Perkembangan teknologi informasi mendorong pemanfaatan media pembelajaran digital untuk meningkatkan kualitas pembelajaran. Pada mata pelajaran Jaringan Komputer di SMK, siswa masih mengalami kesulitan memahami materi yang bersifat abstrak, seperti topologi jaringan, konfigurasi IP address, dan subnetting. Penelitian ini bertujuan mengembangkan media pembelajaran interaktif berbasis web serta menguji validitas, kepraktisan, dan efektivitasnya dalam meningkatkan pemahaman siswa. Penelitian menggunakan metode Research and Development (R&D) dengan model Four-D (Define, Design, Develop, dan Disseminate). Subjek
penelitian terdiri atas 30 siswa kelas X SMK Al-Muhammad Cepu. Data dikumpulkan melalui lembar validasi ahli, angket kepraktisan guru dan siswa, serta tes pretest dan posttest. Hasil penelitian menunjukkan bahwa media memperoleh skor validitas 4,44 (sangat valid), kepraktisan 100% oleh guru dan 88,4% oleh siswa (sangat praktis), serta nilai N-Gain sebesar 0,91 (kategori tinggi). Dengan demikian, media pembelajaran interaktif berbasis web dinyatakan valid, praktis, dan efektif untuk mendukung pembelajaran Jaringan Komputer di SMK.

Abstract

The rapid development of information technology has encouraged the integration of digital learning media to improve the quality of education. In Computer Networking courses at vocational high schools, students often experience difficulties understanding abstract concepts such as network topology, IP addressing, and subnetting. This study aimed to develop a web-based interactive learning media and evaluate its validity, practicality, and effectiveness in improving students' conceptual understanding. The study employed the Research and Development (R&D) method using the Four-D (4D) model, consisting of Define, Design, Develop, and Disseminate stages. The participants were 30 tenth-grade students of SMK Al-Muhammad Cepu. Data were collected through expert validation sheets, teacher and student practicality questionnaires, and pretest and posttest instruments. The results showed that the developed media achieved a validity score of 4.44 (very valid), practicality scores of 100% from the teacher and 88.4% from the students (very practical), and an N-Gain score of 0.91 (high category). Therefore, the developed web-based interactive learning media is
valid, practical, and effective for supporting Computer Networking learning in vocational high schools.
