Pengembangan E-LKPD Berbasis Webtoon dengan Model Problem Based Learning (PBL) pada Materi Sistem Persamaan Linear Tiga Variabel (SPLTV)

Abstract

Abstrak: Penelitian ini bertujuan menghasilkan bahan ajar berupa E-LKPD berbasis Webtoon dengan model Problem Based Learning (PBL) pada materi Sistem Persamaan Linear Tiga Variabel (SPLTV). Metode yang digunakan adalah Research dan Development (R&D) dengan model ADDIE yang meliputi analisis, desain, pengembangan, implementasi, dan evaluasi. Subjek penelitian adalah peserta didik kelas X  PPLG 2 SMK Negeri 10 Pandeglang. Instrumen penelitian berupa angket kevalidan dan kepraktisan berdasarkan respons peserta didik. E-LKPD yang dikembangkan divalidasi oleh ahli media, ahli materi, dan ahli bahasa. Hasil validasi menunjukkan bahwa ahli media memberikan penilaian sebesar 100% (sangat valid), ahli materi sebesar 100% (valid), dan ahli bahasa sebesar 83,33% (sangat valid). Secara keseluruhan, persentase validasi adalah 94,44% dengan kategori sangat valid, sehingga E-LKPD layak diujicobakan setelah revisi sesuai masukan validator. Uji coba terbatas dilakukan pada kelompok kecil dengan rata-rata persentase 84,3% (sangat praktis), kemudian pada kelompok besar dengan rata-rata 78,6% (sangat praktis). Berdasarkan hasil validasi para ahli dan respons peserta didik, dapat disimpulkan bahwa E-LKPD berbasis webtoon dengan model PBL memenuhi kriteria sangat valid dan sangat praktis. Dengan demikian, E-LKPD ini layak digunakan sebagai bahan ajar digital serta dapat disebarluaskan untuk mendukung proses pembelajaran matematika di kelas.

Abstract: This study aims to produce a teaching material in the form of an Electronic Student Worksheet (E-LKPD) based on Webtoon with a Problem Based Learning (PBL) model on the topic of Three-Variable Linear Equation System (SPLTV). The research method employed was Research and Development (R&D) using the ADDIE development model, which consists of analysis, design, development, implementation, and evaluation. The research subjects were tenth-grade students of SMK Negeri 10 Pandeglang. The research instruments included validity and practicality questionnaires based on student responses. The developed E-LKPD was validated by media experts, material experts, and language experts. The validation results indicated that the media expert gave a score of 100% (very valid), the material expert gave 100% (valid), and the language expert gave 83.33% (very valid). Overall, the validation result reached 94.44%, categorized as very valid, which means the E-LKPD was feasible to be tested after revisions based on experts’ suggestions. A limited trial was conducted through a small group test, obtaining an average score of 84.3% (very practical), followed by a large group test with an average of 78.6% (very practical). Based on the validation results from experts and student responses, it can be concluded that the Webtoon-based E-LKPD with the PBL model meets the criteria of being very valid and very practical. Therefore, the E-LKPD is feasible to be used as digital teaching material and can be disseminated to support mathematics learning activities in the classroom.
