Abstract

The Tailings Storage Facility (TSF) is one of the largest constructions in mining activities involving sediment ponds that is an important and common facility used in mining activities. This study aims to recommend safe and environmentally friendly water management in settling ponds. This research is done by analyzing rainfall using E. J. Gumbel Method and designing a mine drainage system. The prediction results produce a maximum rainfall of 20.99 mm/day and a rain intensity value of 7.28 mm/hour. The catchment area is 380,355 m2 and the total runoff water discharge is 0.64 m3/second. Runoff water enters the settling pond with a volume of 2,438 m3/day. The capacity of the 3 (three) compartments of settling ponds is 4,500 m3 and an area of 500 m2.

Abstract

Reclamation of ex-mining land is an obligation that must be carried out by every mining business actors, in order to organize, restore, and improve the quality of the environment and ecosystem so that it can function again according to its designation. However, this obligation has not been carried out consistently by manganese mining companies in West Timor. Based on the results of supervision carried out by mining inspectors, no company has carried out reclamation. This study aims to identify factors that influence the implementation of reclamation governance for ex-mining manganese land in West Timor. Case studies were conducted on eigth location of Izin Usaha Pertambangan (IUP) in West Timor, East Nusa Tenggara Province. Data collection was carried out through questionnaires, interviews, and field observations. Furthermore, data analysis used qualitative descriptive methods. The results of the study indicate that the inhibiting factors for achieving successful reclamation of ex-mining land in West Timor are the licensing process, supervision, competence of mining business actors, and community involvement. In this regard, further research is needed to examine the form of reclamation that is in accordance with the conditions of ex-mining manganese land in West Timor.

Abstract

Indonesia, with its tropical climate and high rainfall, especially near the equator, is prone to slope instability influenced by intense rainfall events. Rainfall increases pore water pressure, reduces effective stress, and decreases shear strength, which in turn lowers the safety factor and increases the probability of failure. However, studies on pore pressure changes during rainfall infiltration have not been extensively studied, particularly in Indonesia. This study aims to analyze the effect of rainfall on the stability of a single slope in a waste dump using a numerical method based on a coupled hydro-mechanical approach. Simulations were conducted using transient finite element analysis (TFEA) to evaluate pore water pressure variations. In addition, the limit equilibrium method (LEM) modeling was also carried out to assess changes in slope safety factors. The analysis was performed using Slide2 software under various rainfall and duration scenarios, with a total of 1,568 model combinations over a 24-hour simulation period. The results show that rainfall events reduce the safety factor value by up to 31.54%. The relationship between the safety factor value and rainfall can be expressed by the equation FK = 2,1607 CH-0,05, which shows a strong correlation with an R2 value of 0,9309.

Abstract

The presence of mining companies in regions with natural resource potential is often regarded as a source of economic hope for local communities. However, not all regions are able to optimize these resources to improve community welfare. In fact, some communities primarily experience the negative impacts of mining activities. Compensation funds serve as a corporate initiative for environmental management, particularly for affected communities. This study aims to analyze the factors influencing the amount of compensation provided. Data were collected through questionnaires distributed to affected residents. Using multiple linear regression analysis, the results reveal that income level and number of family dependents significantly influence the compensation value. The Adjusted R² of 0.551 indicates that 55.1% of the variation in compensation is explained by the independent variables, while the remaining 44.9% is attributed to other factors not examined in this study.
