ANALISIS TEKNIS DAN EKONOMIS PADA PENGERINGAN GULA SEMUT MENGGUNAKAN CABINET DRYER

Abstract

Drying is the process of reducing moisture content in material so the material has a longer shelf life. Drying of brown sugar are still mostly done using the sun, despite the dryer. However, using of the dryer is still limited because the public perceives that the dryer uses less efficient due to higher operating expenses. Therefore technical and economical analysis of the brown sugar dried with cabinet dryer. Drying process of brown sugar done with 3 variations of temperature are 60oC, 70oC,80oC and 3 variations of capacity are 5kg, 10kg, and 15kg. Data taken include changes in temperature, moisture content, fuel and electricity that used during the drying process. Technical analysis includes the drying constant rate and drying efficiency. While the economical analysis includes break-even point, R / C ratio, payback period, and sensitivity analysis. The results showed that the constant rate of drying of brown sugar with cabinet dryer has a larger value than the drying of brown sugar with sun drying. The highest drying efficiency is drying capacity 15 kg at drying temperature 80oC that was 8,4921% afterwards the variation drying capacity 10 kg at drying temperature 80oC that was 5,7170%. Although the variation of drying capacity 15 kg at drying temperature 80oC has longer BEP (130hari/tahun > 124 hari/tahun), higher R/C Rasio (1,0268 > 1,0264), and longer payback period (1,6 tahun > 1,5 tahun) that compared with capacity 10 kg at drying temperature 80oC, however the variation capacity 15 kg at drying temperature 80oC was more opportune because it has higher drying efficiency compared with capacity 10 kg at drying temperature 80oC. Drying of brown sugar capacity 15 kg at drying temperature 80oC sensitive at higher interest rates more than 55,97%, and sensitive to the decrease in raw material capacity if more than 2,75%
