Abstract

PT. X has conducted a Life Cycle Assessment (LCA) study in 2019. However, it has not been proven that the air emission reduction program that has been implemented is effective in reducing the environmental impacts that occur. In this study, the LCA study is continued to identify the largest environmental impacts that occur and hotspot units after implementing the air emission reduction program and determine the effectiveness of the program. SimaPro software was used to conduct the LCA analysis, with a midpoint approach and using the CML-IA Baseline method. Based on the LCA analysis, the biggest environmental impacts that occur at PT X are acidification in SP A, B, C and global warming (GWP100a) in SP D. the air emission reduction program that has been implemented since 2019 has effectively reduced the impacts that occur. The recommended improvements to reduce the impact of acidification and global warming are replacing diesel engines with gas engines, installing Non-Selective Catalytic Reduction (NCSR), utilizing flare gas into compresses natural gas, and enhancing oil recovery using carbon capture separation technology to capture CO2 gas.

Abstract

The largest emission from the petroleum production process is dominated by nitrogen oxide (NOx) gas which accounts for 60% of the total emissions. In this research, an assessment of the impacts that occur from petroleum production activities is carried out using the Life Cycle Assessment (LCA) method. In this study, the identification of environmental impacts was carried out using the SimaPro 9 application software and the midpoint-based assessment. In the midpoint assessment, 1 method is used, namely the CML-IA Baseline method. Life cycle impact assessment (LCIA) or impact assessment using midpoint assessment includes global warming, human toxicity, photochemichal oxidation, ozone layer depletion, acidification, eutrophication, abiotic depletion, and abiotic depletion (fossil fuel). Emissions analyzed include CO2, CH4, NOx and SOx. In this study, the scope of analysis used from the process system is cradle to gate. The results of the analysis resulted in the greatest impact value coming from unit A power generator. The largest impact category from the CML-IA Baseline method is acidification. The results of the sensitivity check analysis resulted in the value of both variations above 10%, namely 16% of each variation. The recommended alternative program scenario is cogeneration technology and nonselective catalytic reduction (NSCR) because it can reduce acidification by 69.81%, eutrophication 69.82% and human toxicity 69.40%.

Abstract

Climate change is a global issue that affects various sectors, including the electricity sector, with one of the impacts of climate change being the increased risk of landslides influenced by rainfall, land use, slope gradient, and soil type. This research aims to assess the landslide risk in East Kalimantan on electricity infrastructure and formulate adaptation strategies for these landslides. The research method is a quantitative analysis and spatial approach by combining historical data and climate projections up to the year 2060 using the CMIP6 dataset scenarios SSP2-4.5 and SSP5-8.5. Data processed using Geographic Information System (GIS) to produce landslide risk maps for both current conditions and projections. The determination of adaptation strategies is carried out through a combination of SWOT Analysis and Analytical Hierarchy Process (AHP) methods. This research shows that the projection of landslide risk class areas in most parts of East Kalimantan is predominantly in the moderate risk class with an area of 58.16% and the high-risk class with an area of 26.43%. The priority strategies for landslide adaptation in the development of electrical infrastructure are chosen based on the analysis of three aspects: the optimization of DPT development and other supporting technologies in a planned and integrated manner, the preparation of a roadmap for prioritizing the reduction of extreme operational risk points as part of efforts to adapt to the projected increase in landslide risk, and the utilization of evaluation results from periodic monitoring and field inspections to support risk-based electrical infrastructure development planning.

Abstract

Stunting is a serious nutritional problem that requires immediate attention. In Malaka Regency, East Nusa Tenggara Province, the prevalence of stunting remains high due to poor sanitation and ineffective organic waste management. This community service program aims to increase public awareness and skills in utilizing organic waste to produce eco-enzyme and its derivatives, such as eco-enzyme-based liquid soap. The program was conducted from July to November 2025, involving 33 participants representing local government, community leaders, and informal community figures. The activity explained the relationship between sanitation and stunting through discussions and demonstrations on producing eco-enzyme from household organic waste. Evaluation through pre- and post-tests showed a significant increase in participants’ knowledge of sanitation, stunting, and organic waste management. Community-based education on eco-enzyme has proven to support food security and environmental health while contributing to reducing the risk of stunting.
