Abstract

Processed meat products are types of food that are easily damaged. Damaged to meat products due to the presence of microorganisms grew. To overcome this, meat processing companies have added a lot of food additives (BTP), namely sodium nitrite (NaNO2). Excess nitrite accumulation in the body can have an effect on the reproductive system. Research conducted by Pavlova et al. (2017) found that there was a decrease in epididymal weight and a reduction in the sperm count of rats exposed to high NaNO2. Eucheuma cottoni seaweed contains antioxidants that can neutralize the oxidative properties caused by NaNO2. The purpose of this study is know the effect of Eucheuma Cottoni seewead extract on Malondialdehid Level and Spermatozoa of White Rat (Rattus Norvegicus L.) that induced by NaNO2. The design used was a completely randomized design (CRD) consisting of negatif control treatment (K-), positive control treatment (+), dose treatment 1 (P1), dose treatment 2 (P2) and dose treatment 3 (P3). The negative control treatment (K-) was given distilled water while the positive control treatment was given sodium nitrite at a dose of 22.5 mg / kg BW. Treatment doses 1,2 and 3 were given a combination method of sodium nitrite and seaweed extract at a dose of 150 mg / kgBB / day (P1), 300 mg / kgBB / day (P2), and 450 mg / kgBB / day (P3). Observations were made by observing the levels of MDA (Malondialdehyde) in serum and sperm quality namely integrity of the membrane, viability, motility and morphology of spermatozoa male white rats. Data analysis was carried out through the One Way Anova statistical test and continued with the Duncan test. The results showed that seaweed extract dose of 150 mg/kgBW significantly could decrease MDA (Malondialdehyde) levels, increased viability, motility integrity of the membrane and morphology of spermatozoa.

Abstract

The study of flowering and fruiting periods of Sauromatum horsfieldii Miq. (Araceae) in its natural habitat is the first aroid’s observation on flowering biology which conducted in Bali. This early study aimed to investigate the flowering and fruiting behavior of S. horsfieldii in the natural habitat inside Bali Botanic Garden. The result showed that it took roughly more than 16 days for flowering period, while fruiting time duration completed around 60 days or 2 months. Flowers maturity (anthesis) occured approximately 72 hours or 3 days for a cycle of the flowering time. Female flowers reached anthesis prior to male flowers. Insects were supposed as pollinator which played a significant role to reproduction success. The observation was terminated due to the study’s objects were missing at the same time when the ripening berries had already finished observing. Wild long-tailed macaques and/or wood mice were most likely to be the suspects.

Abstract

One of the diseases that become a health problem because of the increasing prevalence every year is hypertension. The high of ROS (Reactive Oxygen Species) in the body will increase the formation of excess free radicals and make the endogenous antioxidant SOD (Superoxide dismutase) be used in excess so that it becomes the cause of the emergence of hypertension. Herbal tea parasite and mango parasite are plants that have the potential to prevent hypertension by increasing SOD activity in the body. The purpose of this study was to determine the effect of exposure to a combination of methanolic extract of tea parasite and mango parasite (CMETMMM) on increasing serum SOD levels in DOCA-salt-induced hypertension rats using a preventive model. In this study, experimental methods were used with 25 male Wistar rats as test animals which were divided into 5 groups and there were 5 rats in each group, namely negative control (K-), positive control (K+), and group with CMETMMM exposure treatment (P1) at a dose of 50 mg/kgBW, (P2) at a dose 100 mg/kgBW, and (P3) at a dose 200 mg/kgBW. The results showed that CMETMMM exposure had an effect on increasing serum SOD activity in hypertensive rats with a significant difference in the mean value between all groups with p-value <0,05. The effectiveness of exposure to tea parasite and mango parasite was controlled by CMETMMM at a dose of 100 mg/KgBW which is an effective dose in increasing SOD serum levels of rats with DOCA-Salt hypertension model.

Abstract

Pesticides play an important role in killing pests, both insects, fungi and weeds. The use of active-based pesticides in the environment can lead to the possibility of pollution. The use of carbofuran can cause pollution to soil, water, air, and also wildlife. Bioremediation is the right solution to overcome the problem of environmental pollution due to the use of pesticides. Bioremediation can be done by utilizing Indonesian indigenous bacterial isolates. This study aims to obtain information on the optimal growth of carbofuran-resistant bacterial isolates, the effect of adding various concentrations of carbofuran on the growth of bacterial isolates, and their ability to degrade carbofuran. Indigenous bacteria studied were isolates of carbofuran resistant bacteria from the Environmental Technology Center (PTL) collection. Bacterial growth was measured using a 600 nm wavelength spectrophotometer. The concentrations of carbofuran used were 100, 500, and 1000 ppm. Carbofuran degradation ability was measured using High Performance Liquid Chromatography (HPLC). The results showed that the addition of various concentrations of carbofuran affected the growth of bacterial isolates by reducing cell density. The growth of isolates R2, BN5.2 and BN5.3 was best in a medium containing 500 ppm carbofuran, while the growth of isolates R1, R3.2, R3.3, BN2.3, BN5.1 and C was best in a medium containing 1000 ppm. Bacterial isolates R2 and R3.3 were able to degrade carbofuran by 68.47% and 66.68%, respectively, for 3 days.

Abstract

Kombucha tea has antibacterial activities against Gram-negative, Gram-positive bacteria, and antibiotic resistant bacteria. Methicillin-resistant Staphylococcus aureus (MRSA) is a strain of Staphylococcus aureus bacteria that has resistance to antibiotics. MRSA is the main cause of nosocomial infections and various clinical syndromes. This study aimed to determine the antibacterial of kombucha tea and the difference in antibacterial effect between kombucha green tea and kombucha black tea in inhibiting MRSA. Kombucha green tea and kombucha black tea were made by fermenting liquid. The kombucha tea antibacterial test on MRSA was determined using well diffusion method. The antibacterial differences between kombucha black tea and kombucha green tea were analyzed by using t-test. Kombucha green tea has a higher total acid content with a lower pH than black kombucha tea. Kombucha black tea and kombucha green tea antibacterial activities on MRSA were shown by an irradiance zone, with a diameter of 14 ± 0,85 mm and 17 ± 0,93 mm. Irradical zone shows that the activities of kombucha black tea and kombucha green tea is categorized as weak. Therefore, kombucha tea has not been effective as an antibacterial against MRSA. The results of t-test showed that there were differences in antibacterial activities between kombucha green tea and kombucha black tea against Methicillin-resistant Staphylococcus aureus (MRSA).

Abstract

Carbon tetrachloride (CCl4) is a chemical compound that is toxic, but is still often used in the refrigeration industry, fire extinguisher, and pesticide. Continuous use of CCl4 can trigger the formation of free radicals, potentially damaging the liver and kidneys. Soursop (Annona muricata L.) is a plant that can be used as an alternative medicine because it contains antioxidant compounds that can prevent free radical formation. This study aims to determine the effect of soursop leaf extract on the histopathology of mice (Mus musculus L.) liver and kidneys induced by carbon tetrachloride. This research used a completely randomized design with 24 male mice, which were divided into 4 treatments consisting of negative control (K-) was given 0.5% Na-CMC solution, positive control (K+) induced by CCl4 0,007 mL/20g BW which was dissolved in 0,1 mL coconut oil, and two treatments induced CCl4 0,007 mL/20g BW and given soursop leaf extract at a dose of 100 mg/kg BW (P1) and 200 mg/kg BW (P2). Parameters observed in liver histology were fatty degeneration, hydropic degeneration, necrosis, congestion, and inflammatory cell infiltration. Parameters observed in kidney histology were fatty degeneration, necrosis, inflammatory cell infiltration, and glomerular swelling. The results showed that there was significantly different decrease in damage (p<0,05) in P1 and P2 compared to the positive control (K+) in liver and kidney histology incisions, it can be concluded that soursop leaf extract was able to repair liver and kidney damage after induced by carbon tetrachloride.
