The research was conducted in the field of steganography. Discrete Cosine Transform (DCT) is a method used in the insertion technique. The results of steganography have problems if they look blurry, have low levels of similarity and high error values. One way to solve this problem is by proposing image interpolation. The interpolation method consists of various kinds and gives each other advantages. This study intends to compare three kinds of interpolation techniques to find the best one. The three interpolation techniques are bilinear, nearest neighbor, and spline. The method used in this research is experimental. Images with extension formats * .tif, * .png, and * .bmp with dimensions of 512x512 px are interpolated by scaling 1.5, 2, and 4. The results of the interpolation process are used to insert messages in * .txt format of 157 bytes with discrete cosines transform (DCT). The image quality of the message insertion is measured by the MSE and PSNR values. The result of the message insertion test shows that the value of the image quality is directly proportional, meaning that if the condition of the message size is fixed and the cover dimensions are greater, the MSE value will be smaller and the PSNR value will be greater. Images with * .tif and * .bmp extension formats have good stability, * .png images vary in size. The smallest error value test results were obtained in the spline interpolation technique and this method when compared to the other two techniques had the lowest average MSE value of 8.221 and the PSNR value of 40,301 dB.

“…Namun disisi lain karena kemudahan untuk di rubah dan dimanupulasi, tak heran banyak disalah gunakan oleh orang yang tidak bertanggung jawab sehingga digital imaging ini sering di padukan dengan metode-metode dalam sitem keamanan, seperti steganografi yang merupakan bentuk pengamanan pesan pada sebuah media. dimana pesan disisipkan pada sebuah gambar digital (Garno and Adam 2019). Selain itu digital imaging juga dimanfaatkan sebagai analisis gambar digital dalam suatu objek yang melibatkan pixel warna serta halhal yang berhubungan dengan kualitas gambar (V. Kusumah, C.Sawung 2015).…”

Banyak sector yang merasakan dampak pandemi global (covid-19) yang sudah terjadi hampir satu tahun belakangan ini. Pandemi global yang dirasakan hampir semua negara ini, mengakibatkan perekonomian menjadi lumpuh. Banyak perusahaan yang terpaksa harus gulung tikar, yang otomatis membuat semakin banyaknya pengangguran. Berdasarkan pengamatan yang dilakukan secara tentative selama masa pandemic ini, orang semakin banyak berjualan online. Berjualan secara online menjadi pilihan, karena selain tidak membutuhkan modal yang banyak, juga bisa dipasarkan seluas-luasnya. beberapa produk yang dijual baik produk jadi maupun produk olahan, sudah memiliki tampilan yang baik, karena proses pengambilan gambar dan editing dilakukan oleh tenaga professional. Namun, berbeda dengan pelaku usaha yang baru terjun dalam jual beli online yang memiliki modal seadanya tentu tidak bisa menyewa tenaga professional untuk menampilkan keindahan dan estetika dari produk yang akan dijual. Oleh karena itulah di berikan pelatihan Digital Imaging ini dilakukan untuk membantu pelaku Usaha Mikro Kecil Menengah (UMKM) dalam editing produk, sehingga produk yang dijual dapat bersaing. Editing produk yang dilakukan pun cukup mudah, hanya dengan memaksimalkan Smart Phone dengan mengunduh beberapa aplikasi yang mendukung dalam proses editing ini.

Abstract: Many sectors have felt the impact of the global pandemic (Covid-19) which has occurred for almost a year. The global pandemic that is being felt by almost all of these countries has caused the economy to become paralyzed. Many companies have gone out of business, which automatically creates more unemployment. Based on observations made tentatively during this time of the pandemic, more and more people are selling online. Selling online is an option, because it doesn't require a lot of capital, it can also be marketed as widely as possible. some of the products sold, both finished products and processed products, already have a good appearance, because the shooting and editing processes are carried out by professionals. However, it is different from business actors who are new to online buying and selling who have limited capital, of course they cannot hire professionals to display the beauty and aesthetics of the products to be sold. Therefore, Digital Imaging training is provided to assist Micro, Small and Medium Enterprises (MSMEs) in editing products, so that the products sold can compete. Product editing is also quite easy, just by maximizing the Smart Phone by downloading several applications that support this editing process.

“…The steganography algorithm that is usually used is Least Significant Bit (LSB). LSB is a simple method because it only changes the value of the last bit in a message with the inserted message bit [1,[12][13][14]. However, from the simplicity and ease of the LSB algorithm, this method is vulnerable to attack if not combined with other algorithms.…”

Technological developments go hand in hand with advances in digital messaging. In protecting the confidentiality of the message, it is necessary to double secure the data. This security can be done with a combination of steganography and cryptographic techniques. Steganography algorithm which is a technique for hiding messages well, one of which is Least Significant Bit (LSB). The LSB algorithm is a simple method because it only converts the value of the last bit in a message with the inserted message bit, which is a convenience of the LSB algorithm, but it becomes vulnerable to message theft attacks if not combined with other algorithms for security. So it is necessary to increase security. This research developed a combination method of LSB algorithm for steganography technique with Hill Cipher algorithm for cryptographic technique, Hill Cipher was developed with shifting (shifting) 2 (two) characters. With the development of this method, hackers will find it difficult to crack messages, and is expected to improve the performance of the algorithm in affecting image quality and travel time in running the algorithm. The results of this study will be tested using several evaluation tools MSE, PSNR, BER, CER, AE, and Entropy. With the development of this method, hackers will find it difficult to decipher messages, and from the results of this experiment has been able to improve the performance of the algorithm in maintaining image quality and can shorten travel time in running the algorithm.
