Abstract

This research aims to test the results of 3D printing using Polylactic acid (PLA) filament on surface roughness and tensile strength. Experiments were carried out by adjusting the differences in printing fill density for the pattern used. Filling density uses variations of 60%, 80%, and 100%. The tensile test is used to measure the tensile mechanical properties of polymers (σ). The roughness test is obtained to determine the average surface roughness (Ra), root mean square roughness (Rq), and ten-point height (Rz). The test specimen uses the ASTM D638 type 4 standard model and size. The nozzle diameter is 0.4 mm, the temperature is 220 °C, and the heat bed temperature is 60 °C. The mechanical properties test results of the printing pattern showed that the zigzag pattern had the highest yield strength, maximum load, and elongation values, namely 0.97 N/mm2, 52.99 N, and 9.43%. Meanwhile, in the line pattern, the highest yield strength, maximum load, and elongation values were 1.51 N/mm2, 62.72 N, and 3.54% and the highest yield of the two patterns was in the highest printing pattern, namely 100%. It was concluded that the larger the printing pattern, the wider the filament will be, as a, result the level of surface roughness will also be higher.

Abstract

Digital financial literacy is a critical competency for Micro, Small, and Medium Enterprises (MSMEs) in navigating the challenges of the digital economy and increasing global competition. This study developed a digital financial literacy training model that integrates active and interactive learning approaches with the utilization of digital technology to enhance financial management skills. The training program was implemented with 27 tenant owners at Teras Malioboro, employing a pre-test and post-test design to measure knowledge and skill acquisition. The findings indicate that the training model is highly effective in enhancing participants’ financial understanding and competence, achieving an average practicality score of 91.13%. The model is considered practical and easily adaptable across diverse MSME contexts due to its interactive and flexible design. Furthermore, this study emphasizes the importance of adopting modern digital tools and methodologies in financial training to address the evolving needs of MSMEs in the digital era. The results provide strategic recommendations for policymakers, educators, and business development practitioners to strengthen digital financial literacy and promote sustainable growth and competitiveness among MSMEs
