Abstract

The completion of autonomous surface vehicle water missions is required to have adaptive capabilities in maintaining the position, attitude or tilt, and stability of the ship against the influence of external disturbances that can interfere with the ASV's navigation system. Therefore, this research focuses on the orientation holding control system against external disturbances. To determine the value of the angular shift or tilt of the ship's facing direction using the CMPS14 sensor. The control method used to determine the ship's propulsion response in determining the speed based on the heading error value and the amount of rotation speed through the bow thruster in maintaining the ship's heading using the ANFIS (Adaptive Neuro-Fuzzy Inference System) Method. The ANFIS model that has been made for predicting the value has an RMSE value of 1.6169% which is then implemented on a microcontroller with conversion and has an accuracy value of 99,6%. In testing the performance of the ship orientation control system by giving 10 variations of disturbance shows an average response time of 5.08 seconds. So that the application of the ANFIS method in this control system has good performance and can be used as a reference for further research.

Abstract

Traditional fishing boats are used widely by fishermen in Indonesia. However, the design has not been standardized yet. Therefore, it will influence the resistance and the endurance tests. In this study, we aim to design the lines plan model of a fishing boat for the standardization of its components. The regression model is used to determine the length of the keel, the height of the boat, the length of the boat, and the width of the boat. The results show the general arrangement, lines plane design, and facility layout of traditional boats based on the regression model. This study will contribute to the business process development at the shipyard and the small craft technology.
