Given all the geothermal potential elsewhere in Java, why bother?
It will never exist at much above 100C unless it is kept at extreme pressure, a look at steam tables suggests around 100 bar should do the job which would suggest that (without knowing the SG of the stuff) a tapping at about 1000 meters.
