Abstract

The rapid advancement of wireless network technology and the Internet of Things (IoT) ecosystem in the industrial sector carries significant security risks, particularly regarding vulnerabilities within the management frame protocol. This study aims to evaluate the resilience of wireless network infrastructure against communication disruptions at the protocol level, specifically deauthentication attacks, at PT Jaring Solusi Persada (JSP) Tulungagung Branch. Applying a Research and Development (R&D) method with a Prototyping approach , empirical and real-time testing was conducted using a low-power ESP8266 Deauther Version 2 device as a penetration medium across 15 different access points (APs). Quality of Service (QoS) parameters, including throughput, latency, and packet loss, were measured using Wireshark software to analyze network performance degradation in detail. The experimental results reveal that deauthentication attacks inflict a highly destructive impact on vulnerable devices. Out of the 15 tested APs, 6 units (40%) consisting of consumer-grade devices (such as TP-Link, ZTE, and Totolink) were declared vulnerable because they did not support or activate the Management Frame Protection (MFP/IEEE 802.11w) feature. On these vulnerable devices, the attack successfully triggered complete client disconnections, a drastic 70% drop in throughput (from 567 kbps to 170 kbps), extreme latency spikes ranging from 100 to 300 ms, and a packet loss of 15%. Conversely, 9 AP units (60%), dominated by Ruijie Enterprise business-class devices, successfully withstood the attack and maintained stable network connections due to superior hardware specifications and better defense configurations. This study recommends upgrading network security standards to WPA3 and strictly enabling the Protected Management Frames (PMF) feature to ensure the company's operational continuity.

Abstract

The advancement of Internet of Things (IoT) technology in industrial sectors has driven the need for more accurate and integrated automation systems, particularly in production weighing processes. PT. Jaring Solusi Persada Tulungagung Branch required improvements in measurement accuracy, real-time data recording, and monitoring of rice milling operations. This research aims to design and develop an IoT-based digital weighing system using ESP32 and load cell to enhance operational efficiency and reduce weighing errors. The research method applied is Research and Development (R&D) using a Prototyping approach, encompassing hardware design, software development, load cell calibration, and direct system testing in the operational environment. The system utilizes the HX711 module as a signal amplifier for the load cell, with ESP32 as the main microcontroller to process weight data and transmit information in real-time via Bluetooth to a Flutter-based mobile dashboard application. Testing results indicate that the system achieved 0% error rate in weighing accuracy tests across six trials with load variations of 1–20 kg. Actuator response tests showed an average response time of 0.80 seconds with an average overshoot of 0.72% of the target weight, within acceptable tolerance for on-off control systems. IoT integration with real-time monitoring via Bluetooth successfully enabled live weight tracking and production history recording. This system demonstrates significant improvement in work efficiency, minimization of human error, and support for faster and more accurate decision-making in rice milling production

Abstract

The manual and subjective process of determining color printing costs and recording sales transactions at Penjilidan Express, which resulted in inconsistent pricing, recording errors, and reduced operational efficiency. This research focuses on developing a web-based cashier system equipped with a Print Color Analysis feature to support more objective and consistent printing cost estimation and streamline transaction management. The system was developed using the Scrum framework and implemented with the Laravel framework based on the Model-View-Controller (MVC) architecture. The Print Color Analysis feature calculates the percentage of RGB/CMYK color composition from digital files in JPG, PNG, and PDF formats to automatically estimate printing costs. The developed system was evaluated through Black Box Testing across seven core functional features. The results demonstrated that every tested feature performed as expected, achieving a 100% success rate and confirming that the system fulfilled all predefined functional requirements.The developed system is expected to improve the consistency of printing cost calculations, streamline transaction processing, and minimize the risk of errors in sales data recording. Therefore, the proposed system can serve as an effective solution to support operational efficiency, pricing transparency, and business digitalization in printing service companies.

Abstract

Perkembangan teknologi digital telah mendorong transformasi dalam pengembangan kapasitas Sumber Daya Manusia (SDM), terutama melalui platform pembelajaran daring yang lebih fleksibel dan mudah diakses. Namun demikian, masih terdapat kesenjangan dalam pengalaman pengguna yang dipengaruhi oleh faktor gender, khususnya ketika sistem digital tidak dirancang secara inklusif. Penelitian ini bertujuan mengevaluasi tingkat usability sistem digital pengembangan SDM berbasis gender menggunakan metode Remote Moderated Usability Testing (RMUT). Pendekatan penelitian yang digunakan adalah deskriptif kuantitatif dengan melibatkan 20 partisipan (10 laki-laki dan 10 perempuan) yang dipilih melalui simple random sampling. Proses pengujian dilakukan secara daring melalui aplikasi Zoom, di mana partisipan diminta menyelesaikan enam skenario tugas: login dan navigasi, mengikuti pelatihan, mengerjakan evaluasi, mengunggah tugas, mengakses sertifikat, dan memberikan umpan balik. Data dikumpulkan melalui observasi interaksi, rekaman layar, dan kuesioner SUS serta UEQ, kemudian dianalisis menggunakan SmartPLS. Hasil penelitian menunjukkan bahwa usability sistem secara umum berada pada kategori baik, ditunjukkan dengan skor SUS rata-rata di atas 70. Namun, ditemukan perbedaan signifikan berbasis gender. Partisipan laki-laki menunjukkan performa penggunaan yang lebih lancar dengan skor SUS dan UEQ lebih tinggi pada sebagian besar dimensi, seperti daya tarik, efisiensi, kejelasan, keandalan, stimulasi, dan kebaruan. Sebaliknya, partisipan perempuan mengalami lebih banyak hambatan, terutama pada aspek desain antarmuka mobile, keterbacaan teks, dan fleksibilitas fitur unggah file. Metode RMUT terbukti efektif dalam mengungkap perbedaan pengalaman pengguna secara lebih mendalam dibandingkan penggunaan kuesioner semata, karena mampu menangkap proses interaksi dan kendala aktual yang dialami pengguna.
