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 high use of insecticides can cause soil contamination in the rice field environment, so a solution is needed to reduce the contamination and the negative impact on human health. One of the efforts that can be done to overcome this problem was by bioremediation. The bioremediation technique was chosen due to it is eco- friendly, efficient, and cost-effective in its application. However, bioremediation relies on the capacity of living organisms to absorb, accumulate, translocate and detoxify pollutants in a polluted environment. The objective of this study is to explore microbes that can be used as bioremediation agents in soil exposed to various types of insecticide contamination. The results of this study was as many as ±56 species of microbes can be used as bioremediation agents for various types of insecticides so that bioremediation needs to be carried out in order to avoid pesticide residues on soil and agricultural products.

Abstract

Actinomycetes are a group of filamentous bacteria with high biosynthetic potential that can produce secondary metabolites. Actinomycetes are known to produce secondary metabolites which are potential as antimicrobial, antitumor, and others. Actinomycetes can be found abundantly in diverse environments, including environments with extremely high temperatures such as hot springs, deserts, geothermal areas, and hydrothermal vents. They can survive in high temperatures due to their membrane lipids containing straight-chains and more saturated fatty acids that protect the membrane's fluidity to maintain membrane function. Thermophilic actinomycetes are potential producers of thermostable enzymes and bioactive compounds, which are important in the pharmaceutical, health, and industrial fields. Thermophilic actinomycetes are still less explored for novel metabolites and antimicrobial compounds due to the difficulty in isolation, maintenance, and preservation in pure culture. Novel bioactive compounds produced by actinomycetes are conventionally discovered by isolating potential strains and screening the compound bioactivity through various bioassays. A sequence-independent approach, termed the OSMAC (one strain many compounds), has been widely used in natural product research for activating cryptic biosynthetic gene clusters (BGCs) by modifying the growth conditions of a bacterial culture. This approach aims to optimize the number of secondary metabolites produced by one single microorganism. The application of the OSMAC method has been proven successful in revealing the biosynthetic potential of bacteria.

Abstract

This study was conducted to determine the benefits of aromatherapy for anosmia people after exposure to COVID-19. Aromatherapy was often used for health therapy so it has the potential for the treatment of anosmia. This study is necessary to be done because there are a lot of anosmia sufferers and there is no effective way to treat it. The study of post-COVID-19 anosmia continues to evolve and more needs to be researched. This study was conducted by reviewing several literature studies originating from international and national journals, theses, and dissertations with a year limit of the last 10 years. From some literature it is known that aromatherapy can reduce the risk caused by anosmia. Aromatherapy can enter through the body's circulatory system and olfactory system through fragrances, It will affect the condition, memory, and psyche of a person. Although not very effective, further research on the benefits of aromatherapy for people with anosmia is necessary.

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 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.

Abstract

According to data from the Food and Drug Supervisory Agency (BPOM), throughout 2012, the incidence of poisoning due to consuming food occupied the highest position, at 66.7%. One of the causes of food poisoning is the presence of food additives such as formalin, borax. At Muhammadiyah Elementary Schools 1, 2 and 3, there are a lot of street food vendors, such as; fried noodles, meatballs, sausages, snacks. This research aims to find out which snacks contain borax and formalin and to find out which snacks are safe and unsafe for children. Sampling used a simple random technique with the assumption that a lot of samples were purchased by children and were thought to contain borax and formalin, so that a sample of 15 snacks were obtained from 6 snack sellers. Then given code seller 1 until 15. In this research, the borax and formalin tests were carried out qualitatively, using test kit. The results of the research show that of the 15 samples of snacks that have been tested, there are no samples that are positive for borax and formalin. It is proven by the absence of color changes that occur in the samples of snacks that have been tested.
