The focus of monitoring was the plant purposely cultivated because after re-vegetation, there were a very few of other plants growing naturally on reclimed coal mining area which were recorded, whereas these plants had important values. The research aimed to record all plants and to identify predominant plants over the reclaimed land of PT 2 Adaro Indonesia. There were four sampling locations with 13 squares of 50 × 20 m on each location established and 2 on each square there were 5 plots of 2 × 2 m plotse made. Both plant species and its individual number of woodyplant saplings were recorded on each square, so in each plot, there were small species and its individual number of either woody-plant seedlings or non-woody plants (herbs/shrubs, grasses, ferns). The relative density and the relative frequency of woody or non-woody plants were summed to obtain the important value index (IVI) of each successional stage. There were 107 plant species consisting of 32, 43, 27, and 5 species of saplings, seedlings/herbs/shrubs, grasses, and ferns respectively. From those species, 16 species of woody plants and 2 species of herbs were planted purposely,other species grew naturally and even some of them were dominants. Either the number of plants or the dominating plant is varied according to the sampling location and the growing stage.

Soendjoto MA, Riefani MK, Triwibowo D, Metasari D. 2018. Birds observed during the monitoring period of 2013-2017 in the revegetation area of ex-coal mining sites in South Kalimantan, Indonesia. Biodiversitas 19: 323-329. The number of bird species in the reclaimed and revegetated ex-mine site increases as the vegetation age increases. To test the hypotheses, the number of bird species was recorded at 08.00-12.00 and 14.00-17.00, 6-8 days for eight consecutive semiannual monitorings of 2013-2017 in four revegetation sites. Since the second half of 2015, another revegetation site, namely BP was added. Bird species were recorded in 25 m right side and 25 m left side of the observation path and within a radius of 25 m of observation points. To show an increase in the number of bird species, the number of newly discovered bird species in the given semiannual monitoring was added to the number of bird species in the previous semiannual monitoring. The number of bird species in the early semiannual monitoring was used as the baseline value. A bird species was categorized as a resident if the species was observed in each monitoring in the four vegetated sites. Up to the last monitoring, 53 bird species were recorded in the first four sites and 70 bird species in five sites (four reclamation and revegetation sites and one additional site, BP), while in the early semiannual monitoring (second half of 2013) birds recorded were only 30 species. This result shows that the older the vegetation age in the vegetated site, the greater the number of bird species utilizing the site. Seventeen species of birds were categorized as residents. These resident bird species includes White-breasted Woodswallow, Pied Triller, Scalybreasted Munia, Asian House-martin, Pacific Swallow, Long-tailed Shrike, Blue-throated Bee-eater, Olive-backed Sunbird, Sootyheaded Bulbul, Yellow-vented Bulbul, White-breasted Waterhen, Ashy Tailorbird, Yellow-bellied Prinia.

PT Adaro Indonesia merupakan perusahaan tambang batubara yang berlokasi di Kabupaten Tabalong dan Balangan, Kalimantan Selatan. Salah satu kewajiban perusahaan terhadap masyarakat adalah melakukan Pengembangan dan Pemberdayaan Masyarakat (PPM). Program PPM disinergikan dengan program pascatambang agar memberikan manfaat bagi lingkungan hidup dan sosial ekonomi masyarakat sekitar tambang secara berkelanjutan. Sinergi ini dilaksanakan pada demplot pascatambang terpadu Paringin karena adanya kesesuaian potensi biogeofisik area demplot dengan kondisi sosial ekonomi masyarakat sekitarnya. Madu kelulut mempunyai potensi yang dapat dikembangkan di masyarakat, namun selama ini belum dibudidayakan secara intensif. Tujuan kegiatan adalah meningkatkan produksi dan kualitas madu kelulut pada Usaha Kecil Menengah (UKM) mitra di Paringin. Pengembangan budidaya lebah madu kelulut dimulai di area demplot pascatambang kemudian diduplikasi di masyarakat sekitar tambang yaitu Istana Kelulut melalui program Corporate Social Responsibility (CSR) sejak tahun 2018. Kegiatan yang dilakukan pada UKM mitra yang dipimpin Bapak Maskuni meliputi pelatihan budidaya lebah madu kelulut secara intensif, pendampingan dalam kegiatan peningkatan produksi dan kualitas produk madu kelulut, serta monitoring dan evaluasi kegiatan. Hasil kegiatan pada UKM mitra Istana Kelulut menunjukkan adanya penambahan sarang lebah madu kelulut menjadi kurang lebih 300 (tiga ratus) unit (Trigona Thorasica dan Trigona Itama) dengan produksi rata-rata mencapai 30 liter/bulan. Hasil analisis laboratorium madu kelulut untuk jenis Itama pada semua parameter madu memenuhi persyaratan kualitas madu Trigona sesuai SNI 8664:2018. Adapun untuk jenis Thorasica, hasil parameter gula pereduksi sebesar 54,24% yang lebih rendah dari baku mutu 55% sedangkan keasaman sebesar 237,81 mL NaOH/kg yang lebih tinggi dibandingkan baku mutu maksimal 200 ml NaOH/kg.

Coal mining by the open-pit mining method creates the formation of a pit lake. The ex-mining site, over time, was gradually filled with contaminated water and must be returned to the water quality standard of compliance level. With proper treatment, the pit lakes have the potential for several benefits and subsequent uses. This study aimed to analyze the existing condition of the Paringin Pit Lake at South Kalimantan by identifying the quality of the water flow, and it is compliance with the parameter threshold values. The results showed that the pit lake water management had been carried out supported by good management of the catchment area and was indicated the stable category by geology technical study. The success of its revegetation processed in the area was shown by an erosion study in which the result was a very low-level category. No less important is the management of runoff water both in the quantity of water balance control and consistent water quality treatment to meet the quality standard values that have been set. The Paringin Pit Lake water management strategy is a form of activity that demonstrates compliance with good and responsible mining principles to support sustainable development that can serve as a good reference and example for other mining activities in terms of mine closure preparation.
