Abstrak

Abstrak Bahasa Indonesia : Keamanan merupakan hal terpenting dalam pengiriman suatu data digital. Dalam hal ini steganografi merupakan seni untuk menyembunyikan pesan rahasia kedalam pesan lainnya sedemikian rupa sehingga orang lain tidak menyadari adanya suatu sesuatu di dalam pesan tersebut. Dalam penelitian ini, peneliti membangun sistem steganografi digital menggunakan metode Adaptive Minimum - Error Least Significant Bit Replacement (AMELSBR) berbasis web, dengan media penampung berupa gambar dengan format file (.jpg) sebagai input (cover), gambar dengan jenis file (.png) sebagai output (stego image) serta data yang dapat disisipkan berupa berkas dengan format file (.txt). Metode AMELSBR mempunyai tahap-tahap yang harus dilakukan untuk menyisipkan suatu data, yaitu Capacity Evaluation, Minimum – Error Replacement dan Error Diffusion. Kesimpulan yang didapat dari penelitian ini adalah metode AMELSBR berhasil menyembunyikan berkas dan mengembalikan berkas yang telah disisipi sebelumnya tanpa menimbulkan distorsi (noise) yang berlebihan pada stego image. Metode AMELSBR mempunyai kemungkinan pengembalian berkas paling banyak terhadap manipulasi gambar berupa perubahan Brightness dan Contrast pada gambar dengan warna dominan hitam (rgb(0,0,0)) dan warna dominan putih (rgb(255,255,255)) serta tahan terhadap pemotongan (crop) gambar yang dilakukan pada bagian kanan dan bawah gambar dengan skala pemotongan tertentu. Abstract Bahasa Inggris : Security is paramount in digital data transmission. In this case steganography is an art for hiding a secret message into other messages such a way that others are not aware the existence of something in the message. In this study, researchers built a digital steganography system using web-based Adaptive Minimum - Error Least Significant Bit Replacement (AMELSBR) methods, with media placeholders in the form of an image with file format (.jpg) as input (cover), the picture with the type of file (.png ) as output (stego image) and data that can be inserted in the form of a file with file format (.txt). AMELSBR method has some steps that must be done to insert the data, namely the Capacity Evaluation, Minimum - Error Replacement and Error Diffusion. The conclusion of this study is AMELSBR method managed to hide files and restore files that have been previously inserted without causing excessive distortion (noise) in stego image. The AMELSBR method has a possibility of returning most files to image manipulation such as the change of image Brightness and Contrast with the black color dominant (rgb(0,0,0)), white color dominant (rgb(255,255,255)) and resistant to image cutting (crop) performed on the right and bottom of the image with a certain scale cuts.
