IDENTIFIKASI SPESIES RAYAP PERUSAK TANAMAN JARAK PAGAR (Jatropha curcas L.)
Full text linkCastor bean (J. Curcas L.)can be used for biodiesel material as an alternative to fossil fuels. One of the problems in the cultivation oft his plant is the existence of termite pest. The purpose of this research is to identify termites species that have destructive potencial to castor plants in KIJP Pakuwon. The research was conducted from January to December 2009. As amount of 90 observed stations installed in this area, then divided into three blocks with of each block contained 30 observed station.The distance between each observed station was 20 meters. The termites species that had been collected in every observed station then put in bottles containing 70 percent ethanol and identified its characteristic at Insect Taxonomy Laboratory, Department of Plant Protection, Bogor Agricultural University. Research results showed a numbers of termites species that have potencial destruction to castor plants were Macrotermes sp., Schedorinotermes sp., Microtermes spand Odntotermes sp. Macrotermes sp. was the most dominant species in KIJP Pakuwon

Full text linkModel are a physical medium used to deliver educational content educational materials that can stimulate students to learn. One of the model that can be used in learning, especially learning the human respiratory system are the model of scrap materials. The research was conducted in South Aceh regency Sawang MAN. The purpose of this study was to determine the increase in academic achievement and student responses to the use of model used ingredient in explaining the human respiratory system in Sawang MAN South Aceh regency. The subject of this study was all students in grade XI IPA-1 MAN Sawang South Aceh district, school year 2010/2011. The design of this study is Classroom Action Research (PTK). Instruments used in this study is Teacher Observation Sheet (LOG), Student Observation Sheets (LOS), test (pre-test and post-test), and questionnaire responses of students. Based on the results of data analysis, it is known that an increase in student achievement based on the thoroughness of student learning both individually and classical indication of the success of student learning based on test results (pre-test and post-test), t test analysis, as well as the positive response of students towards learning with use props material scrap materials on the human respiratory system. Teacher and student activities are categorized either as a whole
Peningkatan Ketuntasan Belajar siswa Konsep Lingkungan Menggunakan Multi Model Pada Siswa Kelas X.1 SMA Negeri 4 Bireuen
Full text linkThe Use of Multiple Models in Environmental concepts in SMA Negeri 4 Bireuen. Research purpose is to know the process of learning outcomes through the use of Multi-model on the concept of Environment. The approach used was qualitative descriptive approach types of Class Actions. This study used two cycles with four components, namely planning (planning), action (acting), observation (observing) and reflection (reflecting). Subjects in this study were students in grade lesson X.1 2008/2009 amounted to 36 people. The instrument used was the test at the end of each cycle. To find out the improvement process and the thoroughness of learning, percentage formula is used. The results showed that 44, 44% who have attained completeness in cycle 1. Cycle II obtained by the thoroughness of 88.89%. Students generally respond positively to learning. It is suggested that the use of multiple models can be used on other concepts in the biology of learning to encourage students in learning

Pola Pertumbuhan Kerang Mangrove Geloina erosa Kawasan Ekosistem Mangrove Pesisir Barat Kabupaten Aceh Besar
Full text linkGeloina erosa as one of Bivalve species has growth and development comprising the proliferation of the shell length, volume, and body weight. Generally, the growth of G. erosa has negative allometric, isometric and positive allometric fashion. This encourages the study of G. erosa living in the region of mangrove ecosystem of west-coast of Aceh Besar. The objectives of the research are to determine the growth pattern of shell length against body weight as well as the growth pattern of shell length against its total body weight. The research was conducted from February 2006 to January 2007 in the region of mangrove ecosystem of west-coast of Aceh Besar. The region was divided into three different locations. Each location was set a sample square with 10m x 10m in size which was perpendicular to coastal lines. There were 10 sub-squares also set in every sample square with 50cm x 50cm in size. Sample collection in the sub-square was carried out by scratching and disturbing the bottom of the waters in order to sieve them. G. erosa was then measured for its shell length, body weight, and total body weight. The growth pattern was analyzed by using Excel program and t-test. The result showed that a negative allometric growth pattern was found in the measurement of shell length against total body weight of G. erosa, whereas an isometric pattern was found of the measurement of shell length against its body weight. Moreover, a positive allometric pattern was figured out in the measurement of shell length against total body weight. The proliferation of shell length, body weight and total body weight has contributed approximately 58% to 59%. This indicates that the growth pattern of G. erosa in the region of mangrove ecosystem of west-coast of Aceh Besar has negative allometric, isometric and positive allometric fashion
COMPOSITION AND ANTIMICROBIAL ACTIVITY OF CRUDE EXTRACTS AND ESSENTIAL OIL OF Callistemon viminalis LEAVES
Full text linkAntimicrobial activity of crude extracts and essential oil of Callistemon viminalis against several pathogenic bacteria and one yeast (Candida albicans) were assessed using sensitivity test and MIC determination test. Hexane extract showed the strongest antibacterial activity compared with other crude extracts. While essential oil of C. viminalis in particular showed strong anticandidal activity. GC-MS analysis of crude hexane extract and essential oil have identified the presence of eucalyptol, -pinene, -phellandrene and D-limonene as active antimicrobial compounds in all analyzed samples
