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.

Secondary data obtained from the Safety, Health and Environment Department of PT. Winner Prima Sekata (PT. WPS) in Kemingking Dalam Village, Taman Rajo District, Muaro Jambi Regency, in 2022 it was discovered that there were cases of Acute respiratory infections (ARI). Therefore, a study was carried out regarding the analysis of air quality and water quality at the coal port location in Muaro Jambi Regency to determine the extent of the environmental impacts resulting from coal loading and unloading and stockpile activities at the Talang Duku port, Jambi Province. The research was conducted using quantitative survey and descriptive methods. Data analysis is quantitative in nature with the aim of testing predetermined hypotheses. Dust measurement results obtained between 7.98 - 10.00 mg/m3, The allowable dust threshold value is in accordance with the Minister of Manpower Circular Number. SE.01/MEN/1997 concerning the NAB of Chemicals in Workplace Air is 0.9 mg/m. So the dust level in the Muaro Jambi coal port working area exceeds the quality standards set by the Minister of Manpower. Results of calculating the output water pollution index pH and TSS at the PT Outlet point. The WPS of port locations in the period March – June 2023 in each month has a Pij value of 1.08, which means the average pH and TSS value of output water from PT. WPS is at status 1.0 < 1.09 < 5.0 with the description Lightly Polluted. Based on processing with SPSS version 27 using the One way Anova test, it was found that Fcount then H0 was rejected.
