Merapi Volcano National Park (MVNP) is susceptible to volcanic hazard since it is located around Merapivolcano, especially pyroclastic flow. Carbon sequestration in the national park is becoming a priority of forest developmentas stipulated in Government Regulation Number 28 Year 2011 and Number 49 Year 2011. This study aims to knowthe effect of pyroclastic event to carbon stock in MVNP. In this study the natural carbon rate recovery in MVNP wasestimated to determine the growth rate of natural carbon recovery in MVNP. To estimate carbon stock change in MVNP,2006 QuickBird and 2011 GeoEye satellite imageries were used. Object based image segmentation of high resolutionsatellites imagery could recognize physical dimensions of individual trees such as crown projection area (CPA). In thisstudy, carbon stock was derived using allometric equation based on measured diameter at breast height (DBH) in thefield. A model was developed to estimate carbon stock based on DBH estimation in the field and segmented CPA fromthe image. Based on the segmentation process, the model of CPA and Carbon in MVNP was developed. The F scorewhich indicate the accuracy of segmentation of needle leaf and broadleaved of 2011 GeoEye were 0.68 and 0.54 respectively.Logarithmic model which has 6.37 % error was used to estimate broadleaved carbon stock while quadratic modelwhich has 10.31 % error was used to estimate Pine tree carbon stock in MVNP.
