N2  - Pacific white shrimp (Litopenaeus vannamei) is a excellent fishery commodity
that has great potential due to high market demand. Alginate Sargassum sp. supplementation
and vitamin C have been proven to be effective in increasing the
body resistance of Pacific white shrimp infected with the WSSV virus in laboratory
scale tests. The study aimed to examine the effectivity of Na alginate
Sargassum sp. and vitamin C in feed on the growth performance and water quality
of Pacific white shrimp in HDPE plastic ponds. The study was conducted with
two treatments: P1, commercial feed without any additives (0 ml Na alginate
Sargassum sp. + 0 g vitamin C) and P2, commercial feed with the addition of Na
alginate Sargassum sp. 100 ml per kg of feed and vitamin C 3 g per kg of feed.
The study used ponds with an area of 2,000 m2 with a stocking density of 100 fish
per m2 during the 63 day of culture. The parameters of the study included, average
body weight (ABW), average daily growth (ADG), survival rate (SR), feed conversion
ratio (FCR), and productivity, as well as water quality including, temperature,
DO, salinity, pH, phosphate, calcium, magnesium, alkalinity, brightness, and
hardness. The results showed that in P1, the productivity achieved was 15.56 kg
per mē, ABW 13.1 g per individual, ADG 0.44 g per day, SR 81.9%, and FCR
1.46. Meanwhile, in P2, the productivity achieved was 16.30 kg per mē, ABW
13.2 g per individual, ADG 0.43 g per day, SR 89.1%, and FCR 1.42. The water
quality parameter values for P1 and P2 during the maintenance period were within
the acceptable range for Pacific white shrimp cultivation. The feeding of
Sargassum sp. alginate supplementation and vitamin C could be applied in the
Pacific white shrimp farming in HDPE pond scale.

Udang vaname (Litopenaeus vannamei) merupakan komoditas perikanan unggulan
yang sangat potensial karena permintaan pasar yang tinggi. Suplementasi alginat
Sargassum sp. dan vitamin C terbukti efektif dalam meningkatkan ketahanan
tubuh udang vaname yang terinfeksi virus WSSV pada uji skala laboratorium. Penelitian
ini bertujuan untuk mengkaji efektivitas suplementasi Na alginat Sargassum
sp. dan vitamin C dalam pakan terhadap performa pertumbuhan dan kualitas
air udang vaname pada tambak plastik HDPE. Penelitian dilakukan dengan dua
perlakuan yaitu P1 pemberian pakan komersial tanpa penambahan apapun (0 ml
Na alginat Sargassum sp. + 0 g vitamin C ) dan P2 pemberian pakan komersial
dengan penambahan Na alginat Sargassum sp. 100 ml per kg pakan dan vitamin C
3 g per kg pakan. Penelitian dilakukan di tambak dengan luas 2.000 m2 dengan
padat tebar 100 ekor per m2 selama masa pemeliharaan 63 hari. Parameter penelitian
meliputi, rerata berat tubuh (ABW), rerata pertumbuhan harian (ADG), kelulusan
hidup (SR), ratio konversi pakan (FCR), dan produktivitas, serta kualitas
air meliputi, suhu, DO, salinitas, pH, fosfat, kalsium, magnesium, alkalinitas, kecerahan,
dan kesadahan. Hasil penelitian menunjukkan pada P1 menghasilkan
produktifitas sebesar 15,56 kg per m2, ABW 13,1 g per ekor, ADG 0,44 g per
hari, SR 81,9 %, dan FCR 1,46. Sedangkan pada P2 menghasilkan produktifitas
sebesar 16,30 kg per m2, ABW 13,2 g per ekor, ADG 0,43 g per hari, SR
89,1%, dan FCR 1,42. Nilai parameter kualitas air pada P1 dan P2 selama pemeliharaan
berada pada kisaran yang layak untuk budi daya udang vaname. Pemberian
pakan dengan suplementasi alginat Sargassum sp. dan vitamin C dapat
diaplikasikan pada budi daya udang vaname di tambak HDPE skala lapang.
