Abstract

The students' critical thinking skills are less than optimal in science learning. This study aims to develop and produce a MERDEKA flow teaching module based on outdoor learning to improve critical thinking skills in science learning in grade VII of SMP 2 Darul Hikmah, Aceh Jaya Regency. This objective is based on the results of the analysis, which shows that students' critical thinking skills are not optimal in science learning. This study uses the Research and Development (R&D) ADDIE model method with three stages, namely Analysis, Design, and Development. The analysis stage is carried out to identify students' needs and problems faced in science learning. The design stage involves planning a learning module that integrates outdoor learning activities with the MERDEKA flow. Module development is carried out by designing interactive and interesting materials and activities. The results of the study concluded that the use of the MERDEKA flow teaching module based on outdoor learning is effective in improving critical thinking skills in science learning in grade VII of SMP 2 Darul Hikmah, Aceh Jaya Regency. This can be seen from the average N Gain score of 0.806498609 with a very effective category

Abstract

This study aims to analyze the effectiveness of the implementation of the Project-Based Learning (PjBL) model based on local potential on biotechnology material in improving students' critical thinking skills and scientific attitudes. The study used a quantitative approach with a one-group pretest-posttest design for 35 students. The instruments were a critical thinking test and a scientific attitude observation sheet that had been declared valid and reliable (Cronbach's Alpha = 0.789). The results showed a significant increase in critical thinking skills, with an average pretest score of 17.63 increasing to 37.71 in the posttest, and an N-Gain value of 0.897 (high category). The increase occurred in all indicators, with the highest value in the indicator providing simple explanations (0.9226) and the lowest in the indicator organizing strategies and tactics (0.8723), but all in the high category. Students' scientific attitudes also increased, indicated by an average pretest score of 17.49 to 29.51 in the posttest, with an N-Gain value of 0.808 (high category). The highest improvement was found in the critical thinking indicator (0.93), while the lowest was in the collaboration indicator (0.63). Thus, the local potential-based PjBL model effectively improves students' critical thinking skills and scientific attitudes through contextual and project-based learning.

Abstract

Daun Kersen (Muntigia calabura L.) adalah salah satu herbal yang yang secara tradisional digunakan untuk menurunkan kadar gula darah pada pasien diabetes melitus. Tujuan penelitian ini untuk mengetahui apakah terdapat pengaruh uji ekstrak etanol daun kersen terhadap histologi hepar tikus putih (Rattus norvegicus) yang diinduksi streptozocin (STZ) Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian naratif, serta eksperimen menggunakan metode Rancangan Acak Lengkap (RAL). Penelitian ini menggunakan 5 kelompok percobaan dengan tiga kali pengulangan. Penelitian ini dilakukan pada tanggal 08 Mei sampai 22 Mei 2023. Objek dalam penelitian ini ialah 30 ekor tikus putih (yang telah diinduksi STZ sehingga menyebabkan diabetes mellitus. Analisis data dilakukan dengan pengamatan gambar melalui histopatologi hepar tikus. Hasil penelitian diperoleh bahwa pada larutan aquades (K1) terlihat gambaran normal sel hepatosit berderet secara radier pada lobulus hepar. Pada K2 (diinduksi STZ 30 mg/kilo Gram BB), sel hepatosit mengalami bengkak keruh dan nekrosis menggunakan inti piknotik, pada K3 (diinduksi STZ 30 mg/kg BB dan + obat metformin), terlihat sedikit sel yang mengalami degenerasi perlemakan dengan terbentuknya vakuolisasi lemak pada sitoplasma sel, di K4 (diinduksi STZ 30 mg/kg BB dan ekstrak daun kersen 10%), menunjukkan sel mengalami degenerasi, adanya interim, pada K5 (diinduksi streptozocin 30 mg/kgBB serta diberikan ekstrak etanol daun kersen 15%), sel hati berbentuk normal, dimana sel hepatosit berderet secara radier dalam lobulus hati. Dengan demikian ekstrak etanol daun kersen berdosis 15%, efektif dalam memperbaiki kerusakan sel di pada tubuh dampak asal zat tosik STZ sehingga dapat menurunkan kadar glukosa darah didalam tubuh.
