Corpus-Based Analysis of Online Hoax Discourse on Transportation Subject Picturing Indonesian Issue

Abstract

This research discussed Indonesian hoax on transportation, spread using chain messages over social media, a major hoax subject. Setting social structure as an element to consider in hoax discourse gave different perspectives on why  hoax news took place. Contrasting identified online hoax discourse to corpus-derived prosody could be interpreted using  a sociopragmatic approach by Lin and Chung (2016). This research tried to look at how discourse on hoax correlated to  real social issues among Indonesian people. Digital forensic was done by tracking discourse used as data from hoax news  collection on turnbackhoax.com during 2017-2019. Discourse was later generated into clusters of subject idea of ‘tilang’, ‘jalan tol’, public land transport and infrastructure, ‘kecelakaan pesawat’, ‘lowongan kerja’, ‘China’, insecurity  toward government and ‘kecelakaan kapal’. The subject idea was later consulted to Indonesian Web Corpus (IWAC).  Through the socio-pragmatic approach, prosody derived by contrasting process portrayed hoax on transportation as a  reflection of unsolved current social problems among Indonesian community including distrust toward the government,  unawareness on transport safety, law and regulation, economic status, and trend. The finding of this research is  recommended to take action toward those problems to eliminate hoax spread in the transportation sector.
