The development of electronic learning materials is very necessary in the midst of the COVID-19 pandemic which requires lecture activities to be carried out online. This was carried out to support physical distancing in an effort to break the chain of transmission of COVID-19. Currently, there are not many electronic learning materials available that lead to student centered learning (SCL) and can be implemented in the midst of the COVID-19 pandemic. The purpose of this research is to develop an eLEMA (Electronic Learning Material) application, an Android-based electronic learning material with content or material that can be accessed online and offline, and with features that make it easier for users to operate. This research is a research development (Research and Development; R & D) to develop Android-based ELEMA-SCL PROTOZOA (Electronic Learning Material-Student Centered Learning) for Zoology courses. This development model consists of 3 phases of approach, namely: (1) Phase 1: Needs Assessment; (2) Phase 2: Design; and (3) Phase 3: Develop / Implement. The product developed in the form of an Android-based eLEMA application made using the MIT App Inventor is feasible to implement. The implementation results show: (1) the effectiveness of online and offline lectures with a gain value of 0.52 in the Medium category; (2) student response to the implementation of eLEMA is positive. Thus the eLEMA application can be used for online and offline lectures during the COVID-19 pandemic.

Penelitian ini bertujuan mengembangkan bahan ajar digital PBL guna mendukung dan memudahkan mahasiswa dalam pemahaman konsep. Penelitian ini merupakan penelitian pengembangan (RD) dengan model ADDIE, terdiri dari 5 tahap yakni: (1) Analisis , (2) Desain , (3) Pengembangan , (4) Implementasi , (5) Evaluasi . Hasil penelitian berupa buku PBL digital untuk meningkatkan keterampilan berpikir kritis, memecahkan masalah, dan memahami suatu konsep pembelajaran melalui masalah yang disajikan pada awal pembelajaran, serta dapat digunakan sebagai bahan penunjang pada mata kuliah Zoologi Vertebrata.Hasil penelitian menunjukkan bahwa pengembangan bahan ajar PBL berdasarkan hasil validasi memperoleh kriteria sangat layak. Bahan ajar digital PBL dapat meningkatkan pemahaman konsep mahasiswa berdasarkan hasil uji N-Gain dengan nilai rata-rata sebesar 0,7 dengan kategori tinggi, dan respons siswa memperoleh nilai rata-rata 4,4 dengan kategori sangat baik.
