Abstract

The most commonly used method for measuring the density of liquids is based on Archimedes' law. Lubricating oil generally has a defined density standard to show the quality of the oil. The purpose of this study is to determine oil density simply by applying Archimedes' law. This research was conducted in three steps. First, the measurement of the empty pycnometer. Second, the measurement of the pycnometer mass containing distilled water and oil. Third, measurement of copper mass in the medium of air, distilled water and oil. From the results of measurements and calculations, the obtained density of distilled water is (0.995 ± 3,582 x 10-4) gr/cm3 whose value is very close to the value of 1 gr/cm3 so that the distilled water used in this study is suitable as a reference/standard in finding volume copper; oil density is (0.868 ± 2.14 x 10-3) gr/cm3 whose value is very close to the value of oil density measured and calculated with a pycnometer of (0.875 ± 4.637 x 10-4) gr/cm3.

Abstract

COVID-19 virus have affected educational activities to be carried out through e-learning. Discord and Google Jamboard offer advantages in delivering synchronous e-learning. The purpose of this research is to implement e-learning of Physics 1 course using Discord integrated with Google Jamboard and Powerpoint. In this research, we used qualitative-descriptive method which conducted in several steps, i.e: (1) Discord installation and Physics 1 Class preparation; (2) Virtual Tablet Server installation and its testing for mobile phone; (3) Learning materials preparation in Powerpoint; (4) Implementation of Physics 1 Class using Discord integrated with Google Jamboard and Powerpoint; (5) Evaluation of the results and (6) Surveying of student’s opinion about e-learning using using Discord integrated with Google Jamboard and Powerpoint. Discord can be used as an alternative e-learning tool because of its practical use as well as more powerful when integrated with Google Jamboard and Powerpoint, especially for mathematical-analytics subject such as Physics. This is supported by the results of a survey in which 34 out of 39 students said they wanted to use Discord and Google Jamboard for other mathematical-analytics subjects.
