Climate change and global warming are directly linked to the rise in carbon dioxide (CO2) concentration in the atmosphere, a significant byproduct of various human activities, particularly the combustion of fossil fuels. To regulate Earth's surface temperature within specified limits, the concept of a carbon budget is introduced. This budget represents the maximum cumulative carbon emissions that can be emitted to the atmosphere before the earth’s global temperature exceeds some particular temperature levels. According to the Intergovernmental Panel on Climate Change Assessment Report 6 (IPCC AR6), maintaining a temperature increase within 1,5 to 2°C requires adhering to a global carbon budget (GCB) of approximately 500 to 1.350 GtCO2 (at a 50% likelihood level). To determine the national carbon budget (NCB) for Indonesia, various allocation methods, including egalitarian, grandfathering, weighted average, and per capita convergence approaches, are applied. At a 50% likelihood level to restrict temperature rise to 1.5°C, Indonesia's NCB at the beginning of 2022 falls within the range of 14.28 to 20.55 GtCO2. These values for the carbon budget can serve as a valuable tool for assessing the climate change mitigation targets outlined in Indonesia's enhanced nationally determined contribution (E-NDC).

Tuksono Village is in Sentolo District, Kulon Progo Regency with a population of 8,560 people in 2021 and almost all Tuksono village residents have teak plantations of around 100 hectares. Large teak plantations produce dry teak leaf waste, this is because the adaptation of teak trees in the summer is to shed their leaves. So teak leaf waste is produced every dry season and causes problems for the surrounding environment. With these problems, efforts are needed to process teak leaf waste and based on the composition of teak leaves, it can be processed into compost. In the process of composting teak leaf waste with the addition of cow dung, the C, N and C/N ratios still do not meet SNI 19.7020-2004. This is because teak leaves have a relatively high carbon content, so for the composting process of teak leaves it is not enough to just add cow dung but requires additional materials that can increase the nitrogen content such as urea or banana stem waste. The most optimal composting results are obtained from comparing the composition of teak leaf waste and cow dung from 400 g of teak leaf waste: 100 g.

Gastrointestinal nematodes are a type of parasitic worm that is found in the digestive tract of humans and animals and can live in all areas, including fresh water, sea and land with a supportive environment. This research was to look at the percentage of gastrointestinal nematode infestation in cattle in Bireuen Regency as a lowland area from various levels of age groups and gender. The research samples were feces from 120 cattle divided into 3 age groups (0-6 months, 7-12 months, >12 months) and 2 genders (female and male). The examination was carried out using the centrifuge method. Samples are declared positive if gastrointestinal nematode eggs are found and the percentage is calculated using the prevalence formula and looking at differences in infestation levels analyzed using the chi-square formula. The research results showed that in the age group 0-7 months it was 35%, 7-12 months it was 22.5% and >12 months it was 15%. Between age groups the presence of these worms showed significant differences (P<0.05). Meanwhile, based on gender, female cows have a higher infestation, namely 23.9% compared to 15.2% for male cattle and there is a significant difference (P<0.05).

This research aims to explore the potential of dragon fruit waste as a source of biohydrogen through anaerobic fermentation. The research background highlights the urgency of renewable energy and identifies the potential for dragon fruit waste. Using experimental methods and involving dragon fruit waste and cow dung, this research includes evaluation of waste characteristics, inoculum pre-treatment, medium preparation, biohydrogen production, and analysis of results. The research results show that Total Solids (TS) has increased every day, indicating that there is still high decomposition of organic material which affects biohydrogen production. The test results showed that the TS percentage experienced a significant increase in solids content reaching 96% on the seventh day, while the VS percentage increased from 19% on the first day to 80% on the seventh day. The increase in Volatile Fatty Acid (VFA) concentration and hydrogen production on the sixth day illustrates the potential of waste as a renewable energy source. The conclusion of this research states that dragon fruit waste has the potential for biohydrogen production of 4 mL from a substrate volume of 500 mL or around 0.8%.

In the Coal-Fired Power Plant (CFPP) operation, various pollutants will be generated, including Particulate Matter (PM), which can be monitored with the Continuous Emission Monitoring System (CEMS). The parameters monitored include PM concentration, volumetric flow rate, % O2, and the operation hours and/or CEMS monitoring hours. Emission load calculation by utilizing CEMS data is a Tier 3 calculation method that uses real operation data from a CFPP unit. Information related to PM emission load from CFPP can be considered for corporate decision making in developing emission control strategies. This research utilizes secondary data from January 2021 to July 2023 period, from 52 PT PLN (Persero)’s CFPP units with various boiler, installed capacity, and types of Air Pollution Control Devices specifications. The largest average/month emission load value is 139,632 kg PM/month for CFPP unit that uses PC boiler, have a capacity of > 600 MW, and use low NOx burners and ESP as its APCD; while the smallest average/month emission load value is 525 kg PM/month for CFPP unit that uses PC boiler, have a capacity of 101-300 MW, and use ESP as its APCD. If the average emission load/month from January 2021 to July 2023 is compared with the maximum emission load/month with a PM quality standard of 100 mg/Nm3, all CFPP units do not exceed it and are generally ready to face the tightening of PM quality standard up to 75 mg/Nm3.

Cidanau River water is one of the important facilities for the people of Padarincang District. People use the river flow for their daily needs. Along its course there are non-densely populated settlements, where residents dump domestic waste into rivers. The purpose of this study is to analyze river water quality, the amount of raw water needs and the feasibility of the Cidanau River. The study used quantitative methods in the form of water sampling, population growth projections and river water feasibility by analyzing the water quality of the Cidanau River with the Pollution Index (IP) method. The results of the pollution index can be concluded that the Cidanau River meets quality standards based on class II criteria with the lightly polluted category because the IP results show a value of 2.84 which means 1 ≤ IP ≤ 5. Based on the results of data processing of projected population of Padarincang District in the next 10 years amounting to 103,440 people, the total clean water needs of Padarincang District are 149,618,181 m³ / day. It can be concluded that based on the water needs of the Padarincang District Population of 149,618,181 m³ / day with a discharge of 1.2269 m³ / day is said to be unfeasible because the river water discharge < water needs.

Climate change is a real phenomenon that occurs and is felt by all living things that live on earth. The increase in earth's surface temperature is one of the impacts of climate change that continues to occur and has the potential to threaten the sustainability of human life. Carbon dioxide is the main greenhouse gas that exacerbates this condition. One of the largest sources of carbon dioxide emissions comes from the energy sector, namely coal-fired power plants (CFPP). Java Island has CFPP’s with the largest total installed capacity in Indonesia, even the capacity will continue to be added by 8,5 GW or 39,4% until 2030. In its operation, the CFPPs have an air emission measuring device before being discharged into the atmosphere which works continuously called the Continuous Emission Monitoring System (CEMS). To be able to take appropriate climate change mitigation and adaptation steps, CO2 emission load data that has high accuracy and is analyzed directly is needed. The CO2 emission load generated from 20 CFPP units as the object of research is 88,56 million tons of CO2/year. The greater the generating capacity, the greater the CO2 emissions produced. The higher the quality of coal used, the lower the CO2 emissions tend to be. To support global efforts to combat climate change, mitigation actions are needed to reduce CO2 emissions into the atmosphere.
