Abstract

Pempek merupakan makanan khas Palembang yang terbuat dari campuran ikan giling, tepung, dan bumbu-bumbu penambah cita rasa dan dibuat dengan berbagai bentuk. Perbandingan karakteristik yang terdapat pada pempek selain dapat diketahui oleh orang awam melalui rasa dan tekstur kekenyalan pempek dapat juga diketahui dengan menggunakan teknologi seperti media kecerdasan buatan. Ada 4 jenis perbandingan yang ada pada pempek diantaranya adalah 1 ikan 1 tepung, 1,5 ikan 1 tepung, 2 ikan 1 tepung, dan 1 ikan 2 tepung, dengan resolusi kamera 2MP dan jarak pengambilan citra ±15cm. penelitian ini bertujuan untuk mengimplementasikan suatu sistem yang mampu mengidentifikasi kadar ikan pada pempek, dengan menerapkan Local Binary Pattern (LBP) sebagai ekstraksi fitur dan metode Jaringan Syaraf Tiruan (JST). Hasil dari ekstraksi LBP dijadikan masukan pada proses pembelajaran pada JST dengan training function traingdx serta menggunakan 40 neuron. Berdasarkan hasil pengujian menggunakan ekstraksi fitur LBP memperoleh tingkat akurasi sebesar 31,67% dan jumlah pengenalan data uji sebanyak 76 dari 240 data uji.

Abstract

Aquascape consists of complex elements, hardscape, and softscape. Aquascape requires regular maintenance, one of which is maintaining the water quality so that the plants and living things in it can thrive and the aquascape remains pleasing to the eye. We can maintain water quality by maintaining the turbidity level and water temperature. By maintaining the turbidity of the water temperature, plants and living things in the aquascape will continue to thrive. To keep the water conditions clear and healthy, a system is needed to control the turbidity level and temperature of the aquascape water. This study builds a system that can maintain water quality in an Internet of Things-based aquascape by implementing the Fuzzy Mamdani algorithm to optimize a system that can adjust the fan speed to lower the water temperature and determine how long the water pump will run and flow. Water in the aquascape. The results of the tool test are obtained; if the temperature, pH, and water turbidity sensor values ​​are close to the normal water limits, the water pump will turn on. If the temperature is above 27.89ºC and the pH is above 13, the fan will run at full speed. To measure the accuracy of this aquascape system, MAPE is used with an error value of 3% for the fan data generated.

Abstract

Wood is the part of the stem or twig of a plant that hardens as a result of the natural lignification process. Wood has properties that cannot be imitated by other materials. The properties of wood are durable, strong and non-corrosive. Weaknesses of wood, namely natural deficiencies contained in it such as knot defects, heart brittle defects, and borer hole defects. This study uses the SVM (Support Vector Machine) method to obtain accuracy against defects in wood by using GLCM (Gray Level Co-occurence Matrix) extraction. The dataset used contains 160 images and then separated into 112 train data and 48 test data. The identification carried out on the Gaussian kernel got the highest accuracy of 27.08% compared to using the Linear kernel with a smaller accuracy of 16.67%.

Abstract

Diseases on palm leaves are diseases caused by bacteria or fungi. One way to find out diseases on palm leaves is to observe the pattern on the surface of the palm leaves. The pattern on the palm leaves will be analyzed by an expert to find out whether there is disease on the palm leaves or not. This study aims to classify oil palm leaves whether there is disease or not on oil palm leaves by using a program. The right method is needed to produce good accuracy, the researcher uses the ANN (Artificial Neural Network) classification method and the LBP (Local Binary Pattern) extraction method. The steps carried out on the image before being classified are Grayscale, then extraction using LBP (Local Binary Pattern) and classification using ANN (Artificial Neural Network) using 17 train functions with the result that 5 neurons get an average accuracy of 81%, precision 95 %, and 94% recall. In 10 neurons get an average of 95% accuracy, 97% precision, and 96% recall. And the 20 neurons get an average of 97% accuracy, 97% precision, and 96% recall.

Abstract

Currently, there are many online stores or marketplaces either owned by individuals / companies that are specifically eduated by buyers or costumers who want to see and buy products. In some countries in the world, the marketplace functioned as electronic commerce is often interpreted as e-commerce in several locations in Indonesia. The difference between marketplace and e-commerce is in a concept similar to the traditional market / store. In this study used the C4.5 Algorithm method to analyze the quality of service satisfaction and products from online stores perfume chantik. Using the C4.5 algorithm method, it is necessary to know the accuracy of predictions, namely the ability of models to be able to predict class labels against new data or previously unknown data well. In this study, experiments were conducted using the C4.5 algorithm's data mining deceision tree classification method against customer satisfaction kuisoner data after buying from an online store parfume chantik.

Abstract

Learning outcomes are focused on what students want to be able to do during or at the end of a learning process that includes the learning and teaching process. The problem when learning online is that there are network constraints and the lack of teaching hours for teachers and the limited amount of material that can be delivered. So a solution is needed to determine the level of student satisfaction in the process of achieving online learning in schools. This study applies the C4.5 algorithm for the classification of online learning outcomes at MAN 3 Blitar. This study aims to predict the achievement of online learning with the C4.5 algorithm. There are 10 attributes that affect the achievement of online learning, namely: remembering, attendance, assignments, assessment, material, conditions, application, creating, discussion, analysis. With research, it can make it easier for teachers to determine online learning methods with minimal constraints. The results of the research using the C4.5 algorithm are 27 decision trees and rules, the highest gain value is the Create attribute, which is 0.383923. The results of the validation test using the confusion matrix level of accuracy in predicting online learning achievement on average are 88%, precision is 83%, recall is 86%. With the results of the accuracy value obtained, it can be said to be included in the Good Classification.

Abstract

Pandemic Covid-19 in Indonesia has caused face-to-face learning to be temporarily suspended, resulting in online learning. Indirectly encouraging an E-Learning application to have a high usage rate and number of downloads on the Play Store. The best application is always given to the application with highest number of downloads and ratings on the Play Store. Meanwhile comments from users need to be taken into account because many E-learning applications have the same number of downloads and ratings Moodle and Edmodo, therefore a sentiment analysis of the popularity of Moodle and Edmodo is carried out using the SVM Algorithm. User comments on Play Store are used as data source. From 250 data scraping results from user comments, the preprocessing process and TF IDF extraction were carried out. Based on results of testing using confusion matrix it can be concluded that user sentiment the Edmodo application has a better percentage compared to the Moodle application which can be shown by the emergence of a positive sentiment 67% with accuracy 84% and precision 93%, recall 82% and f1-score 87%. Moodle application has a negative sentiment percentage 67% with an accuracy 82% and a precision test of 79%, 100% recall and 88% f1-score.

Abstract

This research analyzed 176 Palembang public universities’ students’ theses which were published in 2020. The data was analyzed by conducting text processing and extraction with TF-IDF feature by using two scenarios, the reduced feature value and the unreduced one, with SVD method. In each scenario, three metrics, cosine, euclidean, and, manhattan were used, which generated six scenarios in total. The result found that the best quality of cluster which was measured by silhouette coefficient comes from metric cosine and reducted by SVD with the silhouette coefficient value of 0.88382763, intracluster value of 0.08688583, and intercluster value of 0.74671096. Therefore, the cluster quality value of the reducted feature is the best among all metrics. In addition, the use of DBSCAN method showed a positive correlation between epsilon and intracluster with the value of 0.97669, and also showed a negative correlation between epsilon and silhouette with the value of 0.9789.
