Abstract

Article presents analysis and analyze a software that utilize Geometry Fractal, especially Iterated FunctionSystem Fractal, as art. Research method that has been used in this research is by library study and by laboratoriumstudy to test the performance of the software. Result of the research has shown that converted music by GeometryFractal has various results, which depend on the parameters used in it and type of Geometry Fractal image produced.It can be said that usage of fractal in high iteration can produce clear image fractal and complicated music fractal.

Abstract

Investment is very popular nowadays to gain profits of the available property. Many investment portfolios are available but there are still a handful of users who have not been able to determine the best type of investment. Surely it would be very unfortunate if the property can not be well invested. Therefore, it is necessary to propose another alternative method that can determine the existing investment portfolio. This method begins by a process which details existing factors in every investment portfolio. Then, it takes intuition properly to give weight to the initial calculation. After that, it takes a Fuzzy concept as a tool to provide a numerical weight to each of the parameters. The final step is weighting process using Dempster Shafer method. With the use of three basic concepts, investors are expected to obtain objective and optimal computing results related to the profitable investment portfolio selection.
