This study aims to analyze the quality of leachate based on quality standards, examine the relationship between rainfall intensity and leachate quality, and assess the level of leachate pollution at the Talumelito TPA. The research employs a descriptive quantitative approach by collecting primary and secondary data. Primary data were obtained from leachate sample testing, while secondary data included rainfall intensity from the Gorontalo Climatology Station. The leachate samples, taken from the inlet and outlet of the reservoir on December 11, 2024, were tested for pH, BOD, COD, TSS, N-Total, Mercury, and Cadmium at LPPT UGM Yogyakarta and the UPTD Regional Health Laboratory Center of Gorontalo Province. The results indicate that from 2022 to 2024, five parameters at the inlet (pH, BOD, COD, TSS, N-Total) and four at the outlet (BOD, COD, TSS, N-Total) exceeded the quality standards set by PerMenLHK No. 59 of 2016. However, Mercury and Cadmium at the inlet and pH, Mercury, and Cadmium at the outlet met the standards. Rainfall intensity ranged from 9 mm (2023) to 235 mm (2022), but it did not significantly impact the leachate quality. Pollution index analysis using the IP and Storet methods showed an average IP value of 4.2, indicating light pollution, while the Storet classification placed the water quality in Class C (-18), meaning moderate pollution. These findings highlight the need for improved leachate treatment and management to mitigate environmental impacts at Talumelito TPA.

Community Development (CD) in Petroleum Industry of South Sudan: A Contextual Review

Community Development (CD), though a crucial element within the petroleum industry, has historically been neglected and insufficiently studied, particularly in relation to Corporate Social Responsibility (CSR). This disregard has led to CD initiatives being implemented remotely, with limited effectiveness. In South Sudan, despite having a mature and robust petroleum sector operating through three Joint Operating Companies (JOCs) in blocks 3 & 7, 1, 2 & 4, and 5A, CD programs and projects have largely employed a non-participatory (top-down) approach. As a result, communities often fail to take ownership of projects, leading to unsustainable development and eventual collapse of initiatives. The study emphasizes the importance of a participatory (bottom-up) model in which communities are at the core of all petroleum industry processes—from exploration, appraisal, development, and drilling, to production and decommissioning. The proposed model advocates for comprehensive community consultation and positions Participatory Rural Appraisal (PRA) as the central methodology. PRA enables communities to identify, prioritize, and address their most pressing issues through the creation and execution of a Community Action Plan (CAP). Using a case study approach, the research examined CD departments across all JOCs in South Sudan. It concludes that while the petroleum industry is capital-intensive, it is equally people-intensive and must be led by the communities themselves. It further recommends that Community Development Committees (CDCs) be directly elected and managed by locals, free from political influence, to ensure effective, inclusive, and sustainable development.
