This problem can be solved by utilizing ICT, which is to create a payroll information system according to class or position and the deductions evenly. The method used to design this payroll information system is the waterfall method, with Unified Modeling Language (UML), Macromedia Dreamweaver CS 6 for interface design and XAMPP for database design. The purpose of this research is to be able to process all employee salary data at the Sorong Kepulauan District office in detail so that it is effective and efficient in order to produce an information system that is fast, precise, and accurate.</p> 2022-04-30T00:00:00+00:00 Copyright (c) 2022 Matheus Supriyanto Rumetna, Tirsa Ninia Lina, Iriene Surya Rajagukguk, Frenny Silvia Pormes, Agustinus Budi Santoso http://ijadis.org/index.php/IJADIS/article/view/1231 Security System Analysis against Flood Attacks Using TCP, UDP, and ICMP Protocols on Mikrotik Routers 2022-06-03T21:55:11+00:00 Warid Yunus warid.dsn@gmail.com Mohamad Efendi Lasulika fendidsn.ui@gmail.com <p>Advances in information technology today require all existing computer networks to be able to show that the security system model continues to be considered very important for users who want security both from inside and outside the network. An attack on a network server can occur at any time, as for an attack that can cause a dangerous effect on a router, namely DDOS / flood by flooding the router with very many data packets so that the router can be paralyzed in terms of handling the network system. In this study, descriptive research was applied to obtain data directly by conducting flooding techniques and analyzing and designing flooding prevention techniques with filtering techniques. The application of filtering on the firewall on MikroTik can minimize attacks and prevention directly by dropping flooding packets automatically so that MikroTik performance remains stable</p> 2022-04-30T00:00:00+00:00 Copyright (c) 2022 Warid Yunus, Mohamad Efendi Lasulika http://ijadis.org/index.php/IJADIS/article/view/1232 Network Reconfiguration of 20 kV Sample Connection Substance LG-04 Lhokseumawe City Using Digsilent Power Factory Software Simulation 15.1 2022-06-04T02:01:10+00:00 Arnawan Hasibuan arnawan@unimal.ac.id Kartika Kartika Sahal Mahfudz Muhammad Daud <p>In this final project, we describe the study of reconfiguring the distribution network at the LG-04 feeder at the Lancang Garam substation, Lhokseumawe, to improve the performance of the distribution system. The focus of the parameters considered includes continuity, voltage, and power loss. The reconfiguration is to change the initial network topology which is in the form of radial into a loop. After reconfiguration, the calculation of power flow, voltage drop, power loss, and short circuit calculation is also carried out which becomes a reference for whether or not the quality of the network is good. The results of the simulation of the existing conditions show that continuity is not good, after reconfiguration and fault testing, the network does not experience blackouts like the network before reconfiguration. The power loss generated in the network after reconfiguration is 0.507 kW or a decrease of ±84% from the previous form of the network.</p> 2022-04-30T00:00:00+00:00 Copyright (c) 2022 Arnawan Hasibuan, Kartika, Sahal Mahfudz, Muhammad Daud http://ijadis.org/index.php/IJADIS/article/view/1233 Sentiment Analysis of Kampus Mengajar 2 Toward the Implementation of Merdeka Belajar Kampus Merdeka Using Naïve Bayes and Euclidean Distence Methods 2022-06-10T06:44:59+00:00 Abdul Rozaq kelik@unipma.ac.id Yessi Yunitasari Kelik Sussolaikah vikaelisabeth@gmail.com Eka Resty Novieta Sari <p>The Ministry of Education and Culture initiated the <em>Merdeka Belajar Kampus Merdeka</em> (MBKM) program. Several programs in <em>Merdeka Belajar Kampus Merdeka </em>(MBKM) Program include industrial internships, independent projects, student exchanges, community service projects, humanitarian programs, and so on. <em>Kampus Mengajar</em> 2 is one of the programs had been running. The program received various responses from the public, which were expressed on social media. The Supervisor at <em>kampus mengajar</em> 2 was also active in providing various comments on <em>kampus mengajar</em> 2 telegram groups in the form of good, bad, and neutral comments. These comments have the potential to generate a growing sentiment among the general public and academics. Based on these issues, the researcher analyzed the kampus mengajar 2 sentiments toward the implementation of <em>Merdeka Belajar Kampus Merdeka</em> program with the data source being comments on the supervisors' telegram group. The data obtained from the telegram group is classified as good, bad, or neutral using the Naive Bayes method and K-Nearest Neighbors on up to 591 data points. The data is then divided into two parts: training data and testing data. Testing data can account for up to 20 percent of total data, with the remaining 80 percent serving as training data. The accuracy results on sentiment analysis show that the Naive Bayes method outperforms the KNN method, with 99.30 percent for Naive Bayes and 97.20 percent for K-Nearest Neighbors.</p> 2022-04-30T00:00:00+00:00 Copyright (c) 2022 Abdul Rozaq, Yessi Yunitasari, Kelik Sussolaikah, Eka Resty Novieta Sari http://ijadis.org/index.php/IJADIS/article/view/1234 Heuristic Analysis of the Indonesian Covid-19 Official Website Interface 2022-06-16T05:45:19+00:00 Moch Yusuf Asyhari yusuf.asyhari@unipma.ac.id Kelik Sussolaikah vikaelisabeth@gmail.com Eka Resty Novieta Sari Sekreningsih Nita <p>The Government of Indonesia's official Covid-19 website is the most trusted information link between relevant agencies and the wider community. Usability is an important factor in determining how easily and successfully users can obtain information from a website. Heuristic studies were conducted to obtain findings on the discrepancies in the previously released website design. The website's homepage has a usability percentage of 78.74 percent and a standard deviation of 8.84 percent. The Covid-19 distribution page is 70.36 percent usable, with a standard deviation of 9.84 percent. The evaluation results are based on the United States' Research-Based Web Design and Usability Guidelines. The Department of Health and Human Services (HHS) discovered that the home page's links were poorly identified, that important information was not relevant, and that the use of icons was inconsistent. The distribution page discovered difficult-to-identify links, scrollbar redundancy in the frameset, and content complexity that required the user to be able to read diagrams well.</p> 2022-04-30T00:00:00+00:00 Copyright (c) 2022 Moch Yusuf Asyhari, Kelik Sussolaikah, Eka Resty Novieta Sari, Sekreningsih Nita
