Publisher : Program Studi Pendidikan Biologi

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.

The experiment was conducted at the Laboratory of Biotechnology Faculty of Agriculture, Islamic University of Riau Pekanbaru. In the month of September 2013 - January 2014, with the aim to determine mikropropagasi purple sweet potato (Ipomoea blackie) using BAP and IBA in vitro using Murashige Skoog medium (MS) on the growth of primordial shoots and roots. Parts of the plant which will be used as explants is to take part tuber meristematic tissue concentrations of BAP (0, 1, 1.5, 2, and 3 mg/l) and IBA (0, 0.5, 1, and 2 mg/l). The results showed that there were differences in the growth of explants due to the addition of growth regulators BAP and IBA. Time appears primordial shoots fastest is on treatment (BAP 1.5 + IBA 2 mg/l) with a time of 14 HSK (day after culture) while for the roots of the fastest emerging waktul on treatment (1 BAP + IBA 2 mg/l) with 18 HSK time. BAP and IBA treatment at this concentration has been balanced for growth of purple sweet potato explants. The results of this study will be integrated as a learning resource for high school students of class XII in particular on material in the form of tissue culture techniques Student Task Sheet (LTS).Key Words : Mikropropagasi, Ipomoea blackie, BAP, IBA, sumber belajar

The research of compotition and structure of sapling vegetation at mangrove forest Siakdistrict Riau province had been carriedout on February- Apryl 2014 by survey methodswith plots (10x5) m 2 and transects.The transect was taken place 100 m from coastline. Eachindividual of saplings that account in the plot was measured diameter of breast high. Theparameter were species vegetation, density, frequency, dominancy, importance values,diversity index and similarity index. The results of this research account 11 saplings ofmangrove vegetation at mangrove forest Siak district, they are Avicennia alba, Bruguieragymnorhiza, Excoecaria agallocha, Heritiera littoralis, Hibiscus tiliaceus, Lumnitzeralittorea, Rhizophora apiculata, Rhizophora mucronata, Scyphiphora hydrophillacea,Sonneratia alba and Xylocarpus granatum. Based on index values obtained importantspecies that dominate at each station is Rhizophora apiculata (St.I and III), Xylocarpusgranatum (St.II), and Sonneratia alba (St.IV). Diversity index of sapling vegetation atmangrove forest Siak districtwas moderate. Similarity index analysis of sapling vegetationat mangrove forest Siak district showed that there similarities between the saplingvegetation at I station with III station (IS=54.5%), II station with III station (61.5%), IIstation with IV station (IS=50%) and III station with IV station (76.9%). The results ofthis research was developed into units of learning modules on plant ecology course andthe title is Mangrove Community. Validation results indicate that this unit module is validand can be used by students to learning plant ecology.Keywords: Vegetation, Sapling, Mangrove

A descriptive study on learning atmosphere in the excellence Biology Teacher’s Education Program, The Faculty of Teacher Training and Education, University of Riau has been conducted in the Even Semester of the Academic Year 2012/2013. The objective was to find out the learning atmosphere in English for Biology II courses. As much as eighteen students have been defined as the total respondents by total sampling technique. Data of seven indicators learning atmosphere, namely: (1) cohesiveness, (2) lecture support, (3) involvement, (4) investigation, (5) task orientation, (6) cooperation, and (7) lecture equity obtained by questionnaire What Is Happening In this Class (WIHIC). The questionnaire was valid (rxy0,54>critical values0,3) dan reliabel (r110,96>critical values0,7). The questionnaires were directly distributed to the respondents at the end of the semester. Supplements data were taken by video recording during the learning process. All data were analyzed descriptively. The results showed that learning atmosphere English for Biology II were considered very conducive from aspects of cohesiveness of relationship between students, task orientation, cooperation and lecture equity. While the lecture support, involvement, and student investigations were considered is enough conducive. In conclusion, the learning atmosphere of English for Biology II by using Researchbased teaching were considered was enough conducive. However, the learning atmosphere of English for Biology II is still needs to be improved in order to become very conducive, especially with regard to indicators of lecturer support, student involvement and investigation.Keywdors: excellence biology teacher education programs, english for biology II course, learning atmosphere, research-based teaching
