Abstract

Budidaya udang vannamei merupakan salah satu kegiatan alternatif yang bergerak dalam bidang budidaya perikanan. Kegiatan ini dilaksanakan mulai dari tanggal 10 Maret-16 Juni di PT. Bumi Harapan Jaya di desa Tambak Sari Kecamatan Poto Tano. Kegiatan ini bertujuan untuk mengetahui optimalisasi tambak udang di PT. Bumi Harapan Jaya dalam meningkatkan ekonomi masyarakat di desa Tambak Sari, Poto Tano. Perusahaan PT. Bumi Harapan Jaya ini didirikan pada tahun 2009 yang bergerak di bidang budidaya perikanan khususnya usaha tambak udang. Kegiatan budidaya yang dilakukan termasuk dalam sistem intensif dimana padat tebar serta jumlah pakan yang diberikan secara intensif. Metode yang digunakan adalah metode kuantitatif Berdasarkan kegiatan yang dilakukan menunjukkan bahwa pendapatan masyarakat sekitar tambak yang berprofesi sebagai pedagang Rp. 950.000/bulan dan Nelayan Rp.850.000/bulan. Sedangkan pendapatan masyarakat setelah adanya usaha tambak udang pedagang mencapai Rp1.500.000 per bulan dan Nelayan yang bekerja sebagai pekerja tambak mencapai Rp2.400.000 per bulan.

Abstract

Feed is a very important factor because it takes up 60-70% of the total operational costs, so that feed provided according to needs will stimulate optimal growth and development of shrimp production. The use of auto feeder machines can help in providing shrimp feed more effectively and maintaining water quality to remain stable and suitable for vannamei shrimp cultivation. The purpose of this study was to determine the efficiency of feeding in vannamei shrimp ( Litopenaeus vannamei ) cultivation . The method used in this study is the method descriptive, the data analyzed in this study is shrimp growth data obtained from sampling results and water quality data both in the field and laboratory. The results of this study are that the daily growth (ADG) of vannamei shrimp is in the range of 0.22-0.38 grams, this data is already optimal and for the average weight (MBW) obtained 4.56 grams then increased over time to reach DOC 108 with a weight of 24.97 grams. Based on the results of the average weight growth obtained, it is known that the growth is optimal and it is known that the water quality value is still in optimal condition in vannamei shrimp cultivation, both physical and chemical parameters. From this study it is known that feeding using an auto feeder has a good effect on the growth of ADG and MBW shrimp and also the feed given using an auto feeder can minimize feed falling to the bottom so that water quality is maintained and remains in optimal condition for vannamei shrimp cultivation.

Abstract

Vaname shrimp is one of the marine fishery commodities that has high economic value. Water in vaname shrimp cultivation must be maintained in quality. Ammonia can be harmful to shrimp, control of ammonia and organic matter content can be done biologically with the application of probiotics. Therefore, this study needs to be conducted to determine the right time interval in providing probiotics to the water quality of vaname shrimp cultivation in the biofloc system. The method used in this study is the experimental method, using RAL with 4 treatment levels and 3 repetitions, with treatment P0 (Once during maintenance), P1 (once every 5 days), P2 (once every 10 days) and P3 (once every 15 days), the probiotic used in this study is the probiotic Probio-7. The results of the study during 56 days of maintenance showed that the average value of water quality salinity 26.7-27 ppt, temperature 27.7-28°C DO 7.13-7.16 mg/L, nitrate 0.63-0.87 mg/L and Total Ammonia 0.76-0.92 mg/L. Based on the research activities that have been carried out, the interval of probiotic administration has a significant effect on water quality. Probiotic administration can increase the Total Ammonia content and reduce the amount of ammonia in this study. Probiotic administration with an interval of 5 days once (P1) gave a total ammonia value of 0.78 mg/L with an ammonia amount of 0.067 mg/L. P1 also gave the highest growth, absolute weight 5.61 g, absolute length 8.82 cm, SGR 5.779%/Day and FCR 1.47.
