Abstract

Extracting book metadata by retyping the identity of the book, such as the author's name, book title, publisher, and several other identities, is a routine that is carried out repeatedly at the Polewali Mandar district library, this activity takes much of time, using several staff and it turns out that this activity has much potential for input errors. Errors in extracting book metadata will result in errors in the book repository system database, resulting in difficulty finding and using books or book data information. This problem can be solved by creating a book metadata extraction system using image processing technology and OCR. This study aims to design a scanner technology to extract book metadata. Accuracy is carried out in 2 stages, the first validation of image extraction results using the ROC method and the second validation by directly matching the result of extracting the book's metadata with the actual book. The results of this study indicate that the system has worked with an accuracy of 98.78% with an average detection time of 1.49 seconds and has succeeded in presenting the extraction results on the website page. Thus the metadata extraction system with the OCR method can be applied to libraries to input book data.

Abstract

A tornado is a form of extreme weather caused by differences in air pressure and temperature in the atmosphere. This phenomenon can cause loss of life and psychological disorders. To overcome this serious impact, a system that is able to monitor the condition of the surrounding environment in real-time and provide early warning is needed. This research aims to design an Internet of Things (IoT) system for real-time monitoring of wind speed and direction as well as environmental conditions that is effective for providing early warning of natural disasters. Testing and calibration methods were carried out by comparing IoT devices with standard tools. Additional tests were conducted on the anemometer to evaluate the consistency of wind speed at certain heights and at locations adjacent to the coast and some distance from the coast. The results of this IoT device design demonstrate its ability to detect temperature, humidity, air pressure, wind speed, and wind direction, and send real-time data to the monitoring system. This research confirms that the web-based monitoring system is effective in monitoring environmental conditions and sending early warnings when the system detects tornado characteristics.

Abstract

The UNASMAN Language and Character Development Institute (LBPK) is used by all UNASMAN students to improve their English skills so they can continue their studies abroad and as alumni can later compete in the world of work with other alumni both nationally and internationally. This research aims to group student scores in the English Sunset program at the Unasman Language and Character Development Institute (LBPK) using the K-Means method. The K-Means method was chosen because of its effective ability to group data based on similarity of attributes, making it possible to identify groups of students with similar value characteristics. Student score data is collected, processed and analyzed using the K-Means algorithm to determine the optimal number of clusters. The research results show that students can be grouped into three main clusters: students with high scores, medium scores, and low scores. This information provides valuable insight for LBPK in designing more targeted teaching strategies and providing additional support for student groups in need. Feasibility analysis from a technological and operational perspective shows that this system can be implemented with adequate infrastructure and sufficient training support for staff and lecturers. This research confirms that the K-Means method can be used effectively to improve the qualitys of learning at LBPK Unasman.
