This study
aims to determine the feasibility and effectiveness of a digital book on
technical drawing using the product-based learning model to enhance students’
ability to understand and create designs in the Fashion Design and Production
subject for 11th-grade students at SMKN 1 Buduran Sidoarjo. This research is a
development study that applies the ADDIE development model, which consists of
five stages: Analyze, Design, Development, Implementation, and Evaluation. The study
was conducted at SMKN 1 Buduran Sidoarjo, with the research population
consisting of 36 students from the 11th-grade Fashion Design and Production
class. The sampling procedure in this study used the purposive sampling
technique, in which subjects were deliberately selected based on specific
objectives and considerations. Data collection procedures in this study were
carried out using two methods: (1) A pretest-posttest instrument to measure
students' ability to understand the procedure of fashion design. (2) Observation
method, aimed at obtaining data on students' ability to create designs after
undergoing the treatment. The data analysis technique used in this study was
the N-Gain test. The results of this development research indicate that the
digital book on technical drawing was validated as "highly feasible"
with a total score of 98%. The N-Gain test results show an increase in
understanding ability with a score of 0.56 and an increase in design creation
ability with a score of 0.57, which, according to Meltzer's N-Gain criteria
(2012:184), falls into the moderate category. Thus, it can be concluded that
students’ ability to understand and create designs was higher after using the
digital book compared to before using it.
