Integrating Local Culture and Sustainability in Educational Play Tools: Conceptual Design of a Punokawan Puzzle with PLA-Based 3D Printing

Abstract

Educational Play Tools (EPT) hold significant importance in fostering young children’s cognitive, motoric, social, and emotional growth, while simultaneously functioning as instruments for cultural transmission. Nonetheless, the global toy industry continues to rely heavily on conventional plastic-based materials that contribute to environmental degradation and lack integration of indigenous cultural values in their designs. This research seeks to formulate a conceptual prototype of a contemporary EPT that synthesizes sustainable materials, technological innovation, and cultural contextualization. The study adopts a Qualitative Conceptual Design Research framework encompassing literature synthesis, design evaluation, and conceptual visualization through Blender 3D, followed by prototype fabrication using 3D printing methods. The developed prototype features a puzzle inspired by the Punokawan figures, embodying Javanese philosophical wisdom; it is designed to stimulate children’s cognitive and motor abilities while reinforcing cultural identity formation. The results demonstrate that polylactic acid (PLA) presents a viable eco-friendly substitute with substantially reduced carbon emissions, though its implementation remains challenged by factors such as material resilience, production cost, and regional availability. Moreover, 3D printing enables the creation of customizable, precise, and pedagogically responsive educational designs. This study contributes to theoretical discourse on sustainable and culturally integrated EPT design while offering practical insights for educational institutions and commercial development. Despite being limited to conceptual modeling, the research establishes a foundational framework for future innovations in environmentally responsible, educationally sound, and culturally embedded play-based learning tools.
