Pemanfaatan tanaman obat untuk melawan COVID-19 menjadi tren di masyarakat beberapa tahun terakhir. informasi mengenai penggunaan tanaman obat untuk melawan COVID-19 menyebar dengan cepat sehingga dikhawatirkan dapat meningkatkan kesalahan informasi dan dapat menimbulkan permasalahan kesehatan baru akibat penggunaan obat tradisional yang kurang tepat. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pemahaman masyarakat terkait pemanfaatan obat tradisional serta cara pembuatannya yang baik untuk melawan COVID-19. Kegiatan ini dilakukan dalam bentuk ceramah secara daring yang melibatkan 47 orang guru dan pengelola Lembaga Pendidikan Lukman Al Hakim Hidayatullah, Surabaya. Penilaian terhadap tingkat pengetahuan para peserta dilakukan melalui pre-test dan post-test menggunakan instrumen berupa sepuluh pertanyaan pilihan ganda dalam format respons tunggal tentang obat tradisional untuk melawan COVID-19 dan cara pembuatan obat tradisional yang baik. Diperoleh peningkatan nilai rata-rata post-test (75,83) dibanding pre-test (51,39) yang menunjukkan bahwa adanya peningkatan pengetahuan para peserta webinar tentang obat tradisional untuk melawan COVID-19 beserta cara pembuatannya yang baik.

Infectious disease is a disease caused by microbes, including bacteria. One of the microorganisms that often causes infectious disease is Streptococcus pneumoniae and Klabsiella pneumoniae. Based on empirical data, plant that has antimicrobial potential is amethyst leaves (Datura metel L.). This study aims to know the antibacterial activity and concertration of amethyst leaves (Datura metel L.) against Streptococcus pneumoniae and Klabsiella pneumonia. This is an experimental study which includes antibacterial activity test, MIC (Minimum Inhibitor Concertration) test, MFC (Minimum Fungicidal Concertration) test, and bacterial potency test. The finding shows that the antibacterial activity test of amethyst leaves (Datura metel L.) methanol extract is able to inhibit bacterial growth of Streptococcus pneumonia at a minimum inhibitor concertration of 15% and an optimum concertration of 50% with an average of 16.33 mm and 19.30 mm. Meanwhile, for Klabsiella pneumoniae, the minimum inhibitor concertration is 20% and the optimum concertration is 50%, with an average of 13.82 mm and 17.73 mm. this is based on the results of One Way Anova data (a 0.01) with a 99% confidance level.

Christ's torn jujube (Ziziphus spina-christi L.) is a medicinal plant that has many benefits for curing or treating diarrhea, fever, and cancer. One of the compounds that play role is an alkaloid. This study was generated to identify the alkaloid compounds in the leaves of the Christ’s jujube torn using the UV-Vis spectrophotometry method. Christ's torn jujube leaves were macerated using 3 types of solvents with different polarity levels i.e., n-hexane, ethyl acetate, and methanol. Furthermore, phytochemical screening of alkaloid compounds was carried out. A Christ jujube leaf sample that was positive for alkaloids was found in the ethyl acetate extract; then identified using thin layer chromatography with eluent n-hexane: ethyl acetate (8:2), yielding 4 points with an Rf value of 0.25; 0.4 ; 0.52 ; and 0.62. Furthermore, phytochemical screening of alkaloid compounds was carried out. Christ' torn jujube which were positive for alkaloids present in the ethyl acetate extract were identified using thin layer chromatography with n-hexane eluent: ethyl acetate (8:2), yielding four spots with an Rf value of 0.25; 0.4 ; 0.52 ; and 0.62. The four spots were identified using UV-Vis spectrophotometry, obtained a wavelength of 248 ; 268 ; 268 ; and 255. Based on the identification results on the leaf extract, each stain was suspected to contain cantin-6-one alkaloid compounds.

Garlic (Allium sativum L.) is one of tuber vegetable crops that is widely grown in various countries in the word and is often used as food spices and medicines. The purpose of this study was to characterize the volatile oil compound ethyl acetate extract of garlic (Allium sativum L.) using Uv-Vis and IR spectrophotometric metods. Several methods used in this research included extraction, identification of compounds, fractionation, thin layer chromatography, prepative thin layer chromatography, and characterization of compounds using Uv-Vis spectrophotometry and IR spectrophotometry. A total of 3000 grams od garlic was macerated using 70% ethanol, then evaporated and obtained a thick extract of 421.5 grams. The results of thin layer chromatography used an eluent ratio of Methanol : Ethyl Acetate (4:2) obtained stains with an Rf value of 0,55. The optimizion result of maximum wavelength of garlic isolated (Allium sativum L.) is 232 nm wich indicated the presence of an electron transition n→σ*.The results of IR spectrophotometry had fuctional groups at wave numbers 3231.530 cm-1 (N-H), 1637.48 cm-1 (C=O), 1014.65 cm-1(C-N).

Traditional medicines are ingredients in the form of plant ingredients, animal ingredients, mineral substances, galenic, or mixtures of these ingredients that have been used for treatment from generation to generation and can be applied in accordance with the prevailing norms in society. One type of traditional medicine that is currently consumed by many people is herbal medicine. Jamu (empirical based herbal medicine) is a traditional medicine that is provided traditionally which contains all the plant ingredients that make up the herbal medicine which is hygienic (free of contamination) and is used traditionally. The research objective was to determine the presence of the chemical ingredient of dexamethasone drug in jamu for rheumatic and also to quantitatively determine the dexamethasone level in jamu for rheumatic by using uv-vis spectrophotometry. The results showed that all five jamu for rheumatic samples contained the chemical ingredient of dexamethasone drug with levels of each sample, namely jamu A 99,83 mg, jamu B 34,71 mg, jamu C 363,13 mg, jamu D 9,979 mg, and jamu E 778,97 mg
