Abstract: Temperature measurements have been done in the prospect area of geothermal Suli, District Central Maluku, to determine the temperature distribution on subsurface. Temperature measurement in monitoring and mapping is done on an area of 400 m x 200 m with two different locations, Suli 1.1 and Suli 1.2. Retrieval data of temperature measurement using a temperature sticks and electronic thermometer incorporating a thermistor as a sensor such as IC LM35. The working principle of this instrument is that the physical phenomena detected temperature sensor is converted into electrical signals in the potential difference, then converted in degrees Celsius. The results of measurements of temperature monitoring at the Suli obtained average surface temperatures between 31.08 oC - 31.13 oC. Distribution of heat on subsurfaces is calculated by solving the heat conduction equation (Laplace) with a finite difference method that has been constructed (known as the Liebmann method). The modeling assumes that two-dimensional objects shaped the plate. The results of modeling heat source on subsurface with finite difference methods estimate the temperature reservoir in Suli is 300 oC at a depth of 1100 m.
