Ecological Evaluation and Development of Reclamation Model of Post Tin Mining Land in Bangka Island
Penambangan timah yang telah berlangsung lama di Pulau Bangka, telah berdampak negatif terhadap lingkungan hidup. Penelitian ini bertujuan mengevaluasi struktur dan fungsi ekosistem lahan pascatambang timah di Bangka dan mengembangkan model reklamasi yang tepat berdasarkan hasil evaluasi ekologis terhadap lahan tersebut. Metode evaluasi kondisi ekologis terdiri dari penentuan lokasi, pengukuran mikroklimat, pengukuran karakteristik tanah, Ecosystem Function Analysis (EFA) yang meliputi Landscape Function Analysis (LFA), analisis vegetasi, dan analisis kompleksitas habitat, dilakukan pada tiga jenis lahan, yaitu lahan pascatambang yang belum direklamasi (A), lahan pascatambang yang telah direklamasi (B), dan hutan alami (C) sebagai reference site. Setelah itu, dilakukan eksperimen revegetasi terdiri dari perlakuan perubahan pada tanah, meliputi kontrol, ripping, ripping + kompos; dan rezim revegetasi spontan dan penanaman.
Rehabilitation of Ex-Mining Quarry Area
Several phosphate (P) and sodium (K) solubilizing bacteria, nitrogen fixing bacteria, and indole-3- acetic acid (IAA) producing bacteria isolates have been isolated from soil in mining limestone Cirebon. These bacteria were selected, blended, and packaged together into biological fertilizer product. The use of biological fertilizers on seedling plants could replace synthetic chemical fertilizers on seedling plants. Phosphate and potassium solubilizing bacteria have the ability to produce a substance that dissolves the compound P and K bound contained in the soil, so that it becomes available to plants and can replace synthetic fertilizers (chemical) P and K. Nitrogen-fixing bacteria ( N) can reduce the use of urea fertilizer. Several bacteria also produce indole-3-acetic acid known as auxin, one of growth promoting hormone. The basic philosophy underlying this research project is to rehabilitate sandy clay at ex-mining area based on new technology and low capital expenditure. The experiments conducted were (1) use of bacterial formulation consist of P and K solubilizing bacteria, N fixing bacteria, IAA producing bacteria as biofertilizer for seedling plant that planted in ex-mining land in Hambalang, (2) re-vegetation on ex-mining area by using phytoremediation plants such as leucaena (Leucaena leucocephala), albizia (Albizia saman), and pterocarpus (Pterocarpus indicus) application with compost and consortium of bacteria on ripping and without ripping soil treatments, and (3) evaluation of ecological condition on ex-mining area.
EVALUATION OF ECOLOGICAL FUNCTION AND REVEGETATION LEVEL OF POST TIN MINING LAND
Tin mining that has lasted long in Belitung, had a negative impact on the environment. This research objectives was to evaluate the ecological condition and do revegetation experiment to know revegetationlevel of tin post-mining in Air Mungkui, Belitung District. The method of evaluating the ecological condition, consisted of the location positioning, measuring microclimates, soil characteristics measurement, Ecosystem Function Analysis (EFA) which included Landscape Function Analysis (LFA), analysis of vegetation, and habitat complexity analysis, performed on three types of land, i.e. the post-mining land that hasn’t been reclaimed (A), post-mining land that has been reclaimed (B), and natural forests (C) as the reference site. Revegetation experiment consisted of treatment changes on the ground, that consisted of control, ripping, ripping + compost treatment and spontaneous revegetation and planting regimes.
