Abstract
ABSTRACT The purpose of this study was to identify post-mining land use practices in Cibeureum Village, Cimalaka District, Sumedang Regency, West Java Province. This area is rich in mining natural resources, especially the C-quarry mine. Even though various regulations regarding mining land exploitation are available, in reality there have been many neglections of these lands after mining. However, it is different from what happened in the village of Cibeureum, the land at the foot of Mount Tampomas, in which there are deposits of sand and rock mining, post-mining can still be used for agricultural activities by the land reclamation method conducted by the local community. This paper will describe how local communities have a concern in utilizing post-mining land through the reclamation method? What factors drive local people to want to use post-mining land? The analysis was carried out through participatory observation methods, focus group discussions, and in-depth interviews with relevant stakeholders. The results showed that the main thing underlying it was the existence of a collective awareness of the community to be able to live as a form of pious charity because of Allah SWT.

Abstract
Styrofoam waste was used as a lost circulation material to prevent sudden and simultaneous drilling fluid losses. In this study variations of styrofoam amount and temperature were carried out to see the effect of mass and temperature on physical and rheological properties of drilling mud. Measurement of mud properties using Viscosimeter (Fann VG Meter) with rotor rotation speed of 300 RPM and 600 RPM. The results of the study were then compared with the drilling mud standard. The values of viscosity, plastic viscosity, yield point, gel strength and mud cake increased when the amount of styrofoam added to the mud increased, after the mud was heated to 243°F there was a decrease in the physical and rheological properties. Water loss value will increase along with the addition of LCM substances into the composition and temperature raised in the range of 0.6 mm -1.7 mm. pH level decrease but with a mixture of pH control substances, the pH of drilling mud maintained in alkaline conditions which ranges from 9.5-11.5. The combination of mud that best fits with the standard was addition with 1 grams of Styrofoam and heated in 243oF.

Abstract
Abstract The Ayung river basin is the largest watershed in the Bali-Penida River Region with an area of 306,149 km2 with a river length of 71,791 km. This watershed through six districts/cities. Population growth and the demands of a more viable livelihood have encouraged people to continue to strive to meet all their needs and the development of tourism in Bali which is growing rapidly, but behind that there will be negative impacts caused mainly on the river water environment and river estuary. Industrial waste and household waste transported in river waters from year to year continue to increase. For this reason, it is necessary to evaluate the environmental conditions of river estuaries and environmental arrangements to be able to support water needs and tourism activities. The aim of this research is to make a model of conservation of water resources at the River Ayung estuary with ecotourism based. The research method uses quantitative and qualitative research methods by involving the researcher in a participatory manner in the subject of the research, ie the users of water and administrators of the traditional village of Kertalangu, Kesiman. For this reason, changes are needed as follows: object changes are subject to research. The research location is the estuary of the Ayung River. Data to be taken are data on changes in land function, climate, population, topography, bathymetry, land use, river boundaries and coastal boundaries, estuary values, orientation of water sources, functions of land around the river estuary. The results of the study of conservation of water resources in the Ayung River Estuary were 15.37 m3/sec, this conservation was carried out by building reservoirs downstream, to meet the water needs of the people in Bali Province designated as raw water, tourism water and 9542 ha of irrigation water.
