“…The bacteria were cultured in a nutrient broth for 24 hours at 37°C before testing. The turbidity of the tested bacteria was measured using the 0.5 McFarland standard (Situmeang et al 2019). Two hundred microliters of bacterial suspensions were applied spread onto the MHA.…”

Abstract. Walean M, Melpin R, Rondonuwu M, Pinontoan KF, Maliangkay HP, Astriani M. 2020. Phytochemical screening and biological activities of pakoba (Syzygium luzonense) stem bark ethanol extract. Biodiversitas 21: 2377-2382. Pakoba (Syzygium luzonense (Merr.) Merr) as an endemic and ethnomedical plant of North Sulawesi was investigated for its phytochemical constituents and biological activities. The presence of phytochemicals constituents, antibacterial, antioxidant activities, and antihyperglycemic of pakoba stem bark ethanolic extract (PSBEE) were also investigated. Pakoba stem bark was extracted using ethanol. The extracts were evaluated for antimicrobial activity using the Kirby Bauer method, whereas antioxidant activity was determined by using 1,1-diphenyl-2-picrylhydrazyl radical scavenging assay. Alloxan-induced diabetic rats investigation was used to determine the antihyperglycemic activity. The phytochemical analysis revealed that tannins, alkaloids, and flavonoids were present in PSBEE. PSBEE has potent antioxidant activity with antioxidant activity index = 1.02. PSBEE significantly reduced the blood sugar of hyperglycemic rats with an optimum dose of 300 mg/kgbw. In this study, PSBEE has weak antibacterial activity against in Escherichia coli and Staphylococcus aureus.

“…The resulting inhibition zone is wider. The antibacterial potential of Simargaolgaol extract was seen to be stronger at higher concentrations as well as research (Simorangkir et al 2019;Situmeang et al 2019;Juwitaningsih et al 2021) which stated that the higher the concentration of the extract, the wider the diameter of the inhibition zone formed.…”

The Simargaolgaol (Aglaonema modestum Schott ex Engl) plant is a plant that grows wild in Barus District, Central Tapanuli, North Sumatra which is used by the community as a medicinal plant. This study aims to determine the antibacterial activity of n-hexane, ethyl acetate and ethanol extracts from Simargaolgaol leaves against Escherichia coli and Salmonella typhi bacteria. The antibacterial activity test of Simargaolgaol leaves was carried out using the disc diffusion method. The results of antibacterial activity showed that the highest inhibitory power of Simargaolgaol leaf extract was ethanol extract (polar), ethyl acetate extract (semi polar) and n-hexane extract (non polar). The inhibitory power of ethanol extract, ethyl acetate, and n-hexane against Escherichia coli bacteria was 13.1 mm (strong); 9.7 mm (medium); 8.0 mm (medium) and for Salmonella typhi bacteria respectively 11.2 mm (strong); 10.7 mm (strong) and 9.3 mm (medium). With the concentration of the extract in the diameter is 10%. Based on this, it can be concluded that Simargaolgaol leaf extract has potential as an antibacterial.

“…The discussion in this study includes the effect of the hand soap making practice using pineapple skin extract (Ananas comosus L. Merr) on students' learning interest. Pineapple skin extract (Ananas comosus L. Merr) contains natural compounds namely tannins which function to regenerate the skin, saponin which functions to add foam to soap and flavonoids that function as an anti-bacterial which is used as an additional material in the manufacture of hand soap (Manaroinsong, 2015;Situmeang et al 2019;Salasa et al 2019;Daely et al 2019;Yusliana et al 2019).…”

Learning by practicum method is a way of delivering learning material by providing opportunities to the students to practicein order to make the students engage in planned and active learning experiences so that students' interest grows on chemistry subject. The population in this study were the students of XI class at YAPSI Senior High School in Medan. The sampling technique is done by using the Quota sampling technique. The instruments were the student's interests in questionnaire and student activeness observation sheet. The requirements test is in the form of normality test and homogeneity test with the value of Lcount = 0.663 initial interests data and Lcount = 0.172 final interests data which means the data is normally distributed. In the homogeneity test Fcount = 0.233 initial interests data and Fcount = 0.449 final interests data with homogeneous results. The data analysis technique was done by using the hypothesis t test and N-gain test. The results showed that the hand soap making practice with the addition of pineapple extract (Ananas comosus L.. Merr) had an influence on students' learning interest with N-gain of 7.6 in experimental class data and N-gain of 5.4 in control class data and from the t hypothesis test obtained Tcount> Ttable which Tcount = 6.90 and Ttable at level 0.05 is 2.01 so Ho is accepted, which means that there was an influence of the handsoap making practice with the addition of pineapple skin extract (Ananas comosus L.
