The waste problem in Indonesia has now reached a critical stage and has become an increasingly serious environmental issue. The ever-increasing volume of waste is not being managed effectively, leading to various negative impacts, particularly environmental pollution. This study aims to examine the state of waste management in Indonesia and its impact on water pollution from the perspective of the Sustainable Development Goals (SDGs). The method used is descriptive qualitative research through a literature review utilizing various sources such as journals, official reports, and legislation. The results indicate that the majority of waste originates from household activities, while management practices remain rudimentary, such as the “collect-transport-dispose” method and open dumping. This situation leads to waste accumulation, which contributes to water pollution, deteriorating environmental quality, and increased health risks for the community. Furthermore, suboptimal waste management also poses a challenge in achieving sustainable development goals, particularly regarding responsible consumption and access to clean water and sanitation. Therefore, improved efforts are needed through the application of the reduce, reuse, recycle (3R) principles, increased public awareness, and the active role of the government and the private sector in providing a sustainable waste management system. With the right measures, it is hoped that the waste problem in Indonesia can be reduced and the environment preserved.

This study examines the environmental advocacy strategies carried out by WALHI Jambi in addressing the pollution of the Batanghari River caused by illegal gold mining activities. This issue reflects ongoing environmental degradation and weak policy enforcement in managing natural resources. The study aims to analyze advocacy practices in terms of raising public awareness, community organizing, and influencing policy. A qualitative approach with a case study method was employed, with data collected through in-depth interviews, observation, and document analysis. The findings show that WALHI Jambi has undertaken various advocacy efforts, including media campaigns, public actions, community assistance, and engagement in policy forums. However, these efforts remain not fully optimal. Public awareness initiatives are still limited to information dissemination, community organizing has not yet developed into a strong collective movement, and policy influence is constrained by the absence of systematic instruments such as formal documentation, litigation, and structured coalitions. This study contributes to the understanding of environmental advocacy practices and highlights the need for strengthening advocacy strategies to achieve more effective policy influence and sustainable environmental governance.

Industrial development in Indonesia has significantly contributed to national economic growth; however, it also poses potential risks of environmental pollution when corporate waste management is not conducted properly. Environmental pollution resulting from corporate waste activities may cause harm to surrounding communities, including health problems, ecosystem degradation, as well as material and immaterial losses. In this context, the class action mechanism serves as a relevant legal instrument to collectively advocate for the rights of affected communities. This study aims to analyze the implementation of the class action mechanism in environmental pollution cases based on Decision Number 29/Pdt.G/2023/PN.Skh and to evaluate its effectiveness in providing legal protection and restoring the rights of affected communities. This research employs normative legal research using statute approach, case approach, and conceptual approach. The findings indicate that the class action mechanism in the aforementioned decision fulfilled the requirements of numerosity, commonality, typicality, and adequacy of representation as regulated under Supreme Court Regulation (PERMA) Number 1 of 2002. Procedurally, the class action proved effective in enhancing access to justice, ensuring judicial efficiency, and strengthening the protection of the constitutional right to a good and healthy environment. However, its substantive effectiveness remains dependent on the fulfillment of formal requirements, the quality of evidence presented, and the consistent application of environmental law principles by judges. Therefore, the class action mechanism constitutes an important instrument in environmental law enforcement, yet it requires consistent regulatory support and judicial practice to achieve optimal ecological justice.

The Ciliwung River Basin is a strategic watershed with significant ecological, social, and economic functions, yet it is increasingly threatened by land use change, rapid urbanization, and water pollution, particularly in the Jakarta metropolitan area. This study aims to assess the water quality condition of the Ciliwung River based on real time monitoring data from the ONLIMO system and to examine spatial and temporal variations in water quality status along the middle and downstream segments. A descriptive quantitative approach was applied using secondary data obtained from three ONLIMO monitoring stations, namely Masjid Istiqlal, Pintu Air Manggarai, and Kelapa Dua Srengseng Sawah, during the period of 6–12 May 2025. The analyzed parameters included temperature, dissolved oxygen, Biochemical Oxygen Demand, nitrate, ammonia, and other relevant physicochemical indicators. The results indicate that the water quality of the Ciliwung River generally falls within lightly to moderately polluted categories, with higher pollution levels observed in the middle segment of the river. Critical parameters influencing pollution status include Biochemical Oxygen Demand, nitrate, ammonia, and consistently low dissolved oxygen levels. These findings demonstrate that pollution in the Ciliwung River is persistent and cumulative, highlighting the urgency of integrated watershed management, strengthening real time water quality monitoring, and enhancing cross sector collaboration to support effective pollution control and sustainable river restoration.

This study aims to analyze the process of processing fruit peel waste from juice traders into eco-enzymes as an effort to reduce environmental pollution. The research uses qualitative descriptive methods through direct observation, documentation, and literature studies. Fruit peel waste is fermented at a ratio of 1:3:10 (molasses : fruit waste : water) for three months under anaerobic conditions. The fermentation results show good eco-enzyme characteristics, characterized by a pH of 3, a fresh sour aroma, and a brownish color as an indicator of fermentation success. These findings show that the process of processing eco-enzymes from fruit peel waste can be done simply, cheaply, and environmentally friendly. In addition, the use of eco-enzymes has the potential to reduce the volume of organic waste disposed of in landfills and reduce water and soil pollution. The resulting eco-enzyme also has potential applications as natural cleaners, liquid fertilizers, and odor controllers. Thus, the treatment of fruit peel waste not only supports sustainable environmental management practices, but also encourages the implementation of the circular economy as well as community empowerment ecologically and economically.

The implementation of ballast water management is a very important strategic step in preventing marine environmental pollution, because ship ballast water often becomes a route for the spread of invasive alien species that have the potential to disrupt the balance of the ecosistem, harm the maritime economic sector, and endanger human health. This study focuses on ballast water management practices on the MT Timur Laut Mas 2 ship, with the aim of assessing how the procedures are implemented in order to prevent the entry of alien species, reviewing the implementation of both international and national regulations, and evaluating the performance of the Ballast Water Management Sistem (BWMS) technology applied. This study uses a descriptive qualitative method based on a case study, with data collection through interviews with ship crews and company management, direct observation on board the ship, technical documentation, and a review of supporting literature. The results of the study show that the implementation of the IMO Ballast Water Management Convention (BWMC) regulations on ships has been realized through the preparation of a Ballast Water Management Plan, detailed recording in the Ballast Water Record Book, and the use of a BWMS that relies on filtration technology and ultraviolet radiation. However, the implementation still encounters obstacles in the form of limited crew understanding of system operation, variations in water quality along the shipping route that affect filtration effectiveness, and technical obstacles in equipment maintenance. Therefore, a combination of compliance with international regulations, improving crew competency through continuous training, and optimizing sistem operations are key factors in strengthening the effectiveness of ballast water management. These findings confirm that the application of modern technology in accordance with regulatory requirements can enhance marine ecosistem protection while ensuring the sustainability of the maritime industry, thus positively contributing to environmental sustainability and the stability.

This study discusses a legal analysis of the differences between criticism and defamation in Indonesian law, especially in the Criminal Code (KUHP) and Law Number 1 of 2024 concerning the Second Amendment to Law Number 11 of 2008 concerning Electronic Information and Transactions (UU ITE). The research method used is normative legal with a regulatory and contextual approach. The results of the study show that the Criminal Code and the ITE Law both provide protection for individual honor, but differ in the scope of application. The Criminal Code focuses more on conventional interactions, while the ITE Law regulates the electronic realm. Although it aims to protect the name well, the provisions in the ITE Law are considered to have weaknesses due to the potential for multiple interpretations that can threaten freedom of expression. Therefore, a proportional legal interpretation is needed to maintain a balance between protection of personal honor and respect for freedom.  

Pollution of hydrocarbons in marine waters was recorded up to 2003 around 6.44 million tons and dominant due to the results of fishery port activities to cause the balance of coastal ecosystems disrupted. The drained state funds for its handling can reach 1000 USD per ton up to 33,000 USD in each region. Various efforts have been made is still not effective enough. The purpose of this program is to get the appropriate technology design in overcoming the problem of hydrocarbon pollution in the fishing port. The method used by literature and field study and a series of testing tools. The solution is called MABOA (Magic Briquette Oil Absorbent) is a technology that is applied aplikatif appropriate to overcome the problem of oil pollution in the port area. This tool is a net with the main components of magic briquettes, auto-spray containing bacteria degradation and microcontroller which as a whole has the ability to absorb and degrade hydrocarbon compounds. The circular MABOA net will prevent the expansion of the oil spill zone by the absorption process by magic briquettes. Pseudomonas puttidae and Bacillus sp. In auto-spray will be automatically sprayed over the surface of the spill zone to perform the decomposition of hydrocarbon compounds. Bacteria will grow and utilize hydrocarbons that have been absorbed and accumulated in the body of magic briquettes so that the cleaning process becomes more effective and faster. Results from a series of trials showed that MABOA with 3meter diameter dimension able to absorb hydrocarbon compound as much as 35.000mL with 3-5min time absorption rate and with density of colonies of bacteria 3,5x109 able to degrade 32% of existing hydrocarbon compound with efficiency time 3-7 days. The data is an accumulation of those component test result data.

The increase in human activities, such as industrialization, urbanization, and transportation, has led to air pollution, including heavy metal contamination such as lead (Pb). Lead originates from vehicle emissions, industrial activities, and fossil fuel combustion, which have detrimental effects on the environment and human health. One effective method for monitoring air pollution is biomonitoring using bioindicators, such as lichen. Lichen is sensitive to air quality and can absorb pollutants, including heavy metals, through its surface. This study uses a literature review to analyze the role of lichen as a bioindicator of heavy metal pollution, specifically lead. Several lichen species, such as *Xanthoparmelia xanthofarinosa* and *Canoparmelia aptata*, are known to accumulate heavy metals from the environment. The results show that the lead content in lichen varies depending on the pollution level in the location. Areas with high traffic have higher lead concentrations compared to areas with low traffic. The advantages of using lichen as a bioindicator include low cost, practicality, and its ability to provide long-term data on air quality. With this understanding, lichen data can be used for pollution mitigation and evidence-based policies to reduce the impact of air pollution. Further research is recommended to explore the potential of lichen in detecting other heavy metals, such as cadmium (Cd) and copper (Cu).

The issue of criminalizing victims of sexual violence through the use of defamation charges is gaining public attention because it is often used to silence victims who try to share their experiences. This article describes how defamation provisions in the Criminal Code and the Electronic Information and Transactions Law are often used as instruments of Strategic Lawsuits Against Public Participation (SLAPP) directed at victims, making victims even more vulnerable. The study uses a normative approach to assess the effectiveness of legal protection in the Sexual Violence Criminal Law (TPKS Law). The results of the analysis show that the TPKS Law does not explicitly include an anti-SLAPP mechanism, leaving open the possibility for the reported party to file a counter-report against the victim. Studies of the SPI, KPI, and Baiq Nuril cases show a recurring pattern, namely the use of defamation articles as a means of silencing victims and slowing down the process of exposing sexual violence. This article proposes an anti-SLAPP clause based on a progressive interpretation of the anti-revictimization principle in the TPKS Law. This proposal is reinforced by the push for the application of an early dismissal mechanism for reports that show strong indications of intimidation, so that victims receive maximum protection in the legal process.
