Kebun dengan ketersedian air yang cukup dapat dijadikan sebagai habitat bagi Odonata untuk bertahan hidup dan berkembang biak. Penelitian bertujuan mengetahi kelimpahan capung sepanjang Danau Kenanga hingga kebun Fakultas Ilmu Keperawatan, Universitas Indonesia, Depok, Jawa Barat. Jenis penelitian adalah penelitian deskriptif-eksploratif. Penelitian dilakukan dengan metode TTLTK (Tangkap Tandai Lepas Tangkap Kembali). Metode dilaksanakan dengan metode jalur transek, penyusuran jalur yang terdiri dari tiga jalur yaitu jalur kiri, jalur kanan, dan jalur tengah atau jalur air. Teknik analisis data menggunakan rumus indeks kelimpahan spesies dan rumus indeks keanekaragaman Shannon-Wiener. Hasil penelitian menunjukkan indeks kelimpahan dan nilai indeks keanekaragaman capung termasuk kedalam tingkatan rendah. Ditemukan capung sebanyak 52 individu yang terdiri dari 7 spesies. Pantala flavescens adalah spesies yang paling banyak ditemukan dengan jumlah individu sebanyak 41. Didapatkan pula nilai indeks keanekaragaman yakni 0.81649, termasuk kedalam kategori keanekaragaman tingkat rendah karena H’ < 1 diduga karena kondisi lingkungan mengganggu perkembang biakkan capung. Dapat disimpulkan bahwa kelimpahan capung berbanding lurus dengan keanekaragaman capung.

21st-century learning has brought out innovations in the field of education, such as learning that is no longer only done in the classroom or virtual classes with digital learning media that no longer use text alone but include audio, video, and the internet in learning. However, the development of learning media that links technology has not been optimal. Educators still have not linked videos or representative images to Biology learning, especially plant tissue and animal tissue material, so it is found that students have not mastered these materials well. This study aims to produce e-learning media that can be supported through one type of LMS (Learning Management System) application, namely Schoology, which is valid and effective on plant and animal tissue material. This research was conducted using the ADDIE model, starting from the analysis, design, development, implementation, and evaluation stages. The products developed by experts validated by 74% are in good categories, as well as the feasibility test of teachers and students who get a score of 89.60% with a very good category. The development product proved to be effective in high school learning with an increase in learning outcomes using the N-Gain test of 0.54 on plant tissue material and 0.52 on animal tissue material with moderate criteria.
