The yard of the house is an open environment around the house and is provided to support various social and economic activities related to the owner of the house. The purpose of this study was to determine the types of horticultural crops based on the Javanese in Medan. The survey method used is the survey and interview methods. The result, obtained 12 types of plants that have the potential as medicinal plants and 2 types of plants that have the potential as ornamental plants. All types of plants have medicinal properties, this shows that the home garden has many benefits in providing potential types of plants, especially the daily needs of the family.

“…This inhibitory activity can occur because hibiscus flowers contain active antimicrobial compounds such as flavonoids, saponins, tannins and alkaloids. [19][20][21] Flavonoid phenol groups with their antibacterial mechanism, namely protein denaturation and damage to cell membranes. 15 Saponins have an antibacterial mechanism by reducing surface tension, resulting in increased permeability and release of intracellular compounds.…”

Background: Streptococcus sp colonies are Gram-positive coccus bacteria that play a role in the formation of dental plaque and cause dental caries. However, dental caries can be prevented with the gold standard mouthwash, namely chlorhexidine. In other studies, many mouthwashes have been developed using traditional ingredients that have antibacterial potential, one of which is hibiscus flower (Hibiscus rosa sinensis L.). This is due to the presence of chemical compounds that can inhibit the growth of Streptococcus sp in dental plaque.Objectives: Testing the effectiveness of 0.2% chlorhexidine and H. rosa sinensis L. extract against Streptococcus sp in dental plaque.Method: Laboratory experimental research with pre and post test only control group design on 6 groups. Group K- (aquades), K+ (chlorhexidine), H. rosa sinensis L. extract 6.25% (P1), 12.5% (P2), 25% (P3), 40% (P4). Each of these groups consisted of 4 subjects. Data were obtained by counting the number of Streptococcus sp colonies before and after gargling which had been streak-cultured on blood agar media. The statistical analysis used the Shapiro Wilk test showed significant results P ≥ 0.05, followed by the One Way ANOVA parametric test. While the not significant results with the Kruskall Wallis non-parametric test.Results: There was a significant difference between the 4 concentrations of H. rosa sinensis L. extract 6.25% (P1), 12.5% (P2), 25% (P3), and 40% (P4) with the control (+) (p = 0 .00), and at a concentration of 25% (P3) effectively inhibited the growth of Streptococcus sp bacteria by 12.5%.Conclusion: H. rosa sinensis L. extract was effective compared to 0.2% chlorhexidine in inhibiting the growth of Streptococcus sp. Administration of various concentrations of H. rosa sinensis L. mouthwash extract inhibited the growth of Streptococcus sp, and at a concentration of 25% (P3) effectively inhibited Streptococcus sp by 12.5%.

“…Hasil penelitian untuk respon rendemen diperkuat dengan penelitian yang dilakukan Agustin & Ismiyati (2015) yang menyatakan bahwa hasil rendemen antosianin kembang sepatu menurun seiring dengan pertambahan konsentrasi pelarut. Hal tersebut disebabkan karena semakin besar fraksi etanol maka akan semakin banyak yang menguap, mengingat titik didih etanol yang lebih rendah dibandingkan air.…”

“…Semakin besar jumlah etanol yang digunakan maka kontak bahan dengan etanol yang berfungsi sebagai media ekstraksi juga lebih besar sehingga berpotensi memaksimalkan hasil rendemen ekstrak (Anam, 2010). Menurut Agustin & Ismiyati (2015), hasil rendemen semakin menurun seiring dengan pertambahan konsentrasi disebabkan karena semakin besar fraksi etanol maka akan semakin banyak yang menguap mengingat titik didih etanol yang lebih rendah dibandingkan air. Selain itu, berat jenis etanol yang lebih rendah dibandingkan air dapat memengaruhi bobot ekstrak yang diperoleh.…”

Kandungan polifenol dalam kopi hijau berpotensi menurunkan akumulasi lemak viseral sehingga dapat menurunkan kadar kolesterol total secara signifikan. Kopi hijau memiliki rasa kurang nikmat ketika dikonsumsi, sehingga perlu penelitian mengenai ekstraksi polifenol untuk diolah sebagai produk bernilai jual tinggi. Tujuan dari penelitian ini adalah optimasi kombinasi konsentrasi dan rasio penambahan pelarut yang optimal dalam menghasilkan rendemen dan kadar fenol tertinggi pada proses ekstraksi senyawa polifenol biji kopi hijau. Metode optimasi yang digunakan adalah Response Surface Method dengan Central Composite Design. Penelitian dilakukan menggunakan dua variabel optimasi yaitu konsentrasi pelarut etanol (60–90%) dan rasio pelarut (20–40 ml/g). Respon yang diukur adalah total fenol dan rendemen ekstrak. Kondisi optimum yang diperoleh adalah pada ekstraksi menggunakan konsentrasi pelarut 84,92% dan rasio 40 ml/g dengan desirability sebesar 0,87. Hasil prediksi program menghasilkan total fenol sebesar 534,50 mg GAE/g dan rendemen ekstrak 17,179%. Hasil verifikasi solusi optimal adalah total fenol sebesar 538,83 mg GAE/g dan rendemen 15,39%.
