Abstract

Tujuan penelitian ini adalah mengetahui ada atau tidaknya pengaruh yang positif menggunakan Laboratorium Virtual terhadap Minat  belajar mahasiswa pada mata kuliah Praktikum Biokimia. Berdasarkan hasil dari kuesioner responden sebesar 91,04% mengalami kesulitan mengalami kesulitan selama belajar daring dalam melakukan Praktikum Biokimia. Serta Materi praktikum biokimia selama daring termasuk materi yang sulit dipahami dengan persentase sebesar 52.23%. Penelitian ini merupakan penelitian Kuantitatif Deskriptif, sampel dalam penelitian ini yaitu mahasiswa semester 5 Prodi Pendidikan Kimia. Sampel yang digunakan Probability Sampling dengan teknik Simple Random Sampling.  Laboratorium Virtual sangat berpengaruh besar terhadap minat belajar mahasiswa selama pembelajaran daring masa pandemi saat ini.

Abstract

This research is a development research that produces teaching materials based on project-based learning (PjBL) on acid-base theory, pH solutions and acid-base titrations for class XI IPA. The development model used is the Four Steps Teaching Material Development (4S-TMD). Data collection was carried out by interviews, questionnaires, validation and tests. The results of the validation of teaching materials developed from the three aspects material, pedagogic, and design, obtained an average validity score of 0.93 in the high category and declared valid. The practicality test results that have been carried out and analyzed obtain a practicality value of 0.80 where the score is categorized as high so that it is considered practical. The results of the effectiveness test of teaching materials by looking at student learning outcomes based on pretest and posttest scores are then calculated for the N-Gain. The N-Gain score obtained was 0.72 where the score was in the high category range and was declared effective. Thus the project-based learning-based teaching materials that have been developed are stated to be valid, practical and effective so that they are suitable for use in the chemistry learning process for acid-base theory , pH solutions and acid-base titrations in class XI IPA.
