Abstract

This study starts from making observations or collecting data about the condition of computer networks at the Faculties in the distribution of bandwidth and autentication. At the testing stage, it uses a simulation with 3 users in infrastructure and ad­hoc. Hotspot user authentication used to restrict the number of users that use wireless facilities. Speed Internet access becomes faster with the fair distribution of bandwidth for users. Mikrotik is a reliable operating system, not only because safety data are difficult to penetrate, but also router can be used for offices, cafes etc. With the hotspot usage management, it will speed up users to conduct their activities with a large bandwidth which is large enough.

Nowadays, the campus map in Muhammadiyah University of Surakarta is made from paper as a conventional map. It can not helps people to find a location and its description in easier way. For example, when we want to find the location of Student Extracuricular Group (UKM), faculties, canteen and the other places, we must have a map and search it manually. This research is aimed to make a digital map aplication to help the searching of locations in Muhammadiyah University of Surakarta. It also provides the description or information of a location in detail. Every registered member can upload the data to give the description of the given location. This digital map application will help the administrator in the data editing, because it can be done in everytime and everywhere. The type of the study is qualitative research. The data collections are done with interview to Muhammadiyah University of Surakarta’s students and direct observation to the Student Extracuricular Group (UKM) locations. After gets the data, the writer processes the data with Macromedia Flash 8, PHP software and MySQL database. The trial can be done by localhost server or internet acces. This research have succeeded in making digital map application which can be accessed by Local Area Network (LAN) and internet as the advantage.

Abstract

In line with the growing use of computers in medicine, the perceived needs of the image data in digital format. The digital format allows for storage of image data in the computer and processes for further image analysis. Available images today are analog images, the necessary process of digitization with digitizer equipment.The image obtained is not necessarily as expected. Supporting equipment, film, and the scanner has a part in creating the image.Quality of image enhancement is needed to create a quality image allows physicians in diagnosing and minimize the possibility of error analysis. One of the digital image processing techniques is improving the quality of the image (image enhancement). This is done to obtain a good image after a loss of quality during the process of digitizing the image. Image enhancement techniques are divided into two parts. They are spatial domain and frequency domain. This study uses the spatial domain technique which consists of two stages, such as point operation and mask operation. Image experiments performed with several samples such as thorak, collar bone, bone, body tissue, and the image of the hand. Some sample images have different characteristics but the process of image enhancement have in common that will be improving the image brightness. Combining the methods of image enhancement performed to get the final digital image that has good qualities, such as histogram function,sharpen function, and continued with the function of a negative image. The final result of the digital image after processing showed that the better image quality.
