Abstract
Seiring dengan perkembangan teknologi yang semakin canggih membuat segala macam sistem keamanan belum dapat dikatakan aman dari pihak ketiga. Keamanan data menjadi salah satu subjek utama yang membutuhkan perhatian agar terhindar dari pencurian data. Steganografi merupakan salah satu bentuk penanganan dalam masalah pencurian data yang bekerja dengan cara menyisipkan suatu data rahasia kedalam suatu media, umumnya media audio. Beberapa penelitian sebelumnya telah memberikan banyak gambaran terkait metode steganografi beserta peningkatan yang dilakukan. Namun, nilai yang dihasilkan masih tergolong rendah jika dibandingkan dengan beberapa metode terkait. Kelemahan yang sering terjadi dalam metode steganografi adalah rendahnya kualitas dan kapasitas yang dihasilkan. Penelitian ini mengusulkan metode yang memanfaatkan nilai interpolasi sampel dan fuzzifikasi untuk meningkatkan kapasitas penyisipan, serta adanya penambahan metode smooth distribution untuk memberikan nilai kualitas yang sebaik mungkin. Hasil menunjukkan adanya peningkatan kualitas dan kapasitas jika dihitung dengan Peak Signal to Noise Ratio (PSNR) sebesar 0.0053 dB dan 0.005 bit dengan metode terkait pada penelitian sebelumnya.

Along with the development of increasingly sophisticated technology, all kinds of security systems cannot be said to be safe from third parties. Data security is one of the main subjects that requires attention in order to avoid data theft. Steganography is a form of handling the problem of data theft which works by inserting confidential data into a media, generally audio media. Several previous studies have provided many descriptions regarding the steganography method along with the improvements made. However, the resulting value is still relatively low when compared to several related methods. Weaknesses that often occur in steganographic methods are the low quality and capacity produced. This study proposes a method that utilizes sample interpolation and fuzzification values to increase insertion capacity, as well as the addition of a smooth distribution method to provide the best possible quality value. The results show an increase in quality and capacity when calculated with a Peak Signal to Noise Ratio (PSNR) of 0.0053 dB and 0.005 bit with the method related to previous research.
