Abstract

This research brings innovation to the motion and navigation system of the ‘DK-ONE’ robot. In the 2021 Indonesian ‘Search and Rescue’ robot contest, the ‘DK-ONE’ robot faced difficulties moving towards the target room. The issue was attributed to an unbalanced frame construction and friction between the robot’s legs and the arena floor, leading to leg slippage. This resulted in a mismatch between the programmed number of steps for the robot and the desired path to the target space, causing errors in the robot’s system. To address these problems, researchers conducted a study aimed at enabling the ‘DK-ONE’ robot to accurately determine its direction of motion. This research followed the waterfall method, involving stages such as system analysis, design, coding, testing, and supporting phases. The study was carried out in the integrated laboratory of the Department of Electrical Engineering Education. The development of the robot’s motion direction using a compass sensor significantly improved stability while walking on straight, flat, and uneven paths. The robot no longer experienced errors in its motion direction and remained on the intended path. As a result, the increased efficiency in robot motion also positively impacted the structural efficiency and energy consumption of the robot.

Abstract

The purpose of this study is to determine the relationship between student participation in the activities of the Department Student Association (MHJ) and Student Learning Achievement. The object of research was students of the Department of Mechanical Engineering Education with a total sample of 65 students. The statistics used are non-parametric statistics with analysis using Chi Squared. The results of the analysis showed that there was no relationship between student participation in HMJ activities and the learning achievements achieved by students with the proven calculation results which showed that the chi squared count was smaller than the chi squared table (χ2calculate = 0.764 < χ2table = 9.94). The conclusion is that students can participate in all HMJ activities while running lectures to get good or excellent learning achievements.
