Abstract

The E-Attendance System has become an efficient solution in monitoring individual attendance at various institutions. However, new challenges arise regarding data security and privacy in managing E-Attendance database files. Facing potential risks such as hacking and data leaks, data security becomes very important. Therefore, in this study, we propose the implementation of a hybrid system that combines the strengths of the Rivest Shamir Adleman (RSA) Algorithm and the Blum Blum Shub (BBS) Algorithm to improve the security of the E-Absence database file. RSA is a cryptographic algorithm that is widely used for encryption and digital signatures. On the other hand, BBS is a random number generation algorithm that has a strong level of security. The combination of the two in the form of a hybrid system is expected to provide a higher level of security in securing E-Absence data. The aim of this research is to develop a hybrid RSA and BBS system in the context of securing E-Attendance database files. This research outlines the basic concepts of the two algorithms and how they can be integrated. The results of this study are the combination of the Rivers, Shamir, Adleman (RSA) algorithm and the Blum Blum Shub (BBS) algorithm in a hybrid system to increase security in the process of encoding messages

Abstract

This research discusses the design and implementation of a robot arm that is controlled via smartphone using the Internet of Things (IoT) concept. This robotic arm is controlled using a microcontroller connected to the internet. The aim of this research is to develop a system that allows users to easily control the movement of the robot arm via a specially designed smartphone application. At the design stage, the microcontroller is programmed to control the motors that drive the robotic arm joints. Communication between the smartphone and the robot arm is implemented via a network communication protocol, so the user can give commands via an intuitive application interface. The use of IoT technology allows this robot arm to be controlled remotely via the internet, opening opportunities for use in various contexts, such as use in production, education or even entertainment environments. Test results show that the robotic arm can automatically carry out repetitive tasks with a high level of accuracy. This advantage can increase productivity in the production process and reduce the potential for human error. In addition, robots can operate in environments that are potentially dangerous to humans, such as toxic, radioactive or extreme temperature (hot or cold) areas. This capability effectively reduces the risk of human exposure to these potential hazards

Abstract

The development of information technology demands the need for effective network security design to protect communications infrastructure, especially routers, from brute force attacks. Brute force attacks are a method commonly used by attackers to try password combinations repeatedly until they successfully enter the system. This research aims to design a network security solution that can prevent routers from being exposed to brute force attacks. This research combines technical and conceptual approaches to identify potential vulnerabilities in routers and develop security strategies that can overcome these challenges. Security methods include implementing strong password policies, real-time attack detection, and improving response to suspicious access attempts. By implementing this security solution, it is hoped that it can increase the level of network security, reduce the risk of brute force attacks, and protect data and services that pass through routers. The results of research using Mikrotik RouterOs show that RouterOs is able to defend against bruteforce attacks. The attack that was attempted was successfully blocked by RouterOs
