Abstract

This study aims to identify the similarity of thesis titles by applying the Mahalanobis Distance method which is known to be effective in measuring the distance between vectors by considering data distribution and correlation between variables. In its implementation, each thesis title is represented in vector form using the TF-IDF scheme before calculating the level of similarity using Mahalanobis Distance. The test results show that this method is able to produce similarity values between titles, but its performance has not shown optimal effectiveness in the context of similarity classification. The highest precision value obtained of 1.0 indicates that this method is quite reliable in identifying pairs of titles that are truly similar. However, the low recall value of only 0.5 indicates that there are many pairs of similar titles that fail to be detected, resulting in an F1-score value of only 0.638. This shows an imbalance between the system's ability to detect similarity and its classification accuracy. Although the accuracy value is relatively high, ranging from 0.958 to 0.988, these results do not necessarily reflect the overall effectiveness of the method in handling minor classification errors. Testing of the threshold parameters also shows that a value of 0.1 provides the best performance compared to other threshold values because it is able to maintain a balance between precision, recall, F1-score, and accuracy.

Abstract

This research aims to develop a temperature and humidity monitoring system for the server room at the Palembang Industrial Standardization and Services Center (BSPJI) using an Android-based microcontroller. This system monitors server room environmental conditions in real-time to maintain equipment performance and reliability. The microcontroller integrated with the Android application can collect temperature and humidity data using appropriate sensors, which can be accessed and analyzed remotely via the Android application. Temperature and humidity measurement results can also be forwarded via in-app notifications to notify users of abnormal conditions. This research combines microcontroller technology, environmental sensors, and Android applications to provide a monitoring solution that is effective and responsive to environmental changes in the server room. Hopefully, this system can help maintain server stability and performance at BSPJI more efficiently

Abstract

The storage system that occurs in the Cooperative Office is still reasonably conventional. It is proven that storing and sharing files among employees still use Flash; it becomes a problem if the Flash occurs error / corrupt file then the stored file will be lost, and also vulnerable to viruses if the Flash is often connected to a computer then it takes a media/system that can store, share, or become a data center at the Cooperative Office. So, with this, the author has the idea to design private cloud storage using IaaS (Infrastructure as a Service). The test results show that the cloud storage system works well and is responsive. There are no significant lags in accessing the system, and the data transfer rate when saving files or sharing between employees is also satisfactory. The use of the cloud storage system also proved easy and intuitive for the staff and employees who took part in the trial. Implementing the Cloud Storage system at the cooperative and SME Office of South Sumatra province has successfully made centralized data storage for staff and employees in the environment. With this system, all personal and work-related data and Office archives can be accessed and stored efficiently
