Abstract

The demand for cayenne pepper in Indonesia tends to increase annually, but the productivity of cayenne pepper continues to decline and depends on the changing seasons. One of the factors that must be considered in the harvest of cayenne pepper is the level of maturity. This research aims to classify the maturity level of cayenne pepper using the extraction of color and texture features. The extraction of features based on the color is taken from the mean saturation value, while the extraction of feature-based textures uses the value of the Gray Level Co-Occurrence Matrix (GLCM) feature ASM (Angular Second Moment), contrast, IDM (Inverse Difference (Entropy) and correlation (Correlation) then using angles of 0 ° and 45 °. These features become input in the classification process using the Backpropagation method. The results of the system training are able to classify the level of maturity of cayenne pepper with an accuracy of 81.4% and an accuracy of the testing process of 74.2%.

Abstract

Acute Respiratory Infection (ARI) is an infectious disease. One of the performance indicators of infectious disease control and handling programs is disease discovery. However, the problem that often occurs is the limited number of medical analysts, the number of patients, and the experience of medical analysts in identifying bacterial processes so that the examination is relatively longer. Based on these problems, an automatic and accurate classification system of bacteria that causes Acute Respiratory Infection (ARI) was created. The research process is preprocessing images (color conversion and contrast stretching), segmentation, feature extraction, and KNN classification. The parameters used are bacterial count, area, perimeter, and shape factor. The best training data and test data comparison is 90%: 10% of 480 data. The KNN classification method is very good for classifying bacteria. The highest level of accuracy is 91.67%, precision is 92.4%, and recall is 91.7% with three variations of K values, namely K = 3, K = 5, and K = 7.

Abstract

Pitaya is another name for dragon fruit which is currently a popular fruit, especially in Indonesia. One of the problems related to determining the quality of dragon fruit is the postharvest sorting and grading process. In general, farmers determine the grading system by measuring the weight or just looking at the size of the fruit, of course, this raises differences in grading perceptions so that it is not by SNI. This research is a development of previous research, but we changed the type of dragon fruit from white dragon fruit (Hylocereus undatus) to red dragon fruit (Hylocereus costaricensis). We also adapted the image processing and classification methods in previous studies and then compared them with other classification methods. The number of images in the training data is 216, and the number of images in the testing data is 75. The comparison of the accuracy of the three classification methods is 84% for the KNN method, 85.33% for the Naive Bayes method, and 86.67% for the Backpropagation method. So that the backpropagation method is the best classification method in classifying the quality grading of red dragon fruit. The network architecture used is 4, 8, 3 with a learning rate of 0.3 so that the training accuracy is 98.61% and the testing accuracy is 86.67%.

Abstract

Sweet potato is a source of carbohydrates which is an alternative food in order to accelerate food diversification. This is due to the high productivity of sweet potato so it is very profitable to cultivate. Sweet potato has many varieties, one of the differences is observed based on leaf shape which has four kinds of leaf shape, namely cordate, lobed, triangular and almost divided. The problem that often occurs is that many varieties have similarities, causing difficulties in distinguishing sweet potato varieties, especially for novice farmers. To overcome this problem, the researchers created a digital encyclopedia of sweet potato varieties based on leaf shape using computer vision. The parameters used are area, perimeter, metric, length, diameter, ASM, IDM, entropy, contrast and correlation at angles of 0 °, 45 °, 90 ° and 135 °. The amount of data used is 256 training data and 40 testing data. The K-Nearest Neighbor method is able to classify sweet potato leaf images for digital encyclopedias with an accuracy of 95% with variations in the values of K = 23 and K = 25.

Abstract

AbstrakTomat (Lycopersicum esculentum Mill.) merupakan satu komoditas unggulan pertanian karena penjualan jangka panjangnya baik. Menurunnya jumlah produktivitas dan mutu tomat disebabkan oleh curah hujan yang tinggi, cuaca dan budidaya yang tidak baik sehingga buah tomat menjadi busuk, retak, dan timbul bercak. Penyuluhan terkait peningkatan mutu tomat dinilai kurang efektif sehingga dibutuhkan sebuah sistem identifikasi kerusakan mutu buah tomat yang mampu memberikan edukasi kepada petani. Penelitian ini adalah pengembangan penelitian sebelumnya, untuk mendapatkan citra segmentasi dan ekstraksi fitur digunakan penggunaan contrast stretching dan deteksi tepi sobel. Namun kedua teknik tersebut diganti penggunaan operasi citra negatif. Didapatkan fitur yang optimal adalah gabungan fitur morfologi dan pada masing-masing sudut berdasarkan seleksi fitur. Persentasi akurasi metode KNN pada pelatihan sebesar 86.6% sedangkan akurasi pengujiannya sebesar 70%.Kata kunci: kerusakan mutu, tomat, seleksi fitur, K-Nearest NeighborAbstractTomato (Lycopersicum esculentum Mill.) is one of the leading agricultural commodities because of its good long-term sales. The decrease in the amount of productivity and quality of tomatoes is caused by high rainfall, bad weather and cultivation so that the tomatoes become rotten, cracked, and have spots. Counseling related to improving the quality of tomatoes is considered ineffective so that a system for identifying damage to the quality of tomatoes is needed that is able to provide education to farmers. This study is a development of previous research, to obtain segmented images and feature extraction using contrast stretching and sobel edge detection. However, both techniques were replaced by using negative image operations. The optimal feature is a combination of morphological features and correlations at each angle based on feature selection. The percentage of accuracy of the KNN method in training is 87%, while the accuracy in the testing is 70%.Keywords: quality damage, tomato, feature selection, K-Nearest Neighbo

Abstract

According to data from BPS Kabupaten Jember, the amount of cucumber production fluctuated from 2013 to 2017. Some literature also mentions that one of the causes of the amount of cucumber production is disease attacks on these plants. Most of the cucumber plant diseases found in the leaf area such as downy mildew and powdery mildew which are both caused by fungi (fungal diseases). So far, farmers check cucumber plant diseases manually, so there is a lack of accuracy in determining cucumber plant diseases. To help farmers, a computer vision system that is able to identify cucumber diseases automatically will have an impact on the speed and accuracy of handling cucumber plant diseases. This research used 90 training data consisting of 30 healthy leaf data, 30 powdery mildew leaf data and 30 downy mildew leaf data. while for the test data as many as 30 data consisting of 10 data in each class. To get suitable parameters, a feature selection process is carried out on color features and texture features so that suitable parameters are obtained, namely: red color features, texture features consisting of contrast, Inverse Different Moment (IDM) and correlation. The K-Nearest Neighbor classification method is able to classify diseases on cucumber leaves (Cucumis sativa L.) with a training accuracy of 90% and a test accuracy of 76.67% using a variation of the value of K = 7.
