Abstract

Apart from ex-mining land which requires management and rehabilitation using soil microbial communities, reclamation activities require time and technology with high costs and results that are not necessarily effective and efficient. One effective way is to provide organic fertilizer which contains lots of microbes and is able to neutralize soil acidity. This type of research is experimental research with a research design using a Completely Randomized Design (CRD) 4 x 6. The population of this research is all Ruji Nut Plants (Pueraria Javanica) that grow in the PT Mine Wire House area. The main natural coal sampled in this research were 24 Ruji Nut Plants (Pueraria Javanica). The results of this research were that administering NPK solution and Micro Nano Bubbles (MNBs) was proven to help accelerate stem growth, number of leaves, number of leaf branches, root length and increase the biomass of Ruji Nut (Pueraria Javanica) plants in planting media with minimal topsoil. The dosage of Organic NPK Solution and Micro Nano Bubbles (MNBs) for optimal growth of Pueraria javanica plants was in treatment 4 (90 ml), where in treatment 4 the average stem growth, number of leaves, number of leaf branches, root length and plant biomass reached optimal point. So the use of Organic NPK solution using Micro Nano-Bubbles (MNBs) is more effective and environmentally friendly because it is formed from organic materials.

Abstract

This research was conducted at one of the coal mines in Tebo Regency, namely PT. Asia Multi Investama. The technique for determining respondents was determined by purposive sampling with a sample size of 54 people. The data analysis techniques used are laboratory analysis (water and land), descriptive analysis (to determine the reclamation model) and sustainability index measurement using multidimensional scaling (MDS) from the three dimensions of sustainability analyzed, namely the social dimension and the economic dimension. and ecological dimensions. The results of soil and water laboratory analysis show a decline in soil and water quality. The results of observations of vegetation in the field also showed a decrease in plant growth. Management of post-mining reclamation land PT. The current Asia Muti Investama is quite sustainable with an Appraisal Post Coal Mining Sustainable (APCMS) score of 55.27 on a scale of 0 -100. The reclamation model that can be applied is the agroforestry reclamation model with the agrosilvofishery system. The leading tree commodities are rubber and palm oil. For fisheries, this is a place for fish breeding in former mining ponds (voids) with types of tilapia, goldfish and catfish. Sensitive factors as levers that influence the sustainability of PT's former coal mining land. Asia Multi Investama.

Abstract

The purpose of this research is to analyse the potential of water catchment areas and the impact of land cover change from 2010 to 2024. The research method used is quantitative research, with a descriptive approach. The analysis technique in this study uses the maximum likelihood analysis method, in analysing the classification of land cover in 2010 and 2024, and overlay analysis in analysing the potential of natural water catchment areas, land cover changes in 2010-2024, and the index of potential water catchment areas. Based on the results of the study, it can be concluded that the Batang Arau watershed has experienced a decrease in the area of potential water catchment areas, covering an area of 1057.80 hectares with a percentage of 5.94%, although it has increased the potential of water catchment areas covering an area of 238 hectares with a percentage of 1.34%, but the increase is not proportional to the decrease that has occurred. This decrease is due to land cover change from 2010-2024, with a reduction in forest area of 5.93%, wetland agriculture 2.49%, water bodies 0.02%, and grass 0.53%. This was accompanied by an increase in built-up areas of 7.94%, mixed gardens 0.73%, fields 0.10%, natural open land 0.002%, and shrubs 0.11%, So it can be concluded that the decrease in water catchment area is due to the reduction of forest area (natural vegetation), accompanied by an increase in built-up area
