Analisis Tingkat Keberhasilan Reklamasi Lahan Pasca Tambang Nikel di Kabupaten Luwu Timur = THE ANALYSIS OF RECLAMATION SUCCESS RATE ON POST-NICKEL MINING LAND IN EAST LUWU REGENCY

ABSTRAK Adrian Kombong. Analisis Tingkat Keberhasilan Reklamasi di Lahan Pasca Tambang Nikel Di Kabupaten Luwu Timur (dibimbing oleh Mukrimin Muke dan Syamsuddin Millang). Latar Belakang: Kabupaten Luwu Timur, Sulawesi Selatan, memiliki cadangan nikel besar sekaligus kawasan hutan terluas di provinsi ini, sehingga aktivitas pertambangan berlangsung intensif. Untuk menjaga kelestarian lingkungan, perusahaan tambang wajib melaksanakan reklamasi pascatambang. Penilaian keberhasilan reklamasi oleh pemerintah mencakup tiga aspek utama, yaitu penataan lahan, pengendalian erosi, dan revegetasi, dengan bobot terbesar pada revegetasi. Namun, fokus yang berlebihan pada revegetasi tanpa didukung penataan lahan dan pengendalian erosi yang baik sering menyebabkan reklamasi gagal mencapai fungsi ekologisnya.Metode: Penelitian ini menganalisis pengaruh penataan lahan dan pengendalian erosi terhadap keberhasilan revegetasi pada dua perusahaan tambang di Kabupaten Luwu Timur. Pengumpulan data dilakukan melalui survei lapangan terhadap parameter utama reklamasi, meliputi penutupan lubang bekas tambang, kestabilan lereng, tanah pucuk, bangunan pengendali erosi, serta persentase tumbuh dan kesehatan tanaman. Hasil pengamatan divalidasi melalui sistem skor berbobot sesuai regulasi penilaian reklamasi.Hasil:Hasil penelitian menunjukkan bahwa penataan lahan dan pengendalian erosi yang optimal berkontribusi signifikan terhadap keberhasilan revegetasi. Persentase tumbuh dan kesehatan tanaman meningkat seiring dengan kondisi lahan yang stabil dan terkontrol dari erosi. Dengan demikian, integrasi ketiga aspek tersebut menjadi kunci utama keberhasilan reklamasi pascatambang di Kabupaten Luwu Timur. ABSTRACT Adrian Kombong. The Analysis Of Reclamation Success Rate on Post-Nickel Mining Land In East Luwu Regency (Supervised by Mukrimin and Syamsuddin Millang). Background: East Luwu Regency, South Sulawesi, possesses large nickel reserves and the widest forest area in the province, resulting in intensive mining activities. To maintain environmental sustainability, mining companies are required to carry out post-mining reclamation. The government’s reclamation success assessment includes three main aspects: land arrangement, erosion control, and revegetation, with the highest weight given to revegetation. However, excessive focus on revegetation without proper land preparation and erosion control often leads to reclamation failure in restoring ecological functions. Method: This study analyzes the influence of land arrangement and erosion control on revegetation success in two mining companies located in East Luwu Regency. Data were collected through field surveys measuring key reclamation parameters, including backfilling of mining pits, slope stability, topsoil management, erosion control structures, as well as plant growth percentage and health conditions. The observations were validated using a weighted scoring system based on official reclamation assessment regulations. Results: The results show that optimal land arrangement and erosion control significantly contribute to the success of revegetation. The percentage of plant growth and health improved along with stable land conditions and controlled erosion. Therefore, the integration of these three aspects becomes the key factor in achieving successful post-mining reclamation in East Luwu Regency. Keywords: Land arrangement, Erosion control, Reclamation, Revegetation
