Abstract

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.

Abstract

Vanilla (Vanilla planifolia Andrews) is a plantation plant that is used for its fruit. Indonesia is one of the countries that exports vanilla and has climate factors that support increasing vanilla production to meet global demand, One of the efforts that can be made in vanilla propagation is through plant tissue culture. This research aims to induce calluses. This study used a Random Design using stem explants and several different hormone concentrations, namely: 0.0 ppm NAA and 0.0 ppm Kinetin, 1.0 ppm NAA and 0.5 ppm Kinetin, 1.0 ppm NAA and 1.0 ppm Kinetin, 2.0 ppm NAA and 0.5 ppm Kinetin, 2.0 ppm NAA and 1.0 ppm Kinetin, 2.0 ppm NAA and 2.0 ppm Kinetin. There was an effect on the administration of NAA and Kinetin on callus induction in the explants of the vanilla plant (Vanilla planifolia Andrews). It is based on the Anova one-way Hypothesis Test with a significance value of 0.000 (Asymp. Sig <0.05) then Ho was rejected and H1 was accepted. The optimal concentration to induce callus in stem explants is the administration of 1.0 ppm NAA + 0.5 ppm Kinetin with an average callus growth rate of 7 HST and a 100% callus growth percentage of explants.   Keywords: Vanilla, induction, callus, tissue culture, hormones

Abstract

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.

Abstract

Clean water is a basic need for society. However, the problem of clean water sources still occurs in the Ogan Komering Ilir (OKI) area of South Sumatra Province. The condition of the water being brownish and oily is an unresolved problem. One source that has the potential to disrupt water quality is the presence of factories around rivers. This community service activity aims to identify water quality and provide training to the community regarding river water management strategies and drilled wells as the primary water source for obtaining clean water, as well as increasing understanding and knowledge about clean water management with the Gravity-fed Filter Technique. The method of activities related to clean water quality is carried out in four stages, namely: 1) Location survey (cross-sectional), 2) Water sampling and laboratory analysis, 3) Education on water quality standards, and 4) Training on Gravity-fed Filter Techniques. The laboratory analysis showed that the water samples smelled fishy and were brownish and oily. In addition, the results of microbiological tests on water samples contained Coliform bacteria (sanitation indicator bacteria), which were outside the provisions of Minister of Health Decree No. 907/MENKES/SK/VII/2002 concerning clean water quality requirements. Through training activities using the Gravity-fed Filter technique, the pH and bacteria contained in the water can be reduced. Clean water management strategies using the Gravity-fed Filter technique can be used as a solution to improve clean water quality. Every society can apply the Gravity-fed Filter technique. Through this activity, society has managed water sources into clean water for daily needs.

Abstract

Metacognitive skills help students think, manage their knowledge, analyze and solve problems, understand their learning methods and strategies, and think critically. Guided inquiry learning trains students to think critically, analyze, evaluate, and build information based on their acquired knowledge. This study aims to investigate students' metacognitive skills through guided inquiry learning on the material of Plant Structure and Function. The type of research used is Pre-Experiment with One-Group Pretest-posttest design. The sampling technique used saturated samples with a sample size of 19 students. The research instruments used were pretest and posttest questions on metacognitive skills with planning, monitoring, and evaluation indicators. Data analysis used the Wilcoxon non-parametric test. The results of the increase in cognitive skills in the pretest and posttest were indicated by the N-gain value of 0.59 with the Medium category. The results of the data analysis obtained the Asymp value, sig < 0.5, which is 0.00, which means that HI is accepted. This shows that learning using guided inquiry can affect students' metacognitive skills.
