Hand Contour Recognition In Language Signs Codes Using Shape Based Hand Gestures Methods

The deaf and speech impaired are loosing of hearing ability followed by disability of developing talking skill in everyday communication.  Disability of making normal communication makes the deaf and speech impaired being difficult to be accepted by major normal community.  Communication used is gesture language, by using hand gesture communication. The weakness of this communication is that misunderstanding and limitation, it’s due to hand gesture is only understood by minor group.  To make effective communication in real time, it’s needed two ways communication that can change the code of hand gesture pattern to the texts and sounds that can be understood by other people. In this research, it’s focused on hand gesture recognition using shaped based hand algorithm where this method classifies image based on hand contour using hausdorff and Euclidian distance to determine the similarity between two hands based on the shortest range.  The result of this research is recognizing 26 letters gesture, the accuracy of this Gesture is 85%, from different human hands, taken from different session with different lighting condition and different range of camera from image.  It also can recognize 70% different hand contour.  The different of this research from other researches is the more the objects are, the less the classification of hands size is. Using this method, hands size can be minimized

SMPN 1 Rejang Lebong sends students to take part in the Indonesian Student Research Olympiad (Olimpiade Penelitian Siswa Indonesia - OPSI) organized by the Indonesian Ministry of Education, Culture, Research and Technology. However, the school experienced problems due to the lack of knowledge of students in choosing reference sources to be used both in research and writing scientific papers. The object of this community service are students who are members of the OPSI group at SMPN 1 Rejang Lebong. The training process can be completed on time and without obstacles and the students of OPSI SMPN 1 Rejang Lebong can choose reference sources for their research that will be proposed in June 2022.Keywords: Reference source, OPS

Performance Evaluation on Applied Low-Cost Multi-Sensor Technology in Air Pollution Monitoring

This research aims to discuss the application of multi-sensor network technology for the monitoring of indoor air pollution. Indoor air pollution has become a severe problem that affects public health, especially indoor parking. The indoor air pollution monitoring system will provide information about vehicle exhaust emission levels. We have improved the system to identify six parameters of the vehicles' gas emissions within a different location at once. This research aimed to measure the parameter of Carbon Monoxide (CO), Carbon Dioxide (CO2), Hydro Carbon (HC), temperature and humidity, and levels of particulates in the air (PM10). The performance of this system shows good ability to compare the results of measurements of air quality measuring professionals.  In this study, we investigated the performance of a custom-built prototype developed under the android-based application to detect air pollution levels in the parking area. Our objective was to evaluate the suitability of a low-cost multi-sensor network for monitoring air pollution in parking and the other area.  The benefit of our approach is that its time and space complexity make it valuable and efficient for real-time monitoring of air pollution. &nbsp

PENGENALAN KONTUR TANGAN PADA PENGKODEAN BAHASA ISYARAT BAGI PENDERITA TUNA RUNGU WICARA DENGAN MENGGUNAKAN METODE SHAPE BASED HAND GESTURE

Tuna rungu wicara merupakan kehilangan kemampuan mendengar yang disertai tidak mampu mengembangkan kemampuan bicaranya dalam kehidupan sehari-hari untuk melakukan komunikasi.Ketidakmampuan untuk berkomunikasi dengan normal membuat para penderita tuna rungu dan tuna wicara sulit untuk diterima dalam komunitas mayoritas normal.Sedangkan komunikasi yang digunakan adalah Sistem Isyarat Bahasa Indonesia (SIBI), dengan komunikasi isyarat menggunakan pergerakan tangan (Hand Gesture).Kelemahan jenis komunikasi ini adalah sering tejadi kesalapahaman dan keterbatasan, dikarenakan bahasa isyarat umumnya hanya dimengerti oleh kelompok minoritas. Untuk membantu melakukan komunikasi dengan efektif secara real time, maka perlu adanya alat komunikasi dua arah yang dapat digunakan untuk mengkodekan pola hand gesture menjadi teks, image dan suara supaya dapat dimengerti oleh semua orang. Dalam penelitian ini memfokuskan pada Hand Gesture Recognition menggunakan Algoritma Shape Based Hand dimana metode ini mengklasifikasikan image berdasarkan kontur tangan dengan menggunakan jarak Hausdorff dan jarak Euclidean, untuk menentukan tingkat kemiripan antara dua tangan berdasarkan jarak terpendek. Hasil dari pengujian ini dapat mengenali 26 huruf isyarat, tingkatakurasi pengenalan bahasa isyarat tangan 85%,pada image tangan orang yang berbeda, yang diambil pada sesi yang berbeda dengan kondisi pencahayan serta jarak image ke kamera. Serta dapat mengenali 70% kontur tangan yang berbeda dari sample yang diambil. Dengan menggunakan metode ini dibandingkan dengan penelitian lain, adalah semakin banyak jumlah objek (kontur tangan) yang digunakan, maka terdapat sedikit klasifikasi ukuran tangan. Sehingga dengan mengunakan metode ini ukuran tangan dapat diminimalisir, apabila menggunakan subjek yang banyak.Kata Kunci :kontur tangan, bahasa isyarat, metode shape based hand gesture, jarak Hausdorff, jarak Euclidean

Littering Activities Monitoring using Image Processing

Littering is a human behavior that become a habit since childhood. Even though there are rules that prohibit this behavior, the community still continues to do so. In order to limit this bad behavior, a device that can monitor and provide notifications is needed. In this research, a device is offered that can identify human activities in real time using webcam-based image processing. Then, it is processed by machine learning using the Recurrent Neural Network (RNN). The monitoring device produced in this research works by comparing the captured image data with a dataset. The captured image data will then be extracted features and form several coordinate points on the human body, then the system will classify these human activities into the category of normal activities or littering activities. This device will provide an output in the form of a warning every time the activity of littering is detected. &nbsp

AbstractThis research aimed to acknowledge the affect of scientific approach to students' study outcomes and anxiety while studying about matrix in eleventh grade of SMK PGRI Pontianak. The research method used was pre-experimental design, specifically oneshot study. The samples of this research were eleventh grader students in the major of Motor Cycle Technique, chosen by applying purposive sampling technique. Data collected by using study outcomes test and anxiety questionnaire. The data was analyzed by using SPSS 25.0 program for Windows. The analysis of pretest outcomes before scientific approach applied showed that 30% of total students were passed, while the rest were not. After scientific approach applied, the data showed that 85% of total students were passed, the rest were not. Based on the anxiety questionnaire, it showed that 10% felt anxious, 40% felt a bit anxious, 50% not felt any anxiety. Also, there were negative correlation between the students' anxiety and study outcomes, with the correlation score of -0.445.Keywords: Anxiety, Scientific Approach, Study Outcomes

The Effects of Monetary Variables on the Growth of Small and Medium Industry in Aceh Province

This study aims to analyze the effect of inflation, bank credit, and SMI investment on the growth of small and medium industries in Aceh Province. This study uses panel data consisting of 23 districts/cities in Aceh Province during the period 2014 to 2020. The analysis model used in this study is a panel data regression model. The results found in this study are variables that have a significant effect on the growth of SMIs in Aceh Province are inflation and investment in SMIs. Meanwhile, the banking credit variable has not had a statistically significant effect on the growth of SMIs. The inflation variable has a negative and significant effect on the growth of SMIs so that uncontrolled inflation will have a negative impact on the growth of SMIs. Meanwhile, SMI investment has a positive and significant impact on the growth of SMIs so that various targeted investment policies are needed so that they can support the development of SMIs in Aceh Province
