The survey results show that geographically the regencies and cities on the coast of West Sumatra are around the threat of a tsunami, in addition to economic activities, government activities, and high population density around the coastal area. Regencies and cities located on the coast of West Sumatra, including West Pasaman Regency, Agam Regency, Padang Pariaman Regency, Pariaman City, Padang City, Pesisir Selatan Regency, and the Mentawai Islands, are feared to be the following places to be hit by a tsunami, for this reason, efforts are needed - efforts to overcome the tsunami hazard. In conclusion, the tsunami risk zone in the province of West Sumatra, which is very dangerous, is in the Mentawai archipelago with a wave height of 20-35 m and a wave arrival time of 10-20 minutes with a warning level of alert. And the story of tsunami disaster risk in coastal districts and cities of West Sumatra province is divided into four zones, namely: Not dangerous, Less dangerous, namely West Pasaman district, the danger is Agam district, Pariaman city, Padang Pariaman district, Padang city, and Pesisir Selatan district, Very dangerous namely the Mentawai Islands. \u0000  \u0000Keywords: ArcGis 10.3, Comcot, Tsunami","PeriodicalId":187448,"journal":{"name":"Science, and Physics Education Journal (SPEJ)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126200260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spreadsheet is used to solve the analytical solution of the system of particle motion in the electromagnetic field. The results show that the graph plot of the numerical solution is immediately visible as a simulation of the trajectory of particles in an electromagnetic field. The simulation results show that the course of charged particles in an electromagnetic field depends on the strength of the electric field, magnetic field, particle mass, particle charge, initial velocity, and the angle between the electric field and magnetic field. Simulations developed using spreadsheets can be a powerful pedagogical tool in the study of physics. In conclusion, simulations using excel, as discussed above, appear to help students better understand the mathematical principles underlying physical phenomena and better appreciate the power of mathematics applied to the real world. The simulations generated in this study show that even without using macros, we can create sophisticated simulations. \u0000  \u0000Keywords: Electromagnetic Field, Simulation, Spreadsheets","PeriodicalId":187448,"journal":{"name":"Science, and Physics Education Journal (SPEJ)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121726237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
