Abstract

One of the courses in the Physics Education Study Program that requires direct observation in the field is Advanced Earth Physics. In this course there is one subject that discusses about Groundwater. This study aims to develop a geoelectrical resistivity equipment that can be used in field work by students of the Riau University Physics Education Study Program. The method used was the Research and Development method. The need for tools was analyzed so that ideas for making tools emerge. The tool is designed in such a way as to consider the level of safety, ease of use and antil the acuracy. The results showed that the tools developed were successfully made well. The equipment was validated by experts and field tested. Four experts of Physics lecturers gave an average rating of 3.7on a scale of 4. Thus this tool can already be used in Advanced Earth Physics lectures in the Physics Education Study Program at the University of Riau.

Abstract

In Advanced Earth Physics courses, one of the topics discussed is the characteristics of the earth. One of the topic deals with how to measure the radius of the earth. The purpose of this study is to provide an experiment for students so they can understand how to measure the radius of the earth. A simple but accurate method for measuring the radius of the Earth using a video camera is explained in this study. A demonstration is given to students. Then students were requaired to make their own observations and calculate the radius of the earth obtained from each experiment. The results of student experiments show that the radius of the earth is 6243.94 km with a standard deviation of 14.70 km. The average results of these 35 students are within 1.9% of the average value of the earth's radius which is currently accepted at 6371 km. This experiment is very useful in giving students a good understanding so they understand how to determine the radius of the earth.
