Paper ini memiliki tujuan mendeskripsikan solusi terhadap masalah yang terjadi selama pandemi COVID-19 di Indonesia seperti bias kognitif, kesenjangan digital dan moral saat pandemi COVID-19 melanda. Paper ini bersifat deskriptif dengan pengumpulan data berbagai literatur. Fenomena masyarakat yang tidak peduli dengan kondisi pandemi disebabkan oleh rendahnya kemampuan literasi sehingga terjadi bias kognitif. Perbaikan teknologi informasi terutama didaerah pedesaan perlu diperhatikan mengingat terjadinya kesenjangan digital. Dalam upaya menangani masalah moral yang terjadi pendidikan karakter yang menjadi kunci utama bangsa Indonesia. Pendidikan karakter dapat dimulai dari keluarga masingmasing sehingga dapat terwujud generasi bangsa yang memiliki akhlak mulia dan berkepribadian Indonesia.

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....

Therefore, it is necessary to have technology-based simulations to understand physical phenomena. One technology that is easy to use for simulations in physics learning is the spreadsheet program. This study aims to use spreadsheet media to visualize the face-centered cubic (FCC) energy band using the tight-binding method and to compare the results with the JavaScript programming language. This paper succeeded in making visualization of face-centered cubic (FCC) energy band using a spreadsheet as an alternative to distance learning. The spreadsheet is easier to use because they do not use complicated programming languages like JavaScript. This paper shows the use of innovative learning media, spreadsheets, in materials courses.

The research aims to design a water surface-level detection system by using ultrasonic sensors and the ESP8266- 12E module. The tools and materials used during the design are: Ultrasonic sensors HC-SR04, module ESP8266-12E, and buzzer as an output to sound the alarm. The ultrasonic HC-SR04 sensor will detect the water surface level, the detection data will be sent to the ESP8266-12E module, then the system will send the information in the form of a message through telegram and buzzer application. The messages delivered are several stages including standby, alert, and danger. The methods used in this design are planning, study libraries, collection of tools and materials, hardware plan, and program creation on the software. The final result is a system capable of detecting water surface level based on the ult...

Kerusakan banyak terjadi di daerah sedimen Yogyakarta daripada di perbukitan Wonosari yang memiliki lapisan lebih keras. Kerusakan ini mengindikasikan adanya kontrol efek tapak lokal. Penelitian ini bertujuan untuk memetakan daerah rawan kerusakan gempabumi di Kotamadya Yogyakarta berdasarkan analisis kurva Horizontal-to-Vertical Spectral Ratio (HVSR) dan mengetahui litologi bawah permukaan berdasarkan ground profiles kecepatan gelombang geser (Vs) dengan metode inversi kurva HVSR. Penelitian dilakukan di Kotamadya Yogyakarta dan sekitarnya yang dibatasi pada koordinat 7o45’58.09’’- 7o50’59.01’’ Lintang Selatan dan 110o19’7.87’’-110o24’35.43’’ Bujur Timur. Data mikrotremor sebanyak 280 diolah menggunakan metode HVSR. Proses inversi HVSR juga dilakukan untuk memperkirakan model perlapisan tanah. Hasil dari penelitian menunjukkan bahwa ...

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...
