In this paper, an alternative solution is presented for the discussion of energy band material in Body Centered Cubic (BCC) based on tight binding in distance material physics lectures. These activities take advantage of technology assistance in the form of spreadsheet software. Spreadsheet software is used in this research because it is a computational software that can visualize a graphic according to user commands. The use of spreadsheets is also due to being one of the computational programs that are easy to access, operate, and often used by students, especially during the current conditions affected by the Covid-19 pandemic. This research presents a simple way for students to visualize the energy band from BCC through the spreadsheet assistance. This visualization of the energy bands in BCC begins by describing the appropriate mathematical equation....

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 psikologi...

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...

Penelitian ini dilakukan dengan metode resistivitas konfigurasi dipole-dipole, di Dusun Jetis, Dusun Jati, dan Dusun Dukuh, Desa Gerbosari, Kecamatan Samigaluh, Kabupaten Kulonprogo. Peralatan utama yang digunakan dalam pengambilan data adalah Resistivitymeter (Naniura NRD 22 S). Luas daerah penelitian adalah 1,1 km × 0,5 km dengan jumlah pengukuran sebanyak 3 lintasan dengan lokasi penelitian berada pada koordinat 7o39’45,90’’ LS sampai 7o40’20,94’’ LS dan 110o10’02,79’’ BT sampai 110o10’17,00’’ BT. Metode yang digunakan adalah metode resistivitas yang didasari oleh Hukum Ohm, dengan menginjeksikan arus melalui dua elektroda arus maka dapat diukur beda potensial yang muncul dari elektroda potensial. Hasil pengukuran yang diproses menggunakan software Res2dinv menunjukkan penampang 2D, seb...

The method used is a descriptive quantitative with the research stages including the selection, making, and testing the feasibility of crystal structure. The feasibility of the crystal structure was assessed using a product feasibility test sheet and analyzed using the ideal standard mean equation. The development of a crystal structure model was carried out using a simple and easy method to obtain equipment in the form of molymod. The results of this research indicate that the crystal structure of carbon tetrachloride, diamond, and fullerenes can be interpreted significantly and easily with the help of molymod. The simple model of the crystal structure is also suitable for use as a physics learning medium that can help students understand abstract crystal structure material.
