[ABSTRAK
Kanker payudara adalah tumor ganas yang tumbuh akibat pertumbuhan sel-seljaringan yang tidak normal pada jaringan payudara. Kanker payudara pada wanitamerupakan penyakit yang kini paling banyak diderita dibandingkan jenis kankerlainnya. Cara yang dilakukan agar penyakit ini tidak memiliki kesempatan untukmenyebar adalah dengan mendeteksinya sedini mungkin dengan menggunakanmammografi.Pada penelitian ini penulis telah merancang suatu sistem yang menggunakankomputer untuk mendeteksi dan mengklasifikasi kanker payudara pada citramammogram. Citra mammogram yang digunakan adalah citra mammogram dariMommographic Image Analysis Society (MIAS) yang terdiri dari 322 citra.Pengolahan awal citra pada sistem ini menggunakan metode Otsu Thresholding,pendeteksian tepi dengan menggunakan metode Canny, dan metode dilasi. Ciriyang digunakan pada sistem ini adalah Gray Level Co-occurrence Matrix(GLCM) dan Discrete Wavelet Transform (DWT). Metode pengklasifikasian yangdigunakan pada penelitian ini adalah Support Vector Machine (SVM).Sistem memiliki ketahanan yang baik terhadap noise salt and pepper pada nilainoise tertentu pada tiap jenis citra mammogram yang digunakan. Tingkatkeakuratan berkisar 80% pada saat diberi noise sebesar -16dB pada citramammogram jinak dan ganas. Keakuratan sistem juga teruji cukup baik untukjumlah data latih yang hanya sebesar 70% dimana tingkat keakuratanpendeteksian dan pengklasifikasian adalah sebesar 80,6%.

ABSTRACT
Breast cancer is a malignant tumor that grows as a result of the growth of tissuecells that are not normal in the breast tissue. Breast cancer in women is a diseasethat is now the most common cancer than other types. How that is done so that thedisease does not have a chance to spread is to detect it as early as possible byusing mammography.In this study, the authors have designed a system that uses a computer to detectand classify breast cancer on a mammogram image. Mammogram image has beentaken from Mommographic Image Analysis Society (MIAS) which consists of 322images. Initial processing images on this system using Otsu Thresholding, edgedetection using Canny method, and the method of dilation. Features used in thissystem is the Gray Level Co-occurrence Matrix (GLCM) and Discrete WaveletTransform (DWT). Claassification method was used in this study is SupportVector Machine (SVM).The system has good resistance to salt and pepper noise on certain noise value foreach type of mammogram image are used. The accuracy range was 80% whengiven the noise of -16dB on mammogram images of benign and malignant. Theaccuracy of the system was also tested well enough for the amount of training datathat only 70% where the level of detection and classification accuracy is 80,6 %.;Breast cancer is a malignant tumor that grows as a result of the growth of tissuecells that are not normal in the breast tissue.
