Development of a Practicum Video for Food Product Standardization in Vocational Chemistry Learning

Abstrak

This study aimed to develop a Practicum Video for Food Product Standardization in the Applied Chemistry subject at SMK SMTI Pontianak, determine its feasibility, and examine its potential to improve students' analytical ability and practical skills. The study employed a Research and Development (R&D) method using ADDIE model. The research subjects comprised nine students in the small-group trial and 30 students in the large-group trial, without the use of a control group. The research instruments consisted of expert validation sheets, pretest–posttest assessments, and students’ practical skills observation sheets. The results showed that the Practicum Video was categorized as very feasible, with material expert and media expert validation percentages of 89.84% and 97.22%, respectively. Following implementation, students demonstrated a moderate improvement in analytical ability, with N-Gain scores of 44.90% in the small-group trial and 54.65% in the large-group trial. Additionally, students' practical skills were categorized as skilled, achieving average scores of 81.24% in the small-group trial and 83.54% in the large-group trial. Therefore, the developed Practicum Video is a highly feasible learning medium that supports students' analytical ability and practical skills, though further controlled studies are needed to establish definitive effectiveness.
