Pertukaran informasi pada saat ini sangat mudah untuk dilakukan. Bentuk informasidigital yang dapat ditukar berupa data text, gambar, gambar bergerak dan suara. Seiring denganperkembangan tersebut, tingkat keamanan atau kerahasiaan data juga semakin lemah. Orangdapat dengan mudahnya melakukan "pencurian" data, untuk itu diperlukan teknik untukmenyembunyikan data, dengan harapan agar data yang sifatnya rahasia tidak diketahui olehorang yang tidak berkepentingan. Pada kasus ini data yang akan disembunyikan adalah data textatau pesan text, sebagai tempat untuk menyembunyikan pesan ini adalah file audio denganformat wav. Metode untuk menyembunyikan pesan menggunakan metode Least SignificantBit, cara kerja dari metode ini yaitu dengan mengubah nilai bilbit terakhir dari data WAVdengan data pesan rahasia. Hasil penyembunyian pesan menggunakan metode LSB pada fileWAV tidakberpengaruh sec ara signiJicantterhadap kualitas file WAV.

The problem addressed in this research is how to predict the winner of football match with various criteria. The problem will be solved using Analytic Hierarchy Process (AHP) method. The AHP method that implemented to solve the problems will run two analysis to get an alternative solution. The first AHP method is criteria analysis, in order to get priority vector value. In criteria analysis, to know the consistency of criteria value filling, CR < 10%. If known that criteria value filling not consistant, the process must be repeated until CR < 10%. Then continue with alternate analysis to get global priority vector value wich is AHP solution. The accuration of this system is close to 80% compare with the real condition.

User Interface (Interface) is a visual display that can bridge the system or application with the user. Therefore, the interface is an important thing for a system or application as it looks seen by the user. This interface is implemented on websites that are built easily for users. The website that was built aims to build user understanding that cultural preservation is important. The preservation of this culture is the Toba Batak Ulos Fabric from Medan, North Sumatra. Ulos cloth is a characteristic of the Batak tribe and has been continuously developed for generations. Therefore, the author built an interface website to help digitally preserve Ulos Fabrics that can be accessed by everyone. In this study, the website was built using the Goal- Directed Design method which consisted of 6 stages, namely Research, Modeling, Requirements, Framework Definition, Refinement, and Development Support. After completing the 6 stages, the website that was built was tested using the Usability Testing and System Usability Scale (SUS) methods. Usability Testing uses 2 aspects, namely Task Success and Time On Task, while the System Usability Scale uses questionnaires to 50 respondents. The final result of the test experienced a significant increase that the usability of the website was aboveaverage.

The interface is a very important thing for a system or application, because it connects users directly with technology. An easy interface makes users skilled when using a system or application, especially for the elderly so as not to become a marginalized group in the technology era. mobile JKN is an application developed and managed by the government that focuses on public services, namely BPJS which is converted from a system of administrative activities carried out at branch or central offices into an application. This study focuses on designing the JKN mo-bile application interface for the elderly with a case study that refers to the JKN v2.11.0 mobile application interface, where based on usability results that have been carried out for the elderly, mobile JKN is not yet user friendly such as the interface is too complex, icons and writing that is too small, and navigation in depth so that the application interface is not optimal for the elderly. Therefore, recommendations for the design of the JKN mobile application interface were made according to the characteristics of the elderly using expert guidelines so as to produce an interface with gridview and listview menu layout with dropdowns; bold and capital letters with sizes 16 and 20 sp; using 3-dimensional icons with 90 dp cardview description. Usability testing used in this study uses the principles of ISO 9241-11. The result showed a significant increase for effectiveness, efficiency as well as satisfaction.

Having an ideal body weight is a wish and dream for everyone. The ideal body weight is the body shape desired by every group, both women and men, both at old and young ages. Unhealthy eating patterns and consumption of foods that are difficult to digest will make the body overweight, due to excessive accumulation of calories. Being overweight (obese) should not be ignored, because it can have a negative impact on the health of the body. The design of a calorie control application design can help users find out the number of calories needed for the body. The user centered design method is used as a reference in creating application interfaces that suit user needs, so that users can interact quickly and easily to use this application interface. In this study, usability testing was carried out by paying attention to 3 aspects, namely effectiveness, efficiency, and satisfaction according to ISO-9241-11 standards, which resulted in an effectiveness value of 97.65%, 68% efficiency, and 86.57% satisfaction. After obtaining the values of these 3 aspects, a simplification is carried out using the single usability metric method, which produces a value of 84,07%. So it can be concluded that the purpose of the application being tested has been fulfilled.
