Pada usaha budidaya intensif, pakan mampu menyerap 60% - 70% dari total biaya produksi udang. Tujuan penelitian ini untuk mengetahui frekuensi pemberian pakan yang tepat terhadap pertumbuhan berat mutlak udang vaname (L. vannamei). Berdasarkan hasil penelitian setelah dianalisis dengan statistik, maka dapat disimpulkan bahwa pemberian frekuensi pakan yang berbeda berpengaruh nyata terhadap pertumbuhan berat mutlak udang vaname, perlakuan pemberian pakan dengan frekuensi 4x memberikan hasil tertinggi sebesar 0,38 gr/hari. Data kualitas air berturut-turut suhu air berkisar 26 – 30OC, pH 7,8 – 8,2, kandungan oksigen terlarut 4,7– 5,2 ppm, salinitas 35 - 37 ppt, amonia (NH4) 0 – 0,5 mg/L, nitrit (NO2) 0,016-0,028 mg/L, fosfat (PO4) 0 – 0,5 mg/L, dan TOM 92-103 mg/L. Namun nilai Total Organic Matter (TOM) tergolong tidak layak dalam proses budidaya udang vaname karena melebihi batas yang dapat ditoleransi oleh udang vaname yakni 55 mg/L.Kata kunci: Udang vaname, frekuensi pakan, pertumbuhan berat mutlak, kualitas airABSTRACTVaname shrimp has a fast market at the world level. Provision of high quality feed is an important factor that determines the success of shrimp farming. In intensive aquaculture, feed is able to absorb 60% - 70% of the total cost of shrimp production. The aim of this study was to determine the proper frequency of feeding on the absolute weight growth of vannamei shrimp (L. vannamei). Based on the research results after being analyzed, it can be concluded that the provision of different feeding frequencies has a significant effect on the absolute weight growth of vannamei shrimp, the treatment of feeding with a frequency of 4x gives the highest yield of 0.38 g/day. Water quality data successively water temperature ranges from 26 – 30oC, pH 7.8 – 8.2, dissolved oxygen content 4.7 – 5.2 ppm, salinity 35 – 37 ppt, ammonia (NH4) 0 – 0.5 mg/L, nitrite (NO2) 0.016-0.028 mg/L, phosphate (PO4) 0-0.5 mg/L, and TOM 92-103 mg/L. However, the Total Organic Matter (TOM) value is classified as inappropriate in the process of cultivating vannamei shrimp because it exceeds the limit that can be tolerated by vannamei shrimp, which is 55 mg/L.Keywords: Vaname shrimp, feed frequency, absolute weight growth, quality water
