Abstract

Turmeric (Curcuma domestica Val.) has many health benefits and can be used in herbal medicine as well as traditional herbal drink. Turmeric can also be used as a natural dye in food. Turmeric is very perishables in a fresh state, thus drying process is needed to extend its shelf life. An environmentally friendly drying using Solar Tunnel Dryer (STD) is one of the techniques that is interestingly developed. The purpose of this study was to determine the effect of steam blanching at different times (3, 5, and 10 minutes) and soaking using a 0.05% citric acid for 5 minutes on the physicochemical and microbiological qualities of turmeric dried by STD. Measurements were conducted to analyze water content, water activity, curcumin content, antioxidant activity, pH, water activity, color intensity, and total fungi. The results showed that steam blanching and immersion using a 0.05% citric acid for 5 minutes could reduce the drying time when compared to that of control. While 5 minutes of steam blanching with immersion in the 0.05% citric acid for 5 minutes could produce a high antioxidant activity which was 80.30 ± 0.89 (% inhibition) and it had the lowest total fungi which were 3.33 ± 5.00%

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).

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

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

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.

Abstract

Mealybug can almost be found in all pineapple fields (Ananas comosus (Linnaeus)). The insect is known to be a vector of Pineapple Mealybug wilt-associated Virus (PMWaV). The insect samples taken from pineapple in Bunihayu, Jalancagak, Subang, West Java, were identified in laboratory. Mealybug-ant symbionts were also taken. The ability of this ant to carry the mealybugs from colony reared on kabocha (Cucurbita maxima) to pineapple was also tested at green house level. Only one spesies of mealybug was found on pineapple, i.e. Dysmicoccus brevipes (Cockerell) (Hemiptera: Pseudococcidae). The mealybugs were found to colonize root, basal of stem and the leaf. Eight ant species were found to be associated with mealybug. There are four species belongs to Pseudolasius genera, two species Cardiocondyla genera, Paratrechina sp. and Dorylus sp. Paratrechina sp. showed the ability to carry D. brevipes from kabocha population to pineapple. Therefore the ants should also be controlled in the total management of PMWav.

Abstract

Antioxidant has an important role in healing some kind of dieses caused by excessive oxidation reactions in human body. That leaf has benefit to resist diarrhea, anti inflammation, and anti mutagenic. It is assumed it could be used as antioxidant. The research was aimed to know the antioxidant activity of the extract of Psidium guajava leaf. The local leaf was from Bantar Kambing area in Bogor. The methods were thiocyanate method and thiobarbituric acid (TBA) method. The result showed that the leaf wich had the best antioxidant potential was the white local Psidium guajava leaf extracted by ethanol 70% in a maceration manner. In the tyochianate method, the extract of white Psidium guajava leaf had protective factor near to Vitamin E or tocopherol, that is 1.10 and tocoferol was 1.16. antioxidative evaluation using the TBA method showed that the highest activity was from ethanol extract of white  Psidium guajava leaf could obstruct it up to 94.19% toward the control, however the actif constituents are unknown. Phytochemical evaluation result showed that the Psidium guajava leaf are contained tannin, phenol, flavonoid, quinon, and steroid.

Abstract

The purpose of this study was to examined the effectivity of Aloe vera gel formulation on the skin wound healing process based on the macroscopic and microscopic observation. Fourty five DDY strain, 6-8 weeks old mice were used for experimental animals. Mice were incised 1-1.5 cm in the dorsum using sterile scalpels. Mice were divided into three groups. Group I (control) were not treated by anything, Group II were treated by commercial drugs (Bioplacenton), and Group III were treated by Aloe vera gel. Bioplacenton and Aloe vera gel were given topically twice a day to the skin using sterile cotton buds. Each groups consisted of 15 mice and distributed into 5 observation days with 3 replication. Three mice from each groups were euthanized periodically at day 3rd, 5th, 7th, 14th, and 21st post incision for gross pathology examination and to sampling the skin. Gross examination revealed that Bioplacenton and Aloe vera gel showed better result on wound healing process, i.e. the scab formation, scab peeler and unite of the wounded skin edge compared to the control groups. Microscopically, the Bioplacenton and Aloe vera gel groups showed the fastest epidermal re-epithelization compared with the control group. Qualitatively Bioplacenton and Aloe vera gel groups showed more fibrosis and collagen fibres formation than the control groups especially at day 7th and 14th. Scoring Average of neocapillaries formation from all groups showed no difference. Scoring average of inflammatory cells number revealed that control groups showed more cells than the other groups that indicated an high inflammatory activity. Based on macroscopic and microscopic examination we suggest that the Aloe vera gel formulation has a benefit to promote wound healing, and could be used for the treatment of skin wound. Thus, the Aloe vera gel formulation is potential to developed as commercial drugs.
