Implementasi Algoritma Penjadwalan Multilevel Feedback Queue pada Aplikasi Berbasis Flutter

2023-12-19T09:10:00+00:00

Application development has experienced a shift towards a cross-platform approach, where developers can write code once for multiple platforms. Flutter, as a fast-growing cross-platform framework with a wide community is one of the most popular cross-platform frameworks today. However, along with that, there is an increase in application complexity which makes the concept of multitasking very important. This article proposes the implementation of the Multilevel Feedback Queue (MLQ) scheduling algorithm in Flutter applications, which can help manage tasks and improve application efficiency. This research aims to examine the changes in application efficiency after the implementation of MLQ, as well as examine whether the changes remain relevant on different operating systems, namely Windows and Android. The implemented MLQ algorithm is an algorithm with adjustments to the calculation of time quantum and integration with the Shortest Job First (SJF) algorithm based on previous research. Tests were conducted using the Flutter benchmarking feature to measure the application frame rate before and after MLQ implementation on Windows and Android. The results of this study found that the implementation of MLQ increased application efficiency by 269% on the Windows operating system and 155% on the Android operating system.

Perancangan Sistem Smart Door Dengan Notifikasi Telegram

2023-12-20T03:46:58+00:00

With the development of IoT, security systems can now be accessed and tracked with a smartphone. One of the security system that can be used is RFID. RFID uses radio waves to read data from a microchip as identity. RFID systems work on electronic principles so they are more difficult to open than key systems. The key system is universal type so with one key can open the same door lock system. To prevent the possibility of keys being duplicated, a security system is needed that is more difficult to open and sends notifications to the owner if an attempt is made to access the door. By utilizing the RFID system and using telegram as a notification system, an RFID security system was designed which was equipped with a telegram notification system.

The ability of a database to store significant amounts of data must be balanced with the speed with which users can access the information they need so that technological developments can keep up with the changing needs of users. In today's fast-paced and sophisticated world, an information technology service must be able to respond to data requests and process data quickly and effectively. However, when processing data, a system that stores too much data will inevitably encounter time constraints. By creating a web-based seed application information system, it can assist agencies in inputting community data, it can also assist organizations in online seed marketing using the Flask Framework. The results of the study show that this system makes it easy to view and record data, making it easier for officers at BPDAS Pemali Jratun to improve service to the community.

2023-12-24T03:49:19+00:00

In the rapidly evolving digital era, human communication has undergone significant changes thanks to instant messaging. Instant messaging enables us to easily and quickly connect with people around the world through mobile devices or computers. However, the use of instant messaging applications can have negative impacts such as fraud, harassment, illegal transactions, and more. Therefore, proper handling of cybercrime cases is crucial, which is why mobile forensics has become significant. Mobile forensics is a branch of digital forensics that aims to collect, analyze, and interpret data from mobile devices. This research aims to evaluate the performance of three forensic tools: Oxygen Forensic Suite, Belkasoft Evidence Center, and MOBILedit Forensic Express. It focuses on finding digital evidence related to activity information in the Skype application using the framework provided by NIST. The research results indicate that Oxygen Forensic Suite achieved the highest index value (98%), followed by Belkasoft Evidence Center (88%) and MOBILedit Forensic Express (84%).
