Abstract

The convertion of wind energy into electrical energy in laboratory is experimentally conducted, to the source of the wind came from the fan, which then flowed into a tunnel. The generator used is bicycle dynamo with voltage output of 12 Volt. The wind speed against the tunnel lenght increases when the length are 0,90 m, 0,75 m, and 0,60 m, and decrease on 0,45 m and 0,30 m. The decrease of wind speed occur because of fan vibration, unregularity of tunnel surface area and turbulence. The wind speed is observed to be the largest on the length of 0,60 m with the wind speed at the level of the third button of fan its average speed of 4,16 m/s with generator power, torque and efficiency are 9,47× 10−3 Watt, 2,63× 10−1 Nm and 0,30% respectively. The current and voltage output produced by generator is AC current and voltage and resulte 72,85 mA dan 0,13 Volt, therefore to convert they into DC current and voltage output, effective current and voltage equation is applied which get 0,05 Ampere and 0,09 Volt.

Abstract

This article discusses the family of Laguerre method to find multiple roots of non-linear equations with a known multiplicity. Analytically, we show that this iterative method has a convergence of order three. Furthermore, by choosing the value of certain parameter in the Laguerre method, we obtained several well-known iterativemethods. Using some test functions, we compare the family of Laguerre methods to obtain a root of nonlinear equation by looking at the number iterations of the methods. In addition, comparisons are also made through Basins of Attraction.

Abstract: This study is a class act. The study is based on classroom learning conditions of class VIII3 SMP 25 Pekanbaru are still problematic, where the value of learners is below the KKM and learning are still centered on the teacher. Therefore, this study aims to improve learning process and improve mathematics learning outcomes. The subject of this research is VIII3 grade students of SMP 25 Pekanbaru on odd semester 2014/2015 in academic year, which amounts to 40 people consisting of 13 men and 27 women with heterogeneous levels of ability. This study consisted of two cycles, each cycle consisting of four phases, namely planning, action, observation and reflection. Each end of the cycle performed quiz. Data collected through observation and tests in the form of a quiz. Data analysis technique in this research is the analysis of qualitative data and quantitative data analysis. The results of research on the observation sheet showed the activity of teachers and learners increasingly performing well after doing the action. Based on the observations of researchers during the learning process in the classroom VIII3 SMP 25 Pekanbaru, most of the students were active in the learning process are implemented. Achievement attitude in its development more visible in working LKPD, as evidenced by an increase in the number of learners who achieve good and very good category. Same with the attainment of skills of students, number of learners who are skilled and skilled enough to rise. The percentage of students who achieve the KKM knowledge base score, quiz I (first cycle), replicates quiz II (second cycle) respectively is 42.5%, 65%, and 67.5%. Action is successful if the state after the action better.
