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

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

Patients who self-quarantine were carried out to break the chain from the spread of the COVID-19 virus, but a new problem arose: solid medical B3 waste originating from these patients. If this B3 medical waste is not managed properly, it can potentially transmit and be contaminated by infectious substances. Management of infectious waste from self-quarantine patients was minimal because most people did not know about it, and there was a lack of infrastructure from the government. Therefore the researchers were interested in researching the management of B3 waste, substantial B3 waste, from people who carried out Covid-19 self-quarantine. This study aimed to determine the community's effectiveness in managing solid medical B3 waste from COVID-19 self-quarantine activities. Using the snowball sampling method and cross-sectional design, the results showed that there was a significant relationship between Attitude (P Value = 0.000), Knowledge (P value = 0.006), Age (P Value = 0.019), Gender (P value = 0.000), Occupation (P value = 0.000) and Education (P value = 0.04) on community behavior in managing B3 medical waste during the Covid-19 self-quarantine period. Management of Solid B3 Medical Waste from self-quarantine has not been effective since its application is still low, and local drop boxes were not available as temporary shelters for B3 waste.

Abstract

The kidneys are the most important to excretory organs because they have function to remove waste products from the body has metabolism. In the excretory system, the damage that could occur is the kidney has decreased until finally unable to perform its function properly which is called Chronic Kidney Disease (CKD). Chronic Kidney Disease caused by age, gender, and a history of diseases such as diabetes. One of the nanoparticle therapies that could be given to patients with chronic kidney disease is Micro-Chinese Medicine Osmotherapy. The purpose of this paper is to determine: 1) structure and how they work of the kidney and its relation to the urinary system, 2) causes and effects of chronic kidney disease on the urinary system, 3) mechanism of the urinary system in conditions of chronic kidney disease, and 4) mechanism and results of Micro-Chinese Medicine Osmotherapy. The research method used is a literature review from various sources which helps in reviewing the four focus of the study. Kidney is divided into three major parts, namely cortex, medulla, and renal pelvis. The excretory system has three stages, including filtration, reabsorption, and augmentation. Chronic kidney disease can be caused by age, where older age has a risk of developing CKD. Kidney disease can be divided into several stages, including normal, at risk of damage, kidneys are damaged, kidneys are not functioning properly and kidneys are no longer functioning or chronic kidney disease (CKD). The mechanism of action of Micro-Chinese Medicine Osmotherapy is divided based on its function, named as anti-inflammatory, anti-coagulation, and degradation. The results of treatment for kidney disease is Micro Medicine Osmotherapy could make all renal arteries of patients with chronic kidney disease widen and increase perfusion.

Abstract

The domestic wastewater is mostly produced in settlement areas and usually directly discharged into the environment. Its high organic matter and nutrients will pollute the environment. As an alternative, one of the good wastewater treatment systems is the Sub Surface Flow Constructed Wetland. This system has some advantages such as easy implementation, low cost, and doesn’t need a large area. The aim of this study is to determine the efficiency of Canna indica and Cyperus alternifolius to reduce organic matter and phosphate. This study is an experimental study with two treatments (T1: SSF CW with Canna indica; T2: SSF CW with Cyperus alternifolius). The SSF CW system contains gravels those diameters are 3-5 cm, 1-3 cm, and <1 cm, as well as paddy soil as media with HRT of 3 days. The parameters measured included temperature, BOD, DO, PO4, and pH. Based on this study, it can be concluded that the higher removal efficiency of organic matter is shown by the CW SSF system with Cyperus alternifolius. It is 48,86% in T2 and 42,69% in T1. While the removal efficiency of phosphate in T1 and T2 are 65,70% and 67,21% respectively.
