ABSTRACT This study was conducted to determine the rate of leaf litter decomposition in Forest Areas native Prohibition Rumbio in September 2014 and January 2015. The study was conducted with phase field research. Determination of the research station in purposive sample by three research stations as representing the forest community as a whole. At each station gets 15 bags of waste and the waste that is deposited on the forest floor litter bags were collected every interval of 15 days and dried for 75 days in the oven for 48 hours at a temperature of 70oC – 75oC. Each station measured soil temperature, soil moisture and pH of the soil and the types of trees on a plot measuring 20x20 m. The results showed the rate of leaf litter decomposition in Forest Areas native Prohibition Rumbio for 75 different days in each station, station 1 at a rate of waste decomposition leaf 0.0028 gr/m2/day, station 2 with a blade speed of waste degradation of 0.002 gr/m2/day, and the station 3 with the leaf litter degradation rate of 0.0018 gr/m 2/day .

ABSTRACT The aims of this research to determine the effect of the hormone 2,4-D and BAP on callus growth Kasturi Orange (Citrus microcarpa). This research consisted of research using experimental method completely randomized design factorial. Parameters observed is percentage of explants, while appearing callus, callus width and texture of the callus. Research results and a growing percentage of the width callus explants were analyzed by ANOVA and a further test DMRT at 5% level, when it appears callus and callus texture done by descriptively. The result shows that a combination of hormones D4B1 and D4B2 produces a callus emerged fastest of 3.3 HSK. The highest percentage of callus formation that is 100% contained in the treatment of D2B0, D2B0.5 - D4B0. The mean width of callus was highest in treatment D4B2 with a width of 0.97cm. Embryogenic callus resulting by treatment of D2B1, D2B2 ,and D3B0. Keywords: Hormones, Callus, Orange Kasturi

ABSTRACT This research aimed to determine the effect of Kinetin and NAA on the growth of explants Musk lime (Citrus microcarpa) and to design learning resource for student work sheet based virtual laboratory. This research was conducted at the Laboratory of Biology Education University of Riau and Laboratory Biotechnology of Riau Islamic University from April-Mei 2015, using a completely randomized design of 4 x 4 factorial with three replications. The first factor (K) is the Kinetin consists of 4 level: 0 ppm, 1 ppm, 3 ppm, and 5 ppm. The second factor (A) is the NAA consist of 4 level: 0 ppm, 0,5 ppm, 1 ppm, and 2 ppm. Parameters measured were percentage grows, time of root rise, time of bud rise, the amount of buds, amount of roots, and lengt shoot. The data were analyzed using ANAVA and tested further by DMRT at 5% level. The data were analyzed using verification by lecturer for development student work sheet . The results of this research showed of Kinetin and NAA significantly affect the growth of explants Musk Lime. The percentage of explants grown 100% all treatments, except treatment K5A0, The earliest of root rise in treatment K0A0,5 HST, The earliest of bud rise in treatment K5A0 HST, Highest amount of buds in treatment K3A2 is 2.4 buds, Highest lengt of shoot in treatment K3A0 is 7.1 buds, and the amount of roots the best treatment of K0A0,5 is 8,1 roots.

ABSTRACT The aim of this study is the development learning module biology ipa scientific oriented approach for improved critical thinking on the structure of plants in class VIII SMP. The research was conducted at the campus of the University of Riau FKIP Biology Education and Student responses conducted in SMP Negeri 1 Pekanbaru in March to December 2015. This study uses 4-D model of development. Stages 4-D consists of four stages, namely Define (Definition Phase), Design (Stage Design), Develop (Development Phase), and Disseminate (Phase dissemination of). Data collection instruments used were sheets of validation and student questionnaire responses. Sheets validation judged by five validator which is composed of three lecturers and two junior high school teacher that consists of four aspects: the feasibility of the content, language, and kegrafisan dish. Results of the study the average score for the validation of the feasibility aspects of the content, language, serving and graphic on module to obtain an average score of 3.4 with very valid category. Feasibility aspects contents obtained an average score of 3.5 in the category of very valid, linguistic aspects obtained a score of 3.4 with very valid category, next to the aspect grain obtained a score of 3.4 category is very valid, and aspects kegrafisan obtain an average score of 3, 3 categories are very valid. While the average score of students' responses to a questionnaire developed module is 3.4 to excellent category.

ABSTRACT The purpose of this study was to develop a learning module oriented guided inquiry model of the material circulation system of class XI in improving students' critical thinking skills. Research conducted at the Laboratory of Biology Education Studies Program Faculty of Teaching and Education University of Riau and SMAN 1 Pekanbaru in February 2015 - May 2016. The research is a research development by using ADDIE model of integration to the stage of development. Instruments of data collection in this study is the assessment sheet / validation module, student questionnaire responses and critical thinking skills assessment sheet. Once the module is developed, validated by 4 validator then the tests I at 12 4th semester students of biology education FKIP UR and II trials in 20 students in Class XI SMAN 1 Pekanbaru. The tests for aspects of the content presented, language, presentation and kegrafisan module obtained an average score 4.20 (valid). Aspects of the content presented is obtained an average score 4.28 (very valid), aspects of language obtained a score 4.07 (valid), then to obtain a grain aspect score 4.16 (valid) and aspects of kegrafisan obtain an average score 4.30 (very valid). In the student questionnaire responses in the experiment I belong to the category module SB (Very Good), while the second test the response of 20 students of the modules developed is 84% in one study and 82% in the second study with either category. As for the average results of analysis of students' answers on the learning modules acquire 82% considered good value. Based on the results of data analysis can be seen that the module-oriented model of guided inquiry learning to enhance students' critical thinking skills in class XI material circulation system that has been developed can already be used with a valid category.
