Penelitian bertujuan untuk mendapatkan informasi tentang efektivitas media pembelajaran berbasis web menggunakan Google Sites pada mata pelajaran KJD, dan peningkatan hasil belajar elemen perencanaan dan pengalamatan jaringan kelas XI TKJT. Penelitian ini dilakukan melalui dokumentasi, observasi dan test hasil belajar. Subjek penelitannya semua siswa kelas XI TKJT yang berjumlah 32 orang. PTK dilakukan dalam 2 siklus melalui perencanaan, pelaksanaan, observasi, dan refleksi. Hasil penelitian menunjukkan Google Sites meningkatkan aktivitas belajar. Indikator kehadiran dan pengerjaan tugas pra siklus 72% menjadi 83% siklus I selanjutnya 89% siklus II. Indikator pengerjaan tugas pra siklus 61% menjadi 72% siklus I selanjutnya 83% siklus II. Nilai rata-rata kondisi awal 67,42 naik menjadi 74,11 pada siklus I dan 78,86 pada siklus II. Peningkatan siklus awal ke siklus II 11,44 point. Siswa tuntas pada kondisi awal 21 orang dengan persentase 58% naik menjadi 25 orang dengan persentase 69% pada siklus I dan 28 orang dengan perserntase 78% pada siklus II. Ketuntasan belajar siklus awal ke siklus II naik 19,44%. Data diolah menggunakan ketuntasan belajar siswa secara individual, skor rata-rata dan persentase ketuntasan klasikal.Kata kunci : Goole Sites, Perencanaan dan Pengalamatan Jaringan This Classroom Action Research (PTK) was carried out at SMKN 5 Padang, with the background that interactive learning media was not yet available even though the school had internet access.
