In this area there is a meeting of plate of Indo-Australia with plate of Eurasia which is if colliding head-on potency can generate tsunami. Seeing this existing condition, it is needed a study to know how susceptible level of South East Java Province regional to get disaster of tsunami. Based on the tsunami was occurred in Aceh Indonesia on December 26, 2004 was killed more than 200.000 peoples, the tsunami disaster management become very important to study. One of the studies ishow to predict the tsunami runup along shoreline of southern beach of East Java Province Indonesia. According to the geological data, area of east Java Ocean has high potential of earthquake. The history shows that there are many time tsunami occurred in East Java. Based on the initial study, one of the areas predicted as dangerous area for the tsunami is Pacitan city. To minimize the effect of tsunami hazard, prediction of inundation area base on the numerical model simulation of tsunami runup was done for Pacitan city. In this research predicting of inundation area caused by tsunami was studied. GIS was used astool to predict the inundation area. From this research it can be shown that numerical model of tsunami can be used to predict the runup. Base on runup elevation, inundation area can be predicted well by using GIS]]>

<![CDATA[This paper presents the development of smart energy monitoring and control system for Renewable Energy Hybrid Power Generation System (REHPGS) using SCADA. REHPGS model consists of photovoltaic, wind and gen-set system. SCADA is used to monitor and control the operation of Hybrid Power System (HPS) in real time. This paper planned a concept of smart grid by VisconDua Remote Terminal Unit (RTU)-IO Module. The RTU is responsible to collect information from power HPS plant. SCADA Expert controller is introduced to automatically control renewable energy sources. The monitoring and control system of REHPGS operated in real time and can perform under various operating conditions. The HPS plant will be fully automated, which mean the power plant would rely on the SCADA system on all its operations. Results show that the proposed system has the capability to monitor and optimize the output power generation of REHPGS]]>

<![CDATA[Currently, a common method for identifying a person is by means of an identitycard (ID) or combination of an ID and password. The approaches are not very reliable, since the ID can be stolen and password can be forgotten. A more reliable identification system is required. In the last decades, identification systems based on biometrics have been gaining attention, since they are more reliable. Biometrics-based devices identify people based on their physical or psychological characteristics, such as palmprints, fingerprints, gait and iris. Unlike fingerprints or palmprints, irides features distribute randomly, and the features were unique; the features between right and left eyes aredifferent, as well as between twins. Therefore, in addition to reliability, the use of irides can enhance identification accuracy. Purpose of the paper was to improve identification rate of an iris identification method, using ordinal measure of Discrete Cosine Transform (DCT) coefficient. The input iris image was tiled into blocks of 8x8 pixels, then the DCT was applied to each blocks. The AC coefficients of each block were sorted from the smallest to the largest values, in which the sorted values were referred to as ordinal measures.Identification was accomplished by measuring a distance between the ordinal measure of the input images with the ones of the existing images in the database using Minkwoski distance metric. Proposed method increased the averaged identification rate as compared to the previous method by nearly twice from 33% to 61.4%.]]>

<![CDATA[Nowadays, the development of wireless communication systems will be refer to user cooperative communication system in which a source information can transmit data to a destination through a relay. This can reduce the effect of fading on wireless communication channel which is a major problem in wireless communication system that can degrade the system performance. In this paper, we investigate the performance of multi-relay cooperative communication using decode and forward protocol in terms of channel capacity, bit error rate (BER) and throughput. The use of decode and forward protocol in multi-relay cooperative communication offers cooperation among users to generate virtual multiple antennas to increase the channel capacity and also can give better system performance. Furthermore, the simulation model of the system and computer simulation is developed to evaluate the performance of multi-relay cooperative communication. The simulation result shows that the channel capacity increases as the value of signal to noise ratio (SNR) increases. Also, the channel capacity increases as the number of relays increases. Moreover, the performance of multi-relay cooperative communication performs better than a single-relay cooperative communication by using decode and forward protocol in terms of BER. Furthermore, multi-relay cooperative communication provides a good throughput of the system compared to a single-relay. Therefore, the multi-relay cooperative communication is useful to mitigate the effects of channel fading, increase the channel capacity, improve the system performance and provide a good throughput by exploiting decode and forward protocol.]]>

<![CDATA[Irrigation water management problems will arise if there is a shortage of waterin rice fields. Shortage of water in rice fields can be evaluated by the efficiency of existing irrigation.Based on the Indonesian‟s irrigation design criteria 65%, the project efficiency for Irrigation Planning is 65%. This value when compared to some countries in Asia was still much greater. This might be caused by undeterminating the water losses in the rice field. The study aims to determine the efficiency of irrigation in rice fields (Field Application Efficiency) is actually through direct measurements in the field, started at the land preparation up to the growth of rice plants. Measurements were taken at one tertiary JKr21Kr in Krueng Jreue Irrigation Region. To evaluate the efficiency of irrigation in ricefields used two methods of measurement. Inflow-outflow method for measuring the delivery of irrigation water in rice fields (Vf) which use the modified pipes that serves as the entrance and exit of water in the tertiary, the difference between incoming water and outgoing water is the amount of water used in rice fields. Water balance in the field is measured using Drum technique method with a diameter of 50 cm and height 125 cm. The drums are planted in the ground and a quarter of the height of the drum located above thesurface. By this equipment, the evapotranspiration parameters, percolation and effective rainfall can be obtained. These results showthat the efficiency of irrigation in rice fields (Ea) of 65.29%. It means that actually the project efficiency is 42.44% far below than Indonesian‟s criteria.]]>

<![CDATA[Recently, there has been significant research interest in cogasification of coaland various types of biomass blends to improve biomass gasification and syngasproduction. In addition, ash present in biomass catalyses the gasification of coal. This experiment was conducted on the cogasification of various types of coal and biomass using drop tube gasifier under two sets temperatures 1173 and 1273K respectively. Most of the reactions are considered as endothermic, the heat input is needed to conduct the reactions. The additions of biomass to NL coal during co-gasification give no effect on gasification, since the reaction is endothermic. The increasing temperature from 1173 to 1273K only give small increase in the yield gas and efficiency due to the short of residence time]]>

<![CDATA[The integrity of electrical power equipment is of paramount importance when itsupplies electricity throughout a facility. However, the reliability of the equipments will degraded after sometime, and appropriate maintenance has to be taken accordingly to avoid future faults. Infrared thermography (IRT) image analysis is a commonly used technique for diagnosing the reliability of electrical equipments. Conventionally, the analysis of infrared image is done manually and takes very long time for further analysis. This paper proposes an automatic thermal fault detection and classification system for evaluating thecondition of electrical equipment by analyzing its infrared image. First, the image is segmented to find the target region of interest (ROI). The detected regions which have the same region properties are grouped together in order to remove the unwanted regions. Finally, statistical features from each detected region are extracted and classified using the support vector machine (SVM) algorithm. The thermal condition of electrical equipments is evaluated based on qualitative measurement technique. The experimental result shows that the proposed system can detect and classify the thermal condition of electrical equipments.]]>

<![CDATA[Patchouli (Pogostemon cablin) is one species of the vegetation that produces essential oil known as patchouli oil. The quantity of patchouli alcohol contained in patchouli oil determines the oil quality. This study investigates fractional distillation of patchouli oils (Pogostemon cablin) to increase the level of patchouli alcohol in patchouli oils. The separation process is carried out by fractional distillation method applying four fractionation temperatures: 120°C, 125°C, 130°C, and 135°C. The compositions of each fraction were identified using Gas Chromatography – Mass Spectrometry (GC-MS). Patchouli oil A and B with initial patchouli alcohol content of 27.03% and 36.87% were successfully fractionated resulting four fractions of patchouli oils. The final levels of patchouli alcohol are increased to become 35.35% and 43.62%, respectively as well as the densities of the four fractions]]>
