Abstract

Study of the set properties is simple and rarely investigated at the Department of Mathematics. This paper examines some set properties on the irrational numbers. The study is about the properties applying to the real numbers which are a complete ordered field. However, the results of this study show that those properties do not imply to the irrational numbers, but the ordered property. The prove of the irrational numberby some examples is demonstrated in this study.

Abstract

One indicator of the success of a government is the decreasing in the poverty rate. This paper aims to predict the percentage of poverty in the province of Aceh based on 9 years time series data, from 2005 up to 2013. The research method is autoregressive model . The data is secondary data obtained from Badan Pusat Statistik (BPS – Statistics Indonesia) of Aceh Province. The model obtained is . Based on the model  The prediction of the level of poverty in Aceh for 2014 is 18.27 percent of the total population of Aceh. This prediction has an error value of 0.22 and 1.29 respectively to the percentage of the poverty level in Aceh in March and September 2014. When viewed by urban and rural, the model  obtained is  and respectively for urban and rural. While the predictive value of the poverty level in Aceh in 2014 for urban areas is 11.73 percent and in rural areas is 20.81 percent.

Abstract

Adobe Flash is a software that is used to build an interactive contents that can be attached in other things, such as presentations, games and e-learning. The Eulerian Circuit Search Instructional Media is one of examples in using Adobe Flash in building an interactive instructional media to solve graph theory problems. Visually, Adobe Flash is better than other programming software in general and it is the most suitable one for graph theory, as it uses graphics and visuals to solve problems. The weakness of Adobe Flash is when doing large scale calculations; such as when testing algorithms to find Eulerian circuits. Then an idea came about to complete the large scale calculations in Adobe Flash, which is commonly known as script time limit, with using other methodologies by changing script time limit on the settings, algorithms, partition the processes, and utulize the timers within the objects in the actionscript that handles the search algorithms of searching Eulerian circuit.
