Abstract

Facial feature extraction is the process of searching for features of facial components such as eyes, nose, mouth and other parts of human facial features. Facial feature extraction is essential for initializing processing techniques such as face tracking, facial expression recognition or face shape recognition. Among all facial features, eye area detection is important because of the detection and localization of the eye. The location of all other facial features can be identified. This study describes automated algorithms for feature extraction of eyes and mouth. The data takes form of video, then converted into a sequence of images through frame extraction process. From the sequence of images, feature extraction is based on the morphology of the eyes and mouth using Neural Network Backpropagation method. After feature extraction of the eye and mouth is completed, the result of the feature extraction will later be used to detect a person’s drowsiness, being useful for other research.

Abstract

Akhir-akhir ini perkembangan teknologi semakin pesat, metode interaksi dan komunikasi antara pengguna dengan komputer adalah salah satu tuntutan perkembangan teknologi. Berbagai macam pembaharuan teknologi mengusahakan untuk meminimalisir berbagai macam perangkat menjadi satu agar lebih mudah digunakan. User lebih membutuhkan peralatan komunikasi yang bersifat alami karena tidak membutuhkan kontak langsung dengan peralatan input. Misalnya dengan gerakan dari tubuh manusia didepan kamera komputer sudah bisa menginterpretasikan. Untuk mengatasi masalah tersebut maka dilakukan suatu penelitian tentang deteksi isyarat tangan. Inputan berupa isyarat dan gerakan tangan didepan kamera dapat memberikan aksi pergerakan pada mouse yang diistilahkan dengan kamera mouse. Metode yang digunakan adalah convexhull algorithm. Melalui convexhull algorithm bisa didapatkan jumlah jari tangan yang kemudian dapat dijadikan acuan dalam pengerjaan aksi mouse. Sebenarnya sudah banyak penelitian tentang camera mouse, tetapi implementasinya masih banyak yang bergantung dengan peralatan tambahan. Penelitian ini mengembangkan penelitian yang sudah ada, yaitu hand gesture recognition dengan implemen-tasi pergerakan mouse dari video secara realtime. Dengan hand gesture recognition dan menggunakan metode convexhull algorithm pengenalan tangan akan lebih mudah hanya dengan menggunakan kamera, hanya dengan hitungan detik aksi mouse pada komputer dapat berjalan dengan baik yaitu dengan tingkat akurasi sebesar 68 % dari 75 kali percobaan

Abstract

Pencemaran udara merupakan hal yang tidak dapat dihindarkan pada setiap daerah. Sumber pencemaran udara tersebut bermacam-macam, seperti gas kendaraan bermotor, limbah pabrik, dan sampah yang dibuang sembarangan. Penelitian ini mengusulkan pembuatan sebuah sistem pemantauan kualitas udara di kota Surabaya. Zat pencemar yang menjadi tolak ukur untuk menentukan tingkat pencemaran udara dalam penelitian ini adalah CO (Carbon monoxide), SO2 (Sulfur dioxide), O3 (Ozone), dan NO2 (Nitrogen dioxide). Sensor yang digunakan untuk mengetahui kadar zat pencemar tersebut adalah MQ-7 dan MQ-135. Penelitian ini memanfaatkan wireless sensor network (WSN) dan teknologi LoRa sebagai media pengiriman data. Empat titik pengujian dan dua papan ISPU (Indeks Standar Pencemar Udara) sebagai ground truth digunakan untuk mengetahui tingkat pencemaran udara di kota surabaya. Pengukuran dan perbandingan antara sensor dengan ground truth dilakukakan untuk mengetahui hasil penelitian ini. Hasil pemantauan tingkat pencemaran udara didapatkan dengan menggunakan sensor MQ-7 dan MQ-135 yang mampu membaca keadaan zat pencemar dengan tingkat error paling besar 5,77%. Sistem pengiriman data menggunakan teknologi LoRa pada jarak terjauh 2,97 km dapat mengirimkan data dengan baik dengan RSSI (Received Signal Strength Indication) -92 dBm pada ketinggian 12 mdpl dan frekuensi 433 Mhz. Data hasil pemantauan tersebut dapat dipantau melalui aplikasi ThingSpeak secara online. Everywhere, air pollution isn't avoidable. The source of pollution could be anything, such as gas emitted from vehicles, toxic waste, and garbages that are thrown not to their places. In this study, a system to monitor air quality will be built in Surabaya. The pollutants that will be the benchmark to measure the level of air pollution are CO (Carbon Dioxide), SO2 (Sulfur Dioxide), O3 (ozone), and NO2 (Nitrogen Dioxide). The sensor that will be used to detect the level of pollutants is called MQ-7 and MQ-135. This study takes Wireless Sensor Network (WSN) into use while LoRa technology is being used as a media to send data. To know the level of pollution in Surabaya, 4 test points are taken, and AQI (Air Pollution Index) are used as ground truth. After measuring and comparing the sensor and ground truth, the result that is taken using MQ-7 sensor and MQ-135 could read the status of pollutants with 5.77% as its highest sensor range. After that, the system that is sending the data using LoRa technology with 2.97 km as its highest distance could send the data well with RSSI -92dBm in 12m MSL height and 433 Mhz frequency.

Abstract

In automotive learning, teachers generally use books and teaching aids as learning media. Automotive learning outcomes show the low value of learning outcomes. Thus a learning media is needed that can help improve learning outcomes. One way to overcome this problem is to use learning media that utilize augmented reality technology. In this study, a learning media using augmented reality technology based on android was developed to simulate the brake system on four-wheeled vehicles in 3 dimensions. The Augmented Reality work system used is marker based tracking, and uses 3D Max software and the Vuforia plug-in. In terms of pedagogy, this learning system uses the Modality Principle. Participants are class XI students of SMK YPM 4 Taman. This research uses experimental research. The students involved were 44 students divided into 2 groups, with each group consisting of 22 students. Both groups received a pre-test and a post-test. The experimental group was given treatment with Augmented Reality-based learning media, while the control group did not use conventional learning media. After making comparisons, the results show less than optimal due to the pandemic period. The results showed that the pre-test result between the control group and the experimental group was 49.32, and the post-test result for the control group was 62.73, while for the experimental group it was 73.18. So that from the difference in the difference in post-test scores between the experimental group and the control group shows that the treatment factor by providing Augmented Reality-based learning media in the experimental group has an influence. From observations and interviews, students were more active in learning activities and students were eager to take part in learning. This proves that students are interested in this media which can generate motivation to learn.

Abstract

The digital image processing technique is a product of computing technology development. Medical image data processing based on a computer is a product of computing technology development that can help a doctor to diagnose and observe a patient. This study aimed to perform classification on the image of the thorax by using Convolutional Neural Network (CNN).  The data used in this study is lung thorax images that have previously been diagnosed by a doctor with two classes, namely normal and pneumonia. The amount of data is 2.200, 1.760 for training, and 440 for testing. Three stages are used in image processing, namely scaling, gray scaling, and scratching. This study used Convolutional Neural Network (CNN) method with architecture ResNet-50. In the field of object recognition, CNN is the best method because it has the advantage of being able to find its features of the object image by conducting the convolution process during training. CNN has several models or architectures; one of them is ResNet-50 or Residual Network. The selection of ResNet-50 architecture in this study aimed to reduce the loss of gradients at certain network-level depths during training because the object is a chest image of X-Ray that has a high level of visual similarity between some pathology. Moreover, several visual factors also affect the image so that to produce good accuracy requires a certain level of depth on the CNN network. Optimization during training used Adaptive Momentum (Adam) because it had a bias correction technique that provided better approximations to improve accuracy. The results of this study indicated the thorax image classification with an accuracy of 97.73%.
