Historical lightning data could be use to evaluate certain transmission line in power system network. By using historical data from lightning detection system with combined Magnetic Direction Finder and Time of Arrival method, lightning data mapping for West Java province was presented in this paper. According to the lightning data mapping from total recorded event, the peak current of the lightning...
Polymer nanocomposites have been identified to possess superior electrical insulation properties compared to its base polymer. However, weak interfacial interaction between the nanoparticles and the host polymer matrices would result in poor insulation properties. In this study, the surfaces of Boron Nitride (BN) nanoparticles were treated with atmospheric pressure plasma discharge to strengthen the...
Grounding system plays very important role in AC substation station for person and equipment safety. Proper design of grounding system is achievable by following IEEE Std-80 on safety in AC substation grounding but novice professionals find it not easy to use. The advantage of this paper presents evaluation of grounding system for AC substation by case studies presentation thus easing the understanding...
This Transformer experiences aging everyday as it gets older. The aging of transformer can be detected by assessing the condition of its oil insulation. Every transformer has its own aging rate which is influenced by many factors. This paper discusses about effects of lifetime and loading factor on DGA using regression linear method. 219 sample data including DGA and transformer age were collected...
Pick and Place Robot is a type of robot with “Pick and Place mechanism” designed to ease the displacement of objects from 1 position to another as desired. Some systems in the industries embrace the efficiency which is a production line usually enabled in order to produce several different types of objects in turn. Based on these circumstances, Pick and Place robot was designed to have 9 laying position...
Aesthetics is a branch of science that discusses about the philosophy of beauty and harmony among design elements. Discussion on the domain of aesthetics are often produce subjective result, where every user has their own opinion. Website is the first gateway of any universities to introduce themself. Based on aesthetics concept, the quality of a university website can only be measured well when users...
Data on agricultural commodities in Indonesia are provided Ministry of Agriculture, Republic of Indonesia which can be accessed on Agricultural Statistics Database at http://aplikasi.pertanian.go.id/bdsp/index.asp. The data are presented to the public in tabular formats. In order to provide the analytical tool for the agricultural commodities data, this study aims to develop a Spatial Online Analytical...
Facial expression recognition is an active research area in the field of signal social processing. The goal is to distinguish human emotion. The problem is similar emotion, variation of emotion, and independent object through face image. The existing research using various method for modeling human facial to entirely describe facial expression through face image. We consider to variation analysis...
Architecture patterns and tactics are established architectural solutions widely used as design decisions during software architecture design phase. Architecture pattern provides the skeleton of a system by defining the components and connector required to establish the requirements of the system. It also encourages reusing the architecture to many similar systems or family of systems. Moreover, architecture...
There are some issues with the adoption of information technology of infrastructure library (ITIL). The common issue comes from customers that always need excellent services. On the other hand, there are employees acting as an internal element of enterprise who need to be motivated while delivering the services. It has been known that the pressure at work and employees' personal problem can cause...
This paper focuses on proposing approaches for the improvement of Voice over Internet Protocol (VoIP) service quality in Wireless Mesh Network (WMN). While WMNs have self-healing, self-forming and dynamic topology features, they still pose challenges for the implementation of multimedia applications, such as voice, in various scenarios. The research has been conducted using a network simulator and...
Road accident is a widespread problem all over the world. The number of the vehicle is increasing rapidly. Therefore, the probability of an accident is also increasing. So in this paper, we propose an IoT-based system for providing safe driving. It will collect data using smartphone and show the driver about the condition of the road. We have developed an Android based application which will collect...
Visualization became one of the solutions in showing the attack on the network. With Visualize the attack, it would be easier in recognizing and conclude the pattern from the complex image visual. The target of DoS attacks can be addressed to the various parts of the network, it can be routing, web, electronic mail or DNS servers (Domain Name System). The purpose of the DoS attacks create a server...
Real-time face recognition system process divided into three steps, feature extraction, clustering, detection, and recognition. Each step uses a different method that is Local Binary Pattern (LBP), Agglomerative Hierarchical Clustering (AHC) and Euclidean Distance. Content Based Image Retrieval (CBIR), an image searching techniques based on image feature, is implemented as the searching method. Based...
This paper presents is to design swarm formation control using behavior-based for real robots. It's consists of two behavior are avoiding obstacles and formation keeping. During formation, the robots are also desired to coordinate among themselves to avoid collisions and keep formation the desired distance between each other. This design is using Fuzzy Logic Controller System. In this work a fuzzy...
The aim of this work is to design a mobile robot using WPT (Wi-Fi Position Techniques) method. The design in this research is intended to determine the mobile robot position by using the Wi-Fi module to determine the coordinates of position as determination to reach the target position and to find the strength of the detected Wi-Fi signal. Mobile robot is using to get the results of the strength of...
This paper represents a cooperative searching strategy of swarm robot in finding and localizing odor source. 3 robots, namely: Cyborg G11, Cyborg G12, and Cyborg G13 were used as agents that form the swarm in this research. The cooperation among the robots trough communication has shown the success of the swarm in odor searching. When one of the agents in swarm robot detected a high concentration...
