Abstract

The  study aimed to determine the effect of chitosan on  the kidney of rats (Rattus sp.) exposed to lead acetate. Thirty five male animals weighing 250g were divided into 7 groups:  K group as a control (without treatment), P1  received  Pb (40 mg/kg bw as lead acetate),  while P2, P3, and P4, all received Pb (40 mg/kg bw) and chitosan (0,5%, 0,75%, and 1% respectively). P5 group received only chitosan (1%) and P6 group received acetic acid. After 7 weeks of  treatment, the animals were sacrificed and the kidneys were isolated. Kidney damage was observed with microscopis. Result showed, treatment of Pb (40 mg/kg bw) in male rats caused demage microscopis. Chitosan able to decrease kidney damage resulted from Pb treatment. In conclusion, chotosan has the ability to reduce residue of Pb as well as microstructure damage of rat kidney exposed to Pb.

Abstract

Copper pollution in the East Coast of Surabaya is one of the serious cases of heavy metal pollution in Indonesia. Pollution at this location has been proven to result in fish deaths and brain damage of local residents because they consume too much copper-contaminated fish. Copper bioremediation using indigen bacteria isolated from polluted environments is a promising solution to overcome copper pollution problems. Bacteria that commonly live in polluted environments can be isolated and used as copper bioremediation agents. This study aims to do: 1) isolation and characterization of copper resistant bacteria from the East Coast of Surabaya, 2) resistance testing of bacterial isolates, and 3) copper accumulation and biosorbtion tests of bacterial isolates. The bacterial isolates were characterized by the morphology of the colonies and their cells based on Gram staining. Resistance testing is done by determining Minimum Inhibitory Concentration/MIC. The accumulation test is carried out by separating the cell and growth medium, then each of them is distructed using HNO3. The results of isolation and characterization obtained six isolates of copper-resistant bacteria, namely PmbC1, PmbC2, PmbC3, PmbC4, PmbC5, and PmbC6 with MIC = 3 mM - 5mM CuSO4. PmbC4 isolate is the most resistant bacteria with the MIC of 5 mM and is capable of accumulating copper of 6.25 mg per gram of cell dry weight and biosorbtion of 92.17%.

Abstract

This reseach was conducted to determine the antibacterial activity against Staphylococcus aureus and Eschericia coli from pandanus fragrant ethanol extract formulated in the form of hand gel antiseptic preparations. The ethanol extract was prepared by percolation using 96% ethanol solvent. Phytochemical screening is done on fragrant pandan leaves. Evaluation of hand antiseptic gel preparations included organoleptic testing, homogeneity testing, pH determination, spreading test, stability, irritation testing and antibacterial testing of Staphylococcus aureus and Eschericia coli. The results of phytochemical screening showed that the pandanus fragrant leaves contain alkaloids, tannins, saponins, flavonoids and polyphenols. The pandanus fragrant leaves ethanol extract can be formulated into hand gel antiseptic preparations because the pH is about 6.0-7.1, the spreading power is about 5.06-5.15 cm, stable for 12 weeks and organoleptically a formula with a very 2.5% concentration Favored and does not irritate the skin. The results of antibacterial activity test showed that the preparation with concentration of 10% had the strongest activity with the diameter of 13,23 mm to Staphylococcus aureus and 13,13% to Eschericia coli almost same with dettol stock on the market with diameter 16,43mm to Staphylococcus aureus and 16 , 03% against Eschericia coli.

Abstract

This research aims was to analyze the potential of activated charcoal leather cassava in the adsorption process linear compounds alkilbenzene sulfonate (LAS) contained in the liquid waste household detergents. Stages of the study consisted of charcoal formation process of the skin of cassava through the combustion process of pyrolysis, charcoal leather activation process cassava, and the compound adsorption process linear alkyl sulfonate (LAS) contained in the liquid waste household detergents. The results showed that activated charcoal is formed from leather waste cassava LAS have the ability to adsorb the compounds contained in domestic wastewater. Treatment optimum adsorption occurs at a concentration of activated charcoal leather cassava 4 grams and a contact time of 20 minutes.

Abstract

Lactic acid bacteria (LAB) could be isolated from various fermented food products. One potential source of LAB is traditional fermented food. The aim of the study was to isolate and investigate antimicrobial activity of LAB isolated from traditional Batak food, “naniura”. The LAB isolates were characterized by Gram staining, fermentation type and catalase test. The investigation of antimicrobial activity of LAB against pathogenic bacteria were conducted using disc diffusion method. The results showed that 6 isolates of BAL were successfully isolated namely BN1, BN2, BN3, BN4, BN5 and BN6 had characteristics of Gram positive, rod shaped and catalase negative. All selected isolate have heterofermentation type. Four isolates (BN1, BN2, BN5 and BN6) were able to inhibit S. aureus, E. coli and S. typhi with inhibition zone diameters ranging from 6,9 to 12,3 cm. Based on the result, it was concluded that LAB isolated from naniura has potential as a source of probiotics.

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).
