Abstract

Mathematical communication, which involves the ability to express and understand mathematical ideas, is very important in learning. However, many conventional learning methods are less effective in improving these abilities. This study combines gamification-based flash card innovation with the TAPPS model to maximize social and cognitive interactions in mathematics learning, which is expected to have a positive impact on student engagement and understanding. This study aims to explore the application of gamification-based flash cards with the Think Aloud Pair Problem Solving (TAPPS) model to improve junior high school students' mathematical communication skills. The research method used is classroom action research with several cycles that include (Planning, implementation, observation and reflection). Based on the research that has been conducted in 2 cycles with the application of the TAPPS model assisted by gamification-based flash cards, with an average of 84.8% in the first cycle and 94.1% in the second cycle. So there is an increase in students' mathematical communication skills. Therefore, gamification-based flash cards can be used as a medium to improve students' mathematical communication.

Abstract

As part of the community environment, the school faces challenges in managing the growing amount of plastic waste. Through a project of making paving blocks from plastic waste, this study aims to help students learn geometry by integrating the concept of surface area of 3D shapes into real-life practice. Students took part in the project by designing and creating hexagonal prism-shaped paving blocks to cover the archery extracurricular area, which often gets muddy during rainy days. This study was conducted using a descriptive qualitative approach. Interviews with students and teachers, project process documentation, and observation of learning activities were all methods used to collect data. The results show that the Design Thinking approach supported students in understanding surface area in a more practical way, especially in calculating the dimensions and quantity of paving blocks needed. The project also encouraged students to be more aware of environmental issues.

Abstract

This research analyzes raw material inventory control at PT. Adhi Karya (Persero) Tbk AMP Medan Area, considering warehouse capacity limitations and demand fluctuations. The study employs the Economic Order Quantity (EOQ) and Period Order Quantity (POQ) models to determine optimal order quantity, ordering frequency, and total inventory costs. Results show that both models yield substantial cost efficiencies compared to the company’s current policy. The total inventory cost using the EOQ model is Rp630,499,314.50, while the POQ model results in Rp626,289,722.53. In contrast, the company’s current approach incurs a total cost of Rp1,648,260,123.80. Consequently, EOQ and POQ generate savings of Rp1,017,760,809.30 and Rp1,021,970,401.27 respectively. These findings indicate that both models offer effective and economical solutions for inventory control. Additionally, they help avoid overstock and stockouts while adapting to production demands and limited storage space, thus optimizing procurement strategies.

Abstract

This study was motivated by the previous learning process, which tended to be delivered uniformly without considering the varying ability levels of students. This approach resulted in low overall learning achievement at the class level. The objective of this study is to improve the mathematics learning outcomes of Grade VIII A students at SMPN 1 Mataram through the implementation of the Teaching at the Right Level (TaRL) approach, which is a learning strategy based on students’ ability levels. This research employs a Classroom Action Research (CAR) design, consisting of two cycles. Each cycle includes the stages of planning, implementation, observation, evaluation, and reflection. Data were collected through observation and learning outcome tests. The results of the study are as follows: (1) In the first cycle, the students' classical mastery reached 72.5%, with an average score of 73. These results did not meet the minimum success criterion for classical mastery, which is set at 85%. (2) In the second cycle, there was a significant improvement in learning outcomes, with classical mastery reaching 87.5% and an average score of 90. This indicates that the implementation of the Teaching at the Right Level (TaRL) approach can improve students' learning outcomes
