Developing physics learning devices focusing on natural disaster mitigation in the coastal area of the gulf of Tomini to foster the attainment of SDGS goals 4 and 13

The research is aimed at developing natural disaster mitigation-based learning devices and analyzing the quality of the devices through their validity, practicality, and effectiveness. It was development research referring to the 4-D model design made up of the define, design, develop, and disseminate phases. The results suggested that the developed devices were valid, practical, and effective. The assessment of two expert validators and the data affirmed the validity of the devices. We decided that the devices were practical based on our analysis of the learning process implementedness and observations of student activities. The learning process implementedness was very good at 90.79%. Student activities came with a very good result at 62.5% and a good one at 37.5%. The devices were considered effective predicated on the assessment of the project of the observation report of natural disasters in a coastal area with a very good assessment criterion. Additionally, the consideration was predicated on student learning completeness of 100% at an N-gain of 0.69, considered medium. In conclusion, our physics learning devices focusing on natural disaster mitigation in the coastal area of the Gulf of Tomini to impel the realization of SDGs Goals 4 and 13 were valid, practical, and effective.
