Dalam penerapannya, terdapat dua sistem dalam aplikasi biofloc yaitu green water system (di luar ruangan dan terkena mata -hari) dan brown water system (di dalam ruangan dan tidak terkena matahari). Pe- nelitian ini bertujuan untuk membandingkanantara green water system dan brown water systembioflocterhadap performa dan produktivitas budidaya udang vaname pada skala laboratorium. Penelitian ini dilakukan pada bulan Maret-April 2021 di Laboratorium Budidaya Perikanan, Fakultas Pertanian, Universitas Lampung. Rancangan percobaan terdiri dari 3 perlakuan yaitu masing-masing3 ulangan. Se- tiap ulangan ditebar70 benur (PL-10) per akuarium dengan ukuran 0,8-1 cm. Udang dipelihara selama 30 hari. Sampling dilakukan pada awal dan akhir pe- meliharaan dengan menimbang berat tubuh benur. Parameter yang diamati yaitu pertumbuhan berat mutlak, Spesific Growth Rate (SGR), Feed Convertion Ratio (FCR), dan kelangsungan hidup (SR). Hasil penelitian menunjukkan bahwa per- lakuan green water system secarasignifikan (P< 0,05) menghasilkan nilai per- tumbuhan berat mutlak, pertumbuhan spesifik, dan rasio konversi pakan udang vaname yaitu0,30±0,01g, 15,56±0,72%/hari, dan 0,61±0,03 secara berturut-turut. Penelitian ini dapat dijadikan acuan oleh pembudidaya untuk menerapkan green water system. Kata kunci : Biofloc, brown water system, green water system, vanamei Biofloc technology is one solution in increasing the productivity of vaname shrimp (Litopenaeus vannamei). In its application, there are two systems in bio- floc applications, namely green water system (outdoors and exposed to the sun) and brown water system (indoors and not exposed to the sun). This study aimed to compare the green water system and brown water system biofloc to the perfor- mance and productivity of vaname shrimp cultivation on a laboratory scale. This research was conducted in March-April 2021 at the Aquaculture Laboratory, Faculty of Agriculture, Lampung University. The experimental design consisted of 3 treatments, each of which is 3 repeats. Each repeat are stocked 70 vaname seeds (PL-10) by aquarium with a size of 0.8-1 cm. Shrimp were kept for 30 days. Sampling was carried out at the beginning and end of maintenance by weighing the body weight of the fry. Parameters observed were absolute weight growth, specific growth rate (SGR), feed conversion ratio (FCR), and survival rate (SR). The results showed that the treatment of green water system was significantly (P < 0.05) obtained weight growth, specific growth, and conversion rates of vaname shrimp feed of 0.30±0.01g, 15.56± 0,72%/day, and 0.61±0.03 consecutively. This research could be used as a reference by cultivators to apply green water system. .
