Abstract

Behavior of sexual deviation is an unacceptable sexual behavior among the public. The lack of knowledge and the many obstacles to obtain information about early detection and community independence about sexual deviation and ignorance of the community in dealing with sexual deviation is also a factor not handled early. Forward chaining, consultation begins with a search of the premise or input data in the form of symptoms to the conclusion that is the conclusion of the type of deviation behavior as well as the solution. From the above problems will be built Web-based system that serves to detect the beginning independently of the perceived disorders that can be accessed with an extensive lap and time is not limited.The system is built using PHP and MySQL programming as the database. The method used for forwarding is forward chaining. While the results of the diagnosis will inform about the diagnosis of the list of symptoms included, information on the results of the rules of the disorder suffered and information about the possibility of handling can be done.Black box testing techniques are emphasized on data entry, output data, system functions, performance, and initialization in the system. While testing the alpha test is done by inviting 10 respondents testing is emphasized on the interface, dialogue, and information generated. From the results of testing the alpha test shows that the system created has been running well and produce information that is accurate, and easy to understand.

Abstract

LazisMu Umbulharjo has quite a number of social activities, including raising funds through charity boxes to several points, such as places of worship, community services, and Muhammadiyah residents in the Umbulharjo area and its surroundings. LazisMu Umbulharjo has managed at least 900 charity boxes spread across 7 sub-districts of the Umbulharjo area and also outside the Umbulharjo area. Currently, the courier who shuttles the charity box is guided by the address that is packaged in a printed sheet that comes from Excel data. Some of the difficulties experienced by couriers when picking up charity boxes at these 900 points, among others, the large number of points that must be visited by one courier. Couriers have difficulty memorizing the positions of the hundreds of charity boxes. Courier difficulties and often missed on the way to the points of the charity box. Problems occur if the staff replaces them with new ones so that adjustments are made from scratch again in learning the pick-up location. This research was conducted based on the stages in the User Centered Design (UCD) process. Plan the human centered process, specify the context of use, specify user and organizational requirements, product design solutions, and evaluate design against user requirements. Research has produced a prototype of the LazisMu Umbulharjo application with the main features of a dashboard for managing data and general information and managing a charity box. User management, charity box location management, and finally the determination of the pick-up route. The application prototype has been tested for usability and calculated using the System Usability Scale (SUS) with an average score of 82. Based on this score, the prototype of the LazisMu Umbulharjo application can be accepted by users (ACCEPTABLE) with grade A and gets an EXCELLENT level

Abstract

This research aims to secure text data by combining steganography and cryptography. The Pixel Value Differencing (PVD) method allows for higher data insertion capacity with minimal distortion, thereby increasing resistance to steganalysis. However, the PVD steganography method is vulnerable to variation in image areas and to the accuracy of Pixel Difference Histogram (PDH) analysis. In addition, this method is susceptible to statistical tools such as the chi-square and RS, which can be used to analyze the distribution of pixel value differences, allowing data to be detected. To address the limitations of the PVD method, we employed a cryptographic technique called XOR-VLSB, which combines XOR as the primary encryption method, Vigenère Cipher for key generation, and Least Significant Bit (LSB) for key embedding. The results showed that the fully encrypted data could be recovered and had good image quality, as indicated by the metric results, which included a low MSE value, a PSNR above 35 dB, and an SSIM value close to 1. In this study, the process of encrypting text data still uses a simple encryption algorithm, namely XOR. Future research may involve replacing cryptographic algorithms with AES, which offers stronger protection and better resistance to advanced security threats.
