Abstract

The purpose of this research is to describe the profile of creativity in solving geometry problems of junior high school students based on cognitive styles of reflective. The assessment of creativity is based on the assessment in solving geometry problems which made by the subject that consists of the three aspects of creativity, which are: fluently, flexibility, and novelty. The aspect of fluently in solving geometry problems is considering on the ability of students for making many of correct solutions. The aspect of flexibility in solving geometry problems is considering on the way of making different correct solutions. The aspect of novelty is considering on the ability of students on making different solutions from previous answer which noted as usual. Two solutions are different if the concepts or context which made by the students are different or unsual compare to the ability of others in their ages. This research is descriptive research by using qualitative approach. The research is taking place on class VIIIA SMP YDWP (Yayasan Darma Wanita Persatuan) UNESA in May on school year of 2010/2011.

Abstract

Rabies is a fatal zoonotic viral disease caused by a virus which attacks the central nervous tissue. According to the World Health Organization (WHO), every year as many as 55,000 people die because they were infected by rabies virus. It is estimated as many as 95% of the incident occurs in Africa and Asia. Almost 99% of the transmission of rabies virus to humans is caused by dogs. It required some efforts to halt the spread of rabies. Some of which is by vaccination and culling the dogs. A mathematical model is required to analyze those efforts so that they became optimal when they applied to the field. Dogs population can be divided become two compartment as healthy (X) and infected dogs ( ). The model will be analyzed using linearization method to determine the characteristics of the population dynamics of healthy and infected dogs. To strengthen the analytical results, will be simulated using Runga-Kutta 4th order method. The result of the research showed that vaccination and culling methods are less effective in eradicating rabies, but by doing a certain level of vaccination and culling level of dogs, the eradicating of rabies spreading still can be done as long as it meets certain criteria.

Abstract

In mathematics, beauty can be thought of as a "certain expectation" for a "natural outcome". Mathematical sciences application have appeared in the field of art, particularly music. One example of its application namely Fibonacci sequence and Golden Ratio. This research aims to create two songs with the Fibonacci sequence and Golden Ratio. The first song were created by applying the elements of the Fibonacci 100% while the second song with the implementation of Fibonacci 64%. Then the sense value ratio from both songs are analyzed using the Wilcoxon test with 16 respondents from ISI Denpasar students (Indonesian Art Institute in Denpasar). This research is expected to add knowledge about the mathematics application to the arts, escpecially the art of music.
