The research was conducted using Theo van Leeuwen’s theory on critical discourse analysis. Four online media consisting of KOMPAS.com, detik.com, Liputan6.com, and Tribunnews.com were chosen as data sources for this research. This study uses a qualitative method. Data in the form of phrases, clauses, and sentences were collected through reading and note-taking techniques. Then, the data were analyzed using a qualitative descriptive approach. The research results showed that the online media of KOMPAS.com, detik.com, Liputan6.com, and Tribunnews.com used exclusion and inclusion strategies in producing news discourse. However, KOMPAS.com and detik.com online media tended to use exclusion strategies that included passivation, nominalization, and substitute clauses. Furthermore, Liputan6.com and Tribunnews.com online media tended to use inclusion strategies such as nomination-categorization, nomination-identification, and differentiation-indifference.

These findings suggest readers to read information in the mass media critically. Thus, readers are not easily influenced by the conflicts that are reported
