Abstract

This study aims to obtain attack evidence and reconstruct commonly used address resolution protocol attacks as a first step to launch a moderately malicious attack. MiTM and DoS are the initiations of ARP spoofing attacks that are used as a follow-up attack from ARP spoofing. The impact is quite severe, ranging from data theft and denial of service to crippling network infrastructure systems. In this study, data collection was conducted by launching an test attack against a real network infrastructure involving 27 computers, one router, and four switches. This study uses a Mikrotik router by building a firewall to generate log files and uses the Tazmen Sniffer Protocol, which is sent to a syslog-ng computer in a different virtual domain in a local area network. The Trigger, Acquire, Analysis, Report, Action method is used in network forensic investigations by utilising Wireshark and network miners to analyze network traffic during attacks. The results of this network forensics obtain evidence that there have been eight attacks with detailed information on when there was an attack on the media access control address and internet protocol address, both from the attacker and the victim. However, attacks carried out with the KickThemOut tool can provide further information about the attacker’s details through a number of settings, in particular using the Gratuitous ARP and ICMP protocols.

Abstract

According to reports in 2021 by Kaspersky, requests for investigations into suspicious network activity, such as ARP Spoofing, which can result in sophisticated attacks, reached up to 22%. Several difficulties with examining network systems have been overcome thanks to network forensic investigations. This study aims to perform a network forensic analysis of ARP spoofing attacks using Wireshark forensic tools and Network Miner with a sniffer design process to capture traffic on the router side. In order to gather reliable evidence, this study employs the TAARA method as a network forensic investigation process. Based on the research conducted, it can be demonstrated that an attack took place from eight PCAP files. The information that was gathered, such as the IP address and MAC address of the attacker, the IP address and MAC address of the target, and the date and time of the attack are examples of evidence information that was gathered. This study also shows that network forensic operations can use the Wireshark forensic tool to obtain more detailed data.

Abstract

Fiber optic cable network security is a crucial aspect in ensuring the quality of service and sustainability of telecommunications infrastructure. One important element in the installation of such a network is the selection of the type of Drop Core (DC) cable used, especially in distribution areas that are prone to physical and environmental disturbances. This study discusses the comparison between two types of DC cables commonly used, namely AC-OF-SM-1B (DC cable with 1 strand) and AC-OF-SM-1-3SL (DC cable with 3 strand), in the context of effectiveness on fiber optic network security. This study was conducted using direct field observation methods, supported by discussions with technicians in the field, and evaluation of historical data on disturbances and damage from the use of both types of cables. The findings show that AC-OF-SM-1-3SL has a stronger structure, is able to withstand tensile loads and external pressure better, and is more resistant to environmental disturbances such as strong wind gusts and intervention from human activities. Meanwhile, AC-OF-SM-1B cables are lighter and more economical but have a higher level of vulnerability to external disturbances. These findings are expected to be a technical reference in making decisions regarding the selection of cable types in fiber optic network projects, especially in areas with a high risk of physical disruption.

Abstract

Radiografer adalah tenaga kesehatan profesional yang mengoperasikan peralatan medis berbasis radiasi seperti LINAC dan CT Simulator, khususnya di instalasi onkologi radiasi rumah sakit. Proses perekrutan radiografer memerlukan pendekatan sistematis agar sesuai dengan kebutuhan klinis dan operasional. Penelitian ini bertujuan membangun sistem pendukung keputusan (SPK) menggunakan metode Multi-Attribute Utility Theory (MAUT) untuk membantu seleksi tenaga radiografer secara objektif. MAUT digunakan karena mampu menangani banyak kriteria dan menghasilkan perangkingan alternatif berdasarkan nilai utility. Kriteria yang digunakan meliputi pendidikan terakhir, pengalaman kerja, komunikasi dan etika wawancara, penguasaan alat radioterapi, penggunaan software RIS/PACS, serta sertifikasi tambahan. Bobot ditentukan melalui diskusi bersama ahli dari instalasi onkologi dan SDM. Hasil penelitian menunjukkan bahwa kandidat A2 dan A3 memiliki nilai utility tertinggi sebesar 0,80, diikuti A1 dengan 0,70, sehingga direkomendasikan sebagai 3 kandidat radiografer di Instalasi Onkologi Radiasi RSUD dr. Kanujoso Djatiwbowo Balikpapan. Sistem ini terbukti dapat meningkatkan keakuratan seleksi, mengurangi subjektivitas, dan mempercepat proses rekrutmen. SPK ini berpotensi diterapkan lebih luas dan dikembangkan dalam bentuk aplikasi berbasis web ataupun mobile dengan penambahan variabel seperti uji praktik atau psikotes.

Abstract

Virtual Local Area Network (VLAN) is an effective solution for improving network performance and efficiency in educational environments, particularly in computer laboratories. This study aims to implement and evaluate VLAN at the Computer Laboratory of Universitas Mulia using a simplified action research approach involving a single intervention cycle. The initial diagnosis revealed that the conventional flat network topology resulted in a broad broadcast domain and reduced performance under high traffic conditions. Through VLAN segmentation, the laboratory was logically divided into five segments based on functionality. Evaluation was conducted using throughput measurement and Quality of Service (QoS) indicators, including packet loss, delay, and jitter, based on TIPHON standards. The results indicated consistent improvements in data flow and stability, with reduced packet loss under 0,3% and average delay and jitter remaining below 20 ms across all segments. In addition to technical improvements, interviews with the network administrator highlighted significant benefits in bandwidth management and traffic control during examinations. This study demonstrates that a simplified approach can be replicated in similar educational institutions with limited resources and provides a foundation for more structured and controlled network development.
