Abstract

The use of virtual laboratories is a solution for schools that have not been able to carry out practical activities directly. This study aims to develop virtual laboratory electronic student using PjBL which can improve students' critical thinking ability. The research method used is the research and development (R & D) method with the ADDIE development model (analysis, design, development, implementation, & evaluate). The research subjects used were 30 students of class XII IPA who were selected using a purposive sampling technique. Data collection instruments consist of expert validation sheets, student response questionnaires, and critical thinking ability tests (pretest and posttest). The data analysis techniques used are Likert scale and n-gain analysis. The evaluation of the feasibility of electronic student worksheet by the expert got an average percentage of 85.41% with a very valid category, student test results got a n-gain value of 0.38 with a moderate improvement category, and the results of student responses got an average percentage value of 91.35% in the very good category. Thus, the developed virtual laboratory electronic student worksheet using PjBL can Improve students' critical thinking ability

Abstract

Kandungan kimiawi tanaman ini, seperti saponin, flavonoid, dan polifenol, menunjukkan adanya aktivitas farmakologis yang signifikan, termasuk sifat-sifat antioksidan dan immunomodulator. Selain itu, penting untuk memahami aspek toksikologi meniran guna memastikan keamanan penggunaannya dalam pengobatan. Dalam menguraikan informasi tentang pemanfaatan tradisional Meniran untuk pengobatan dan komposisi fitokimianya, penelitian ini menggunakan dua metode utama, yaitu pencarian sistematis literatur dan analisis tematik. Meniran memiliki peran yang penting dalam berbagai budaya sejak berabad-abad lalu. Tanaman ini digunakan dalam pengobatan tradisional untuk meningkatkan daya tahan tubuh, sebagai diuretik, ekspektoran, peluruh haid, penambah nafsu makan, obat demam, diare, dan penyakit kuning, dengan metode konsumsi yang beragam dari segar hingga ekstrak. Meniran memiliki potensi sebagai bahan yang berharga dalam pengobatan alami, namun perlu perhatian terhadap dosis dan efek toksikologisnya untuk penggunaan yang aman dan efektif dalam pengobatan tradisional.
