Abstract

The objective of this study is to investigate the effect of practicum method on student learning outcomes in the subject matter of optical tools in grade XI semester II SMA Swasta Asisi T.P. 2022/2023 with the application of practicum method.The type of research is true experiment with the sample from grade XI MIA 1 and XI MIA 2 of SMA Swasta Asisi T.P. 2022/2023. The instrument test of research was composed 20 items of multiple choice and the validity of the content was tested by two experts as the validator and the observation sheet of the student activity. Based on the result of the data analysis, the mean value of post test in  experimental class postes 78.46 with the standard deviation of 11.25 and the mean value of post test in control class 66.50 with the standard deviation of 13.78. Normality and homogeneity test at level α=0.05 stated normal and homogeneous and test of hypothesis was only one thitung > ttabel (2.99 > 1.67). It can be concluded that the using of  practicum method can improve the student’s achievement in the subject of optical tools in grade XI semester II SMA Swasta Asisi T.P. 2022/2023.

Abstract

Infections caused by Salmonella typhi remain a serious global health problem, particularly due to the increasing bacterial resistance to conventional antibiotics. Therefore, the search for effective natural antibacterial sources is urgently needed. Rhizophora apiculata, a mangrove plant known to contain various bioactive compounds, has the potential to be an alternative antibacterial source. This study aims to identify the phytochemical content in R. apiculata fruit extract and evaluate its antibacterial activity against S. typhi using the disc diffusion method and bacterial cell morphology analysis via SEM. The phytochemical screening results revealed that the extract contains phenolics, tannins, alkaloids, and flavonoids. However, saponins and steroids were not detected. The antibacterial activity test showed that the extract at a concentration of 250 mg/mL significantly (p < 0.05) inhibited the growth of S. typhi, with the largest inhibition zone (11.6 mm). SEM observations supported this finding by showing a decrease in the number of bacterial cells at extract concentrations of 125 mg/mL and 250 mg/mL, where the highest concentration caused the most bacterial cell death. This study demonstrates the potential of R. apiculata fruit extract as an effective natural antibacterial source for the development of alternative treatments for S. typhi infections

Abstract

Pembelajaran yang aktif dan inovatif sangat diperlukan untuk meningkatkan hasil pembelajaran siswa, khusus kurikulum merdeka saat ini program pemerintah khususnya kementrian bagian pendidikan berusaha meningkatkan literasi dan numerasi siswa oleh karena itu bentuk pelatihan perlu dilaksanakan bagi guru-guru sekolah dasar. Salah satu Sekolah Dasar (SD) yang ada di Kabupaten Simalungun khususnya kecamatan Jorlang Hataran adalah SD Negeri 096465 yang berlokasi di Bah Bunian. Pengabdian ini akan dilakukan di sekolah ini karena sekolah ini bersedia menjadi mitra dalam melakukan pengabdian. Metode pelatihan mencakup pemaparan materi, diskusi interaktif, studi kasus, serta praktik langsung melalui microteaching. Hasil kegiatan menunjukkan adanya peningkatan pemahaman peserta terhadap konsep pembelajaran aktif dan inovatif, serta kemampuan mengintegrasikan aspek literasi dan numerasi dalam Rencana Pelaksanaan Pembelajaran (RPP). Pelatihan ini diharapkan menjadi langkah awal yang berdampak pada peningkatan kualitas pembelajaran dan hasil belajar siswa secara berkelanjutan di era Kurikulum Merdeka
