Abstract

This study aims to determine the learning outcomes of students using the Problem Based Learning model on the material "I and my needs". The type of research used Pre-Experimental Design with a One-Group Pretest-Postest Design research design. The subjects used were all fourth grade students of UPTD SD Negeri Oebobo 2 totaling 27 people. The sampling technique used the Non Probability sampling technique with saturated sampling, where the entire population was sampled. Data collection techniques and instruments in the form of tests and observation sheets. The test instruments given were in the form of pretests and posttests to measure learning outcomes. Before being used, the test instruments were first tested for validity and reliability. After the data was collected, they were analyzed using a hypothesis test. The results showed that the average posttest score was 84.07> the average pretest score of 57.96. In addition, the results of hypothesis testing with a paired sample T-test showed that the significance value (2-tailed) was 0.000. This shows that the significance level value (2-tailed) <0.05, according to the basis for making this test decision that if the significance level value (2-tailed) <0.05, then the learning outcomes differ significantly between the pretest and posttest data. Therefore, the results of the study indicate a significant influence between the Problem Based Learning model assisted by smart board media on the learning outcomes of science subjects and the needs of grade IV students of UPTD SD Negeri Oebobo 2.

Abstract

Nosocomial infections caused by Staphylococcus aureus are increasing and have become a serious problem because this bacterium can grow rapidly and is difficult to treat. The use of medicinal plants as alternative therapies has therefore gained attention, one of which is kucing-kucingan (Acalypha indica L.). This study aimed to analyze the effect of kucing-kucingan (Acalypha indica L.) root extract on the growth of Staphylococcus aureus and to determine the concentration of root extract from Kupang City that can inhibit and kill Staphylococcus aureus. The method used was a laboratory experimental design employing the dilution method to determine the MIC (Minimum Inhibitory Concentration) and MBC (Minimum Bactericidal Concentration), with each treatment performed in triplicate. The concentrations of kucing-kucingan (Acalypha indica L.) root extract used were 300 mg/mL, 600 mg/mL, and 900 mg/mL. Sterile distilled water was used as the control. The results showed that higher concentrations of kucing-kucingan (Acalypha indica L.) root extract resulted in greater inhibition of Staphylococcus aureus growth. The MIC was observed at the lowest concentration, 300 mg/mL, with Staphylococcus aureus growth of 156,33 CFU, while at the highest concentration, 900 mg/mL, bacterial growth decreased to 67,66 CFU. In this study, no MBC activity of kucing-kucingan (Acalypha indica L.) root extract was observed. Thus, kucing-kucingan (Acalypha indica L.) root extract has potential as a natural antibacterial alternative for nosocomial infections caused by Staphylococcus aureus.
