Abstract
Preferensi cacing kacang (Antillesoma sp.) terkonsentrasi pada zona intertidal yang berdampak dengan adanya tekanan ekologi di Sulawesi Tenggara. Penelitian ini bertujuan untuk mengetahui preferensi habitat cacing kacang di Pantai Toronipa dan Bokori Kabupaten Konawe Sulawesi Tenggara. Penelitian ini dilaksanakan selama tiga bulan yaitu pada bulan Agustus sampai Oktober 2023. Sampel diambil secara acak menggunakan transek kuadrat ukuran 1x1 m². Data dianalisis menggunakan rumus baku dan olahan data program Multi Variate Statistical Package (MVSP). Jumlah sampel yang diperoleh selama penelitian sebanyak 414 individu. Hasil analisis nilai kepadatan cacing kacang yaitu 3-12 ind/m². Pola distribusi menunjukkan cacing kacang menyebar secara mengelompok berkisar 4.9-5.8. Hasil pengukuran parameter lingkungan meliputi suhu, salinitas, pH, bahan organik dengan masing-masing 28-34°C, 6.7–7.6, 1.49-4.92 mg/l. Tekstur substrat didominasi oleh pasir halus dan lumpur. Preferensi habitat menunjukkan tekstur substrat mempunyai kontribusi besar dan menjadi penciri di setiap stasiun. Nilai tersebut menunjukkan cacing kacang perairan Pantai Toronipa dan Desa Bokori menyenangi tekstur substrat pasir halus dan pasir sangat halus.
