Setyani I, Budihardjo MA, Muhammad F.  2020. The determination of soil quality indicators from ex-mining reclamation. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang  20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Soil plays a role in maintaining and improving environmental quality. As a result of mining activities, the soil quality will decline. There are six key indicators to determine the recommended soil quality, namely soil organic matter content, soil acidity, soil bulk density, available water capacity, soil aggregation and respiration. There is also a need for a policy regarding reclamation as a form of controlling ex-mining land. Reclamation is a soil management activity which includes improving the physical condition of the soil, constructing reservoirs to improve the quality of mine water, and revegetation activities. Reclamation activities must be carried out in an effort to reduce environmental damage and divert the function of ex-mining land into agricultural land. This paper aims to explain the determination of soil quality indicators and the factors that support the success of ex-mining land reclamation. With the success of reclamation carried out on ex-mining land, it is hoped that environmental sustainability and agricultural sustainability can be maintained to support food security

Up Flow Anaerobic Sludge Blanket (UASB) In The Paper Industry

The paper industry is an activity that have a large impact on the quality of natural resources. The large amount of water used has an impact on the wastewater generated. Untreated liquid waste can cause pollution in water bodies (rivers). Wastewater treatment with Up flow Anaerobic Sludge Blanket (UASB) is able to process wastes with high COD content in the paper industry. This paper provides a basic review and UASB research that has been carried out in the wastewater treatment of the paper industry
