Efektifitas Model Guided Discovery Learning Terhadap Kemampuan Pemecahan Masalah Materi Bangun Ruang Kelas V

The background of this research is students who experience difficulties in solving mathematical problems, students who have not mastered the basic concepts of geometric shapes, learning models have not been able to stimulate students in solving mathematical problems. The research objective was to determine the effectiveness of the guided discovery learning model on the ability to solve geometric material problems. This research is an experimental research with a True-Experimental design and uses a pretest-posttest control group design. The sample in this study were fifth grade students consisting of two classes, each consisting of 24 students. The results of this study show the calculation of the average increase in the experimental class and control class, reinforced by the results of the t-test obtaining a significance value of 0.03. Where the significance value is less than 0.05 (0.03 <0.05) then H0 is rejected. So that the guided discovery learning learning model is better than the problem solving abilities of students who take part in conventional learning. Mastery learning in the experimental class with a classical score percentage of 92% and 79% classical value in the control class, so that the guided discovery learning model is said to be effective in improving problem solving abilities

Pemeriksaan Serologi Anti SARS-CoV-2, Pemberian Vitamin C Dan Zinc Pada Dokter Muda Fakultas Kedokteran Universitas Jenderal Achmad Yani

Kejadian COVID-19 di Indonesia selalu mengalami peningkatan. Pemberian vitamin C dan zinc pada dokter muda Fakultas Kedokteran Universitas Jenderal Achmad Yani bertujuan untuk memberikan kontribusi dalam pencegahan COVID-19 terhadap dokter muda yang masuk dalam kelompok beresiko tinggi. Kegiatan ini diharapkan dapat menjadi salah satu upaya pencegahan yang dilakukan untuk menekan angka kejadian COVID-19.  Kegiatan diawali dengan pembagian kuesioner kriteria COVID-19 dari Kemenkes RI, dilanjutkan dengan pemeriksaan serologis Anti SARS-CoV-2 untuk mengetahui status COVID-19 dari dokter muda. Sebanyak 47 dokter muda yang terdiri dari 32 perempuan dan 15 laki-laki berusia rata-rata 22 tahun, memiliki status kontak erat berdasarkan kuesioner, dan empat diantaranya (8,51%) dokter muda memiliki hasil reaktif. Hasil Anti SARS-CoV-2 pada kegiatan ini bukan sebagai diagnosis pasti, sehingga untuk hasil reaktif diperlukan pemeriksaan ulang dengan Swab-PCR, melakukan physical distancing serta perilaku hidup bersih dan sehat
