MODUL PRAKTIKUM TERINTEGRASI QR CODE: INOVASI DIGITAL UNTUK PEMBELAJARAN VOKASI TEKNIK KIMIA INDUSTRI DI SMK

Abstract

The limited availability of practicum teaching materials integrated with digital technology remains a major obstacle in Basic Industrial Chemical Engineering learning at vocational high schools, often leaving students struggling to understand work procedures independently. This study aims to develop a QR Code-based practicum module and to measure its validity, practicality, and effectiveness in improving learning outcomes. The study applied a Research and Development (R&D) approach using the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The product was validated by three expert validators (media, instructional design, and content), trialed on a limited scale with 2 teachers and 10 students to assess practicality, and tested for effectiveness through a one-group pretest-posttest design involving 15 tenth-grade students using a Higher Order Thinking Skills (HOTS)-based instrument. Results indicate the module was valid, with an average score of 79.11% (Feasible category); highly practical, with a score of 87.81%; and effective in improving learning outcomes, with scores rising from 51.00 to 89.00 (N-Gain 0.78, High category; paired t-test t = 18.46; df = 14; p < 0.001). These findings confirm that integrating QR Code into printed modules offers a viable teaching-material solution for vocational chemical engineering education.

Keterbatasan bahan ajar praktikum yang terintegrasi dengan teknologi digital menjadi salah satu kendala utama dalam pembelajaran Dasar-Dasar Teknik Kimia Industri di SMK, sehingga peserta didik cenderung kesulitan memahami prosedur kerja secara mandiri. Penelitian ini bertujuan mengembangkan modul praktikum berbasis QR Code serta mengukur tingkat kevalidan, kepraktisan, dan keefektifannya dalam meningkatkan hasil belajar. Penelitian menggunakan pendekatan Research and Development (R&D) dengan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Produk divalidasi oleh tiga validator ahli (media, desain pembelajaran, dan materi), diujicobakan secara terbatas kepada 2 guru dan 10 murid untuk mengukur kepraktisan, serta diuji efektivitasnya melalui desain one-group pretest-posttest terhadap 15 murid Kelas X Teknik Kimia Industri menggunakan instrumen tes berbasis Higher Order Thinking Skills (HOTS). Hasil penelitian menunjukkan modul dinyatakan valid dengan rata-rata skor 79,11% (kategori Layak), sangat praktis dengan skor 87,81%, dan efektif meningkatkan hasil belajar dari rata-rata 51,00 menjadi 89,00 (N-Gain 0,78, kategori Tinggi; uji-t berpasangan t = 18,46; df = 14; p < 0,001). Temuan ini menegaskan bahwa integrasi QR Code pada modul cetak dapat menjadi solusi bahan ajar praktikum yang layak diterapkan pada pendidikan vokasi bidang kimia industri.
