Abstract
ABSTRACT This research activity was conducted in coal mining land at West Banko pit 1 east and pit 3 east PT. Bukit Asam (Persero), Tbk. Lawang Kidul sub-district, Muara Enim district, South Sumatra province. The coal mining activities in this area can potentially change its physical environment such as top soil lose, biodiversity degradation, land erosion and drought. The aim of this research is to recognize the land condition after revegetation and the success rate of revegetation activities at West Banko Pit 1East and Pit 3 East, PT. Bukit Asam (Persero), Tbk. The methods applied in this research are field survey with purpossive sampling technique, land observation and laboratory analysis. The parameters in this research are slope, effective soil depth, soil fertility (C organic), land cover vegetation and plant health. The technique conducted to evaluate the data is scoring method in which 5 parameters are measured. The purpose of this method is to know the land condition after reclamation and the success rate of revegetation in the research area. Based on this research, the revegetation in West Banko pit 1 East has been done with pioneer revegetation plant age 2 years, slope condition 2,2% -16,66%, effective soil depth 71 – 153 cm, soil fertility 2,73% – 3,82%, land vegetation cover 43,3% - 62,3%, and plant health 90,47% - 96,10%. The success criteria of revegetation is rated good at plot 2, while plot 1 dan 3 are rated moderate. On the other side, the revegetation activity in West Banko Pit 3 East has been done with pioneer revegetation plant age 3 years, with 3,33%-16,66% in slope, 74 – 126 cm in soil depth, 2,21% – 2,94% in soil fertility, 38% - 50,6% in land vegetation cover and 84,31% - 87,5% in plant health. The success criteria of revegetation is rated good at plot 1, 2 dan 3 while plot 4 is rated moderate. Keyword: Coal, Reclamation, Revegetation, Coal Mine, Post Mine Reclamation INTISARI Kegiatan penelitian ini dilaksanakan pada lokasi tambang batubara Banko Barat Pit 1 Timur dan Pit 3 Timur, PT. Bukit Asam (Persero), Tbk, Kecamatan Lawang Kidul, Kabupaten Muara Enim, Provinsi Sumatra Selatan. Kegiatan penambangan batubara pada lokasi tersebut berpotensi menimbulkan perubahan lingkungan fisik lahan seperti hilangnya tanah pucuk (top soil), berkurangnya keanekaragaman hayati, terjadinya erosi, serta tanah menjadi gersang dan tandus. Tujuan dari penelitian ini adalah untuk mengetahui kondisi lahan revegetasi dan tingkat keberhasilan revegetasi di lahan reklamasi tambang batubara Banko Barat Pit 1 Timur dan Pit 3 Timur, PT. Bukit Asam (Persero), Tbk. Metode penelitian yang digunakan yaitu survey lapangan dengan teknik puposive sampling, pengamatan lapangan, dan analisis laboratorium. Parameter yang digunakan dalam penelitian ini yaitu kemiringan lereng, kedalaman efektif tanah, C organik tanah, tutupan vegetasi lahan, dan kesehatan tanaman. Teknik evaluasi data menggunakan metode skoring atau pengharkatan terhadap 5 parameter yang diteliti, sehingga dapat diketahui kondisi lahan revegetasi serta tingkat keberhasilan revegetasi pada lokasi penelitian. Berdasarkan hasil penelitian yang dilakukan, diketahui bahwa kondisi lahan revegetasi tambang Banko Barat lokasi Pit 1 Timur telah dilakukan revegetasi dengan jenis tanaman revegetasi pioneer dan umur tanaman 2 tahun, dengan kondisi kemiringan lereng 2,2% -16,66%, kedalaman efektif tanah 71 – 153 cm, kesuburan tanah 2,73% – 3,82%, penutupan vegetasi lahan 43,3% - 62,3%, dan kesehatan tanaman 90,47% - 96,10%, dengan tingkat keberhasilan revegetasi baik pada plot 2, sedangkan pada plot 1 dan 3 memiliki kriteria keberhasilan revegetasi yang sedang. Sedangkan kondisi lahan revegetasi tambang Banko Barat lokasi Pit 3 Timur telah dilakukan revegetasi dengan jenis tanaman revegetasi pioneer dan umur tanaman 3 tahun, dengan kondisi kemiringan lereng 3,33%-16,66%, kedalaman efektif tanah 74 – 126 cm, C organik tanah 2,21% – 2,94%, penutupan vegetasi lahan 38% - 50,6%, dan kesehatan tanaman 84,31% - 87,5%, dengan tingkat keberhasilan revegetasi baik pada plot 1, 2 dan 3, serta keberhasilan sedang pada plot 4.
