Abstract

A good understanding of the labeling of the positions of celestial bodies, including the Sun, in a horizontal coordinate system, is absolutely necessary as a basis for understanding astronomy and astrophysics. The existence of media that can be used to provide simulations of the celestial sphere and its coordinate system is very important to support the learning process. Through this quantitative descriptive statistical research with One-Group Pretest-Posttest Design, it can be shown that the use of Digistar 6-Based Planetarium as an educational medium can improve students' understanding of the position of the Sun in a horizontal coordinate system. The increase in understanding was marked by an increase in the average percentage of correct answers from pretest to posttest by 32.89%, an increase in the percentage of minimum and maximum correct answers by 54% and 60%, respectively, and an increase in the number of passes in the PAP version by 53.34%.

Abstract

The use of appropriate media is minimal in physics learning today, which impacts students' lack of motivation and indirectly affects their learning outcomes. A direct learning model with interactive multimedia is an alternative solution during the current pandemic. This study aims to improve students' understanding of physics concepts by applying a direct learning model with interactive multimedia. This is a quasi-experimental research with a pretest-posttest control group design using a purposive sampling technique. Forty-five respondents were divided into two groups, experimental and control. N-Gain was used to determine the high increase in both groups. The test was used to collect data on students' conceptual understanding in the form of a description with a total of 5 questions. In addition to the N-Gain, a t-test was also conducted to test the mean difference of the data. The findings revealed that the understanding of the concepts of the two groups had increased, where the experimental group was 40.3, and the control group was 35.8 but did not differ significantly. It can be concluded that the understanding of the fluid concept of the experimental class students is not better than the control class students.

Abstract

Factors that affect the growth of catfish include water temperature, pH levels, and feeding according to the growth of catfish. Feeding and water replacement are currently still done manually, using human power. Maintaining feed and water quality in the tub automatically is necessary to save time and effort. The automatic settings to maintain feed and water temperature as well as good water acidity for catfish in the tub can use the NodeMCU microcontroller. This research method is carried out by designing tools, testing tools, objects and stages of tools and concluding. Parameters of water temperature and pH levels of water are sent to the telegram application, as well as to regulate the discharge of water, a pump that works automatically is used through a relay that is installed automatically. The monitoring results are successfully displayed via the ThingViewer application. The tool has worked well with tests carried out including testing the design of the tool, testing the temperature sensor, testing the pH sensor, and testing the sending of orders from Telegram. The yields obtained were different between the two treatments, namely without using tools (non-tools) using tools (tools), the ideal growth of catfish for a temperature of 29 °C and a minimum pH of 6.5 and a maximum of 9.
