Abstrak Pesatnya perkembangan teknologi, berdampak negatif pada kerahasiaan dan keamanan informasi yang dimiliki pengguna saat melakukan transmisi informasi. Sekiranya diperlukan sistem untuk mencegah bocornya informasi. Salah satu cara menjaga kerahasiaan informasi adalah menggunakan teknik steganografi, dimana informasi disisipkan pada media pembawa dilakukan transmisi. Namun, umumnya penggunaan teknik steganografi saat ini membuat teknik tersebut tidak terlalu efektif. Agar masalah itu dapat diatasi, maka penulis bertujuan melakukan penelitian untuk menggabungkan teknik steganografi dengan teknik kriptografi. Pada penelitian ini akan dilakukan perancangan dan analisis steganografi video berbasis SWT menggunakan teknik SVD dan algoritma kriptografi RSA. Proses steganografi sendiri menggunakan Stationary Wavelet Transform (SWT) dan singular Value Decomposition (SVD) sebagai ruang penyisipan informasi. Proses kriptografi sendiri menggunakan algoritma RSA untuk chipering informasi teks. Sebagai perbandingan, akan disematkan teknik kompresi Compressive Sensing (CS) untuk memperkecil ukuran informasi. Berdasarkan hasil pengujian yang telah dilakukan, diperoleh parameter sistem yang paling optimal antara lain P = 13, Q = 17, layer RGB merah, subband LL, mother wavelet db3, dan frame ke-11 dengan raihan persentase BER sebesar 0%, persentase CER sebesar 0%, dan nilai PSNR 87,033. Sedangkan raihan untuk sistem dengan kompresi mendapatkan persentase BER sebesar 6,956%, persentase CER sebesar 34,783% dan nilai PSNR sebesar 92,673 dB. Kata Kunci: Steganografi, Kriftografi, RSA, SVD-CS Abstract Technological developments have a negative impact on security of information owned by users when transmitting information. If a system is needed to prevent information leakage. One way to maintain the confidentiality of information is to use steganography technique, where information is inserted into the carrier medium for transmission. However, generally the current use of steganography techniques makes these techniques uneffective. This problem can be overcome, the author aims to conduct research to combine steganography with cryptographic. In this research, SWT-based video steganography will be designed and analyzed using SVD and RSA cryptographic algorithm. Steganography process uses Stationary Wavelet Transform and singular Value Decomposition as information insertion space. Cryptographic process uses the RSA algorithm for ciphering text information. For comparison, Compressive Sensing compression will be embedded to reduce size of information. Based on the results of the tests, the most optimal system parameters obtained P = 13, Q = 17, red RGB layer, LL subband, mother wavelet db3, and 11th frame with BER percentage achievement of 0%, CER percentage of 0 %, and the PSNR value is 87,033. While the achievement for the compressed system gets BER percentage of 6.956%, CER percentage of 34.783% and PSNR value of 92.673 dB. Keywords: Steganography, Cryptography, RSA, SVD-CS.References
