| dc.description.abstract | This research was performed to determine the potency of Rianiate’s
geothermal an alternative of energy source and determine the types of geothermal
that was begun with the position’s measurement by using GPS (Global Position
System), and then the direct observation of chemical and physical properties such
as pH, surface’s temperature, color etc. The following steps were taking sample in
four different springs indicated by spring 1, spring 2, spring 3, and spring 4. The
chemical nature was measured by titrimetry method by using AAS, XRD, and gas
Chromathology. The calculating of temperature of subsurface has done by using
geothermometer and sequentially followed by geothermal potency’s calculation.
The position of four springs are located about N: 02o 31,852’ and E: 098o
44.
021’ where were average height from sea’s level is 958 m. The highest surface’s
temperature is 80 oC and the temperature under soil is about 130.5 oC described
the average of geothermal. The calculation of content of chloride, sulfate,
bicarbonations revealed that the water can be categorized as chloride type. The
trilateral diagram Na/1000 – K/100 - Mg of hot water is in the regime of
immature water. From the calculation of Indonesia’s Standardized Geotherm, it
was obtained that the estimated reservoir potency of Rianiate geotherm is 2,68
