Coronavirus Disease (COVID-19) is an infectious disease that has a high fatality rate and is spreading quickly throughout the world. The WHO claims that SARS-CoV-2, a brand-new coronavirus strain, is to blame for this outbreak (Severe Acute Respiratory Syndrome Corona Virus-2) and that COVID-19 must be treated with both conventional medical therapy and a combination of modern medicine. The technique of this study, a review of the literature, focused on numerous investigations looking at the potential of curcumin molecules from turmeric to cure the COVID-19 disease. Primary data for scientific papers is gathered from national and international journals through searches on electronic search engines like Google Scholar, Sciencedirect, or PubMed and selected publications are assessed, evaluated, and interpreted by authors. Turmeric contains substances that are immune system boosters, anti-inflammatory, antitumor, antiviral, and antioxidants. Curcumin may prevent a number of viral infections, according to evidence. In vitro testing has shown that the SARS-CoV virus is resistant to curcumin's antiviral properties. It's possible that curcumin can halt viral replication. Curcumin has the potential to treat COVID-19 effectively. Curcumin has antiviral activity that can fight the SARS-CoV-two virus. Treatment with curcumin can change the virus top protein structure, preventing the virus from entering the body and from budding. Future study on the use of curcumin as SARS-Cov-2 virus inhibitory agent is necessary in order to employ it as a novel and long-lasting therapy option for COVID-19 patients.

The quality of the water used by the community in Worongnge Village is poor water quality, therefore alternative solutions are needed to treat water so that the water is suitable for use. One process that can be used is the coagulation-flocculation process with Moringa seeds. The purpose of this study was to determine the concentration of Moringa seeds can stabilize the quality of water pH, TDS, and turbidity (turbidity) of river water in Worongnge Village. This research was conducted in the form of an experiment consisting of 5 treatments and each treatment used 1 liter of river water and each would be given 3 variations of time: (12 hours, 24 hours, 36 hours). The design is as follows: P0: 1 liter of river water without treatment P1: Provision of 1 liter of river water and 2 g of Moringa seed extract. P2: Giving 1 liter of river water and 4 grams of Moringa seed extract. P3: Giving 1 liter of river water and 6 grams of Moringa seed extract. P4: Giving 1 liter of river water and 8 grams of Moringa seed extract. The results of the research carried out found that the effective concentration of Moringa seed extract was 2gr(P1) where the results were water pH 7.2, water TDS 0.191, and turbidity (turbidity) 46. The use of Moringa oleifera seed extract as a natural coagulant is effective in reducing the turbidity of river water.

This study aims to determine the mother-in-law's tongue (Sansevieria trifasciata) has the potential to remediate Cu contained in the soil. The method used is an experimental method to test the absorption potential of mother-in-law's tongue plant on ground contaminated with Cu metal. The results showed that the samples from days 0, 3, 6, and 9 did not show any changes in the adsorbed metal. The four samples contained the same heavy metal copper (Cu) concentration, which was <0.50 ppm. In conclusion, the mother-in-law's tongue (Sansevieria trifasciata) is not very effective as phytoremediation of soil contaminated with Cu metal but can still be used as phytoremediation.

This study aims to determine the initial content of copper metal found in land kangkung (Ipomoea reptans) plants. The method used is the descriptive quantitative analysis method. The results showed that samples 1, 2, 3, and 4 each had <0.50 mg/kg copper metal found in land kangkung. In conclusion, land kangkung has not been polluted, so it is safe for consumption and can also be used as phytoremediation in an environment contaminated by heavy metals. Keywords: Detection, Kangkung Land (Ipomoea reptans), Copper Metal (Cu)

This study aimed to obtain a Puring cultivar (Codiaeum variegatum) that can adapt to heavy and robust copper (Cu) stress and test its potential as a phytoremediation plant. The method used was a randomized block design (RAK). The results showed that the number of leaves and plant height did not show a significant difference. The most important copper (Cu) convergence in the formation was found in the Teri cultivar, with a convergence level of 126,399 ppm. In conclusion, puring cultivar can be used as a phytoremediation agent in an environment contaminated with substantial copper (Cu) metal because of its long roots and does not require more expensive costs.
