Abstract

Driving is one of the human activities in which daily life is often done. Driving can be done by land, air, and sea. Human mobility in driving is very high on land routes using various means of transportation. For the sake of smooth driving, roads are often equipped with traffic signs in each traffic area. Traffic signs are a means for road users to provide information and guidance for motorists about the situation in the surrounding area. The number of motorists who lack awareness of the knowledge of reading traffic signs is one of the biggest causes of accidents in Indonesia. So that a system is needed that can help in recognizing traffic signs, especially prohibited signs. The system designed using Haar Wavelet feature extraction and Euclidean distance as a classification. From the data that has been tested, the level of recognition in reading traffic signs is prohibited by 92%.

Abstract

Quadcopter merupakan salah satu jenis perangkat terbang tanpa awak yang menggunakan 4 motor yang masing-masing dilengkapi dengan propeller yang berfungsi sebagai alat untuk terbang dan bermanuver. Kestabilan terbang quadqopter dipengaruhi oleh kemampuan kendali dalam mempertahankan derajat kemiringan. Nilai derajat kemiringan didapatkan dari sensor IMU (inertial measurement Unit).PID (Propotional,Integral and Derivative) merupakan kendali yang dapat meminalisasi error yang disebabkan ketidaksesuaian derajat kemiringan yang ditetapkan (set value) dan derajat kemiringan ketika quadcopter terbang (present value). Nilai kp, ki, dan kd didapatkan dengan mencoba beberapa kombinasi Nilai kp, ki, dan kd serta memperhatikan pergerakan quadqopter (try and error).Pengujian kestabilan dilakukan dengan menguji pada masing-masing sumbu quadcopter (roll-pitch). Berdasarkan pengujian yang dilakukan, quadqopter dapat bergerak berdasarkan derajat kemiringang yang telah ditentukan (0 dan 30 derajat kemiringan). Berdasarkan pengujian kestabilan masing- masing sumbu yang telah dilakukan, derajat kemiringan quadqopter masih berflutuasi hingga dengan simpangan terbesar hingga 12 derajat.

Abstract

Communication is essential in conveying information from one individual to another. However, not all individuals in the world can communicate verbally. According to WHO, deafness is a hearing loss that affects 466 million people globally, and 34 million are children. So it is necessary to have a non-verbal language learning method for someone who has hearing problems. The purpose of this study is to build a system that can identify non-verbal language so that it can be easily understood in real-time. A high success rate in the system needs a proper method to be applied in the system, such as machine learning supported by wavelet feature extraction and different classification methods in image processing. Machine learning was applied in the system because of its ability to recognize and compare the classification results in four different methods. The four classifications used to compare the hand gesture recognition from American Sign Language are the Multi-Class SVM classification, Backpropagation Neural Network Backpropagation, K - Nearest Neighbor (K-NN), and Naïve Bayes. The simulation test of the four classification methods that have been carried out obtained success rates of 99.3%, 98.28%, 97.7%, and 95.98%, respectively. So it can be concluded that the classification method using the Multi-Class SVM has the highest success rate in the introduction of American Sign Language, which reaches 99.3%. The whole system is designed and tested using MATLAB as supporting software and data processing.

Abstract

Conflicts between junior high school students cannot be underestimated or left unchecked so that it drags on and causes ongoing conflicts if a settlement pattern and root cause are not found immediately. This study aims to analyze the pattern of intergroup relation-based conflict resolution carried out by junior high school students. This article is the result of research conducted using the development (R&D) method with the stages of needs analysis, development, and testing. The data collection method was carried out by distributing questionnaires to public junior high schools randomly consisting of 799 respondents, namely 329 male and 470 female. Data processing is done by grouping student answers based on research indicators in order to obtain a conflict resolution model used by students. The results showed that the pattern of intergroup relation-based conflict resolution carried out by junior high school students and equivalent in solving problems, students were more dominant in choosing how to communicate, either through cellphones or meeting in person to discuss the root causes of the problems that occurred then reconciled by apologizing to each other, do not do violence, avoid emotions, say rude, high-pitched, to avoid fights. As for students who use violence in an effort to solve problems, it will occur if one of their friends shows opposition and resistance, has a high-pitched tone to speak harshly so that it ignites excessive emotions and causes fights.

Abstract

Jantung coroner merupakan salah satu penyakit jantung yang sangat banyak menyerang manusia. Penyebab jantung coroner adalah terjadinya penumpukan lemak dan kolestrol pada dinding pembuluh darah. Penyebab utama dari jantung coroner karena gaya hidup manusia yang kurang sehat. Pola makan tidak yang buruk, obesitas dan kurang berolahraga menjadi penyebab utama munculnya penyakit jantung coroner. Penyempitan pembuluh darah sangat berkaitan erat dengan aliran darah yang terjadi ke mata khususnya bagian iris. Sehingga diperlukannya suatu cara dengan metode yang lebih efesien dan murah untuk mengetahui dan mengidentifikasi penyakit jantung sejak diri dengan menggunakan iridologi. Sistem yang dirancang dengan menggunakan Circle Hough Tranform (CHT) sebagai deteksi bagian iris secara otomatis, Gray Level Co- occurrence Matrix (GLCM) sebagai ekstraksi ciri dan Support Vector Machine (SVM) sebagai klasifikasi. Pengujian telah dilakukan terhadap 40 data citra yang memperoleh tingkat keberhasilan identifikasi sebesar 87.5%.
