Abstract

This study aims to evaluate reclamation activities on the post-mining land of PT Bumi Sentosa Jaya in Boedingi Village, Lasolo District, North Konawe Regency, Southeast Sulawesi Province. Mining activities carried out in the area have caused environmental degradation, particularly in soil quality and vegetation. Therefore, reclamation activities, including revegetation, need to be carried out to restore the ecological function of the land. This study uses the Normalized Difference Vegetation Index (NDVI) analysis method to evaluate the success rate of revegetation as an indicator of vegetation health and density. In addition, an analysis was conducted on the reclamation plan and the estimated costs required. The data used in this study consisted of Sentinel-2 satellite images and drone photos to obtain an accurate picture of topographical changes and vegetation growth. The results showed that the reclamation activities carried out by PT Bumi Sentosa Jaya succeeded in increasing vegetation density in the reclaimed area. The area of land that has been reclaimed reached 11.90 ha in the period from 2023 to 2024, with the success of revegetation measurable through an increase in NDVI values. The reclamation plan, which includes land preparation, planting of cover crops and pioneer plants, and plant maintenance, has been implemented in accordance with established standards. This study is expected to contribute to the development of reclamation and revegetation techniques in mining areas, as well as provide recommendations for companies and policy makers to improve the success of future reclamation activities.

Abstract

growing rapidly and have the potential to put pressure on the hydrological system of the Watershed (DAS) and the dynamics of sedimentation in coastal areas. The applied open-pit mining system causes extensive land clearing and reduced vegetation cover, which can increase surface runoff and soil erosion. This study aims to analyze the spatial relationship between nickel mining land clearing, watershed hydrological response, and coastal sedimentation levels during the period 2016–2025. The data used are multi- temporal Sentinel-2 Level-2A satellite images analyzed using the Normalized Difference Vegetation Index (NDVI) to identify the condition of mining land clearing and the Normalized Difference Turbidity Index (NDTI) to represent the level of sedimentation and turbidity of coastal waters. Spatial analysis was carried out based on watershed units to examine the upstream–downstream relationship between the intensity of mining land clearing and sedimentation responses in the estuarine zone. The results show that watersheds with a dominant low NDVI value tend to experience increased surface runoff and potential soil erosion, which in turn contributes to increased coastal sedimentation as indicated by relatively high NDTI values. These findings confirm a strong link between land cover changes due to nickel mining activities, watershed hydrological responses, and coastal sedimentation intensity. This research emphasizes the importance of a watershed-based approach in nickel mining environmental management and sedimentation impact mitigation efforts to maintain the sustainability of coastal ecosystems.

Abstract

Permasalahan sampah rumah tangga masih menjadi isu penting di kawasan perkotaan, termasuk di Kelurahan Borong, Kecamatan Manggala, Kota Makassar. Kelurahan Borong merupakan salah satu wilayah administrasi di Kecamatan Manggala yang tercatat memiliki 65 RT dan 12 RW, sehingga aktivitas rumah tangga masyarakat berpotensi menghasilkan sampah domestik dalam jumlah cukup besar. Urgensi kegiatan ini juga didukung oleh Satu Data Kota Makassar yang mencatat timbulan sampah harian Kecamatan Manggala pada tahun 2024 sebesar 116,52 ton per hari Daga, R., Haya, R., Agriyani, D., & Suyuti, N. F. (2025).. Kondisi tersebut menunjukkan perlunya edukasi dan pendampingan masyarakat dalam pengelolaan sampah berbasis sumber agar tidak seluruh sampah rumah tangga berakhir di tempat pembuangan akhir. Kegiatan Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan pengetahuan, kesadaran, dan keterampilan warga Kelurahan Borong dalam menerapkan pengelolaan sampah terpadu limbah rumah tangga. Metode kegiatan dilakukan melalui sosialisasi, penyuluhan, diskusi partisipatif, demonstrasi pemilahan sampah, serta praktik sederhana pengolahan sampah organik dan anorganik. Daga, R. (2021) jenis sampah, pemilahan sampah dari sumber, penerapan prinsip 3R yaitu reduce, reuse, recycle, pengolahan sampah organik menjadi kompos, serta pemanfaatan sampah anorganik yang masih memiliki nilai guna dan nilai ekonomi. Prinsip 3R sejalan dengan pendekatan pengelolaan sampah ramah lingkungan yang menekankan pengurangan, penggunaan kembali, dan pendaurulangan sampah. Hasil kegiatan menunjukkan bahwa masyarakat mulai memahami pentingnya pemilahan sampah sejak dari rumah tangga sebagai tahap awal pengelolaan sampah terpadu. Peserta kegiatan memperoleh pemahaman bahwa sampah organik, seperti sisa makanan dan daun kering, dapat diolah menjadi kompos, sedangkan sampah anorganik, seperti botol plastik, kardus, dan kemasan bekas, dapat dipilah untuk dimanfaatkan kembali atau disalurkan melalui mekanisme bank sampah. Kegiatan ini juga mendorong perubahan cara pandang masyarakat bahwa sampah bukan hanya limbah yang harus dibuang, tetapi juga sumber daya yang dapat dikelola secara produktif apabila dilakukan secara sistematis dan berkelanjutan. Dengan demikian, pengelolaan sampah terpadu limbah rumah tangga di Kelurahan Borong Kota Makassar dapat menjadi strategi pemberdayaan masyarakat dalam mendukung kebersihan lingkungan, pengurangan timbulan sampah, dan peningkatan kesadaran ekologis warga. Program ini perlu dilanjutkan melalui pendampingan berkala, pembentukan kelompok pengelola sampah, penguatan bank sampah, serta kerja sama antara masyarakat, pemerintah kelurahan, dan instansi lingkungan hidup. Penguatan kelembagaan pengelolaan sampah juga sejalan dengan ketentuan nasional bahwa pengelolaan sampah harus dilakukan secara sistematis, menyeluruh, dan berkesinambungan, termasuk melalui peran masyarakat dan pengelolaan bank sampah.

Abstract

Wastewater management domestic is aspect crucial in control pollution environment. especially in developing areas like Merauke Regency. Research This aim evaluate performance Installation Domestic Wastewater Treatment Plant ( WWTP) in Housing District Ulilin in fulfil standard quality Minister of Environment and Forestry Regulation No. 11 of 2025. Research method use approach quantitative descriptive – evaluative with design studies case. Taking sample carried out at the inlet and outlet of the IPAL during September–October 2025 using grab sampling method. with Analysis of TSS, pH, BOD₅, COD, oil and fat, NH₃-N, and total coliform parameters based on Standard Methods (APHA, 2017). The results show that characteristics influence majority exceed standard quality. especially in the parameters BOD₅ (33.4 mg/L), COD (122.5 mg/L), TSS (35.5 mg/L), oil and fat (6.15 mg/L), NH₃-N (13.1 mg/L), and total coliform (3.59×10³ MPN/100 mL). After processing. all effluent parameters fulfil standard quality with level 100% compliance Efficiency elimination show very good performance. with decline significant on BOD₅ (83.38%), COD (84.04%), TSS (49.30%), and NH₃-N (93.13%). High safety margin to standard quality show system own capacity adequate and resilient reserves to fluctuations burden polluters. In overall. domestic wastewater treatment plant District Ulilin operate effective. stable. and feasible in support protection quality environment in a way sustainabl.
