Abstract

ABSTRACT Corbicula sumatrana Clessin is typical of freshwater mussels or brackish water economically valuable. C. sumatrana Clessin a shellfish known people with the name pensi. Pensi consumed by people as a source of animal protein and animal feed ingredients. Singkarak Lake used by people in daily life from the source of drinking water, toilets, fisheries, irrigation, PLTA and Tourism. The many activities of the community could be expected to cause pollution and affect the C. sumatrana Clessin. Shellfish become vectors of biotoksin because his diet filter-feeder. Pensi meat is an excellent medium for bacterial growth. This study aims to determine the presence of Escherichia coli and Salmonella sp. on fresh meat Pensi (C. sumatrana Clessin) originating from Singkarak Lake. The research was conducted in July - August 2013. This research is a descriptive method, by looking at and analyzing the presence of microorganisms are bacteria E. coli and Salmonella sp. The method used to determine the bacteriological quality of the meat is pensi by MPN method and examination of Salmonella. Data were analyzed by calculating the number of bacteria E. coli by observing the number of positive results of the estimation of presumptive test, confirmative test and completed test. The next number of bacteria from each positive results are matched with MPN table. Test Salmonella sp. done by looking at the colony grows. Results of bacteriological tests on meat samples were examined in Microbiology Laboratory Research and Industry Standards (BARISTAND Industry) Padang showed that of the four samples tested, three of which were positive for the bacteria E. coli samples take in Nagari Tikalak, Nagari Singkarak, Nagari Saning Bakar and all samples contained Salmonella sp. Of this study is suggested to consumers that cooking pensi perfectly, to avoid diseases that may occur because it is caused by bacteria.

Abstract

ABSTRACT Dragonflies (Odonata) is a species insect that have numbered middle until large and attractive colour. Type of dragonflies Orthetrum sabina have much and found in Java island, and they as predator insect. The goals of this research is would like to know the  population of Orthetrum sabina (Odonata; Libellulidae) in Kanagarian air Bangis, Sungai Beremas district, Pasaman Barat Regency. The research was conducted in Februari 2014. This research is survey descriptive research. Sample of research done for 1 week with condition rice field that flooded and dry land are 3 days in the light months and 3 days in dark month. From the result of population Orthetrum  sabina  in  Kanagarian Air  Bangis  found  that  characteristics  of  Orthetrum  sabina average abdomen length 29-30 mm and body length 50-53 mm have compound eyes green colour with slender abdoment. Totally population of Orthetrum sabina in wet rice field (0,99 indvidu/ m2) higher than dry land rice (0,76 individu/ m2). Meanwhile, average population density in the light month (0,94 individu/ m2) higher than in the dark month (0,77 individu/ m2).

Abstract

ABSTRACBivalve is one of fisheries products having essential value as a source of food.  It is caught in a variety of type sand sizes. Polymesoda bengalensis is a regarded as filtration feeders and detritus feeders. Filtration feeders refine plankton from the waters around, while the Detritus feeders make use of organic materials from plants falling down to the bottom of the water. This research was   designed for revealing the natural forage given to the cultivation of Polymesoda bengalensis. This cresearch was conduced in January 2013 to analyze Polymesoda bengalensis bowel in Muara Nipah Kecamatan Sutera Kabupaten Pesisir Selatan. To conduct the research, survey Descriptive method was applied. The sample was was chosen by using Random Sampling method. The numbers of the sample analyzed was 30 in which the length of the bivalves bodies were < 30 mm, 30-50 mm, and > 50 mm. There were 10 bivalves taken as the representation of each size.Based on the result of data analysis, Detritus and 12 genus of Phytoplankton were found in the Polymesoda bengalensis bowel. Detritus was the most dominant natural forage found in the bivalves bowel. The frequency of its existence was 100%.   In the bowel of bivalves of <30 mm length, Detritus was the most dominant food found (49,465) followed by Synedra (8,6%). In the bowel of bivalves of 30-50 mm length, the food found was dominated by Detritus (47,77%) followed by Synedra (10%), while in the bowel of bivalves of > 50 mm length, the food found was dominated by Detritus (39,13%) follwed by Cymbella (10,43%). Based on the preference viewed from the Largest Index, the natural forage for the bivalve of < 30 mm length, Oedogonium and Detritus were considered as the main food, meanwhile, for the bivalve of > 50 mm length, Detritus was as the main food. Based on the result of data analysis, it was revealed that the main forage for Polymesoda bengalensis was Detritus and Oedogonium.
