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

This study aims to determine the growth of tilapia (Oreochromis niloticus) with the use of Azolla microphylla feed and its potential to produce a module design on the material for growth and development of living things in class XII odd semester KD 3.10 and KD 4.10.This research was conducted from May to August 2020 at Danau Selais LPPM Riau University. This study used 2 stages, namely. Phase I research used quantitative descriptive to determine the growth of tilapia on Azolla microphyla feed with different feeding percentages. Fish were grouped into 3 treatments and 1 control. Fish are reared in different cages with different percentage of feeding. The research parameters included absolute length growth, absolute weight growth, nisbi growth rate, and survival rate.Phase II research is a module teaching material design that uses 2 stages, namely, the Analyze and Design stages.The results of the experimental stage of research, feeding Azolla microphylla affected the growth of tilapia (Oreochromis niloticus). P3 treatment (giving 5% Azolla microphylla from fish biomass) is the best dose in increasing the growth of tilapia. Resulted in the absolute length growth of 4.24 cm, absolute weight 11.72 g, 4.68% relative growth, 4,68% specific growth rate and 99.4% survival rate. The P3 treatment resulted in a growth which was much lower than the P0 treatment (control).

In vitro investigation has conducted in order to find out the respons of orchid (Phalaenopsis amabilis BI) in Vacin and Went media by Gibberellins treatment, this research was carry out at Balai Benih Tanaman Pangan dan Holtikultura Pekanbaru during June until August 2003 by using completely Random Design through 5 treatment and 4 replication. The treatment were Gibberellins (ppm): 0, 2, 4, 6 and 8. The parameter were observed i.e ; the emergence timing of protocorm like bodies, seedling height, and seedling biomass. Observated data were analyzed descriptifely and analysis of variance with Duncan Multiple Range Test at 5% level of significance. The results shows that the 2 ppm GA3 treatment have a good effect on the emergence timing of protocorm like bodies (13-16 days after planting), average of seedling height (1,5 cm) and seedling biomass (1,18 gr). We concluded that the timing of orchid seedling emergence could be accelerated by increasing the concentration GA3 treatment until 2 ppm.

ABSTRACT So far, the teacher's learning is mostly presented with lecture method and only centered on the teacher, it causes the critical thinking of the students is still very rare in the learning process, besides critical thinking other thing to note is student's cognitive style.Therefore it is necessary to do research about the empowerment of critical thinking in terms of reflective and impulsive cognitive style. The purpose of this study is to describe the ability of critical thinking students reflective and impulsive cognitive style through SQ3R learning model (survey, question, read, review, recite) by using Audio Visual media. The subjects of the study were students of class VII-B MTs. Muhammadiyah 3 Sedayulawas amounted to 20 students consisting of 10 students of reflective cognitive style and 10 students of cognitive impulsive style. Technique of collecting data by using test, for data koSo far, the teacher's learning is mostly presented with lecture method and only centered on the teacher, it causes the critical thinking thinking of the students is still very rare in the learning process, besides critical thinking other Thing to note is student's cognitive style. Statistically non-parametric by using Mann-Whitney Test.The results of this study indicate that there are differences in reflective and impulsive students' critical ways of thinking ie impulsive students show higher results from reflective students. Thus it can be concluded that the critical thinking ability of cognitive-impulsive students is higher than in reflective cognitive students in Biology learning through SQ3R model (survey, question, read, review, recite) with Audio Visual media.

This research was conducted at the Natural Laboratory of Education and Teacher Training University of Riau in April to June 2013. This study used a completely randomized design with 9 treatments and 3 replications. The material used is the earthworm (Lumbricus rubellus) as much as 270 worm with averaged biomass and body length. Organic materials as artificial feed (P1) tofu, (P2) kakawatan grass, (P3) chicken manure, (P4) cow manure, (P5) tofu + chicken manure, (P6) + kakawatan grass + tofu, (P7) chicken manure and kakawatangrass (P8) + cow manure + tofu. Parameters measured were the length and biomass of earthworm for 60 days after planting (at the beginning and end of the research). Proponent parameters measured were pH of soil, temperature of soil and moisture. Data were analyzed using analysis of variance (ANOVA) followed by DMRT (Duncan Multiple Range Test) at the level of 5 %. The results showed increase length and biomass of earthworm (Lumbricus rubellus) is highest at (P4)treatment (cow manure) which is 0.214 g/tail, long worms present in the (P2) treatment (kakawatan grass) which is 4.99 cm and the lowest on all parameters is the (P0) treatment (no treatment). The results of the research can be used to support the learning process in the form of Student Worksheet (LKS).Keywords : Lumbricus rubellus, Growth, Artificial Feeding, LKS
