The purpose of this study was to determine the biodiversity of Echinodermata on Tidung island. This study was conducted on February 2019 using purposive sampling method. Data collection was performed using belt transect method and data were analyzed quantitatively by calculating Echinoderm’s abundance relativity index and species diversity index and compare the data on each substrate. Based on observations of Echinoderms species diversity on Tidung island, belongs to low to moderate level with a value of 0.8269 - 1.0057 and abundance is mostly found at station 2 with a value of 52.5%, of Ophiomastix sp. totaled 21 individuals and salinity at station 2 was 28%

Senyawa flavonoid dan terpenoid diketahui merupakan metabolit sekunder tanaman yang memiliki aktivitas antioksidan tinggi. Tanaman yang mengandung flavonoid dan terpenoid berpotensi untuk digunakan sebagai sumber antioksidan alami. Oleh karena itu, tujuan dari penelitian ini adalah untuk membuktikan adanya senyawa flavonoid dan terpenoid pada tumbuhan famili Fabaceae dan Apocynaceae di PPKA Bodogol. Penelitian ini dilaksanakan pada tanggal 19 Juni sampai dengan 22 Juni 2021 di TNGGP PPKA Bodogol, Sukabumi, Jawa Barat. Pengambilan sampel tumbuhan dilakukan dengan metode purposive sampling sedangkan untuk mengetahui kandungan metabolit sekunder dalam sampel dilakukan skrining fitokimia melalui uji warna, pengujian bahan dilakukan secara skala lapangan. Hasil penelitian menunjukkan bahwa daun Hoya multiflora dari famili Apocynaceae mengandung senyawa flavonoid dan terpenoid. Sementara itu, Alstonia sp. dari famili yang sama hanya mengandung senyawa terpenoid. Daun Calliandra sp. dari famili Fabaceae yang teridentifikasi mengandung senyawa flavonoid dan terpenoid. Sedangkan, daun Centrosema pubescens dari famili Fabaceae hanya mengandung senyawa flavonoid. Kata kunci : Apocynaceae, Fabacae, Fitokimia, Flavonoid,Terpenoid.

The goal of this research is to develop valid and feasible Nearpod-based circulation system teaching materials. This research method uses the ADDIE development model, which includes stages of analysis, design, development, implementation, and evaluation. The research was conducted from July 2022 to June 2023. The teaching materials were tested for feasibility in material, media, and language and tested by Biology teachers and students of SMAN 14 Jakarta. The feasibility test results showed that Nearpod-based circulation system teaching materials had an average score of 3.65 (very valid) on the material aspect, 3.89 (very valid) on the media aspect, and 3.53 (very valid) on the language aspect. In Biology, the teacher trial obtained a mean value of 3.51 and an average of 3.31 for the student trials. This shows that Circulapod teaching materials are very valid and feasible to be used as learning media for circulatory systems learning in schools.
