Pengukuran Konstanta Dielektrik Udara Pada Perangkat Kapasitor Plat-Sejajar Berbasis Mikrokontroler Arduino Uno
No full textThis study aims to design a prototype of an air dielectric constant measuring device and be able to measure the capacitance value using an Arduino microcontroller device. The measurement of the air dielectric constant is carried out by means of the principle of measuring the capacitance of a capacitor device with a plate-parallel configuration with the air dielectric material. Capacitance measurements are carried out with the principle of charging and emptying capacitors using an Arduino Uno microcontroller device. The charging and discharging process is carried out using a series of resistor-capacitor (RC) series with a source voltage of 5 volts from the microcontroller device. This experiment has used a parallel plate with a size of 29 × 30 cm as an electrode capacitor, and a resistor device with a size of 125 megaOhm. The results showed that the behavior of charging and discharging parallel plate capacitor devices has an R square value of> 0.9, which shows a fairly good correlation between the predicted and experimental results on capacitance measurements. The results showed that the prototype of a dielectric constant measuring device can be well designed by showing the capacitance value of the device at the state of filling and emptying and the measurement results show the value of the air dielectric constant has been measured with a value of 0.991 - 1.0346

Keefektifan Virtual Class dengan Google Classroom dalam Pembelajaran Fisika Dimasa Pandemi Covid-19
No full textAt this time, the school is conducting online learning from home due to the Covid-19 pandemic, but teachers and students still do online-based or Virtual Class learning through various applications, one of which is Google Classroom. The implementation of Google Classroom is still very public for learners, because usually teachers teach face-to-face. The purpose of this article is to determine the effectiveness of the Virtual Class implementation with Google Classroom in the Covid-19 pandemic Physics study. The method used in the form of charging poll through the Google Form in junior high school class VII-IX randomly represents one province namely West Java. From the results of a descriptive survey the results of the Google Classroom are less effective in physical learning, but are effective in virtual class learning and can be used as a Covid-19 pandemic learning app. So it can be concluded that students still need teachers directly in the process of learning physics

Analisis Lapisan Batuan dan Potensi Air Tanah dengan Metode Geolistrik Konfigurasi Schlumberger di Kampus 2 UIN Sunan Gunung Djati Bandung
No full textGeoelectric is the method most often used to obtain subsurface images with the possibility of groundwater and minerals at a certain depth. Estimations by means of this method are based on the fact that different materials will have different types of resistance when electrified. The purpose of this research is to estimate the electrical properties of subsurface rock formations, especially their ability to generate electricity or inhibit electricity. The results showed that the tested area had soil geological conditions which were dominated by soil, sand and gravel in the surface area, whereas for 50 m depth it was dominated by sedimentary rocks accompanied by basalt rocks with little saline in the deepest layer. For large resistivity in the range of 3000 - 5000 Wm it indicates that the area has poor groundwater potential

Analisis Persepsi Calon Guru Terhadap Pengembangan Keterampilan Probem Solving Melalui Pembelajaran Fisika
No full textA study about development of problem solving skills in physics learning was conducted to investigate how prospective teachers were able to integrate this ability into physics instruction. This article discusses the responses of prospective teachers to the development of problem solving skills through physics learning. Data were collected by using questionnaires and interviews. To strengthen data obtained through questionnaires, data were analyzed descriptively. The results of the study show that prospective physics teachers who have participated in Field Experience Program 2 (PPL 2) or who are currently participating in PPL 1, in general, agree that problem solving skills can be developed through subject matter learning, especially in physics learning. However, there are some prospective physics teachers who gave anomalous responses to several statements in the questionnaire, for example there are students who do not approve the statement that reads “Facilitating and analyzing problems for problem solving is done by drawing or sketching”. Based on these findings, it is necessary to provide a good understanding of the steps that should be taught in developing problem solving skills, such as giving example or modelling. Furthermore, prospective physics teachers need to be assessed their ability to teach the development of problem solving skills which was integrated with/in physics learning
Perancangan Perancangan Sistem Pengukuran Kapasitansi Crude Oil Menggunakan Interdigital Capasitors (IDCs) Berbasis Arduino Uno
No full textArduino UNO R3 is one of the cheapest and easiest microcontroller boards that has great potential to be used as a basis for the measurement system. This study aims to develop measurement system of crude oil capacitance by using IDCs(Interdigital Capacitors). By knowing the value of crude oil capacitance, the crude oil permittivity value can be calculated. The crude oil permittivity value data is extremely needed in making crude oil heating systems using microwaves. The study used IDC sprinted on a PCB board with a copper layer as the electrode. Then, the system measurement results were compared with the results of PM 6303 RCL meter Phillip type A frequency measurement of 1 kHz which was used as reference data to determine the extent of measurement errors. From the results obtained, it is known that the error value of the Arduino UNO R3 based capacitance repeatability measurement is 0.47%. While the results of the linearity test measurement of crude oil capacitance measurement of temperature increases using the Arduino Uno-based IDCs sensor, the R2 value is 0.87. Thus it can be seen that the Arduino UNO R3-based capacitance measuring device has quite good sensor characteristics
