Abstract

Therefore, a tool is needed to make it easier for researchers, so there is no need to go back and forth to retrieve data. This research has the following research method stages, (1) literature study of theories to design the system from the tools to be made, (2) system design, (3) analysis of device requirements, (4) tool calibration process (data can be said to be valid if the error does not exceed one per cent), and (5) data processing is according to agricultural research needs. In this research, a tool that has calibrated with an appropriate measuring instrument produced. Measuring temperature, humidity, and light intensity designed with a microcontroller and other sensors with a data storage base on an SD card. The measuring results show that the temperature values fluctuate between 16.9 °C to 28.2 °C. The value of air humidity tends to remain at the value of 99.9 per cent. At the same time, the value of light intensity ranges from 332 to 606 Cd. The relative error of temperature, humidity, and light intensity is 0.007, 0.082, and 0.016 per cent respectively. Therefore, each measurement indicator has a relative error value of less than one per cent so that the designed tool has valid and under the standardized measuring instrument.DOI: 10.17977/um024v6i12021p033

Abstract

Natural Science is a subject on junior high school level, consist of Physics and Biology. As the characteristic of contextual, natural science has many parts to be explained by observation, presenting the real object both in reality or virtually. As the pandemic era, the learning process difficult to held the real presenting, and virtual approach is the answer of this challenge. Video is one of the teaching and learning media for online learning. In visual model, the video completes with the visualization of particular process or particular object which difficult to direct observe like planets in universe. Furthermore, this particular study aimed to measure the students’ achievement and compare to traditional learning held in offline setting. The students’ achievement represents with the final test in the end of semester. The variables measured in a whole semester with 119 students in junior high level. Besides, the semester with videos for online learning compare to the achievement in the offline semester on same students. As the results, the students’ achievement with the set of visual model videos better than the traditional instruction. After more, this finding can use as the alternative method in online learning due to the continuing pandemic era in Indonesia with extend the study from home program.
