Abstract
Karakteristik lahan bekas tambang batubara yang paling menonjol adalah lahan yang rusak berat sehingga menyebabkan menurunnya produktivitas tanah, erosi dan sedimentasi, terjadinya pergerakan tanah dan mengakibatkan longsor, serta pemadatan tanah sehingga sukar diolah. Upaya untuk memperbaiki sifat fisik tanah reklamasi tambang batubara yaitu dengan penambahan biochar dan kompos. Biochar dan kompos dapat memperbaiki sifat fisik tanah dengan meningkatkan kandungan bahan organik, total ruang pori, kadar air dan menurunkan bobot volume tanah. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 4 ulangan. Adapun perlakuan yang digunakan dalam penelitian ini yaitu b0 = tanpa perlakuan (kontrol); b1 = 15 ton/ha biochar cangkang kelapa sawit; b2 = 10 ton/ha biochar cangkang kelapa sawit + 5 ton/ha kompos sampah kota; b3 = 7.5 ton/ha biochar cangkang kelapa sawit + 7.5 ton/ha kompos sampah kota; b4 = 5 ton/ha biochar cangkang kelapa sawit + 10 ton/ha kompos sampah kota; b5 = 15 ton/ha kompos sampah kota. Variabel yang diamati yaitu kandungan bahan organik, bobot volume tanah, total ruang pori, kadar air tanah pada beberapa nilai pF, tinggi tanaman, hasil tanaman dan jumlah polong tanaman. Hasil penelitian diperoleh bahwa kombinasi perlakuan 7,5 ton/ha biochar cangkang kelapa sawit + 7,5 ton/ha kompos sampah kota merupakan komposisi terbaik untuk memperbaiki kadar air tanah reklamasi tambang batubara. Selanjutnya pemberian 15 ton/ha kompos sampah kota sudah efektif meningkatkan hasil kedelai. Characteristics of the most prominent former coal mining land are severe damaged land, causing decreased soil productivity, erosion and sedimentation, soil movement and resulting in landslides, and soil compaction so that it is difficult to process. Efforts to improve the physical properties of coal mining reclamation soils, namely by adding biochar and compost. Biochar and compost can improve the physical properties of the soil by increasing the content of organic matter, total pore space, water content and reducing the weight of soil volume. This study uses a complete random design (RAL) with 6 treatments and 4 replications. The treatment used in this study is B0 without treatment (control); B1 15 tons/ha biochar oil palm shells; B2 10 tons/ha biochar palm oil shells 5 tons/ha of city waste compost; B3 7.5 tons/ha biochar oil palm shell 7.5 tons/ha of city waste compost; B4 5 tons/ha Biochar palm oil shell 10 tons/ha of city waste compost; B5 15 tons/ha of city waste compost. The observed variables are the content of organic matter, the weight of soil volume, total pore space, soil water content in several PF values, plant height, plant yields and the number of plant pods. The results obtained that the treatment combination of 7.5 tons/ha of biochar oil palm shells 7.5 tons/ha of city waste compost is the best composition to improve the groundwater content of coal mining reclamation. Furthermore, the provision of 15 tons/ha of city waste compost has effectively improved soybean yield.
