Respon Pertumbuhan Jabon (Anthocephalus cadamba (Roxb.) Miq.) Terhadap Lubang Resapan Biopori pada Lahan Bekas Tambang

Abstract

Growth of jabon (Anthocephalus cadamba) on postmining area is not optimal due to the acidic soil and very low nutrients content. 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 during the rain. In addition to the litter in the LRB able to improve soil nutrients. The purpose of this research was to improve jabon growth through LRB and to know the best of the LCC (Legume Cover Crops) plant leaves, leaf of Acacia mangium, or organic kitchen waste for LRB. LCC Leaf litter was reached best results based on the diameter due to having rata-rata highest and significantly different part with treatment P2 (LRB containing acacia leaf) and P0 (control). Kitchen waste (P3) is litter stuffing in the best LRB based on parameters high because significantly different with control (P0) and has the highest average. Key words: hole infiltration of biopori, jabon, LCC leaf, liming, kitchen waste
