Abstract
Study on white shrimp (Litopenaeus vannamei) production in biocrete pond in different density was performed at PT. Bimasena Segara, Citarate, Sukabumi, West Java. Six ponds were used and devided into 2 groups based the density levels, i.e., 72-73 shrimp/m2 and 93-105 shrimp/m2. Experiment was done for 100 days, including pond preparation. The results of study showed that mean weight of shrimp reared in biocrete pond was ranged from 9.64 to 12.34 gram, survival rate 26.97-99.58%, productivity 3,078-8,340.9 kg/ha, feed quantity 2,084.5-2,870.4 kg and FCR 1.19-2.60. Ponds with lower rearing density had lower (P<0.1) productivity, mean weight, survival and FCR compared to those of higher rearing density.

ABSTRAK
Penelitian mengenai produksi udang vaname (Litopenaeus vannamei) di tambak biocrete dengan padat penebaran berbeda telah dilakukan di tambak PT. Bimasena Segara, Citarate, Sukabumi, Jawa Barat menggunakan 6 petak tambak yang dibedakan menjadi 2 kelompok berdasarkan padat tebar udang yang selanjutnya menjadi perlakuan, yaitu : 72-73 ekor/m2 dan 93-105 ekor/m2. Penelitian ini dilakukan selama 100 hari termasuk persiapan tambak. Hasil penelitian menunjukkan abhwa bobot rata-rata udang yang dipelihara di tambak biocrete berkisar antara 9,64-12,34 g, kelangsungan hidup berkisar antara 26,97-99,58%, produktivitas berkisar antara 3078,7-8340,9 kg/ha, jumlah pakan yang diberikan berkisar antara 2084,5-2870,4 kg dan FCR berkisar antara 1,19-2,60. Petak dengan kepadatan rendah memiliki nilai produktivitas, bobot rata-rata, kelangsungan hidup dan konversi pakan (FCR) berbeda nyata (P < 0,1) dan lebih baik dibanding dengan yang berkepadatan tinggi.
