ANALISIS SISTEM PENGERING OPAK SINGKONG TIPE RUANG KABINET DENGAN MENGGUNAKAN BIOMASSA LIMBAH PELEPAH PINANG DAN PELEPAH KELAPA

Abstract

The analysis of cassava opaque using cabinet space of dryer system has been done. The drying chamber was designed with the diameter of 130 cm long, 97 cm width and 120 cm height. This drying chamber was consisted of a drum with height of 70 cm, and diameter of 44 cm. The sample used was cassava opaque that originated from Rejosari Urban Village, Tenayan Raya and Pekanbaru City. Maximum temperature of the drying chamber was 65°C and 69°C for areca midrib and coconut midrib respectively. This was caused biomass energy which generated by coconut midrib waste greater than that produced by areca midrib waste. The average water content of cassava opaque obtained in this research using biomass waste of areca midrib was 15.98%, 12.97%, 11.56%, 9.38%, 7.21% and 6.07%, while the average water content for cassava opaque using biomass waste of coconut midrib was 24.29%, 12.21%, 11.16%, 8.43%, 6.48% and 5.20%. Efficiency of the drying time using biomass waste of areca midrib was 96.01% while the efficiency of the drying time using biomass waste of coconut midrib was 97.13%.
