The Effect of Plant Growth Ameliorant Against Pioneers in the Land of Used Media Coal Mine in the Nursery
Anis Tatik Maryani, Sarman
Abstract: Open pit mining activities can have negative impacts on the environment. The impact of mining activities of which are topsoil disappearance, soil compaction and nutrient imbalance. The soil will cause the plant revegetation difficult to survive on mined land. This study aims to determine the growth of tree seedlings (a) sengon, (b) Trembesi, (c) Jabon tree, (d) mahogany, (e) ketapang, and (f) Agarwood, the former land of coal mines being treated ameliorant form of manure goat and rice husk as pembenah soil. the treatments were 50 % of the land of the former coal mine + 25 % + 25 % goat manure husk. After the treatment given to each of the planting medium, the medium is incubated for 15 days. the analysis includes the initial soil pH, macro nutrients (N, P, K). After completion of incubation, the media planted tree seedlings (a) sengon, (b) Trembesi, (c) Jabon tree, (d) mahogany, (e) ketapang, and (f) Agarwood age 1 month. the variables observed Percentage of life, stem deformation, deformation of roots, stems robustness and compactness roots. Observations show on the observation of 12 weeks after the treatment produces an average percentage of 99.17 % life, Deformation straight rods on the criterion of 90 %, Deformation criteria roots straight 80 %, while 85 %. The robustness stems and roots compactness of 100 %. Thus giving treatment ameliorant form of goat manure and rice husk as soil quality improvement mixed into the former coal mine land can be developed as a replacement of top soil on the rehabilitation of former coal mining laban.
