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

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.

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

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.
