Abstract

Mandakini Neo is an autonomous vehicle that was designed and built by the students of the Universitas Sebelas Maret, which was included in the Bengawan Unmanned Vehicle (UV) Roboboat Team to compete in the annual international Roboboat competition of 2021. This competition requires participants to complete several missions; one of the main missions is to move through two gates made from four poles using full automatic navigation, in order to continue on with the other missions. To complete the course, we used Pixhawk and GPS to allow the ship to run automatically, while minimizing the ship’s movement tolerance. The use of Mission Planner software for monitoring, and also for color and shape image processing to help with the reading of objects, along with a sensor fitted on the ship, allowed the mission to be completed. Mandakini Neo was made with the capacity, speed, and comfort of the ship in mind, as well as the ship’s hydrodynamic performance, stability, volume, structural integrity, and construction cost. Following its development we conducted tests of stability, maneuverability, and seakeeping in order to achieve the smallest possible resistance rate; for this purpose, we used the Savitsky method. The manufacture of the ship also required the choosing of the material, the use of the sensor, and also selection of an appropriate system. Finally, the design that we developed was a ship with a catamaran hull type, for which the dimensions had already been calculated, and the proper materials decided, and simple electrical components were able to be obtained for the sensor and the system.

Abstract

The use of fossil fuels is becoming increasingly expensive, and the amount is limited. Utilizing wind and solar energy sources onboard fishing vessels during operation is one of the solutions to reduce operational costs. This article presents a study on applying solar photovoltaic (PV) and wind turbines for a 14-meter BSC (Blue Swimming Crab) fishing vessel in Rembang Regency, Indonesia. This study discusses the use of renewable energy sources that can be applied to meet onboard electricity needs and their economic impact. This analysis considers to operating system scenario for seven days catching the BSC in the Java Sea. The calculation results show that the solar PV and wind turbine energy that can be utilized as electrical energy are 22,960-Watt h. The required battery is 20 units at 100 Ah 12 Volts and an investment cost of USD 21,084. The advantage of applying this technology is an operational cost saving of 16%, which can increase fishermen’s income by 11%. The challenge of a hybrid or electric propulsion system is fantastic, using the serial configuration of the power topology, and the result of preliminary estimates of the investment value is approximately 173,277 USD.
