Abstract

Learning media development is the study and ethical practice of facilitating learning and improving performance by creating. This study aimed to develop a learning media application for manufacturers to improve their skill of reducing costs in rice-cracker production so preventing problems of loss and poverty. This study’s research and development methodology used the ADDIE model consisting of 5 stages: 1) analysis, 2) design, 3) development, 4) implementation; and 5) evaluation. Validation of learning media was undertaken by three experts, followed by three trials. The experimental one-shot case design comprised 20 rice cracker manufacturer participants obtained voluntarily and examined their skill level after media application use. Evaluation by the media experts (82.67% and 81.33%) and the instructional design expert (86.67%) indicate that the learning media application was of excellent quality. Results from the individual trial (83.11%), small group trial (84.29%), and field trial (79.51%), showed that the learning media application was effective in improving skill of rice cracker production cost reduction. Results of the test by 20 participants- mean score-27.40/30; T-test value-19.517; and Sig.= 0.000 (2-tailed)- indicate that they had the skills to reduce their manufacturing costs. Therefore, this instructional media merits use as learning media for improving the skill of rice cracker production cost reduction.
