Charcoal is a coconut derivative product produced from burning coconut shells. In this study, coconut shell charcoal was obtained from the by-product of copra processing. The processing of coconut shell charcoal produces emissions that pollute the environment, which are greenhouse gas (GHG) emissions equivalent to CO2eq. Life cycle assessment (LCA) is a method that can assess the environmental impact of a product throughout its life cycle. Net energy calculation was carried out to determine the energy efficiency of charcoal production in the form of net energy value (NEV) and net energy ratio (NER). The LCA studied was gate-to-gate, namely from coconut shell transportation to processing into charcoal with emission function units per 1 kg of coconut shell charcoal product. The study was conducted at CV X, located in Sukabumi, West Java, Indonesia. The calculation results show that the raw material transportation stage produced 0.0626 kg CO2-eq/kg charcoal, while the pyrolysis stage produced 0.212 kg CO2-eq/kg charcoal. Energy efficiency analysis showed NEV 9,398.66 MJ and NER 1.09. Recommendations for improvement that can be given are to produce charcoal in one place with a copra factory and produce liquid smoke from the combustion of charcoal. Charcoal production in one factory with a copra factory could reduce the GHG impact by 48%, increase NEV to 12,823.19 MJ, and increase NER to 1.13. Utilization of smoke into liquid smoke increased NEV and NEV to 107,715.75 MJ and 2.03. Combining the two scenarios increased NEV and NER to 211,856.62 MJ and 2.10.

Indonesia is a country with the largest number of tempeh producers in the world. However, the practice of tempeh production by most entrepreneurs has not paid enough attention to environmental aspects. In this study, Life Cycle Assessment (LCA) was used as a method to assess the environmental impact of tempeh labeled as hygienic, produced by Rumah Tempeh Indonesia (RTI) located in Bogor, West Java. The hygienic tempeh consists of two types, namely one made of local soybean (Tempeh Sehat) and the other made of imported soybean (Tempeh Kita). The extent of the environmental impact, in the form of GHG emissions and energy efficiency, throughout the life cycle of tempeh is calculated, analyzed and some improvement scenarios are proposed. The life cycle of tempeh is limited to soybean cultivation, raw material transportation and tempeh processing at RTI. The results show that Tempeh Sehat generates GHG emissions of 0.323 kg CO2-eq, while Tempeh Kita is 0.555 kg CO2-eq per kg of product. The hotspots that contribute to GHG impacts are identified as originating from the stages of soybeans transportation and tempeh processing. Energy efficiency is indicated by the Net Energy Value (NEV) and the Net Energy Ratio (NER) of both types of products. Tempeh Sehat has NEV of 2.064 MJ, while Tempeh Kita is 0.318 MJ. Both types of products show the value of NER>1. Further analysis of existing production practices has led to several scenarios of improvement and their environmental effects have been discussed. Keywords: Tempeh; LCA; GHG emission; energy efficiency
