In 2004 it was my scientific journey to uncover natural phenomena. I as a guide to extra-curricular activities, the Youth Scientific Group, decided to conduct a study in the Bat Cave in Jabranti Village, Karangkancana District, Kuningan Regency, West Java, Indonesia. The results of our study concluded that the cave was formed from coral. It was estimated that thousands of years ago that this place was the coast which was marked by the number of marine objects found in the area.
