Abstract

Image watermarking is a solution to protect digital images of issues such as copyright protection, ownership, authentication, fingerprinting, and etc. Digital watermarking method using a symmetric algorithm Barni on digital images with a correlation-based method in the domain of Discrete Cosine Transform (DCT). Color images in RGB color space is transformed first into the YCbCr color space. Watermark is inserted in the array f, then the results are transformed back into RGB color space. Watermark is the real line and along the N elements are normally distributed. Watermark is inserted in the selected DCT coefficients of middle frequency sub-band to get a balance between robustness and imperceptibility. Watermark detection is done by calculating the correlation between the received image with the original watermark, and then compare it with an-value threshold. The test results are binary decision stating the image contains a watermark or not contain the watermark. The experimental results show that air-quality image watermark can not be distinguished from the original image and Barni symmetric method has proven robust against some non-malicious attacks such as JPEG compression attack, histogram equalization, gamma correction, noising, sharpening

Abstract

Abstrak: Penelitian ini memiliki kebaruan berupa penerapan algoritma Dijkstra pada Sistem Informasi Geografis (SIG) potensi desa berbasis web, yang masih jarang diterapkan pada visualisasi potensi pedesaan. Sistem dikembangkan untuk memetakan potensi Desa Karangjaladri secara akurat dan interaktif menggunakan metode Rapid Application Development (RAD). Algoritma Dijkstra digunakan untuk menentukan rute terpendek menuju lokasi potensi desa pada sektor UMKM, pariwisata, perikanan, dan pertanian. Sistem dibangun menggunakan PHP, MySQL, dan OpenStreetMap guna mendukung pengelolaan data spasial dan penyebaran informasi desa secara lebih efektif. Selain itu, sistem diharapkan dapat membantu masyarakat dan perangkat desa dalam mendukung perencanaan pembangunan yang transparan dan partisipatif. Hasil pengujian beta menggunakan Technology Acceptance Model (TAM) terhadap 134 responden menunjukkan respons sangat positif, dengan nilai Perceived Ease of Use 88,8%, Perceived Usefulness 89,55%, Attitude Toward Using 89,698%, Behavioral Intention 90,07%, dan Actual Use 89,50%.Kata kunci: Sistem Informasi Geografis, Potensi Desa, Algoritma Dijkstra, Rapid Application Development (RAD)Abstract: This research offers novelty through the implementation of the Dijkstra algorithm in a web-based Geographic Information System (GIS) for village potential mapping, which is still rarely applied in rural potential visualization. The system was developed to map the potential of Karangjaladri Village accurately and interactively using the Rapid Application Development (RAD) method. The Dijkstra algorithm was applied to determine the shortest routes to village potential locations in the sectors of MSMEs, tourism, fisheries, and agriculture. The system was built using PHP, MySQL, and OpenStreetMap to support spatial data management and information dissemination more effectively. In addition, the system is expected to assist the community and village officials in supporting transparent and participatory development planning. The beta testing results using the Technology Acceptance Model (TAM) involving 134 respondents showed very positive responses, with scores of 88.8% for Perceived Ease of Use, 89.55% for Perceived Usefulness, 89.698% for Attitude Toward Using, 90.07% for Behavioral Intention, and 89.50% for Actual Use.Keywords: Geographic Information System, Village Potential, Dijkstra Algorithm, Rapid Application Development (RAD)
