Rudolf F.A. Ginting — 2024-06-30

Automatic parking registration has become a focal point in the research and development of modern urban transportation systems. In this context, image-based vehicle license plate recognition plays a vital role in facilitating efficient and accurate parking registration processes. This research aims to develop an image-based vehicle license plate recognition system for automatic parking registration applications using Optical Character Recognition (OCR) technology. The methods employed include vehicle image acquisition, image preprocessing, license plate segmentation, text extraction using OCR, and license plate character recognition. Testing was conducted using a dataset of vehicle images captured under various lighting conditions and angles. Experimental results demonstrate that the proposed system is capable of recognizing vehicle license plates with a high level of accuracy, even under varying lighting conditions and distorted license plates. Implementation of this system is expected to enhance efficiency in automatic parking registration and reduce manual involvement in the process.

Analisis Penggunaan Fitur Vicon (Video Conference) pada E-Learning Ilmu Terhadap Kelancaran Pembelajaran Daring Di Fakultas Ilmu Komputer UPN Veteran Jawa Timur

Online learning has become an integral part of higher education in today's digital era, especially following the COVID-19 pandemic. Video conferencing (Vicon) technology plays a crucial role in this transition, enabling direct interaction between teachers and students without the need for physical presence in the classroom. This study aims to analyze the use of Vicon features in the context of online learning and its impact on the smoothness of the learning process. Data were collected through a questionnaire administered to students of the Faculty of Computer Science at UPN Veteran Jawa Timur, with the System Usability Scale (SUS) method employed for calculation. The collected data were then qualitatively analyzed to determine the effectiveness of Vicon use by identifying usage patterns, obstacles faced, and student perceptions of its impact on the learning process. Analysis of the SUS scores, usage patterns, challenges, and student perceptions revealed a low average SUS value. This indicates that while Vicon facilitates direct interaction and effective material delivery, there are still significant technical obstacles and low participation rates. These findings suggest the need for improvements in the technical aspects of Vicon and strategies to increase student engagement in online learning environments.

Pharmacy product searches are becoming increasingly important in the context of public health needs. In this digital era, users are often faced with challenges in finding pharmacy products that suit their preferences and needs. In this research, we explore the implementation of multi-criteria methods in pharmacy product searches to increase relevance and search efficiency. Developing a pharmacy product search system that utilizes multi-criteria methods to consider various factors such as description, efficacy, price, availability. Through the integration of this method, the system can present search results that are more personalized and relevant to users. Evaluation of system performance through practical trials and found that the use of multi-criteria methods can improve the quality of pharmacy product search services. This research contributes to the development of more sophisticated and effective pharmacy product search technology, as well as increasing user satisfaction in meeting their health needs

This research aims to create an electronic circuit to detect ammonia gas levels using the MQ-135 sensor, making it easier for farmers to detect ammonia gas levels, which can hinder the growth of broiler chickens if too high. The research was conducted at the Karang-karangan Village Broiler Chicken Farm. This type of research uses Research and Development (R&D) for the manufacture and design of ammonia gas detection equipment on farms. The application of the ammonia gas detector consists of several steps: data collection, system analysis, design, manufacture, and system testing. The problem that occurs in broiler farms is farmers' ignorance of ammonia gas levels before spraying. The research results show that the detection tool can be used well, and farmers can easily operate it. Farmers must first find out the ammonia gas levels on the farm before spraying disinfectant, and if the sensor detects levels exceeding the normal safe limit, the buzzer will sound and display the value on the LCD screen.

Sonia Afdilah — 2024-06-30

In today's digital era, the security of the user identification system must be considered, therefore the use of blockchain technology can be utilized in such a way. Blockchain is a dynamic and interactive computer program to support solving problems in identifying users. Apart from that, blockchain technology can be used to secure data which is now very vulnerable to viruses in computers or networks. Blockchain technology provides a solution by providing a strong and reliable information security system. Blockchain technology can be used to ensure the integrity and validity of stored data. This can be done by storing data in blocks that are connected to each other and using encryption to maintain privacy. In addition, the decentralized system in blockchain technology makes it difficult to change or delete by irresponsible parties. Blockchain technology is very suitable for increasing the security of user identification systems, in this research the author found other research related to blockchain technology which is useful for data security, therefore the author invites readers to use blockchain technology for the security of user identification systems and data security.
