Abstract

The Covid-19 health protocol is a regulation by government to feel safer doing activities during Covid-19 pandemic. Generally, spread of Covid-19 occurs in public places, one of which is a shop. By building an IoT tool that is expected to be able to detect early on the potential for someone to contract Covid-19 by detecting body temperature and mask when entering a store. Shop owners can see people who have the potential for Covid-19 and customers who are wrong/not wearing masks, using IoT functions to send data between sensors so that shop owners can monitor website-based systems. From the test results, the success rate of tools and algorithms is 78.38% of data that successfully detects temperature and masks, then there are 29.62% of data that fail to detect masks and temperatures. The data is then recorded in a JSON file which will be displayed into a website-based information system.

Abstract

The presence of service-oriented computing, through the Service Oriented Architecture (SOA), and the implementation of information technology through website applications provide opportunities for more appropriate system utilization for an organization by providing options for implementing functionalities in a modular manner, according to the needs of the organization following the evolution of service growth, without the need for large Information Technology infrastructure investments. In order to develop an Coaching Information System for Pondok Pesantren Alam Sayang Ibu (PAMSI) with a service functionality basis, it is necessary to define a prototype model of Coaching Information System with an SOA approach through understanding the process of coaching activities and must be relevant to the needs of each party involved. This study aims to create a SOA implementation design that can be used as a guideline to be used as the main foundation in the creation of a PAMSI Coaching Information System and can be used as a reference for the development of other Information Systems at PAMSI.

Abstract

Learning media is an important factor in the learning process. By using the right learning media, someone can easily understand what is being studied. Currently, augmented reality is a technology that is being developed in various fields, one of which is in the field of education. Augmented reality can be an alternative to effective and interactive learning media because augmented reality can combine 2D or 3D objects into a real environment. To learn about the internet of things devices, currently, students can only learn through books or do the hands-on practice. If an error occurs during practice, it can cause damage to the internet of things device. By utilizing augmented reality technology, a new learning media is created by combining 3D objects from internet of things devices into the real environment. This learning media application was tested using the Blackbox and Mean Opinion Score methods. Blackbox testing shows that all functions have been running properly by the functional requirements that have been defined. Testing using the Mean Opinion Score shows that the average student respondent's assessment of the application is stated to strongly agree as much as 60.3% and agree as much as 35.3%.

Abstract

Porang is a plant that has the potential to be developed as an export commodity as a food ingredient or industrial ingredient (i.e., food, cosmetics, medicine, or health). North lombok regency location is one of the districts in ntb that currently has potential for developing porang farming businesses. Porang farming is currently carried out in 2 subdistricts, namely gangga and bayan, and has 800 farmer members with a land area of 1000 ha. Having an android-based application will help with the management of farmer administration. Based on the results of black-box testing, all features were confirmed to function properly. Additionally, the System Usability Scale (SUS) evaluation involving 30 users yielded an average score of 74.16, placing it within the acceptable category).

Abstract

Information technology advancement has significantly impacted Indonesia's education sector, including the University of Mataram. The university relies on the Sistem Informasi Akademik (SIA) for various academic activities. However, increasing users has led to challenges such as excessive traffic and server downtime. This research analyzes the impact of DDoS attacks on the SIA server's performance and utilizes Zabbix for server monitoring. The results show that DDoS attacks mainly burden the network traffic component, with a significant increase compared to normal conditions. CPU and RAM resources also increased but less significantly. Monitoring with Zabbix improves the efficiency of performance management, enabling real-time monitoring and easy-to-understand visualization. The findings help administrators identify the need to increase server capacity and implement DDoS detection and mitigation systems to maintain the quality and availability of academic services.

Abstract

This study investigates security vulnerabilities in secondary school PPDB websites, focusing on Structured Query Language (SQL) Injection and Cross Site Scripting (XSS) techniques. The research aims to conduct a security audit and analysis using XSS methods and Insecure Direct Object References (IDOR) penetration tests. The primary objectives are to identify existing security gaps, provide recommendations for improvement, and enhance the overall security of these websites. By addressing these vulnerabilities, the study seeks to make PPDB websites more secure and reliable in protecting users' personal data and maintaining system integrity. Additionally, this research aims to raise awareness among PPDB system managers and schools about the importance of cybersecurity in website development and management, offering practical solutions and serving as a reference for improving website security in the educational sector.
