Abstract
PT. Amman Mineral Nusa Tenggara, located in Sekongkang District,
Sumbawa Regency, West Nusa Tenggara Province, is one of the companies
engaged in the mining of copper and gold ore. Mining activities often cause
environmental damage, resulting in a decrease in environmental quality,
therefore PT Amman Mineral Nusa Tenggara carries out reclamation activities
carried out throughout the Mining Business stage to organize, restore, and
improve the quality of the environment and ecosystem so that it can function
again according to its designation. The purpose of this study was to determine the
implementation of the reclamation stages, determine the criteria for the success of
reclamation and the percentage of success of the reclamation that has been
determined. The implementation of the reclamation stages carried out by PT
Amman Mineral Nusa Tenggara is land preparation, distribution of reclaimed
land, soil compaction, soil density analysis, and revegetation, and post-mining
carried out is land and plant maintenance, and vegetation monitoring, while the
reclamation success criteria obtained are criteria cover cropping, erosion
incidence, planting plan, growth percentage, number of plants per hectare,
species composition, and plant health. Based on the reclamation success criteria
obtained, the percentage value obtained for each success criterion is cover by
cover crop 90% cover by cover crop, erosion incidence 5% compared to the total
area of reclamation, planting plan 90% compared to plan, percentage grows 90%
of the number of trees planted, the number of plants per hectare that grows at
least 625 plants, local plant species is ≥ 40%, Plants that grow well at least 90%
of the total number of trees planted = PT. Amman Mineral Nusa Tenggara berlokasi di Kecamatan Sekongkang,
Kabupaten Sumbawa, Provinsi Nusa Tenggara Barat merupakan salah satu
perusahaan yang bergerak dalam bidang penambangan bijih tembaga dan emas.
Kegiatan penambangan seringkali menyebabkan kerusakan lingkungan, sehingga
menyebabkan penurunan mutu lingkungan, maka dari itu PT Amman Mineral
Nusa Tenggara melakukan kegiatan reklamasi yang dilakukan sepanjang tahapan
Usaha Pertambangan untuk menata, memulihkan, dan memperbaiki kualitas
lingkungan dan ekosistem agar dapat berfungsi kembali sesuai peruntukannya.
Tujuan penelitian ini adalah untuk mengetahui pelaksanaan tahapan reklamasi,
mengetahui kriteria keberhasilan reklamasi serta presentase keberhasilan dari
reklamasi yang telah ditentukan. Pelaksanaan tahapan reklamasi yang dilakukan
PT Amman Mineral Nusa Tenggara adalah penyiapan lahan, penebaran tanah
reklamasi, pemadatan tanah, analisis kepadatan tanah, dan revegetasi, dan
pascatambang yang dilakukan adalah pemeliharaan lahan dan tanaman, serta
pemantauan vegetasi, sedangkan kriteria keberhasilan reklamasi yang didapatkan
adalah kriteria penutupan oleh tanaman penutup tanah (covercrop), kejadian erosi,
rencana penanaman, persentase tumbuh, jumlah tanaman per hektar, komposisi
jenis, dan kesehatan tanaman. Berdasarkan kriteria keberhasilan reklamasi yang
didapatkan maka nilai persentase yang didapatkan setiap kriteria keberhasilan
adalah penutupan oleh tanaman penutup tanah (covercrop) ≥ 90% penutupan oleh
covercrop, kejadian erosi ≤ 5% dibanding luas total daerah reklamasi, rencana
penanaman ≥ 90% dibanding rencana, persentase tumbuh ≥ 90% dari jumlah
pohon yang ditanam, jumlah tanaman per hektar yang tumbuh minimal 625
tanaman, jenis tanaman lokal adalah ≥ 40%, Tanaman yang tumbuh dengan baik
minimal 90% dari total jumlah pohon yang ditanam.
