Abstract

This research aims to determine the presence of endophytic bacteria producing catalase enzyme in Buasbuas (Premna pubescens Blume) leaves and how endophytic bacteria producing catalase enzym characteristics of the Buasbuas (Premna pubescens Blume) leaves. This research was conducted with several characterization stages: macroscopic characterization (morphology), microscopic characterization (gram staining) and catalase test. Data analysis technique used is descriptive. The isolation result there are 5 isolates of endophytic bacteria and 3 isolates which have potential to produce catalase enzyme.

Abstract

The purpose of this study was to determine the effectiveness of some antiacne facial cleanser products against bacteria that cause acne Propionibacterium acnes, which conducted experimentally using 6 product against of antiacne facial cleanser bacteria cause Propionibacterium acnes with three replication. The parameters observed were the inhibitory zone diameters. The results showed that of some antiacne facial cleanser products that are most effective in inhibiting the growth of acne-causing bacteria Propionibacterium acnes is the product CCA code, with a 35 mm inhibit zone, because CCA products were contain 6 combinations of natural ingredients from Hamamelis virginia, Melaleuca alternifolia, Cinnamomum zeylanicum, Cedrus atlantica, Portulaca oleracea and olive oil All antiacne products are shown to have effectiveness against the bacteria Propionibacterium acnes.

Abstract

Tanipah village is a coastal village in Kecamatan Aluh-Aluh, Kabupaten Banjar, Kalimantan Selatan and a tidal area of sea water. Tanipah villagers utilize river water for daily needs, so the quality of river water is a major concern. The results of this research are expected to be informations for the community about quality of river water in Tanipah. This research is a survey research and the analysis was conducted in-situ and ex-situ. The analysis was done by comparing the test result against the predefined quality standard. River water temperature in Tanipah ranges from 280C – 33,60C and has no taste and no smell. Turbidity of 54,8 NTU, indicating river water is not feasible for consumption. Dissolved oxygen is 5,9 mg/L and is in the mild contaminated category. The COD and BOD value respectively 17,03 mg/L and 6,70 mg/L, exceeds the limit of the class I water quality standard. The pH value is at 7,33, indicating that the pH is normal. The iron concentration is 1,71 mg/L, exceeds the maximum permissible level for drinking water quality. Other metals likes Mn, Pb, Cu and Cd, are within thresholds for the waters. River water in Tanipah village based on the value of dissolved oxygen, is in category of light contaminated. Thus, in general, river water in Tanipah village can only be used for class III water, as irrigation.

Abstract

The aim of the study was to isolate lactic acid bacteria (LAB) from palm oil sap and to investigate the anti microbial activity of LAB against pathogen bacteria, Staphylococcus aureus and Escherichia coli using disc diffusion method. Palm oil sap were enriched using spesific medium MRS (Man Rogosa Sharpe) broth overnight, serial dilution were conducted and the culture were spread on the surface of MRS agar and then incubated for 48 hours. The result showed the total colonies of LAB were 1,4 x 107 CFU/mL. 6 colonies were randomly selected namely EHN1, EHN2, EHN3, EHN4, EHN5 and EHN6. The selected colonies are classified as Gram positive and bacilli in morphology. Antimicrobial activity against pathogenic bacteria was investigated using disc diffusion method. Antimicrobial activity of isolates against E.coli and S.aureus were 12,2 mm; 9mm; 11mm; 11mm; 10,5mm; 12 mm dan 13,5mm; 11mm; 12mm; 11,5mm; 12mm; 12,5mm respectively. from these result it can be concluded that LAB isolated from oil palm sap has potential as probiotic.

Abstract

Diabetes Mellitus is a health issue that attracts a lot of attention because of the prevalence rate that increases every year, especially in developing countries like in Indonesia. Diabetes Mellitus (DM) is a condition of decreasing the function of the pancreas to produce insulin or insulin receptors are not sensitive so that a metabolic disorder occurs where glucose is not converted into glycogen so that glucose can not enter the cells, resulting in increased blood glucose. Simalungun ethnic is one of the ethnic group in Simalungun Regency of North Sumatera Province where the society of Simalungun ethnic still utilize herbs as an alternative treatment like diabetes mellitus, so it is necessary to do research about the Utilization of Diabetes Mellitus Medicinal Plants In Simalungun Ethnic Society of Simalungun Regency of North Sumatera Province. This research was conducted using exploratory survey by the independent variable informant. Data collection was done by in-depth interview technique to informant. The results obtained 26 species of plants, consisting of, 20 families and 15 orders that have potential as an antidiabetic drug. Plant parts used are roots, leaves, fruit, stems, bark, seeds and tubers. And the most widely used is the leaves as much as 40.74%.

Abstract

Sangkuriang catfish (Clarias gariepinus var Sangkuriang) is the main commodity that widely cultivated in Tasikmalaya City. However, farmers have difficulty because of the disease which causes death in fish. High mortality is suspected as a vibriosis disease by genus Vibrio because redness wounds on dead fish. The purpose of this study is to know the genus Vibrio which causes of disease in Sangkuriang catfish. 10 samples of fish were taken from Sangkuriang catfish pond culture in Kelurahan Kersanagara Tasikmalaya City which were potentially suspected of vibriosis disease. Isolation of bacteria were done on TCBS medium. Bacterial isolates were collected from fish lesion on the body surface, liver, and kidneys of catfish. Isolation were able to gained 21 isolates and then 5 isolates (VK1, VK5, VK7, VK17, and VK21) were selected based on colony morphology and Postulates Koch’s were tested. The results showed that the clinical symptoms of catfish infected by vibriosis were redness lesions/ulcers on the body surface, hemorrhagic, fluid inside stomach, and fin eroded with redness wound. Bacterial identification through biochemical test revealed the causative agent of catfish disease at brackish pond area were bacteria of the genus Vibrio (VK 1, VK 5, and VK 7), Vibrio vulnificus (VK 17 and VK 21).

Abstract

The aimed of this research was to investigated human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri), to investigated dose of tartrazine, and to investigated biotransformation of tartrazine by human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri). The method of this research was experiment with significant correlation to investigated biotransformation of tartrazine by human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri). This study is primarily focussed on made bacteria medium, made standart inoculums of bacteria, and evaluation for activity of human intestinal bacteria (Streptococcus faecalis, Eschericia coli, Salmonella Sp., and Vibrio fischeri). The results obtained were attributed to the human intestinal bacteria was used in this research was biotransformated tartrazine. From the results that had been increase dose of tartrazine correlation with increase biotransformation by human intestinal bacteria. Highest dose of tartrazine was 15 mg, and highest biotransformation by Vibrio fischeri, which rate of zone decolourisation diameter was 1,22 cm, and rate of zone decolourisation was 1,44 cm2. Statistically showed significantly in correlation dose of tartrazine with rate of zone decolourisation (0,001 < P < 0,05), but statistically showed non significantly in correlation bacteria with rate of zone decolourisation (0,05 < P < 0,268).
