Abstract

Have done the classroom action research was to know the increase of result  learn biology with to approach of STAD Cooperative learning to student class II SMUN  1 Selat Panjang on February – April 2004.  Samples were collected students class II.1  to amount 42 people.  Various parameters such as: Student reserve capacity, produce student learn, student development value, teams appreciation value and students activity. The result of student learn at Cycle I with concept Food and Digestion System at meeting I (81,62), meeting II (79,02), meeting III  (74,22) and meeting IV (82.43). At Cycle II with concept Excretory System of average value at meeting I (83,59), meeting II  (84,86) and meeting 111 (87,29). For student development that contribute for teams appreciation value at Cycle I, 8 teams to get super appreciations and  1 team to get enormous appreciation. Whereas at Cycle II, from 9 teams, all teams to get super appreciations. The Student activity in cycle I equal to 77.19 (very well category), cycle II  equal  to 84.85  (in  very  well  category).  Based  on  the research result,  that  approach of STAD Cooperative Learning can to increase the result of student learning.   Key words : Biology, Cooperative learning

Abstract

  Have been conducted by a research to know the accumulation of metal Zincum (Zn) and Cupprum (Cu) in territorial water of  Siak River by using thyroid bioaccumulator Water hyasin (Eichhornia crassipes) what is conducted at month April-Juni  2004.  Method  used by that is survey with the technique of intake sampel  by purposive random sampling at 5 station.  Research parameter is content of metal Cu, Zn in thyroid and Water hyasin, temperature, brightness, dissolved oxygen, pH, nitrate and pospat. Analyze the data conducted descript result. The Result of research show concentration in territorial water Siak River metal Cu at height level at range 0.14-0,27 mg/1 and metal Zn low level at < 0.001 mg/1. Accumulation of metal Cu and Zn in Eichhornia crassipes height level categories, while at root 14,5-24,0 mg/1, at bar 8.0-16,0 mg/1 and at leaf 25 0-39,5 mg/1. Accumulation of metal Zn at root 74,0-189,5 mg/1, at bar 23,5-165,5 mg/l and at leaf 11,0- 9,0 mg/l.   Key words :  Metal Cu , Metal Zn, Bioaccumulator Eceng gondok (Eichhornia crassipes)

Abstract

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.     Key words:  Seed of orchid, Gibberellins,  In vitro, Germination, Phalaenopsis amabilis Bl

Abstract

The research was to examine effect restricted feeding in lenghorn chicken, in Labuh Baru Pekanbaru from June -August 2001.  The experiment was conducted  using completely Randomized Design ( R A L )  with three replications. The treatment consist of A (Full  feeding without the fast), B (Three days full feeding, one day the fast), C (six days full feeding, one day the fast). The treatment each consist of five  lenghorn chickens Various parameter such as food consume, increase body weight and food conversion. Data were analyzed using Anava with  DMRT  5 %  level of signification. The result o f this experiment showed that effect  restricted  feeding significance to  food  consume,  increase  body  weight  and  food  conversion  in lenghorn chicken.  The treatment C, was good to increase body weight and food conversion, where as the treatment B to food consume.   Key words : Consume, Conversion, lenghorn chicken, restricted feeding
