Taman Ayu Village in Gerung, West Lombok District, has a prospect as an up-coming tourist area. It is unfortunate if the coastal sand mining activities damage the coastal regions. The research conducted aims to describe the level of understanding and attitude of the community towards the impact of mining illegally. This research method is descriptive, with a qualitative approach by using observation, in-depth interviews. The results of the study show that mining is carried out by the community, because of the need for beach sand for building materials, especially as the final content for making ornaments or home decorations. Coastal sand mining caused a decrease in the beach surface, potential disasters, and coastal abrasion. The positive impact of these activities is increasing the income of the mining community. The community has understood that sand mining activities cause damage to coastal areas, but due to economic demands, the community continues to carry out these activities. In tackling illegal mining on the central coast, the role and responsibility of the Government is integral.

Artisanal and small scale gold mining (ASGM) activities usually use the amalgamation process with mercury to extract the gold. The waste of amalgamation is disposed of in a pond or discharged directly into the river. Most of the tailing ponds are located close to the community wells due to water supply purposes for the amalgamation activity. The amalgamation activity could cause mercury pollution to the community well. This study is aimed to determine the mercury concentration in the groundwater in Southern Lombok Coast. The method used during the study were observation and laboratory testing for mercury concentration. An observation activity had been completed at three villages, namely West Sekotong, Pelangan, and Batu Putih, to identify the process of amalgamation and tailings disposal. Ten community wells associated with the amalgamation process were taken as the sample locations for mercury laboratory testing. It was found that the mercury concentration at the nine location samples was below 0.06 µg/l, and only one location sample (sample code P2) was detected with mercury concentration more than 0.06 µg/l. The results indicated that most of the community wells water met with the government standard (Hg = 0.005 mg/L) as stipulated in government regulation No. 82 of 2001.
