Abstract

Security and confidentiality of data transmission are two important aspects in the era of openness to data access and information. One way to secure the data transmission is using steganography. In this research, the method used is End Of File (EOF) and used image as the medium. The message is hidden by inserting it in the end of the line image file. The media for hiding the message is in the form of .jpg and the output is in the form of .png. Inputting message is done manually. Testing have  been conducted on 5 types of images with different resolutions with a number of different messages characters which are 10, 100, and 1000 characters. The results show that the method of End Of File (EOF) successfully used to hide message in the media image and to take back the message that has been inserted. The image size and the number of characters used affects the processing time for embedding and extracting. Cropping, contrasting, and brightness on stego image are conducted to analyze the resilience of the message inserted. The results show that the stego image manipulations are sensitive or resistant to the manipulation that makes the message becomes corrupted and are not recommended in manipulating stego image.Keywords : embed, End Of File (EOF), extract, image, steganography, stego Image

Abstract

AbstractBesides providing the education, a lecturer has an obligation to carry out the research and dedication for society. Research and dedication were one of requirements to increase the lecturers’ functional position and as an assessment reference of department accreditation. Data processing of lecturers’ research and dedication in Computer Science Department used a spreadsheet. The use of spreadsheets thas been able to process the data of the research and dedication well, but it less according to time and resource efficiency. This study was conducted to develop information systems of lecturers’ research and dedication in Computer Science Department as a management tool of department in data processing of lecturers’ research and dedication. System development method that is used is the Rational Unified Process (RUP). RUP is a collection of best practices from software development industry. RUP has six mains workflow those are business modeling, requirements, analysis and design, implementation, testing, and deployment. Lecturers’ research and dedication information systems in Computer Science Department has been developed using the RUP. RUP method provided flexibility to the programmer in develeoping software.Keywords: dedication, information systems, lecturer, research, rup.

Abstract

Geographic Information Systems (GIS) is an information system which is used to input, process and generate geographically or geospatial referenced data to support the decision making in a planning. This technology can be used on an Android-based smartphone. Internet, accelerometer, digital maps and GPS (Global Positioning System) on Android can be integrated so that GIS can be implemented. In this study, GIS technology is implemented to detect and find the location of health care providers in city of Bandar Lampung. This application is designed and implemented by using Java programming language and Google Maps API to show the location of health care providers. Testing phase by using Equivalence Partitioning method indicates that the function of the application has been running in accordance with the analysis. Keywords : Android, Application, Geographic Information System, Healthcare Provider, Map.

Abstract

AbstractThe condition of a location can be seen and known through a map. Even though The University of Lampung has a campus map in a form of paper, still the data displayed in this form is very limited. This map has not been used to display information related to the existing facilities and personnel of the University of Lampung. This research design a web based Geographic Information System (GIS) focusing on information of lecturer and his/her department unit. This web based GIS can be used as a tool for visitors and academics to obtain information on faculty unit, building, facilities, as well as the map of the University of Lampung. This web based GIS is developed using several open source software which are QuantumGIS, MapServer, Pmapper Framework and MySQL database. Pmapper Framework increase  speed, accuracy, convenience and consistency in the development of applications that use MapServer.Keywords : facilities, map, MapServer, Pmapper framework, The University of Lampung, web based GIS.

Abstract

Markerless Augmented Reality (AR) is a term for an environment that combines real world and the virtual world, where objects in the real world can be recognized through the position, direction and location. Markerless AR technology can be used to interactively visualize information, especially when the technology is combined with a mobile communication device such as a smartphone that has the Android operating system. Camera features, internet, accelerometer, digital maps and GPS (Global Positioning System) on Android devices can be integrated so that AR technology can be implemented. In this study, Markerless AR technology is implemented in the Faculty of Mathematics and Natural Science (Science) University of Lampung buildings. The aim of this study is to create an application that provides information about the buildings, it is show Faculty maps and information about the Natural Sciences accessible via Android smartphones. This application is designed and then implemented using the Java programming language for Android and BeyondAR framework support to detect and display the AR object and the Google Maps API to display a map of the Science Faculty. The results of data test using Equivalence Partitioning test shown the application functionate well according to the analysis. In addition, based on questionnaire data, that the application is a user friendly application (with an average value of 4.31 / very good), and interactive (with an average value of 4.23 / good).Keywords: Android, Application, ARMIPA, Augmented Reality, Maps, Markerless Augmented Reality

Abstract

Biology is part of science that have special characteristics different from other sciences, in terms of objects, issues and methods as well as having many terms and have the object form of the Kingdom (kingdom): Animalia (animal’s world), Plantae (plant’s world), Monera, Protista, and Fungi. Object numbering thousands of types into its own difficulties to learn it. One way to make it easier to learn it is grouping or classification of organism is called Taxonomy and the scientific name is called Binomial Nomenclature. In this study, to learn the classification and scientific nomenclature, then created taxonomy’s application based on Android, which aims to facilitate students in classifying organism consist of Kingdom, Sub Kingdom, Super Division, Division, class, Sub class, Ordo, Family, Genus, and species. This application is designed and then implemented using the Java programming language for Android, MySQL and Web Server to manipulate the data that is needed, and updates the database periodically. The results of data test using Equivalence Partitioning test shown the application functionate well according to the analysis. In addition, based on questionnaire data, that the application is a user friendly application (with an average value of 4,17 / good), and interactive (with an average value of 4,08 / good).Keywords : Android, Application, Binomial Nomenclature, Taxonomy.
