Abstract

Student cooperatives (kopma) are cooperatives whose members are students from a particular university. In relation to the flow of funds in and funds out of kopma, the decision support system is a crucial tool for analyzing calculations of insufficient or excess funds.“This can minimize potential losses that arise as a result of inaccurate calculations of the flow of funds that have been collected. One effort to generate a decision support system is a fuzzy logic approach. This research aims to build a system that can determine cooperative turnover well using the fuzzy mamdani method.”“In this research, defuzzification was carried out using the centroid method with the help of MATLAB fuzzy toolbox r2016a software.””From the results of research that has been carried out by entering monthly income variables from January to December”in each sector, namely rental, photocopying and mini markets, it will produce turnover decision outputs of profit, break even and loss. Uses fuzzy mamdani to get output and has a membership function.”

Abstract

Wireless Sensor Networks (WSNs) have rapidly expanded across various applications. However, WSNs are highly vulnerable to attacks, one of which is Distributed Denial of Service (DDoS) attacks, posing a significant threat to many WSN systems. Therefore, a security technique is needed to protect WSNs from such attacks. This study aims to effectively detect DDoS attacks on WSNs using Machine Learning (ML), specifically with the Support Vector Machine (SVM) method. The testing in this study employs precision, recall, F1-score, confusion matrix, and ROC curve metrics. The results indicate the best performance in detecting Grayhole attacks. The Precision, Recall, and F1-score metrics for these attacks are all 1.0, meaning that Grayhole attacks are perfectly detected by the intrusion detection system utilizing the SVM method. Furthermore, based on the confusion matrix results, the system successfully identified Grayhole attacks with a Precision value of 99.7% and a Recall of 99.6%, indicating that only a few error detections occurred. However, the AUC test results for DoS attacks yielded a score of 0.5, suggesting that the system is unable to detect DoS attacks effectively.

Abstract

The nutritional status of toddlers is an important indicator reflecting the welfare level of society. In Indonesia, the prevalence of toddlers with poor nutrition and stunting remains a significant issue that requires special attention. This study aims to develop a toddler nutritional status classification system using the K-Nearest Neighbor (KNN) method as a tool for early stunting detection. The KNN method was chosen due to its ability to classify data based on proximity. The data used in this study were obtained from the Cileunyi Health Center, with anthropometric parameters including Age, Weight, and Height. The system was implemented using the PHP programming language and MySQL database. The test results showed that the system achieved an accuracy of 66.67% for Weight-for-Age (W/A) classification and 100% for Height-for-Age (H/A) classification. Thus, this system is expected to be an effective tool for healthcare professionals in the early detection of stunting in toddlers, allowing for timely and appropriate interventions.

Abstract

­­­­­­­­­Klinik Afrina Dental Care, operating in Simpang Empat District, Asahan Regency since 2006, offers a variety of dental care services. This study aims to improve service quality through the application of the Servqual method in a web-based information system, which measures five dimensions: Tangibles, Reliability, Responsiveness, Assurance, and Empathy. The analysis results indicate that the overall service quality exceeds patient expectations. The "Assurance" dimension recorded the largest gap (10.308), indicating that assurance and trust are highly appreciated by patients. Conversely, "Reliability" showed the smallest gap (5.385), highlighting the need for improvement in reliability. Although the overall service is satisfactory, certain aspects related to reliability require more attention to bridge the gap between expectations and reality.

Abstract

The construction industry demands more concrete, resulting in increased mining of concrete components. Consequently, the availability of natural resources to meet the demand for concrete is decreasing. Therefore, there are various ways to create new concrete mixtures using waste materials. In this research, fly ash and blood cockle shells were used as partial replacements for cement and fine aggregates, as these two waste materials have not been properly utilized. Test results over 28 consecutive days showed variations in normal concrete of 5%, BKF 7.5%, BKF 7.5%, and BKF 10% with 25.84 MPa, 29.28 MPa, 27.15 MPa, and 24.92 MPa, respectively. The consecutive slump test results for normal concrete variations of 5%, BKF 7.5%, BKF 7.5%, and BKF 10% were 80 millimeters, 85 millimeters, 100 millimeters, and 76 millimeters, respectively. The consecutive slump test results for normal concrete variations of 5%, BKF 7.5%, BKF 7.5%, and BKF 10% were 80 millimeters, 85 millimeters, 100 millimeters, and 76 millimeters. The water absorption test results for normal concrete of 5%, BKF 7.5%, and BKF 10% were 2.81%, 2.85%, 2.79%, and 2.78%, respectively, over 28 consecutive days.
