Geologi dan Potensi Batubara di Daerah Bonggo dan Sekitarnya Kabupaten Jayapura, Propinsi Papua

Abstract

Geographically, the study area is in the region and surrounding Bonggo, Jayapura Regency. Now a
days, the energy needs requires a continuous exploration in energy commodities (oil and coal).
Geologically, Jayapura Residence has considerable potential for coal commodity. The research itself
is located at coordinates 139025'51 "- 139039'37" BT and 2038'20 "- 2027'46" LS. The method used in
this research are geological mapping, SRTM image interpretation and analysis of the gravity anomaly.
From the results of research have encountered the presence of local coal on the river wiruway but has
untapped potential to be mined economically. From the analysis of satellite imagery and SRTM data
processing gravity so, alleged anomalies while the potential presence of a carrier lithology of coal is
relatively in eastern and widespread to the north as indicated by the value anomaly contour growing
eastward. This is supported by existing of coal deposits in the east outside the study area.
