<![CDATA[PT Minarak Gas Brantas Inc.'s operations in the Wunut Field involve the production of waste in various forms, primarily liquid waste, with produced water being the most significant type. Proper management of this produced water waste is crucial to prevent environmental pollution and ensure economic and environmental sustainability. The company manages this waste by reinjecting it into the reservoir to prevent groundwater contamination. To ensure the effectiveness of this reinjection process, they have created a groundwater flow pattern map (flow net) at three locations near the injection well: LP1 in Keduung Boto Village, LP2 in Candi Pari Village, and LP3 in Candi Pari Village, all in Sidoarjo Regency. This helps in understanding the potential spread of pollutants in the soil and underground water, aiding in environmental pollution monitoring and managment.The groundwater from this area is used for various human activities like bathing, cooking, and washing. However, based on water quality standards outlined in Ministry of Health Regulation No. 2 of 2023, the produced water from Well X-1 in the Wunut Field does not meet the required TDS (Total Dissolved Solids) content standards due to a decline in hydrocarbon fluid production, resulting in a separator efficiency of 74,86%. Additionally, lab tests and flow net results indicate that the TDS levels in LP1, LP2, and LP3 do not meet the sanitation and hygiene water quality standards, suggesting potential seepage in these locations that could contaminate groundwater. Keywords: Oil; Gas Produced Water; Gas Separator Eficiency; Groundwater Flow]]>

This research aims to determine the effect of a mixture of organic materials, fruit and vegetable waste eco enzyme on pH, and the effect of eco enzyme dosage on improving the water quality of Lake Batur, Kintamani Bali. Making eco enzymes using vegetable and fruit waste. water, molasses in a ratio of 3: 10: 1. The liquid is fermented for 3 months while observing the fermentation process. Eco enzyme is harvested and filtered, ready for testing to improve the water quality of Lake Batur. The results of observations of making eco enzyme can be explained that in the first 4 weeks, there was a change in colour with shades of brown to reddish, after the fourth week the colour was relatively stable (no colour change. Changes in pH during the process of making eco enzymes were related to variations in the composition of organic material (vegetable residues. There was a decrease in pH). with an average of up to 1 digit, the highest reduction occurred in ingredients containing papaya, mango and mustard greens. Eco enzymes can improve water quality as indicated by several water quality parameters, but are not enough to achieve conformity with the established quality standards.

<![CDATA[The high perception of Kawah Putih Ecotourism management in involving the community in economic activities still has no impact on increasing people's income and standard of living, so it is necessary to analyze the impact of Kawah Putih Ecotourism development on the socio-economy and environment of the surrounding community and its development strategy. First, it is measured with ecotourism parameters for implementation to determine the economic impact on society which is analyzed with income inequality and Klassen typology. Social impact analyzes its positive and negative impacts. The physical environment is analyzed through environmental awareness parameters and development strategies using IFE-EFE, SWOT and QSPM techniques. The results of the research evaluating the application of the principles and criteria of Crater Ecotourism obtained quite high performance results. While the economic analysis of the average per capita income of the community is relatively small for economic growth, the classification of the Klassen typology of the Kawah Putih community is still considered a disadvantaged area. The social impact of the community is categorized as moderate with a slightly larger percentage of negative impact. The level of environmental awareness is still felt to be quite high. Kawah Putih ecotourism priority strategy is to implement quality and licensed management and services by prioritizing honesty, hospitality, comfort and cleanliness to create tourist loyalty so as to improve the economy, social community is more inclined to positive impacts with high environmental awareness.

<![CDATA[This research aims to analyze the best scenario for conserving Lake Batur, Batur UNESCO Global Geopark (BUGG), Bali. Using the system dynamics method, key factors in the management of Lake Batur can be identified. Based on modeling results, it is known that the sustainability of Lake Batur is strongly influenced by aspects of land use, the environment, the economy, and the social culture of the community. The main leverage factors in supporting the preservation of Lake Batur are law enforcement and supervision, government assistance, as well as training and outreach to the community. The analysis of the sensitivity value of the optimistic/moderate ratio shows that the optimistic scenario is the best option to reduce the lake pollution index to 0.86 (still below the 1 threshold). Increasing community income per capita in this area in 2045 is estimated to reach Rp87.992.747,76/year, with predictions of 9,312 floating net cage plots owned by 2,592 entrepreneurs. The predicted number of plots is 14.90 ha, which is still below 1% of the area of Lake Batur. Keywords: System Dynamics; Sustainability; Lake Batur; BUGG]]>

<![CDATA[Ecosystem services are the benefits that humans obtain from ecosystems. With the growing demand to implement sustainable development, the need for information on ecosystem services is increasing as a consideration in various policies and development planning. In response to this need, the method that is often used is the preparation of ecosystem services maps using an approach obtained from land cover data. Many people think this method works well and saves a lot of time and money, especially for studying places on a global, regional, or national level, where it's easy to get data on land cover. The point of this study is to look at how the results of the 2018 and 2022 food supply ecosystem services maps compare. These maps were made by experts who thought about how ecosystem services could be used in different types of land and ecoregions. The Analytical Hierarchy Process (AHP) with the pairwise comparison method is used to figure out how much ecosystem services are worth in relation to land cover and ecoregions. The island of Bali was used as a study area, and food supply was the type of ecosystem service that was looked at. Ecoregion data results for 2022 with the high class being more dominant and having an area of 385,339.19 ha or the equivalent of 66.67%. Land cover in 2018 produced a dominant high class with an area of 288,931.82 ha or the equivalent of 48.74%. The land cover results in 2022 are predominantly high class with an area of 289,039.25 ha or the equivalent of 50.01% of the total area of the island of Bali. The analysis results from the combination of ecoregion and land cover in 2022 are predominantly high class with an area of 182,039.65 ha or the equivalent of 31.49%. Several factors can explain the connection between ecosystem processes and the benefits they provide, which can get around or lessen the problems with using land cover data. Keywords: Ecosystem Services; Expert Judgement; Ecoregion; Land Use Based Proxy]]>
