Abstract

The study of "The Effect of Different Starter Dosage to Organoleptic Value of Kefir Cow Milk Products" was carried out from May to July 2016 at the Microbiology Research Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University, Padang. The purpose of this study was to determine the organoleptic value (aroma, taste and organoleptic) of cow's milk kefir products from three different starter doses, and the results were with Wilcoxon Level Test. The results showed that organoleptic assessment of the aroma of cow milk kefir products with a treatment dose of 15% starter (3.00) was the most preferred dose for the panelist, while kefir with a treatment dose of 5% (2.27) is a dose that is less preferred by panelists. The taste assessment of the organoleptic of cow's milk kefir products, the starter dose of 10% (2.87) was the most preferred by the panelists, but the dose of 15% (2.33) was the least. Similar to the taste, the consistency of cow milk kefir with the dose of 10% (3.07) was most preferred, while the dose of 15% (2.33) was least preferred by the panelists.

Abstract

One of the diseases that attacks poultry especially laying hens (Gallus gallus domesticus) is colibacillosis, a disease caused by Escherichia coli. E. coli is a bacterium that has opportunistic properties, which is normally present in the digestive tract in a controlled amount, but when the condition of the chicken decreases, it can develop into pathogens. Kidneys are organs that are vulnerable to substances that are toxic and are also susceptible to bacterial infections. This study aimed to determine the histological structure of kidneys of laying hens (Gallus gallus domesticus) who died due to the infection of E. coli. The research was conducted at a Pathology Laboratory (BBVet), Denpasar. The hen’s kidneys were processed with the paraffin method and Hematoxylin-Eosin staining. Cell damage that occurs is observed by using the Image Raster application. The data obtained were analyzed with the scoring method. Renal histopathology parameters can be seen in the form of degeneration, necrosis, congestion, and inflammatory cell infiltration. The results obtained cell damages namely 46% of degeneration, 60% of necrosis, 44% of congestion and 76% of inflammatory cell infiltration.

Abstract

This study aims to determine the effect of ethanol extract of Kedondong leaves (Spondias dulcis G. Forst) on the gastropathological histology of white rats (Mus musculus). A total of 25 healthy male white rats with weights 200-250 g were randomly divided into five groups. A control group was only given a placebo. The treatment group of kedondong leaf ethanol extract sequentially with a dose of 125, 250, 500 and 1,000 mg/kg/day for 21 days orally. On the 22nd day all of the animals were sacrificed for its the gastric, followed by processing for histopathological preparations with Hematoxylin Eosin (HE) staining. The results of the study in all treatment groups were found gastric histology changes in the form of mild inflammatory cell infiltration, mild fatty degeneration and mild necrosis. The number of mice that experienced histopathological changes differed in each group. It can be concluded that the oral administration of kedondong leaf ethanol extract with a range at a dose of 125-1000 mg/kg/d for 21 days does not cause significant histopathological structure disturbance in the stomach of male white rats.

Abstract

The intensive farming of vannamei shrimp in Patas village release waste that affected the water quality for seaweed cultivation. The aims of this study were to investigate the effects of shrimp pond waste to water quality and growth of seaweed Eucheuma spinosum in Patas village. The research located in Patas village, Gerokgak district, Buleleng regency, Bali province, during the plantation cycle (45 days) from July to September 2017. The collected data consist of total N, total P, Nitrate (NO3-), Ammonium (NH4+), and Phosphat (PO43-). The results showed the average weight of seaweed near the shrimp ponds was 5.85% g with 0.15% g increment, while at the far location from shrimp ponds was 7.05% g with 0.41% g increment. Its indicated that the Eucheuma spinosum cultivated in far location has a better yield than the near location from shrimp ponds. The Chlorine content in shrimp pond waste affecting the seaweed growth and water quality, such as salinity, pH, DO, Nitrate, and Phosphat.

Abstract

Green grass jelly (Cyclea barbata Miers.) is known for its benefit to human health especially in supporting body’s immune system and wellness. This research aimed to determine immunomodulatory and antioxidant activity of green grass jelly leaf extracts in vitro. Old leaves were collected as sample then dried and ground to powder. The extraction was done with sohxletation using three different solvents, chloroform, ethyl acetate, and ethanol. The immunomodulatory activity was evaluated by treating the crude extracts at concentrations of 50, 100, and 500 mg/mL on macrophages of rat in vitro. The treated macrophage was then challenged for their phagocytic activity to latex beads. The antioxidant activity was done using 1,1-diphenil-2-picrilhydrazil (DPPH) with spectrophotometry technique. All treatments were done with three replicates. Detection of the bioactive groups of the extracts was done by Thin Layer Chromatography (TLC). The results showed that ethyl acetate extract has the highest phagocytic activity followed with chloroform extract and ethanol extract, respectively. Optimum concentration was reached at 100 mg/mL of ethyl acetat extract. The ethyl acetate extract was also the extract with the highest antioxidant activity index 7.7 followed by both extracts of chloroform and ethanol with similar index value of 6.25 and 6.3, respectively. The ethyl acetate extract contained phenolics, flavonoids, tannins, and terpenoids.
