Abstract

Robusta coffee is one of the plantation commodities that has an important role in economic activities in Indonesia. Coffee is one of Indonesia's export commodities which is quite important as a foreign exchange earner for the country. Indonesia is listed as the fourth largest coffee producer after Brazil, Vietnam and Colombia. However, in the export market, Indonesia's coffee is still in ninth place. Post-harvest handling of coffee at the farm level generally produces low-quality, random coffee. Therefore, it really needs to be improved in quality to increase competitiveness in the international market. One alternative that is seen as effective is the improvement of the processing process to produce robusta coffee into fine robusta coffee. This study aims to determine the best yeast starter concentration and determine the best fermentation time to produce specialty coffee in the form of fine robusta coffee. This study used two factors, namely yeast concentration using Saccharomyces cerevisiae which included three levels (2%; 3%; 4%) and fermentation time with 3 levels namely 8, 10 and 12 hours. Repetition is carried out three times. The response variables observed were pH and temperature during fermentation, percentage of unpeeled beans, physical quality of rice coffee, density of kamba coffee rice, increase in roast volume, and taste quality. Data were analyzed using Analysis of Variance (ANOVA) with a confidence level of 5% if the ANOVA results showed a significant difference, followed by the Duncan Multiple Range Test (DMRT). The best results were in the R3F3 treatment (4% concentration and 12 hours time) which could produce coffee with the specialty/fine robusta flavor category. Yeast concentration has a significant effect on pH and temperature after fermentation. Meanwhile, the duration of fermentation has a significant effect on pH and temperature and the percentage of seeds that are not peeled. The results of the organoleptic test of the concentration of yeast and the duration of fermentation had a significant effect on the brewing of coffee and the panelists liked it.

Abstract

Purwoceng (Pimpinella Alpina Molk.) is a native plant of Indonesia. This plant contains potential antioxidants in the form of alkaloids, glycosides, coumarins, triterpenoids-steroids, and saponins. These bioactive compounds are useful as aphrodisiacs, diuretics, and tonics (capable of increasing the body's immune system). Purwoceng-based functional drinks will go through a drying process. This process will result in a decrease in antioxidants in purwoceng. To reduce the loss of antioxidants contained in purwoceng, proper drying is the main key in producing purwoceng-based functional beverage products. The aims of this study were: (1) to determine the characteristics and antioxidant activity of purwoceng during drying to produce functional drinks to increase the body's immune system. and (2) obtaining a drying formula for dried purwoceng products to produce functional drinks to increase the body's immune system. This research method is experimental. This research was divided into four stages, namely: (1) determination of the formulation temperature for drying purwoceng, (2) physico-chemical testing after drying, (3) reducing the dimensions of dried purwoceng, and (4) physico-chemical testing after changing the dimensions of dried purwoceng. . The experimental design used in this study was a factorial Completely Randomized Design (CRD) with 2 factors. The first factor is the drying temperature of purwoceng, while the second factor is whole and counting. Both factors consist of 3 levels with 3 replications so that there are a total of 27 experimental combination units. Observational data were analyzed by analysis of variance (F test) and if they were significantly different, it was continued with the DMRT test at an accuracy level of 5%. The results showed that the best moisture content was the water content of dry purwoceng drying with the lowest value at a temperature of 70? (T4) with a value of whole pieces (P0) 27.95 and chopped pieces (P1) with a value of 26.53. The best pH for drying purwoceng tea is at a temperature of 70? (T4) with whole pieces (P0) getting a value of 6.85, while chopped pieces (P1) get a value of 6.77. The best yield in purwoceng drying is the least yield at 70? (T4). The best antioxidant test results are those that have the highest value at a temperature of 70? (T4). The best test for phenol content is with the highest value at a temperature of 70 (T4). The organoleptic test on dried purwoceng steeping with crystalline coconut sugar got the best values, including: color test with a value of 5, fragance test with a value of 5, and taste test with a value of 4.84.
