Abstract

The tipping bucket rain gauge is an automatic rain gauge that can measure rain intensity in mm/hour. Accurate measurement of rain intensity requires calibration of the rain gauge to ensure traceability. Calibration of a tipping bucket rain gauge is related to the volume of water as a calibration medium and time so as to produce a discharge that can be converted into rain intensity. Technological developments can make tipping bucket rain gauge calibration automatic by utilizing an Arduino Mega2560 microcontroller, a load cell and a simple water sensor based on the LM393 comparator IC, and combined with a compact design printed using a three-dimensional printer so that it can be used for ex-situ calibration. The data produced by this tool can be downloaded via the application that was built and produces a file in Excel form.

Abstract

The integration of interactive digital media in physics learning is essential to address students’ difficulties in understanding abstract concepts such as light waves. This study aims to develop and evaluate interactive learning media assisted by Google Sites for light wave material. The research employed a Research and Development approach using the ADDIE model. The participants were 31 twelfth-grade students and one physics teacher. Data were collected using validation sheets, learning outcomes tests, motivation questionnaires, and response questionnaires. The results indicated that the developed media met the criteria of validity, effectiveness, and practicality. The average validity score reached 97.31%, while the classical completeness of learning outcomes was 96.77% with a mean score of 85.87. Students’ learning motivation increased by 18.72%, supported by the Wilcoxon test showing that all students experienced improvement. The practicality was reflected in positive responses from students (83.14%) and teachers (100%). These findings demonstrate that Google Sites-assisted interactive media effectively enhances students’ conceptual understanding and learning motivation, particularly in learning abstract physics concepts, and supports the implementation of student-centered learning in the digital era.
