APPLICATION OF THE E-LEARNING MODEL IN EARTHQUAKE LEARNING TO IMPROVE STUDENTS' UNDERSTANDING OF EARTHQUAKE DISASTER PREPAREDNESS

This study aims to describe the application of e-learning in improving students' understanding of earthquake disaster preparedness. This study used a quasi-experimental design with an equivalent time series type. The research sample was taken of grade 10 Senior High School 5 Banda Aceh with a non-probability sampling method. The stage of this research is that students are given a pre-test to see their initial level of understanding before being given a treatment, then students are given a treatment in the form of earthquake preparedness learning through the e learning model. the understanding of students after participating in learning with the e learning model has increased by 14.44 %. As for the n-gain value is 0.54 (moderate criteria), the N-gain value indicates that learning with the e-learning model is effective in improving students' understanding of earthquake disaster preparedness. based on research data analysis it was seen that students' understanding of earthquake disaster preparedness had increased compared to before. Meanwhile, related to the effectiveness of learning, based on data analysis, it was found that learning earthquake disaster preparedness using the e-learning model was effective in increasing students' understanding of earthquake disaster preparedness.


A. INTRODUCTION
Indonesia is a country that is located on three junction lines of active tectonic plates, this is why Indonesia is a country that frequently occurs in earthquakes.Earthquakes are vibrations on the earth's surface as a accompanying symptom of tectonic and volcanic activity and sometimes the collapse of parts of the earth locally.what you feel when an earthquake occurs is the vibration in the earth where we are at that time.The earth shakes sideways and upward (Katsumata et al., 2021).In Indonesia, especially the Aceh province, there was a large earthquake with a magnitude of 9. Educational activities are then held in temporary schools.In many catastrophic events, this condition lasts a long time.
This situation is clearly less favorable for children who have to study with limited facilities, which in the end the teaching and learning process cannot take place optimally (Rababa, 2021).Thus e-learning as an electronic medium can have a changing impact on the learning process.Furthermore, the purpose of using e-learning in the learning system is to expand access to education to the wider community.
From this explanation, it can be concluded that the interaction between students and teachers does not always have to be face to face, students can start learning on their own using electronic media with developing technology as an intermediary so that the teaching and learning atmosphere becomes more interesting and interactive.

B. MATERIALS AND METHODS
This study uses a quantitative approach.This type of research is experimental research with a preexperimental design approach.In this design, the subjects will be given a pretest before treatment (Nismalasari et al., 2016) The three plates are the Eurasian plate, the Indo-Australian plate and the Pacific plate.The movement of the three plates causes the islands in Indonesia to experience frequent vibrations, especially in the area where the plates meet, namely the confluence of the Eurasian plate and the Indo-Australian plate along the islands of Sumatra, Java, and the Nusa Tenggara Islands; and the confluence of the Indo-Australian and Pacific plates around the island of Papua.
3, which was centered at ± 160 KM from the West Coast of Aceh Province.This disaster has generated a massive wave, namely the tsunami wave.The tsunami waves not only swept the Aceh Province but also the coasts of the countries around the Indian Ocean.The lack of knowledge about disasters that is owned by the community makes the community unprepared for the disaster, thus causing many people to die.In addition to the large number of people who died, the impact of the disaster was also very pronounced in the education sector where students experienced difficulties in carrying out learning activities due to damaged educational facilities.Disasters also often have lasting consequences for children.The destruction of educational infrastructure due to the disaster caused children to lose the opportunity to participate in educational activities.
is a network, which makes it possible to update, store / retrieve, distribute and share instructions or information sent to users directly via a computer using internet technology(Milićević et al., 2021).Furthermore,(Foo et al., 2021) defines e-learning as the use of information technology and computers to create learning experiences.Based on this theory, it can be defined that e-learning is an electronic-based learning media using technology in the form of computers.Regarding disaster preparedness learning, it is hoped that the efor using the e learning model can be seen in the following figure:
