Abstract

Conventional marketing which is still predominantly carried out by female micro-entrepreneurs in Suka Mulya Village has limited market reach and low product selling value. This study aims to determine the most effective digital marketing strategy to increase the competitiveness of female MSME products using the Analytical Hierarchy Process (AHP) method. The four components of digital marketing explained are social media, marketplace, web platform, and social network. This study involved 30 respondents and used a paired comparison questionnaire. The results of the AHP calculation showed that social media had the highest weight preference of 53.88%, followed by marketplace (25.23%), web platform (14.64%), and social network (6.25%). The Consistency Ratio (CR) value of 0.033 (<0.1) indicates that the respondents' assessments are consistent and the calculation results are valid. These findings recommend a gradual digital marketing approach with an initial focus on social media, accompanied by ongoing training and mentoring. This study also contributes to the application of AHP for strategic decision making in the MSME sector.

Abstract

This study proposes the design and implementation of a smart hospital corridor gate prototype utilizing the ESP8266 microcontroller and Internet of Things (IoT) technology to enhance access control and visitor monitoring. With increasing foot traffic in hospitals, effective access management is crucial to prevent unauthorized entry, ensure safety, and maintain operational efficiency. The proposed system uses the ESP8266 as the main controller, enabling real-time monitoring and data transmission over a wireless network. The system integrates Radio Frequency Identification (RFID) technology to automate the identification process. Visitors are required to carry RFID cards or tags, which are scanned upon entry via an RFID reader installed at the gate. The captured data is then transmitted to a centralized server for real-time monitoring and storage, allowing hospital staff to efficiently track visitor activity. Additionally, to support health screening, the system incorporates a temperature sensor for automatic detection of body temperature and a motion-based servo sensor to detect visitor presence and movement in restricted areas. These sensor readings are also transmitted to the server and displayed through an integrated dashboard interface, providing clear and accessible information to hospital staff. Experimental results demonstrate that the system effectively accelerates visitor data acquisition, enhances surveillance, and supports early detection of health conditions. The integration of IoT and sensor-based automation enables hospitals to implement a more secure and responsive access control mechanism. This prototype holds significant potential for further development in building intelligent healthcare infrastructure and can be adapted for broader applications in environments that require stringent monitoring protocols.

Abstract

Brute force attacks are a common method used by attackers to breach authentication systems, both on Secure Shell (SSH) services and website login pages such as WordPress. In educational institutions, particularly at the Nurul Fikri Integrated Technology College, authentication system security is crucial for maintaining data confidentiality and integrity. Prior to this research, the system in use was not equipped with an automated defense mechanism capable of responding to brute force attacks quickly and effectively. This research aims to implement Fail2Ban, an open-source application designed to automatically block IP addresses that make failed login attempts exceeding a certain threshold. The research method involved testing two scenarios: an attack on the SSH service using Nmap, and an attack on the WordPress login page using a Python script. The Fail2Ban configuration set the maxretry parameters to five failed attempts, a findtime of 10 minutes, and a bantime of 3 minutes. The test results showed that Fail2Ban successfully blocked the attacker's IP address according to the specified parameters, thus preventing further login attempts. To enhance monitoring capabilities, Fail2Ban is integrated with Prometheus and Grafana using a combination of the Fail2Ban Exporter, Python scripts, and Push Gateway. This integration produces an interactive dashboard that displays metrics such as the number of blocked IP addresses, total failed login attempts, and the status of active blocks. This data visualization allows system administrators to monitor attack activity in real-time and take additional precautions if necessary. Thus, Fail2Ban implementation is not only effective in preventing brute-force attacks but also improves situational awareness and rapid response to security incidents in educational institutions.

Abstract

Traffic violations, such as exceeding the speed limit and inappropriate lane usage, are among the main factors causing accidents and congestion on toll roads. To improve traffic safety and efficiency, an automated monitoring system capable of detecting and analyzing violations quickly and accurately is needed. This research aims to develop and evaluate a detection system for speed limit violations and lane misuse by heavy vehicles using deep learning-based object recognition and tracking technology. The method used is the YOLO (You Only Look Once) framework for object detection and the Kalman Filter to track vehicle movement between frames, thereby refining position and speed estimates. The research data was obtained from CCTV video recordings installed along the toll road. The developed system is capable of detecting vehicles, calculating speed based on the shift between frames, and analyzing vehicle position in relation to lane usage regulations. The model evaluation results demonstrated quite good performance with an accuracy of 83.97%, a precision of 0.702, a recall of 0.757, and an F1 score of 0.758. The combination of YOLO and the Kalman Filter proved effective in detecting and tracking vehicles in real time, with adequate accuracy and efficient processing speed. This study concludes that a deep learning-based system can be an innovative solution to support automated traffic monitoring on toll roads. Implementing such a system has the potential to help reduce traffic violations, prevent accidents, and improve driving safety. Furthermore, this study provides recommendations for further development for integration with intelligent transportation technology to support more adaptive and sustainable traffic management.
