By exploring information or knowledge in a data allows an institution to improve the learning process and the quality of the institution. This research proposes feature selection techniques in improving Student's Academic Performance classification accuracy. The algorithm used is Naive Bayes, Decision Tree, and Artificial Neural Network, which will be applied to the features selection; wrapper and information gain. The application of feature selection is intended to obtain a higher accuracy value. When compared to the embedded method in previous studies, the feature selection on this experiment has a lower accuracy rate.","PeriodicalId":130873,"journal":{"name":"2017 2nd International conferences on Information Technology, Information Systems and Electrical Engineering (ICITISEE)","volume":"9 40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129830115","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}

CESM/WRF simulated climatological temperature and precipitation at 10-km resolution covering the 20-y period of 1980–1999 were evaluated using the University of East Anglia Climatic Research Unit, the University of Delaware Air Temperature and Precipitation, and the Global Precipitation Climate Center observation datasets, and the ERA-Interim reanalysis dataset. Results show that CESM/WRF performs much better than CESM does and can simulate local spatial patterns and values of precipitation and temperature for Sumatra well. CESM/WRF simulated climatological temperature and precipitation agree well with observations and reanalysis. CESM/WRF is useful for providing climate simulations at high resolution for Sumatra.","PeriodicalId":130873,"journal":{"name":"2017 2nd International conferences on Information Technology, Information Systems and Electrical Engineering (ICITISEE)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125287768","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 antenna was designed for working at three bands of frequency allocation for Long Term Evolution (LTE) i.e. 800 MHz, 1700 MHz, and 2300 MHz. The antenna was etched on the FR4/Epoxy of printed circuit board and consisted of three dipole elements for each frequency, with the lower frequency radiating element was folded to reduce the antenna size. The probe feeding method was applied and the input impedance was adjusted by the size of microstrip line from antenna to feeder. The designed antenna has been fabricated and a series of measurement was conducted to validate the design. The findings show the measured antenna characteristic is agree to simulated results and satisfy the requirements to be implemented for LTE base station antenna.","PeriodicalId":130873,"journal":{"name":"2017 2nd International conferences on Information Technology, Information Systems and Electrical Engineering (ICITISEE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125381931","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 storing of dances in the form of video format seems inadequate since studying, comparing, and analyzing the video is cumbersome task. This paper discuses about the feasibility study of scripting the Indonesian traditional dances in XML format. Some studies related to these attempts are presented such as Indonesian traditional dances and current technological approach, the motion / gesture capture and recognition, and many more.

Forecasting accuracy of detection is discussed using the Mean Absolute Deviation (MAD), Mean Square Error (MSE), and Mean Absolute Percentage Error (MAPE). The result shows that Single Exponential Smoothing is considered an appropriate method to forecast the missing reports of E-Report Police Resort because it produces the smallest value of MAD and MSE.","PeriodicalId":130873,"journal":{"name":"2017 2nd International conferences on Information Technology, Information Systems and Electrical Engineering (ICITISEE)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115875120","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}

Cryptography is an information security technique that turns information into another random and incomprehensible form, while steganography secures data by hiding information in storage media such as text, images, sound and video. In this research will be merged both security techniques, namely Stegocrypto. This stegocrypto uses ElGamal's elliptic curve for the coding process and utilizes noise as a steganographic medium. The elliptic curve used in this study has 2026 pairs of points. While the input of this system is an ASCII character, so input should be represented first before being processed. The process of inserting cipher with noise is done without using a marker. In this study, the stegocrypto system was successfully implemented. The system successfully encrypts and decrypts the input message. Decryption is done by reading all received stego-noise and will be read as cipher text when it is an elliptic group element. Then from the test is also obtained the influence of message length and k variables to the time required for the process of encryption and decryption.","PeriodicalId":130873,"journal":{"name":"2017 2nd International conferences on Information Technology, Information Systems and Electrical Engineering (ICITISEE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122837230","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 bias currents could control the natural frequency electronically meanwhile the filter passive and active sensitivities are low.
