Abstract

The research location is located at IUP PT. IFISHDECO, Tbk (122.168° - 122.204° East Longitude (BT) and 4.371° - 4.404° South Latitude (LS), Tinanggea, South Konawe Regency, Southeast Sulawesi Province.. The study aims to determine the surface flow direction and catchment area model at nickel mining sites. The data is in the form of topographic data measured with a total station, by conducting spatial analysis with Quantum GIS (QGIS) and remote sensing with the Strahler method in determining the river network. The results of research conducted at the research location obtained 3 catchment areas, namely Catchment 1 covering an area of 19,021 Ha, catchment 2 covering an area of 32,691 Ha and Catchment 3 covering an area of 59.77 Ha which can be used in further analysis in the mining drainage system.

Abstract

Indonesia’s mining sector, particularly in areas like Morowali Regency, Central Sulawesi, faces significant geotechnical challenges due to its location in the Pacific Ring of Fire. One of the key concerns in open-pit mining operations is slope instability, which can lead to landslides, threaten worker safety, damage infrastructure, and disrupt production. This study evaluates the slope stability in the Sambalagi site of PT. Wosindo Berkat Abadi using the Morgenstern-Price method, a limit equilibrium approach known for its accuracy in heterogeneous slope conditions. Field data were collected, including slope geometry, geological conditions, material strength, and hydrogeological factors. The safety factor (FK) was calculated based on geotechnical parameters such as cohesion, internal friction angle, and unit weight of the slope materials primarily saprolite and limonite. The actual slope FK value at PIT D was found to be 0.974, below the standard requirement (≥1.3) set by the Ministerial Decree No. 1827K/30/MEM/2018. To improve stability, a revised slope design was proposed, including reducing slope angles to 35°, increasing bench widths to 2 meters, and decreasing slope height per bench to 4 meters. The simulation of this revised geometry showed that it could achieve the required FK value. The study contributes to safer and more efficient mine planning by demonstrating the importance of integrating detailed geotechnical analysis in slope design, especially in tropical high-rainfall mining regions.

Abstract

The research location is located in Induha Village, Latambaga District, Kolaka Regency, Southeast Sulawesi Province. This study aims to determine the factors controlling landslides, and the types of landslides in the study area. The method used in this research is direct observation in the form of data collection and data collection that is found directly in the field including geological observations, taking rock samples, measuring slopes, and taking documentation of 3 points of landslides. Factors that control the occurrence of landslides in the study area are influenced by controlling factors, namely very steep slopes with a slope of around ± 62o – 67o. Lithological conditions are metamorphic rocks that have undergone changes due to pressure and temperature.

Abstract

This study investigates the effectiveness of ecological management in supporting reclamation of tailings land at the Mile Post 21 Reclamation and Biodiversity Research Center, PT Freeport Indonesia. Using a qualitative descriptive approach, the research employs primary data obtained through interviews, documentation, and direct observation, complemented by secondary data from archives, reports, and company records. The analysis is guided by ISO 14001 environmental management principles, using a checklist method adapted from the Global Environmental Management Initiative (GEMI) to evaluate ecological, technical, socio-economic, and regulatory aspects of reclamation practices. Findings reveal that ecological management at Mile Post 21 has been highly effective, achieving more than 80% compliance with ISO 14001 indicators. Vegetation cover increased from less than 10% to over 75%, with more than 160 planted species complemented by natural succession involving over 500 species. Soil quality improved significantly, with organic carbon rising from <0.5% to 2.5%, pH levels increasing toward neutrality, and cation exchange capacity reaching medium–high levels. These changes facilitated the restoration of ecological functions and supported biodiversity recovery. Moreover, reclaimed land has been transformed into productive agricultural areas integrating crops, livestock, and aquaculture, providing socio-economic benefits for local communities and involving indigenous landowners in sustainable management. Despite technical challenges related to poor soil properties and managerial constraints such as long-term funding, the program demonstrates that ecological management, when implemented systematically under ISO 14001, can effectively restore degraded post-mining land into ecologically resilient and socially beneficial systems.

Abstract

Coastal abrasion poses a significant threat to Indonesia, an archipelagic nation with one of the world’s longest coastlines. The phenomenon is particularly severe in Napabalano District, Muna Regency, where dense settlements, economic activities, and declining mangrove ecosystems increase exposure to erosion hazards. This study aims to assess the risk of coastal abrasion in Napabalano District using a GIS-based approach aligned with the Indonesian National Disaster Management Authority (BNPB) framework. Primary data, including GPS coordinates, satellite imagery, and field surveys, were integrated with secondary data such as demographic statistics, oceanographic parameters, and historical records of abrasion events. Spatial analysis in ArcGIS was employed to evaluate vulnerability, capacity, hazard, and disaster risk indices. Results show that all villages in Napabalano District fall into the high-risk category, with Napabalano and Napalakura recording the highest risk values due to concentrated populations, limited mangrove protection, and inadequate disaster management capacity. Social and economic vulnerabilities, including high poverty ratios and dependence on coastal livelihoods, exacerbate exposure, while institutional capacity remains critically low, marked by weak early warning systems and limited community preparedness. Mitigation strategies proposed include mangrove rehabilitation, strict coastal zoning enforcement, community-based disaster preparedness programs, and the establishment of effective early warning systems. These findings highlight the urgent need for integrated, multi-stakeholder approaches to strengthen resilience against coastal abrasion. The study provides a strategic basis for local government and community planning in managing and reducing the impacts of coastal hazards in Napabalano District.

Abstract

The rapid growth of road infrastructure in Indonesia has increased the demand of construction materials and at the same time, intensified environmental issues. The study explores the potential application of nickel waste- which is a byproduct readily available to Indonesia in the smelting of nickel- as a partial replacement to coarse aggregate in porous asphalt mixtures. The research not only assesses the technical performance but also the environmental impact of the nickel waste substitution which can be regarded as a contribution to the literature on sustainable management of the construction process and the circular economy. Key parameters such as stability, flow, void content and the Marshall Quotient were tested in the laboratory and were evaluated as per the Bina Marga and SNI requirements. The results refer to the fact that nickel waste may meet a number of technical requirements, reaching an ideal concentration of asphalt into 5.5 0-100 that, at the same time, can provide waste minimization and possible cost-saving benefits. However, due to the fact that nickel slag contains heavy metals, it requires the use of strong environmental risk management, such as leaching control and stabilization technologies. These findings indicate that the use of nickel waste is more than a technical innovation; it is a strategic direction of the ability to become resource-efficient, symbiotic in the industrial industry, and to govern the operation of infrastructure in a sustainable manner. Placing industrial waste in a new category as productive input, this research sheds some light on how policy can be changed, how to innovate in procurements, and how government, industry, and academia can collaborate. The study concludes that the addition of nickel waste to the porous asphalt mixtures could help improve the performance of roads, reduce environmental ecological impacts, and promote the green infrastructure agenda in Indonesia, assuming that there are regulatory protections and a systematic environmental check-up.
