Budidaya Udang Vaname Litopenaeus vannamei dengan Aplikasi Kapur Pertanian dan Probiotik di PT. Bumi Subur 01, Banyuwangi, Jawa Timur.

Abstract

Udang vaname merupakan komoditas budidaya bernilai ekonomi tinggi dan umumnya dibudidayakan secara intensif. Salah satu kendala utama dalam sistem intensif adalah penurunan kualitas air. Proyek akhir ini bertujuan untuk mengikuti, memahami, dan mengevaluasi kegiatan budidaya intensif serta mengkaji inovasi penambahan larutan kapur dan probiotik terhadap kualitas air dan produktivitas. Budidaya dilakukan selama 75 hari pada dua petak, yaitu D8 (perlakuan kapur) dan D9 (perlakuan penambahan kapur pertanian dan probiotik). Parameter yang diamati meliputi kualitas air (suhu, kecerahan, pH, DO, salinitas, warna air, alkalinitas, amonia, amonium, nitrit, fosfat, TVC, dan kepadatan plankton), pertumbuhan udang (LPH, LPS, sintasan), RKP, dan perubahan jumlah kincir. Hasil menunjukkan petak D8 memiliki produktivitas lebih baik dibanding petak D9. Penurunan performa di petak D9 disebabkan oleh infeksi WFD dan dominansi Cyanophyta yang berkaitan dengan penurunan kualitas air akibat cuaca tidak stabil dan perlakuan yang diberikan. Penambahan kapur pertanian dan probiotik pada larutan kapur tidak efektif meningkatkan kualitas air dan produktivitas sehingga perlu evalusi terhadap dosis, durasi, dan frekuensi pemberian.

Pacific whiteleg shrimp is a high-value aquaculture commodity that is generally cultivated intensively. One of the main challenges in intensive systems is the decline in water quality. This final project aimed to monitor, understand, and evaluate intensive farming activities, as well as examine the innovation of adding lime solution and probiotics to water quality and productivity. The cultivation was carried out for 75 days in pond D8 (lime treatments) and pond D9 (agricultural lime and probiotic treatments). The observed parameters included water quality (temperature, brightness, pH, DO, salinity, water color, alkalinity, ammonia, ammonium, nitrite, phosphate, TVC, and plankton density), shrimp growth (LPH, LPS, survival rate), RKP, and changes in paddlewheel usage. The results showed that pond D8 had better growth and RKP than pond D9. The performance decline in pond D9 was caused by WFD infection and Cyanophyta dominance, which were related to deteriorating water quality due to unstable weather and the applied treatments. The addition of probiotics and lime was not effective in improving water quality and productivity, suggesting the need for re-evaluation of dosage, duration, and frequency of application.
