Analysis of the Characteristics of Geothermal Manifestations in Kalewaha, South East Minahasa District, for Tourism Object Development

Abstract

In North Sulawesi there are nine points location that have considerable geothermal potential but have not developed optimally one of them in Southeast Minahasa that has never been done research. The purpose (Aims or Objective) of this research is to know the nature of manifestation of hot springs using limited physical, chemical, and microbiological parameters and to know the quality of water manifestation for the development of geothermal potential in tourism sector. The research method is (The method of this research use was) direct field research, sampling and analysis in the laboratory. Results of Physical, Chemical, and Microbiological analysis of low-fueled research areas with temperature manifestation of 40 ° C, pH 6.8, Color 5 TCU, 93 mg / L Density, Substances Dissolved (TDS) 1320 mg / L, Sulfate 623 mg / L, Bicarbonate 235 mg / L, Chloride 70,6 mg / L, Nitrite <0,001 mg / L, E. coli 1305 MPN / 100mL, Total Coliform 8650 MPN / 100mL and good quality, Kalewaha Hot Spring can be developed and utilized for Hot water bath activities.
