Abstract

AbstractGood inventory management is the key to success for every company, both companiesengaged in industry and trading companies. Managing inventory properly can make itpossible to use resources optimally and efficiently. Inventory is the main part of workingcapital, because it is the biggest investment in the production process or in other companies,therefore it is necessary to use a way to namely the current inventory model which is oftenfound one of them with the EOQ model (Economic Order Quantity), with a case. The problemlater is how to determine the supply of materials using EOQ, and how much the difference incosts occur with the EOQ model. The goal of all companies is to maximize the value of thecompany both economically and socially, from the case and discussion it turns out andproven that the EOQ model can be effective and efficient in the company.

Abstract

This study aims to improve students' numeracy skills in solving mathematical story problems through the implementation of the Cooperative Learning model in elementary schools. This study used a Classroom Action Research (CAR) approach, implemented in two cycles, each consisting of planning, implementation, observation, and reflection. The subjects were 25 third-grade elementary school students. Data were collected through numeracy tests, observation sheets, and documentation of learning activities. The results showed that the implementation of the Cooperative Learning model significantly improved students' numeracy skills. This improvement was evident in the increase in average numeracy test scores from cycle I to cycle II, as well as an increase in the percentage of learning completion. Furthermore, student engagement in the learning process also showed positive developments. Students became more active in group discussions, helped each other understand story problems, and were more confident in expressing their opinions and solutions. The Cooperative Learning model provides opportunities for students to learn collaboratively, enabling them to rely not only on individual abilities but also on the strengths of teamwork. This makes the learning process more meaningful, as students can connect mathematical concepts to real-world experiences through social interaction. Thus, the application of the Cooperative Learning model has proven effective in improving students' numeracy skills as well
