Abstract

Currently most of the marine fishing in Indonesia uses traditional boats with navigation systems using compasses and mobile phones. Besides being ineffective, this fishing system also has a high risk, so a safer fishing system is needed, namely using an autonomous boat with a system capable of attracting fish. The use of the Autonomous Surface Vehicle (ASV) for monitoring and fishing purposes has been carried out by Aryusmal (2018) [1] , namely using GPS equipped with an Arduino Uno microcontroller to carry out ship movements, and an error of 1.5 m was obtained. Whereas Permana (2018) [2] made an ASV ship with GPS equipped with an APM microcontroller and Arduino Uno, an error of 30 cm was obtained. Referring to the need for a safe fish system and the results of previous research, this paper designed an autonomous ship with a GPS navigation system using a pixhawk microcontroller which is supported by the use of a brushless motor as the main propulsion of the ship and mission planner software to determine navigation waypoints. This system is able to monitor in real time and save the results of navigation and compass movements up to the last waypoint on the Pixhawk microcontroller. To find out the performance of the ASV, waypoint latitude and longitude tests were carried out on a laboratory and field scale. Laboratory test results have an error of 1.7%, while the results of field testing error errors that occur are 4.4% at longitude and the smallest error is 1.3% at latitude. This error occurred due to field conditions due to sea water shocks. However, this error did not really affect the movement of the ASV ship, because the shift was not too far.

Abstract

Upright is part of the car's suspension system that plays an important role in creating and comforting the car. Supporting driving safety, upright components must be designed to be light but strong to withstand loading when the car is in conditions of acceleration, deceleration and cornering. Not only strong as a benchmark, but components must also be lightweight, so we need a method, namely a topology optimization method. Using finite element software makes the optimization process very easy and very fast with maximum accuracy. The process is by inputting the model from CAD software, defining materials, input constraints and vector styles, meshing process, and finally the solution process. From the simulation results, it will be known the value of the solution in the form of stress, deformation and safety factor of the upright component. From several topology optimization designs, they will be compared to find out which is the best design which will be used as a design recommendation. By referring the result, 43% mass reduction is the best optimum design, its safety factor is 4.956.
