The security crisis in West Papua is getting hotter in recent days, although the escalation of the conflict is sometimes high and sometimes low. The shooting of TNI officers assigned there is often the target of gunfire by armed criminal groups in West Papua, as well as innocent local people who are also victims of these incidents. So, it is necessary to hold a mutual peace agreement to reduce losses due to shooting incidents. The crisis communication strategy is considered to be a solution to produce a peace agreement between Kopassus as an institution that represents the Indonesian government and the armed groups or OPM (Free Papua Organization) in West Papua. The crisis communication strategy is considered appropriate to be carried out in the midst of two parties who have different thoughts.

Fires are considered a potential threat to the environmental development because of their effects to the ecosystem and the impact of carbon emission on biodiversity. This study aims to describe news frame republika.co.id and bharian.com.my for forest and land fires in Sumatra and Kalimantan. Using descriptive-qualitative forwarded by Robert Entman's framing analysis model, analyzing the root of the problem, the cause of the problem, moral judgment, and recommendations.

On the issue of the root of the problem, the attitude of both of them blamed forest burners and the role of companies as actors.

This study aims to determine the Problem-Based Learning model based on the REACT approach to students' 21st-century skills. This type of research is meta-analysis research. The data sources in the study came from the analysis of 13 international and national journals that have been published from 2018-2023.  The data source search process is Google Scholar, Hindawi, Eric, ScienceDirect, Springer, and ProQuest. The inclusion criteria in this study are 1) Journals or proceedings indexed by Scopus or SINTA; 2) The type of research is experimental or quasi-experimental research; 3) the dependent variable is the students' 21st-century skills and the independent variable is the problem-based learning model based on REACT; 4) The research has data that can be calculated the effect size value and standard error. Data analysis is quantitative analysis with the help of the JSAP application. The results of this study show that the average effect size value is 1.078 with very high criteria. This finding concludes that the REACT-based problem-based learning model has a significant effect on students' 21st-century skills. The REACT-based problem-based learning model makes students more active and easy to understand learning concepts.
