Self assessment dilakukan oleh mahasiswa itu sendiri, sedangkan peer assessment didapatkan dari lima orang mahasiswa lain yang pernah berada dalam satu kelompok dengan subjek. Hasil penelitian menunjukkan untuk mahasiswa tingkat dua terdapat korelasi bermakna self assessment dan peer assessment dengan nilai OSCE (p<0,001), arah hubungan antara keduanya positif, serta kekuatan hubungan keduanya sedang (R=0,426). Pada mahasiswa tingkat empat terdapat korelasi bermakna antara self assessment dan nilai OSCE (p<0,001) dengan kekuatan hubungan keduanya sedang (R=0,451), serta terdapat korelasi yang bermakna antara penilaian peer assessment dan nilai OSCE. Simpulan, self assessment mempunyai korelasi positif terhadap nilai kelulusan OSCE pada mahasiswa tingkat dua dan tingkat empat, sedangkan peer assessment mempunyai korelasi positif dengan nilai kelulusan OSCE hanya pada mahasiswa tingkat dua. Self assessment mempunyai korelasi positif dengan peer assessment pada mahasiswa tingkat dua dan tingkat empat FK Unisba tahun akademik 2012/2013.

Background: Cigarettes smokes are a great external source of free radicals. The negative effects of cigarette smoke exposure can be systemic and affect all body systems, including the reproductive. Male rats exposed to cigarette smoke have a risk of oxidative stress and sperm damage. This can be overcome with herbal antioxidants such as white oyster mushrooms (Pleurotus ostreatus).Objective: This study aimed to examine the protective effect of ethanolic extract of white oyster mushroom against damage to sperm morphology of rats exposed to cigarette smoke.Methods: This study is an experimental study using 40 rats which were divided into 5 groups. Group I (normal control), group II (negative control) were only given exposure of cigarette smoke, Grups III, IV and V (treatments groups 1, 2, and 3) were given exposure of cigarette smoke and ethanolic extract a dose of 125, 250, and 500 mg/Kg BW/day for 14 days. On the 15th day, the percentage normal rat sperm were calculated under a 400x magnification microscope.Results: Normal sperm count in group I was 79% ± 0.79, group II was 39% ± 0.55, Grup III, IV and V were 56% ± 0.15, 65% ± 0.54 and 66% ± 0.21.
