Abstract

This study developed an Android-based educational game to teach children about waste management, with an adaptive reward system using Sugeno fuzzy logic. The aim of the study was to increase student motivation and engagement in environmental learning by providing rewards tailored to player performance. The development method referred to the Game Development Life Cycle (GDLC), covering the development stages up to beta testing. Media expert validation results showed good game quality in terms of visual appearance and ease of use, with an average score of 4.6/5. Material validation also showed the suitability of the material for learning objectives with a score of 4.7/5. Trials with 26 primary school students resulted in an average score of 4.6/5 for ease of use and 4.8/5 for visual appeal. The Sugeno fuzzy logic-based reward system proved effective in adjusting rewards to player performance. Test data showed that 70% of students received 3 stars, 20% received 2 stars, and 10% received 1 star. This system increased student motivation and engagement in learning. This research contributes to the development of fuzzy technology-based educational games by demonstrating the great potential of Sugeno fuzzy logic in creating adaptive reward systems that enhance learning. This game is expected to be an effective alternative in teaching waste management and can be expanded to other educational topics.

Abstract

Effective inventory management is crucial in manufacturing industries to ensure smooth production and minimize operational costs. This study aims to design and implement an inventory control system based on the Continuous Review System (CRS) method at Naf’a Bakery, a small business located in Desa Canggu, Kediri. The implementation of CRS is expected to optimize raw material inventory, reduce storage costs, and avoid the risks of stockouts or overstocks. The methods used include observation, interviews, and demand data analysis to calculate the reorder point (ROP), optimal order quantity (EOQ), and safety stock. The results show that the implementation of CRS can reduce storage costs by approximately 30% and ordering costs by about 25%, while improving operational efficiency compared to the previous manual system. The CRS-based information system allows Naf’a Bakery to monitor inventory in real-time, ensuring that raw materials are always available at optimal levels and providing flexibility to adapt to demand fluctuations. Thus, this system not only enhances inventory management accuracy but also reduces waste and improves profitability. This study provides significant contributions to the development of more efficient inventory control systems for small and medium enterprises.
