Abstract

Today, Banyubening Hospital still use the manual information system which the data of patients are done by written the file. This method has some weaknesses, suchas human error or takes a long time. The purpose of the research is to develop information system inpatient at RSI Banyubening Boyolali. The development system isthe processing data of inpatient that is done by human before is changed to be computer based system. The changing is needed in order to make easier processing data andpresent information well to avoid some weaknesses hat are often found in the system manual processing.

Abstract

CD rental at Tisanda is uncomputerized that caused slow in time and energy-consuming transaction. Information System of CD rental is an alternative solution to solve problem in the data analysis. CD rental information system is a system that has borrowing and repayment process, including providing information about the number of existing CDs. This study discusses lending transactions, refunds, and penalties. This research method is observation, interviews, and literature. The system is built using Visual Basic as the language program and mySQL as database with mysql-connector-odbc-win32-3:51:23 as connectors. CD Rental Information System includes the CD report, rent, damage, and loss of earnings. This system is more efficient because it can minimize data storage. In addition, it takes less energy and need a short time to input data or reports and data can be accessed more quickly than before. Rental Information System at Tisanda alsouses a barcode reader so the transactions can be faster.

Abstract

Abstract— Reversible watermarking schemes are widely used to maintain the authenticity of the digital image. This research will discuss a method on histogram modification of difference image in which the difference image is created from the difference value of adjacent pixels of the image grayscale.  Embedding process begins by dividing the host image and watermark into b blocks, followed by making a difference image of the host image block. From the difference image histogram, determine the peak value, and modify the histogram based on the peak value. Then, insert each block of the watermark to the difference image that has been modified and transform back into the grayscale image.Extraction and recovery process is the inverted version of the embedding stage. This process begins by dividing the watermarked image into b blocks, followed by making a difference image of each block. Then, extract the data and shift difference image histogram using a peak value. That difference image is transformed back into a grayscale image. Experimental results demonstrate that the average insertion capacity is 14% greater than Xue's with PSNR value over 48 dB for 4 x 4 pixels and 23 % greater with PSNR over 46 dB for 8 x 8 pixels. From the comparison of robustness to line and salt n’ pepper on the density of 0.05 noises is obtained that the watermark with ECC is more robust than a watermark without ECC. JPEG compression in lossless mode may be applied to the watermarked image. Multiple insertion of watermark can be done with the consequence that the more insertions will result in lower PSNR values.Keywords—difference image, histogram modification, reversible watermarking
