Comparison of Drying Temperature and Three Types of Coffee Beans on Physical Quality
Taufiq Ramadhan | Antar Sofyan [2] | Akhmad Gazali [5]
Abstract: South Kalimantan is one of the provinces that develops local coffee which is carried out by coffee activists together with indigenous communities and farmer groups. The types of coffee that dominate in South Kalimantan are robusta coffee (village coffee), liberica (wood coffee), and excelsa (yellow coffee) which are cultivated in lowlands such as peatlands and tidal swamps. Based on the results of observations made in the field, several causes are the low selling price of coffee beans on the market because the post-harvest process is not managed well and according to standards to improve the quality of coffee. The aim of the research was to determine the treatment response of different drying temperatures and three types of coffee beans to physical quality and to find out the combination of treatment comparisons of drying temperatures and three types of coffee beans to physical quality which was close to the SNI quality value of coffee beans. This research used a two-factor Randomized Block Design (RAK). The factors studied were drying temperature (S) for 3 treatments and coffee bean type treatment (J) for 3 experimental treatments consisting of 9 combinations and each treatment was repeated 3 times so that the total experiment was 27 experimental units, consisting of S1: Drying temperature 80 oC, S2: Drying temperature 90 oC, S3: Drying temperature 100 oC, J1: Liberica coffee, J2: Robusta coffee, J3: Excelsa coffee. The treatment of different drying temperatures and three types of coffee beans provides a response to the parameters, namely, water content, number of bean defects, color and size compared to the quality value of SNI 01-2907-2008. The combination of treatments that provide a response close to the quality value of SNI 01-2907-2008 is, the wet base water content is the Robusta treatment with a temperature of 90 oC, the defective coffee beans are the Liberica coffee type and the temperature is 100 oC, the color of the coffee beans is robusta and excelsa, while for temperatures of 80 oC and 90 oC, the size of the coffee beans is liberica with a temperature of 80-90 oC.
