The Effectiveness of Constructed Wetlands in Managing Coal Mining Wastewater

2024-12-06T04:58:55+00:00

Mining activities, especially coal mining, produce wastewater containing heavy metals such as manganese and iron, which can degrade water quality and harm ecosystems. Effective wastewater management is crucial to meet environmental quality standards and reduce ecological risks. This research aims to evaluate the effectiveness of constructed wetlands in treating coal mine wastewater by assessing critical water quality parameters such as pH, Suspended Solids (TSS), Total Iron (Fe), and Total Manganese (Mn). The research uses a descriptive method involving field sampling and laboratory analysis. Water samples were collected from settling pond BB-18 PPA-BA, both before and after the installation of constructed wetlands. The parameters tested include pH, TSS, Total Iron, and Total Manganese, following standard environmental testing protocols. The implementation of constructed wetlands significantly improved water quality. The measured values after treatment were pH 6.90, TSS 18.20 mg/L, Total Iron 0.31 mg/L, and Total Manganese 2.75 mg/L, all within permissible environmental quality standards. Constructed wetlands effectively reduce pollutants in coal mine wastewater, enabling compliance with environmental quality standards. This approach combines active and passive treatment methods, providing a sustainable and cost-effective wastewater management solution for coal mining operations.

The results showed that, the guyang jaran ritual means bathing horses in the sendhang which starts from installing offerings to end praying together at pepundhen as a form of respect for ancestral spirits, repelling bad luck, and preserving culture. Some types of ubarampe used are tumpeng, sega kapirata, sega bakar, endhog jawa, ingkung, cambah pethek, juaddah pasar, jenang abang putih, incense, candles, cigarettes, kembang setaman, kembang durang, kembang wangi, degan ijo, and wedang 7 werna. Overall, the ubarampe in the guyang jaran ritual has the meaning of prayer requests, gratitude, and a form of harmonious relationship between humans and nature as well as a medium for the Legoksari village community and makes it integral in cultural and spiritual practices.

The Influence of Regional Own-Source Revenue, General Allocation Funds, Special Allocation Funds, and Capital Expenditure on Regional Financial Independence Through Economic Growth in North Sulawesi Province

2024-12-06T06:35:42+00:00

In the context of fiscal decentralization in Indonesia, regional financial independence represents a significant challenge, given the considerable dependence on central fund transfers, including the General Allocation Fund (DAU) and the Special Allocation Fund (DAK). This issue is further compounded by suboptimal management of local own-source revenues (PAD) and ineffective capital expenditure allocations, which have a detrimental impact on infrastructure development and economic growth. Fiscal imbalances between regions also contribute to the widening of economic disparities, impeding efforts to achieve sustainable financial independence. This study aims to analyze the influence of Regional Original Revenue (PAD), General Allocation Fund (DAU), Special Allocation Fund (DAK), and Capital Expenditure on the level of regional financial independence through economic growth in North Sulawesi Province. Using secondary data from the 2011-2023 period, the path analysis method was applied to evaluate the direct and indirect relationships between variables. The results of the study show that PAD has a significant positive effect on economic growth and regional financial independence. DAU and DAK, although contributing to fiscal needs, show varying influences on economic growth and financial independence. These findings emphasize the importance of optimizing PAD and capital expenditure allocation to support economic development and reduce dependence on central fund transfers.
