Analysis of economic valuation of environmental damage due to sand mine in Gumulung Tonggoh, Cirebon District, West Java Province, Indonesia

Abstract

The sand mines at Gumulong Tonggoh in Cirebon Regency use an open mining system. Open mining activities can cause environmental damage and economic losses. The present investigation was carried out to analyze the economic valuation of environmental damage due to sand mine in Gumulung Tonggoh, Cirebon District, West Java Province, Indonesia. The sampling method and environmental damage analysis use purposive sampling. Data of laboratory tests of soil physical, chemical and biological properties was analyzed by statistical tests. The economic method of environmental damage valuation uses the Ministry of Environment guidelines (2006). Sand mining activities cause soil and environmental damage to the soil (soil solum, bulk density, permeability, and soil fauna) and vegetation (land cover). However, sand mining has caused changes in soil properties, namely a significant increase in bulk density of +0.49 (53.85%), reduction in porosity of 18.26 (27.79%), decrease in Ca of -11.17 (60.48%), a decrease in Mg of -5.76 (60.95%), a decrease in CEC of -19.06 (79.88%) and a decrease in the total microorganism of 47.00 (83.19). The total of economic valuation for environmental damage due to sand mining is Rp. 39,349,860,000. Therefore, the sand mining significantly contributed the environmental damage in the Gumulung Tonggoh, Cirebon District, West Java Province in Indonesia.
