Abstract

The problem with this boiler is that the steam produced is not continuous, meaning that at a pressure of 1 bar, thesteam lasts for approximately 2 minutes, and the heating process of this fire-tube boiler is also prolonged, taking around 95minutes from the start until reaching a temperature of 100°C. This results in the need for more used oil as fuel. Some initialanalyses to solve these issues include increasing the heating surface area of the boiler or the combustion chamber by adding watertubes and using wood as the fuel. The objective of this research is to analyze the heating time, steam retention time, wood f uelconsumption, and efficiency before and after the modification with the addition of water tubes. The method used is experiment al.The tests conducted before modification showed a heating time of 45 minutes, and with the addition of water tubes, the heatingtime was reduced to 36 minutes. The steam retention time before modification was 4 minutes, while with the addition of watertubes, it increased to 4 minutes and 42 seconds. The total wood fuel consumption for the fire-tube boiler to reach an operatingpressure of 3 bar required 33.2 kg of wood, and after the addition of water tubes, the total consumption to reach 3 bar wasreduced to 27 kg of wood. The efficiency of the fire-tube boiler before modification at 1 bar pressure was 66.6%, at 2 barpressure 59.3%, and at 3 bar pressure 51.6%. After adding water tubes to the fire-tube boiler, the efficiency increased, with theefficiency at 1 bar pressure being 74.5%, at 2 bar pressure 68.8%, and at 3 bar pressure 62.9%. This indicates that the addition ofwater tubes can improve the boiler's efficiency.

Abstract

The maneuverability and precision of three-wheeled omniwheel robots are essential for effective navigation invarious environments. This study aims to implement a PID (Proportional-Integral-Derivative) control system on a threewheeled omniwheel robot using the arduino platform, with compass sensor data serving as the primary reference fororientation control. The omniwheel design allows the robot to move freely in any direction, making it suitable forapplications that require high flexibility and responsiveness. In this research, mathematical modeling of the robot'sdynamics was conducted to understand its behavior during movement. The PID control algorithm was implemented tomanage the speed and angular velocity of each wheel, utilizing feedback from the compass sensor to maintain the desiredheading and stability during maneuvers. The experimental setup involved various maneuver scenarios, including rapiddirection changes and navigation through complex paths. Results indicate that the integration of PID control withcompass data significantly enhances the stability and accuracy of the robot's maneuvers. The proposed control systemeffectively reduces heading error and improves response time, demonstrating its effectiveness in maintaining precisemovement under dynamic conditions. In conclusion, the combination of Arduino platform, PID control, and compassdata provides a robust solution for controlling the main maneuver of a three-wheeled omniwheel robot, particularly inapplications demanding high maneuverability and directional stability.
