Abstract

The Medan Central Bureau of Statistics is tasked with surveying data or calculating quality statistical data and information which includes accuracy of relevance and also for price standardization or determination. The problem in setting the price standard is because many companies raise prices without surveying data first and some other companies do not adjust the price of one to another. To handle this, one method is needed to study and analyze Distributor Item Price data to be uniform, using knowledge of artificial neural network analysis using the Levenberg-Marquardt method. With this activity the Medan Central Bureau of Statistics hopes that the company in an effort to increase customer satisfaction with the products produced can be done by producing a product or item with high quality and quality with balanced pricing in accordance with the conditions in the market (adjusted to community income). The results obtained through this study are the uniformity of the prices of distributor goods in the market, which have previously been through the process of testing and applying mathematically statistically using matlab software.Keywords: Artificial Neural Networks, Levenberg-Marquardt Method, Distributor Prices, MATLAB

Abstract

Compressed files require less disk space than files that are not compressed, so compressing is useful for backing up data by using storage space to be small or to send information over the Internet faster. MP3 makes the audio format often used because the data stored resembles the original data when recorded and has a size that is not too large compared to other formats. Users besides storing song files, they also store videos and other files and users also want the highest quality data and minimum quantity (size). So to make a lot of empty space and have a size of data that is not large on storage media, a compression method that means to shorten the size of the bits needed for data is needed. Algorithms used in the compression process, including the Levenstein algorithm which is a type of lossless compression. Applying the Levenstein algorithm to the compression process the author wants to know the performance of compression when done by compressing MP3 files, so that large MP3 files will be compressed into smaller sizes, so that the transmission process is carried out faster and reduces the data storage location.Keywords: MP3, File, Levenstein

Abstract

Pengolahan citra digital merupakan proses yang bertujuan untuk memanipulasi dan menganalisa citra dengan bantuan komputer. Salah satu teknik pengolahan citra yang di gunakan adalah deteksi tepi (edge detection). Deteksi tepi adalah proses untuk menentukan lokasi titk-titik yang merupakan tepi objek. Data yang digunakan dalam deteksi tepi berupa citra digital. Citra dari sudut pandang matematis, merupakan fungsi menerus (continue) dari intensitas cahaya pada bidang dua dimensi f(x,y), dengan x dan y adalah koordinat special dan amplitudo f  pada pasangan (x,y) yang disebut intensitas atau derajat keabuan citra pada titik tersebut. Jika x, y, dan f  semuanya berhingga, dan nilainya diskrit, citra tersebut merupakan citra digital. Menurut Ayu Leonitami, Salah satu metode yang dapat digunakan dalam pendektesian tepi adalah menggunakan metode Robinson operator 3 level. Pendektesian Robinson operator 3 level bukan hanya melakukan proses pendektesian tepi dari arah vertikal dan horisontal saja seperti metode Robert’s operator dan sobel operator lebih sensitive terhadap tepi diagonal, sedangkan robinson operator 3 level  melakukan pencarian tepi dengan menggunakan delapan arah mata angin, sama halnya dengan proses pendektesian tepi prewitt dan kirsch operator bedanya hanya pada nilai kernel (mask).

Abstract

Data adalah sesuatu yang belum mempunyai arti bagi penerimanya dan masih memerlukan adanya suatu pengolahan. Data bisa berujut suatu keadaan, gambar, suara, huruf, angka, matematika, bahasa ataupun simbol-simbol lainnya yang bisa kita gunakan sebagai bahan untuk melihat lingkungan, obyek, kejadian ataupunsuatu konsep. Besarnya ukuran data yang harus dikirim melampaui kecepatan transmisi yang dimiliki oleh perangkat keras yang ada, sehingga masih terdapat delay time yang relatife besar. Selain media penyimpanan seperti floppy disk, hard disk, dan compact disk mempunyai kapasitas yang terbatas. Ada banyak teori dan algoritma  untuk kompresi data, diantaranya metode Huffman, Run- Legth Encoding (RLE), Lempel-Zip-Weleh (LZW), Shanon – Fano, dan beberapa algoritma lainnya.

Abstract

Fuji apples (Malus Domestika) are fruits that contain a lot of antioxidants. Besides the fruit flesh, the apple also contains pectin. Fuji apples are red and have a yellow line. The size of apples can affect the selling price of apples, the determination of the size of apples can be seen from the size of the diameter, measuring the diameter of apples is usually done visually by comparing apples. Based on these problems, a research is needed to develop a system to determine the diameter of fuji apples by using image processing techniques to find the diameter. This measurement process uses the matlab application and tests with the sobel edge detection method and image processing to see the more visible edges of the lines. The results showed that the developed system was able to obtain images and identify the diameter of fuji apples
