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.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilaksanakan di Desa Totobo, Kecamatan Pomalaa, Kabupaten Kolaka, dengan tujuan meningkatkan pengetahuan dan keterampilan masyarakat dalam memanfaatkan lahan pekarangan sebagai kebun Tanaman Obat Keluarga (TOGA). Program ini merupakan bentuk pemberdayaan masyarakat berbasis transfer pengetahuan melalui pendekatan edukatif dan praktik langsung. Kegiatan dilaksanakan dengan melibatkan kelompok ibu-ibu PKK dan pemuda desa, yang dibekali pengetahuan tentang jenis tanaman obat, manfaat farmakologis, serta teknik budidaya yang sederhana dan ramah lingkungan. Pelatihan meliputi tahap sosialisasi, pembuatan bedengan, penanaman bibit, serta pemeliharaan tanaman secara mandiri. Hasil kegiatan menunjukkan peningkatan signifikan dalam tingkat pengetahuan peserta, dari 35% sebelum pelatihan menjadi 85% setelah pelatihan. Peserta juga menunjukkan kreativitas tinggi dengan memanfaatkan bahan daur ulang sebagai wadah tanam. Selain meningkatkan kemandirian kesehatan keluarga, program ini berdampak pada aspek sosial dan ekonomi melalui pembentukan kelompok TOGA Mandiri Desa Totobo serta pengembangan produk herbal rumah tangga. Secara keseluruhan, kegiatan ini berhasil mendorong partisipasi aktif masyarakat dalam pemanfaatan sumber daya lokal untuk mendukung kesehatan, pelestarian lingkungan, dan pemberdayaan ekonomi berbasis kearifan lokal.
