Suggestions that can be given in this research are that hospital efforts are needed to maintain the quality of food services by paying more attention to the accuracy of diet for patients.

Due to the continuously increasing volume, the difficulty in distinguishing types of waste, and the heightened public awareness of environmental cleanliness, waste is the result of activities that are no longer used in the production process, so stakeholders must have the ability to manage waste effectively. One of the current problems is trash bins; the trash bins currently in use are only designed to transport waste materials without any other purpose.

Companies operating in the electricity accumulator industry sector, in the production process produce waste in the form of hazardous and toxic materials (B3). The management of B3 waste is carried out based on the provisions stated in the Regulation of the Minister of Environment and Forestry Number 6 of 2021 concerning Procedures and Requirements for Hazardous and Toxic Waste Management. Therefore, the waste generated requires special handling to prevent environmental pollution. Therefore, the waste generated requires special handling so as not to pollute the environment. Hazardous waste management in the electricity accumulator industry includes various stages, both for waste in the solid and liquid phases, namely identification, inventory, packaging, labeling and symbolization, storage, and transportation carried out by third parties. This research aims to assess the current condition of hazardous waste management in the electricity accumulator industry, evaluate it, and provide recommendations that are in line with applicable regulations. The research method used is a descriptive approach. In the inventory process, the electricity accumulator industry requires Temporary Storage Sites (TPS) to store B3 waste before transportation by third parties.

Plastic waste is widely found in the environment. Degraded plastic waste eventually forms microplastics. Microplastic pollution has been widely found in various elements in the environment, such as in water, in the air, in organisms, and in salt. The study of microplastics in salt in Indonesia is still very limited, so a literature review was carried out on research carried out in the time period from 2020 to 2024. The parameters observed included abundance, shape, size, color and type of microplastics. The abundance obtained was between 46 particles/kg to 29 particles/g or assumed to be equivalent to 29,000 particles/kg in coarse salt. The abundance of microplastics in commercial salt was between 40 particles/kg to 306.67 particles/kg. The forms of microplastics found included fibers, films, fragments, filaments, and pellets. The microplastics found were black, transparent, red, blue, green, purple, brown, and white. Meanwhile, the size of the microplastics found was between 0.017 mm to 4.936 mm. Microplastic types were only found in one article, including polyvinyl chloride (PVC), polyurethane (PU), polyester, nylon, and polyethylene terephthalate glycol (PETG).
