Model Difusi Teknologi Dan Pelatihan Penerapan Pencetakan Tiga Dimensi Berbahan Pla Untuk Pendidikan Pangan Dan Lingkungan Anak Usia Dini
Abstract
ABSTRACT
Three-dimensional (3D) printing with polylactic acid (PLA) can support the provision of concrete learning media in early childhood education, yet its implementation raises concerns regarding the accuracy of sustainability claims, safety, and the complexity of technology adoption. This study aimed to develop a technology diffusion and training model for implementing PLA-based 3D printing in early childhood food and environmental education. A research and development approach was employed by adapting the initial stages of design-based research, comprising needs analysis, model development, expert validation, and product refinement. Validation involved two early childhood education experts, two materials experts, and two safety experts using 36 assessment indicators, and the data were analysed through multidimensional means, feasibility percentages, and quality gap analysis. The study produced a six-phase model supported by four role levels, four activity zones, and competency-based training modules. Feasibility reached 90.00% according to early childhood education experts, 84.17% according to materials experts, and 80.83% according to safety experts, with a combined feasibility of 85.00%. The largest quality gaps were found in waste management and the physical safety of learning media. The model is conceptually feasible, with priority revisions on safety and waste management, while physical product safety and learning effectiveness require further testing.
