The coastal region of Sabu Raijua exhibits significant potential for the development of seaweed aquaculture. In addition to favorable oceanographic conditions, local communities in the area posess valuable indigenous knowledge in the sustainable utilization of marine resources. This potential can be further enhanced through adaptive strategies that align with environmental conditions, such as selecting seaweed strains tolerant to salinity and managing cultivation periods based on seasonal variations. This study aims to assess the suitability of cultivating Eucheuma cottonii in the coastal area of Sabu Raijua, with an emphasis on oceanographic characteristics. Data were obtained through direct field measurement and water sampling conducted at several prospective cultivation sites. The observed parameters, included water depth, type of substrate, temperature, pH, salinity, and dissolved oxygen (DO), measured at 8 stations. The results indicate that the coastal waters of Sabu Raijua conducive to seaweed cultivation. However, station II and VIII were identified as less suitable due to their shallow depth and low dissolved oxygen concentration.

Abstrak. Daerah pesisir Sabu Raijua memiliki potensi yang signifikan untuk pengembangan budidaya rumput laut. Selain memiliki kondisi oseanografi yang menguntungkan, masyarakat setempat memiliki pengetahuan lokal yang cukup untuk pemanfaatan sumber daya laut secara berkelanjutan. Potensi ini dapat ditingkatkan lebih lanjut melalui strategi adaptif yang sesuai dengan kondisi lingkungan, seperti memilih strain rumput laut yang toleran terhadap salinitas dan mengelola periode budidaya berdasarkan musim. Studi ini bertujuan untuk menilai kesesuaian budidaya Eucheuma cottonii di wilayah pesisir Sabu Raijua, dengan penekanan pada karakteristik oseanografi. Data diperoleh melalui pengukuran lapang dan pengambilan sampel air yang dilakukan di beberapa lokasi budidaya prospektif. Parameter yang diamati meliputi kedalaman air, jenis substrat, suhu, pH, salinitas, dan oksigen terlarut (DO), yang diukur di 8 stasiun. Hasil menunjukkan bahwa perairan pesisir Sabu Raijua sesuai untuk budidaya rumput laut jenis Eucheuma cottonii. Namun, stasiun II dan VIII diidentifikasi kurang sesuai karena kedalamannya yang dangkal dan konsentrasi oksigen terlarut yang rendah.
