The test consisted of six texts where each text contained eight questions with five options (A,B,C,D and E). The writer conducted a try out before the treatment was held. The level difficulty formula by Heaton was used in this study to obtain the reliability and validity of the test. Furthermore, the t-test formula was used in order to analyze the data. The T-Test displayed that the results determined by the probability of sig. > 0.05, probability=0.000, that showed a strong correlation between Collaborative Strategic Reading (CSR) and students’ reading comprehension. t-obs result also showed that the students’ mean score of the post-test (67.04) was higher than the pre-test ( 54.59). Besides, the results of the analysis showed that the t-test was higher than the t-table (12.45>2.028) at the level sig. of 0.05 with the degree of freedom (df) n-1=36. It means that the alternative hypothesis was accepted and null hypothesis was rejected. Based on the data calculation, the results showed the significant effects of Collaborative Strategic Reading (CSR) towards the reading comprehension of the first grade students.Keywords: Collaborative Strategic Reading (CSR), reading comprehension

Abstract

Biji Buah Nangka (Artocarpus heterophyllus L.) dilaporkan memiliki aktivitas sebagai antihiperglikemia. Pada penelitian ini bertujuan menguji ekstrak etanol 70% biji nangka dan diharapkan dapat dimanfaatkan sebagai penurun kadar gula darah tikus diabetes gestasional yang diinduksi streptozotocin. Hewan uji tikus betina bunting galur Sprague dawley dibagi 6 kelompok perlakuan, masing-masing terdiri dari 4 ekor tikus. Kelompok I (kontrol normal), kelompok II (kontrol negatif), kelompok III (kontrol positif) diberi metformin dosis 51.37 mg/kgBB, kelompok IV (Dosis Uji 100 mg/kgBB), kelompok V (Dosis Uji 200 mg/kgBB) dan kelompok VI (Dosis Uji 400 mg/kgBB), kelompok IV,V dan VI diberi sediaan uji biji buah nangka secara oral. Tikus diinduksi terlebih dahulu dengan streptozotocin agar tikus mengalami hiperglikemia, kemudian diberi perlakuan sediaan uji selama 14 hari. Pengambilan darah dilakukan pada hari ke-14, untuk menghitung kadar glukosa darah menggunakan fotometer klinikal. Hasil uji ANOVA satu arah menunjukkan adanya perbedaan antar kelompok perlakuan. Semua kelompok sediaan uji ekstrak biji buah nangka memiliki aktivitas menurunkan kadar glukosa darah terhadap tikus diabetes gestasional. Hasil uji Tukey penurunan kadar glukosa darah menunjukan kelompok uji sediaan biji nangka dosis 400 mg/kg BB sebanding dengan kelompok positif yang diberikan Metformin 51.37 mg/kgBB.
