The rapid advancement of digital communication technologies has heightened the demand for robust data security methods, particularly for safeguarding sensitive information against cyber threats. Steganography, the art of concealing data within digital media, offers an effective means of securing communication by masking the very existence of hidden messages. This study evaluates the Two Least Significant Bits (2LSB) method as an enhancement to the conventional Least Significant Bit (LSB) technique, focusing on improving storage capacity and resistance to detection. The research employs a quantitative methodology, conducting experiments to analyze the impact of data embedding on image quality using metrics such as Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR). Data embedding was tested on images of varying sizes and resolutions, with results compared before and after embedding. The study also evaluates the system’s tolerance to compression and robustness against steganalysis attacks, such as histogram analysis and noise detection. The results demonstrate that the 2LSB method significantly enhances storage capacity while maintaining high image quality. For instance, PSNR values remained above 40 dB across all tested images, indicating minimal visual distortion. The method also showed resilience to lossless compression formats such as PNG, with minimal impact on data integrity. However, lossy compression formats like JPEG posed challenges in maintaining the embedded data. The MSE values before and after embedding were minor, ensuring that the hidden data remained undetectable under standard analysis. This research contributes to developing more efficient and secure steganography techniques, providing practical applications in protecting sensitive data during transmission. The findings underline the 2LSB method's potential as a viable solution for digital security, balancing enhanced storage capacity with robust resistance to detection. Future work should further explore integrating advanced encryption with 2LSB to strengthen data protection in diverse digital environments

Problems faced by mosque youth service partners include: Not all MSMEs have good access to stable internet. This can hinder their ability to manage their online store, update inventory, or interact with customers efficiently. Many MSMEs have limitations in terms of human resources, technical expertise and technological infrastructure. This makes it difficult for them to manage the e-commerce platform effectively. Packaging and labels must match the product itself, both in terms of size, shape and other physical characteristics. Finding practical and attractive packaging that also protects the product well can be a challenge. Good packaging design can sometimes involve additional costs, such as graphic designer fees or custom packaging production. For MSMEs with limited budgets, this can be an obstacle.
This service activity was carried out in the Gunungpati Village hall on Jalan Magersari Gunungpati, Gunungpati District, Semarang, which included lectures, training and direct mentoring and step-by-step direct assistance. This activity was carried out over 2 days and was attended by 17 participants from MSME actors in the Gunungpati Village area in Gunungpati District, Semarang City and guided by 7 presenters/lecturers from the University of Computer Science and Technology.
Training activities along with assistance on product packaging labeling received a good response from partners and participants. Partners, in this case, the Gunungpati Village, appreciates this activity because it can help in developing the MSMEs of its fostered partners in increasing their knowledge and skills regarding labeling.
