Abstract

Payment of Educational Development Contribution (SPP) is one of the routine activities carried out in the school environment, including at SMK Negeri 1 Sikur. The payment process which is still done manually causes various problems, such as late recording, human error, and lack of transparency of information to parents. This study aims to develop a web-based SPP payment information system to simplify the school financial administration process and increase data efficiency and accuracy. The system development method used is the Waterfall model which includes the stages of needs analysis, system design, implementation, testing, and maintenance. This system is built using the PHP programming language with a MySQL database and is accessed via a web browser. The test results using the black-box method show that all system functions run well according to user needs. With this system, the SPP payment process becomes more effective and efficient, and provides more transparent access to information to schools and parents. It is hoped that this system can be a digital solution that supports better school financial governance.

Abstract

The rapid development of e-commerce demands a recommendation system that can help users find products that match their preferences. This study aims to implement the K-Nearest Neighbor (K-NN) algorithm in a product recommendation system to improve the personalization of e-commerce services. The K-NN algorithm works by finding similarities in behavior between users based on purchase history, then recommending products based on these similarities. The dataset used in this study consists of user transaction data, product categories, and user data, which are then processed through a cleaning and normalization stage before analysis. Testing was carried out using several variations of K values ​​to find the optimal parameters. The experimental results showed that the value of K = 5 gave the best performance with an accuracy of 87% and an F1-score of 84.5%. In addition, the Cosine Similarity method proved effective in measuring similarities between users in sparse data. The system built is able to provide relevant recommendations with efficient computing time, showing the potential to be applied in small to medium-scale e-commerce platforms. However, the system still has limitations in handling new users (cold-start), so further development with a hybrid approach is recommended. This study shows that the K-NN algorithm is a feasible and efficient approach in user behavior-based product recommendation systems.

Abstract

Computer device damage is often an obstacle for users, especially for those who do not have the technical knowledge to diagnose the problem. To overcome this problem, a system is needed that is able to provide an initial diagnosis quickly and accurately. This study aims to design and develop a web-based expert system that can help users determine the type of computer damage using the Certainty Factor (CF) method. The CF method is used to calculate the level of certainty of the symptoms entered by the user based on previously formulated expert knowledge. This system is built using the PHP programming language and MySQL database, and is designed to be widely accessible via the internet network. The test results show that the system is able to provide diagnostic results with an adequate level of accuracy and is close to the results of direct analysis by technicians. Thus, this system can be an effective tool in the process of identifying computer damage and providing initial recommendations for handling before users take the device to a professional technician.

Abstract

The development of information technology provides great opportunities for Micro, Small, and Medium Enterprises (MSMEs) to expand the reach of their product marketing through digital media. However, many MSMEs still do not have an effective digital platform to market their products independently. This study aims to design and build a web application for marketing MSME food products with a search feature based on the Boyer-Moore algorithm, which can speed up the product search process and increase system efficiency. The system development method used is the Waterfall model, including the stages of needs analysis, design, implementation, testing, and maintenance. The application is built using HTML5, CSS3, JavaScript, PHP, and MySQL technologies, with the Boyer-Moore algorithm implemented in the search feature to speed up keyword matching. The test results show that the application runs well, is responsive, and is able to display search results quickly, especially when the amount of product data increases. Performance testing shows that the Boyer-Moore algorithm has a faster response time than conventional search methods. This application is expected to be a practical and efficient digital solution in helping MSMEs market food products independently and competitively in the digital era.
