Mon, 01 Apr 2024 10:52:04 +0700

Internet is a very important need in the life of people in the world. Universities can exchange information and share data and communicate with the internet network. General Achmad Yani University Yogyakarta (Unjaya) uses the internet network for activities that occur on campus. QoS testing or internet network performance aims to maintain the stability of network access on the Unjaya campus and reduce the risk of problems such as delays in data transmission. In addition, this research also aims to determine the results of signal quality measurements in the Unjaya real-time area. In this research, QoS measurement is done by using wireshark application. The QoS parameters measured are throughput, delay, jitter, and packet loss. Based on the measurements taken, the results obtained for QOS measurements show that WiFi network performance based on throughput, delay, jitter, and packet loss parameters is in the good category. The final result obtained after measuring QoS is that the Internet network at Campus 1 Unjaya is in the medium category based on TIPHON standardization with an index value of 3.

Kajian Keamanan Sistem Informasi Akademik Menggunakan Framework COBIT 5

Yonal Supit, Edy Irwansyah — Mon, 01 Apr 2024 10:52:39 +0700

This study examines the security of academic information systems using the COBIT 5 Framework. Key issues are uncertainty in protecting student and staff data, the potential for cyberattack vulnerabilities, and non-compliance with international security standards. The goal is to evaluate the security level of the system and suggest improvement recommendations according to COBIT 5 principles. Research methods include Renstar IT policy analysis, system audits, and interviews with IT personnel and related academic communities. Data is analyzed quantitatively to identify weaknesses and opportunities for improvement. The COBIT 5 framework is used as a security assessment framework. The results highlight the need for improvement, including access management, activity monitoring, and continuous improvement plans. Using COBIT 5, substantial measures such as strengthening access controls and developing disaster recovery plans can be identified. The research emphasizes the importance of a structured approach in improving the security of academic information systems, with COBIT 5 as a useful tool. With the right measures, system security can be enhanced to protect the integrity, confidentiality, and availability of critical data for educational institutions. In conclusion, these measures demonstrate how important COBIT 5 implementation is in addressing information security challenges in academic environments.

Expert systems can assist an expert in making decisions that are realized in the form of a program. At this time the program is very helpful in improving various fields such as health, by managing the information that has been obtained. In this research, rhinitis is raised as a topic of discussion by working with experts who are experts in the field, after collecting data through interviews, the conclusion is obtained, namely how to determine whether someone has one of the three types of rhinitis (allergic rhinitis, bacterial rhinitis, and viral rhinitis) with the symptoms experienced and with a fast and accurate process. By using the certainty factor method and applying it to a web-based expert system, it makes it easier for patients and experts to solve the problem, there are 31 types of symptoms among the three types of rhinitis diseases that are used as the basis for the expert system after that with data from 20 patients at the hospital who suffer from various symptoms of rhinitis who have been diagnosed with the disease by experts as validation data and trials it is found that the system is 100% successful in accurately diagnosing each disease in all these patients.

Analisis Aspek Filsafat Sains pada Bidang Graph Mining dan Kemiripan Aturan Hukum

Amany Akhyar — Fri, 17 May 2024 00:00:00 +0700

Hukum di Indonesia berjumlah sangat banyak dan saling berhubungan atau merujuk antara satu sama lain. Salah satu fenomena hukum yang ada di Indonesia yaitu terdapat kemiripan aturan hukum sehingga menimbulkan masalah yaitu aturan hukum yang tumpang tindih dan tidak sinkron. Ketika aturan hukum yang baru akan dibentuk, sebaiknya tersedia tools yang dapat melakukan pemeriksaan terlebih dulu terhadap hukum lama sehingga tidak tumpang tindih dan sinkron. Knowledge graph (KG) digunakan pada penelitian ini untuk merepresentasikan hukum-hukum yang ada di Indonesia. Penelusuran KG tersebut akan dibantu dengan teknologi graph mining. Pada penelitian ini, dibahas pula aspek-aspek filsafat sains pada beberapa penelitian terdahulu yang berkaitan dengan topik penelitian ini.

Analisis User Experience pada Aplikasi Mobile SIA Universitas Teknologi Yogyakarta Dengan Metode User Experience Questionnaire

Mon, 27 May 2024 11:54:47 +0700

Metode User Experience Questionnaire (UEQ) digunakan dalam penelitian ini untuk mengevaluasi User Experience (UX) pada aplikasi mobile Sistem Informasi Akademik (SIA) di Universitas Teknologi Yogyakarta. Seiring dengan pesatnya kemajuan teknologi informasi di Indonesia, lembaga pendidikan semakin banyak menggunakan teknologi untuk meningkatkan efisiensi dan kemudahan akses ke informasi. Fokus penelitian ini adalah untuk mengevaluasi kualitas pengalaman pengguna melalui enam skala UEQ: Attractiveness (Daya Tarik), Perspicuity (Kejelasan), Efficiency (Efisiensi), Dependability (Ketepatan), Stimulation (Stimulasi), dan Novelty (Kebaruan). Penelitian ini bertujuan untuk meningkatkan kepuasan pengguna dan meningkatkan kualitas melalui pengembangan aplikasi mobile SIA UTY. Harapan kami adalah temuan penelitian ini akan membantu pembuat aplikasi mengembangkan aplikasi mereka di masa depan.

Analisis Kerentanan Pada Domain Repository Unjaya Menggunakan Kerangka Information System Security Assessment Framework (ISAFF)

Alfirna Rizqi Lahitani, Ahmad Nurhidayat, Nofa Shintia, Muhammad Fahrur R — Tue, 28 May 2024 15:42:10 +0700

Vulnerability analysis on the Unjaya Repository website uses the ISSAF method for identifying and grouping identified vulnerabilities.. The purpose is to provide an in-depth understanding of the vulnerabilities that exist on the Repository site as a basis for the corrective steps needed to reduce security risks. The methods are information gathering, network mapping, vulnerability exposure, vulnerability grouping, IP addresses, active ports. Scanning using Nikto Scanner and Helium Security, 24 vulnerabilities detected in four levels, namely high, medium, low and informational. The results found at a high level of vulnerability in the form of disclosure of PII, at a medium level such as the absence of an Anti-CSRF Token, at a low level such as Application Error Disclosure, and at an information level such as Authentication Request Identified. This proves that there is a significant potential risk to the security of the Unjaya Repository site.
