LIFE CYCLE ASSESSMENT (LCA) UNTUK ANALISIS ENERGI PADA PROSES PENGOLAHAN TEH HITAM (Camellia sinesis) (Studi Kasus di PT. Perkebunan Tambi, Wonosobo)

Abstract

Tea (Camelia sinensis. L) is one of agriculture�s productions from plantation sub sector that is benefit creator to the country. In tea production process, efficiency aspect of the use of energy can�t be separated from each production, because agro industry especially tea processing industry is a business that must be beneficial so it can be advanced. Energy audit is a beginning step of efficiency and energy conservation actions. Energy audit can help giving perspective of energy using in a production process and identification of energy extravagance. This research aims to analyze the use of energy and material in black tea production process, analyze recycling gas emission and produced garbage, and analyze potential effect to the environment. This research is a case study form as an effort to apply Life Cycle Assessment (LCA) in black tea processing company in PT. Tambi UP Tambi Wonosobo. This research is limited on processing aspects that is from the process of wilting until packing. The result of this research shows that based on its production process, largest energy consumption of tea processing is needed for wilting process while smallest energy consumption is in packing process. To produce 1 kg of dry tea, it needs energy of 7,66 MJ/kg dry tea, where 86,33 % is from electricity, 10,91 is from oil fuel, and 1,94 % is from firewood, and 0,81 % is from human energy. From the analysis result to its emission, firewood is a primary fuel for wilting process and drying gives highest emission. The achieved emission has potential more in glass house effect rather than the effect if Acidification and Eutrophication
