A The Indonesia-Malaysia border as a simulacrum of nationalism: A hyperreality study of the Jagoi Babang community in West Kalimantan

In this article, we investigate how the simulacra perpetrated by Malaysia and the efforts of the border communities of Jagoi Babang to maintain their identity through a spirit of nationalism towards Indonesia. The border region is a complex space that requires a thorough understanding to avoid being affected by the simulacra perpetrated by the neighbouring country. Drawing on Baudrillard's theories of hyperreality and simulacra, this research explores how border communities filter the various simulacra efforts by Malaysia to change the reality of border communities towards Indonesia. A case study approach involving observation, documentation, and interviews with 15 informants from various backgrounds. The research findings show that the Malaysian state performs simulacra by providing easy access to various facilities, such as educational and health services, as well as to economic opportunities, such as shopping and the use of the ringgit in transactions. In addition, this study shows the efforts of border communities to filter simulacra by strengthening nationalism in Indonesia through the use of Indonesian and local languages, as well as through cultural defence, regularly conducting cultural activities and collaborating with related elements. This study provides practical implications for border communities, government and social workers, especially in designing policies to defend the sovereignty and nationalism of the Indonesian nation.
