Abstract

Improving numerical literacy in elementary schools is a major concern in the world of education in Indonesia. Several studies have emphasized the importance of using innovative and creative learning media to improve students' understanding of mathematical concepts and mathematical skills. This article examines the application of innovative learning media to improve numerical literacy in elementary schools. The method used in this study is a literature review based on articles obtained from Google Scholar and Garuda searches, with a total of 30 relevant articles over an 8-year period, namely from 2018 to 2025. The research process was carried out by identifying, studying and synthesizing research results that discuss innovative strategies in the field of numerical learning. The results of the analysis show that the use of technology-based media, educational games and interactive methods can consistently improve students' learning motivation and numerical skills. These findings emphasize the need for further development of innovative learning media to improve students' numerical literacy at the elementary level, as well as a review for references as a means to improve learning resources. This study recommends a new path in the form of using digital media as a form of innovative learning media to improve elementary school students' numerical literacy

Abstract

Bagapit Chess (Catur Bagapit) is a traditional strategy board game originating from the Kalimantan region of Indonesia. Despite its rich cultural heritage and strategic depth comparable to international Chess, Bagapit Chess remains largely unstudied from a computational intelligence perspective. This paper presents the development of an Artificial Intelligence (AI) model for the Bagapit Chess engine using the Random Forest Regressor (RFR) algorithm. The AI model is trained to evaluate board positions and generate competitive move decisions through a heuristic evaluation function augmented by machine learning. A dataset of 15,000 annotated game positions was constructed from expert gameplay, encoding board features including piece Material Advantage, Chess Movement, Defense Stance, mobility, and Attack Coverage across the 8×8 Bagapit board. The Random Forest Regressor model was integrated with a Negamax search tree enhanced by Alpha-Beta Pruning to achieve efficient and intelligent move selection. The trained model achieved an R² score of 0.9134, a Mean Absolute Error (MAE) of 0.0872, and a Root Mean Squared Error (RMSE) of 0.1104 on the test set. In engine evaluation against a rule-based baseline, the AI model won 84.2% of games under standard time control. This study contributes to the digitalization and preservation of Indonesian traditional games and demonstrates the applicability of ensemble machine learning to non-standard board game engines.
