Abstract

Random user mobility on a WLAN network allows users to move away from the access point (AP) that serves them so it has an impact on the possibility of users losing connectivity to the communication network. This study aims to simulate handover performance at the Faculty of Science and Technology UIN North Sumatra to maintain network QoS by using the comparison method of RSSI AP1 and AP2 values ​​and comparing RSSI values ​​with Threshold values. The computational results on the RSSI comparison method with the threshold are carried out at a distance of 15 meters, and the comparison of the RSSI AP1 values ​​has dropped below the RSSI AP2 values ​​with values ​​of -64.35 dBm and -62.75 dBm respectively. Meanwhile, in the threshold method, the RSSI AP1 value is below the threshold so that the user connectivity service will be transferred to AP2. This research is expected so that the Faculty of Science and Technology can obtain information on the quality of WLAN network services through mobile devices.

Abstract

Meeting management is a series of activities aimed at planning, organizing, implementing and evaluating a meeting or meeting to achieve certain goals. The Bureau of Government and Regional Autonomy at the Office of the Governor of North Sumatra functions as a technical institution that handles government affairs and regional autonomy under the coordination of the governor. It is not uncommon for this bureau to hold meetings every day. When holding a meeting, meeting management such as attendance lists and meeting minutes are still done manually using paper and recorded by hand and then stored in a storage room. Manual processes like this tend to be time consuming and can increase the risk of errors. Seeing this problem, the need for the process of checking information on availability and confirming the borrowing of a room to be used for meetings takes a relatively longer time so it becomes an obstacle. The aim is to design and implement an effective information management system to increase the efficiency of meeting minutes in government bureaus and regional autonomy. This system was built by modeling several UML diagrams such as use case diagrams, activity diagrams, and class diagrams. It is hoped that the Bureau of Government and Regional Autonomy at the Office of the Governor of North Sumatra can improve the quality of education which can be realized through the appropriate and efficient use of information technology.

Abstract

The system currently used experiences problems in handling recipient and delivery data, customer data, and inventory data which are recorded on paper and only copied by the admin to the company computer. These problems can result in product calculation errors, problems in recording and reporting product recipients and deliveries, and in several months the product in and out can reach the target. There are often differences in inventory. This is caused by a helper or admin error. The warehouse department is recording, receiving and sending products. In addition, the accumulation of large numbers of files can make it difficult to find the product data you need, and searching files can take time and interfere with other tasks. The aim of this research is to develop an inventory management application that can manage recipient or delivery data, inventory data, and delivery data using visual modeling used in building object-oriented systems and waterfall system development methods. This is about developing a website that is created to simplify incoming goods data and outgoing goods data so that it can help business processes in the company.

Abstract

All information in data exchange transactions on communication networks travels through the network infrastructure. The network infrastructure sends various types of data, including text, images, and documents with various extensions. These documents may be private and confidential. Therefore, it is crucial to have a message security option that is not only user-friendly but also has a high level of security system complexity. The purpose of this research is to build a text message security system using the Advanced Encryption Standard (AES) algorithm on mobile devices. We can utilize it as a security solution to safeguard text messages received through mobile devices. The AES security algorithm is known to have reliability in processing data encryption and decryption. The research will describe components such as the design, implementation, and analysis of application requirements. Important features include encryption, decryption, and key management in addition to an easy-to-use UI. The research findings show that this program successfully secures text messages while maintaining the confidentiality and integrity of the data sent. Additionally, we adjusted the application's parameters to align with mobile device standards, ensuring consistent encryption and decryption procedures that users can easily operate. For application testing, we use the black box testing method to ensure that the design and application function as intended, adhere to security regulations, and provide a positive user experience. This study's results suggest that AES-based mobile messaging security applications can serve as a tool to fulfill the secure communication expectations of mobile users.

Abstract

This research aims to analyze public sentiment towards Starlink through tweets collected using the hashtag "starlink." The data crawling process was successful in collecting 1888 tweets. However, upon checking and processing the data, we reduced the number of valid and relevant tweets to 416. This reduction occurred due to duplicate data and the use of common keywords. We performed sentiment classification using the Naive Bayes model, yielding the following sentiment distribution: We classified 287 tweets (68.99%) as positive, 112 tweets (26.92%) as neutral, and 17 tweets (4.09%) as negative. The model performance evaluation shows good results with a recall of 0.80, precision of 0.90, F1 score of 0.83, and accuracy score of 0.80. The results of this study indicate that the majority of tweets related to Starlink have positive sentiments, indicating a generally favorable public perception of the service. A small proportion of tweets showed neutral and negative sentiments, which can provide valuable input for service improvement. The Naive Bayes model is able to classify sentiment with fairly high accuracy, making it one of the most effective tools for sentiment analysis.
