Improving Quality of Kenaf Fibers (Hibiscus Cannabinus L.) on The Posted Coal Mining Point Using Biochar And Planting Mucuna) (Published)
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).

Improving Quality of Kenaf Fibers (Hibiscus Cannabinus L.) on the Posted Coal Mining Point Using Biochar and Planting Mucuna (Published)
Mining techniques undertaken in Borneo generally use open pit mining with back fillings method, causing critical land resulting from the loss of ground cover vegetation, the heavy pressure of the gravitational force on the rainwater that hit direct soil surface, erosion, direct exposure to sunlight and soil compaction caused by heavy equipment use. The objective of this research is to obtain ex-coal mining area that can be used for agricultural land and plantation land by reclamation of coal mine former land with biochar and planting of mucuna LCC species, so that the soil contains good nutrient and soil texture so that the growth process the kenaf plant can grow well. The research was carried out for one years, in the area of coal mining ex-field at PT. Puspa Juwita, Muara Badak, Kutai Kartanegara as a place of planting of kenaf plant by using biochardan mucuna planting is expected to be an alternative which become option because easy, cheap and effective. The design used in this research is Completely Randomized Design in Factorial form where the first factor is biochar and the second factor is mucuna planting. The results showed that the kenaf plant can grow well on post-mining land of coal that has been given biochar and mukuna planting first. From the highest stem diameter and height of the kenaf plant the highest was seen in the B5 treatment (Biochar 100kg) and the lowest in treatment B1 (without treatment)
