Abstract

This study aims to discover the influence of the Microsoft Teams implementation on students' problem-solving ability by using a problem-based learning model on the harmonic motion topic. This research is conducted in the odd semester of the 2020/2021 academic year. This study applies the experimental method. The study takes place at SMA Negeri 1 Popayato in grade XI with research subjects are XI IPA 1 graders amounted to 20 students’ and XI IPA 3 graders amounted to 20 students. The data collection uses were the assessment of students' test results. However, the data analysis in this study uses the t-test. Based on the hypothesis test, it is obtained that  8.340 greater than  2.024 with a significance level of α = 0.05, then Ho was rejected and H1 was accepted, so it can be concluded that there is a significant effect on students' problem-solving abilities using Microsoft Teams on the Problem Based Learning model.

Abstract

This study aims to determine the significant effect of WhatsApp based on Google Classroom and Google Meet with the implementation of the inquiry learning model in physics learning on student learning outcomes. The research was conducted during the Covid-19 pandemic with a DARING learning process, the method used was the pre-experimental method with one group pretest-posttest design. This research was conducted at SMA Negeri 1 Suwawa in the academic year 2020/2021 using saturated sampling technique and random selection of classes, obtained by students of class XI IPA 1 as an experimental class, class XI IPA 3 as replication class 1, XI IPA 4 as class replication 2 and class XI IPA 2 as replication class 3. The research instrument is in the form of an essay test of 8 numbers on the Dynamics of Rotation and Sturdy Object Balance with a KKM of 73. Based on the results of hypothesis testing, it is known that the t value for each experimental class is replication class 1, replication class 2, and replication class 3 are 4.16, 3.089. , 3.19, 3.386 greater than t table 1.705, 1.739, 1.71, 1.72, it can be concluded that there is a significant positive effect of treatment. Based on the analysis of the N-Gain and the effect size, the N-Gain value for the four classes, respectively, is 0.61, 0.59.0.59, and 0.62 in the medium category, for the effect size value is 1.9 with strong effect interpretation. This shows that there is consistency in the treatment given to student learning outcomes.

Abstract

This experiment aimed to measurenment of the electricity and dielectric characteristic of onion (Allium cepa). In this study, the onion have been done through the variation of frequency and temperature. The frequency was setup in 30 different values from 100 Hz -1 MHz with the temperature are from 26 0 C up to 40 0C with each increase of 2 0C. The measurement was performed on AC current in 1 kHz and input voltage is one volt. The ions through to the membrane was measured as a conductance value by using LCRmeter that connected with two pieces of AgCl electrodes on both side of the membrane. Beside that, the conductance (G) was measured by the variation temperature of the solution. The results based on the electric characteristics variation of the frequency shows that the electricity of the onion membrane from the conductance itself is tend to increase and the capacitance is decrease due to increasing of the frequency. However, the conductance and the capacitance of the soaked onion membrane is increase doe to increase of the temperature than the original onion membrane. In adddition, the increasing of conductance to temperature was plotted on ln G to 1/T curve. The slope or gradient of the curve is used to determine the change of the self-energy of the membrane and its pore radius. Self-energy of ion which obtained from non-washed and washed and soaked (with distilled water) membrane is respectively 7,66967 x 10-21 J or  0,04787 eV dan 1,2156 x 10-19 J or  0,7869 eV ( 1 joule = 6,2415 x 1018 eV) and the average of pore membrane radius is 2,00 x 10-9 meter (2,00 nm) and 1,26 10-10 meter (0,126 nm). Based on the results the onion membrane could be a good membrane for established the electrisity anf the dielectricity.
