Abstract

This study aims to group earthquake damage from its magnitude scale and visualize it on a geographical map. The magnitude of the earthquake was grouped using the K-means model. It is one of the most popular and effective clustering models in grouping data, such as earthquake data. The dataset used in this study is earthquake data for the last ten years on Lombok Island. The optimal number of clusters was used which is 2 in this case, based on the highest Silhouette score of 0.930. The highest Silhouette score shows the optimal number of clusters. The cluster on the geographical map shows most earthquakes' distribution in Northen Lombok Island with cluster 1 consisting of 145 earthquakes, while cluster 2 consists of 3 earthquakes. In addition, the earthquake's damage based on its magnitude scale, there were four different kinds of earthquake damage: slight, limited, minor, and severe damage that have occurred for the last ten years in Lombok Island. Minor and Slight damages were dominant, respectively. However, severe damage occurred in the northern part of Lombok Island due to an earthquake in 2018.

Abstract

This study examines the principles of news content based on multicultural values at TVRI Samarinda Station through a framing analysis approach. As a public broadcasting institution, TVRI Samarinda plays a pivotal role in promoting national identity and cultural diversity while facing challenges related to human resource development and technological adaptation. Drawing on news construction theory and framing theory, this research explores how news content broadcast by TVRI Samarinda constructs and reflects multicultural values within society. The study employs a qualitative research method with a constructivist approach. Data were collected through in-depth interviews with key stakeholders at TVRI Samarinda Station, including the Station Director and the Head of the News Division. The findings reveal that the news scripts broadcast by TVRI Samarinda have successfully addressed multicultural issues, although the newsroom team still requires a deeper understanding of socio-cultural dynamics. TVRI Samarinda has demonstrated its capacity to maintain social harmony in East Kalimantan as a media entity with the mandate to foster national unity. Consequently, TVRI Samarinda plays a significant role in preserving social cohesion and fostering awareness of cultural diversity within the community.  This paper contributes by revealing how TVRI Samarinda constructs and promotes multicultural values through its news framing, thereby strengthening social cohesion and enhancing the role of public broadcasting in a culturally diverse society.
