Abstract

Sistem blok merupakan metode pembelajaran student-centered yang telah banyak diterapkan di institusi pendidikan Kesehatan di Indonesia. Banyak mahasiswa baru mengalami kesulitan dalam beradaptasi dengan situasi pembelajaran mereka, dimana sebelumnya metode pembelajaran mereka adalah teacher-centered dan kini berubah menjadi student-centered. Matrikulasi merupakan program penyesuaian yang diselenggarakan oleh perguruan tinggi dengan tujuan untuk mempercepat kemampuan adaptasi akademik maupun non-akademik mahasiswa baru di perguruan tinggi. Penelitian ini bertujuan untuk mengetahui efektivitas pembelajaran sistem blok selama matrikulasi terhadap tingkat pengetahuan mahasiswa Program Studi S1 Kedokteran Universitas Tanjungpura. Penelitian ini merupakan penelitian kuantitatif menggunakan metode eksperimen dengan jenis penelitian berupa quasi experimental. Rancangan yang digunakan pada penelitian ini merupakan one group pre-test post-test design. Teknik pengumpulan data dilakukan dengan menggunakan kuisioner. Sampel diambil dengan metode total sampling yaitu sebanyak 78 mahasiswa. Hasil penelitian menunjukkan persiapan belajar yang dilakukan oleh mahasiswa dalam menghadapi post-test tidak berdampak signifikan terhadap kelulusan mereka berdasarkan standar nilai yang digunakan di jurusan kedokteran (α = 0.233). Kegiatan matrikulasi terbukti secara signifikan meningkatkan pengetahuan peserta, namun tidak cukup baik untuk mendapatkan predikat lulus berdasarkan sistem penilaian.

Abstract

Jamu cekok, an Indonesian traditional medicine to increase children appetite, has not passed preclinical or clinical trials. The rhizomes that make up jamu cekok such as pakai bahasa latinnya contain ethyl p-methoxycinnamate which is toxic, thus potentially harmful to the children. Therefore in this study we aim to determine the Lethal Dose (LD50) value of jamu cekok using the OECD 425 method as well as to observed the histopathological change in the liver in female Rattus norvegicus L. This study used an analytical experimental design with the OECD 425 method to test the acute toxicity of jamu cekok. The test rats used were in accordance with the OECD 425 protocol with an additional 2 negative control rats. Jamu cekok in the form of decocta were given once on the first day of the acute toxicity test and observed for 14 days. On the 15th day, rats were euthanized, dissected, and hepatic organs were taken to make histopathological preparations with Hematoxylin-Eosin staining. Analysis of hepatic damage was assessed using Histopathology Scoring Manja Roenigk and tested by Kruskal Wallis method. The results showed the LD50 value of decocta extract of jamu cekok was >5000 mg/kgBB. Observations of body weight, behavioral tests, organ index, and macroscopic hepar of test rats showed no signs of toxicity. However, The statistical analysis for histopathology test showed that there was a significant difference (p<0.05) between the negative control group and the 5000 mg/kgBB treatment group. In conclusion, the administration of jamu cekok was categorized as practically non-toxic but it can caused reversible hepatic damage at a dose of 5000 mg/kgBB.
