“…Selain itu, perlakuan penyiraman setiap harinya pada K1 mampu mencuci unsur hara, terutama pencucian kation basa pada tanah sehingga pH tanah akan menurun menuju masam. Hal ini sesuai dengan pendapat Tampubolon et al (2020) bahwa kation basa terlarut seperti K + , Ca 2+ , Mg 2+ memiliki kontribusi pada peningkatan pH tanah. Ketika terjadi pencucian, kation basa tersebut dapat digantikan oleh kation asam (H + ).…”

Drought stress and acid soil pH are a form of abiotic stress on acid-dry land. Actinomycetes are a group of transitional microbes that have benefits as bioprotectants, biostimulators, and biofertilizers. This study aimed to determine the optimum growth environment for Actinomycetes at various incubation temperatures (25, 30, 35, and 40 ℃) and media pH (5, 6, 7, 8, and 9) and prove its effectiveness on mustard plants when given drought stress, and increase in acid soil pH. The research was conducted in the LOB greenhouse of PT Great Giant Pineapple using two factors, namely Actinomycetes (F22, F26, F34, F39, and F47) and irrigation (watered and not watered). Observations included Actinomycetes population (CFU mL-1), plant response (percentage of stress, death, survival, recovery), plant growth (plant length, number of leaves, root length), plant production (fresh weight), soil pH, and soil organic matter. Results of this study showed that Actinomycetes F22 gave the highest total population (107 CFU mL-1), and the P4K1, P4K2, and P2K2 treatment combination gave the best results on the observed parameters.

“…Tanah buangan (mine spoil) pada tahap reklamasi lahan pasca tambang memiliki struktur tanah yang belum stabil karena ekosistem belum pulih sepenuhnya. Supaya dapat dimanfaatkan dalam pengembangan ternak, diperlukan pengelolaan yang mempertimbangkan dalam hal terjadinya erosi dan kompaksi tanah (Tampubolon et al, 2020). Oleh karena itu, peternakan di lahan pasca tambang penyediaan pakan hijauan menggunakan teknik cut and carry atau dipotong selanjutnya diangkut ke kandang.…”

“…Kandungan nutrien yang rendah pada rumput odot yang berfungsi sebagai cover crop, terjadi karena tanah di lahan pasca tambang memiliki kualitas yang buruk yang dicirikan dengan gersang, padat dan rentan erosi akibat dari penambangan batu bara secara terbuka. Tampubolon et al, (2020) menjelaskan lebih lanjut bahwa penambangan dengan cara terbuka menyebabkan penurunan kualitas biologi tanah, kimia, dan fisik akibat perubahan pucuk tanah yang bercampur ketika penimbunan penutup tanah (overburden). Tanah bekas tambang memiliki pH, C-organik, dan Ntotal tanah yang rendah (Tala'ohu dan Erfandi, 2013).…”

ABSTRAK. Sapi bali merupakan ternak yang didomestikasi dari banteng liar (Bos banteng) dan keanekaragaman hayati lokal yang memiliki peluang besar untuk dikembangkan. Pennisetum purpureum cv. Mott salah satu pakan hijauan yang berpotensi untuk menunjang kinerja produksi sapi Bali, karena mempunyai nilai nutrien yang cukup tinggi dan palatabel untuk ternak sapi bali. Penelitian dilakukan untuk mengetahui kinerja produksi sapi bali jantan dengan pemberian odot (Pennisetum purpureum cv. Mott) di lahan bekas tambang batu bara PT. Bramasta Sakti. Evaluasi dilakukan pada sepuluh ekor sapi bali jantan dengan kisaran umur 2-3 tahun (poel 2 pasang) selama 2 bulan. Parameter pengamatan penelitian ini meliputi: konsumsi bahan kering (BK), pertambahan bobot badan harian (PBBH), konversi pakan, efisiensi pakan, kecernaan bahan kering (KcBK), kecernaan bahan organik (KcBO) dan feed cost per gain. Analisis data dengan metode deskriptif. Hasil dari penelitian, diperoleh konsumsi bahan kering dengan rata-rata 8,44 kg/hari, PBBH 0,56 kg/hari, KcBK 79,51%, KcBO 71,74% dan efisiensi pakan 6,63%, konversi pakan 15,07 dan nilai feed cost per gain Rp 29.384. Kesimpulan penelitian ini adalah sapi bali jantan yang diberikan rumput odot di lahan peternakan pasca tambang batu bara PT Bramasta Sakti tidak mengganggu kinerja produksi.Kata kunci: Sapi bali, Performa produksi, Pennisetum purpureum cv. Mott, Tambang batu bara.Production Performance of Bali Cattle on the post coal-mining land fed Odot Grass (Pennisetum purpureum cv. Mott)ABSTRACT. Bali cattle are domesticated from wild banteng (Bos banteng) and its local biodiversity that has a great opportunity to be developed. Pennisetum purpureum cv. Mott is a forage that has the potential to support the production performance of bali cattle, because it has high nutritional value and good palatability for bali cattle. The current study was conducted to determine the performance of bali cattle production by giving odot grass (Pennisetum purpureum cv. Mott) in the post coal- mining land of the PT. Bramasta Sakti. Evaluation were made on 10 male bali cattle aged 2-3 years (2 pairs of permanent teeth). Evaluation parameters in this study include: dry matter (DM) consumption, average daily gain (ADG), feed efficiency, feed conversion, feed cost per gain, DM digestibility, and organic matter digestibility. Analyzed data using descriptive method. The results of the study, obtained dry matter intake an average of 8.44 kg/day, the ADG 0.56 kg/day, DM digestibility 79.51%, organic matter digestibility 71.74% and feed efficiency with an average of 6.63%, feed conversion 15.07 and feed cost per gain value IDR 29,384. The conclusion of this study is that male bali cattle fed Pennisetum purpureum cv. Mott in post-coal mining plantations of PT Bramasta Sakti does not interfere with production performance.

Purpose: The purpose of this study is to review the effectiveness of sand mining policies that are controlled and monitored under local government management Theoretical Framework: In managing sand mining, putting attention to environmental ethics is a must so the impact of the sand mining process can be controlled. By understanding sustainable development concepts, government policies regarding sand mining should be more emphasize the human life aspects. Method: This study used a qualitative approach by conducting in-depth interviews with the community around the mining area in Lumajang Regency. Therefore, the impacts of socio-economics can be determined from the explanations obtained. Results and Conclusion: This study found that many dynamics happened because of inconsistent regulations. Lumajang Regency is affected area by these problems as there are many mining sites in Lumajang Regency. Before making environmental management policies, the government need to have a good analysis so the ecosystem can be protected and illegal sand mining activities can be eliminated. Research Implications: This research may use for government considerations to solve environmental problems caused by sand mining activities in Lumajang Regency, Indonesia. Originality/value: This research discusses the problem regarding environmental issues caused by sand mining activity and the solution solved by the government by redesigning the policy to improve the sand mining management quality in Indonesia.
