BACKGROUND AND OBJECTIVES: The global competitiveness of the cocoa processing industry is enhanced through the implementation of technical policies as a sustainable economic sector. The effort is motivated by the potential of large cocoa production and the international market demands for the industry to apply innovative, effective technology and comply with sustainability standards (environment, social, and economic). Therefore, this study aimed to analyze the environmental impact assessment of cocoa production from upstream to downstream processes in North Luwu Regency, South Sulawesi.METHODS: Data were collected from 321 respondents actively working and had at least 8 years of experience in cocoa cultivation and production. Respondents included staff of the Masagena Farmers’ Cooperative from Chalodo Sibali Resoe Industry, Masamba City, and North Luwu Regency, and the secondary data were obtained from a literature review. In addition, the environmental impact was determined using the Midpoint Recipe method and the ecoinvent 3.8 database. This was conducted based on the International Standard Organization of life cycle assessment 14040 and 14044 with a function unit of 1 kilogram chocodate cashew production.FINDINGS: The results showed that reducing chemical fertilizer was environmentally preferable to decreasing all the impact categories assessed since the total potential global warming impact from chocodate cashew production was 2.092 kilogram carbon dioxide equivalent. In this context, electricity and fertilizer were the main contributors to environmental pollution, accounting for 0.438 kilogram carbon dioxide equivalent and 0.215 kilogram carbon dioxide equivalent at 20.97 percent and 10.27 percent, respectively.CONCLUSION: The reduction in the use of inorganic nitrogen, phosphate, potassium fertilizer, from 3.75 to 1.25 kilogram perkilogram cocoa, or the adoption of bio-based nitrogen, phosphate, potassium fertilizer at a rate of 2.5/ kilogram, could substantially mitigate the environmental impact. This mitigation resulted in a 16 percent decrease in global warming potential, reducing from 2.092 to 1.745 kilogram carbon dioxide equivalent. In addition, valuable insights were provided into the scope of life cycle assessment studies and contributed to the selection of sustainable cacao farming systems. These results could be relevant to life cycle assessment practitioners, stakeholders, and governments in offering valuable insights for the formulation of policies and programs for developing cacao farming in the future.

BACKGROUND AND OBJECTIVES: Palm oil mill effluent is a liquid waste produced at a palm oil mill industry during the production process containing abundant organic pollutants such as nitrogen and phosphorus that will be harmful to the environment. However, palm oil mill effluent as a nutrient for the growth of microalgae has the potential for pollutant removal as well as algae biorefinery products such as biofuel, functional food and many others. This research objectives to analyze the sustainability of the microalgae biomass production for bio-refinery based on the sustainability index assessment. METHODS: The primary data was compilated via the questionnaires to researchers in the community of microalgae as well as scientific judgment by experts as respondents. Data is processed and analyzed using the multidimensional scaling Rapfish program. Data analyzed was conducted by analyzing four dimensions: social, economic, ecological, and technological dimensions which consisting of 47 attributes.FINDINGS: The result showed that the sustainability index calculated was 73.53 percent (good), which indicates the process has the potential to be developed while paying attention to leverage factors in every dimension of the sector. Analysis of each dimension on the 4 dimensions shows that the environment dimension is lowest in 67.30 percent, while the economy, technology and social dimension are 70.99 percent, 73.67 percent and 82.17 percent, respectively. Some leverage attributes that require more attention in order to improve sustainability are management experience and skills (in environment dimension), involvement of family member (in the social dimension), the productivity level (in economic dimension), and management of experience and skill (technological dimention).CONCLUSION: Based on the prospective analysis, it is known that there are 4 key factors or dominant factors that are very influential in the microalgae supply system, namely production, productivity, land conversion, consumption per capita and population. It is still necessary to do further research for the utilization of microalgae biomass into value-added products with an optimal, technically, economically, environmentally and socially sustainable system. The study provides insights on the feasibility of the proposed sustainable concept in Indonesia for the government to arrange policies and programs.
