Abstract

Vaname is one type of shrimp that is often cultivated in Indonesia. The shrimp farming system model consists of an extensive system (traditional) and an intensive system. This study aims to compare the abundance of plankton, water conditions, growth performance of vannamei shrimp (Litopenaeus vannamei) in intensive and extensive aquaculture systems in the waters of Banyuwangi Regency. Parameters measured include physical and chemical parameters, namely temperature, brightness, pH, dissolved oxygen, salinity, ammonia, and alkalinity, type and abundance of plankton. The research method used is descriptive method. The method of analysis is the abundance of plankton, and analysis of productivity, SR, FCR and growth of vannamei shrimp. The results showed that plankton in intensive pond waters were identified as many as 4 classes, namely phytoplankton class Chlorophyta, Cyanophyta and Chrysophyta, while zooplankton class Protozoa. In traditional ponds, it is not much different, only the Crpytophyta class as an additional identification result. The abundance of plankton in intensive ponds reaches 27,595 individuals per liter, while for extensive ponds the abundance of plankton reaches 37,641 individuals per liter. While the survival rate of shrimp in intensive ponds is around 86%, while in extensive ponds is 67%. The FCR value for extensive ponds is 1.02, while the FCR value for intensive ponds is 1.17. The final average weight of shrimp in intensive ponds was 11.76 g/head and 8.33 g/head in extensive ponds.Keyword : Vaname Shrimp, Intensive Cultivation, Extensive

Abstract

Masalah utama pada budidaya  udang secara intensif adalah menurunnya kualitas air yang layak selama pemeliharaan udang dan munculnya penyakit. Masalah ini mengakibatkan  menurunya produktifitas udang vaname. Salah satu upaya yang dilakukan adalah melalui penerapan metode pengelolaan lumpur, dengan tujuan untuk mengurangi tumpukan lumpur didasar tambak intensif. Metode pengelolaan lumpur antara lain sistem, CRS (Close Resirculating System), semi close dan bioflok. Metode penulisan yang digunakan yaitu studi pustaka, untuk analisis data dengan membandingkan rata rata data produksi dan kualitas air pada masing masing sistem. Pengelolaan lumpur pada sistem CRS, memindahkan sisa bahan organik kedalam kolam pengendapan. Pada sistem semi close, membuang lumpur secara berkala melalui central draine. Pengelolaan lumpur pada sistem bioflok, memanfaatkan bakteri heterotopik untuk mengolah sisa bahan organik. Average Daily Gain (ADG) terbesar terdapat pada sistem bioflok sebesar 0.16 g/day dan terkecil pada sistem semi close sebesar 0,11 gr/day. Survival rate (SR) tingkat kelulus hidupan tertinggi pada sistem bioflok dengan SR mencapai 88%, dan terendah pada sistem CRS yaitu 81%. Feed Convertion Ratio (FCR) terbaik pada sistem bioflok yaitu nilai FCR mencapai 1.26, berikutnya sistem CRS dengan FCR 1.33, dan pada sistem semi close nilai FCR mencapai 1.93. Sistem pengelolaan lumpur terbaik  dari ketiga sistem tersebut yaitu sistem bioflok. Rata-rata data kualitas air harian dari ketiga sistem tersebut masih dalam kondisi optimal, walaupun pada parameter amonia, nitrit, dan nitrat terpaut tinggi, namun pada tingkat kelulus hidupan udang ketiga sistem tersebut masih diatas 80%.
