Abstract

Aspartame is an artificial sweetener in foods and beverages. Continuous use of aspartame will result in oxidative stress in the liver. So we need antioxidants from outside the body such as periwinkle leaves.This study aims to determine the effect of periwinkle leaves (Catharanthus roseus L) on aspartame-induced liver histology. This study used 24 male mice divided into 4 groups, namely negative control (K-) without treatment; Positive control (K +) treatment of aspartame; D1: treatment of aspartame and periwinkle extract doses of 0.42 mg/kg. D2: aspartame and periwinkle  extract doses of 0.84 mg/kgbb. Administration of aspartame dose of 0.2 mg /kgbb by intraperitoneal  for 14 days followed by gavage administration of periwinkle leaf extract for 12 days. The liver was taken on the 27th day by surgery, then made slide histology with Hematoxylin-Eosin staining. The results show that the administration of Catharanthus roseus leaf extract at a dose of 0.84 mg/kgbw in aspartame-induced mice was effective in reducing hepatocyte damage, namely hydrophilic degeneration and necrosis.

Abstract

The ecological impacts of tin mining activities in the Bangka island is the presence of heavy metal contamination that accumulated in the environment. One of the heavy metals that was often found in post-tin mining areas is lead (Pb). Mycoremediation is a method that can be used to reduce lead pollution in post-tin mining areas. This study aimedto isolate, resistance test and identify to Pb-resistant soil fungi (rhizosphere) in the post-tin area of Bangka. The research methods included isolation, test of fungal resistance to Pb metal (Control, 150ppm, 250ppm, 350ppm, 500ppm, 1,000ppm, 5,000ppm and 10,000ppm), macroscopic and microscopic identification. The results showed that 9 isolates tested, there were 6 isolates that were resistant to Pb up to the concentration of 5,000 ppm, namely isolates I1(Rhizoctonia), I2(Penicilllium sp1), I5(Papulaspora), I6(Penicillium sp2), I7(Penicillium sp3) and I9 (Sclerotium). Three isolates of soil fungus were not resistant to Pb up to a concentration of 5,000 ppm, namely isolates I4 (Sclerotium), I8(Microsporum), and I10(Cladosporium). All isolates did not grow anymore at a concentration of 10,000 ppm of Pb.

Abstract

The car wash wastewater has a proportion of detergent  and it can cause considerable impacts to pollute the environment and health if they are not processed in well. SSVF CW is one of  an alternative wastewater treatment, because it has the advantage such as wastewater flowing below the surface of the media so it  reduces the smell of wastewater. The objective of this study was to determine the  removal efficiency of reducing pollutants in the wastewater of treated car wash by Constructed Wetland and the influence of Chrysopogon zizanioides rhizosphere depth in supplying DO distribution. This experimental laboratory scale study used 2 PVC for reactor. Each pipe has 4 sampling points. The DO was measured from different depth, while the other parameters were from the effluent. The ratio of the media used was  1:3:2:4 from the top to the bottom. The SSVF CW system had high TSS removal efficiency of 94.74%, while the removal efficiency of COD, Detergent, and Phosphate was76.21%, 54.54%, 30.65%, respectively. DO distribution at a depth of 84 cm in both pipes increased even though the root zone was only 26.5 cm.

Abstract

Tamarind (Tamarindus indica) is a versatile plant, findable in Indonesia (Java, Bali, North Sumatra, West Kalimantan, and South Sulawesi). The leaves are green to brown, round, 1-2.5 cm long and 4-8 mm wide, rounded tips, rounded base of blades, and flat edges. The content contained in tamarind leaves such as flavonoids, tannins, saponins, and alkaloids is believed to inhibit Propionibacterium acnes activity. This study aims to determine the effect of tamarind leaf extract ointment in controlling the growth of the bacteria Propionibacterium acnes that triggers acne. This study applied a Completely Randomized Design with 96% ethanol maceration method. Propionibacterium acnes was evidenced by the inhibition zone formed. The diameter of the inhibition zone of the 25% ointment was 1.235 cm, the 30% concentration was 1.385 cm, the 35% concentration was 1,680 cm, and the ointment base was 0 cm. The ANOVA test showed a significant value of 0.000<0.05, so there was a significant difference between the inhibition zone and the 95% confidence level. The results of Post Hoc test were P<0.05, meaning that there was a significant difference between the bases with formulas 1, 2, and 3. Thus, tamarind leaf extract ointment had a strong inhibitory effect on Propionibacterium acnes.

Abstract

Staphylococcus aureus bacteria are resistant to several kinds of antibiotics, so there is a need for natural antibiotics derived from plants, namely aloe vera. The objective of this study was to determine the effect of aloe vera leaf extract in inhibiting the growth of Staphylococcus aureus bacteria. The type of research used was experimental using the disc diffusion method with a total of 25 samples with five concentrations of 20%, 40%, 60%, 80% and 100% then the data were analyzed using the One Way ANOVA test. The result is that aloe vera extract can inhibit the growth of Staphylococcus aureus bacteria, it is proven by the presence of a disc zone at 100% concentration with a diameter of 11.5 mm. The results of statistical analysis with the One Way ANOVA test, in a value of 0.000, meaning that there was a significant difference. The conclusion obtained is that aloe vera extract can slow down the growth of Staphylococcus aureus bacteria but based on the standard value of sensitivity of an aloe vera extract bacteria with the highest concentration it cannot be used as an antibiotic because it is less than the standard value of 14 mm.

Abstract

Antihypertensive therapy used in patients with End-Stage Renal Disease undergoing hemodialysis is objected to decrease mortality related to ESRD complications. Nonadherence to antihypertensive therapy can lead to uncontrolled blood pressure. This study aims to determine the level of adherence to antihypertensive drugs and its correlation to blood pressure control in ESRD patients undergoing hemodialysis. It was an observational analytic study based on the cross-sectional method. Sixty  person subjects were involved using the quota sampling technique. The level of adherence was examined using the Modified Morisky Scale questionnaire. Blood pressure data were obtained from mean values of respectively pre, during, and post-hemodialysis blood pressure within four hemodialysis visitations. The data was examined bivariately using the Chi-square test with a 95% confidence interval. The results show most patients have high level of adherence to antihypertensive treatments (55%) yet have uncontrolled levels of blood pressure (95%). The Chi-square analysis found there is no significant relationship between the level of adherence to antihypertensive therapy and the average blood pressure level of ESRD patients who undergo hemodialysis (p-value 0,301). This finding suggests a consideration in monitoring the effectivity of hypertension management that adherence is not a single significant factor affecting the successfulness of medication.
