Abstract

Kantor Telkom Akses Langko merupakan salah satu kantor telkom yang berada di Mataram, kantor telkom langko saat ini belum mempunyai SOP dalam hal pengiriman data. Kantor telkom langko memiliki berbagai divisi di dalamnya salah satunya adalah admin. Admin bertugas untuk menginput data ke BROMO yang dikirimkan oleh petugas lapangan. Namun saat ini alur pengiriman data dari teknisi belum teratur yaitu masih menggunakan aplikasi telegram yang terkadang pihak admin langsung meminta ke teknisi tanpa melalui leader terlebih dahulu sehingga alur aliran data menjadi tidak baik yaitu dapat kehilangan dan kerusakan data. Untuk itu perlu adanya Standar Operasional Prosedur (SOP) untuk mengatur aliran data secara urut dari teknisi, leader, admin, hingga sampai ke site manager. Melalui penerapan SOP yang baru, diperoleh hasil survei dari 57 responden yang mengatakan bahwa aliran data lebih struktur dan memudahkan dalam pencarian data.

Abstract

Information system security is increasingly crucial with the rise of cyber threats. This study identifies and evaluates security risks in education service systems using STRIDE and DREAD-based Threat Modeling. STRIDE identifies threats such as spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege, while DREAD assesses risk based on potential damage, ease of exploitation, affected users, and likelihood of detection. The analysis showed that information disclosure and elevation of privilege were the highest risks, mainly due to the permissive CORS configuration. Testing using Burp Suite revealed high-level vulnerabilities allowing unauthorized access and data leakage. To address this, mitigations in the form of CORS policy validation, HTTP method restrictions, data encryption, and role-based authentication were implemented. Simulation results after mitigation showed a significant reduction in security issues, such as critical issues dropping from 6 to 1. This research confirms STRIDE and DREAD are effective in identifying and evaluating security risks, providing a strong basis for designing mitigation strategies to maintain educational service security.

Abstract

Mataram University as a tertiary institution has the duties and functions of implementing the Tri Dharma of Higher Education, namely education and teaching, research, and community service. Such efforts are not only carried out and become the obligation of lecturers alone, but also for students. The use of technology in the village of North Surabaya is still lacking, the village administration system is still carried out manually and the dissemination of village information is still uneven. With the existence of a village website, it is hoped that administrative management and distribution of information will be evenly distributed. The understanding of the North Surabaya village community about digital is still very minimal, of course there must be efforts that needs to be done to increase human resources regarding digitization in order to take advantage of the potential that exists in the village of North Surabaya. The implementation of the work program is carried out using a participatory method by collaborating with various existing stakeholders, the output of the real work lecture program is assisting SSID development, making a Local Area Network (LAN) master plan, and creating a temporary village website in the village of North Surabaya. For 45 days in North Surabaya Village we have carried out the main program, namely creating a temporary website containing village infographics and making a LAN master plan which later the village can use as a reference when installing a LAN network at the village office. In addition to the main work program, there is also an additional work program, namely the socialization of "Cute Internet" with the aim of developing human resources in North Surabaya Village to make positive use of the internet.

Abstract

Android has become the most widely used operating system for mobile devices, playing a crucial role in supporting the tourism sector. As tourism in Indonesia grows, the demand for quick and easy access to information for travel planning has increased. However, concerns about the security of user data in Android applications have emerged. This study focuses on penetration testing of tourism-related Android applications in Lombok to identify vulnerabilities, particularly based on the OWASP Top 10 Mobile Risks. Using static analysis with the Mobile Security Framework (MobFS), two critical vulnerabilities were identified: Insecure Data Storage and Insufficient Cryptography. Penetration testing revealed that although there was a risk related to insecure data storage, no sensitive user data was found in the application's database. The application was also found to use outdated encryption (CBC with PKCS7 padding), which could expose it to padding oracle attacks. This research emphasizes the need for robust security measures in mobile applications within the tourism sector.

Abstract

The increasing use of Wi-Fi in higher education also brings security risks, such as Evil Twin Attacks that trick users into connecting to fake access points. This study aims to assess the vulnerability of Universitas Mataram’s Wi-Fi network to such attacks using a multihop model and to propose technical improvements. An ethical penetration testing method was applied using a NodeMCU ESP8266 with Deauther firmware, tested across 13 campus locations. Observed variables included the number of connected devices, user interaction with phishing pages, deauthentication success, and captured credentials. The results reveal that five out of 13 locations (38.46%) were vulnerable, where users were redirected to fake SSIDs and entered credentials, even though most deauthentication attempts failed. These findings highlight that attack success depends not only on deauthentication but also on firmware variation and AP configuration. The study implies the need for network security audits, firmware standardization, stronger authentication with full encryption, and enhanced user awareness to reduce phishing risks.

Abstract

Many devices connected to a network inevitably result in clashes between communication signals. These collisions are an important factor that causes a decrease in network performance, especially affecting Quality of Service (QoS) like throughput, Packet Delivery Ratio (PDR), and end-to-end de- lay, which has a direct impact on the success of data transmission by potentially causing data loss or damage. The aim of this research is to integrate the Dynamic Power Transmission (DPT) algorithm into the Optimized Link State Routing (OLSR) routing protocol to regulate the communication sig- nal strength range. The DPT algorithm dynamically adapts the signal coverage distance based on the density of neighboring nodes to reduce signal collisions. In our protocol, the basic mechanism of a DPT algorithm includes four steps. The Hello message structure of OLSR has been modified to incorporate the ”x-y position” coordinate field data. Nodes calculate distances to neighbors using these coordinates, which is crucial for route discovery, where all nearby nodes can process route re-quests. The results of this research are that DPT-OLSR improves network efficiency in busy areas. In particular, the DPT-OLSR routing protocol achieves an average throughput enhancement of 0.93%, a 94.79% rise in PDR, and reduces end-to-end delay by 45.69% across various variations in node density. The implication of this research result is that the algorithm proposed automatically adapts the transmission power of individual nodes to control the number of neighboring nodes within a de-fined range. This effectively avoids unwanted interference, unnecessary overhearing, and excessive processing by other nodes, ultimately boosting the network’s overall throughput.
