Abstract

Marquisa is one of favourite fruit in Indonesia. However this plant is oftenattacked by diseases, one of them is Bactrocera dorsalis. There is no information yetabout what interest Bactrocera dorsalis to marquisa does. Based on the problem, theaim of the research is effect of marquisa extrac t (Passiflora edulis varietas flavicarpa)toward Feeding Strategy of fruit fly Bactrocera dorsalis Hend. T his research wasexperimental research used cilinder Y tube method, with match treatment and includes10 repetitions. The research was conducted from October 2012 to February 2013. Theresult, show that marquisa extract have effect toward Feeding Strategy from fruit flyBactrocera dorsalis. On the searching activity, the fastest time of fruit fly reachedmarquisa was at the treatment V (75,13 seconds) although longest time was at treatmentI (256,33 seconds). On the grounding ac tivity, the fastest time of fruit fly reachedmarquisa was at the treatment V (45,23 seconds) although the longest time of treatmentI (58,7 seconds). Based on Chi-square analysis the treatment had the higher differencebetween petrogenol and marquisa extract, excepting treatment 3 ml of marquisa extractand 3 drops of petrogenol did not have real difference between petrogenol and marquisaextrac t. It cand conclude that marquisa extract had effect toward Feeding Strategy offruit fly Bactrocera dorsa lis.

Abstract

ABSTRACT             Penicillin G acylase is an enzime that catalyzes the hidrolysis of penicillin G acylase into 6-aminopenisilanat acid (6-APA). 6-APA is a basic ingredient inthe manufacture of semisynthetic penicillin. Acylase penicillin G can be by produced of microorganisms, such as fungi penisillium and various types of bacteria, such as Bacillus, Escherichia coli. Acylase penicillin G producing bakteria have been isolated from saveral rivers in the Padang city, but the identification has not been done. Associated with it to identify bacteria producing penicillin G acylase of saveral rivers in the Padang city. This research aims to determine the type of bacteria producing penicillin G acylase of saveral rivers in the Padang city. This research was conducted in July 2013 laboratory Kopertis Region X and in August 2013 in the Balai Penyidikan and Pengujian Veteriner Regional II Bukit Tinggi. Identification is carried out morphological and biochemical. The research uses desckriptive method. Results of bacterial identification by morphological and biochemical which shown that the bacteria producing penicillin G acylase of saveral rivers in the Padang city is a bacterium of the genus Bacillus.

Abstract

Epilitic algae is part of a group microperifitic algae that lives attached to the substrate (stone,coral, gravel and other hard objects). Solok Regency has Talang Mount with the beautifulnatural that can be enjoyed, this place also has a hot water source in Bukik Gadang, NagariKoto Anau, Lembang Jaya District, Solok Regency which is believed has a power to heal ortreat and as a tourism object. The temperature of hot water is about 39 – 45 ºC. The researchof epilitic algae in Bukik Gadang hot spring, Lembang Jaya District, Solok Regency in haddone Desember 2012 – Maret 2013. The purpose of this research to know the variety ofepilitic algae at different temperatures. This research has done by using a descriptive surveymethod with determining three station based on the different temperatures and sampling wasdone by purposive sampling at each station were taken three points. This research found 17species of epilitic algae consist of two classes of Bacillariophyceae and Cyanophyceae. Theclass Bacillariophyceae found 9 species and class Cyanophyceae 8 species that live attemperatures of 39 – 45 ºC, pH 7,01 – 7,50, dissolved oxygen 1,44 – 3,96 mg/l, the sulfurcontent from 0,089 – 0,105 mg/l.

ABSTRACTPractical requires students to be able to work in the lab or in the field. By carrying out their practical acquire knowledge, understanding, and behavioral aspects of the other, and to develop the skills to live in society meaningfull. In addition, the students will find themselves contribute to arouse their interest and enthusiasm for learning. Implementation of practical activities in schools need practical guidance so that students more easily understand the material that will be practicalled. However, at school SMAN 1 Lembah Melimtang students conducting lab does not have specific guidelines or guiding practical. Accordingly, the research aimed to result a valid and practical guidance practical. This study is using a three-stage development of the 4-D models, the stage define, stage design , and development stage (develope). Test subjects were students of class XI Science SMAN  1 Lembah Melintang, amounting to 30 people. The data of this study is primary data taken from  validity and practicalities are then analyzed with descriptive analysis. Practicalities by teachers who are included in a very practical and practicalities criteria by 87.85% students with practical category. It can be conclude has produced valid and practic a guide with pictures on a cells material for class XI SMA.

Abstract

ABSTRACT Muaro is one of the water bodies in which a variety of living organisms, the organism is clam shells Polymesoda bengalensis is known by the public as the seashell. The shells used by people around for a living because of the economic and nutritional value is very high. Current where abouts shellfish habitat Polymesoda bengalensis already disturbed. The most serious threat to the population is the result of harvesting clams and mussels taking excessive. Organisms that live in Muaro depending on substrate conditions and salinity, the salinity fluctuations depending on topography estuaries and tidal influence, the substrate  showed  differences  with  population densities. This factor  caused by  each type of  substrate occupied by Polymesoda bengalensis shells with different age groups. This study aimed to determine the distribution of oyster shell length and physical factors-water chemistry of mangrove clams Polymesoda bengalensis in Muaro Nipah Kecamatan Sutera Kabupaten Pesisir Selatan. The research was conducted in  January  2013  in  Muaro  Nipah  Kecamatan  Sutera  Kabupaten  Pesisir  Selatan.  Analyzes  were Polymesoda bengalensis conducted in the laboratory Animal Ecology Department of Biology, Faculty of Mathematics  and  Natural  Sciences,  Andalas  University  in  Padang,  this  determination  using  survey methods and sampling techniques using purposive systematic stratified random sampling in three locations determined by vegetation. Results of sample analysis shells Polymesoda bengalensis obtained size comparison long: thick : high = 2 : 1 : 2, there is a close relationship between the length and height with thick shells Polymesoda bengalensis. Biomass of meat is determined by the length, thickness and height shells. Length ranged shells 2.9–7 cm. Shell size distribution in strata I and III predominantly young individuals, in strata II adult individuals while on location I and III predominantly young individuals and locations II dominated by adult individuals.

Abstract

ABSTRAK Ferns are heterogens in terms of his place, there are the kinds of spikes that live on land (terrestrial), there is a ride of his life on other plants (epiphytes), and there are spikes that grow in water (higrofit). Bukit Barisan is a limestone hill forests has the conditions and rock properties that are different from other forest types. The study was conducted by survey method by direct observation and collection. From the research that has been conducted in the Bukit Barisan Forest Jorong Halalang Nagari Kamang Mudiak District Kamang Magek terrestrial obtained 12 types of nails.
