Abstract

This research is a Research and Development (R&D) research. This development was carried out with the steps put forward by Borg & Gall. The development procedure for Borg & Gall consists of ten stages, but this research was carried out through stage seven, namely Operating Product Revision. The research instruments were validation sheets, assessment sheets, student response sheets, and performance sheets. Product quality assessment uses a Likert scale made in the form of a checklist. Evaluation of students' responses and feasibility sheets using the Guttman scale made in the form of a checklist. Tool testing is done to determine the accuracy and precision of the product. The results of this study are arduino uno-based straight motion practicum along with LKPD. Product quality based on the assessment of media experts, material experts, and physics teachers has very good quality (SB) with a score of 3.71, 3.67, and 3.58. Students' responses to the product in preliminary field testing in the form of practicum and LKPD tool kits showed an agreed response with a score of 0.85 for LKPD and a score of 1 for practicum tools. The score is included in the agreed category. Examination test on main field testing found that in practicum activities students can use tools smoothly, students can actively discuss, and tools developed can run without obstacles. The results of the Arduino uno-based straight motion practicum test results were found to have a precision of 96.75% for an angle of 20 degrees and 96.47% for an angle of 30 degrees, for accuracy found results of 94.24% for an angle of 20 degrees and 91.06 % for a 30 degree angle.
