Abstract: | Liming is one of the most important processes in beamhouse and has many functions relating to the nature and quality of leather. Concentration of calcium hydroxide and temperature are thought to be a factor affecting the liming process and the quality of leather produced. The objectives of this study were to determine the characteristics of tuna skin, to determine the effect of the concentration of calcium hydroxide and temperature on the liming, and to determine the best treatment of the concentration of calcium hydroxide and temperature on the quality of limed pelt. There were four responses observed, i.e. the protein content, fat content, swelling, and pH. Based on this research, tuna skin had higher level of protein that was high enough to be processed into leather. Treatment of calcium hydroxide concentration did not significantly effect to all responses. Level of 5% calcium hydroxide concentration was the best treatment, as it gave three responses that achieve the best conditions. Temperature treatment showed a significant effect on the responses of fat content and swelling. Specified temperature as the best level was 30 °C, because there were two responses that achieve the best conditions at that level. |
