Abstract

Abstract The salt deposits are unevenly distributed in the world. The most productive countries are China, USA and India. Indonesia experiences the salt deficit, due to the limited number of the deposits. The evaluation of the characteristics of salt deposit in the world reveals the Pre Tertiary association in semi closed marine environmental deposition. The geological condition in Indonesia does not favor such environment, therefore the salt deposits unlikely to occur. The saline solution in mud volcanoes in northern part of Java Island however indicates the possible saline deposits in Tertiary Kalibeng Formation with the thickness of approximatelly 3.000 meters. The saline seepages most probably have continuously been taking place since early Pleistocene or about a million years ago. The saline seepages in northern part of East Java might extend to thebottom of Madura Strait and enrich the salinity of the sea in the strait. The semi closed configuration of the strait contributes to the accumulation of salt. It is therefore suggested to expand the evaporating pools for salt production, among others by the reclamation of the shallow offshore area in the southern part of the island. Keywords: salt deficit, mud volcano, saline solution, enrich the salinity, solar evaporating pools

Abstract

Recently, the sustainable management of post-mining land use has received great attention. The mining-closure, due to the mine has no longer economic value, or the mined material has run out; often leaving poor landscapes and degraded land.  The mining company have to rehabilitate the ex-mining land so that it can be returned to its original baseline stage or can be used for other more useful activities. The objective of research is to arrange the sustainable management plan of post-mining land use at ex sand-mining in Indramayu Regency, West Java. The Analytical Hierarchy Process (AHP) approach used to determine the priority of activities that will be carried out on the land. Several criteria and alternative were calculated by Saaty’s AHP pairwise comparison scale.  The research results reveal that in post mining land use management based on sustainable management, economic criteria must be considered first, followed by environmental, socio-culture and finally technical criteria. Fishery, cattle breeding and agriculture were found to be the optimal alternative for sand post‐mining land use.
