Iodine deficiency remains a major health issue, especially in highland regions like Cisukadana Village, leading to an increased risk of goiter that affects metabolism and growth. This study explores an alternative method to improve iodine intake through the use of factory ash waste in salted egg processing. Factory ash waste is known to contain microelements such as iodine, calcium, and magnesium, which can enhance the nutritional value of salted eggs. The research consisted of three stages: community counseling on iodine importance, practical training on making salted eggs using a salt and ash mixture, and product distribution for evaluation. Eggs were soaked in a brine solution mixed with ash waste for 8–10 days to ensure iodine absorption. The results showed that this method increased iodine content in the eggs, extended shelf life, and improved texture and taste. The program positively impacted the community in health (goiter prevention), social (community involvement and student participation), and economic (potential new business using local resources) aspects. This innovation demonstrates a sustainable approach to enhancing iodine intake while reducing industrial waste impact.

This study uses a library research method to explore how systematic budget planning can improve financial efficiency and ensure transparent and accountable use of funds. This study highlights the importance of preparing formal documents such as annual work plans, budget work plans, and RAPB in ensuring that organizations can manage resources in a more structured and measurable manner. By applying analysis to various literature sources, this study identifies steps in preparing an effective RAPB, including revenue estimation, expenditure allocation, and budget evaluation and control mechanisms. The results of the study show that a well-prepared RAPB can help organizations set priorities, measure performance, and avoid waste of resources. In addition, RAPB also acts as an internal communication tool that clarifies the direction and goals of the organization to all stakeholders. With a strict evaluation system, organizations can ensure that the budget used has an optimal impact on achieving the vision and mission that have been set.

Utilization of fermented layer chicken excreta as a feed medium for Black Soldier Fly (BSF) maggots is a sustainable solution for organic waste management. Chicken excreta contains 13-32% crude protein, but has disadvantages such as unbalanced nutrient composition and unpleasant odor. Fermentation of chicken excreta can improve maggot production performance by reducing pathogens, odor, and facilitating digestion. The growth medium of 50% excreta + 50% tofu dregs produced the highest PK, which was 34.34%. The lowest SK and LK were obtained from the growth medium of 50% excreta + 50% tofu dregs and 25% excreta + 75% tofu dregs. Based on physical conditions, the longest and heaviest maggot sizes were obtained from the growth medium of 50% excreta + 50% bran + 5 ml EM4. Meanwhile, the shortest maggots were obtained from the growth medium of 75% coconut dregs + 25% excreta and the lightest maggots were obtained from the growth medium of 100% excreta.

Waste sorting is one of the important steps in sustainable environmental management. However, elementary school students' awareness in sorting organic and non-organic waste is still relatively low. This can have an impact on increasing the volume of waste that is not managed properly, which ultimately contributes to environmental pollution. This community service aims to measure the effectiveness of the use of two-compartment trash bins in improving students' understanding of waste sorting. The method used is observation with an action study approach on elementary school students. The results of observations after socialization showed an increase in students' understanding after the use of two-compartment trash bins, which was reflected in the increased accuracy in disposing of waste into the appropriate compartment. The use of two-compartment trash bins has proven effective in increasing students' awareness and habits in sorting waste.

The Jelekong landfill was a temporary landfill site following a landslide at the Leuwigajah landfill. TPA Jelekong was officially closed at the end of 2005 because it was no longer able to accommodate the increasing volume of waste. However, the impact of activities from the former landfill still has the potential to pollute the environment, especially groundwater sources. The research aimed to identify the physical and chemical parameters of water in the Jelekong ex-landfill case study area and the surrounding area, and to compare the physical and chemical parameters of water between the Jelekong ex-landfill and the landfill that is still operating (Sarimukti landfill). Data were obtained from 4 water sample points and tested using several test methods, namely Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Ion Chromatography (IC), alkalinity, and stable water isotopes. The results showed that the physical characteristics of the Jelekong area generally have a neutral pH with one point having an alkaline pH (JL-02) due to interaction with andesite lithology and the highest DO concentration at point JL-02. While the Sarimukti landfill has a pH value of 7.89-8.27 indicating the result of high bicarbonate concentrations, the TDS value of 15700-18200 ppm indicates the large number of ions and solutes derived from organic and inorganic waste. Piper diagrams show two water facies in the Jelekong area, Ca-HCO3 and Na-HCO3. Sample JL-03 indicates a mixture with landfill leachate due to high Cl and SO4 concentrations. Sample JL-01 still indicates leachate because when compared to the sarimukti sample, the Cl and SO4 concentrations are still quite high indicating a result of both organic and inorganic waste. Stable isotope test results indicated that the water was derived from local precipitation.

Environmental health such as proper medical waste management in accordance with existing requirements. The purpose of this study was to determine the sources of infectious medical waste at RSUD Haji Makassar. The research method used is a qualitative method with a post-positivistic or enterprising approach and observation. The types of data used are primary and secondary data. The results of the study indicate that at the sorting and reduction stage it has been implemented but in the sorting section there are still errors in plastic bags not being labeled regarding the type of waste, at the storage stage there are still errors in temporary storage places that can be accessed by animals, at the transportation stage there are still some that are not in accordance with the Regulation of the Minister of Environment and Forestry Number 56 of 2015 such as medical waste managers also do not use complete personal protective equipment and do not have a special route for waste transportation, at the processing stage it is not carried out because the incinerator in the hospital does not have an operational permit and at the stockpiling and burial stages it is also not carried out because medical waste management has been handed over to a third party. RSUD Haji Makassar pays more attention to all waste management processes that are not yet adequate and the management of incinerator use permits for better waste management.

Indonesia is a tropical country which of course cannot avoid the occurrence of dengue fever. engue fever is still one of the serious diseases faced in Indonesia. The results of the Ministry of Health of the Republic of Indonesia in 2022, the number of dengue cases reached 131.265. Prevention and eradication measures are more effective by eradicating mosquito larvae with PSN. PSN efforts require cooperation between the government and community participation. The role of eradicating mosquito nests must always be increased, includes draining water reservoirs, tightly closing water reservoirs, reusing used goods that can hold water and have the potential to become breeding grounds for mosquitoes that transmit dengue fever. In general, most residents use water reservoirs and there are piles of rubbish around the house and there are still puddles and water reservoirs. For this reason, there needs to be education for the community about eradicating mosquito nests, one of which is by utilizing used goods so that they do not become a place for the shelter and development of mosquito larvae that cause dengue fever. The method used in this community service is by providing education and counseling to the community regarding explanations regarding waste management, sorting, benefits and recycling of waste. The implementation of this PkM activity went well and smoothly. The community was enthusiastic in participating in this activity. There was an increase in public knowledge and understanding during the discussion session of the activity. It is hoped that the community can manage waste properly and correctly to avoid various diseases, especially Dengue Fever (DBD).

The large amount of used cooking oil that is thrown into the environment by the community is an urgency that must be addressed.
