Manajemen Produksi dan Analisis Usaha Pendederan Udang Vaname (Litopenaeus Vannamei) pada Salinitas Rendah dengan Pemberian Pakan Berbeda

Abstract

Penelitian ini bertujuan mengukur pengaruh penggunaan pakan alami berbeda terhadap kinerja produksi dan analisis usaha pendederan udang vaname pada media salinitas rendah. Penelitian dilaksanakan selama 21 hari menggunakan rancangan acak lengkap dengan tiga perlakuan, yaitu Artemia sp. + pakan komersial (A), Moina sp. + pakan komersial (M), dan kombinasi 50% Artemia sp. + 50% Moina sp. + pakan komersial (C), masing-masing lima ulangan. Parameter yang diamati meliputi kinerja produksi, kualitas air, dan analisis usaha. Hasil penelitian menunjukkan bahwa penggunaan pakan alami berbeda memberikan pengaruh nyata (P<0,05) terhadap kinerja produksi dan analisis usaha. Perlakuan A menghasilkan tingkat kelangsungan hidup tertinggi (95,56±2,16%), rasio konversi pakan terendah (1,33±0,15), produktivitas tertinggi (66,89±1,51 ekor L?¹ tahun?¹), serta keuntungan terbesar (Rp662.092) dengan nilai revenue-cost ratio (R/C) sebesar 1,09. Perlakuan C menunjukkan kinerja yang mendekati perlakuan A, sedangkan perlakuan M menghasilkan kinerja terendah. Dengan demikian, Artemia sp. merupakan pakan alami terbaik untuk meningkatkan kinerja produksi dan kelayakan usaha pendederan udang vaname pada media salinitas rendah

This study aimed to evaluate the effects of different natural feeds on the production performance and economic feasibility of Pacific white shrimp (Litopenaeus vannamei) nursery culture under low-salinity conditions. The experiment was conducted for 21 days using a completely randomized design with three treatments: Artemia sp. plus commercial feed (A), Moina sp. plus commercial feed (M), and a combination of 50% Artemia sp. and 50% Moina sp. plus commercial feed (C), each with five replicates. The observed parameters included production performance, water quality, and economic analysis. The results showed that different natural feeds significantly affected (P<0,05) production performance and economic feasibility. Treatment A produced the highest survival rate (95,56 ± 2,16%), the lowest feed conversion ratio (1.33 ± 0.15), the highest productivity (66.89 ± 1.51 individuals L?¹ year?¹), and the highest profit (IDR 662,092) with a revenue-cost ratio (R/C) of 1,09. Treatment C showed production performance and economic feasibility comparable to Treatment A, whereas Treatment M resulted in the lowest performance for most parameters. Therefore, Artemia sp. was the most effective natural feed for improving production performance and economic feasibility in the nursery culture of Pacific white shrimp under low-salinity conditions.
