Abstract
Udang Vaname (Litopenaeus vannamei) merupakan komoditas perikanan yang memiliki nilai konsumsi yang sangat tinggi di Indonesia. Hasil data produksi udang vaname di Kementerian Kelautan dan Perikanan memiliki peningkatan setiap tahunnya. Hal ini sangat berpotensi untuk memenuhi kebutuhan ekspor ke beberapa negara yang memiliki produksi udang vaname yang belum mencukupi. Pada kegiatan pembesaran udang vaname memiliki banyak tahap agar kondisi media hidup udang dalam keadaan baik. Namun, kendala yang sering dihadapi oleh pembudidaya saat pembesaran memiliki kualitas air yang kurang optimal untuk kebutuhan udang vaname. Tujuan dari penelitian ini yaitu mengetahui efektivitas parameter fisika kimia air terhadap laju pertumbuhan pada udang vaname. Hasil penelitian ini dapat menjadi acuan terhadap kegiatan budidaya untuk melakukan manajemen kualitas air yang baik. Kegiatan penelitian ini dilaksanakan disalah satu tambak percobaan daerah Situbondo, Jawa timur. Penelitian ini berlangsung mulai tanggal 28 Oktober 2021 sampai dengan 14 Desember 2021. Metode yang digunakan adalah metode deskriptif kuantitatif berdasarkan penentuan kolam sebagai sampling penelitian, pengukuran parameter kualitas air, dan pengukuran berat udang. Metode ini merupakan metode yang berdasarkan pengumpulan data secara Real Time pada lapang sehingga mendapatkan hasil lalu menganalisa data tersebut beserta hasilnya lalu dibandingkan dengan data sekunder yang didapatkan dari literatur. Hasil pengukuran parameter kualitas air di tambak percobaan daerah Situbondo Jawa Timur memiliku suhu dengan rentang 29-34ºC, salinitas sekitar 24-37 ppt, pH sekitas 8,3-9,2, TOM sekitar 73-212 mg/l, kecerahan sekitar 15-95 cm, dan alkalinitas sekitar 116-220 mg/l. Berdasarkan hasil tersebut dihitung dari hasil perhitungan Mean Body Weight (MBW) yang diperoleh dari DOC 37 dan 44 pada kolam B1 sebesar 4,35 gr/ekor dan 5,9 gr/ekor, B2 sebesar 4,48 gr/ekor dan 5,4 gr/ekor, B3 sebesar 4,81 gr/ekor dan 6 gr/ekor, dan pada kolam B4 sebesar 4,21 gr/ekor dan 5,8 gr/ekor. Sedangkan hasil perhitungan Average Daily Growth (ADG) keseluruhan adalah sebesar 0,7 gr/hari. Nilai ADG terendah terdapat pada kolam B2 yaitu sebesar 0,13 gr/hari, sedangkan nilai ADG tertinggi terdapat pada kolam B1 dan B4 yaitu sebesar 0,22 gr/hari selama periode kultur 49 hari. Berdasarkan hasil perhitungan keseluruhan dapat disimpulkan bahwa kolam B2 termasuk kategori kurang optimal, sedangkan kolam B1, B3 dan B4 termasuk dalam kategori optimal.
English Abstract
Vaname Shrimp (Litopenaeus vannamei) is a fishery commodity that has a very high consumption value in Indonesia. The results of vaname shrimp production data at the Ministry of Maritime Affairs and Fisheries have increased every year. This has the potential to meet the needs of exports to several countries that have insufficient vaname shrimp production. In vaname shrimp rearing activities, there are many stages so that the conditions of the shrimp live media are in good condition. However, the obstacle that is often faced by cultivators when rearing is that the water quality is less than optimal for the needs of vaname shrimp. The purpose of this study was to determine the effectiveness of the water physicochemical parameters on the growth rate of vaname shrimp. The results of this study can be used as a reference for aquaculture activities to carry out good water quality management. This research activity was carried out in one of the experimental ponds in the Situbondo area, East Java. This research took place from October 28, 2021, to December 14, 2021. The method used is a descriptive quantitative method based on the determination of the pond as research sampling, measurement of water quality parameters, and measurement of shrimp weight. This method is a method based on real-time data collection in the field to get the results and then analyze the data and the results and then compare them with secondary data obtained from the literature. The results of the measurement of water quality parameters in experimental ponds in the Situbondo area, East Java, have a temperature in the range of 29-34ºC, salinity around 24-37 ppt, pH around 8.3-9.2, TOM around 73- 212 mg/l, brightness around 15- 95 cm, and the alkalinity is about 116-220 mg/l. Based on these results, it is calculated from the results of the calculation of the Mean Body Weight (MBW) obtained from DOC 37 and 44 in ponds B1 of 4.35 g / head and 5.9 g / head, B2 of 4.48 g / head, and 5.4 g/head, B3 is 4.81 g/head and 6 g/head, and in the pond, B4 is 4.21 g/head and 5.8 gr/head, while the overall Average Daily Growth (ADG) is 0,7 g/day. The lowest ADG value was found in pond B2, which was 0.13 g/day, while the highest ADG value was found in ponds B1 and B4, which was 0.22 g/day during the 49-day culture period. Based on the results of the overall calculation, it can be concluded that pool B2 is included in the lessthan optimal category, while pools B1, B3, and B4 are included in the optimal category.
