Abstract

Virginia tobacco is the largest agro-industry component in West Nusa Tenggara (NTB). The lack of subsidized kerosene quotas for tobacco extraction, even the central government decided that in 2018 the sub-oil kerosene quota will be abolished, brings its own problems. Based on this problem, research was carried out with the title how to characterize castor beans as an alternative fuel to replace kerosene as a substitute for tobacco extraction fuel with the aim of proving that castor beans can be used as an alternative fuel for drying tobacco. process without reducing the quality and economy of tobacco. This research was carried out experimentally. From the research results it can be concluded that castor bean fuel can be used as a fuel substitute for kerosene for tobacco production as proven by the results of the characteristic test, namely the calorific value produced in this research has met the national standard (SNI), namely 5288.844 cal/gr based on the standard. which meets American standards, namely 4000-6500 (Source: Hendra, 1999 in Sunyata and Wulur, 2008). economic value aspect of fuel consumption / 1 kg of dry castor beans consumes 6.7 kg of castor beans at a price of Rp. 6,700 lower than kerosene, LPG and bioethanol. Variable standard drying temperature with a drying rate of 1 m/s produces tobacco compost with the best quality color and aroma.
