The stevia plant (Stevia rebaudiana B.) is found in the United States, and is often used as a mixture in drinks. In Indonesia, cultivation of stevia began in 1977 in West Java and Central Java. The natural sweetener content with low calories makes stevia a solution for diabetes sufferers. Conventional cultivation takes a long time and depends on soil conditions, climate and variety. Tissue culture is used for plant propagation in a short time, free of pests and diseases, and does not depend on the season. Growth Regulators (ZPT) such as kinetin are used to accelerate shoot growth. The tissue culture media used is Murashige Skoog (MS). This study aims to examine the effect of kinetin on shoot induction in stevia explants through tissue culture, with explants in the form of leaf petioles. This study used a Completely Randomized Design (CRD) with kinetin concentrations of 1 ppm, 2 ppm, 3 ppm and 4 ppm. The results of the research showed that all kinetin treatments on leaf petiole mother explants were able to form shoots with an average percentage of 100%. But it didn't show any influence.

AbstractResearch using ethanol extract from black cumin seeds aims to find out whether black cumin seed extract (Nigella sativa) can be effective in increasing the stamina of male mice. The research design used was a completely randomized design (RAL). The samples used were 24 male mice consisting of four treatments and six repetitions. The dosing treatment consisted of a normal control group (P0), 30 mg/kg weight (P1), 60 mg/kg weight (P2), and 120 mg/kg weight (P3). The swimming test method was used to determine the effect of increasing stamina on mice. Data on the swimming duration of mice were analyzed using the ANOVA test then continued using the Post Hoc Test, namely LSD. The average stamina of mice based on swimming duration was the highest, namely at a dose of 120 mg/kgW (P3). Administration of black cumin seed extract (Nigella sativa) at doses of 30 mg/kgBW, 60 mg/kgW, and 120 mg/kgW for 14 days provided effectiveness in increasing stamina in male white mice (Mus musculus) as indicated by an increase in the swimming duration of the mice in each treatment.AbstrakPenelitian menggunakan ekstrak etanol biji jinten hitam bertujuan untuk mengetahui apakah ekstrak biji jinten hitam (Nigella sativa) dapat berpengaruh terhadap peningkatan stamina mencit jantan.

Nepenthes mirabilis is an endemic plant of Sumatra that has been classified as endangered since 2014. This plant needs to be conserved to prevent its extinction. One of the methods that can be applied to overcome the threat of extinction is plant propagation through modern tissue culture technology. Using this method, plant breeding can be carried out in a relatively short time, in large quantities, and without depending on seasonal conditions. The aim of this research is to conserve this rare species through experimental approaches using a completely randomized design. The data were analyzed both descriptively and quantitatively. In this study, variations of kinetin hormone concentrations were applied (0 ppm, 0.25 ppm, 0.50 ppm, 0.75 ppm, 1.0 ppm, 1.25 ppm, 1.50 ppm, 1.55 ppm, and 2.00 ppm). The best results were obtained at a concentration of 1.50 ppm, with the highest average number of leaves (8.00 ± 0.000) and the longest leaf length (8.083 ± 0.022 cm). These findings indicate that the application of kinetin at certain concentrations can accelerate the propagation of Nepenthes mirabilis seedlings in vitro, producing more plantlets in a shorter period of time, and without seasonal limitations. Therefore, tissue culture techniques with the addition of kinetin hormone can serve as an effective solution to support the conservation and sustainable propagation of Nepenthes mirabilis. Keywords: conservation, Hormone, pitcher plant, propagation, tissue culture
