The Change of Carbon Stocks and CO2 Emission as the Result of Land Cover Change for Tin Mining and Settlement in Belitung Island Indonesia

Abstract

Dedi Hermon1 Abstract The research was aimed at formulating the model of land cover mode to determine the change of carbon stocks and CO2emission. Furthermore, this research was conducted to analyze the change of forestry land cover due to tin mining activity and settlement as well as the qonsequences toward carbon stock and CO2emission of Belitung Island, Bangka-Belitung Province, Indonesia. Method used in analyzing the land cover refers to Geography Information System (GIS) analysis previously applied by Zain (2002) and modified and developed by Hermon (2010a); Hermon (2012a); Hermon, (2014a), Hermon (2015); and Hermon (2016). The instrumentation of the analysis of the change of the land cover is GIS-ERDAS 9.1 dan GIS-ENVI 5.1. While the instrumentation used to analyze the carbon stock in each land coved is stratified purposive composite sampling referring to plot technique developed by Hairiah and Rahayu(2007); Hermon (2012b); Hermon (2015).Tree biomass is analyzed through allometric equation developed by Kattering (2001), while calculation of the carbon stock and CO2 emission is determined through a formula developed by Hairiahand Rahayu (2007). The result of the study shows that the width of forestry land cover is decreased and the land cover of active tin mining, farming, and settlement is increased in Belitung Island. The condition directly influences the volume of carbon stock in Belitung Island that the volume of CO2 emission in 1995- 2005 was 800.193.032, 6 ton. The emission of CO2 released is 663.658.471, 8 ton. This is the result of the change of forestry land cover to tin mining areas active and tin mined land as well as human settlement land cover.
