Pemerintah China dan dunia selama masa pandemi COVID-19 memutuskan menutup sekolah secara nasional dan mengharuskan siswa untuk belajar online dari rumah. Artikel ini memiliki tujuan untuk menunjukkan problematika pembelajaran di era pandemi dan rekomendasinya. Studi literatur digunakan untuk mendeskripsikan berbagai problematika pembelajaran di era pandemi. Metode penelitian yang digunakan pada penelitian ini adalah kualitatif dengan pendekatan studi kepustakaan (library research) dengan cara mengumpulkan data dari berbagai sumber literatur. Proses pengumpulan data artikel melalui open access website Google Scholar dan Scopus dengan tahun terbit 2020 hingga 2022. Proses pencarian literatur dimulai frasa kunci utama “pandemi Covid 19”, “pendidikan” dan “sekolah”. Studi literatur menggunakan 29 artikel untuk mendeskripsikan berbagai problematika pembelajaran di era pandemi. Pencarian literatur selama pandemi di berbagai negara dilakukan sebagai pendukung paper. Problematika psikologis merupakan yang terbanyak sekitar 80% dan sisanya kesehatan fisik Saat sekolah sudah kembali dibuka, pemulihan harus dilakukan dengan cepat dan tepat dengan alokasi dana tepat guna. Disimpulkan bahwa sekolah harus membudayakan cuci tangan yang ketat sebelum dan setelah makan menggunakan sabun dan air. Perlu merancang kursus konseling kelompok untuk psikologi siswa terhadap trauma serta untuk meningkatkan ketahanan siswa selama masa pandemi. Model pembelajaran daring dapat digabungkan dengan pembelajaran luring sehingga akan mengatasi kekurangan masing-masing model pembelajaran pada saat sekolah sudah kembali dibuka.

The philosophy of existentialism emerged driven by the uncertain world conditions due to world wars. So existentialism is present as a thought movement that emphasizes human subjectivity and freedom. This study has a purpose for reflection. Reflection means the process of understanding events in the mind or experience that is owned. This study uses descriptive qualitative research. This study utilizes a literature search. The literature search process begins with key phrases such as “existentialism”, “education” and “awareness”. Man must exist, which means realizing that he exists to control himself and act on his behalf. The philosophy of existentialism talks about human existence, while talking about humans means questioning educational issues. Each person is unique, which is different from one another. Realizing this is important for students, parents, teachers, principals, board members, and all those involved in education. Education is expected to realize the "intensity of awareness" of students. So that they are aware of their responsibility to determine the life they will live themselves.

Education today is required to utilize technological knowledge and skills in preparation for global competition. Along with the rapid development of technology, educators are required to develop learning alternatives. The purpose of this research is to create a particle trajectory simulation that is used as an alternative to online learning. The simulation uses Python programming language and Origin Pro assisted spreadsheet. Simulation in Python programming uses the Euler Cromer method to describe particle trajectories affected by electric and magnetic fields. This paper has successfully simulated particle trajectories affected by electric and magnetic fields with the Python programming language and Spreadsheet. The case where the motion of a charged particle is affected by a combination of electric and magnetic fields is when a positively charged particle moves perpendicular to the magnetic field, it will form a helical trajectory. However, when the electric field is in the direction of the magnetic field, the motion in the direction of the magnetic field will be accelerated by the electric force in the direction of the magnetic field which causes the helix to increase in width.
