Minimarkets or supermarkets are one of the places to buy all the basic needs that humans need. The method of payment using tunai is sometimes difficult when the tunai brought is less than the calculation before shopping, in preventing excess purchases or lack of money when shopping it is recommended to calculate the items spent on their own, but the process takes a long time, especially when customers pay for goods shopping at the tunaiier. This research applies system development by applying XAMPP and MySQL for database management and using android studio software based on android. The final result of this research is to apply a QR Code as a walking tunaiier in a mini market. The application used in the application of this QR Code only scans the barcode listed on the item and submits the QR Code to the tunaiier so that it can facilitate the transaction process</em></p> 2021-12-20T00:00:00+00:00 Copyright (c) 2022 Jurnal Ilmiah Informatika dan Komputer WEB APPLICATION FIREWALL UNTUK MENINGKATKAN KEAMANAN INFORMASI 2022-04-24T14:40:36+00:00 Naufalarizqa Ramadha Meisa Putra <p>Due to the increasing spread of the Internet and information systems, thus causing web applications, the risks and associated threats in this field have also increased. In recent years, several different websites such as government sites and non-government sites have been targeted by penetration attacks and illegal hacking activity. The attacks carried out often result in significant financial and credibility losses along with harming organizational and even national interests. Given the magnitude and complexity of cyberattacks and due to the diversity of web application structures, the need to have comprehensive and effective solutions to prevent or mitigate the negative effects of such attacks is very important. One of the latest tools to prevent infiltration and attacks on websites is a web application firewall (WAF), which allows security policies to be enforced between the user and the web application. In this journal, five simulations of cyberattacks have been carried out to determine how effective the use of WAF is in preventing and minimizing the risk of cyberattacks. In conclusion, WAF can block all five simulated attacks instantly.</p> 2022-03-03T00:00:00+00:00 Copyright (c) 2022 Jurnal Ilmiah Informatika dan Komputer RANCANG BANGUN SISTEM ABSENSI DAN BUKA PINTU DENGAN MENGGUNAKAN RADIO FREQUENCY IDENTIFICATION 2022-03-03T15:04:07+00:00 Junaidi Elmi Devia Akbar Fiansah <p><em>The room security system now also has a good security system by entering the employee ID number on the tool provided next to the door when you want to enter the room. But the security system opening the door is still not secure when the employee ID is known by many people. In terms of time efficiency, it is still considered impractical because it uses employee ID numbers and passwords which take a long time to find the right number. Radio frequency identification (RFID) is a technology that uses communication via electromagnetic waves to change data between a terminal and an object such as a product, animal or human product for the purpose of identification and tracking through the use of a device called an RFID tag. In the application of RFID for attendance and unlocking doors, this system makes it easy to monitor and control employees who enter certain rooms that are considered private.</em></p> 2022-03-03T00:00:00+00:00 Copyright (c) 2021 Jurnal Ilmiah Informatika dan Komputer
