Abstract

The Indonesian sign language system (SIBI) is the authorized sign system in Indonesia that the deaf society uses to convey in Indonesian. However, its use still needs to be expanded and more widespread in the community, causing difficulties in communication for hard-of-hearing people. The product of deep learning technologies such as faster region-based convolutional neural network (Faster R-CNN) in object recognition has the potential to help improve communication between deaf people and the general public. This research will implement the Faster R-CNN algorithm with three different residual network (ResNet) architectures (50, 101, and 152) for SIBI recognition. The comparison of the faster R-CNN algorithm with different architectures is also conducted to identify the best architecture for SIBI recognition, and the results are evaluated using accuracy, precision, recall, and F1-score metrics from confusion matrix calculation and execution time. Faster R-CNN model with ResNet-50 architecture showed the best and most efficient performance with accuracy, recall, precision, and F1-score metrics of 96.15%, 95%, 93%, and 94%, respectively, and an execution time of 36.84 seconds in the testing process compared to models with ResNet-101 and ResNet-152 architectures.

Abstract

Facial recognition research has its challenges due to faces complexity, ranging from facial expressions and certain conditions that make facial recognition an exciting research experiment. Moreover, many-oriented applications of machine learning have moved to devices edge, and-based facial recognition is no exception mobile. Seeing the ongoing development of facial pattern recognition algorithms such as Viola Jones, Backpropagation, this research uses the MobileFaceNet  mobile CNN model which is currently popular to be implemented in the mobile-based facial recognition presence application at the Information and Computer Engineering Education (PTIK) FKIP UNS. The deep learning method is a method for understanding and classifying objects. In the developed application, a face is captured in an image. This research uses the help of the flutter framework and the Tensorflow Lite library to develop a presence application mobile facial recognition in real-time. This paper aims to determine the value of the memorization and generalization algorithms model of CNN MobileFaceNet  on the application.  A trial of the system has been carried out by involving 30 volunteers in the testing from 2016-2019 PTIK students by random sampling. Each test was carried out for 10 iterations. From the test results, the system memorization value is 84.5%. On the other hand, the generalization results get 70% in recognizing identical but not similar images correctly. In terms of memorization and generalization, these results are better than similar studies using backpropagation

Abstract

This study aims to determine the differences in student learning outcomes in the application of blended learning the flipped classroom model to the direct learning model and also to determine the more effective learning model between blended learning type flipped classroom with direct learning model. This study uses a quantitative approach with a  quasi-experimental design and uses a pretest-posttest control. The population of this research is all students of class X majoring in Multimedia. The sample used is 54 students. The sampling technique in this research is using the total sampling method. Data obtained from the results of pre-test and post-test based on indicators of student learning outcomes.The results obtained from this study are as follows. First, there are differences in learning outcomes in Basic Graphic Design subjects in the experimental class by applying the blended learning type flipped classroom and the control class applying the direct learning model. It is proven by the average learning outcomes of the experimental class of 77.-3 and the control class of 73.14. The second is that the blended learning model of the flipped classroom type is more effective than the direct learning model. The results of the effectiveness behavior in the experimental class with the application of the flipped classroom blended learning model are in the medium category, while the control class with the direct learning model is in the low category.

Abstract

Every institution including schools has the responsibility to manage archives, especially letters. But the conventional methods of mail management take up a lot of time and space with the risk of losing documents. With a mail management information system, it can simplify and speed up mail management and minimize the risk of losing documents. This application use Yii2 framework and MySQL for the database. Rapid Application Development used in this research and 5 of 8 aspect ISO 25010 for the evaluation. With good results on all evaluation aspects this application can be used in a school environment.
