ABSTRAK – Proses deteksi tepian pada material aluminum 1100 hasil pengelasan tungstent inert gas (TIG) telah berhasil dikembangkan, kesulitan dalam proses deteksi tepi yang dikarenakan banyaknya pengotor dalam bentuk guratan vertikal pada weld metal bisa diatasi dengan menggunakan beberapa metode. Dari sekian metode yang digunakan double thresholding dan hysterisis memiliki peran dan kontribusi paling utama dalam proses pembersihan pengotor. Proses hough transform memerlukan pengaturan jumlah garis pertemuan untuk mendapatkan dua garis dengan nilai rho = (229, 146) dan theta = (1.582496, 1.553343). Metode 4 menjadi metode paling singkat pra-prosesnya hingga deteksi garis yaitu GS > Gauss > Sobel > DT > Hys > HT. Pada pengembangan selanjutnya pengembangan interface yang memudahkan untuk memvariasikan nilai threshold dan jumlah garis pertemuan kemudian proses kalibrasi skala pixel/mm atau pixel/cm perlu dilakukan.
