Abstract

Perhitungan sel darah putih terkait dengan sistem kekebalan tubuh manusia karena bisa memberikan informasi tentang kondisi tubuh manusia seperti diagnosis penyakit, salah satunya leukimia. Penyakit ini ditandai dengan produksi sel darah putih berlebih yang menyebabkan fungsi normal darah menjadi terganggu dan dapat menyebabkan kematian. Untuk itu diperlukan deteksi dini penyakit ini, yang salah satunya dengan menganalisis populasi atau menghitung jumlah sel darah putih pada citra mikroskopis sel darah. Perlu dilakukan metode segmentasi yang tepat agar hasil perhitungan sel dapat maksimal. Metode Watershed merupakan metode yang dapat memisahkan objek yang saling berhimpit, tetapi memiliki kelemahan jika dalam suatu citra terdapat noise atau distribusi intensitas yang tidak merata. Oleh karena itu, untuk mengatasi masalah tersebut, maka ditambahkan operasi morfologi di awal untuk mengatasi adanya obyek yang tidak termasuk sel darah putih. Tahap terakhir adalah menghitung sel darah putih menggunakan standar objek yang dianggap sel darah putih normal berdasarkan ukuran roundness obyek. Pengujian dilakukan dengan menggunakan 35 citra dengan menggunakan nilai SE = 20 pada operasi morfologi opening. Hasilnya, akurasi perhitungan jumlah sel antara sistem dengan manual (ground truth) sebesar 97.67%.

Abstract

Breast cancer is one of the highest causes of death among women, this disease ranks second cause of death after lung cancer. According to the world health organization, 1 million women get a diagnosis of breast cancer every year and half of them die, in general this is due to early treatment and slow treatment resulting in new cancers being detected after entering the final stage. In the field of health and medicine, machine learning-based classification has been carried out to help doctors and health professionals in classifying the types of cancer, to determine which treatment measures should be performed. In this study breast cancer classification will be carried out using the Naive Bayes algorithm to group the types of cancer. The dataset used is from the Wisconsin breast cancer database. The results of this study are the ability of the Naive Bayes algorithm for the classification of breast cancer produces a good value, where the average percentage of correctly classified data reaches 96.9% and the average percentage of data is classified as incorrect only 3.1%. While the level of effectiveness of classification with naive bayes is high, where the average value of precision and recall is around 0.96. The highest precision and recall values are when the test data uses a percentage split of 40% with the respective values reaching 0.974 and 0.973.
