Pertumbuhan Jabon Merah, Jabon, dan Sengon Buto di Lahan Bekas Tambang Batubara PT. Tunas Inti Abadi, Kalimantan Selatan

Abstract

Mined land reclamation are important in restoring environmental conditions such as baseline prior to mining activites. The purpose of this research is to look effect manure dose given to each planting hole on jabon merah (Anthocepalus macrophyllus), jabon (Anthocepalus cadamba) and sengon buto (Enterelobium cylocarpum) and to compare the best growth of all three species of plants. The research was conducted on mined lands of PT. Tunas Inti Abadi, South Kalimantan. Experimental design used in this research was completely randomized design (CRD) factorial, with factors are spesies and dose of manure. Parameters used to look the growth of plant is height and diameter. Result showed that the dose of manure significantly affected diameter growth, but did not significantly affect plant height growth. Highest diameter growth was made by sengon buto. Spesies did not significantly affect diameter, but they showed significant differences on height growth rate. Sengon buto is the fastest growing species in term of height. Interaction between the dose of manure to species of plant affect only on diameter. The best species among the three spesies itested was sengon buto.
