Pra Rancangan Pabrik Pembuatan Bio-Char dengan Bahan Baku Kulit Durian melalui Proses Pirolisis Lambat dengan Kapasitas Produksi 27.800 Ton/Tahun dan Tugas Khusus Rancangan Keteknikan Detail Knock Out Drum

Abstract

Bio-char is a solid product of biomass pyrolysis, which is one of the available technologies for bioenergy production. Bio-char can be used as fuel in the form of briquettes and alternatively as activated carbon and as a substitute for coal. One example of biomass that can be used as bio-char is durian peel, because it has high calorie energy, namely 6,274.9 cal/gr and adequate raw materials. It is hoped that the establishment of this bio-char factory will be able to meet bioenergy needs in Indonesia. Pre-Design Bio-char Factory from durian peel is planned to operate with a production capacity of 27,800 tons/year with 330 working days a year. The planned form of business entity is a Limited Liability Company (PT) with a workforce of 204 people. The results of the economic aspect analysis obtained are as follows:  Total Investment Capital = Rp. 410.055.575.021,07  Total Fixed Costs = Rp. 91.196.760.299,85  Total Sales Results = Rp. 398.661.486.135,56  Gross Profit = Rp 115.481.946.300,77  Net Profit = Rp.80.892.362.410,54  Profit Margin = 28,97%  Break Even Point = 42,86%  Return on Investment = 19,73%  Pay Out Time = 5 Year  Return on Network = 32,88%  Internal Rate of Return = 49,67% Based on the results of the analysis of economic aspects, it can be concluded that "The Pre-Design Factory for Making Bio-Char with Durian Peel Raw Materials Using a Slow Pyrolysis Process with a Production Capacity of 27,800 Tons/Year is feasible to be established.
