Abstract

The high value and economic prospects of precious metals, have not been able to cover the environmental, health and social and economic impacts. The conversion of land functions and open pit mining activities as well as the amount of sediment waste causes very significant landscape and environmental changes. This study aims to evaluate the impact of using mercury and cyanide based on the knowledge and experience of actors (miners and gold processors) and the surrounding community on the island of Lombok. Field data collection was carried out by triangulation, namely in-depth interviews with actors and the community, and secondary/reference data from related agencies, especially the health center and several related research results. Gold extraction on the island of Lombok uses two methods which are carried out in stages, namely Amalgamation with mercury in the shelling process and Cyanidation with Potassium Cyanide in the bagging process. The results of the study show that the negative impacts of the mining process are more due to land clearing and miner safety. The impact of gold extraction using mercury is long-term, so it is difficult to identify the impact. Meanwhile, the impact of the use of cyanide is directly felt and seen by the public, especially in terms of decreasing the presence and yield of fish caught in rivers and coasts.

Abstract

Sesaot River is a river located in Narmada, West Lombok. The Sesaot River has been widely used by the surrounding community for their agricultural, plantation and daily activities. The high activity of the people around the river causes a decrease in the quality of river water. Macrozoobenthos is a bioindicator that can be used to describe a water's air quality. The purpose of this research is to examine the water quality of the Sesaot River utilizing macrozoobenthos as a bioindicator. The study was carried out at three different locations along the Sesaot River: upstream, middle, and downstream. At each observation site, macrozoobenthos ecological study and measurements of river water physical and chemical parameters were performed. According to observations, the pH, DO, and TDS of river water remain within the range of acceptable environmental quality standards. The macrozoobenthos found in the Sesaot Narmada river consist of 3 classes, 8 families and 8 species. Gastropoda, Mollusca, and Insecta are the third class discovered. The macrozoobenthic diversity index values discovered ranged from 0.8 to 1.35. Based on these findings, the macrozoobenthos diversity at the three locations is low. The uniformity index values obtained at the three stations ranged from 0.03 to 0.07, indicating that the distribution of individuals was unequal and unbalanced. At the three stations, the dominance index ranged from 0.27 to 0.55. Based on the findings, it is possible to conclude that the water quality of the Sesaot Narmada river is moderately to badly polluted.

Abstract

Leming Village is a village located in the Terara District, East Lombok Regency, which is known for its large number of cattle breeders. The cow manure produced by these livestock has become an important issue that needs to be addressed in Leming Village due to the increasing amount of waste produced. Livestock waste, such as cow manure and other organic materials such as leaves, rice straw, and corn stalks, are the main sources of organic fertilizer. This organic fertilizer is useful in building soil fertility, especially if its use is done continuously over a long period of time. This activity aims to increase the understanding and skills of the community in managing cattle manure and organic waste into compost that is useful for agriculture and environmental cleanliness. This activity is carried out through socialization activities regarding the organic compost program from cattle manure and organic waste, implementation of activities in the form of counseling and compost making techniques from cattle manure and organic waste, as well as additional materials that will be used to accelerate compost making, then conducting evaluation and monitoring as well as community assistance. The results of the compost making process showed that temperature and pH checks were carried out twice, where the checks were carried out in the first and second weeks after the compost was made. The temperature check results in the first week showed that the temperature of the compost was 35°C with a pH of 5.5 and in the second week showed a value of 27°C and pH 7. With this activity, the community can process cattle manure into organic fertilizer, reduce the cost of purchasing chemical fertilizers, and maintain soil fertility better than the use of chemical fertilizers that can reduce fertility.
