Abstract

The SmartCampus application is still built with a monolithic architecture, where all components are tightly integrated into one unit. The increasing complexity of user scalability and service demands within the information system with a monolithic architecture is evident in the application's declining performance. In this research, a performance analysis is conducted by implementing refactoring from a monolithic architecture to microservices using the decomposition and strangler patterns. The Decomposition pattern divides the monolithic application into several business domains based on their main service categories, while the strangler pattern breaks down the business domains into microservices by replacing specific functions with new services through the stages of transform, co-exist, and eliminate. Once the new functionalities are ready, the old components are deactivated, and the new services are put into operation. The application's feasibility and quality considerations are assessed using the ISO/IEC 25010 model, which comprises eight characteristics: functionality suitability, performance efficiency, compatibility, usability, reliability, security, maintainability, and portability. The performance of the resulting microservices application is tested using different performance testing types, such as load testing, spike testing, stress testing, and soak testing. Microservices showing satisfactory performance improvements will be isolated using container technology to optimize application resource efficiency and anticipate long-term needs

Abstract

Improving time efficiency and reducing work risks are crucial in palm oil mill operations. Two vital factors in palm oil mill operations are CST temperature and effluent pond level. Both of these factors have a significant impact on mill efficiency. Extreme temperatures, either too high or too low, can disrupt the settling and separation process of water, oil and sludge. In addition, overflowing effluent pond levels are often missed by technicians, so checking must be done manually. This research aims to develop a monitoring system that can monitor the temperature of the CST in safe conditions and measure the level of the waste pond in real-time by utilizing Internet of Things (IoT) technology. This control system relies on components such as the NodeMCU ESP8266 microcontroller, DS18B20 temperature sensor, and HC-SR04 proximity sensor. The method used is the design and manufacture of a prototype monitoring system. Field test results show that this system is able to make comparisons with manual measurement methods. In testing the CST temperature sensor and the waste pool level sensor, the accuracy rate reached 100%. The temperature was successfully monitored with a safe limit of 89°C, while the waste pool level was monitored through the monitoring website. This Internet of Things-based monitoring system has shown significant potential in improving the efficiency and safety of palm oil mill operations, and enables mill operators to effectively conduct remote real-time monitoring.

Abstract

This research delves into sentiment analysis for digital election campaign advertisements using the Multinomial Naive Bayes approach. The study addresses the limitations of standard sentiment analysis methodologies in capturing the intricacies of public sentiments toward political ads. The dataset, sourced from Kaggle, encompasses 3000 records with sentiments categorized as positive, neutral, and negative. The Multinomial Naive Bayes model demonstrated a substantial accuracy increase from 92% to 96%, outperforming the standard Naive Bayes model. Precision, recall, and F1-score metrics consistently improved across sentiment categories. While dataset representativeness and cultural specificity pose limitations, the research contributes significantly to sentiment analysis methodologies in politically charged digital environments. Future research recommendations include exploring advanced NLP techniques, incorporating real-time data from diverse social media platforms, and addressing ethical considerations in political sentiment analysis. The outcomes emphasize the importance of tailored methodologies for enhanced accuracy in understanding sentiments expressed in digital election campaign advertisements.

Abstract

Generally, patients are unaware of their hypertension condition before having their blood pressure checked. One out of three Indonesians suffers from hypertension, and this figure continues to rise annually. Hypertension is often referred to as the silent killer because individuals with high blood pressure do not exhibit symptoms. This study aims to classify hypertensive patients in an effort to reduce the prevalence of hypertension in Indonesia by aiding in early detection of the disease and increasing awareness of hypertension among the Indonesian population. By using the Naïve Bayes method and implementing data discretization of risk factors, the dataset used comprises 11,627 health examination records of 4,434 participants from the Framingham Heart Study (FHS) organized by the National Institutes of Health. The classification method utilizes the Naïve Bayes Algorithm, and data discretization is performed using the CART (Classification and Regression Trees) method. The system provides an estimation of the probability of hypertension occurrence based on input factors/symptoms, where Naive Bayes achieves an accuracy rate 84.28%.

Abstract

Just-In-Time production system in the form of kanban has been implemented in many production processes in order to optimize the production output. Internet of Things (IoT) has been integrated into production system in digitalizing production processes as well as obtaining and gathering real-time information in the factory floor through sensors, actuators, and network. In this study, an application of IoT into kanban and production system was proposed. The proposed electronic kanban system composed of Radio Frequency Identification (RFID) cards and readers, QR code and reader, microcontrollers, digital displays, and server. In this system, the kanban card is replaced by an RFID card. All workstations in the production process are equipped by RFID readers, microcontrollers, and displays to show relevant instructions to the operator. The microcontrollers are connected to a server to send information of the RFID card scanned by them and the time when the card was scanned. The latter information is used for tracing each of the products produced in each of the workstations. The proposed electronic Kanban system was implemented to an assembling process consisting of 7 workstations. The system was able to replace the conventional kanban card with RFID and electronic displays and performing the unit tracing capability.

Abstract

The selection of prospective librarians is necessary to make the right decisions and determine the most suitable individual to meet the library's needs. However, in facing the complexity of changes in the information environment and technological developments, the FST library often needs help selecting prospective librarians using manual calculations, which can affect the effectiveness of the library head and staff in selecting. This research was conducted at the FST Library of the North Sumatra State Islamic University. This time, the researchers used the Weighted Aggregated Sum Product Assessment (WASPAS) method to select prospective librarians. The criteria used are communication skills (C1), mastery of technology (C2), customer service (C3), limited skills (C4), and lack of adaptability (C5). Then, the alternatives used were five samples of prospective librarians who registered at the FST library. The calculations using the WASPAS method showed that the alternative Nazla Maulida (A04) was a suitable candidate to become a librarian at the FST library with a total score of 0.854.

Abstract

Currently, personalized learning has become a necessity in the learning process. Research and implementation of personalization in the planning phases and implementation phases of learning have been extensively studied. However, that research has not yet reached the application stage in the learning assessment phase. Providing homogeneous examination material to each student has not considered the characteristics of learners. Even though the achievements from the assessment phase will provide a measure of the quality of the learning process as a whole. This research has analyzed the individual characteristics model, which is derived as a benchmark for identification of the information and characteristics of the test material, which is then formulated into a classification model based on supervised learning. This study identified text dataset questions and labeled unbalanced multi-classes. This presents a challenge to carry out experiments to find the most optimal data training strategy, the results provide optimal strategy combination results Logic: ENS, Verbal: ENS, Visual: CW+RES+ENS, Natural: CW+RES+ENS. Accuracy measurement results Logic (SVM): 0.85, Verbal (LR) 0.87, Visual (LR) : 0.93, Natural (NN) 0.93.

Abstract

Abstract- Libraries generally provide lockers for users to store their luggage. Lockers in general still use conventional security by using manual locks. Currently, UIN Suska Riau Central Library still uses conventional key security which is considered easy to duplicate, lose, and damage. The purpose of this research is to improve locker security for user convenience and security through a system integrated with RFID, dual camera monitoring, and telegram notification. This tool has a CRUD (Create, Read, Update, Delete) system embedded in the telegram application managed by the admin. Admin can register, delete, and monitor locker user activities. This tool can identify registered and unregistered RFID tags properly. When a registered user accesses the locker, the system will send a picture of the user and a message to the telegram. Meanwhile, when an unregistered user accesses the locker 3 times incorrectly, the device will send the user's picture and message to the telegram and an alarm will sound for 3 seconds as an indication of an attempted locker break-in. The speed of information notification from the Internet of Things system has a delay in sending images with stability in the range of 3 - 4 seconds with relatively strong internet provider speed stability. Keywords— locker security, internet of things, RFID, dual camera monitoring, telegram
