Abstract

The process of making Balinese arak used distillation of coconut palm through a process of heating and re-condensing the heated nira so that it becomes arak with alcohol content. Based on the results of the research the effect of fermentation time on alcohol content in coconut nira (Tuak), fermentation time for 6 hours, 8 hours and 12 hours on alcohol content in coconut nira, with heating temperature of the reactor tube 70°C, temperature 75 °C and temperature 80°C, the length of time for sampling used was 10 minutes, 20 minutes, and 30 minutes, indicated by an increase in the percentage of alcohol content. The average alcohol content of coconut nira in fermentation for 6 hours, heating temperature of 70° C is 38%, fermentation for 8 hours, heating temperature of 70°C is 53%, fermentation for 12 hours, heating temperature of 70°C is 63%, fermentation for 6 hours, heating temperature 75°C is 41%, fermentation for 8 hours, heating temperature 75°C is 55%, fermentation for 12 hours, heating temperature 75°C is 65%, and fermentation for 6 hours, heating temperature 80°C is 45%, fermentation for 8 hours, heating temperature 80 °C is 63%, fermentation for 12 hours, heating temperature 80°C is 70%. Based on the ANOVA test output, a significance probability value of 0.000 can be obtained. Therefore, the significance probability value is 0.000 <0.05, so that the hypothesis is rejected, which means that there is a significant difference in fermentation time for 6 hours, 8 hours and 12 hours on the alcohol content with heating temperature in the reactor tube which is 70°C, 75°C and 80°C and temperature holding time for 10 minutes, 20 minutes and 30 minutes.
