Judul: Linguistic steganography with NICETEXT method using words and sentence variations of indonesian language
Abstrak: Keamanan informasi penting dalam melindungi isi informasi dari penyalahgunaan pihak lain yang tidak berhak. Salah satu cara mengamankan informasi yaitu dengan teknik steganografi. Sistem NICETEXT yang tergolong steganografi linguistik menyamarkan keberadaan informasi dalam bentuk teks bahasa alami menggunakan kontrol bahasa yang metodenya dapat diterapkan pada bahasa alami lain dengan kesesuaian kata dan pola kalimat. Sistem NICETEXT telah diimplementasikan dalam teks Bahasa Indonesia, namun kalimat hasilnya masih terbatas satu pola kalimat. Oleh karena itu penelitian ini mencoba memproses variasi pola kalimat sehingga sistem NICETEXT dapat membangkitkan teks Bahasa Indonesia dengan pola gramatikal bervariasi. Pada penelitian ini, susunan kalimat dibangkitkan dari kombinasi seluruh unsur pengisi pola kalimat dasar. Penelitian ini berhasil menyamarkan informasi dalam teks Bahasa Indonesia dengan pola kalimat bervariasi. Namun, dari sisi semantik isi teks belum dapat dipahami dengan baik., Information security is important to protect the content of information from attacker. One of the way to secure information is by using steganography. NICETEXT system is included as one of linguistic steganography to conceal the existence of certain information in a natural language text using language control which can be applied to other natural language in words and grammar conformity. NICETEXT system has been implemented in an Indonesian text, but the resulted text still limited in one style. The objective of this research is to process various styles in order to conceal information into an Indonesian Language text with various grammatical patterns. In this research, styles are generated from a combination of all sentence pattern elements. The result of this research is information can be concealed in an Indonesian Language text with various grammatical patterns. However, from the semantic point of view, it is still difficult to understand the meaning of the text. Keywords: linguistic steganography, NICETEXT system, sentence generation

Judul: Implementation of Steganography on Text Media using Line-Shift Coding Method and Centroid Method.
Abstrak: Steganography is an information hiding technique using a certain media, such as text, sound, and images to make the message looks like another form. Nowadays, steganography is being widely used on digital document. Along with the increased use, type of attack that is used to take or damage the message done by the other parties become varies, for example, the use of scanner and printer to print a digital document with the purpose to erase the messages that have been inserted in the document. Therefore, it’s necessary that the steganography method being used has to be resistant to the process of printing and scanning, one of which is line-shift coding method. Line-shift coding method is a method that adding series bits of message in the document by moving even line in a paragraph vertically. Research was conducted to apply this method in the PostScript document. Results from this research include the estimation analysis for the size of messages that can be inserted in several different font sizes. When the font size is larger, it can be estimated that the characters of message that can be inserted are increased. In this research, line-shift coding method is proven resistant to the printing process, the difference in the quality of printing, which are fast normal (300 dpi), best (600 dpi), and maximum dpi (1200 dpi), a photocopy process up to two times, and resizing image attack to 700 * 963 pixels and up. Yet, this method has fail to pass resizing image attack up to 700 * 963 pixel, different slope angle attack and the cutting image attack.

Judul: Case Study of Gallbladder Mucocele and Treatment Used In Small Animals
Abstrak: Gallbladder mucocele (GM) is defined as distention of the gallbladder caused by an inappropriate accumulation or deposition of high concentrations of bile. The purpose of this case study is to study GM conditions in small animals and to report the clinical sign and characteristics of GM through the sonogram interpretation and blood chemistry test evaluation, and studies related to the therapy given and other treatments recommended. A 14-year-old Toy Poodle dog has been diagnosed with severe GM and cholecystitis. No pain signs were shown during the physical examination as asymptomatic is a common characteristic in the early stage of biliary related diseases. In this study Abdominal ultrasonography interpretation and blood chemistry evaluation was conducted in 2021-2022 and analyzed as a secondary data source. Ultrasonography results showed presence of hyperechoic, immobile deposits in gallbladder accompanied by wall thickening and enlarged in size, followed by a significant increase in the enzyme alkaline phosphatase (ALP). This study has summarized mainly the diagnosis and treatments of GM in small animals and suitable alternatives treatments were recommended to encounter the GM conditions in small animals. The effectiveness of combined therapy shows the positive impact on the patient, the condition of GM has been under control.
