Abstract
Mining techniques carried out in Kalimantan generally use the open mining technique (open mining method) with the refill method (back patching method), discuss critical ways of covering vegetation, cover the speed of presentation of force on rainwater that hits directly soil surface, erosion, direct exposure to sunlight and soil compaction that results in the use of heavy equipment.This research aims to obtain ex-coal mining land that can be used for agricultural land and plantation land by reclaiming ex-coal mining land by providing biochar and planting mucuna type LCC plants, so that the land contains nutrients and good soil texture. so the kenaf plant growth process can grow well.The research was carried out for one year, in the former coal mining area of PT. Puspa Juwita, Muara Badak, Kutai Kartanegara as a place for planting kenaf plants using biochar and mucuna planting is expected to be an alternative choice because it is easy, cheap and effective. The design used in this study is a Completely Randomized Design in Factorial form where the first factor is biochar and the second factor is planting mucuna.The results showed that kenaf plants can grow well on post-mining coal land that has been given biochar and mukuna planting first. From the growth of stem diameter and height of kenaf plants the highest data was seen in the B5 (Biochar 100kg) treatment and the lowest in the B1 treatment (without treatment).
