Abstract

This research aims to make a miniature ore material transfer tool automatically using Omron PLC. The way this tool works is that when the start button is pressed, motor 1 will move the apron containing the ore to be taken to the 3 storage barrels to be filled alternately. In each storage barrel, a proximity sensor is installed to detect the level of ore filling. On the rails that are passed by the apron, there are three limit switches that serve as indicators that the position of the apron is right above the storage barrel, then motor 2 will open the valve on the apron so that the ore on the apron falls into the reservoir. From this research, we have succeeded in obtaining an automatic control system for a miniature material transfer device in the ore distribution process.

Abstract

This study aims to develop a diagnostic test for understanding the concept of sound waves and to test the validity and reliability of the test. The research method used is development research with reference to the ADDIE model (Analyzing, Designing, Developing, Implementing, Evaluating). This research was conducted at a senior high school in the city of Bandung involving 30 students as respondents. The stages of developing a diagnostic test include literature study, needs analysis, formulating competencies and indicators, developing test items, expert validation, test trials, reliability analysis, ease of analysis, discriminating power analysis, and item selection. The validity of the diagnostic test for understanding the concept of sound waves was tested using several techniques, such as content validation and construct validation. While the reliability of the diagnostic test was tested using the K-R.20 calculation. The results showed that the developed diagnostic test for understanding the concept of sound waves had good validity and reliability. This test can be used to measure students' understanding of the concept of sound waves and to identify difficulties experienced by students in understanding the concept.
