Mount Merapi and Mount Merbabu are active volcanoes that lies in Java Island. Java island is part of Indonesia region. This island was subduction product of Eurasian and Indo-Australian plates, caused the island consist of many volcanoes. A regional gravity study was carried out over Mt. Merapi-Merbabu by TOPEX/Poseidon satellite data. The data was corrected by free air correction and become free air anomaly. Then, that anomaly was corrected by Bouguer and Terrain corrections, become Complete-Bouguer Anomaly. This study present subsurface density model beneath Mt. Merapi and Merbabu to identify the magma chamber.
