"> Penelitian ini bertujuan untuk mengetahui (1) kemampuan kognitif yang dilihat dari hasil belajar peserta didik yang kelas XI MAN Model Palangka Raya dalam mengerjakan soal-soal uraian terstruktur pada pokok bahasan Teori Kinetik Gas; dan (2) kesulitan peserta didik dalam mengerjakan soal-soal uraian terstruktur. Penelitian ini menggunakan metode penelitian kuantitatif dalam mengumpulkan datanya. Penelitian ini menggunakan instrumen dalam bentuk soal uraian terstruktur. Hasil uji coba soal uraian terstruktur pada kelas XI IA-1 MAN Model Palangka Raya mendapatkan tingkat validitas rata-rata 0,536 dan tingkat reliabilitas soal 0,539 dengan kategori cukup. Hasil penelitian menunjukkan bahwa: (1) peserta didik yang mampu dan tidak mengalami masalah dalam mengerjakan soal-soal uraian terstruktur berjumlah 18 peserta didik dan 12 peserta didik tidak mampu dan mengalami masalah dalam mengerjakan soal-soal uraian terstruktur. Peserta didik yang mampu mengerjakan soal-soal uraian terstruktur memiliki ketuntasan belajar ≥ batas KKM, yaitu 60% (2) kesulitan peserta didik dalam mengerjakan soal-soal uraian terstruktur terdapat pada penyebutan dan penulisan satuan besaran pada jawaban dengan persentase kesulitan 36,7%, penguasaan operasi hitungan denganpersentase kesulitan 31,4% dan penulisan besaran yang ditanya dalam soal dengan persentase kesulitan 28,6%

Soluble insulin analogs combining rapid- and long-acting hypoglycemic properties – From an efficient <i>E</i>. <i>coli</i> expression system to a pharmaceutical formulation - Fig 4

<p><b>a-d. The influence of multiple dose administration of tested insulin analogs (GKR, GEKR, SR and AKR) positive (insulin glargine or insulin detemir) and negative (0.9% NaCl) controls on glucose concentration in streptozotocin-induced diabetic rats, together with the period after termination of analogs administration. Mean glycemia (± SEM).</b> Star–statistical significance (p<0.05) confirmed in a Newman-Keuls between one of the tested groups (GKR, GEKR, SR or AKR) and a negative control group (0.9% NaCl) at the individual sampling time point. Diamond–statistical significance (p<0.05), confirmed in a Newman-Keuls test during the administration period or in a t-test after stopping insulin administration, between one of the tested groups (GKR, GEKR, SR or AKR) and a positive control (insulin glargine or detemir) at the individual sampling time point. N–Number of tested animals per group.</p
