Abstract

In this study, Fluxgate made with a design 30 and 20 winding excitation coil pickups. Fluxgate used to measure vibrations in two dimensions. Vibration measurements performed indirectly by using two mechanical pendulum to vibrate in the direction of axis x and y are placed on the source of vibration. Fluxgate sensor working principle is developed when there is vibration, then the magnetic mass at the end of the pendulum arm will come to move in rhythm with the vibration. This will result in the distance between the sensor with a magnetic mass changes. Changes in this distance will lead to changes in magnetic induction at the core of the sensor. Because of the large magnetic field intensity received by the sensor varies with the distance the vibration amplitude changes that occur will result in a change in voltage generated by the sensor. This means that the emf is happening is a function of the distance between the sensor with a magnetic mass. Fluxgate sensor is placed in the direction of axis x and y. Based on analysis of data obtained sensitivity of the sensor x and y with the same value that is ± 39 mV / μT. The range of frequencies that can be detected by sensors in this study were 0.37 Hz to 1.81 Hz and amplitude range that has been carried out ranging between 0.7 cm to 2.3 cm. Maximum absolute error and maximum relative error in the characterization of the frequency obtained is happening on the sensor y of 0.054 Hz and -2.18%. For amplitude obtained is happening on the sensor x 0,005 volt and 3,28%.

Abstract

Media digital memainkan peran krusial dalam mengembangkan kemampuan berpikir kritis dalam pembelajaran sains di sekolah dasar pada abad ke-21. Penelitian ini bertujuan untuk mengeksplorasi dampak penggunaan media digital dalam meningkatkan keterampilan berpikir kritis siswa. Metode penelitian literatur review dilakukan dengan analisis berbagai buku, dan jurnal, di mana siswa diperkenalkan dengan pembelajaran IPA melalui berbagai media digital interaktif. Dalam konteks ini, penerapan media digital dalam pembelajaran IPA di sekolah dasar tidak hanya membantu siswa memahami konsep-konsep ilmiah, tetapi juga memberdayakan mereka dengan keterampilan berpikir kritis yang esensial untuk menghadapi tuntutan dunia abad ke-21. Implikasi dari temuan ini dapat memberikan dasar bagi pengembangan strategi pembelajaran yang lebih inovatif dan relevan di masa depan.

Abstract

The research objective is to understand the learning motivation of Tadris IPA students at UIN Imam Bonjol Padang in online learning. The sample in the survey research is 36 students of Tadris IPA with data collection in the form of a motivational aspect questionnaire containing 10 statements via google form. Questionnaire analysis shows that the average aspect of motivation is 84% ??(very high motivation). It can be concluded that the Tadris IPA students of UIN Imam Bonjol Padang are very motivated to learn during online learning.
