Abstract

Rancaekek Area, West Java, known as rice granary for years. But, since thetextile industry growing, rice productions are continued to decrease. It waspredicted as the impact of pollutant migration into the farmland. Nowadays,farmland in this area was tend to gone. The potential spread of pollutants can be observed through the direction of groundwater movement. Mass movement ofground water can be seen through the groundwater flow model. This study willprovide an overview of potential spread of pollutants, because it will follow thegroundwater flow. The model is built through data processed with GeographicInformation Systems (GIS). The simulation results of groundwater level isgenerally known that pollutants will move to the south, with local variations tosoutheast and southwest.

Abstract

This study aimed to determine the capability of top soil fertility which will becuted from mining area and will be used as main material in land reclamation.This research conducted in term that there will be mining activity in TanjungBaru, Bakong Village, Singkep Barat District, Lingga Regency of Riau Province,with total area 106.62 ha. The mining activity will cut the top soil 5,608,643 m3or equal to 6,730,372 ton of soil. The cutted soil will used to be main material ofland reclamation and become a substrat for revegetation plants. The resultshowed that the capacity of study field soil fertility was categorized as very low tolow. In order to preserve the soil condition, it must be properly stored. Therecommendation from this research is, it needs to re-analysis of soil conditionbefore used to revegetation in order to test the land fertility status, and as thebasic for determine the fertilizer dose that can be applied.
