Abstract

Robusta coffee has a higher caffeine content than Arabica coffee. Coffee farmers in Bantaeng, South Sulawesi, do more post-harvest processing using the dry processing method or a natural process where the coffee that has been picked is immediately dried without removing the mucus first by fermentation, fermentation can reduce the content caffeine in coffee. Excessive caffeine in coffee can be harmful to health. The research aims to determine the effect of fermentation time on the quality of Robusta coffee beans and the decrease in caffeine levels. The research method used an experimental method with a completely randomized design (CRD) to determine the effect of natural fermentation time on the caffeine content of robusta coffee beans from Bantaeng district for 0.24, 48 and 72 hours. Data collection was carried out by testing the total microbes in the fermented liquid (total plate count, total bacteria, yeast count, and total lactic acid bacteria), pH, total titrated acid, water content, and caffeine content. The results of the analysis show that the duration of fermentation affects the decrease in caffeine content in Robusta coffee beans. The best treatment in this study was 48 hours of fermentation which had a caffeine content of 2.65%

Abstract

This study aims to analyze the effect of using crude extracts (clove leaves, lemongrass stems and basil leaves) in the immoltilization process of carp seeds in wet transportation. The research method used was a completely randomized design (CRD) with 4 tretments and 3 replication for each treatment. The variables observed in this study were fish induction time, fish sedative time, survival and water quality parameters (temperature, DO and pH). Data were processed using the SPSS program with Analysis (ANOVA) and Kruskal-Wallis. The results showed that the administration of crude extracts (clove leaves, lemongrass stems and basil leaves) had a significant effect on the process of immoltilization of carp seeds on wet transportation with the best treatment of basil crude extracts with 87% survival rate optimal induction time of less than 3 minutes (152 seconds) and optimal sedative time of less than 5 minutes (272 seconds).
