Abstract

This study aims to characterize Zno Nanoparticles’ Morphology and Crystal Structure, Respectively to Giving This Material for Further Learning to Students. The method used in this study: (i) understanding how to synthesize ZnO nanoparticles using a liquid-phase synthesis (ii) implementation of ZnO nanoparticles to students and analysis their comprehension using Transcript Based Lesson Analysis (TBLA) on the Learning Video Recording and Adaptation Learning Transcript. To support this study, several analyses were done, such as a scanning electron microscope (SEM) and X-ray diffraction (XRD) to characterize ZnO nanoparticles’ morphology and crystal structure, respectively, prior to giving this material for further learning to students. Experimental results showed that the use of ZnO is effective to improve the student comprehension. Students become more serious in listening during the learning process. They also have been more curious to study science and technology.

Abstract

Antibiotics are one of the highest used drugs in the world. Relatively high use of antibiotics can increase the risk of antibiotic resistance. Based on several studies in Indonesia, the use of antibiotics in several Public health center shows the high use of antibiotics. This study aims to find out how antibiotics are used at the Pekan Heran health center in 2019-2022 using the ATC/DDD method and to see changes in the profile of antibiotic use based on the 90% DU profile which is calculated in units of DDD/1000 KPRJ. In this study, there were 8 drugs used at Pekan Heran Public Health Center, namelyamoxicillin, clindamyycin, erythromycin, cefixime, contrimoxazol, metronidazole, chloramphanicol and cefadroxil. Data collection was obtained from the Pekan Heran Public health center. The data processing uses the ATC / DDD method which is processed using Microsoft Excel. The results show that the quantity of antibiotic use has always fluctuating during the 2019-2022 period. The highest use of antibiotic drugs was in 2019 amounting to 708,233 DDD / 1000 KPRJ, and the smallest use was in 2021 amounting to 1,157 DDD / 1000 KPRJ. The profile of the use of antibiotic drugs at the Pekan Heran Public health centerfor the period 2019-2022 was based on DU90%, namely amoxicillin, erythromycin and metronidazole. Amoxicillin is the highest drug used with a percentage in 2019, namely 48,006%, in 2020 amounting to 58,054%, in 2021 it was 27,072%, in 2022 it was equal to 28,437%

Abstract

Kesulitan mahasiswa dalam memahami materi alkana tidak dapat diatasi dengan metode pembelajaran konvensional. Penelitian ini bertujuan untuk mengetahui pengaruh metode praktikum sintesis alkana dengan menggunakan kayu manis berbasis bahan alam melalui model discovery learning terhadap motivasi dan hasil belajar mahasiswa pada materi alkana di STIKes Har-Kausyar. Penelitian ini menggunakan metode kuantitatif Quasi Experiment Design dengan menguji kemampuan subyek mahasiswa melalui pretest dan posttest control design. Hasil analisis data menggunakan uji “t” diperoleh nilai thitung = 31,62 sedangkan nilai ttabel pada taraf signifikan = 0,05 (dk=48) adalah 1,67, maka nilai thitung lebih besar dari nilai ttabel sehingga H1 diterima. Berdasarkan hasil penelitian tersebut dapat disimpulkan bahwa terdapat pengaruh positif metode praktikum melalui model discovery learning terhadap motivasi dan hasil belajar mahasiswa pada materi alkana di STIKes Har-Kausyar
