This website provides you with definitive list of mountains in Indonesia and East Timor.

Indonesia is a nation of volcanoes. The earth' crust below Indian Ocean, moving northeastward........, this great zone of subdiction has produced a mighty chain of volcanoes running 3000km along the length of Sumatra, Java, Lesser Sunda Island. More volcanoes mark the Banda arc, and the tectonically complex region Halmahera, Sulawesi and Sangihe, running toward the Philippines. (Tom Simkin & Richard.S Fiske.,Krakatau 1883, 1987 p20)

There are more then 800 mountains in Indonesia and East Timor. Some of them are active; others inactive or dormant.
