Abstract

Testing is needed on the application to find out whether the application is a bug or needs to be improved to make it better. The black-box testing method has been widely used by researchers to test application suitability. The application being tested is a contribution system application consisting of menus that the administrator wants to enter. When the testing process produces bugs that were previously unknown, then the test is considered a good test. The purpose of application testing is to see if the program performs every function we expect without looking at the source code of the software's functions. The type of black-box testing procedure used in this study is equivalence partitioning. The equivalence division process is a test that starts with filling in each form on each input menu, the content to be tested starts with valid or invalid.

Abstract

Nowadays, computers have an important role in human life. Because computers really help humansin carrying out tasks through the applications and features available according to human needs. Most of the people who have a business doing all their activities are more computerized on a regular basis for reasonsof time, less risk and faster decisions than without a computer. For this reason, the purpose of this study isresearch aims to evaluate the effectiveness of using Selenium in functional testing of web-based point of sale (POS) application using the blackbox method. Selenium is an automated testing tool used to test web applications by recording and playing back user actions on the browser. The blackbox method is used to examine the application's functions from the user's point of view without checking the implementation details of the source code or the internal structure of the application. This research uses a web-based POS application as a case study and performs functional testing using the blackbox method with and without using Selenium. The test results show that using Selenium in functional testing of web-based POS application with blackbox method can improve the effectiveness and efficiency of testing, as well as ensure that the application functions properly and meets the user's needs. This research contributes to the development of web-based POS application testing methods using automated tools such as Selenium to improve the effectiveness and efficiency of testing.

Abstract

This research focuses on the issues of data security and document management at SMK Teknologi Informatika YPML, an educational institution that manages a large number of educational documents. Currently, this institution does not use an encryption system application, which potentially leads to data leaks and other security issues. To address this problem, this research designed an encryption and decryption system application to protect documents and files from unauthorized access. This application is designed by implementing the AES (Rijndael) encryption algorithm capable of encrypting up to 256-bit, so only individuals who have the encryption key can open the document. This research hopes to improve data security and document management efficiency in educational institutions.

Abstract

Face Detection is an important part of digital image processing to determine the location, size and number of faces in an image. Face detection is the initial stage in a facial recognition system that is used for personal identification, human-computer interaction, monitoring systems, criminal law and so on. This study presents face detection with skin color segmentation & template matching methods. The first step is to make a skin color model by transforming into YCbCr and then find the average number of facial skin colors. Next build a Gaussian distribution for the chroma chart which shows the possible skin colors. Adaptive thresholding is used to emphasize skin and non-skin areas presented in binary images. Segmentation of skin areas is done by labeling. Face candidates are obtained from calculating the number of holes in the segmented skin area, calculating the face width-to-height ratio and matching with the face template (template matcing). The centroid of the detected face is calculated and a marker is placed at the centroid of the face in the image. Based on trials with the Matlab 2011 tool with datasets taken from FDDB (Face Detection Data Set and Benchmark), the detection accuracy obtained from trials on 76 images with varied backgrounds and lighting levels reached 81.58%.
