Abstract

Lumban Pea Timur is one of the villages in Balige District, Toba Samosir Regency, North Sumatra Province. Village development is currently inseparable from the support of information technology, almost every village requires information technology to improve services to the community. The process of conveying information by the village to the resident, namely from the sub-district head to the village head reaches the resident. Processes like this often lead to inaccurate information. All existing regional potentials must be disseminated to show their superiority. Each district has an area called a sub-district and village. The rapid development of the world of communication technology has had a tremendous impact on the pattern of people’s lives. Information systems have made people’s lives dynamic and fast. With the facilities provided, encourages people to take advantage of information and communication technology to assist in their daily activities. The village government of Lumban Pea does not yet have a website address. This has resulted in information owned by the village that cannot be accessed by the wider community, causing this village to be very left behind. In this increasingly advanced technological era, a website-based information system can be implemented in East Lumban Pea village to overcome the above constraints. With the existence of a village information system, the community can directly access the various kinds of information presented. Likewise, village leaders can directly provide or update information related to the village they are fostering. All forms of information regarding population management can be accessed on the village information system page.

Abstract

Fuzzy C-Means (FCM) merupakan algoritma klastering  yang sangat baik dan lebih fleksibel dari algoritma klastering konvensional. Selain kelebihan tersebut, kelemahan utama algoritma ini adalah sensitif terhadap pusat klaster. Pusat klaster yang sensitif mengakibatkan hasil akhir sulit di kontrol dan FCM  mudah terjebak  pada optimum lokal. Untuk mengatasi masalah tersebut, penelitian ini memperbaiki kinerja FCM dengan menerapkan Particle Swarm Optimization (PSO) untuk menentukan pusat klaster yang lebih baik. Penelitian ini diterapkan pada klastering sentimen dengan menggunakan data berdimensi tinggi yaitu ulasan produk yang dikumpulkan dari beberapa situs toko online di Indonesia. Hasil penelitian menunjukkan bahwa penerapan PSO pada pembangkitan pusat klaster FCM dapat memperbaiki performa FCM serta memberikan luaran yang lebih sesuai. Performa klastering yang menjadi acuan  adalah Rand Index, F-Measure dan Objective Function Value (OFV). Untuk keseluruhan performa tersebut, FCM-PSO memberikan hasil yang lebih baik dari FCM. Nilai OFV yang lebih baik menunjukkan bahwa FCM-PSO tersebut membutuhkan waktu konvergensi yang lebih cepat serta penanganan noise yang lebih baik.AbstractFuzzy C-Means (FCM) algorithm is one of the popular fuzzy clustering techniques. Compared with the hard clustering algorithm, FCM is more flexible and fair. However, FCM is significantly sensitive to the initial cluster center and easily trapped in a local optimum. To overcome this problem, this study proposes and improved FCM with Particle Swarm Optimization (PSO) algorithm to determine a better cluster center for high dimensional and unstructured sentiment clustering. This study uses product review data collected from several online shopping websites in Indonesia. Initial processing product review data consists of Case Folding, Non Alpha Numeric Removal, Stop Word Removal, and Stemming. PSO is applied for the determination of suite cluster center. Clustering performance criteria are Rand Index, F-Measure and Objective Function Value (OFV). The results showed that FCM-PSO can provide better performance compared to the conventional FCM in terms of Rand Index, F-measure and Objective Function Values (OFV). The better OFV value indicates that FCM-PSO requires faster convergence time and better noise handling.

Abstract

This study examines the LSTM-based model for processing spam in text data. Spam poses several dangers and risks, both for individuals and organizations. Spam can be a nuisance that hampers both individual and organizational productivity. Much spam contains fraudulent or phishing attempts to obtain sensitive information. Spam detection using deep learning involves the utilization of algorithms and deep neural network models to accurately classify messages as either spam or not spam. Typically, spam detection systems use a combination of these methods to improve the accuracy of identifying spam messages. This study applies the Bi-LSTM deep learning model to sequentially process text (sequencing). The performance of the model is determined based on the loss and accuracy. The data used are the Spam SMS and Spam Email datasets. The test results show that the Bi-LSTM model demonstrates better performance on all tested datasets. Bi-LSTM is able to capture textual patterns from both the context and the text itself, as it can combine information from both directions. The test results prove that the Bi-LSTM model is more effective in text comprehension. So we need to use Snort to maintain network security. Snort is a useful software for observing activity in a computer network. Snort can be used as a lightweight Network Intrusion Detection System (NIDS). Detection is carried out based on the rules that have been described by the administrator in the directory rules contained in the configuration file. Snort can analyze real time alerts, where the mechanism for entering alerts can be in the form of a user syslog, file or through a database. So we can detect attacks on computer networks early.

Abstract

The assessment of lecturer performance at Indonesian Methodist University is a crucial component in maintaining and enhancing the quality of education. Manual assessment processes encounter various challenges, including inefficiency, prolonged durations, and the potential for human error. Therefore, a digital solution is necessary to simplify and optimize the assessment process. This research aims to design and develop a web-based lecturer performance assessment questionnaire application that enhances efficiency, accuracy, and ease of use in the assessment process at Indonesian Methodist University. The application design is conducted using the Unified Modeling Language (UML) method, which involves creating use case diagrams, class diagrams, and activity diagrams. This approach facilitates the design of a well-structured and documented system, thereby streamlining the development and implementation processes. The research findings indicate that the questionnaire application designed with UML significantly improves the efficiency and accuracy of the lecturer performance assessment process. Additionally, this application simplifies user access to online questionnaires and generates reliable assessment reports.
