This study aims to determine the best distance to install a CCTV camera in identifying a person's face in the passenger inspection area at the airport, which can be developed for suspect detection systems. The training data used is in the form of an image with five different angles per person, while the testing data is in the form of video. The initial stage conducted is face detection based on local features (a pair of eyes, nose, and mouth) in the input data using the Viola-Jones method. The face detection results process with pre-processing, feature extraction, and classification. In the pre-processing stage, the Brightness Enhancement (BE), Grayscale and Contrast Limited Adaptive Histogram Equalization (CLAHE) methods are used to improve the quality of the detected face. Furthermore, the feature extraction and classification stages use the Histogram of Oriented Gradient (HOG) and the Multi-class Support Vector Machine (MSVM) methods, respectively. The result shows that the best accuracy obtained is 86.76% for a CCTV camera distance of 300 cm and a height of 250 cm.

Bisindo or Bahasa Isyarat Indonesia is one of sign language methods in Indonesia, besides SIBI or Sistem Isyarat Bahasa Indonesia. Generally, Bisindo is used by deaf people in their daily communication. Deaf people tend to have barriers to communicate with others. Yet, in the educational realm, some of them still have high spirit to continue their education until university. So, they must improve their abilities or competences in communicating with others and try to get information from around the world, for example using sophisticated technology with sign language. Information system of sign language learning is important to help deaf and heard people who want to understand the deaf conversation meaning. Bisindo information system is in website form that is built by PHP, MySQL, and sublime text 3. Based on the black box method, the Bisindo information system can run well. The results of the trial to the user describe that the maximum percentage for each level of testing is above 50% except for testing of conformity with the needs of deaf only at maximum of 42%. The Bisindo information system still has weakness, but it already gives benefits especially for deaf people in Indonesia.

IOP Conference Series: Materials Science and engineering 2018年第1期336卷

作者： Lipur Sugiyanta Moch. Sukardjo Study Program of Education for Informatics and Computer Engineering/Faculty of Engineering State University of Jakarta

The 2013 curriculum requires teachers to be more productive, creative, and innovative in encouraging students to be more independent by strengthening attitudes, skills and knowledge. Teachers are given the options to create lesson plan according to the environment and conditions of their students. At the junior level, Core Competence (KI) and Basic Competence (KD) have been completely designed. In addition, there had already guidebooks, both for teacher manuals (Master's Books) and for learners (Student Books). The lesson plan and guidebooks which already exist are intended only for learning in the classroom/in-school. Many alternative classrooms and alternatives learning models opened up using educational technology. The advance of educational technology opened opportunity for combination of class interaction using mobile learning applications. Mobile learning has rapidly evolved in education for the last ten years and many initiatives have been conducted worldwide. However, few of these efforts have produced any lasting outcomes. It is evident that mobile education applications are complex and hence, will not become sustainable. Long-term sustainability remains a risk. Long-term sustainability usually was resulted from continuous adaptation to changing conditions [4]. Frameworks are therefore required to avoid sustainability pitfalls. The implementation should start from simple environment then gradually become complex through adaptation steps. Therefore, our paper developed the framework of mobile learning (m-learning) adaptation for grade 7th (junior high school). The environment setup was blended mobile learning (not full mobile learning) and emphasize on Algebra. The research is done by R&D method (research and development). Results of the framework includes requirements and adaptation steps. The adjusted m-learning framework is designed to be a guidance for teachers to adopt m-learning to support blended learning environments. During mock-up prototype, the ad
