Abstract

Business competition in the field of selling school uniforms in Medan is currently very tight. UD Rohana is a business unit engaged in the sale and purchase of school uniforms. At UD Rohana itself, at every moment the increasing demand often experiences problems in stocking and distributing existing uniforms to consumers (shops / retailers). This of course will be a loss for UD Rohana in carrying out its business turnaround. For this we need a system that can monitor and check the condition of the stock of goods in several stores. So that if there is an increase in demand or sales in one shop where the demanded goods are accumulated in another shop, then UD Rohana can distribute them to the stores that need them. Supply chain management in the business world has adopted a lot of Supply Chain Management (SCM). With implementing SCM, we can control the existing business processes at UD Rohana. For methods in system development using Rapid Application Development (RAD) and for system business processes using the Unified Modeling Language (UML). The results of this study are the development of a school uniform distribution information system successfully developed by adopting the SCM system.

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.

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.
