Abstract

Phanerochaete chrysosporium was known as white rot mold which could biodegrade persistent organic pollutants. In this research the ability of the mold in biodegrading textile dye direct orange S and rhemazol yellow, which contained naphtol functional group, was studied. This research included characterization of the waste water and determination of optimum concentration of the waste water for biodegradation. The optimum concentration for biodegradation was determined by measuring the radial growth of the mold in agar medium containing various concentrations of textile dye. The final stage was the application of the mold for biodegrading the textile dye in aerobic batch reactor using the selected concentration. This research showed that P. chrysosporium could grow satisfactorily in minimum medium containing synthetic textile wastewater in various concentrations. The highest colour removal efficiency of 93% was achieved in 3 days in the waste water with highest color intensity (absorbance value l520 = 4.00), and 48% in the waste water with absorbance value l520 = 1.22. COD removal efficiency of 87% was achieved within 12 days in the wastewater of 30% concentration, and 83% in the waste water of 100% concentration. The pH values decreased to 3.23 in the waste water with lower dye concentration and to 3.42 in the higher color intensity, from the initial values of 5.0-6.0. This research concluded that P. chrysosporium was capable to biodegrade naphtol textile dye with reasonably high efficiency.

Abstract

The study of secondary succession was carried out on Segara Anakan mangrove forest, since the secondary succession has been the significant problem in the mangrove forest Segara Anakan as the impact of illegal cutting and the neglected fishpond activities. Side-by-side comparisons method and quadrat sampling method were employed in this study. There were 3 areas of abandoned fishpond with different levels of succession. The sample stands were determinated subyectievely and the quadrat sample were put at random. Ordination method was used to see the correlation between vegetation pattern using environment parameters observed. The result of this study indicated that the important value on the stratum of mangrove herb was succession process. The ordination pattern of mangrove was not related to environment factors. In general, some spesies: Avicennia alba, Acanthus ilicifolius, Paspalum sp., Fimbristylis alboviridis, Bulbostylis puberula had the important role in the process of secondary succession.

Abstract

This research was an effort to reveal the effect of fruit juice of ‘labu siam’ [Sechium edule (Jacq.) Swartz] on total cholesterol and total glyceride of mice serum and also to reveal the secondary metabolites content of the juice. In this research, four groups of mice each consist of 8 was used. First group ws given normal food, the second group was given hyperlipidemic inducer. The third group was given hyperlipidemic inducer and fruit juice at dosage 0.546 mg/kg b.w. The third group was given hyperlipidemic inducer and fruit juice at dosage 1.092 mg/g b.w. The exogenic and endogenic hyperlipidemic inducers used were cholesterol suspension and propyl thiouracyl 0.01%, espectively. Both the inducer and the juice were given every day orally for three weeks. At the last day, the mice were fasted for 12-24 hours and the blood was collected intracardially. Assay of cholesterol and triglyceride in the sera was carried out using the reagent kits.Statistical analysis shows that the administration of the fruit juice of ‘labu siam’ at dosage 0.546 mg/g and 1.092 mg/g b.w. can decrease the triglyceride concentration in the sera. The dose 0.546 mg/g decreases the total cholesterol concentration, but the dose 1.092 mg/g did not show the sera cholesterol decreasing activity. Phytochemical screening for the constituents of the juice indicated that the juice contains saponin glycosides.

Abstract

This research was conducted in automotive workshop of VEDC Malang and the samples were taken at the automotive machine and automotive electric workshops. The parameters which examined were the Pb concentration in the mouse blood (Mus musculus) in 2 and 3 months years old. The measurement was run for 5 times every 10 days, and the result was mean value of the increasing rate of Pb concentration in the mouse blood. The aim of this research was to determine the increasing rate of Pb concentration in the mouse blood which has the relation with different working area, different age, and also duration of exposure. Based on the data of laboratory test, research continued by T-test analysis, Simple regression test, and correlation, and also General Linear Model. By doing statistic analysis with the different working area, duration of explanation, and different age.Result of this research showed that there were the differences of rapid increasing of Pb concentration in both workshop. Generally the age which influence so much for that (in the mouse body) and have the relation with the body stamina. If the mouse body absorb amount of Pb constantly, so the Pb concentration in it will increase more and more and it cause the decreasing of the body height.
