Kegiatan reklamasi lahan bekas tamb

Kegiatan reklamasi lahan bekas tambang sering mengalami kendala seperti pH tanah yang rendah, pemadatan tanah, kandungan unsur hara yang rendah dan mengandung bahan-bahan beracun pada tanah. Perbaikan kualitas tanah perlu dilakukan untuk menunjang keberhasilan reklamasi. Perbaikan kualitas tanah dapat dilakukan dengan cara menambahkan bio soil booster pada tanah tersebut. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian bio soil booster pada tanah lahan bekas tambang batubara dengan tanaman sorgum (Sorghum bicolor Linn.) sebagai indikator kualitas tanah. Bio soil booster yang digunakan terdiri dari empat tingkat konsentrasi yaitu kontrol (0%), konsentrasi tinggi (0,4%), konsentrasi sedang (0,2%), dan konsentrasi rendah (0,1%). Sampel tanah yang digunakan terdiri dari sampel tanah normal (media tanam A) dan lima sampel tanah lahan bekas tambang batubara (media tanam B, C, D, E, dan F). Respon S. bicolor yang diamati adalah pertambahan tinggi, pertambahan panjang akar, performa akar, dan performa daun. Hasil pengamatan menunjukan bahwa pemberian bio soil booster pada lahan bekas tambang dapat meningkatkan kualitas tanah. Larutan bio soil booster dengan konsentrasi tinggi (0,4 %) dan sedang (0,2 %) efektif digunakan pada media tanah B, D, E, dan F.

Land reclamation activities of the former mines often experience barriers such as the low soil pH, soil compaction, low nutrient content and contain toxic materials on the ground. Improvement of soil quality needs to be done to support the success of reclamation. Improvement of soil quality can be done by adding bio booster on the ground soil. This research aims to know the influence of soil bio booster on granting the land ex coal mining with plants sorghum (Sorghum bicolor Linn.) as an indicator of soil quality. Bio soil booster used consisted of four levels of concentrations, namely the control (0%), high concentration (0.4 percent), moderate concentrations (0.2%), and low concentrations (0,1%). Soil sample used consists of normal soil samples (A planting medium) and five soil samples ex coal mining (the planting medium B, C, D, E, and F). The response of s. bicolor observed high added value, is the length of the root, the root, the performance and the performance of the leaves. The observations showed that the granting of bio soil booster on land mines can improve soil quality. Bio booster soil solution with a high concentration (0.4%) and moderate (0.2%) were effectively used in media land of B, D, E, and F.

Mined land reclamation activities often encounter obstacles such as low soil pH, soil compaction, low nutrient content and contain toxic materials in the soil. Improvement in the quality of land is needed to support the success of reclamation. Soil quality improvement can be done by adding a soil bio booster on the ground. This study aimed to determine the effect of soil bio booster on coal mined land soil with sorghum (Sorghum bicolor Linn.) As an indicator of soil quality. Bio soil booster used consisted of four levels of concentration, control (0%), a high concentration (0.4%), moderate concentration (0.2%), and low concentration (0.1%). Soil samples used consisted of a sample of normal soil (growing medium A) and five soil samples of coal mined land (planting medium B, C, D, E, and F). S. bicolor response is observed as height, the length of roots, root performance, and the performance leaves. The observations showed that administration of soil bio booster on mined land can improve soil quality. Soil bio booster solution with a high concentration (0.4%) and moderate (0.2%) effectively used in soil medium B, D, E, and F.
