THE DESIGN AND BUILD CONTROL SYSTEM AND FIRING TEST ON RBU 6000 WEAPON IN KRI PARCHIM CLASS TO SUPPORT COMBAT AND OPERATIONAL READINESS

Abstract

Parchim class is a warship made in East Germany that entered Indonesia in 1996 and is equipped with AKS (Anti
Submarine) RBU 6000 weaponry. To maintain the reliability of these weapons, the Navy needs to ensure the RBU
6000 firing system is in combat ready condition. However, a number of technical problems still occur in the RBU
fire control and monitoring system, such as limited firing test equipment, long test duration, use of simple
measuring instruments, and unreliability of the firing button. This research aims to improve the RBU 6000 fire
control and monitoring system using INA226 voltage sensors and Teensy 4.0 microcontrollers. The INA226 sensor
has a wide reading range and good compatibility with the Teensy 4.0 microcontroller. This combination allows
high-accuracy reading of the trigger voltage, which allows effective monitoring and analysis of firing. In addition,
the Omron V-15-1C25 limit switch sensor is used as a misfire detector, which is able to distinguish launcher status
and detect changes when the rocket enters and exits the launcher. In this study, software was also developed
using the Windows-based Abacus Delphi7 application, which can control firing, read trigger voltage output, and
monitor the status of limit switch sensors. The software is also capable of carrying out firing tests with a faster
duration, firing in various modes, and moving the training angle and elevation of the RBU tower. The results of this
study show that the use of INA226 voltage sensor and Teensy 4.0 microcontroller effectively improves the RBU
6000 fire control and monitoring system on KRI Type Parchim. The high trigger voltage reading accuracy and
misfire detection capabilities of the Omron V-15-1C25 limit switch sensor provide significant improvements in firing
reliability and safety. With the software developed, the operation of the RBU 6000 has also become more efficient
and flexible. This research is expected to contribute to improving the Navy's defense capabilities in facing
submarine threats.
