Post coal mining activities in the village of Tanah Datar Muara Badak District, East Kalimantan Province, left vast vacant land. One of efforts to utilize the post-mining land through experimentation with kenaf (Hibiscus cannabinus L.) plant. Kenaf is a stem-fiber producer from the Malvaceae family, and currently receiving industrial attention. Kenaf plant can be utilized entirely, as industrial raw material with high commercial value. Kenaf also environmental-friendly and can absorb carbon dioxide from the atmosphere, therefore it is suitable to be developed as environmental-friendly industrial raw material. Kenaf species can grow in land with low nutrient status and toxic chemicals. The results show that kenaf plant can grow well on post coal mine land that has been treated previously with biochar and fertilizer. Biochar 100 Kg per plot in dosage combining with Mucuna sp.that spacing 30 x 30 cm give the best result for Kenaf growth both in diameter and plant height.

Endo-rhizobakteri mampu menghasilkan hormon tumbuh, melarutkan fosfat dan memfiksasi nitrogen, yang berperan dalam perkecambahan dan perkembangan tanaman. Penelitian ini bertujuan untuk meningkatkan vigor benih padi gogo lokal yang diaplikasi konsorsium endo-rhizobakteri. Penelitian dilakukan di Laboratorium Agroteknologi Unit Agronomi Fakultas Pertanian Universitas Halu Oleo, Kendari pada bulan April 2018. Penelitian menggunakan rancangan acak lengkap, dengan 5 perlakuan yaitu: kontrol, isolat Be02 + PKLK, isolat Be02 + Bacillus sp. CKD061, isolat PKLK5 + Bacillus sp. CKD061 dan isolat Be02 + PKLK5 + Bacillus sp. CKD061. Setiap perlakuan diulang 3 kali sehingga diperoleh 15 unit percobaan. Pengamatan dilakukan terhadap daya berkecambah, potensi tumbuh maksimum, indeks vigor, keserempakkan tumbuh, kecepatan tumbuh relatif, T50 dan panjang akar. Data hasil pengamatan dianalisis menggunakan analisis ragam dan dilanjutkan dengan uji DMRTα=0,05. Hasil penelitian konsorsium endo-rhizobakteri mampu meningkatkan viabilitas dan vigor benih padi gogo lokal. Perlakuan konsorsium endo-rhizobakteri isolat Be02 + PKLK5 + Bacillus sp. CKD061 efektif meningkatkan daya berkecambah (25,49%) dan potensi tumbuh maksimum (26,32%) bila dibandingkan dengan kontrol. Perlakuan konsorsium endo-rhizobakteri isolat Be02 + Bacillus sp.

Abandoned mining site is a place that can be used a plantation area or fish cultivation which could greatly benefit the surrounding community. In general, vegetation cannot easily grow in former area of coal deposit for years. Nevertheless, this is not the case with the advanced biotechnology at hand. This research aimed to identify former area of coal deposit that can be used for agriculture and plantation. The investigation went for five months from May 2017 to October 2017 PT coal mining area. BBE Tana Datar, Muara Badak Sub-district, Kutai Kartanegara. The design used in this research was Randomized Block Design in Factorial form where the first factor was biochar and the second factor was mucuna.The first factorswere, B1 (without biochar), control B2 (Biochar 25 kg), B3 (Biochar 50 kg), B4 (Biochar 75 kg), B5 (Biochar 100 kg) in each bed. the second factors were(M1 Mucunaplanted 20 cm x 20 cm and M2 (Mucuna planted 30 cm x 30 cm). The findings conclude that land reclamation at fomer coal mining area with the provision of biochar and mucuna planting is possible even at a low cost and it is also environmental friendly. This enables the area to be utilized for agriculture and plantation.

Rice (Oryza sativa L.) is a food crop as an energy source that is generally consumed by the Indonesian people so that demand continues to increase every year. One of the efforts to increase rice production can be done through the use of young seedlings and microbes to accelerate the process of soil fertilization. This microbe is obtained from the Mas Conch Pest which is processed into Local Microorganisms (MOL). This study aims to determine the effect of giving MOL golden snail and seedling age on the growth and production of rice. This study used a Randomized Block Design (RAK) consisting of 9 treatment combinations and 3 replications. The first factor is the MOL concentration of golden snail, consisting of: 0 ml/L concentration or control, 20 ml/L concentration, and 40 ml/L concentration. The second factor is the age of the seedlings, consisting of: 17 days after sowing), 11 days after sowing and 15 days after sowing. The results showed that the treatment with a concentration of 40 ml/l of Local Microorganisms Conch Mas (M) had a significant effect on the number of productive tillers, the number of pithy grain per panicle and production per hectare. While the age of 7 days after seedling had a significant effect on the number of pithy grain per panicle, weight of 100 grains, and production per hectare. The interaction between the MOL concentration of 20 ml/l golden snail and 7 days after sowing (M1U1) gave a significant effect on the weight of 100 grains.
