Abstract

The National Achievement Center (Puspresnas) and the Ministry of Education and Culture of the Republic of Indonesia proudly present the Indonesian Ash Robot Contest (KRAI), a yearly student robotics competition where teams tackle ash-related challenges with their robot creations. At KRAI 2021, it was shown that many robots were controlled using joysticks and resulted in a lack of effectiveness in robotic motion. The use of a joystick makes the movement of the robot take longer. This is because the robot is controlled by humans and the robot has not been able to pinpoint the robot's location. Gyrodometry is a method to map the robot's position using a inner ear and compass of the machine. In this research, Gyrodometry is used to map the position based on the readings of the gyroscope sensor and rotary encoder so that the robot can move automatically. In this research, the KRAI hitter robot can map positions and move in an accurate direction and can move automatically and effectively so that it can save more time and can increase the possibility of strategy in the match. From the results of this study, it was found that without using gyrodometry the error of X reached 11.825 cm and Y reached 35.1325 cm and also the angle error reached 13.7 degrees. and by using gyrodometry error X reaches 4.25 cm and Y reaches 5.775 cm and angle error 2.01 degrees. From these results, it was found that using gyrodometry was better than without using gyrodometry. The addition of waypoints to the robot only produces an average error of 8.2 cm X and Y error of -7.8 cm and the angle error reaches 10.2 degrees.

Abstract

Underwater Remotely Operated Vehicle (ROV) control system architecture, work Class II - underwater inspection is demonstrated. The object is programmed on MATLAB simulink. The nonlinear modeled plants were processed by approximation way. Author planned a controller of an underwater ROV object. PID controller is used modeled plant. Tuning PID tool is used MATLAB for choose underwater ROV controller. Researchers tested an underwater ROV for system and solving problems an underwater ROV architecture.

Abstract

The rescheduling due to delays in the repair project of two ships being worked on simultaneously was carried out using the Critical Path Method (CPM) and Time Cost Trade Off (TCTO). The data obtained came from the repair lists of each ship. The aim was to expedite project completion and achieve the most optimal time and cost efficiency. Acceleration alternatives were calculated, such as adding labor and extending work hours on the critical path. The acceleration steps included adding 2 and 4 extra working hours and increasing the number of workers. The analysis results showed that the most optimal time reduction was achieved by adding 4 hours of overtime and 21 additional workers, successfully reducing the project duration from 55 days to 20 days, with a time efficiency of 64% and a cost savings from Rp 393,300,000 to Rp 390,330,000, a savings of Rp 2,970,000 or around 0.7%. The daily productivity for scrapping work reached a maximum of 650 m²/day, while the increase in labor and 2 extra working hours resulted in 780 m²/day, and 4 extra working hours resulted in 845 m²/day.
