| dc.description.abstract | ABSTRACT
Existence of underground cave (bunker) in Jembayan has been known for long, but
underground pathway was sealed and lost due to landslide. Goal of this research is to identify
existence of underground cave (bunker) pathway based on magnetic data analysis.
Topographic data acquisition with Theodolit and magnetic data acquisition with Geotron
Model G5 Proton Memory Magnetometer at May 2nd 2019 with 98 observation point and
space between observation point of 5 meters. Data processing carried out with diurnal
variation corection, IGRF correction,. Upward continuation and reduce to pole. Modeling
cared out by analyzing magnetic field anomaly that has been reduced to pole and upward
continuation with 10 m height. Based on the analysis results and pathway cave magnetic data
interpretation in Jembayan area shows existence of continuity from observation bunker and
main bunker to north direction confirmed by higher magnetic field value between 230.1 to
