Classification of Ceramic Roof Tiles Using the CNN Method

Achmad Danu Zakaria — 2026-02-11

The research on tile classification using Convolutional Neural Network (CNN) aims to improve and address issues in the sorting process within the tile manufacturing industry. The accuracy level in manual sorting processes is very low due to errors caused by visual limitations and physical fatigue. By leveraging the capabilities of Convolutional Neural Network (CNN), a model was developed to classify tiles. This research involved several processes, including literature review, dataset collection, dataset splitting, preprocessing, Convolutional Neural Network (CNN) design, training, testing, and result evaluation. The study used 69 tile images divided into three classes: KW 1, KW 2, and KW 3. The results of testing the Convolutional Neural Network (CNN) on tile classification using 100 epochs with a data split of 90% training and 10% validation yielded an accuracy rate of 100%.

Utilizing Midtrans as A payment Gateway for Non-Cash Transactions

Mochammad Rizal Aditya — 2026-02-13

Increasingly, including payments in school e-canteens. One of the payment methods that can be used is to use a payment gateway such as Midtrans. This study aims to evaluate the use of Midtrans as a payment gateway for noncash transactions in school canteens using the waterfall method. This study uses the waterfall method to develop a payment system using Midtrans in the school canteen e-canteen. Data was collected through interviews with schools and e-canteen users as well as observations of the transaction process using Midtrans. Data analysis was performed using a qualitative descriptive method. This information system was built using the PHP programming language with the MSQL programming language and the Laravel framework using the SDLC (Systems development life cycle) method, which is a method that refers to the models and processes used to develop software systems and describe processes.

Ari Topan Iqbal Madagaskar — 2026-02-13

The rapid development of information technology strengthens the need for efficient system integration in sales management at the Point of Sale (POS) in Sky Park Hill Cafe, Kedungudi. This study explores the application of API (Application Programming Interface) technology to enhance interoperability between the POINT OF SALE (POS) application and other systems. APIs enable more efficient and real-time data exchange between various system components, facilitating accurate transaction recording and timely sales reporting. With the implementation of APIs, it is expected that Sky Park Hill Cafe can improve operational efficiency, increase data transparency, and enhance customer satisfaction through a better shopping experience and more responsive services.

Web-Based Online Exam Application for Junior High Schools Case Study: SMP Hasyim Asyari Tulangan)

David Eka Ramadhan — 2026-02-13

Technological developments have had quite rapid consequences in the field of education, the application of technology in the form of information systems, such as the use of online examination systems can be applied in the field of education. The online exam system is part of the distance learning information system via internet technology. The exams held by most educational institutions (in this case schools) are standardized. Like the exam system implemented at HASYIM ASHARI JUNIOR HIGH SCHOOL which still uses manual methods in data management, especially exam data management. HASYIM ASHARI JUNIOR HIGH SCHOOL really needs an information system at this time. This makes the final assessment contain a subjective element by involving human opinion. The aim of creating an online exam application system is to increase the speed and simplicity of the exam evaluation process. Examiners no longer check individual participant answer sheets and then calculate scores, but the software transfers scores to a database with automatic calculations based on participant answers. The method used in this research is the waterfall method and application testing uses the UAT (User Acceptance Test) method. The result of this research is the creation of a web-based online exam application for junior high schools that can provide assessment results in real time.
