Abstract

The use of recycled frying oil or deep frying oil (DFO) lead to increase in free fatty acid, trans fatty acid and free radical compound. It can cause non-alcoholic fatty liver disease (NAFLD). a chronic liver disease cause the risk for cirrhosis and heart cancer. However, there is no medicine for preventing the disease. The present study was conducted to investigate the turmeric reduces steatosis hepatocyte of male Wistar rat NAFLD model. The study used experimental randomize post-test only control group design. The 24 samples consist of four treatment groups. Group I (control): normal diet + DFO (10 μl/g/day on 6 times heating), Group II, III and IV: normal diet + DFO (10 μl/g/day on 6 times heating)+ turmeric Extract (100, 200, and 400 mg/kg/day) by given for 30 days through oral induction. The results of Kruskal-Wallis test showed a significant difference between the four treatment groups (P= 0.019) .The results of Mann-Whitney test showed significant difference in steatosis hepatocyte between the control group (P1) and treatment group(P3) the dose of 200 mg/kg BW. This suggests that a dose of 200 mg/kg BW is an effective dose in decreasing hepatocyte steatosis.

Abstract

The levels of Pb, Cu, Cd and Zn in sawi (Barsssica rapa), ground kuna (Ipomea reptans), and spinach (Amaranthus tricolor) in the area of Paya Rumput Titipapan Medan village have been done. The goal is to know the levels of these metals in vegetables grown in the agricultural area of Paya Rumput Titipapan Village. Samples taken randomly in wash drained and weighed. Wet weight then dried at a temperature of 50-100o C for 3 hours, After dry on weigh in gerus until smooth. The sample was destructed with concentrated nitric acid with temperature 80o C, the sample was analyzed by using atomic absorption spectrophotometric (AAS). The results showed the highest levels of lead found in spinach is 6 mg / kg. Levels of cadmium in kale and spinach is 3 mg / kg. While the Cu content on the analysis results are still within the maximum limit. The concentration of Pb, Cd, Zn in each sample exceeds the maximum allowed by the Decree of Dit Jend POM No 03725 / B / SKVII / 89 and SNI 7387: 2009.

Abstract

This reseach aims to determine the composition of secondary metabolites of kirinyuh leaf extract (Euphatorium ordoratum.L) and antimicrobial properties of the extract against Staphylococcus aureus and Escherichia coli. The study was conducted in three phases: the first phase is manufacture kirinyuh leaf extract (Euphatprium odoratum L) through maceration method using N-Hexane solvent and methanol. In stage II, phytochemical screening, namely the identification of secondary metabolites (alkaloids, flavonoids, terpenoids and steroids) to the crude extract of  leaves kirinyuh (Ephatorium odoratum L) in the form of antimicrobial properties of extracts against Staphylococcus aureus and with variations extract concentrations of 0%, 1 %, 5%, 10%, 15%, 20%, and 25% Echerichia coli and incubated at 37°C for 24 hours. The research found that such compounds secondary metbolit alkaloids, flavonoids, steronoid, and saponin, which dominates the secondary metabolites of four that alkaloid. While the screening test of phytochemical N-hexane extracts is not contain metbolit secondary compounds, testing against bacteria possess bioktivitas inhibition at concentrations of 15% with inhibition zone of 1.3 cm on Escherichia coli bacteria and 1.0 cm in bacteria Staphylococcus aureas. This shows kirinyuh leaf extracts have the ability as an anti-microbial.

Abstract

Research the effect of andaliman leaf extract on mice ovaries, volume test material using oral gavage needles as much 0.1 ml / 10 g bb 4 days before and after estrus stage and using RAL non-factorial method consisting of control and treatment group. Treatment consisted of factor test material with dose 2500, 5000, 10000, 20000, 40000 ppm. Chemical content of andaliman leaf extract shown from results study are alkaloids, steroids and saponins. Giving treatment of andaliman leaf extract for 9 days on histological data in the number primary, secondary, De Graff, and atretic follicles experienced fluctuating changes, but statistically did not show a significant difference between treatment and control mice groups, while different results were significantly shown in the number of corpus luteum. Parameters diameter of primary follicles, De Graff, and corpus luteum tended to experience changes that fluctuated, but statistically did not show the difference between the treatment and control mice groups, while the diameter of secondary and atretic follicles showed significantly different results. From the results study, administration of andaliman leaf extract affects histological mice ovaries, because it affects oogenesis and ovulation, but fluctuates, possibly due to crude extract, which has not isolated chemical content.

Abstract

Shallot variety of Bima Brebes is a shallot variety that is widely cultivated by farmers in Indonesia because it is easy to grow and adapt to the local environment. However, in reality many farmers use the previous harvest for the next planting seed so that the yields obtained will be of poor quality. This study aims to determine the effect of giving nitrogen through corona incandescent plasma discharge and goat fertilizer on the growth of shallots so that it can improve the quality of onion seedlings. This study used a Completely Randomized Design (CRD) with a factorial pattern using a corona incandescent plasma discharge factor and goat manure. The results showed an interaction between the two factors that can be seen from the plant height parameters which showed significant results in the treatment of plant seeds that were plasma radiation for 30 minutes and the planting media were given goat manure 65 g. Based on the results of the study it can be concluded that the administration of corona incandescent plasma discharge and goat manure on the cultivation of shallots varieties of Bima Brebes was able to accelerate the time of sprouting by 200.3% and increase the growth of onion plants.

Abstract

One alternative to waste processing polystyrene is to use Tenebrio molitor larvae. This study aims to determine the increase in body length and weight, rate of degradation, and value of Waste Reduction Index (WRI) of larvae T. molitor. This study used laboratory experimental using completely randomized design experimental design model (CRD) data analysis with control and 4 feed treatments. Each treatment level was repeated 5 times in order to obtain 25 experimental units. Larvae were reared in a plastic container containing 10 larvae. Each larvae were given bran feed for control and polystrene for treatment, each feed as much as 1 gram. The polystyrene used were food packaging, walls, electronic packaging, and ice boxes. Larvae were measured for length and body weight every 3 days for 30 days. Parameters observed were increase in length and weight of larvae, rate of degradation and WRI values.The highest mean value of increase in larval length on the polystrene wall was 1.69 cm. The lowest value was polystyrene food packaging (1.59 cm). The average weight gain of larvae has a uniform value in the control and treatment of 0.07 gr. The highest degradation rate and WRI values were polystyrene wall and electronic packaging at 0.019 and 0.63%. while the lowest values were polystyrene food packaging at 0.11 and 0.37%.
