Abstract

This study aims to analyze the validity aspects of a digital module based on the local wisdom of cocoa coffee that has been developed. The research method used is the R and D (Research and Development) research method with the Four-D development model (Define, Design, Develop, Disseminate). In the 4D development stage, in the Develop section, module development and validation activities are carried out by three media and material experts. The data collection technique used a validation questionnaire. The data analysis technique used descriptive analysis. The validation results for each aspect are 86.06% construct validation, 91.11% content validation, and 87.78% language validation, and these three aspects are in the very good category. The overall validation results show that the digital module based on local wisdom of cocoa coffee reaches a validity score of 88.32% which is in the very good category and is feasible to use. Thus, it can be concluded that the digital module based on the local wisdom of cocoa coffee can then be used in the physics learning process in high school as an alternative solution for innovative learning resources based on local wisdom.

Abstract

Practicum tools are learning media that can increase students' interest and motivation to learn. The practicum tool itself is very effective and efficient in supporting physics learning. The magnetic field is related to electricity and magnetism because the magnetic field is generated by an electric current, there is a transfer of charge because the magnet creates a magnetic field around the magnetic charge. Hall effect sensors are used to measure magnetic fields. The purpose of this research is to assist students in understanding magnetism material and also to fulfill the availability of practicum tools in schools, especially SMA/MA. This research uses a type of quantitative descriptive research. The measurement results in the experiment are whether there is a magnet or not, that is, if the solenoid is brought closer, the LED light will turn on, which means there is a magnet and vice versa, if the solenoid is kept away, the LED light turns off, which means there is no magnetic field. In the experiment, the effect of the number of turns shows that the more the number of turns, the greater the magnetic field. The third experiment is the effect of current with 3 experiments with different current values and the same number of turns, the result is that the greater the current, the greater the magnetic field value. This shows that the results are appropriate and valid and can be used as a physics practicum tool.
