The purpose of this study is to generate watermarking of an input image. The watermarking process will begin with the process of reading color image pixels. After that, the process will be continued by calculating the step message value inserted and inserting all the necessary values in the watermarking checking process. In the event of an attack, then at the time of watermarking formation, a specific noise value (randomly generated) will be calculated to be inserted into the image. After the process of watermarking formation, then the process can be continued with checking watermarking and extracting messages.

“…Digital Imaging ini merupakan proses pengeditan atau manipulasi pada gambar (Suheryadi 2017) agar membuat tampilan gambar menjadi lebih indah. 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.…”

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.

“…To validate digital works of image ownership, you can apply a blind watermarking scheme as was done (Harahap, Hannan Budiman & Novamizanti, 2016), (Suheryadi, 2017) and (Febriani, 2016) in their research can prove that the resulting image is still original or has been modified . In addition to using blind watermarking, in a study conducted by (Rosadi, Informasi, & Sti, 2018) and (Hardianto, Novamizanti, & Prasasti, 2017) hybrid compression was used to secure medical images.…”

“…For a home industry usually has many batik designs produced, but this design can be duplicated because there is no system that can help to secure the design as an identifier from the initial design owner as in the research conducted (Saputra, Fauziah, & Hayati, 2020) and (Zulfan & Muharar, 2016) and (Zhou, Bai, & Wang, 2015). The existence of a compression system using watermarking allows a product design to be secured as was done in research , (Suheryadi, 2017) and (Ardiansyah et al, 2017) to be able to find out the owner of the initial design of the product so that Home industry craftsmen will feel the results of their work and can also continue to improve their creative works.…”

Safeguarding copyright on traditional batik works is very important to prevent duplication of Indonesian cultural products. The ease of duplicating, especially in batik designs, causes frequent violations of the design's copyright. Especially with the rise of online commerce today, it is easier for everyone to use other people's products and copy other people's products. This will not happen if there is already a system that can be used to secure the design work. For this reason, it is important to develop methods that can be used to secure traditional batik works, especially Surakarta. Based on these problems, a research was conducted on the application of image watermarking techniques that are resistant to changes generated by image processing in the form of compression. The method used to secure Surakarta batik works is compression using wavelet transformation. The aim is to develop a batik design security system method using the watermarking method. The steps taken started with taking photos of batik designs and the designer's name, photos in the form of images followed by the embedding process using the watermarking method. The watermarking method used is the DWT method. After encryption, identification is carried out to determine the level of errors that occur. The results of testing 323 batik image data in this study obtained an average mse level = 0.00000065 and an average psnr result = 188.471186102179. From the results of this study, it was found that the development of methods that can be used to secure batik products by using the watermarking method.
