Methicillin-Resistant Staphylococcus aureus (MRSA) merupakan salah satu bakteri penyebab infeksi, angka kejadiannya cukup tinggi. MRSA resisten terhadap beberapa antibiotik seperti beta-laktam(18%), rifampisin (6,7%), floroquinolon (84%), linezolid (1,3%) dan ampicillin (93,4%). Ekstrak bunga cengkeh mempunyai efek antimikroba karena mengandung eugenol, flavonoid, tannin, saponin, alkaloid dan phenol yang dapat merusak struktur sel bakteri.Penelitian ini bertujuan untuk mengetahui efek antimikroba ekstrak bunga cengkeh (Syzygium aromaticum) terhadap MRSA secara in vitro.Metode yang digunakan experimental post test only group designdengan metode dilusi tabung berbagai konsentrasi ekstrak bunga cengkeh 0,39%, 0,195%, 0,097%, 0,049%, 0,024%, 0,012%, 0,006%, 0,003%. Analisis data menggunakan One Way Anova.Hasil penelitain menunjukkan Kadar Bunuh Minimal (KBM) adalah 0,39%. Uji One Way Anova p=0,000 (p<0,05) menunjukkan terdapat perbedaan signifikan antara konsentrasi ekstrak bunga cengkeh dengan jumlah koloni MRSA. Ekstrak bunga cengkeh dapat membunuh MRSA dengan cara merusak struktur sel bakteri. Kesimpulan yang dapat ditarik adalah ekstrak bunga cengkeh (Syzygium aromaticum) mempunyai efek antimikroba terhadap MRSA secara in vitro. Kata kunci : Ekstrak bunga cengkeh (Syzygium aromaticum), MRSA, KBM.
The study aims to determine the effect of audio-visual media based on ICT (Information Communication and Technology) on the introduction of English vocabulary in early childhood in group B students of TK Pertiwi Kapuhan 1 Sawangan District, Magelang Regency. This research was carried out using Pre-Experimental with the type of One Group Pretest-Posttest Design by conducting initial and final measurements. The subjects of this study were students of gruop B TK Pertiwi Kapuhan 1 Sawangan District, Magelang Regency in the 2021/2022 academic year totaling 12 students. The sampling technique in this study used purposive sampling. The data collection method is carried out using the performance method and is measured using a performance assesment sheet based on indicators. The analysis technique used is non-parametric with the Wilcoxon Ranks Test using SPSS IBM version 28.0.1.0 (142). The results showed that ICT (Information Communication and Technology) based audio-visual media had an effect on the introduction of English vocabulary in early childhood. This is evidenced by the results of the Wilcoxon ranks test, a Z value of 3.063 is obtained with a significance level of 0.002 based on the results of the attached SPSS calculation with an average comparison of the initial measurement value of 26.5 and the final measurement of 64.9 after being given treatment using ICT (Information Communication and Technology) based audio-visual media. The results of the study can be said that activities using audio-visual media based on ICT (Information Communication and Technology) affect the introduction of English vocabulary in early childhood.
This study aims to determine the appropriate science learning concept for early childhood based on the results of a literature review. Literature review research refers to the relevant study research results on the early childhood science learning topic. The results showed that there were several things related to early childhood science learning. Namely:(1) teacher competence in the science learning process, (2) basic concepts of early childhood science learning, (3) science learning program, (4) science learning process in early childhood.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
