Abstract

This study aims to examine whether or not there is an influence of the PhET-assisted problem-based learning model on student learning outcomes in Wave material. The type of research used is a quasi-experimental research design with Nonquivalent Control Group Design. The population in this study were all students in class XI MAN 1 Mataram with the sample being students in class XI MIPA 3 with a total of 31 students as the control class and students in class XI MIPA 4 with a total of 29 students as the experimental class. The test instrument used is in the form of multiple choice questions. Before the test instrument is given, the instrument is tested first, namely testing validity, reliability, difficulty level, and discriminating power. The results of the analysis showed that the average score of the physics learning outcomes of students who were taught with the PhET-assisted problem-based learning model was 79.65 and students who were taught without using PhET had an average value of 69.77. The results of testing the hypothesis using the t-test obtained a t-count of 6.45 and a t-table of 2.0017. Thus the value of t-count is greater than t-table then Ha is accepted and H0 is rejected. This means that there is an influence of the PhET-assisted problem-based learning model on student learning outcomes in class XI MAN 1 Mataram class wave material.

Abstract

Typhonium flagelliforme or known as rat taro is a herbaceous plant that belongs to the taro tribe. The results of the phytochemical analysis of the leaves and tuber extracts of rat taro are known to contain secondary metabolite compounds belonging to the class of flavonoids, alkaloids, triterpenoids, steroids, saponins, and tannins which act as antimicrobials. This study aims to determine the effectiveness of leaf, stem and tuber extracts of rat taro (Typhonium flagelliforme (Lodd)) as a biofungicide against the cause of leaf fall (Pestalotiopsis sp.) on rubber plants (Hevea brasiliensis). Leaf samples came from rubber plants at PTPN III Karet Sei Putih, Galan District, Deli Serdang Regency, North Sumatra. Pestalotiopsis sp. was isolated from plant parts showing leaf fall symptoms. Pieces of rubber leaves infected with Pestalotiopsis sp. was grown on PDA media in a petri dish and incubated for ±7 days at room temperature 26–28oC. After incubation, microscopic identification of the conidia of the fungus was carried out. In vitro test of the inhibition power of extracts of leaves, stems and tubers of rat taro against the fungus Pestalotiopsis sp. was carried out in a petri dish using the fungus culture method. The results of the phytochemical screening showed that the leaf, stem and tuber extracts of rat taro contained chemical compounds of flavonoids, tannins, saponins, alkoloids, and steroids/triterpenoids. The results showed that the leaves, stems and tuber extracts of rat taro (T. flagelliforme L.) have potential as biofungicides, K13 treatment of tuber extract of rat taro (Typhonium flagelliforme L.) 9% was the best treatment which could inhibit the growth of Pestalotiopsis sp.

Abstract

Purslane has many benefits as food or raw material for medicine. It is rich in beneficial compounds, such as omega-3 and vitamins. However, it has not been cultivated yet. Organic input in cultivation is essential to ensure food safety for humans. Using organic inputs can avoid the yield from chemical and biological contaminants that can threaten health. Thus, the source of growing media and fertilizer must be considered. Because the use of synthetic chemicals has residues that are harmful to the environment and human health. This research sought to identify the best combination of growing media and organic fertilizer to increase purslane yield. The experiment was conducted with a randomized block design with 2 factors and 3 replications. Organic fertilizers (guano, cow urine, and rabbit urine) and planting media (soil, soil + husk charcoal, soil + compost, and soil + husk charcoal) were the treatments assessed. The observation variables were planting media analysis, the number of leaves and branches, growth diameter, and fresh weight. The results show that the planting medium and organic fertilizer did not significantly affect the measured growth parameters. The single variable of organic fertilizer made a difference in growth diameter and fresh weight. Rabbit urine produced in the highest growth diameter, and guano produced in the highest fresh weight The single variable of organic fertilizer made a difference in growth diameter and fresh weight. Rabbit urine produced in the highest growth diameter, and guano produced in the highest fresh weight The single variable of organic fertilizer made a difference in growth diameter and fresh weight. Rabbit urine produced in the highest growth diameter, and guano produced in the highest fresh weight

Abstract

Black rice (Oryza sativa L.) contains chemical compounds, namely ferulic acid, -oryzanol, amino acids, tannins, phenolics, and anthocyanins which have potential as antibacterial agents. This study aims to formulate an antibacterial gel preparation from black rice extract with an extract concentration of 10% and to test the antibacterial effectiveness of the gel preparation against Staphylococcus aureus and Escherichia coli bacteria. Black rice extract was obtained by maceration using 70% ethanol solvent: 3% citric acid. The extract obtained was then formulated in a gel dosage form. The results showed that black rice extract could be formulated as an antibacterial gel preparation that met the organoleptic, homogeneity, pH, spreadability, and adhesion requirements. In the results of the antibacterial effectiveness test, there is a clear zone which represents the ability to inhibit the growth of the tested bacteria by the gel. Black rice extract can be formulated in a gel dosage form with an extract concentration of 10% and a physically stable formula is obtained in formula III with a carbopol concentration of 2%. The average diameter of the antibacterial gel FIII preparation of black rice extract in inhibiting Staphylococcus aureus bacteria was classified as strong, namely 11.17 ± 0.34 mm, while inhibition of Escherichia coli bacteria was also relatively strong, namely 12.20 ± 0.46 mm
