Abstract

Inadequate quality of food products that do not meet standard quality may lead to food poisoning cases and become a concern in public health sector. Nasi Jinggo is a small amount of cooked rice with little bit fried tempe, shredded spicy chicken, traditional made chili sauce that is packed with banana leaves, and all the cooking process usually done traditionally. Nasi jinggo is sold at night by street vendor with price ranged from Rp. 1.500,- to Rp. 2.000,- per package. The study was a quantitative descriptive study with cross-sectional design that was aimed to identify the microbiology quality of nasi jinggo that were sold in Denpasar Selatan area. From 48 population of nasi jinggo street vendor, 23 vendor was taken as samples. The microbiology quality being assessed was Total Plate Count (TPC), Total Coliform with MPN method and Escherichia coli content with Eosin Methylene Blue Agar as medium. Laboratory analysis showed that only 21,7% sample that met TPC standard with average value of 2,3 x 107 CFU/gram sample, only 8,7% that met Total Coliform standard with average value of 1,4 x 105 MPN/100 gram sample and 52,2% sample that met E. coli content standard with average value is 2,6 x 102 MPN/100 gram sample. It is recommended to the government to do quality check towards nasi jinggo in a regular basis as well as to provide education and assistance to nasi jinggo street vendors in order to improve the microbiology quality of food product and ensure food safety to the consumer.

Abstract

Fermented food was produced in both traditional and modern techniques, to increase fungtional value and taste.  One example is Red Mold Rice (RMR) or Angkak, which is famous fermented rice from China. RMR was made from rice, red fungi Monascus purpureus and Monacolin as metabolit seconder, which believe can reduce Cholesterol dan trigelseride. Oral treatment with Cholestyn (1,2 g/d) can reduce LDL (bad cholesterol) up to 30,9% and triglesirida up to 34,1%, and can also increase HDL (good cholesterol) by 19,9%. Beside Monacolin, RMR also contains Cytrinin (0,2-122 mg/kg) which has a negative impact on functional and structural of human kidney and liver.

Abstract

An exploration study of natural resources soil bacteria antibiotic-producer, Streptomyces spp. was done in two steps. The first step was isolation of Streptomyces and the second involved testing their inhibition activities against five strains diarrheagenic Escherichia coli. Soil samples were collected from ten forest areas in Bali. As many as 55 isolates were collected with various macroscopic dan microscopic characters. Most isolates (eight Streptomyces isolates) were collected from forest area in Penulisan, Kintamani (RTK. 20). The diversities of isolates are influenced by environment condition. All Streptomyces isolated were tested against five strains diarrheagenic Escherichia coli to check antibiotic activity for inhibit growth of E. coli. Streptomycine was used as a control. The result showed that the largest inhibition zones of Streptomyces against E. coli strains EHEC, ETEC, EIEC, EPEC and DAEC were produced by Streptomyces PK5 (48,67 ± 0,58 mm), Streptomyces GAA4 (29,00 ± 2,00 mm), Streptomyces GBK3 (42,67 ± 2,08 mm), Streptomyces SkBB5 (29,00 ± 2,65 mm) and Streptomyces GM3 (33,67 ± 3,21 mm) respectively.

Abstract

Bali has the potency to grow plantation, particularly cacao plants (Theobroma cacao). The increase of cacao production is supported by the increase of the number of productive cacao plants, but the production rate per hectare per year decreased at some districts. One reason of the decreasing cacao production was due to the attack of Plant Disease Organism. This research aimed to investigate the insect families associated with cacao plantations and the fuctions of the insects on cacao plants, at Bedulu Village, District of Blahbatuh, Gianyar Regency. Samples were collected from January to February 2011 and insect identification was conducted for two months at Animal Taxonomy Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Udayana University. Field sample collections were arranged by randomized sampling techniques that the block samples were chosen randomly. Samples were collected with beating technique and trapping with sex pheromone. All insects collected from the field belong to eight groups/types. The highest percentage of insect type collected fuctioned as vector (56.1%) and the lowest was acted as parasites (0.1%). The highest number of two groups insects captured were groups of pests and predators. The insect that function as biological control was the family of Labiduridae, Anthocoridae, Reduviidae, Chrysopidae, Gryllidae and Chalcididae.
