Penentuan Laju Penurunan Kadar Air Opak Singkong Dengan Menggunakan Ruang Pengering Berenergi Biomassa Limbah Pelepah Kelapa Sawit
The research was conducted to determine the rate of decline in water level of cassava opaque by using biomass energy from palm fronds. Drying is done by using a drying chamber with a length of 130 cm, width 90 cm and high 120 cm. The drying chamber is formed in such a manner that is equipped with a chimney, two-level drying rack and 2 drums as heat sources. Drying heat sources derived from biomass combustion of palm midrib in the drum. The room walls are made of plywood with thickness of 8 mm and coated zinc plate with a thickness of 1 mm which is painted black. Samples which were dried were cassava opaque and produced in Rejosari Urban Village, Tenayan Raya District, Pekanbaru. First mass each cassava opaque in the rack 1 at 44.13 grams, 41.99 grams, and 46.27 grams, while in the rack 2 of 47.66 grams, 45.02 grams and 45.98 grams. Drying is carried out for 100 minutes with 10 minute intervals where the room temperature is set about 50 ° C to 65 ° C. The decline in the water content on average on both a rack every 10 minutes for observation 100 minutes are 15.30%, 10.62%, 8.84%, 7.17%, 6.40%, 5.78%, 4.71%, 3.74%, 2.75%, 2.52%.
