Mammals have several characteristics that can be distinguished, such as footprints, voice, and face shape. Mammals can be recognized. To classify the face shape of mammals, the Histogram of Oriented Gradients (HOG) and Support Vector Machine (SVM) methods can be used. This study uses the LHI-Animal-Faces dataset which is taken as many as 15 species of mammals, where each type of mammal is selected 60 images and resized to 150x150 pixels. The image is converted into a grayscale image for the HOG feature extraction process. Furthermore, the classification process uses SVM. The kernels used are Linear, Polynomial, and Gaussian kernels. The testing process uses K-Fold Cross Validation. The folds used are 3-fold, 4-fold, 5-fold, 6-fold, and 10-fold. The performance of the HOG feature and the SVM method that gives the best results is the Linear kernel using 10-fold with an accuracy value of 96.55%, precision of 77.92%, and recall of 74.11%. The sequence of kernels that give the best results in this test is the Linear kernel, Polynomial kernel, and Gaussian kernel.

Electricity meter is a tool used to measure the electricity power consumption. Electricity meter has the numeral part known as electricity meter number which load the electricity power consumption.Usually, the recording is done once a month, by recording the number on the electric meter into the book, and then the recording officer take pictures the power meter. Electricity meter number can be analized through an image using the knowledge of pattern recognition in image processing. In analyzing picture of electicity meter number, we used Histogram Of Oriented Gradients (HOG) as the feature extraction and Supply Vector Machine (SVM) as the classification method. The result using 100 train-set and 30 test-set for each combination of category shows that the best resolution is 10 MP and 14 MP and the picture capturing distance is at 30 cm byand 10 cm by 73,33% accuracy for each image and 86,67% for each number and confusion matrix shows that presentation of all number is 75,48%. Key words:Number Recognition, Histogram Of Oriented Gradients (HOG) , Support Vector Machine (SVM)

Mammal type can be classified based on the face. Every mammal’s face has a different shape. Histogram of Oriented Gradient (HOG) used to get shape feature from mammal’s face. Before this step, Global Contrast Saliency used to make images focused on an object. This process conducts to get better shape features. Then, classification using k-Nearest Neighbor (k-NN). Euclidean and cityblock distance with k=3,5,7 and 9 used in this study. The result shows cityblock distance with k=9 better than Euclidean distance for each k. Tiger is superior to others for all distances. Sheep is bad classified.

K-Means++ and K-Medoids are data clustering methods. The data cluster speed is determined by the iteration value, the lower the iteration value, the faster the data clustering is done. Data clustering performance can be optimized to get more optimal clustering results. One algorithm that can optimize cluster speed is Genetic Algorithm (GA). The dataset used in the study is a dataset of EEG Eyestate. The optimization results before hybrid GA on K-Means++ are the iteration average values is 11.6 to 5,15, and in K-Medoid are the iteration average values decreased from 5.9 to 5.2. Based on the comparison of GA K-Means++ and GA K-Medoids iterations, it can be concluded that GA - K-Means++ better

Pepaya merupakan salah satu buah tropis yang banyak manfaat. Penentuan kualitas buah pepaya secara konvensional memiliki keterbatasan. Penelitian ini dilakukan untuk menentukan kualitas pepaya berdasarkan bentuk fisiknya. Metode yang digunakan untuk menentukan kualitas buah pepaya yaitu dengan menggunakan metode k-Nearest Neighbors (k-NN). Metode k-NN digunakan untuk melakukan klasifikasi dengan cara mencari kedekatan data uji dengan basis data yang sudah diberi label. Ciri fisik papaya dapat dilihat dari warna, ukuran dan defect. RGB merupakan salah satu fitur warna. Namun fitur warna yang digunakan yaitu fitur R (Red) dan G (Green) sedangkan untuk fitur ukuran yaitu minor axis dan major axis. Penelitian ini menggunakan jarak Euclidean dan Manhattan dengan nilai k = 3, 5, 7, dan 9. Citra buah pepaya yang digunakan dalam penelitian ini merupakan citra buah pepaya yang diambil sendiri yang terdiri dari baik, sedang, dan jelek dengan total sebanyak 150 citra yang terbagi menjadi 120 data training dan 30 data testing. Hasil terbaik yang diperoleh yaitu dengan menggunakan jarak Euclidean dan nilai k sebesar 7 dengan accuracy sebesar 86,67%, precision sebesar 87,50%, dan recall sebesar 80,00%. Nilai accuracy, precision dan recall menunjukkan perfoma penentuan kualitas yang baik.

Heart disease is a condition which heart as vital human organ is disordered and doesn’t function properly. Heart disease is one of deadliest diseases in the world and the leading cause of death globally, taking an estimated 17.9 million lives each year. In this study, heart disease patients’ data were clustered to see the characteristic and similarities of each patient. The dataset used in the study is Heart Disease Patients dataset, which consists of 303 patients’ medical data with 11 features. Clustering method used in the paper are K-Means and GA K-Means. Genetic Algorithm is used to optimized the initial centroid for K-Means clustering. The results were evaluated by noting the iteration, inter cluster, and intra cluster of each clustering method. Genetic algorithm is able to optimize the K-Means method which can be seen in iteration average, from 13,4 to 12,5 iteration with the decreasing of the maximum iteration from 21 to 17 iterations. Based on the calculation of inter cluster and intra cluster, the intra cluster results of GA K-Means tend to be better than K-Means and for inter cluster, there is a very little different result, where K-Means method inter cluster average slightly better than GA K-Means.
