Abstract

Efforts to strengthen school discipline can be done in various ways. For example, at the middle school level, points for violations committed by students are calculated based on the rules set by the school. The number of fault points counted varies from warning to calling the parent at the highest level, and notifying the maximum number of fault points to the parent. SMA Muhammadiyah 7 serbelawan has issued a code of conduct. The school will apply penalty points for all infractions committed by students in an attempt to enforce disciplinary action. To improve teacher performance in dealing with problem students, the authors designed a system for calculating student violation points using the oriented objects technology method. By using the object oriented technology method, it will build a system systematically and regularly in order to achieve a goal based on the abstraction of existing objects and the presence of this system will certainly greatly help teacher performance, especially counseling guidance teachers and counseling guidance teachers, problems in recapitulating all student violations that occur in Muhammadiyah 7 Serbelawan High School. With a system that has been computerized and integrated with databases, it will be able to facilitate the process of finding student data that violates and conducting counseling easily and documents are stored neatly in the database.

Abstract

Clustering and classification technologies are pivotal in data analysis, helping to uncover hidden patterns in complex datasets. Despite their broad applications across fields such as pattern recognition, market segmentation, anomaly detection, and weather prediction, these techniques face significant limitations. Clustering methods like K-Means assume known cluster numbers and data distributions, while classification approaches such as K-Nearest Neighbors (KNN) rely heavily on the quality of labeled data. These challenges are particularly pronounced in the context of dynamic weather data, which exhibits high variability and complexity. This research addresses these limitations by integrating probabilistic multi-class labeling with an adaptive K-Means clustering approach. Probabilistic labeling allows data points to belong to multiple classes, reflecting the nuanced nature of overlapping weather conditions. Adaptive K-Means dynamically determines the optimal number of clusters, overcoming traditional constraints. By combining these methods with KNN classification, the proposed approach enhances the accuracy of weather classification. KNN leverages cluster centroids and class probabilities to provide more precise predictions. This approach provides a robust foundation for further research and optimization of adaptive methods applicable to other complex data types. Ultimately, the proposed model contributes significantly to advancing data analysis methods, particularly for dynamic and multi-class datasets like weather data.

Abstract

Mr.Boba is a company that sells various variants of drinks such as durian juice, boba and so on. The sales process is still done manually or handwritten and payment transactions can also only be done in cash. One of the obstacles that employees have faced is that customers want to pay non-cash but do not provide qris and the like. When employees process reports every time the store closes, it takes quite a long time. With this web-based point of sales system, it really helps employees to be faster and more efficient in their work. This system was built with the RAD method which is structured from requirement planning, workshop design and implementation and the framework used is the Laravel framework. Testing on this system shows good results with the blackbox testing method. The results of this study aim to facilitate employees to record both cash and non-cash transactions and computerized reports to umkm owners. Keywords : point of sales, multipayment, laravel, RAD, blackbox testing

Abstract

Teachers are the initial milestone in the creation of a nation with quality young generation, both in the academic and non-academic fields. To determine or choose the best teacher, a decision support system for selecting the best teacher is made to appreciate the work performance that has been done while being a teaching staff, and is expected to increase motivation so that teachers can improve their performance. For this reason, a decision support system is needed that can analyze several teachers according to the existing teacher selection profile. The Profile Matching process is carried out to determine teacher recommendations in the Best Teacher Selection System based on 3 variables, namely intellectual aspects, work attitude aspects and general aspects. The result of the selection process is in the form of a teacher's final score as a recommendation for decision makers to choose the right teacher in the selection of the best teacher.

Abstract

The development of computer technology nowadays has progressed very rapidly in line with the development of computer and telecommunication technology, making communication more open and information exchange faster, however not all developments in communication technology have had a positive and beneficial impact. One of the negative impacts of technological development is the existence of wiretapping, with the presence of encrypted tapping, the security aspect in exchanging important information. The problem of sending messages (e-mail), be its agencies, education, government, private and others, must contain confidential information, so encryption of the message is required. Encryption of information is important to support information security, because it can guarantee message security. Therefore, encryption is needed by users who have information that is guaranteed its confidentiality. One way to store data sent via email is to use cryptography. The Affine Cipher is an extension of the Caesar Cipher which multiplies the plaintext by a value and adds a shift. Creating an application by implementing cryptography using the Affine Cipher is one way of maintaining the confidentiality of information and is very important. The results obtained from this research are that the application created can change the content of existing messages and can store information that is available when sending e-mails. The process of encoding messages using the Affine Cipher algorithm is successfully used to hide secret messages into text.
