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.

<p>Abstract<br />Javanese script is an ancient manuscript of ancestral cultural heritage in the form of handwriting which stores various expressions of thoughts, feelings, and results of past cultures. The contents of the diary text of the Babad Bagelen manuscript tell about the leading figure of the first Purwareja regent who was formerly known as the Bagelen area, namely Raden Adipati Cakranagara 1. The colonial era was full of pressure and policies that harmed the natives. This leadership attitude is in the manuscript of Babad Bagelen with the study of Social Psychology by David G. Myers. The presentation of the results of this study was carried out by analyzing the leadership attitude of Raden Adipati Cakranagara 1 which includes (1) Caring for others, (2) Reminding others, (3) Serving others, (4) Giving gifts, (5) Distributing good invitation quotes. The above data written in the Babad Bagelen manuscript shows the leadership attitude of Raden Adipati Cakranagara when he became Regent in Purwareja (Bagelen). The attitude studied through the Social Psychology approach is very suitable for revealing the problems written</p><p>Keywords: Babad Bagelen, Raden Adipati Cakranagara 1, Social Psychology, David G.
