Bulu babi bervariasi berdasarkan jenis dan lokasi yang berbeda. Perbedaan jenis berdasarkan struktur morfologi, dan warna sedangkan lokasi berbeda secara fisik dan kimia. Penelitian ini dilakukan untuk mengetahui jenis-jenis bulu babi dan tingkat kematangan gonad bulu babi di beberapa pesisir pantai pulau Aceh Kabupaten Aceh Besar. Penelitian ini dilaksanakan bulan Januari sampai Juli 2024. Penelitian dilakukan pada beberapa lokasi pantai di Pulo Nasi yaitu Pantai Lamteng, Deudap dan Pasie Janeng, Kecamatan Pulo Aceh, Kabupaten Aceh Besar, Aceh. Penelitian menggunakan metode survey eksploratif. Hasil identifikasi di peroleh 36 individu yang terdiri dari 3 jenis bulu babi yaitu jenis Stomopneustes variolaris, dan Diadema setosum yang ditemukan di Pantai Deudap, sementara di Pantai Lamteng ditemukan Echinothrix calamaris. Berdasarkan hasil pengamatan terdapat 26 individu betina dan 10 individu jantan yang berada pada tingkat kematangan gonad mature dan memijah (4-5). Faktor lingkungan pulau nasi yaitu suhu berkisar 30-33 oC, salinitas 30-33 o/oo dan Ph 7.7-7.8. factor lingkungan tersebut masih sesuai dengan lingkungan bulu babi.

Sea urchins vary based on different types and locations. The differences in types are based on morphological structure and color, while the locations differ physically and chemically. This research was conducted to determine the types of sea urchins and the level of gonad maturity of sea urchins on several coasts of Aceh Island, Aceh Besar Regency. This research was carried out from January to July 2024. The research was conducted at several beach locations in Pulo Nasi, namely Lamteng, Deudap and Pasie Janeng Beaches, Pulo Aceh District, Aceh Besar Regency, Aceh. The research uses an exploratory survey method. The identification results obtained 36 individuals consisting of 3 types of sea urchins, namely Stomopneustes variolaris and Diadema setosum which were found on Deudap Beach, while on Lamteng Beach Echinothrix calamaris was found. Based on the results of observations, there were 26 female individuals and 10 male individuals who were at the maturity level of mature gonads and spawning (4-5). The environmental factors for Nasi Island are temperature ranging from 30-33 oC, salinity 30-33 o/oo and Ph 7.7-7.8. These environmental factors are still in accordance with the environment of sea urchins Key words: reproduction, oocytes, spermatozoa, substrate, identification, littoral.
