PREDIKSI HARGA EMAS MENGGUNAKAN ALGORITMA SEASONAL AUTO REGRESSIVE INTEGRATED MOVING AVERAGE

Indra Ikhsani — 2025-04-02

This study aims to develop a gold price prediction model using the Seasonal Autoregressive Integrated Moving Average (SARIMA) method. The model is designed to address fluctuations in gold prices influenced by seasonal factors by utilizing historical gold price data as the basis for forecasting. The data used has undergone selection and transformation stages within the Knowledge Discovery in Databases (KDD) framework. The model Evaluation was conducted using two main metrics, namely Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE), to measure prediction accuracy and performance. The results indicate that the SARIMA model is capable of providing high-accuracy predictions, as evidenced by an RMSE of 17.393 and a MAPE of 0.65863, reflecting a relatively low prediction error. These findings affirm the reliability of SARIMA in handling time series data with seasonal patterns while contributing to the development of commodity price prediction methods, particularly for gold. The developed model is expected to serve as a reference for investors, market analysts, and other stakeholders in formulating more measured and data-driven investment strategies.

THE IMPLEMENTATION OF DESIGN THINKING AS A DESIGN METHOD IN EDUCATIONAL GAME DEVELOPMENT

D'Riski Maulana — 2025-04-02

The popularity of educational games as learning tools continues to rise, thanks to their ability to create engaging and interactive learning experiences. However, the development methodologies for these games have not kept pace with their increasing popularity. Many developers face challenges in choosing approaches that are not only effective but also adaptive to user needs. This study examines the potential of design thinking as an alternative methodology for developing educational games. As an innovative approach rooted in UI/UX design, design thinking offers an iterative, user-centered framework through five key stages: empathize, define, ideate, prototype, and test. By conducting literature reviews, comparative analyses, and case studies, this research proposes a design thinking-based methodology for educational game development. Validation was conducted through the development of an educational game focused on pathfinding algorithms. Evaluation results using the User Experience Questionnaire (UEQ) indicated scores of 2.15 for attractiveness, 1.77 for dependability, and 1.81 for stimulation, all categorized as excellent. Meanwhile, the aspects of novelty (1.76), perspicuity (1.95), and efficiency (1.87) were categorized as good. These findings suggest that the design thinking-based methodology holds promise as an effective and adaptive approach for educational game development.

Ameliya Sukma Lestari — 2025-04-02

The payment system that still uses a calculator often causes miscalculations, while raw material management often faces obstacles such as undetected out-of-stock items. The manual reporting process makes it difficult to identify income details, so the flow of income and expenses becomes unclear. To address these issues, a website-based restaurant ordering and management system was designed using the waterfall method. This system aims to reduce errors in daily transaction records, assist employees in the payment process, and produce accurate transaction reports to prevent data accumulation and loss. Test results show that this website has high performance with a Performance score of 91, meaning the page loads quickly. Additionally, the Best Practices value reaches 100, indicating excellent technical quality and security. However, the Accessibility score of 60 highlights the need for improvements to make the system more inclusive and accessible to users with disabilities. This system is expected to significantly improve the operational efficiency of the restaurant.

This research is motivated by the many companies that still use manual systems in managing stocks and orders, which causes operational inefficiencies. In particular, state-owned trading companies experience challenges in managing logistics and administration that are constrained by fragmented manual systems. This research identifies knowledge gaps related to the development of technology-based stock and order management systems, especially using the Laravel framework in the context of large companies. The research methodology used was descriptive qualitative with observation and in-depth interviews in the logistics and administration division of the company for four months. The results showed that the developed system was able to improve the efficiency of stock management, speed up the recording process, and minimize errors that occurred in order management, comparing much better than the previous manual method. The implication of this research is that the use of a web-based system can provide better accessibility for users on various devices, as well as offer a user-friendly interface to improve the company's operational efficiency.
