Induction Motor in Electrical drive system at a accelleration speed for example in electric cars have a hard speed setting is set on a wide range, causing an inconvenience for motorists and a fast response is required any change of speed. It is necessary for good system performance in control motor speed and torque at low speed or fast speed response, which is operated by Indirect Field Oriented Control (IFOC). Speed control on IFOC methods should be better to improving the performance of rapid response in the induction motor. In this paper presented a method of incorporation of Fuzzy Logic Controller and Backstepping (Fuzzy-Backstepping) to improve the dynamically response speed and torque in Induction Motor on electric car, so we get smoothness at any speed change and braking as well as maximum torque of induction motor. Test results showed that Fuzzy-Backstepping can increase the response to changes speed in electric car. System testing is done with variations of the reference point setting speed control system, the simulation results of the research showed that the IFOC method is not perfect in terms of induction motor speed regulation if itâs not use speed control. Fuzzy-Backstepping control is needed which can improve the response of output, so that the induction motor has a good performance, small oscillations when start working up to speed reference.Keywords: Fuzzy-Backstepping, IFOC, induction motor

Finding victims at a disaster site is the primary goal of Search-and-Rescue (SAR) operations. Many technologies created from research for searching disaster victims through aerial imaging. but, most of them are difficult to detect victims at tsunami disaster sites with victims and backgrounds which are look similar. This research collects post-tsunami aerial imaging data from the internet to builds dataset and model for detecting tsunami disaster victims. Datasets are built based on distance differences from features every sample using Histogram-of-Oriented-Gradient (HOG) method. We use the longest distance to collect samples from photo to generate victim and non-victim samples. We claim steps to collect samples by measuring HOG feature distance from all samples. the longest distance between samples will take as a candidate to build the dataset, then classify victim (positives) and non-victim (negatives) samples manually. The dataset of tsunami disaster victims was re-analyzed using cross-validation Leave-One-Out (LOO) with Support-Vector-Machine (SVM) method. The experimental results show the performance of two test photos with 61.70% precision, 77.60% accuracy, 74.36% recall and f-measure 67.44% to distinguish victim (positives) and non-victim (negatives).

Six legged robot (hexapod) has advantage over wheeled robot in its capability to walk over rough terrain. In this paper, hexapod mobility will be tested in order to measure its performance in walk through beam and stair. Behavior based architecture will be used in hexpod, so it can react quickly. Autonomous navigation application has been chosen here in order to prove that the architecture is running well. From simulation result, it can be seen that behavior based hexapod robot has good mobility (it can walk through obstacle that has 10 cm height) and it can accomplish its task to avoid the obstacles and find the light source. Abstract in Bahasa Indonesia: Robot berkaki enam (hexapod) memiliki kelebihan dibanding robot beroda dalam hal kemampuannya melewati daerah tidak rata. Pada penelitian ini, mobilitas pergerakan hexapod akan diuji untuk mengetahui performanya dalam melewati balok dan tangga. Supaya dapat bereaksi dengan cepat, maka arsitektur behavior based akan digunakan pada hexapod. Aplikasi navigasi otonom dipilih untuk menunjukkan bahwa arsitektur tersebut berjalan dengan baik. Dari hasil simulasi nampak bahwa behavior based hexapod robot memiliki mobilitas yang baik (mampu melewati halangan setinggi maksimal 10 cm) dan dapat menyelesaikan tugasnya untuk menghindari halangan dan menemukan sumber cahaya. Kata kunci: mobilitas, hexapod robot, behavior based architecture, sistem navigasi otonom

Searching the accident site of a missing airplane is the primary step taken by the search and rescue team before rescuing the victims. However, due to the vast exploration area, lack of technology, no access road, and rough terrain make the search process nontrivial and thus causing much delay in handling the victims. Therefore, this paper aims to develop an automatic wrecked airplane detection system using visual information taken from aerial images such as from a camera. A new deep network is proposed to distinguish robustly the wrecked airplane that has high pose, scale, color variation, and high deformable object. The network leverages the last layers to capture more abstract and semantics information for robust wrecked airplane detection. The network is intertwined by adding more extra layers connected at the end of the layers. To reduce missing detection which is crucial for wrecked airplane detection, an image is then composed into five patches going feed-forwarded to the net in a convolutional manner. Experiments show very well that the proposed method successfully reaches AP=91.87%, and we believe it could bring many benefits for the search and rescue team for accelerating the searching of wrecked airplanes and thus reducing the number of victims.
