Abstract

The aim of this experimental study is to know the effect of cottonseed extracts toward the reproduction of mice (Mus musculus L., Swiss Webster). This experiment used completely randomized design with 4 treatment and 6 replied. Treatment given was cottonseed extract with several dose, namely control (0 gram/mice), 0,03 gram/mice, 0,05 gram/mice and 0,07 gram/mice. This research was conducted on Desember 2013-January 2014 in animal house Zoology Laboratory Majors Biology FMIPA UNP. The parameters are vaginal smear, corpus luteum number, implantation, life fetus, died fetus, abnormal fetus, resorpsion fetus and average of weight fetus. Data is analyzed by ANOVA and DNMRT significant p (0,05). The result shows that cottonseed extract indicated that there are extension proestrous, metestrous, and diestrous. It can conclude that cottonseed extract influenced mice cycle reproduction. The cottonseed extracts indicated there are decreasing corpus luteum number, implantation number, life fetus number and average of fetus weight were compared by control. This research concludes that cottonseed extract (Gossypium hirsutum L.) influenced the performance reproduction of mice (Mus musculus L., Swiss Webster). Key words: gossypol, fetus, cycle and performance reproduction

Abstract

This study aims to determine the effect of the number of doors eating quail egg production. The study population quail - coturnic Coturnix japonica strains 500 hatching tails of the results using the incubator. All members of the population have the same criteria include age, weight, health , and gender. The design used in this study is completely randomized design with 5 treatments and 5 replications. Treatment (A) 20 tail with 20 % quail feed doors, treatment (B) 20 tail quail with 40 % door dining, treatment (C) 20 tail quail with 60 % door dining , treatment (D) 20 tail quail with 80% of doors eating, treatment ( E ) 20 tail quail with 100 % door to eat. Further test used is Advanced Test Significant Difference at 5% level. The results showed that the number of doors eating very influential on the production of quail egg. Egg production was highest on the cage doors have eaten as much as the number of quail. Lowest egg production contained in the enclosure that has a door to eat as much as 20 % of the number of quail with the effect of each treatment is very real.Key words: total door eat , quail egg production

Abstract

Learning achievement on Biology subject of the eleventh grade students of SMAN I Koto XI Tarusan was still low due to teachers’ dominance in learning process, and students’ lack of interest toward instructional media used by their teachers. The use colorful puzzled picture for instructional media was expected to be able to stimulate learning activity and arouse students’ motivation and, in turns, improve students’ learning achievement. This research was therefore aimed at figuring out the effect of using colorful puzzle for instructional media in cooperative learning, especially  Number Head Together type, upon Learning achievement on Biology subject of the eleventh grade students of SMAN I Koto XI Tarusan in the academic year of 2010/2011 academic year. This research employed quasi experimental with Static Group Comparison which compares the use colorful puzzled pictures for instructional media and colorful pictures only. The population was all eleventh grade students of SMAN I Koto XI Tarusan in the academic year of 2010/2011 academic year. Sampling technique was purposive where XI IPA5 and XI IPA6  were chosen. Data from final test was in the form of objective test consisting 40 items were analyzed to test the hypothesis using t-test where if  t calculated > t table, then the hypothesis was accepted.Kata kunci: puzzle, gambar berwarna,  NHT, hasil belajar, biologi
