Proceeding of the Electrical Engineering Computer Science and Informatics Vol 1: EECSI 2014
Publisher : IAES Indonesia Section

In a power distribution system it is expected that the current and voltage values to be maintained constant both in terms of magnitude and frequency. However, distortion of waveforms as a result of non-linear loads connected to system is widely found in a form of harmonics. Harmonics are sinusoidal signals whose frequencies multiples of the fundamental frequency. The severity of harmonics content is commonly stated using Total Harmonics Distortion (THD), revealing the ratio of the Root Mean Square (RMS) values of all harmonic components to its fundamental component, and is expressed in percentage (%). The harmonics could engender undesired effects in some appliances. In this paper, an effort to minimize the THD value in an inverter design is described. Less harmonics were obtained using Buck-Boost Converter and Sinusoidal Pulse Width Modulation (SPWM) Method. Analysis results showed a THD reduction of 4.58 % and 4.33 % for current and voltage respectively.

Publisher : IAES Indonesia Section

In recent years, people have difficulty to breathe a good air quality. It is caused by vehicle emission, household combustion devices, forest fires, and industrial facilities are regular sources of air pollutants. These air pollutants can impair people health and behavior. It means that decreasing oxygen supply can reduce our immune system. The effect of reducing oxygen in our blood cause rapid fatigue, difficulty breathing, muscle pain, eye irritation and even more severe would have a heart attack. Monitoring peoples' health is one of solutions to increase the quality of human life. The pulse oximetry widely used to measure the oxygen level or oxygen saturation (SpO2) in the blood. While it has long been an important tool in clinical practice, pulse oximetry has become a popular medical tool for outside hospital environment use. Pulse oximetery work by the principles of spectrophotometry: the relative absorption of red (absorbed by deoxygenated blood) and infrared (absorbed by oxygenated blood) light of the systolic component of the absorption waveform correlates to arterial blood oxygen saturations. Patients usually take measure using pulse oxymetry in a stationary condition. While pulse oximetry recording a patient's oxygen level, the finger should not move until the recording is completed. The previous research have been evaluated a pulse oximetry in mobile condition. This paper will investigate the relationship between oxygen saturation and light attenuation in the proposed design of the ubiquitous pulse oximetry in mobile condition. This design will help the future development of SpO2 recording ability while patient in walking condition and give good accuracy as same as off-the-shelf pulse oxymetry.

Publisher : IAES Indonesia Section

The pricing for wireless networks is developed to obtain surplus from subscribers. The linearity factors, elasticity price, price factors are discussed. the new approach of wireless pricing model proposed by previous research are approached by considering the model as the nonlinear programming problem that can be solved optimally using LINGO 13.0. The problem is considered to be nonlinear programming that can be solved using optimization tools. The solutions are expected to give some information about the connections between the acceptance factor and the price. The models attempt to maximize the total price for a connection based on QoS parameter. The maximum goal to maximum price is achieved when the provider set the increment of price change due to QoS change and amount of QoS value. The linearity parameter set up for most cases is obtained in ceiling value. Linear price factor ranges between the prescribed value especially cases when we increase the price change due to QoS change and increase the amount of QoS values.

The performance of solar panels is dependent on sunlight it receives. Therefore, it is necessary to design a device that can set the direction of the solar panel always follows the sun position based solar tracker. The two-axis sensorless trackers have used in this research to produce maximum energy conversion. Position of solar panel move based on sun position using sunrise and sunset database. By using linear interpolation the sun position in latitute and longitude for other time can be obtained during a day. Based on these value the solar panel set its position using two servo motor which drived by Arduino. This technique independent from weather conditions, although cloudy, panel position remains consistent with the maximum illumination when the weather is sunny back later. By this way, the solar panel absorbs maximum sunlight and generate maximum electricity.

Proceeding of the Electrical Engineering Computer Science and Informatics Vol 2: EECSI 2015
Publisher : IAES Indonesia Section

In this paper, a novel parallel manipulator with discrete control system is developed. An efficient method such as Inverse Static Analysis (ISA) is employed to determine the state of each actuator on parallel manipulator when the position or force of manipulator is already known. The designing a parallel manipulator with 16 actuators which are controlled discretely is a must because the mechanism will use artificial methods in dealing with the ISA problem. In this approach, mathematical model is not required. The research method used simulation software and hardware testing with the case of parallel manipulator with 16 actuators. Simulations with typical desired force inputs are presented and a good performance of the mechanism is obtained. The results showed that the parallel manipulator has the Root Mean Squared Error (RMSE) has less than 3% and can be used for artificial intelligence implementation.

This paper presents a study on design and fabrication of an electronic identification system (EIS) for some volatile organic compounds i.e. toluene, ethanol and methanol through vaporization technology. A new sensing material of roselle-chitosan blending thin film based on electrochemical deposition method was used to guarantee the differentiation and the accuracy of the identification system. Chitosan smart gel with 2% acetic acid was prepared and then roselle extract was blended to enhance the sensing properties of the chitosan film. Differentiation ability was studied by exposing 50ppm of toluene, ethanol and methanol vapor to the sensing material. The accuracy of the identification system was tested by IV electrical testing. The analyzed data demonstrated that the electronic identification system is capable of identifying different volatile organic compound gases at room temperature successfully. The roselle-chitosan film sensors showed the characteristic of a reliable sensor i.e. good sensitivity, selectivity, repeatability, recovery and stable.

Proceeding of the Electrical Engineering Computer Science and Informatics Vol 2: EECSI 2015
Publisher : IAES Indonesia Section

An accurate estimation of fingerprint orientation fields is an important step in the fingerprint classification process. Gradient-based approaches are often used for estimating orientation fields of ridge structures but this method is susceptible to noise. Enhancement of ridge direction improves the structure of orientation fields and increases the number of correct features thereby conducing the overall performance of the classification process. In this paper, we propose an algorithm to improve orientation field structures using variance of gradient. That algorithm have two steps; firstly, estimation of fingerprint orientation fields using gradient-based method, and finally, enhancement of ridge direction using minimum variance of the cross center block direction. We have used standard fingerprint database NIST-DB14 for testing of proposed algorithm to verify the degree of efficiency of algorithm. The experiment results suggest that our enhanced algorithm achieves visibly better noise resistance with other methods.
