THE EFFECT OF STUDENTS ACTIVENESS IN EXTRACURRICULAR ACTIVITIES TOWARD STUDENT ACHIEVEMENT OF 11th CLASS MAN YOGYAKARTA II ACADEMIC YEAR 2012/2013
This study aimed to determine the effect of students activiness in extracurricular activities toward students achievement MAN Yogyakarta II 11th class academic year 2012/2013.
The population in this study were students of 11th class who take extracurricular activities as much 211 students and the sample was 118 students. The data of student activeness in this study were taken with a questionnaire instrument, while for the learning achievement data retrieved by using the method of documentation, namely student report cards. Validity test of the instrument using Product Moment correlation and reliability test using Cronbach Alpha. Data requirements analysis test using the normality test and linearity test, while for hypothesis testing using simple correlation.
The results of data analysis showed that the students activeness in extracurricular activities are belong to the category of very high (40%), high (30.5%), fair (22.9%), less (4.2%) and low categories ( 1.7%). As for the learning achievement of students belong to the category of very high (7.7%), high (26.2%), fair (33.9%), less (23.7%), and low categories (8, 5%). The results of hypothesis testing showed that there was a positive and significant effect between students activeness in extracurricular activities toward students achievement at a value rcount (0.761)> rtable (0.195). While the significance value (0,00) < significance level (0,05). Regression equation Y = 43.386 +0.498 X showed that the application of students activiness in extracurricular activities increased by one, then the learning achievement increased 0,498. Determinant value R2 = 0.579 which means that contributions effect of students activeness in extracurricular activities toward student achievement were at 57.9%, while 42.1% were determined by other factors
Penyelesaian masalah harga batas persamaan differensial poission dengan metode fungsi green
Penyelesaian masalah harga batas persamaan diferensial Poisson adalah suatu proses untuk mencari solusi masalah harga
batas persamaan diferensial Poisson , atau dengan kata lain suatu proses untuk menentukan fungsi u yang kontinyu pada D dimana u mempunyai turunan parsial kedua yang juga kontinyu pada D sedemikian sehingga memenuhi
Didalam proses mencari solusi tersebut ,terdapat suatu lang
yang sangat penting yaitu menurunkan suatu bentuk fungsi
yang disebut sebagai fungsi Green. dimana untuk menurunkan fung

The Effectiveness of Numbered Heads Together in Teaching Readingviewed From Students' Locus of Control
This writing applied an experimental design. The population of the research was the eighth graders of Senior High School academic year of 2011/2012 consisting of three classes. Two out of the three classes, consisting of 40 students, were used as the sample using the technique of cluster random sampling. The experimental group was taught using the NHT strategy, while the control group using expository strategy. A questionnaire and test of reading were used to collect the research data. The result of analysis shows that NHT is proved as an effective teaching strategy to teach reading for the eighth grade. The effectiveness is affected by students' level of Locus of Control
RANCANG BANGUN BECAK LISTRIK TENAGA HYBRID DENGAN MENGGUNAKAN KONTROL PI-FUZZY
Keberadaan kendaraan becak saat ini mulai berkurang seiring dengan kemajuan teknologi di bidang transportasi. Hal ini sangat disayangkan karena becak merupakan alat transportasi traditional yang nyaman digunakan terutama untuk jarak dekat, selain itu becak merupakan alat transportasi yang ramah lingkungan karena tidak menghasilkan asap kendaraan yang menimbulkan polusi udara.
Untuk tetap menjaga keberadaan becak, penulis akan merancang becak listrik yang bertenaga hybrid sebagai sumber tenaganya. Dengan memanfaatkan solar sell, cahaya matahari diubah menjadi energy listrik. Keluaran energi listrik dari solar sell diinputkan ke rangkaian boost converter,output dari boost converter kemudian digunakan untuk mencharger akumulator untuk mensuplai motor dc. Selain itu dapat menggunakan sumber dari PLN secara langsung untuk mencharger akumulator. Kecepatan putaran motor diatur menggunakan kontrol PI-Fuzzy. Dengan terciptanya becak listrik tenaga hybrid ini diharapkan dapat menjaga keberadaan becak sebagai alat transportasi
