A surveys of three station along the nesting beach for distribution nesting analysis with beach characteristics and microclimatic nesting green turtles Chelonia mydas in Pulau Jemur-Riau was conducted in April- July 2002. The spatial distribution along the nesting beach namely the nesting abundant at highest the beach slope are 24°-31°, the grain sizes are medium sand (MZ = 2,18) and coarse sand (MZ =1,34). Temporary distribution in the nesting begins in April, extends through May and June, and decreases during July. The coral stones are limiting factor for landing beach success. The characteristic of nesting (beach slope) indicate microclimatic effect on nesting and impacted for distribution was reducing abundant of nesting. Canopy vegetation at highest beach slope are 30° had microclimatic effect on nesting. Key words : Distribution, microclimatic, nesting, green turtles, Pulau Jemur

PENINGKATAN AKTIVITAS DAN HASIL BELAJAR BIOLOGI MELALUI PENERAPAN MODEL PEMBELAJARAN KOOPERATIF DENGAN STRATEGI GIVING QUESTION AND GETTING ANSWSER PADA SISWA KELAS X2 SMA NEGERI 1 BENAI TAHUN AJARAN 2011/2012 Arnentis '; Wan Syafi’i; Desti Nurfa Dila

This study aims to increase the activity and student learning outcomes through the implementation of cooperative learning model by giving answer to the question and getting the class X2 Benai SMA N 1 academic year 2011/2012. This research is a class action, which was conducted in January-February 2012. Subjects were high school students X2 N 1 Benai class numbering 36 people, consisting of 16 men and 20 women. Parameter studies are student activities and learning outcomes which consists of studying the absorption and completeness. Average student activity on the cycle I is 74.87% (enough) and increased in the second cycle is 81.28% (good). Average absorption of students in the cycle I is 78.94 (enough) and the second cycle which had an average of 80.42 (good). Thoroughness of student learning in the cycle I was 91.67% (excellent) and 97.22% (excellent) on the second cycle. I cycle a group award in any super group 4 and 3 great group and the second cycle of all groups received a great award. From the research results can be concluded that the use of cooperative learning models by giving a strategy question and getting answer can increase the activity and students' high school class X2 N 1 Benai in the academic year 2011/2012.Keywords: Activities, Cooperative learning, Learning outcomes, The strategy giving question and getting answer.

Classroom Action Research has been conducted (PTK), which aims to improve the scientific attitude and learning outcomes with the implementation of IPA Biology cooperative learning model types Course Review Horay (CRH) in VIII.1 grade students at SMP Negeri 2 Pekanbaru. The study was conducted from October to November 2011. The study subjects were 36 students (17 male and 19 female). Parameter is the attitude of scientific research, the study (absorption and completeness of student learning), award groups, student activity and teacher activity (as the supporting data). Data were analyzed descriptively. The results indicate that the cycle I mean the scientific attitude of students is 82.25% (enough), the average absorption of students is 81.08 (enough), the thoroughness of student learning is 80.56% (enough) and group awards a super predicate there are 4 groups. In the second cycle the average scientific attitude of students increased to 90.99% (good), the average absorption of students is 89.61 (good), exhaustiveness of student learning is 100% (excellent) and a group award super predicate there are 2 groups. From the research results can be concluded that with the implementation of cooperative learning model of the type of course review horay (CRH) may increase the scientific attitude and learning outcomes VIII.1 grade Biology students of SMP Negeri 2 Pekanbaru Lessons Year 2011/2012Key words : Models of Cooperative Learning Type Course Review Horay (CRH), Scientific Attitudes, The Study of Biology

A research was conducted to find out the effect of papaya latex (Carica papaya L) toward the mortality of Aedes albopictus larva, in Laboratory of Biology Faculty of Education Teacher Training and Education University of Riau in November 2011 to April 2012. The method used in this research was experimental method to the preparation of a random sample consisting of 5 treatments which are repeated for 3 times. The number of larva are 10. Parameter observed is Aedes albopictus larva mortality as long as 96 hours, LC50 value and toxic response of Aedes albopictus larva which could be showed by body movement, posture and body color of larva. The data of this research was analyzed by probit and deskriptif analysis. The supporting parameters is temperature and pH of the medium. The results of the research showed that the papaya latex (Carica papaya L) could make the mortality of Aedes albopictus larva. Mortality of Aedes albopictus larva in concentration 27 ppm was 100% in 24 hours, in concentration 18 ppm was 100% in 72 hours, mortality of Aedes albopictus larva in concentration 12 ppm and 8 ppm was 80% and 50% in 96 hours. LC50 value in 24 hours was 26.30 ppm, in 48 hours was 20.41 ppm, in 72 hours was 14.12 ppm and 96 hours was 9.12 ppm. The roxic response of Aedes albopictus larva showed the mobility of the less agile, larva body roll, the larva's body parallel to the surface of the water and the color of pale white body. From the result of the research can be concluded that the papaya latex can potentially lead to death of Aedes albopictus larva and the concentration recommended for application to the environment is 9.12 ppm in 96 hours.Keywords: Aedes albopictus larva, Papaya late.
