Abstract

Brotowali is a traditional medicine plants have potential as contraception. The active substance from Brotowali is Alkaloid, that have antiproliferative in reproduction cell. This aimed is research to find out the Effects of Brotowali extract (Tinospora crispa L.) in female mice (Mus musculus L., Swiss Webster) fertility. This research is experiment research used completelly randomized design with 4 treatments and 6 replication. The treatments are Brotowali extract, as P1, a dose of 5x10-2 (P2), 6x10-2 (P3) and 7x10-2 (P4) gram/mice. This research was conducted in January 2014 in Zoology Laboratory of Biology FMIPA UNP. The Parameter observed the 0 day of pregnant, length of pregnancy and the number of living pup of mice. The data from the 0 day of pregnant is treated by the continued examination by using LSD at p<0,05. The data of pregnant and the number of pup mice continued by Duncan Multiple Range Test (DNMRT) at p<0,05. The result shows that Brotowali extract (p<0,05) decreased of sum of pup and the day of 0 pregnant. Otherwise, Brotowali extract does not influence the length of pregnant. It can concluded that, Brotowali extract decreased in female mice fertility

Abstract

Items analysis is an activity that can help to increase the learning result test. There are some problems occur, i.e. a difficult item test, the students are difficult to understand the item test, and the item test has not been tested yet. The test result of IPA/Biology for the second semester is classified into low and it is under the Minimum Accomplished Criteria (KKM), i.e. 70. The research aims to give information about the semester test items of VIII class IPA/Biology test of second semester of MTsN Solok city in academic year 2012/2013. The research is a descriptive research, in which the researcher describes and interprets the data as it is. The result of item validity data is for the high criteria i.e. 3 items (6%), moderate criteria i.e. 12 items (24%), low criteria i.e. 18 items (36 %), and very low i.e. 17 items (34%). Based on the good item validity criteria, there are only 15 items (30%) valid. The item reliability is 0.79 included the high criteria, the index of item difficulty for difficult criteria i.e. 25 items (50%), moderate criteria, i.e. 18 items (36%), and easy criteria, i.e. 7 items (14%). The distinguisher items is for worse criteria, i.e. 22 items (44%), moderate criteria i.e. 17 items (34%), good criteria, i.e. 7 items (14%) and bad criteria, i.e. 4 items (8%). The option effectivities are 31 effective key options (62%), 19 uneffective options (38%). The distractor options are 33 effective (66 %) and 17 uneffective (34%).

Based on the results of interview with one of the of biology’s teachers of XI grade at SMAN 1 Solok Selatan, it was found that the students have difficulty to understand the material of reproduction system. It was proved from the results of the students average daily tests that is under KKM (Minimum Achievement Criteri ia) which is 70. Then, teacher at SMAN 1 Solok Selatan had never apply group learning in the form of a team competition and learning is centered on teacher. This research to find out the result of students learning in biology of XI grade at SMAN 1 Solok Selatan in academic year 2013/2014 with the implementation of active learning strategies learning tournament type begins with powerpoint. This research is an experimental study with Randomized Control-Group Postest Only Design. The population of the study are all of XI grade students of SMAN 1 Solok Selatan in academic year 2013/2014 consist of four class. Technique sampling is done by purposive sampling.

Some lacks of module which is used like including words that wrong written including concept written, uninteresting module look, unavailable concept description in detail, and uncolorful picture. The aim of this research is to produce picture module which is completed by map concept in regulation system for class XI in Senior High School. The type of this research is developing the research by using model 4-D developing which is modified from Thiagarajan and Semmel (1974 in Trianto, 2012:94) . In this research including 3 level, they are define, design, and develop. This research has been done and tried in August 28 2014 to two teachers and 30 students in class XII in SMAN 6 Padang. The result of this research is to produce the picture module which is completed with concept map in regulation system material that is valid with the score of validity is 88,54% and valued by construction requirement, and technical . Then the nodule which is produced also include in simple criteria with the value 84,54%, and valued by student interest as variable and module look, process of use, concept and material understanding , time and evaluation. It can be concluded that picture module which is completed with map concept in regulation system material that is produced has fulfilled valid criteria and simple.
