Lactobacillus sp F213 (LbF213) is a lactic acid bacteria isolated from a healty infant feces, which has been proven as a probiotic bacteria because it is resistant to low pH, bile salts, digestive enzymes, able to survive and colonize the intestine, and prevent infection from E.coli pathogens.This study was conducted to know the viability of Lactobacillus sp F213 probiotic bacteria in rice juice during cold storage and its effect on the characteristics of rice juice products. This study used a descriptive method in objective tests (total lactic acid bacteria test, total glucose, pH and total acid) and a complete randomized design method in the subjective test (sensory test). This study used two treatments, namely rice juice with the addition of Lactobacillus sp F213 and without the addition of probiotic bacteria which are then tested every 3 days of 0, 3, 6, 9 and 12 in cold temperature. The test results data presented in the way form of tables and figures. The results of this study indicate that the viability of Lactobacillus sp F213 to 12 days storage at cold storage temperatures. The addition of Lactobacillus sp F213 also tends not to affect the characteristics of rice juice during storage either from the results of pH, total acid and total glucose and from sensory characteristics such as color, aroma, taste and overall acceptance. Keywords: probiotics, rice juice, viability, Lactobacillus sp F213

“Jamu Gendong Kunyit Asam (Tamarind Turmeric Sour Herbs)” is a typical Indonesian drink that is quite famous which is one of the legacies of the Indonesian nation’s ancestors who have medicinal properties in maintaining health and for healing a disease. This study aims to determine aspects of chemistry and microbiology as well as food safety of Tamarind Turmeric Sour Herbs in Jimbaran and Kedonganan, Bali by using survey method and research. The observed variabels include total microbial, coliforms, Escherichia coli, pH, total acid, total vitamin C. The results of microbiological aspect test in this study showed that two samples of Jamu Gendong Kunyit Asam (Tamarind Turmeric Sour Herbs) at Jimbaran and Kedonganan,Bali does not meet the requirements according to SNI 7388:2009 namely samples B and E with indigo in sample B that is 30 x 10-1 and sample E which is 1 x 10-1. The result of chemistry aspect are if the increase in total vitamin C will effect the increase in total acid and pH will be more acid. Besaide that, E. coli bacteria can grow at a pH of 5-7 and the compound content of the tamarind fruit is also antibacterial so that most of Jamu Gendong Kunyit Asam (Tamarind Turmeric Sour Herbs) at Jimbaran and Kedonganan are not contaminated with E.coli.

Pesticides are chemical substances used to control various pests and diseases. In the field, synthetic pesticides are widely used and their use is not controlled and exceeds the permitted threshold according to the Minister of Agriculture No: 88 Permentan/PP.340/12/2011. The purpose of this study was to determine the content of pesticide residues in vegetables cultivated in Badung district. A total of 16 types of vegetables with 32 samples were tested for pesticide residues of organophosphorus and organochlorine groups (Diazinon, chlorphyrifos and Profenopos) on vegetable crops in Badung district. Qualitative testing was carried out with pesticide detection cards (Pesticide Detection Cards) and then samples contaminated with pesticides were continued by testing using Gas Chromatography Mass Spectrophotometry (GC MS) / The test results showed that as many as 30 samples of vegetables (93.75%) did not contain diazinon and as many as 2 samples (6.25%) containing diazinon, namely chinese cabbagge sample 1 of 0.015 ppm and chinese cabbagge of sample 2 of 0.024 ppm. A total of 29 samples of vegetables (90.63%) did not contain much chlorphyrifos and as many as 3 samples (9.37%) contained chlorphyrifos pesticide residues. A total of 30 samples (93.75%) contained profenofos and 2 samples of vegetables (6.25%) contained profenofos pesticide residues in the mustard greens sample 1 and chicory sample 2 were 0.048 ppm and 0.029 ppm, respectively. According to PERMENTAN No: 88 /Permentan/PP.340/12/2011, from the results of this test, all samples were below the Maximum Residue Limit (BMR) for pesticide diazinon, chlorphyrifos and profenofos

This research aims to find out the effect of fermentation time on the characteristics of soyghurt drink which was fermented by Lactobacillus rhamnosus SKG 34 and to identify the right fermentation time to produce soyghurt drink with the best characteristics. This research uses a Completely Randomized Design (CRD) with time of fermentation as the main factor that consists of 6 levels that are 0, 5 10, 15, 20 and 25 hours. Each treatment was repeated 3 times resulting 18 experimental units. The data were analyzed by analysis of variance (ANOVA) and if the treatment has a significant effect (P<0,05), then proceed with the Duncan Multiple Range Test. The results showed that the fermentation time had a significant effect on total LAB, total acidity, pH, aroma, sweet and sour flavor, overall accaptance, but had no significant effect on total sugar and color of soyghurt drink. The 5 hours fermentation time treatment produced the best characteristics of soyghurt drink, with the following characteristics: total LAB 9.47 log CFU/ ml, total sugar 9.64%, total acid 0.45%, pH 5.17, white color, with slightly sweet and sour taste, slightly liked aroma and liked overall acceptance.
