Abstract

Institute of Technology Sumatra (ITERA), as an educational institution located in the Lampung Province, continues to strive for the development of educational support facilities such as lecture halls and laboratories. The ITERA campus is in an area with potential natural disaster threats like earthquakes, due to the tectonic activity of the Great Sumatran Fault and the subduction of the Indo-Australian plate and the Eurasian plate. To mitigate the risk of disasters on the ITERA campus, infrastructure development planning requires a seismic microzonation study. This research was conducted to determine the dominant frequency (f0​), amplification factor (A0​), and seismic vulnerability index (Kg​) using the Horizontal to Vertical Spectral Ratio (HVSR) method. The results show that the dominant frequency (f0​) values range from 1 to 4 Hz, the amplification factor (A0) from 1.8 to 4, and the seismic vulnerability index (Kg​) from 2 to 15. The seismic microzonation map of the ITERA campus, the northern part of the area is categorized as having a medium to high seismic vulnerability index (Kg​), with a low dominant frequency (f0​) and a high amplification factor (A0​).

Abstract

This article aims to outline the main ideas about social sciences, the scope of their studies, and their relevance in modern life marked by technological developments and globalization. The results of the study show that social science has an important role in helping humans understand various social phenomena, such as social interaction, cultural change, social conflicts, and the development of modern society. In addition, social sciences also function as a means of education that is able to form social awareness, critical thinking skills, and responsibility as citizens. The novelty of this article lies in the discussion that not only outlines the basic concepts and scope of social sciences, but also relates them to societal challenges in the digital era and globalization. Through this approach, this paper provides a more complete view of the important role of social sciences in responding to the increasingly diverse and complex changes in today's life.
