Abstract

Citra sangat banyak dan mudah didapatkan di berbagai tempat seperti di sosial media, browser dan berbagai situs lainnya. Hal ini membuat masyarakat dengan mudah dan cepat mengetahui informasi baik yang berada disekitar ataupun yang jauh dari jangkauan. Akan tetapi, kemudahan yang didapat menyebabkan masyarakat kesulitan dalam membedakan citra asli dan citra palsu. Kemajuan teknologi sudah memanfaatkan digitalisasi yang telah banyak dan sangat mudah ditemukan dan digunakan, sehingga banyak orang menyalahgunakan citra untuk hal-hal yang merugikan orang lain. Telah banyak ditemukan pemalsuan citra, yang menjadi alasan bagi peneliti untuk mengemukakan sebuah gagasan dalam mendeteksi image forgery untuk copymove menggunakan discrete wavelet transform (Dwt) dengan dua dimensi. Berdasarkan hasil penelitian ini, Dwt mampu membaca copy move melalui noise yang ada pada citra tanpa mengganggu citra asli, citra copymove akan dideteksi oleh sistem dengan membaca setiap wilayah citra dengan melihat perbedaan dari setiap pixel yang menghasilkan nilai noise. Nilai noise tersebut diproses dengan membandingkan nilai noise dari pixel sebelumnya sehingga menghasilkan perbedaan, maka dari itu, sistem dapat menentukan wilayah citra yang menggunakan Teknik copymove dan melakukan blok terhadap pixel tersebut

Abstract

Information systems that are well made will produce applications that have optimal performance for all accesses to the system. The problem that is often encountered is a system that is easy to hack and tamper with entering from the login system, causing the system to experience data security failure and is accompanied by very dangerous file and database damage. The Laravel Framework provides access security that is Progressive, Scalable and Community Framework to be developed by information system developers, but for the default system from Laravel 7 it is still not enough to provide a solution for data security and access levels for users. Then additional systems are needed in the form of: Secure Hashing Algorithm (SHA), Multi Level Access Algorithm (MLA) and Middleware Checking Access System to overcome data security problems, access and system damage. Testing on the modified login system from the Laravel 7 framework this study has been successful to map users, their access levels, block SQL injection and secure data access accordingly

Abstract

CV Fenny is a business or a trading business in the field of food or daily necessities. CV information system. Fenny still uses a manual system, inversely proportional to increase the number of customers and increasing sales turnover. Therefore, as a consequence, the information needs cannot or is not fulfilled and result in an increase in the performance of CV employees. Fenny is difficult to achieve in meeting consumer demand. Because the data collection was not structured and found some duplicate data. Storing and retrieval of transaction data have not been neatly arranged, because it only relies on a manual recording, and the storage is still using file cabinets which result in the accumulation of documents, and as a result, it is difficult to recover old transaction data if needed. The process of making sales data reports less accurate, fast, and perfect because you have to collect all the transactions that occur first, as a result, it will take longer. The method used in designing the sales and information system CV. Fenny uses the waterfall method. Making a sales system CV. Fenny, is expected to solve existing constraints, simplify, speed up the sales system, and hopefully increase the profit from selling goods on the CV. Fenny.

Abstract

Web-based document editing is a system for making scientific papers without having to adjust the format of writing scientific papers. Where in this system has provided a framework for entering journal contents. Journal article creation must follow the format already in place in the organization, such as font size, edge size, and so on. Often in writing journals, writers experience difficulties or constraints in the format of writing, so they often experience errors in writing journal articles. For this reason, it is necessary to have a standard web journal writing program, which provides a framework for the format of journal writing. The process carried out in designing this application is  by looking  at  the guidelines  for  journal  manuscript  writing, with  these guidelines the writer can know how the journal format will be translated into a program script. The purpose of this research is to design a standard web program for editing documents in journals and to assist journal authors / journal authors in making scientific papers online. In this research, the writer made a document editing system for scientific journal writing format using PHP and MySQL in the application system. Where in the system designed the author only includes the entries of each input in the journal framework. In this system all the input that is filled in is stored in a database with different tables. And when the author sees the contents of the journal, the display on the journal contents automatically matches the journal template.

Abstract

Android is the most popular OS today, many of which use android as a learning medium, knowledge and tools for calculating examples such as making electronic component calculators that can help repair technicians of electronic devices. In this study, the authors made an electronic component calculator application that can calculate a component value by reading the component codes carried out by the application. In making this application using Android Studio tools to create the source code. Adobe Photoshop is of course for the design. Of course, this is in line with the purpose of the author's research. The results of research by electronic device repair technicians and students are greatly helped by this application.
