Software contains electronic data stored in computer devices. Measurement is the foundation of every engineering discipline and applies to software engineering as well. To evaluate the performance of a system or process, a mechanism is needed to observe and determine the level of efficiency. In software measurement there is an application to measure the value of the software. There are several methods of measuring software, one of which is the function point. Function point is one method that can measure software. This method produces the points needed to assess how much the price of a software is. The points are divided into two categories, namely Crude Function Point (CFP) and Relative Complexity Adjustment Factor RCAF. By using these points, a fixed price can be determined for a software.</span></p> Rizky Parlika, Rayhan Rizal Mahendra, Muhammad Rafli Aulia Rojani Lutfi, Rizqy Khoirul Waritsin, Humam Maulana Tsubasanofa Ramadhan Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/5578 Fri, 10 Mar 2023 00:00:00 +0000 PENERAPAN HFSM PADA GAME 3D “PETUALANG QUR’AN” https://ejournal.upbatam.ac.id/index.php/jif/article/view/6538 <p>Game is a game that is very liked by children and adults.

Ethical hacking and its need in the future cannot be avoided. Ethical hacking technology is spreading in almost every aspect of life, especially the computer industry, which requires protection of important data and must be handled with the right technology. Ethical hacking aims to find vulnerabilities in security systems and discover potential data breaches. This contrasts with the common understanding of hacking, which is black hat hackers who damage systems with malicious intent and steal data and infect viruses. Ethical hacking is a way to combat and neutralize black hat hackers. Teaching ethical hacking is preparing professionals in the information security field with the tools and skills to combat and prevent cybersecurity threats. Teaching inexperienced people in information security with aggressive methods can be viewed as both beneficial and harmful. This is because the same methods are used by malicious hackers hence educating professionals in information security may be perceived as enhancing malicious hackers. Using the literature study method, this article discusses various issues related to ethical hacking.</p> Qorry Aina Fitroh, Bambang Sugiantoro Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/6593 Fri, 10 Mar 2023 00:00:00 +0000 ANALISIS SENTIMEN ULASAN APLIKASI POSPAY DENGAN ALGORITMA SUPPORT VECTOR MACHINE https://ejournal.upbatam.ac.id/index.php/jif/article/view/6611 <p><em>Pospay application is a form of financial technology belonging to Pos Indonesia. Pospay application on the Google Play Store has more than 25 thousand user reviews. The more user reviews, the more difficult and longer it will take for prospective users and application managers to conclude information on user sentiment trends that are useful in making decisions about application use and evaluation. Sentiment analysis is the solution to this problem because sentiment analysis is able to classify unstructured data to generate sentiment information efficiently by applying data mining algorithms. This research uses the Knowledge Discovery in Database (KDD) method, where at the data mining stage, the Support Vector Machine algorithm is applied in making the model. Grid search was applied to test 3 scenarios so that the proportion of data distribution with the best accuracy was obtained, namely, 90:10, using RBF kernel with parameters: c = 1, ℽ = 1. The results of this research were a model with 95% accuracy, 91% precision, 100% recall, and 95% f1-score. Information was also obtained that the sentiment of Pospay application users on the Google Play Store tends to be positive (54.1%) but not much far from the percentage of negative sentiments (45.9%).</em></p> Dea Safryda Putri, Taufik Ridwan Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/6611 Fri, 10 Mar 2023 00:00:00 +0000 SISTEM INFORMASI UNIT KEGIATAN MAHASISWA DAN HIMPUNAN MAHASISWA JURUSAN POLITEKNIK NEGERI FAKFAK https://ejournal.upbatam.ac.id/index.php/jif/article/view/6715 <p>Today's information systems are inseparable because they demand a company to create an integrated system that allows others to access the information they need from the company. The Student Activity Unit or UKM organization and the Departmental Student Association (HMJ) are two that are affected, making it simpler for students to obtain information, which is one of the most crucial requirements that must be met. Numerous student organizations are supervised by the Fakfak State Polytechnic and are grouped under the Student Activity Unit (UKM). Student activity units and major student associations at the Fakfak State Polytechnic currently do not have an integrated information system that explains management profiles, vision and mission, and work programs. This has an impact on the lack of information obtained by students and the public regarding UKM and HMJ at the Fakfak State Polytechnic. Therefore, efforts are needed to build and improve an information exchange system in the form of a website-based application for student activity units and departmental student associations that can manage information from each organization in an integrated manner to be able to overcome these problems. The information system that will be built and developed is a web-based application that makes it easier for users to access information and also acts as a promotional medium.</p> Ardhyansyah Mualo, Hasan Basri, La Ode Syaiful Djamani Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/6715 Fri, 10 Mar 2023 00:00:00 +0000 RANCANG BANGUN SISTEM KONTROL MOTOR LISTRIK BERBASIS RASPBERRY PI https://ejournal.upbatam.ac.id/index.php/jif/article/view/6989 <p>This study will develop and execute control of DC motors and servo motors on a 4WD robot controlled by a keypad and equipped with grippers and a USB webcam to broadcast video so that the gripper robot vehicle can view items in front of it.

In Indonesia in 2020 there were more than 3000 positive cases of COVID-19 with a mortality rate of 9.1%. The government's incomplete efforts to break the chain of the spread of COVID-19 have made people uneasy about this pandemic. Many people want to express their aspirations on social media which is considered suitable as a place that represents the aspirations of the COVID-19 pandemic. One of them is twitter. There are so many text messages sent, some positive and some negative, that it is difficult to retrieve harmonized information due to the diversity of text messages sent. One way to overcome this is with sentiment analysis. This research has processes including text preprocessing, word weighting, classification with K-Nearest Neighbors (KNN) and Naïve Bayes Classifiers (NBC) algorithms. The results obtained by KNN got an accuracy of 72.37% while NBC amounted to 67.84%. KNN is the best classification algorithm for negative sentiment classification, the negative label predicted correctly in KNN is greater, namely 393 compared to NBC which is 339. while NBC is the best algorithm for positive sentiment classification, the positive label predicted correctly NBC is 275 greater than KNN as much as 262.</p> Habibi Aulia Nur Syifa Habibi, Arie Nugroho, Rina Firliana Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7069 Fri, 10 Mar 2023 00:00:00 +0000 IMPLEMENTASI AUGMENTED REALITY BERBASIS FILTER INSTAGRAM PADA PENERAPAN MEDIA PEMBELAJARAN TENTANG PENGENALAN TATA SURYA https://ejournal.upbatam.ac.id/index.php/jif/article/view/7155 <p>The need for interactive media in learning is starting to be in demand by the wider community and along with the increasing use of Smartphones in times like this Augmented Reality (AR) is a new medium in the learning process of children's Natural Sciences in recognizing the planets in the Solar System and can handle problems from traditional learning media that exist today which are felt to be less informative and interactive for children, from the function of using educational media that can visualize various objects and information that can arouse curiosity in students so that children can start to be more active in learning.

However, with all the facilities available, the use of information technology is still a little applied in local communities. The learning documentation process at TPQ Aisyah Maulidah Hasanah still uses the conventional method, where students and parents of students can only see learning outcomes through paper media. The recording of monthly contribution payments also still uses a notebook which has the potential to lose data if a lost book is replaced or a book is lost. Information technology can be used to help TPQ Aisyah Maulidah Hasanah and parents of students so that data recording is safer through a website-based information system which is expected to facilitate the processing and receipt of information by TPQ managers and parents of students regarding recording the development of student achievements and payment of dues. Using the waterfall method and the Laravel framework, this website-based information system is expected to streamline the process of recording information related to the development of students' achievements and to minimize the potential for data loss</p> Afif Amirudin, Muhamad Azrino Gustalika Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7159 Fri, 10 Mar 2023 00:00:00 +0000 ANALISIS SERANGAN DHCP STARVATION ATTACK PADA ROUTER OS MIKROTIK https://ejournal.upbatam.ac.id/index.php/jif/article/view/7162 <p>Dynamic Host Configuration Protocol (DHCP) is a client-server protocol that functions to provide IP addresses to client computers/network devices automatically.

Domain registration is the first step in website development as an effort to the existence of a business entering the digital economy era. To ensure the continuity of a business in the internet world, the selection of a domain registration service is very important. Because the domain is the identity as well as the address of a business on the internet. Domain registration service organizations must meet various important criteria needed as a professional domain registration service. These criteria must be able to answer the crucial characteristics of a domain registrar. This study uses PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation). The PROMETHEE method is used to rank among all alternatives based on predetermined criteria. The stages of problem solving in this study are determining alternatives, determining criteria, to ranking alternatives, so that will produce the best alternative output. In this study the PROMETHEE calculation results obtained with the best alternative output being the Domainesia registrar with a net flow value of 0.592.</p> Maha'd Wicaksono, Maulana Ighsan Lucky Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7174 Fri, 10 Mar 2023 00:00:00 +0000 SISTEM INFORMASI KETERSEDIAAN DAN PERKEMBANGAN HARGA BAHAN POKOK SECARA REAL TIME BERBASIS WEB https://ejournal.upbatam.ac.id/index.php/jif/article/view/7168 <p>The Office of Industry, Trade, Cooperatives, Small and Medium Enterprises of Pidie Regency has not yet used a media website that can provide information on the availability and price developments of basic commodities. Data on the development of prices for basic goods is very important for the agency overseeing the trade sector. This is also very useful for identifying the causes of price fluctuations or fluctuations in an effort to maintain the stability of price developments. So we need a system that records information on the availability and price developments of staple goods in real time, the design of this system uses the PHP programming language and MySQL Server Database which allows it to be accessed anywhere and anytime. The benefit to be gained from this system is that it makes it easier for the Office of Industry, Trade, Cooperatives, Small and Medium Enterprises of the Pidie Regency to convey information on prices of basic goods to the public quickly and accurately</p> Rahmat Sufri, Mukhroji Mukhroji, Nazuarsyah Nazuarsyah, Rossiana Br Ginting, Satria Prayudi Copyright (c) 2023 JURNAL ILMIAH INFORMATIKA http://creativecommons.org/licenses/by/4.0 https://ejournal.upbatam.ac.id/index.php/jif/article/view/7168 Fri, 10 Mar 2023 00:00:00 +0000
