent. The material used in this research were Nila (Oreochromis niloticus) skin and isolate of Rhizopus oligosphorus from commercial tempeh starter RAPRIMA. The research method used was experimental field. Analysis data in this research used an completely randomized factorial experimental design. Factor A (concentrations of isolate Rhizopus oligosphorus: 0,5%; 1%; 1,5%; 2%; and 2,5%) and factor B (duration of bating : 30 minute, 60 minute and 90 minute). The parameter tested in this reseacrh are soluble protein from bating waste, chrome content, ash content, tensile strength, % elongation, tearing strength, and shrinkage temperature. Based on the result, the value of soluble protein from bating waste 0,28 – 1,08%; chrome content 2,19 – 2,43%; ash content 4,38% – 4,95%; tensile strength 1647,43 – 2161,93 N/cm²; % elongation 90,36 – 109,11%; tearing strength 297,94 – 472,85 N/cm; and shrinkage temperature 98,33 – 101 ⁰C. The results of the research showed that concentration of Rhizopus oligosphorus, had significantly (P<0.05) for soluble protein from bating waste, chrome content, ash content, tensile strength, % elongation, tearing strength, and shrinkage temperature. Meanwhile duration of bating factor had significantly (P<0.05) for soluble protein from bating waste, chrome content, ash content, tensile strength, % elongation, tearing strength, and shrinkage temperature. Interaction of each factor had significantly (P<0.05) for soluble protein from bating waste, chrome content, tensile strength, and tearing strength. Concentration of Rhizopus oligosphorus 2,0% with duration 90 minute was the best treatment with shrinkage temperature (101⁰C), soluble protein content (0,88%) and fulfilled the quality criteria tensile strength (2161,93 N/cm²), tearing strength (441,31 N/cm) for Fresh Water Snake Leather (SNI 06-4586-1998). However not fulfilled in elongation at break (92,73%),chrome content (2,36%) and ash content (4,84%).
