Abstract

The op amp amplifier is a very important component in electronics education. because, there is nothing more fundamental in teaching electronics than the op-amp (operational amplifier). This research is used to analyze op amp circuits with a focus on their performance characteristics and versatility in various configurations such as inverting, non-inverting, summing inverting, summing non-inverting amplifiers. This practical tool requires several supporting tools such as a power supply as a voltage input and an Oscilloscope as a wave reader, input, and output from the circuit in practice, using a laptop with the livewire application which is used to carry out the simulation first before carrying out the practice and several other supporting tools. The aim of this research is to design and create a practical application for Op-amps (Operational Amplifiers) based on IC TL084 and IC 741. The use of practical modules based on Op-Amp ICs is expected to provide direct experience that is relevant to real applications in the industrial world, such as sensor signal processing, health monitoring devices (EKG and EEG), Audio Amplifiers, Motor controllers, and others.

Abstract

The employment of security features is crucial to the operation of many modern electronic gadgets in the current 5.0 era as time and technology advance. This means that we must keep coming up with new ideas and producing instruments that will enhance security. Among the many issues that come up is the fact that guns are still registered, checked out, and returned using public books, which leaves space for data tampering or the chance that the books are lost. The primary goal of this research is to create and execute a web-based system that uses fingerprints to monitor the borrowing and return of firearms. Because of its nature online-his, this system will streamline operations and enable users to conveniently view inventory from any location. Researchers employ literature methodology, which includes reading, debating, synthesizing, and developing the concepts employed, in addition to employing laboratory techniques and the necessary tools to accomplish their objectives. The web server on which the security monitoring system for keeping firearms is based has undergone extensive testing and analysis, and the findings indicate that generally, the device can operate as intended. This conclusion is based on traffic analysis and access patterns on the web server. Following the completion of five tests with a 95% accuracy rate. Finally, the security monitoring system for the storage of firearms is based on a web server and has undergone extensive testing and analysis with a 90% speed and accuracy rate; the findings indicate that, on the whole, the instrument can perform as intended

Abstract

Industry 4.0 is bringing about a rapid advancement in technology, particularly in the military industry. This robot was designed to reduce danger to TNI members while monitoring military operations more swiftly and safely. The application of IMU sensors for acceleration movements, measurement of control system error values, and trajectory tracking with multiple pathways are the three modes of the robot control system observed in this study. We assess each of these modes using an analytical observational method. In addition to an MPU 6050 ultrasonic and gyro sensor to detect movement using an accelerometer and gyroscope, the robot is equipped with a rotational encoder sensor to link the DC motor rotation. The PID control approach uses inverse kinematics to regulate the DC motor. The exam is administered on a track that has squares, triangles, and circles as obstacles. According to test results, the tachometer's inaccuracy rate in RPM is about 1.2% higher than the rotary encoder. The movement success percentage for the omni-wheel robot is 89.31%. Square trajectories have an average error rate of 11%, circular trajectories of 15%, and triangular trajectories of 4.17%. The motor rotation speed is most stable along the triangle path. Overall, this study demonstrates the accuracy and speed with which a mobile omni-wheel robot equipped with a control system can peek. This could raise military operations' level of efficiency and safety

Abstract

The study of information security methods to prevent unauthorized parties from reading it is known as cryptography. The Caesar Cipher method is a low-tech yet well-established cryptography technique. One of the earliest and most basic cryptographic methods is the Caesar Cipher, which substitutes a different letter with a specific alphabetic difference for each letter in the text. The Caesar Cipher is simple to comprehend and use, but it has a lot of flaws that leave it open to frequency analysis and brute force attacks. The purpose of this study is to use the Google Colab tool to examine the cryptographic security of the Caesar Cipher technique. In this study, Google Colab—a platform that offers a robust and user-friendly Python programming environment—was utilized to construct and evaluate the Caesar Cipher algorithm. This study design combines an experimental strategy with a descriptive method. The Caesar Cipher technique is put into practice, encryption and decryption simulations are run, and character frequency analysis and brute force assaults are used to analyze security flaws. The study's findings demonstrate that the character distribution pattern is preserved when character frequencies in the original and encrypted text are seen, making it simple for attackers to use frequency analysis to crack the password. This suggests that, in the context of high information security, the Caesar Cipher should not be used. Shift passwords are therefore inappropriate for use in contemporary security applications due to their serious flaws

Abstract

Salah satu komponen paling penting dari upaya penyelamatan sandera adalah kesepakatan tentang pembebesan sandera. Kesalahan petugas dalam mengambil tindakan selama proses negosiasi dapat membahayakan keselamatan personel dan petugas serta korban yang disandera. Kurangnya komunikasi sering menyebabkan konflik yang berbahaya yang dapat menghambat penyanderaan. Untuk mengatasi masalah ini, kami merancang robot negosiasi khusus yang dipersenjatai untuk memastikan keselamatan dan keamanan petugas dalam menjalankan tugas, baik dalam situasi perang maupun operasi pembebasan sandera. Dengan memiliki senjata, petugas yang bertanggung jawab atas keselamatan korban dapat melakukan tugas mereka tanpa mengorbankan keamanan pribadi mereka. Robot militer ini memungkinkan negosiasi dan pemantauan tanpa mengancam nyawa, memberikan pendekatan yang lebih efisien dan aman. One of the most important components of hostage rescue efforts is an agreement on hostage release. Mistakes by officers in taking action during the negotiation process can endanger the safety of personnel and officers as well as victims being held hostage. Lack of communication often leads to dangerous conflicts that can hinder hostage taking. To overcome this problem, we designed a special negotiation robot that is armed to ensure the safety and security of officers in carrying out their duties, both in war situations and hostage release operations. By having a weapon, officers responsible for the safety of victims can carry out their duties without compromising their personal safety. These military robots enable negotiation and monitoring without threatening lives, providing a more efficient and safer approach. Additionally, the robot's ability to operate autonomously with the help of artificial intelligence allows for quicker assessment of the situation and more appropriate responses, thereby increasing the chances of success of a rescue mission without increasing risks for the humans involved. The robot is also equipped with advanced sensors and machine learning algorithms that can detect changes in a hostage taker's behavior and body language, providing valuable information to the negotiation team to devise more effective strategies. Thus, the implementation of this technology not only increases the security and efficiency of military operations, but also paves the way for further innovation in the use of robotics and Artificial Intelligence in various aspects of defense and security
