Abstract

Organic robusta coffee cultivation in Klungkung Village can cause environmental pollution and has the potential to produce greenhouse gases (GHG) due to inefficient use of energy. Upstream processes or gardens use organic fertilizers without proper knowledge. Meanwhile, downstream or processing uses technology and produces waste that is not yet environmentally friendly. This study aims to determine how much impact the processing of organic robusta coffee can make, so that the product can be said to be feasible as an environmentally friendly product. The method used in this research is Life Cycle Assessment (LCA) which has stages of determining goals and scope, life cycle inventory, life cycle impact assessment and interpretation. Processing of organic robusta coffee products produces a GWP of 21,2768 kg CO2-eq and the efficiency of energy use shows a NER value of 0.02 and a NEV of -153.94. The recommended alternative improvement is the use of coffee horn skin which is processed into briquettes as a substitute for LPG fuel in the roasting process. If the alternative recommendations are implemented, it can reduce the GWP value to 20.4374 kg CO2-eq and increase energy use efficiency to a NER value of 1.09 and NEV of 9.86. The environmental impact resulting from this research is the amount of greenhouse gases (GHG) resulting from the organic robusta coffee production process, if not repaired, it will pollute the surrounding environment.

Abstract

Wastewater production from the coffee agroindustry is generally brown. Melanoidin contents cause it and the high content of organic matter in coffee processing wastewater can impact water pollution. Turbid coffee processing wastewater can prevent sunlight from entering the water if it is channeled directly into water bodies without prior treatment. The research aims to improve the quality of coffee processing wastewater using the photo Fenton method, which combines catalyst reagents from H2O2 and FeSO4. The stages of the research consist of adjusting the pH of the process, combining H2O2 and FeSO4 dosages, irradiating using UV light, settling, and analyzing wastewater quality improvements with parameters i.e. Total Suspended Solid (TSS), turbidity, color, pH, and Chemicals Oxygen Demand (COD). The research results show that adding H2O2 and FeSO4 treatment in the Fenton photo can improve the quality of coffee processing wastewater. H2F1 treatment (H2O2 0.2 M and FeSO4 0.0015 M) is the best alternative for reducing TSS, turbidity, color, and COD parameters. The percentage reduction values for TSS, turbidity, color, and COD is sequentially 95.55; 98.40; 93.97; and 72.47 %. The combination of H2SO4 and FeSO4 catalysts can be used as an alternative tertiary method for coffee agro-industrial wastewater purification which is effective and efficient.
