Penelitian ini bertujuan untuk mengetahui sebaran dan tutupan Ulva lactuca serta kualitas air di Perairan Teluk Benoa, Bali. Metode yang digunakan dalam penelitian ini adalah deskriptif kuantitatif menggunakan teknik simple random sampling pada lima stasiun. Hasil sebaran Ulva lactuca pada lima stasiun berdasarkan perhitungan Indeks Morisita (Id) menunjukkan kategori seragam ( uniform ) dengan seluruh nilai < 1. Tutupan Ulva lactuva pada stasiun 1, 2, dan 5 tergolong sedang dengan nilai berturut-turut sebesar 33,69%, 32,62%, dan 34,58%. Stasiun 4 termasuk dalam kategori sangat padat dengan tutupan sebesar 91,96%, sedangkan stasiun 3 berada pada kategori padat dengan tutupan sebesar 55,52%. Hasil pengukuran kualitas air menunjukkan nilai dengan rata-rata parameter suhu sebesar 30°C, pH 7, salinitas 31 ppt, kecepatan arus sebesar 0,085 m/s, kecerahan 1,1 meter, serta konsentrasi nitrat sebesar 0,369 mg/L dan fosfat 0,224 mg/L. Hasil penelitian menunjukkan rata-rata sebaran dan tutupan Ulva lactuca berada pada kategori sebaran seragam dan tutupan pada kategori sedang.

Pola sebaran Ulva lactuca yang relatif luas di seluruh stasiun pengamatan mengindikasikan potensi ketersediaan biomassa yang dapat dimanfaatkan sebagai sumber bahan pangan berbasis makroalga. Ulva lactuca is a potential biological resource for alternative food raw materials in the waters of Benoa Bay, Bali. No studies have been conducted to date on stock availability through calculations of the distribution and coverage of Ulva lactuca. This study aims to determine the distribution and coverage of Ulva lactuca as well as water quality in the waters of Benoa Bay, Bali. The method used in this study was quantitative descriptive analysis employing simple random sampling at five stations. The distribution results of Ulva lactuca at the five stations, based on the Morisita Index (Id) calculation, indicated a uniform category, with all values < 1. The Ulva lactuca coverage at stations 1, 2, and 5 was classified as moderate, with values of 33.69%, 32.62%, and 34.58%, respectively. Station 4 falls into the very dense category with a coverage of 91.96%, while Station 3 is in the dense category with a coverage of 55.52%. Water quality measurements showed average values for temperature at 30°C, pH 7, salinity 31 ppt, current velocity 0.085 m/s, turbidity 1.1 meters, as well as nitrate concentration at 0.369 mg/L and phosphate at 0.224 mg/L. The research results indicate that the average distribution and coverage of Ulva lactuca fall into the uniform distribution category and the moderate coverage category, respectively. The water conditions in Benoa Bay indicate water quality that is generally optimal for the distribution of Ulva lactuca. The relatively widespread distribution of Ulva lactuca across all observation stations indicates the potential availability of biomass that can be utilized as a source of macroalgae-based food. }, issn = {2407-7690}, pages = {272--282} doi = {10.14710/jmr.v15i2.49244}, url = {https://ejournal3.undip.ac.id/index.php/jmr/article/view/49244} }
