This phenomenon may alter the pattern of some component, such as hydrology, where changes of hydrology further affect the gravity field around the area as well. In this research, the changes in gravity field are estimated using the temporal gravity data from GRACE satellite observations. The data used in this research is the temporal monthly data of the ITSG-Grace2016 from 2014 to 2016, which was the chosen time period to give the latest information available for the temporal gravity data in the region. The obtained gravity field is analysis using the topography maps also the land cover map of South Kalimantan. This research concluded that there have been variations in the mean gradient of gravity in South Kalimantan for period of 2014, 2015 and 2016 with values ranging from -2.23×10-13 to $4.19 mathrm{x} 10^{14}$ mgal. The peak point during this period of time takes place on April 2015, while the lowest is on January 2014. It has also been approved that the gravity value is affected by the mass of water, meaning that the gravity gradient values can be used to determine the condition of hydrology in peatland area.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124653329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Bogie maintenance in Indonesian commercial trains is done every 350.000 km-400.000 km. But many types of Bogie K5 is fail to operate before reaching a distance of 350.000 km. The Bogie K5 component can not being replaced by other Bogie type components because the specifications are different. This research is done to determine the critical components and its maintenance plan. The method used is reliability centered maintenance (RCM). The result shows that there are 21 components of Bogie K5 that categorized in safety problem, outage problem, economic problem and hidden failure. Brake block component becomes a critical component because it is included in the safety problem component and has the highest RPN (Risk Priority Number) value compared to other components. The RCM action is develop based on conditional directed (CD) and time directed (TD) category. Based on data distribution test for component of brake block, component time to failure is categorized as weibul distribution and component time to repair is categorized as lognormal distribution. The goodness of fit test shows that hypothesis testing is acceptable. For mean time to failures, the average time is 59,44 days, which means that the average component will be damaged after 59,44 days of operation. As for the mean time to repair value is 9,18 days which means that the average time to fix the critical component is 9,18 days.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125390833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The code has abilities of both simulating normal and abnormal conditions of the reactor. It was developed based on interaction among governing equations of mass and energy conservations, fuel rod heat conduction, and point kinetics. For simplicity, the code considers only one type of control rod rather than three types of control rods as used in the reactor. Calculation results of the power and axial coolant temperature distribution at rated power show a sufficient agreement with those of experimental data. Results of the plant dynamics analysis by using the code also show a correct plant's behavior as those of general light water reactors. Rough safety analysis of an excess reactivity insertion was carried out and the calculation results show that the limit of reactor safety is satisfied. It might improve the code by consideration of three types of control rods to decrease the calculation errors. However, the code was satisfied to be used as a tool for both supporting the nuclear training center and safety analysis.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127047713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Face recognition concerns to identify person from an image set. In general there are three face recognition classes, i.e., holistic based, feature-based, and hybrid methods. Fisherfaces extends Eigenfaces approach using Fisher's linear discriminant to improve classification rate by maximising the ratio of between-class to within-class scatters. In the other hand, local binary pattern employs shape and texture in local pixel neighbourhoods to build a global representation of a face image. Both methods are implemented and analysed using three distinct face image dataset and a real time video application. The accuracy, training and testing time for both algorithms are measured in some experiments using k-fold cross validation scheme. From experiment result, it is concluded that Fisherfaces has a good prediction time that makes it a good choice for real time face recognition applications. In contrast, local binary pattern can handle classifier addition, so it can be used in dynamic face recognition scenarios.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133466594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensor model is claimed with a number of advantages especially to solve the problem on the application of conductance type sensors. SKU:SEN0193 is one of a low cost soil moisture sensor which is available on the commercial market. Before applied, it is necessary to know the performance and characteristic of the sensor for local soil application. The purpose of this research is to calibrate the soil moisture sensor for soil humidity measurement. For this, the sensor coupled with such signal conditioning circuit is connected to an Arduino microcontroller and LCD for data acquisition system. The sensor responses to varied moisture of soil samples are compared to the gravimetric methods. In this research, the sensor is calibrated for sandy loam soil texture obtained from Bangka Regency. The result showed that soil moisture content readings by SKU:SEN0193 is not affected by different volume of soil and soil temperature, but is little affected by ambient environmental temperature conditions. There is direct relationship between the soil moisture content (y) and the sensor response (x), sensor performs well so it can be used to measure the moisture content of sandy clay soil sample.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115825413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modification of flow along the fuselage becomes very important in creating the ability to maneuver to avoid the stall. Addition of canard on the fuselage will modify the flow so that it can delay the occurrence of the stall. The canard configuration will determine the extent to which the aircraft can hold on so as not to fall at a high angle of attack. In this study will examine how the configuration of canard deflection angle can optimize the downwash flow of the canard and the flow interaction along the main wing to keep the streamline and delay the stall. The use of visualization method using water tunnel will give detail result visually or aerodynamic force that happened. Also, the use of computational fluid dynamics (CFD) computation method is used as validation of experimental data to obtain accurate results. The results show that the deflection angle setting can delay the occurrence of aircraft stalls. At the canard deflection angle of 300-400could delay the stall until the maximum angle of attack 700.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"273-276 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130778418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this research is to analyze sea level rise from long period tide gauge data. This research uses tide gauge data in Semarang and Prigi station period 1996 to 2015. Data processing is done using Matlab 2013b to plot sea level rise data and to calculate the the trend of sea level rise. Initial stage of data processing is quality control of tide gauge data by eliminating outlier data with confidence level of three sigmas and filled empty data with NaN (Not A Number). Shifting correction is done if there is reference bias at some period of data recording at a station. Processing followed by calculation of monthly MSL (Mean Sea Level) and SLR (Sea Level Rise) with linear regression to calculate trend value of sea level rise. The result of this research is at Semarang tidal station produces SLR 4,4 mm/year with SEE 0,1 mm. At Prigi station, SLR calculation is divided into three periods namely 1996 to 1999, 2002 to 2009 and 2010 to 2015 due to more than 1 year data vacuum. Data period 1996 to 1999 shows the falling in sea level about 10.2 mm/yr with SEE 0.3 mm, 2002 to 2009 data period produces sea level rise 25.5 mm/yr with SEE 0.2 mm, and 2010 to 2015 data period shows the falling in sea level about 0.07 mm/yr with SEE 0.08 mm.
