Abstract

The number of female medical students outweigh the number of male students in Indonesia and also in school of medicine universitas Pembangunan Nasional Veteran Jakarta has raised the awareness of identification of role of gender in student learning and student assessment. This study explored the differences of Grade Point of Average in six semesters of medical students based on gender and showed the difficult topics in learning medicine. This study was also as a preliminary study of long term evaluation of medical education process. Methods: This descriptive cohort study explored the GPA scores of medical students of year 2015 that have undergone 6 semesters. The data was analyzed for normal distribution and non parametric study was used as final step to analyze the correlation between gender and performance of medical students in 6 semesters. Result. The highest GPA score was in first semester and the lowest GPA score is in the sixth semester. After first semester, the score steps down in second semester and climbed up again in semester 3 and 4 . The score then decrease to the lowest point in semester 5 and 6. This study also showed there was no significant gender difference of variation of GPA in six semester (P 0,113) and female students have higher GPA scores than male students in all six semester. Conclusion. There was no gender difference in Grade of Point Average score in six semester of medical students in Universitas Pembangunan Nasional VeteranJakarta and semester 5 and 6 were semester that students have low GPA.

Abstract

Skin disease is still a health problem in the world, especially tropical countries, including Indonesia, it needs normal control of flora among others with antiseptic. Jatropha curcas L., which contains secondary metabolite compounds suspected as an antiseptic on the skin. The study aimed to evaluate Jatropha sap can inhibit the growth of Staphylococcus aureus, Escherichia coli, and Candida albicans, and to know the optimal concentration of Jatropha curcas by invitro. The antiseptic activity of Jatropha sap was tested using agar diffusion method (Kirby-Bauer) with Mueller Hinton Agar medium and Saboround Dextrose Agar at concentrations 20%, 40%, 60%, 80% and 100. The results showed that Jatropha sap can inhibit the growth of Staphylococcus aureus, and Escherichia coli but not in Candida albicans. Treatment of 100% Jatropha sap concentration is the most optimal concentration in inhibiting the growth of Staphylococcus aureus, and Escherichia coli with an inhibitory zone of 9.75 ± 0.27 mm (medium antiseptic power) and 10.61 ± 0.2 mm (strong antiseptic power). The results show that the sap of Jatropha curcas L. grown in Indonesia has a good potential to be used as an antiseptic made from nature.   Penyakit pada kulit masih merupakan masalah kesehatan di dunia terutama negara beriklim tropis, termasuk Indonesia, sehingga diperlukan pengendalian flora normal diantaranya dengan antiseptik. Getah jarak pagar (Jatropha curcas L.) yang mengandung senyawa metabolit sekunder diduga berfungsi sebagai antiseptik pada kulit. Penelitian bertujuan mengevaluasi apakah getah jarak pagar dapat menghambat pertumbuhan Staphylococcus aureus, Escherichia coli dan Candida albicans, dan mengetahui konsentrasi optimal getah jarak pagar secara invitro. Aktivitas antiseptik getah jarak pagar diuji dengan menggunakan metode difusi agar (Kirby-Bauer) dengan medium Mueller Hinton Agar (MHA) dan Saboround Dextrose Agar (SDA) pada konsentrasi 20%, 40%, 60%, 80% dan 100. Hasil penelitian menunjukkan getah jarak pagar dapat menghambat pertumbuhan bakteri Staphylococcus aureus, dan Escherichia coli namun tidak pada jamur Candida albicans. Perlakuan getah jarak pagar konsentrasi 100% merupakan konsentrasi paling optimal dalam menghambat pertumbuhan Staphylococcus aureus, dan Escherichia coli dengan zona hambat 9,75 ± 0,27 mm (daya antiseptik sedang) dan 10,61  0,2 mm (daya antiseptik kuat). Hasil menunjukkan getah jarak pagar yang banyak tumbuh di Indonesia mempunyai potensi yang cukup baik untuk dipergunakan sebagai antiseptik berbahan alam.   Keyword:  Antiseptik, Escherichia coli, Candida albicans, Jarak pagar (Jatropha curcas L.),  Staphylococcus aureus
