ANALISIS TEKNIS DAN EKONOMIS PADA PENGERINGAN GULA SEMUT MENGGUNAKAN CABINET DRYER

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%

Drying is important process in the producing of palm sugar. It carried out to reduce sugar moisture content in order to extend its shelf life. Nowadays, Indonesian palm sugar home industries usually use direct sun drying because of limited information of the effectiveness of mechanical dryer. This research was conducted to analyze cabinet dryer performance to dry palm sugar on various temperature and capacity. There were three different temperature and capacity used in this research. Palm sugar temperature and water content was observed every 10 minutes during drying. Dryer performance was evaluate by determining drying rate and drying efficiency. This result showed that increasing drying temperature from 60 C to 80 C increase drying rate significantly, while increasing drying capacity from 5 kg to 15 kg could not increase the drying rate in a significant value. The highest drying efficiency was 8,49% that belongs to 15 kg on capacity and under 80 C process temperature. The drying rate with cabinet dryer at temperature at least 70 C was higher than those in direct sun drying
