Abstract

There have been research which aims to know the development of experimental device for determineof gravity based on the theory of the inclined plane based Microcomputer Based Laboratory (MBL).Gravity is the force of attraction that occurs between all the particles having a mass in the universe. In these experiments using the tools and materials is motion detector, computer, logger pro, ruler, board track, cars, connecting cables, and beams. When the cars is dropped on an incline, then analyzed using logger pro whose data has been computerized. Method of data analysis used was linear regression analysis. The experimental results the value of the gravity in according to with the reference value in the amount of (9,895±0,529) ms-2 with a deviation of 0,91%. Key words: acceleration of gravity, logger pro, MBL, linear regression

Abstract

Science process skills are one of the competencies that must be possessed by students after attending physics learning. Science process skills can be obtained by practicum activities both in person and virtually. However, the availability of virual physics practicum modules is not widely available in schools, even though there are some materials that cannot be done directly.  Therefore, a guided inquiry-based virtual practicum module is needed to improve students' science process skills in learning physics. This development research using 4-D method (Define, Design, Develop, and Disseminate). In the development of this module, the researchers only come to the third stage of the four stages. Validation results from experts get an average score of 86% interpretation which means that the module is included in the criteria worthy of use in learning even with the notes of experts to revise some of the components present in this module so that this module complies with existing standards. The results of the analysis of student responses to the practicum module obtained a total average of 85% with the category is "strong." This shows almost all the students gave a positive response to the virtual practicum module based guided inquiry. The development of virtual practicum modules based guided inquiry can improve science process skills of the students, with the average score of students‟ science process skills before using a virtual practicum module based guided inquiry of 2.63 and the average score of students‟ science process skills after using a virtual practicum module based guided inquiry of 3.30
