Abstract

The use of digital images from scanned documents is commonly used both for data backup and for further processing. However, often the digital image obtained is not optimum due to various factors like noise. The method to improve the quality of digital images is to filter images using the Thresholding method. This study compares three Thresholding methods, which are Simple Thresholding, Adaptive-Gaussian Thresholding, and Otsu Binarization. All three methods have advantages and disadvantages. However, using the MSE and PSNR assessment parameters, the Simple Thresholding method shows better quality with an MSE value of 5,196.76, followed by Otsu Binarization with a value of 5,934.10, and Adaptive-Gaussian Thresholding with a value of 9,025.29. Meanwhile, by using PSNR, the value for Simple Thresholding is 13.37, followed by Otsu Binarization with a value of 12.47, and Adaptive-Gaussian Thresholding with a value of 10.31.

Abstract

Ikan air tawar merupakan komoditas yang selama ini menjadi andalan di bidang pangan. Budidaya ikan air tawar semakin hari semakin menggiurkan. Menurut laporan Badan Pangan PBB, pada tahun 2021 konsumsi ikan perkapita penduduk dunia akan mencapai 19,6 kg per tahun. Dari sisi produksi, pada tahun 2011 produksi perikanan nasional mencapai 12,39 juta ton. Dari jumlah itu, produksi perikanan tangkap sebanyak 5,41 juta ton dan produksi perikanan budidaya 6,98 juta ton. Dari total produksi perikanan budidaya, jumlah budidaya ikan dalam kolam air tawar menyumbangkan angka hingga 1,1 juta ton. Kecilnya jumlah yang disumbangkan oleh budidaya ikan air tawar adalah karena kurangnya pengetahuan masyarakat mengenai budidaya ikan air tawar tersebut, dari mulai jenis ikan air tawar yang ada, cara budidaya dan pangsa pasar yang akan dituju. Tujuan dari penulisan ini adalah pembuatan website untuk memberikan informasi mengenai jenis ikan air tawar yang ada di pulau jawa, cara budidaya yang mudah dengan menggunakan video dan cara budidaya dengan memanfaatkan lahan yang sempit sesuai dengan ketersediaan lahan yang ada. Aplikasi berbasis Web informasi penyebaran dan budidaya ikan air tawar yang akan dibuat menggunakan dreamweaver, appserv dan phpmyadmin. Metode penelitian yang digunakan adalah dengan studi pustaka dan observasi ke tempat budidaya mengenai budidaya ikan air tawar.

Abstract

Abstract: The fluctuative of stock prices in a secondary market provide the possibility for investors/traders to gain profits through the difference in stock prices (capital gain). In order to obtain these benefits, it is necessary to analyze before buying shares, through fundamental and technical analysis. One of several methods in Technical Analysis is Simple Moving Average Method. This method can be used to predict (forecast) stock prices by calculating moving average of the stock price history. Historical stock prices can be obtained in real time using the Web Scrapper technique, so the results is more quickly and accurately. Using the MAPE (Mean Absolute Percent Error) method, the level of accuracy of forecasting can be calculated. As a result, the program was able to run successfully and was able to display the value of forecasting and the level of accuracy for the entire data tested in LQ45. Besides forecasting with a value of N = 5 has the highest level of accuracy that reaches 97,6 % while the lowest one is using the value of N = 30 which is 95,0 %.

Abstract

Abstract : The digital era forces people to digitize in all fields. Digital product that is often found is digital image. One kind of digital image application is the use of a digital image signature embedded in a document. However, often the results are unsatisfactory, such as background color problems, noise, lack of clarity, etc. The quality of digital image signatures can be improved by implementing the Otsu Thresholding and Sauvola methods. These two methods were chosen because they are widely used in document image quality improvement. The purpose of this study is to produce a better digital image signature and to compare the performance of these two methods. The results showed that the quality of the images produced by these two methods was better than the original image or by using standard filters from a word processing application. Meanwhile, from the two methods used, Sauvola's method was slightly better than Otsu's method. In terms of visual evaluations, the Sauvola method total score is 13 compare to Otsu method score that is 11. Meanwhile, the PSNR ratio show that the two methods give the same results, that is 34,571 db.

Abstract

Character extraction in digital images is an interesting topic in the field of image processing. One of the steps in this processes is image preprocessing, that is preparing the image before extraction. There are many methods that can be used, one of which is the WAN method. The WAN method is a development of the Sauvola method, a method commonly used to improve the quality of text images. In an journal article, the WAN method provides better results than other methods for improving the quality of text images. In this research, this claim was tested by applying it as a preprocessing process in text character extraction using Optical Character Recognition (OCR) technology. The purpose of this research is to find out how well the WAN method is used compared to other methods. The result is that OCR technology give better result to an original image compare to image with preprocessing process, including using WAN method with a match rate of 52.33%. Meanwhile, if the preprocessing process is carried out first, the WAN method gives better results than the Sauvola method with a match rate of 26.93% for the WAN method and 23.27 for the Sauvola method.
