This study aims to analyze the water quality of the Badung River based on Class II River water quality standards according to Government Regulation No. 22 of 2021, determine the water quality status, and calculate the potential pollution load of the Badung River. Water quality measurements were conducted at five sampling points. The parameters measured and observed include Temperature, Total Suspended Solids (TSS), pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), Sulfate (SO42), Nitrate (NO3), Total Phosphate (P), Oil & Grease, Total Detergent, and Total Coliform. Samples were analyzed in the laboratory for physical, chemical, and microbiological parameters. The water quality status of the Badung River was determined using the pollution index method, and the potential pollution load was calculated using the wastewater emission coefficient approach. The results showed that the water quality and status of the Badung River are classified as lightly polluted, with an average pollution index value of 3.65. The potential pollution load entering the Badung River in the domestic sector is 0.78 tons/day for BOD, 1.07 tons/day for COD, and 0.74 tons/day for TSS. Factors contributing to the lightly polluted water quality status include population density, poorly managed domestic activities (household waste), which contribute to high pollution parameter values such as BOD, COD, and TSS, and a lack of waste management infrastructure

Climate change presents a significant global challenge that requires urgent and comprehensive action to mitigate its adverse effects on ecosystems, society, and the economy. Islamic jurisprudence, with its rich ethical framework, offers valuable insights into environmental justice, presenting a Sharia-informed approach to climate change mitigation. This study explores how principles of Sharia, such as Hifz al-Bi'ah (protection of the environment), Amanah (trust), and Isrāf (prohibition of wastefulness), can form a robust foundation for addressing environmental issues. Islamic law emphasizes the responsibility of humans as stewards of the Earth, encouraging sustainable resource management and the prevention of environmental degradation. The study further discusses how Sharia provides a proactive approach to environmental justice, focusing on prevention rather than simply reacting to environmental damage. Additionally, it explores how Islamic principles align with international environmental frameworks, offering a holistic approach to climate justice that respects both local traditions and global imperatives. The findings highlight the potential for integrating Sharia-based principles into contemporary environmental policies, particularly in Muslim-majority regions, where these values can enhance the legitimacy and effectiveness of climate change mitigation efforts. The paper concludes with recommendations for further research on the practical integration of Sharia principles into global climate policies and calls for collaboration among Islamic scholars, legal experts, and environmentalists to develop actionable, Sharia-based environmental policies that contribute to global climate action.

This journal looks at the legal concerns of managing natural resources by producing compost using a market-based method based on garbage. This study's primary goal is to evaluate the efficacy and compliance of the legal requirements controlling the use of market trash as a raw material for compost fertilizer. The study's findings indicate that there are several pertinent laws that offer a legal framework for market waste management, including the Environmental Law and government waste management rules. However, there are obstacles to the law's implementation and enforcement, such as a lack of knowledge among business actors and oversight flaws. To ensure sustainability and efficiency in managing market waste as a resource for making compost, this study also found that, despite the existence of existing regulations, regulatory updates and harmonization are still required. To maximize the environmental and economic benefits of market waste management, this research recommends improvements in regulations and law enforcement, as well as increased education and training for business actors.The results of the study indicate that the utilization of market waste for making compost has great potential in supporting organic farming and reducing the volume of waste that ends up in landfills. However, the implementation of this program requires a deep understanding of applicable regulations, as well as support from the government and the community. This article concludes that comprehensive legal-based waste management can improve the efficiency and sustainability of natural resource management, as well as have a positive impact on community welfare.

Waste is a waste product of human activities that continues to increase along with the increase in population, activities, and consumption levels. In Bengkalis Sub-district, Bengkalis Regency, there are many waste accumulation points that have not been handled properly, mainly due to the lack of information about the location of waste accumulation. This causes the Bengkalis Regency Environment and Hygiene Agency (DLHK) to have difficulties in managing waste transportation, even though it is carried out every day. There are still many complaints from people who are outside the waste collection point. To overcome this problem, this research aims to develop a mobile application-based garbage pile complaint application focused on the Bengkalis District area. This application is designed to assist DLHK in monitoring environmental cleanliness more effectively. The Analytical Hierarchy Process (AHP) method is used to determine the priority of handling waste complaints, which will be implemented in a web platform to ensure optimal handling. Application development uses a prototype approach to ensure that the resulting application is in accordance with user needs and expectations. With this application, it is hoped that waste management in Bengkalis Regency will become more efficient and responsive to community complaints.

The small number of people cultivating horticultural crops, especially vegetables, means that people can only buy vegetables to meet their vegetable food needs, where the main factor for this is the decline in the area of productive land used as agricultural land and cultivation caused by the growth of population density in Indonesia. Therefore, the solution to the existing problem is to provide openness of insight and assistance in utilizing narrow land for plant cultivation. One way to cultivate plants is by using the vertical cultivation method. In implementing this activity, the aim is for Kalijudan residents to have knowledge about the vertical cultivation system and plastic bottle waste management. The implementation of this activity uses the method of socialization and training activities or direct practice. Where, the target audience in the practice of this activity is elementary school students and Kalijudan residents. From the results of the discussion, it was concluded that this activity is useful because it can introduce residents and change the condition of the Kalijudan sub-district which was originally a narrow land without plants into a narrow but green land. In addition, this vertical cultivation activity also has benefits in reducing plastic waste that accumulates in the Kalijudan environment.
