Analysis of the Needs for a Recording System for Raw Materials and Finished Products at the Om Ending Convection

2025-12-21T12:35:23+00:00

This web-based convection information system was developed using the Software Development Life Cycle (SDLC) Waterfall model to address the main issues in manual stock management within convection businesses, including inaccuracies in recording and the risk of loss for both raw materials and finished products. The system is designed to provide an integrated solution, including multi-level user authentication (admin, owner, warehouse staff, and production staff), real-time summary dashboard, management of raw materials, finished products, supporting items, as well as a warehouse module for recording incoming and outgoing goods with early warning for low stock. Its implementation utilizes Native PHP and MySQL database on the XAMPP environment, having undergone requirements analysis through interviews and observations, design of DFD levels 0-3 and ERD, intuitive UI/UX implementation, and manual black-box testing that validates functional accuracy. Overall, the system accelerates the recording process by up to 70%, significantly improves stock data accuracy, and supports strategic decision-making through exportable automatic audit reports, thereby reducing the likelihood of human error in convection business operations. This development not only optimizes the efficiency of textile SMEs like Konveksi Om Ending but also provides a scalable foundation for expansion, including predictive analytics integration and mobile access, ensuring long-term competitiveness in the digital era.

The Application of the Question-and-Answer Method to Enhance the Critical Thinking Skills of High School Students

The low critical thinking skills of 10th-grade high school students regarding arithmetic sequences and series are attributed to a lack of student engagement during the mathematics learning process. This study aims to determine the effect of implementing the question-and-answer method on improving students' critical thinking skills in the topic of arithmetic sequences and series. A quantitative approach was employed using a quasi-experimental design—specifically, a pretest-posttest control group design. The research subjects consisted of 26 10th-grade students from MA Wahid Hasyim during the 2025/2026 academic year. Data collection involved pretests, posttests, and observation sheets. Data analysis was conducted using normality and t-tests with the aid of IBM SPSS Statistics. The results indicate that the question-and-answer method successfully improved students' critical thinking skills, evidenced by the rise in the average score from 75 on the pretest to 88 on the posttest. Furthermore, the t-test yielded a significance value of 0.001 (p < 0.05), demonstrating that the question-and-answer method had a significant impact on enhancing students' critical thinking skills regarding arithmetic sequences and series.
