On Thursday, July 21, 2022. Three lecturers of the Geophysics study program namely Refrizon, S.Si., M.Si (Chair), Dr. Arif Ismul Hadi, S.Si., M.Si, and Nanang Sugianto, S.Si., M.Sc who were assisted by three Geophysics students namely Andre Rahmat Al-Ansory, Eko Purwanto, and Hana Raihana conducted a socialization of abrasion disaster mitigation to village officials of Urai Village, Ketahun District, North Bengkulu Regency, Bengkulu Province. This activity was carried out in the framework of community service program activities by lecturers of the Physics study program funded by FMIP Bengkulu University. This socialization was attended by 13 village officials, ranging from the Village head to other field officials. The material presented was related to how disaster conditions, especially abrasion that occurs around Urai Village.

Based on studies conducted by researchers, it is agreed that the coastline of North Bengkulu Regency is almost entirely damaged by abrasion. One of the causes is the condition of the rock along the coast to a depth of 30 m which is relatively soft. Refrizon et al, 2019 reported that based on the value of subsurface shear wave velocity at a depth of 0 to 30 m, the stratigraphic constituent rock structure consists of soft soil to soft rock, so it is classified as weak. This weak subsurface rock structure is the main factor causing the high rate of abrasion. When compared to the Southern Bengkulu Province area as reported by Arvolis et al, 2020 rock stratigraphy is classified as hard soil to soft rock. Therefore, land use in coastal North Bengkulu is very important to immediately plan for appropriate utilization and consider building abrasion retaining structures (sea walls).

Urai Village is one of the villages that is severely affected by coastal abrasion. Activities to provide information and community knowledge about the magnitude of the abrasion movement rate have been carried out. Urai Village community representatives such as youth, housewives, village intellectuals, traditional leaders, religious leaders, and businessmen participated in this event. Community perceptions before the socialization were assessed through a questionnaire, and after the delivery of the material were assessed again. Based on the analysis of the questionnaire data, it can be seen that the community is actually very aware of the dangers and impacts of abrasion on their land and lives. The community also strongly supports all productive activities to mitigate this disaster. In addition, the community is also ready to support all efforts from the government and is even ready to move to an appropriate and safer location. All layers including the village government are ready to do the best study results implemented in Urai Village to reduce the impact of abrasion in the future.
