The objectives are to promote exchange of information and knowledge in research work, new inventions/developments of Computer Science and on the use of Information Technology towards the structuring of an information-rich society and to assist the academic staff from local and foreign universities, business and industrial sectors, government departments and academic institutions on publishing research results and studies in Computer Science and Information Technology through a scholarly publication.&nbsp;</p> en-US Jurnal Teknik Informatika dan Komputer 2829-0208 Perancangan Sistem Pakar Gejala Penyakit Pada Burung dan Kucing Menggunakan Metode Forward Chaining Berbasis Android https://journal.uhamka.ac.id/index.php/jutikom/article/view/10013 <p><em>This study discusses the problems experienced by pet owners, especially cats and birds in dealing with diseases experienced by their pets. Based on the results of the questionnaires that have been conducted, as many as 74.3% of pet owners have minimal knowledge about what types of diseases can attack their pets (cats and birds), 80% of the distance traveled to the vet clinic is quite far, 60% of the existing veterinarians are still relatively minimal, and pet owners have their own busy lives and activities. This study aims to create an expert system in the form of an android-based application, which can assist pet owners in obtaining information about the results of disease symptoms in pets, what kind of treatment can be given, drug suggestions for the disease. The method for tracing the solution used is the Forward Chainig method, where the analysis is carried out after the information is given to then produce conclusions in the form of the name of the disease. The kar system application is made using the Java and PHP programming languages. The expert system application created in this study can help pet owners, especially cats and birds, in getting information about the symptoms of diseases that attack their pets. This is based on the results of testing the beta test results of all the features in the application running well and a success rate of 100%, and based on the results</em> <em>of the effectiveness test of the acceptance of this expert system application, it is very good at 89.35%.</em></p> Rahmi Imanda Damar Kharisma Fauziyyah Copyright (c) 2022 Jurnal Teknik Informatika dan Komputer 2022-11-27 2022-11-27 1 2 34 40 Penerapan Tools Fail2Ban Untuk Mencegah Serangan Brute Force Pada Web Server Online Learning Uhamka (OLU) https://journal.uhamka.ac.id/index.php/jutikom/article/view/10447 <p>This study aims to assist the internal team of BPTI UHAMKA in making the Online Learning UHAMKA (OLU) web server so that the login credentials of the UHAMKA academic community are protected from attempted brute force attacks. Fail2Ban is a server security tool where it detects login attempts according to the maximum pre-configured trial value. In its implementation, Fail2Ban which uses the python programming language is installed on the Online Learning UHAMKA (OLU) server that uses the CentOS 7 server operating system. In the way it works, Fail2Ban will block or ban IP addresses that try to log in consecutively within one hour. Based on the comparison before and before its implementation, it can be proven that Fail2Ban can detect brute force attacks that occur and ban the attacker's IP address.</p> Yustika Ramadhani Muchammad Sholeh Copyright (c) 2022 Jurnal Teknik Informatika dan Komputer 2022-11-27 2022-11-27 1 2 41 45
