      Abstract
      Pertumbuhan jabon (Anthocephalus cadamba) pada lahan bekas tambang tidak optimal dikarenakan tanah masam dan unsur hara yang sangat rendah. Pengapuran dan Lubang Resapan Biopori merupakan upaya dalam peningkatan pertumbuhan jabon. Kapur dapat menetralkan asam dan Lubang Resapan Biobori (LRB) dapat memperluas permukaan tanah dalam meresapkan air hujan, selain itu serasah dalam LRB dapat menambah unsur hara. Tujuan penelitian ini yaitu meningkatkan pertumbuhan jabon melalui pembuatan LRB serta mengetahui jenis isian LRB yang terbaik dari daun tumbuhan LCC (Legume Cover Crops), daun akasia (Acacia mangium), atau sampah dapur organik. Daun LCC merupakan serasah isian terbaik berdasarkan variabel diameter karena memiliki rataan tertinggi dan berbeda nyata dengan perlakuan P2 (LRB berisi daun akasia) dan P0 (kontrol). Sampah dapur (P3) merupakan serasah isian LRB terbaik berdasarkan parameter tinggi karena berbeda nyata dengan kontrol (P0) dan memiliki rataan tertinggi.
       
      Growth of jabon (Anthocephalus cadamba) on postmining area is not optimal due to the acidic soil and nutrients are very low. Liming and Hole Infiltration of Biopori was an effort to improve Jabon growth. Lime can neutralize acid and Hole Infiltration of Biopori (LRB) can expand the ground to absorb water in the rain, in addition to the litter in the LRB can add nutrients. The purpose of this research is to improve jabon growth through making LRB and know the best of the LCC (Legume Cover Crops) plant leaves, leaf of Acacia mangium, or organic kitchen waste for LRB. Leaf litter stuffing LCC is best based on the variable diameter because it has the highest average and significantly different from treatment P2 (LRB containing acacia leaf) and P0 (control). Kitchen waste (P3) is the best litter LRB field parameters based high as significantly different from the control (P0) and has the highest average.
