Development of the Learning Instruction Based on Problem Based Learning Models Oriented with Mitigation of Mount Eruption and Lava Floods on the Mathematical Reasoning Ability of Class VIII Students of SMP / MTs

Abstract

Abstract During 2019, the National Disaster Management Agency (BNPB) noted that there had been 3622 disasters in Indonesia, one of which was natural disasters such as volcanic eruptions and cold lava floods. In terms of volcanoes, Indonesia is the most active volcanoes location in the world and it have many tectonic plates that have the potential to cause volcanic eruptions, tsunamis, and earthquakes. Therefore, the Indonesia Government recommends providing education on natural disaster mitigation in schools. The goal of this study was to determine the mathematical reasoning abilities of students and the knowledge and attitudes of students towards mitigating natural disasters. This research is a development research, the development model used in this research is the Plomp model which consists of three phases, namely preliminary research, prototyping phase, and assessment phase. The instruments used during the research were observation sheets, interview guides, questionnaires, validation sheets for learning devices, and tests of students' mathematical reasoning abilities. From this research, it is proven that about 71.4% of MTsN 6 Agam students stated that there has been no learning about natural disaster mitigation. Based on the results of the mathematical reasoning ability test, there was an increase to 72.7% from the initial test result of 25.47%. Natural disaster mitigation knowledge does not have to be provided to students in specific subjects, but can be integrated into existing subjects, one of which is mathematics.
