At the end of 2020, I did a field trip to Kebumen, Central Java. I did geological mapping there, studied the history of the formation of the places I visited, took stratigraphic cross-sectional measurements, analyzed joint and fault structures, made geological trajectories. I did field studies for 1 month with my classmates. Every morning I always go to the field until the afternoon, then at night my friends and I make a report that has been obtained from the field. The field study experience in Karanggulung, Kebumen was very exciting. I became proficient in conducting survey activities and other geological mapping. A very beautiful end of 2020, thank you 2020..
