Abstract

The manufacturing sector is widespread, and like with any other sector, it generates trash in the course of its operations. According to Government Regulation Number22, all service providers are obligated to engage in management. Finding out what kind of waste management system PT.Xuses is the main goal of this study. The data is gathered from primary and secondary sources. Based on the findings, liquid waste management has achieved a highly effective 99% removal of BOD5 and TSS, while solid waste management has achieved a suitable value of 70.46 percent.The recommendation given is that for liquid waste, test more parameters, not just 3 parameters, and for solid waste, make improvements based on parameters that are not by the applicable references, such as replacing the wastewater treatment plant with a Jumbo Bag, and so on

Abstract

As part of its operations, PT A, a corporation specializing in military equipment, generated solid hazardous waste. Their four distinct forms of solid hazardous waste are contaminated hazardous waste, used rags, wastewater sludge, and blasting residue. This study aims to analyze and assess the utilized Guttman scale in order to determine the origins and kinds of hazardous solid waste, as well as its characteristics, quantity, and management system. Based on these findings, recommendations and proposals will be provided. With an 88% score, PT A was deemed "Very Good" according to the findings. It is suggested that workers be educated to raise knowledge about the need to separate household trash from hazardous waste. Additionally, a monitoring system should be put in place to check the process on a regular basis, and decisive action should be taken to create a safer atmosphere.

Abstract

The issue of the spread of marine debris or " marine litter" is in the global spotlight due to its detrimental impact on ecosystems, humans and marine life. The focus of this research is on the coastal area of Kuta Bali, Indonesia, with the main objective of identifying the factors driving damage to marine ecosystems due to plastic waste. Using the DPSIR (Driving Force, Pressure, State, Impact and Response) method approach, this research analyzes the causes and effects related to this environmental problem, highlighting the pressure generated by marine plastic debris, describing the conditions in coastal areas and evaluating the impacts that arise. The results show that the coastal area of Kuta Beach, Bali, is facing serious challenges related to marine plastic waste that is destroying the environment around Badung Regency. As a prevention and control effort, it is recommended that education and training exist in each coastal area, aimed at increasing public awareness of waste management and the potential dangers of marine plastic waste to the environment, in the hope of creating a safer environment and sustainable coastal environment.

Abstract

PT X is one of the companies that generates hazardous waste from production and non-production activities. There are nine types of B3 waste generated, namely used oil, electronic waste, used batteries /feet, B3 contaminated mop, used B3 packaging, used refrigerant from electronic equipment, expiredproducts / raw materials, materials / products that do not meet technical specifications and productionresidues. The purpose of the study is to determine the source, suitability of B3 waste management carriedout by PT X and provide recommendations for improvement of non-compliant findings. This researchuses primary data collection methods and secondary data. The results showed the percentage of theoverall level of suitability of B3 waste management carried out by PT X obtained a value of 68.1% whichmeans it is included in the "good" category. Recommendations for improvement that can be given are thatthe packaging needs to be given a symbol that matches its characteristics and a label on each hazardouswaste packaging found at PT. X and using closed conveyance so that it can load category 1 and category2 B3 waste simultaneously by considering the compatibility of B3 waste.

Abstract

The problem of open defecation (BABS) and the lack of proper toilet infrastructure for the residents of Cikoneng Village, RT 2, Bandung Regency can have a negative impact, especially on the health aspect. The economic situation and lack of public awareness of cleanliness are factors that lead to many latrines being covered only by tarpaulins with bamboo/wooden walls. The communal latrines previously available in Cikoneng village were even less effective due to their non-strategic location and water quantity problems. The purpose of this research is to plan the construction of a Pour and Flush Toilet (PFT) in RT 02 by conducting observations, questionnaires and analysis of technical and non-technical aspects to achieve good sanitation. The results of the research show that 100% of the residents of Kampung Cikoneng RT 2 are aware of the importance of PFT and are willing to participate in the construction, which consists of 4 toilet units and a septic tank with a length of 8.5 m, width of 9 m and depth/height of 8.5 m.

Abstract

The problem of plastic waste generation is increasingly pressing in Indonesia. Thermal technology offers an alternative solution that is more environmentally friendly in managing plastic waste. This literature study aims to compare pyrolysis and gasification technologies in converting plastic waste into energy. The analysis was carried out by reviewing various relevant studies. The results of the study indicate that both technologies have the potential to reduce plastic waste generation and produce value-added products. Pyrolysis is a thermal decomposition process without oxygen that produces oil, gas, and charcoal. Gasification produces syngas that can be used as fuel. This process requires limited oxygen and produces more diverse emissions. The comparison between pyrolysis and gasification shows that the selection of the right technology depends on several factors, such as the type of plastic, the desired product quality, and environmental considerations. Pyrolysis is more suitable for oil production, while gasification is more flexible in producing various types of gas products. Overall, both pyrolysis and gasification have great potential in managing plastic waste. However, further research is needed to optimize the process and reduce environmental impacts. Thus, thermal technology can be a sustainable solution in overcoming the problem of plastic waste in Indonesia.
