      Abstract
      Internet menjadi salah satu media yang digunakan ilustrator untuk menunjukkan karya mereka. Sayangnya, ini juga mempermudah pencurian karya (art theft). Untuk menandakan siapa pemilik karya suatu ilustrasi, cara yang bisa digunakan adalah dengan memberikan watermark pada ilustrasi. Akan tetapi, pemberian watermark dapat mengganggu estetika ilustrasi jika minim detail, serta watermark tersebut bisa dirusak. Salah satu metode watermarking yang dapat digunakan adalah gabungan Discrete Wavelet Transform (DWT) dan Singular Value Decomposition (SVD). Penelitian ini akan mencari cara penerapan watermark DWT-SVD untuk ilustrasi warna polos yang minim detail, keterlihatannya, dan ketahanannya. Hasilnya, metode DWT-SVD memiliki keterlihatan yang minim dan tahan terhadap sebagian jenis serangan yang umum digunakan dalam art theft di internet. Penelitian ini juga membentuk prototipe aplikasi web pemberi watermark DWT-SVD dengan HTML, CSS, dan Flask. Prototipe dapat menunjukkan pemilik ilustrasi yang benar pada ilustrasi yang tahan terhadap serangan. Metode DWT-SVD yang digunakan masih dapat ditingkatkan agar lebih tahan serangan.
       
      Internet has become one of the mediums used to show illustrators’ works and unfortunately, also makes art theft easier to do. To mark the illustrator of said artwork, illustrators can embed a watermark to the illustration. However, watermark embedding could disrupt an illustration’s aesthetics with minimum detail and the watermark could be broken. One of the possible methods used to watermark is the hybrid Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) method. This research aims to see how DWT-SVD watermark is embedded to minimally detailed flat color illustrations, the imperceptibility, and the robustness. DWT-SVD has good imperceptibility and robustness to some common attacks in internet art theft. This research also creates an application web prototype to apply the DWT-SVD watermark with HTML, CSS, and Flask. It is able to show the correct illustrator on illustrations that are robust to said attack. The robustness of the used DWT-SVD method could still be improved.
