Abstract

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

Abstract

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.

Abstract

This research aimed to study the effect of extraction time on the antioxidant activity of rambusa leaves extracts extracted using the Microwave-Assisted Extraction (MAE) method. The extraction times were evaluated: 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes and 6 minutes with microwave irradiation power 300 Watt. This study used a completely randomized design with three repetitions to obtain 18 experimental units. The parameters observed included yield, total phenol, total flavonoids, total tannin and antioxidant activity. The data of yield, total phenol, total flavonoids, total tannin and antioxidant activity were analyzed by analysis of variance, and if the treatment had significant effect, then it was followed by the Duncan test. The results showed that extraction time significantly affected yield, total phenol, total flavonoids, total tannin and antioxidant activity of rambusa leaves extract. The results showed that 4 minutes extraction time was the best treatment, which produced a 17.40% yield, total phenol 75.07 mg GAE/g extract, total flavonoids 33.05 mg QE/g, total tannin 2.76 mg TAE/g, antioxidant activity based on free radical inhibition percentage 25.29 % and IC50 values 196.17 mg/L.

Abstract

Loloh is one of the traditional beverages in Bali made from fresh leaves, root, stem, seeds or fruit without cooking treatment (cold process). Some studies showed that loloh in several area in Bali is not worth to consume because of high level of microbial contamination. This study aimed to determine the effect of pasteurization time to produce loloh pohpohan leaves with the best antioxidant activity and free from microbial contamination. This experiment used a Completely Randomized Design with 7 variations of pasteurization treatment time, namely 0, 10, 15, 20, 25 30 and 35 minutes. The treatment was repeated three time for obtain 21 experimental units. The data obtained were analyzed by analyze of variance and if the treatment had significant effect, then it was followed by Duncan Multiple Range Test (DMRT). The result of this study showed that pasteurization time has a very significant effect (P<0,01) on total microbial, total coliform and antioxidant activity. The best loloh treatment in this study was obtain with 20 minutes pasteurization time with the total plate count 0 CFU/mL (no microbes showed), negative coliform and antioxidant activity 58.39% with IC50 valued 1584.097 ppm, the color is neutral, the aroma is neutral, the taste was bitter and neutral and overall acceptance is neutral.

Abstract

Indonesia as a tropical country has various kinds of fruit varieties. One of the famous fruits in Indonesia is guava. Guava fruit is popular with the public because it has a sweet taste. Ripe guava flesh can be processed into processed products such as jelly, jam, guava flour, fruit salad, fruit soup, chips, fruit juice, and fresh drinks. The benefits of guava fruit are many, such as being able to overcome several types of diseases such as diabetes, hypertension, and cancer. In addition, guava is also useful as an anti-bacterial, anti-fungal, anti-inflammatory, and can maintain skin health. Guava contains various vitamins and antioxidants that are beneficial for the body. The purpose of this study was to determine the content of vitamin C and antioxidant activity in guava juice added with cinnamon and brown sugar. This test uses 8 combinations of brown sugar and cinnamon treatments. The results showed that the best vitamin C content and antioxidant activity were found in the K2G0 treatment (4% cinnamon and 0% brown sugar) with a vitamin C content of 57,15 mg/100g and an IC50 value of 39,08 ppm.
