Level Pemahaman Konsep Fluida Mahasiswa Calon Guru Fisika dalam Project Based Laboratory (PJB-Lab)
No full textUnderstanding Physics Concepts is a concern for every learning process and physics practicum. The development of various physics practicum concepts in the Inquiry Lab or Project Based Lab models contributes to the Students' Concept Understanding Level. This study was conducted to determine the level of conceptual understanding of students on the concept of fluid through project-based laboratory. The method used is pre-experimental with one group pretest and posttest design. The subjects of this study were 22 prospective physics teacher students at one of the universities in Banda Aceh City. The test instrument used is a level test of concept understanding in the form of a stratified description consisting of the ability to explain the concept (P), the ability to determine the laws of physics (Q), ability to provide additional case examples of related laws (R) and define those laws (S). The results showed that students achieved an understanding of fluid concepts at the level of complete understanding (CU) after participating in a project-based laboratory. Therefore, it can be concluded that the level of understanding of physics concepts effectively increases to achieve complete understanding through project-based laboratory
Pengukuran Kecerahan Langit Arah Zenit di Medan dan Serdang Bedagai Menggunakan Sky Quality Meter
No full textLight pollution is a worldwide problem that affects fewer stars that can be seen at night. This study aims to measure the brightness of the sky in the zenith direction to minimize the effect of light pollution in observing celestial bodies. The research used the observation method of sky brightness level with SQM. Measurement of sky brightness was carried out in two places, namely in Medan and Serdang Bedagai. The SQM is mounted in a zenith direction and set to retrieve data every two seconds. Observations were made on November 10-13, 2018, during the new moon phase. The average value of sky brightness obtained in Medan is 18.05 mpsas and the NELM value is 4.00. Based on the Bortle scale, Medan is included in the ninth class area, namely the inner-city sky. Meanwhile, the average value of sky brightness obtained in Serdang Bedagai is 19.69 mpsas and the NELM value is 5.26. Based on the Bortle scale, Serdang Bedagai belongs to the sixth class area, namely bright suburban sky

The research method used descriptive method and data collection techniques using a survey through Google Form. The research subjects were Grade X,XI,XII . The results showed that the skill of students’ self regulation was in the high category with presentage of 17%, medium category 69% and high catogory 14%. Based on three components of self-regulation, majority of students were in medium category (cognitive 66%, behavior 62% dan motivation 50%). Analysis also have done to measure the skill of students’ self regulation before and after online learning. Majority of the students were ini medium category (preparation 76%, implementation 53%, reflection 64%). The result of the reasearch show that the students need more effort to enhance the skill of self regulation, to be success in online learning
Desain Pembelajaran Jarak Jauh Berbasis E-Learning pada Pelajaran Fisika SMA
No full textThe background of this research is the existence of globalization which makes education very important for all people. One way to significantly expand access to education is through distance learning (PJJ). PJJ can provide comfort for students to study independently anywhere and anytime. The implementation of PJJ has been widely carried out using LMS (Learning Management System). The purpose of this research is to produce a distance learning design based on e-learning on valid and practical temperature and heat material. This research uses mix method research with ADDIE development model. There are two subjects in this study, namely learning design in google classroom and students of class XI MIPA 1 SMA Negeri 15 Palembang, totaling 36 students. Instruments in this study were validation and practicality sheets and interviews. The results of the media and material validation questionnaire analysis as well as the media practicality questionnaire in the study obtained an average media validation score of 3.67 or 91.75%, the average material validation score obtained 3.31 or 82.75% and practicality questionnaire analysis got 3.13 or 78.07% , this shows that these media and materials are feasible and practical to use
Pengukuran Ketepatan Alignment Sistem Penjejak Gerak Benda Langit dengan Metode Drift Berbantuan Tracker
No full textThe simulation of the drift method application using a celestial body tracker has been done. Experiments were carried out by recording the movement of a celestial body tracker with variation orientation of polar angle and azimuth from the true south and polar angle a particular location. The variation is between -2° to +2°. It was found that the greater the difference in the mounting orientation from the true orientation, the greater the shift in altitude and azimuth of the celestial object’s path

No full textIn this research, a light efficiency test tool has been designed using an Arduino UNO microcontroller to provide an understanding of the use of the ohm law application in basic physics practicum. This lamp efficiency test prototype uses an LDR sensor device and a resistor connected to the Arduino microcontroller as a light intensity detector, while the variation of electrical power is used by an AC variac with the lamp distance to the sensor having a constant value. The experimental results showed that the efficiency of the lamp can be obtained through a gradient of the luminosity curve on electric power. The efficiency of the lamp is 16.935 lm/watt and the average resistance can be obtained on 983.01 which the intensity in lux is 337,05 lux on 157,68 Lm and the maximum intensity in lux can be obtained on 453,35 lux on 208,54 Lm
Analisis Dinamika Stroller (Kereta Bayi) dengan Metode Port-Controlled Hamiltonian System (PCHS) berbasis Komputasi Fisika
No full textComputational physics can be used to help solve complex dynamics equations, both translational and rotational. The purpose of this study is to obtain differences in the dynamics of mechanical systems with non-holonomic constraints in various flat and curved configuration spaces based on physics computing. In this study the reduction used is a mathematical calculation of the Port-Contolled Hamiltonian System (PCHS) equation in a mechanical system that is a Stroller, so that the equation used in determining the Stroller motion equation with and without friction that moves in the curved plane in the form of a spherical surface with various initial conditions based on maple is Poincaré's equation which is based on Routhian reduction with and without friction. The effect of friction can be clearly seen through dynamics and graphical equations on the Stroller. This method can reduce the Stroller motion equation with and without friction that moves on the ball sphere clearly in the form of a set of differential equations. The findings of this study are dynamic equations and graphs of Stroller equations with and without friction that move in the curved plane in the form of a spherical ball with varying initial conditions based on maples. This study proves physical concepts about dynamics and kinematics and analyzes Stroller dynamics using computational physics to determine the characteristics of complex and complex Stroller movements, both translational and rotational
