HASIL PLAGIASI FINANCIAL ANALYSIS ON ROTAN INDUSTRIAL WASTE UTILIZATION FOR CEMENT BOARD PRODUCTION

Abstract

Rattan wool waste in rattan carpet industry in South Borneo is approximately 347,256 tons per year. This high amount of waste material will be great potential to be manufactured as a new useful product. The aim of this research was to analyze the possibility of the use of waste material in forest product industry for cement board manufacturing with lime pozzolan cement. The composition between the waste material weight and composition cementing agent was determined based on SNI 03-2104-1991. The economic value of this new product was also considered: B/C Ratio, NPV, IRR dan pay back period. This research resulted in the best ratio of 225 gr rattan wool and lime cement for cement board production was cement 225 gr and lime 150 gr. This ratio meets the cement board manufacturing standard. Besides, this ratio was the most economically cheap in raw material, and alternatively comparable with other similar product in the market. B/C ratio in the discount rate 15 % = 1,082 ( feasible) , the discount rate at 25 % = 1,015 (feasible) and the discount rate at 35 % = 0,956 (unfeasible ). NPV in the discount rate 15 % = + IDR.105.101.568,00 (positive) , the discount rate at 25 % = + IDR.3.978.560,00 (positive) and the discount rate at 35 % = - IDR.10.414.720,00 (negative). Value IRR % = 27,764. Time capital repayment (pay back period) only less more 2 years 7 months
