The Contrast Limited Adaptive Histogram Equalization (CLAHE) method aims to reduce noise bydetermining the kernel matrix and work by replacing the intensity value of each input image pixel with anaverage of the kernel weighting value for each neighboring pixel and pixel itself. In the process of reducingnoise the size of the kernel is very influential in obtaining the results of image quality. The size of the kernelused by the author in this study is 5 x 5.This research has produced an application program to reduce noise using the Contrast Limited AdaptiveHistogram Equalization (CLAHE) method. The test x-ray image used in this study uses x-ray images of thoraxscal. The image is inputted and displayed on the program. Then the Contrast Limited Adaptive HistogramEqualization (CLAHE) process is carried out. Then an image will be produced as desired.

Tridharma Higher Education consisting of Education and Teaching, Research and Development, andCommunity Service is the main task of Higher Education in Indonesia in organizing National Education.To achieve these three goals, it is necessary to support the existence of an integrated information systemthat can be used to evaluate and monitor independently (self assessment report), continuous and tieredof the three tasks of the Higher Education Tridharma.STMIK Kristen Neumann Indonesia already hasa computerized system in monitoring research, education and community service activities of lecturers,but no one has overseen or monitored routinely, resulting in difficulties when searching for lecturerdata that conducts research, education and community service activities, plus the number of lecturerswho forget the password (password) to log in a number of lecturers so that they are neglected in theinput and upload the lecturer tridarma file.

Tablet computer shops as tablet computer sales continue to follow the development of tablet computer technology to meet the needs of tablet computer buyers, where consumers as tablet computer buyers generally always have considerations or factors before making a decision, for example price, brand , the screen size, memory, hard disk, or features available on the tablet computer and other factors. To be able to help with this, it needs to be supported into a computerized decision support system. In addition to providing information, a decision support system can also help provide various alternatives that can be taken in the decision-making process. Fuzzy logic is an appropriate way to map an input space into an output space. Most people think that fuzzy logic is something very complicated and unpleasant, but once someone gets to know it, they will certainly be interested and become a newcomer to learn it

The implementation of the Linear Congruent Method (LCM) in the interactive quiz game based on macromedia selects the suitcase used to generate random numbers. Generating numbers using the linear congruent method uses the formula x(n+1) = (axn+c) mod m. Giving variable values that continue to change greatly affects the game process and can avoid the occurrence of fixed or repeated patterns. In addition, giving a variable that changes can also prevent duplication of questions in a row. Meanwhile, to prevent unwanted random numbers from emitting is to set the variable m as a barrier. From the results of the implementation of the above method in an interactive quiz based on macromedia flash, it can display very varied suitcases that can be played by users with each level of difficulty.

Problems in learning that do not use media in the teaching and learning process and the low ability of children's mathematical understanding in learning flat shape material because there are not many media used for learning. This study aims to obtain the benefits of learning media for flat shapes using Macromedia Flash. This research method uses a research and development model. The development model used is MDLC (Multimedia Development Life Cycle), namely concept, design, material collecting, assembly, testing and distribution. In the field trial, the average pretest score was 68.24 while the posttest average score was 86.76. The average increase is 18.52. The minimum gain value is 0.62 while the maximum gain value is 1.00. In the distribution test the average pretest score is 60.33 while the posttest average score is 81.33. The average increase is 21. The minimum gain value is 0.77 while the maximum gain value is 0.83. Based on these data, the flat shape learning media using macromedia flash software can help improve students' understanding significantly in recognizing flat shapes.
