Abstract

Database Server applications are now widely used by institutions or institutions for various purposes. Most users detect the typing error manually so it is less effective. The problem that often occurs is writing or typing due to the sensitivity of the programming language. For example uppercase and lowercase letters, periods and commas, or other punctuation marks. Apart from these problems users of the MySQL application generally use tools to assist in database creation or in the manipulation process so that the Query structure of SQL is often forgotten. The Knuth-Morris Pratt algorithm is an algorithm used to perform string matching processes. This algorithm is an Exact String Matching Algorithm type which is matching strings correctly with the arrangement of characters in a matched string having the number or sequence of characters in the same string. The Knuth-Morris Pratt algorithm is part of the string search process that plays an important role in detecting errors faster and more efficiently. To find out the SQL typing error using the SQL command error detection application, the user first enters the SQL file containing the database structure. After that, the user also types in the SQL Query to be checked. Through this step, a comparison is made between the queries inputted by users with the SQL structure.

Abstract

Digital imagery requires development with several methods for storing images. Images often experience decreased resolutions during compression and de-compression. To reduce the storage size needed for high resolution digital photos, it is necessary to compress and thus reduce the file size. Compression is the process of eliminating data redundancy or transforming data into shapes that occupy little storage space. A standard JPEG is a collaboration between the International Telecommunication Union (ITU), the International Organization for Standardization (ISO), and the International Electrotechnical Commission (IEC). The Zig zag method for drawing a small number of devices is applied to an image with different brightness levels for values different from the bit rate (bpp) using the zig zag algorithm.

Abstract

Kegiatan proses belajar mengajar dan penyajian materi pembelajaran internet saat ini masih didominasi oleh pengajar sehingga mengakibatkan peserta didik mudah jenuh, kurang kreatif, kurang inisiatif dan terlalu bergantung pada si pengajar. Sebagai contoh pengajar memberikan materi dan peserta didik hanya menulis dan medengarkan sehingga membuat siswa menjadi pasif dan bosan karena siswa pasif maka pengetahuan yang diperoleh mudah dilupakan. Oleh karena itu dibutuhkan aplikasi pembelajaran yang menarik dan interaktif untuk menunjang minat peserta didik dalam belajar menggunakan metode computer based instruction. Metode computer based instruction sangat cocok diterapkan pada proses belajar mengajar khususnya dalam materi pembelajaran internet, agar peserta didik lebih cepat dan mudah memahami materi pembelajarn internet yang disajikan karena dapat menampilkan bentuk nyata dari materi yang disampaikan dengan menggunakan gambar, slide-slide dan video.

Abstract

CU Damai Sejahtera is one of the cooperatives that move in the business of saving and loan. This has the same role as other large financial institutions such as banks in improving the economy of the community, in particular, is a member of CU itself. As a financial institution, bad credit is a major problem that is very influential on the sustainability of a financial institution. loss of earnings and the threat of profitability is a matter of caution in lending. Credit collectibility as one form of classification will facilitate the classification of each member data based on supporting criteria. The result of a decision tree that produces information in the form of a rule, will facilitate the analysis and retrieval later. With decision tree using C5.0 algorithm is expected to process information digging faster and optimal with bigger data capacity, so that errors generated in decision making more minimized.
