STUDI PERTUMBUHAN TANAMAN PADA AREAL PASCA TAMBANG DATARAN TINGGI DI KALIMANTAN SELATAN

This research purposed to analyze the growth of the plants on post-mining land based on the different vegetation ages. The observation was conducted on post-mining area of PT. Antang Gunung Meratus (AGM) at South Hulu Sungai Regency, South Kalimantan. The data retrieval included high condition and diameter of the plants also the physical and chemical characteristics of soil on reclamation area which aged 1 year, 5 years, and 7 years. The dominant species which were in the research location was sengon, trembesi, and gmelina. The average of plants high age 1 year were sengon 1,99 m, trembesi 1,01 m, and gmelina 0,94 m. The average diameter 1 year plants were sengon 4,13 cm, trembesi 2,48 cm, and gmelina 2,70 cm. The average of plants high age 5 years were sengon 7,89 m, trembesi 7,94 m, and gmelina 8,04 m. The average of diameter 5 years plants were sengon 30,49 cm, trembesi 25,23 cm and gmelina 21,38 cm. The average of high growth and diameter of 7 years old sengon plants is 13,02 m, and is diameter 30,18 cmPenelitian ini bertujuan menganalisis pertumbuhan tanaman pada lahan pasca tambang berdasarkan umur vegetasi yang berbeda. Pengamatan dilakukan pada areal pasca tambang PT. Antang Gunung Meratus (AGM) Kabupaten Hulu Sungai Selatan Kalimantan Selatan. Pengambian data meliputi keadaan tinggi dan diameter tanaman serta sifat fisik dan kimia tanah pada lokasi reklamasi umur 1 tahun, 5 tahun, dan 7 tahun. Jenis yang dominan terdapat pada lokasi penelitian meliputi jenis sengon, trembesi dan gmelina. Rata-rata tinggi tanaman umur 1 tahun jenis sengon 1,99 m, trembesi 1,01 m dan gmelina 0,94, rata-rata diameter umur 1 tahun jenis sengon 4,13 cm, trembesi 2,84 cm dan gmelina 2,7 cm. Rata-rata tinggi tanaman umur 5 tahun jenis sengon 7,89 m, trembesi 7,94 m, dan gmelina 8,04 m. Rata-rata diameter tanaman umur 5 tahun jenis sengon 30,49 cm, trembesi 25,23 cm serta gmelina 21,38 cm. Rata-rata pertumbuhan tinggi serta diameter tanaman jenis sengon yang berumur 7 tahun memiliki rata-rata tinggi 13.02 m, dan rata-rata diameternya 30.18 cm
