A wireless network technology is developed as the solution for the transportation business issue, named Vehicular ad-hoc Network (VANETs) in the context of Intelligent Transportation System (ITS). The vehicle density and speed affect the network performance. This research aims to analyze the performance of cluster formation method on VANET networks. The modeling of Semarang Highway has been used as...
Spatial data are indispensable in supporting disaster responders. Accurate locations of disaster areas will help responders to create an appropriate response in reducing the impact of the disaster. Indonesian Geospatial Information Agency (BIG-Badan Informasi Geospasial) has made spatial data available for emergency response activities across the country. In 2011, BIG launched a geoportal, which is...
An experimental investigation was conducted to study the crush-worthiness parameters and behaviour of the bamboo-epoxy composite tube with chamfering angle 45° at one end. Quasi-static compressive loadings were applied axially to investigate the response of force-displacement during progressive collapses. The Shimadzu concrete compression testing machine with capacity 2000 KN was used in this experiment...
South coast of Java has been highly preferred as the placement location of wave energy converter, due to its relatively huge energy potential. Furthermore, linear permanent magnet generator (LPMG) has became one of the popular methods to convert wave energy to electrical energy. Based on the shape of stator core, there are several models of LPMG. Quasi-flat LPMG is one of them, which has rectangular...
In the era of the development of mobile technology, direct communication becomes a rare thing between humans to their families, causing the spatial communication between families, be it close family, distant family, or extended family. This can lead to familial relationships disappear, so that the grandchildren do not know their family tree properly. The “Geni.com” app provides a feature to record...
Nowadays, diving is done for a variety of purposes. One type of diving activity is scuba diving. In the process, time and scuba diving area are limited by the availability of gas for breathing. This research focused on the design of single passenger underwater vehicle frame. Frame is a major component of the underwater vehicle functioning as a holder of the load and a place to put all the components...
This paper discusses an early warning system of wireless electronic information board based on frequency modulation (FM) radio to display the tsunami disaster risk visually. The system will be implemented in Cilacap District located on the confluence of two major plates. The display of proposed system is designed in multicolor using dot matrix panel P10 which has 32 × 16 pixels resolution. To be implementable...
Dynamic Compression Plate (DCP) Is the most popular type of implant plate that facilitate compressing the fracture bone during implantation. However, the price of DCP is still expensive according to developing contries people. The price of DCP mostly related to its manufacturing that involved many machining processes. The proposed solution offered in this study was to change DCP manufacturing process...
The objectives of this project are to determine the behaviour to withstand a load that is gradually increased in one position such as standing on one leg and finding the methodology in conducting this experiment. The observation is mainly focused on the UHMWPE acetabular cup. The prosthesis was made by the assembly of Titanium grade-2 femoral stem, SS316L femoral ball, and UHMWPE acetabular cup. The...
University Course Timetabling Problem (UCTP) is common problem on high school and university. This problem is already solved by numerous method such as genetic algorithm, reinforcement learning algorithm, ant colony algorithm, or combination between them. Although the algorithms solved the timetabling problem, the previous researches limited discuss the pseudocode implementation only. This research...
The use of online collaboration in developing documents is still not popular in Indonesian public institutions. Therefore, it takes many budgets and much time to make a public document. Meanwhile, the government should improve the quality of public services effectively and efficiently. This paper discusses the comparison of three selected document management system (DMS) features, Doccept, eFileCabinet,...
This paper presents the development of an automatic pointing system for very small aperture terminal (VSAT) antenna. The system which uses AVR microcontroller as a main controller unit (MCU) is featured with non-horizontal alignment autocorrect. User interface is implemented using android smartphone connected wirelessly to the MCU using bluetooth module. The android smartphone also reads the latitude...
Part of speech tagging has some different methods or techniques to the problem in assigning each word of a text with a part-of-speech tag. In this paper, we conducted some part-of-speech tagging techniques for Bahasa Indonesia experiments using statistical approach (Unigram, Hidden Markov Models) and Brill's tagger. In this study, we used Supervised POS Tagging approach requiring a large number of...
Laser is one of the light sources that transmits wavelength with frequency, phase, and polarization parameters. The response of each dielectric material to light created nonlinear in strong electromagnetic field. Nonlinearity occurs within the optical fiber with high intensity of light at the core with long span. The focus of this paper was to reduce the behavior of nonlinearity SPM (Self Phase Modulation)...
This paper presents the experimental study on small scale frequency-modulated continuous-wave (FMCW) synthetic aperture radar (SAR). The FMCW SAR system which is intended for unmanned aerial vehicle (UAV) payload uses 25–35MHz chirp signal generated using Direct Digital Synthesizer (DDS) which is transmitted at L-band frequency of 1.27GHz generated by voltage controlled oscillator (VCO). The choice...
The social media has Immense and popularity among all the services today. Data from SNS (Social Network Service) can be used for a lot of objectives such as prediction or sentiment analysis. Twitter is a SNS that has a huge data with user posting, with this significant amount of data, it has the potential of research related to text mining and could be subjected to sentiment analysis. But handling...
A number of benefits originate from the implementation of cloud computing. Cloud computing has been extensively implemented in organizations like companies and universities. However, in Indonesia cloud computing is not widely approved by universities yet. This condition can be caused by lack of trust of the universities in the risk of cloud computing implementation. This paper is intended to analyze...
Recently, MIMO-OFDM Is widely used In wireless communication standards. In several cases, it utilizes higher-order modulation technique to increase transmission rate, but on the other hand it leads to being more susceptible to bit error. In this paper, we conducted 2×2-MIMO-OFDM implementation and performed a field experiment to evaluate the performance of MIMO-OFDM with 16-QAM, 64-QAM, and 256-QAM...
This paper explains the gender recognition system through a human facial image by using the basic method of Principal Component Analysis (PCA) combined with Linear Discriminant Analysis (LDA). PCA+LDA method performance can be improved by improvising the preprocessing techniques such as resizing the image, equalizing the histogram, and removing the variation of the image background by adding oval...
