The importance of introducing knowledge about dinosaurs as part of prehistoric life history to children from an early age cannot be overlooked. This understanding equips them with a foundational perspective on Earth's evolution and ancient biodiversity. Unfortunately, conventional teaching methods often fail to capture children's interest, appearing monotonous and lacking immersive learning experiences. This limits their potential to deeply explore and appreciate the wonders of the prehistoric world. Recognizing these limitations, an innovative study was conducted to develop an educational game based on multimedia technology, specifically designed to address these challenges. The primary objective of this game is to enable users—especially children—to learn about various types of dinosaurs through a first-person perspective within a detailed and interactive virtual museum environment. The development method used in this project is the Multimedia Development Life Cycle (MDLC), a systematic framework consisting of six essential stages: concept, design, material collection, creation, testing, and distribution. The game is carefully designed to allow users to explore the museum interactively, as if they were physically present. Users are free to interact with realistic 3D models of dinosaurs and receive educational information through easily understandable visual and audio formats. Test results show that the game successfully provides an enjoyable learning experience, significantly enhances children's interest in dinosaur history, and supports a more interactive and effective learning process. Therefore, this innovative media is expected to serve as a fresh and effective alternative for delivering educational content based on history and science to children, opening doors to deeper understanding and excitement in learning.

Implementasi dan Analisi Image Scalling Menggunakan Bilinier Interpolation pada Citra Kendaraan

Fahmi Ramadhan — 2025-09-30

Digital image processing is an essential area in computer science, particularly in manipulating and transforming images for analysis and visualization purposes. One of the fundamental techniques is image scaling, which involves enlarging or reducing the dimensions of an imageThe tests indicate that extreme downscaling leads to a significant decrease in image quality, reflected by lower PSNR and higher MSE. In contrast, moderate upscaling tends to preserve more visual quality, although it cannot enhance image details beyond the original resolution. In conclusion, the bilinear interpolation method can be effectively applied for image scaling in light to moderate scenarios. The evaluation using PSNR and MSE provides a clear quantitative insight into image degradation caused by scaling. This application can serve as a foundation for further development in image processing systems, such as object detection, vehicle classification, or visual surveillance systems.

Analisis Perbandingan Kapasitas Penyisipan Data dan Kualitas Citra Dalam Teknik Steganografi LSB dan MSB Menggunakan Peak to Signal to Noise Ratio dan Mean Squared Error

Ilham Fauzi — 2025-09-30

This study discusses a comparison between the Least Significant Bit (LSB) and Most Significant Bit (MSB) methods in digital image steganography based on image quality parameters using the Mean Squared Error (MSE) value. The LSB method embeds secret information in the least significant bits of each pixel, while the MSB method embeds information in the most significant bits. The test results show that the LSB method produces very low MSE values, ranging from 0.1 to 2, thereby maintaining image quality with changes that are visually imperceptible. In contrast, the MSB method produces high MSE values, reaching 40 and above, indicating significant pixel intensity changes and a considerable decline in image quality. Based on these results, it can be concluded that the LSB method is more effective and secure for hiding data in digital images, as it preserves visual quality and is difficult to detect. Meanwhile, the MSB method is less recommended due to its susceptibility to detection and noticeable degradation of image quality.
