Abstract

The monitoring technic  using  aquatic  organism  as bio indicator was  more  advance.    Monitoring of  water  quality conduct   with  biological indicator among   macrobentic biomass  and  green  mussel  population were  intensively used  by researcher. These research was consider  that  water  quality damage on Jakarta  bay might be identity with biomass analysis approach.   Benthic  organism used as sample  were  macrozoobenthos and green  mussel (Pema viridis).  Water  quality was analysed  using  Fsawb  (Fish and Wild  Life Method) index  from  ott. 1979, then  for  biomass  model  was analysed  by dominant cumulative curve.   Result  of this  research  showed  that  Fsawl index  average  was 64.99, that  its  value  was unappropriate for fishes.   The analysis  of abundance and biomass  comparison index  was tend  to increase  the  density, while the biomass was decrease.   The results  indicate that  water  body  was  already  polluted.  The si:: nificant  impact for  mussel of  pollution was appear on water column at 2 m under of sea level.Key word: Macrozoobenthos,Pema viridis, Water Quality Index,Biomas dan Abundance Index,Jakarta Bay

Abstract

Pineapple is one of the potential export commodities in Indonesia. The objective of this study is to analyze the competitiveness of pineapple export of Indonesia based on its market share and to examine factors affecting it. The time series and cross section data are estimated by panel data regression. The results show that the competitiveness of Indonesia is lower than others main producers and exporters with the trend of market share is decline. The results also show that export quantly, Gross Domestic Product (GDP) per capita and production quantity are important factors affecting the competitiveness of pineapple export of Indonesia. The results indicate that the export and prodution quantity are positive to market sahre, whereas GDP per capita is negative.

Abstract

Food borne diseases by microganism was still happened as a lot of cases per annum. Sources of food microbiological contamination were raw materials, personal hygiene, sanitary of equipment and airborne and water sources. The goal of this research was to sources of food microbiological contamination in five restaurant around IPB campus which sould “pecel ayam”. Microbiological testing was conducted by total plate count, most probable number of coliform and biochemical identification of salmonella sp. And escherhicia colli. Personal hygiene and sanitaryof water and equipment testing have been done to detect sources of microbiological contamination. Food without heat teratment (cucumber) has a large amount of microganism (2.9-6.8 log CFU/g) and coliform (2.5-3.7 log MPN/g). smoked and fried chicken have total microoganism under 1.4 log CFU/g and total coliform under 0.3 log MPN/g. Sambal have total microoganism between 1.4-4.1 log CFU/g and total 0.3-4.1 log MPN/g. Neither Entorocbater aerogenes, nor Escherichia coli, the bacterium cold occasionally cause gastroenteritis, was identified from all of the smoked and fried chicken. E. coli has been isolated from cucumber of RM3, and the best possibility source of this bacterium was water source. Source of Entrobacter aerogenesis which identified from cucumber and sambal were personal handed, talenan and water source. Salmonella has not been identified from the entire sample.

Abstract

Sponges are host organisms for various symbiotic microorganisms.  Various symbiotic microorganisms have been found in Sponges such as archaea, heterotrophic bacteria, cyanobacteria, green algae, red algae, cryptophytes, dinoflagellates, and diatoms. The objectives of the research were to isolate and identify teh Axinella sp. Sponge-symbiotic microoganisms such asbacteria, micro fungi, and yeast. Sponge-symbiotic microoganisms that have been isolated cosisted of 7 bacteria isolates, 3 micro fungi, and 2 yeast isolates. Result from this research showed that the genus of bacteria was Alteromonas, Bacillus, and 2 yeast isolates have not been to identified.

Abstract

The main objective of the study is to identify why soil conservation that believed giving more benefits Is not adopted by upland potato’s farmer of pangalengan, Bandung. The study was carried out in pangalengan subdistrict, Bandung. Population of responden is 1148 farmers. Respondent of 180 farmers (15% of population) was drawn randomly from 13 village. The respondent amount of each village was drawn proportionally. The study reveals long term (20 years) and short term (one period of cultivation) impact of three farming systems using an approach of farm income analysis. Two of three farming systems apply soil conservation practices, bench terraces and contour farming systems, while the other does not apply soil conservation practice (slope farming system). Short term of farm income is quantified by using input and revenue prices 2004-2005. Long term of farm income is quantified by using SCUAF (Soil Change Under Agricultural Agroforestry and Forestry) model and Cost Benefit Analysis. In one period of cultivation (short term), farm income of slope farming is higher than farm income of soil consservation practices, benc terraces and contour farming. In 20 years, NPV of bench terraces and contour farming systems is higher than NPV (Net Persent Value) of slope farming system. The long term benefit of soil conservation practices causing farmer reluctant to adopt conservation practices. Soil conservation practices implementation in the future needs supported by policy how to make the long term benefit of conservation is more interesting to farmer such as giving incentive or credit to farmer who adopt soil conservation practice, and as well as the certainty of land holding.

Abstract

The aim of this study was to explore IgY anti Streptococcus mutan production and the ability of Igy Streptococcus mutans blocking adhesion process. The eggs was collected from Single Comb Brown Leghorn which have been immunized by S. mutan. Agar gel precipitation test was done to detect IgY anti S. mutans in serum and egg. Egg which Countain IgY anti S. mutans was collected. IgY anti S. mutans extracted from egg yolk by mean s PEG-Amonium sulfat and purified using fast protein liquid chromatography. The purity of Igy anti S. mutans was determined by UV spectropometer. Biological activities of Igy anti S. mutans to inhibit adhession process was learned by anti adhesion test. We use two dose of IgY, which is 100 ug and 500 ug. Igy anti S.  mutans formen in serum  five weeks after the first immunization while it formed in egg nine weeks after the first immunization. Igy anti S. mutanss still present in serum andegg until twelve weeks from the first immunization. Igy anti S. mutanss  could decrease the amount of bacteria which attach the epithelial cell surface. The amount of sticky bacteria on epithelial cell (without IgY) are 40 cell bacteria/epithelial cell. After blocked by IgY anti S. mutanss  the amount of bacteria turn into 30 cell bacteria/epithelial cell (for dose of 100 ug IgY) and 28 cell bacteria/epitheelial cell (for dose of 500 ug IgY). This research concluded that hens were capable producing IgY anti S. mutanss in egg yolk and it can be used to solve dental caries problem which caused by S. mutanss.

Abstract

Agricultural lands not only produce food and fibre, but also generate social and economic services such as job opportunities, rural culture preservation, and food security, as well as environmental services such as flood mitigation, erosion and sedimentation preventions, water resource conservation, and biodervesity. The services are called multifunctionality. The out put of multifunctionality is public goods since the beneficiaries are not only farmers but also the publi at large. The value of environmental services produced by farmers, in general, is not accoundted in the current market mechanism, and in most casses is ignored in the policy making. This condition leas to lack of attractiveness of farming, which subsequently leads to conversion of agricultural lands. This paper presents research results on economic valuation on the multifunctionality of agricultural lands, particulary paddy fields and upland farming in Citarik Sub Watershed, Bandung District, West Java. The reulsts showed that using replacement cost method (RCM) the economic value (EV) of paddy fields and uplands were Rp. 55.4 million and Rp. 9.9 million/ha/year. Repectively. The EV of paddy fields consisted of environmental services (71.4%) and marketable products (18.6%). It means that farmers had provied free of charge environmental services to the society. The community’s knowledge on multifunctionality of agriculture based on interview ws still low. Around 66% of respondents recognized only one to two agricultural multifunctionality aspects.
