Abstract

Penelitian ini bertujuan untuk mengetahui kadar alkalinitas dan kesadahan (hardness) pada pembesaran udang putih (Litopenaeus vannamei) di tiga tambak binaan PT. Central Proteina Prima, Medan. Analisa kualitas air untuk pembesaran udang dilakukan untuk mengetahui keadaaan stabilitas perairan. Upaya untuk mengetahui kualitas air pada pembesaran udang, salah satunya dengan pengukuran parameter kimia alkalinitas dan kesadahan. Analisa alkalinitas dan kesadahan ini dilakukan dengan metode volumetri (titrimetri), di Laboratorium Animal Health Service Medan. Hasil yang diperoleh dari analisa yaitu : tambak Sri Ratu alkalinitas 88 ppm dengan kesadahan 460 ppm, tambak Sutatama alkalinitas 96 ppm dengan kesadahan 350 ppm,, tambak CPF 3 alkalinitas 126 ppm dengan kesadahan 290 ppm. Kadar alkalinitas yang baik untuk pembesaran udang ialah >20 ppm dan tidak lebih dari 500 ppm. Sedangkan kadar yang baik untuk kesadahan tidak lebih dari 500 ppm. Berdasarkan hasil yang diperoleh, maka kegiatan manajemen pengelolaan kualitas air di masing-masing tambak sudah dilakukan dengan optimal.

Abstract

Snakehead has been reported to have high protein content and economic value. This study aims to determine: (1) nutritional content (proximate) fresh snakehead, (2) the results of snakehead fish protein concentrate, (3) nutritional content of snakehead fish protein concentrate, and (4) total amino acid content of fish protein concentrate snakehead. Research in five steps experiment: (1) preparation of fresh snakehead fish meat, (2) analysis of nutritional content (proximate) snakehead fish meat, (3) analysis of the results of snakehead fish protein concentrate, (4) analysis of nutrient content (proximate) concentrate snakehead fish protein, and (5) analysis of the total amino acid content of snakehead fish protein concentrate. The current study reported that the nutritional content (proximate) of fresh meat snakehead fish was 75.52% water (bb): 77.69% protein (bk); 4.18% fat (bk), 14.77% ash (bk), and 3.36% carbohydrate (bk). The average yield produced in the manufacture of snakehead fish protein concentrate was 69.87%. While the nutritional content (proximate) snakehead fish protein concentrate is 8.97% water, 66.07% protein, 0.89% fat; 11.53% ash, and 12.54% carbohydrates. The highest levels of amino acids in snakehead fish protein concentrate were lysine (6,12%) and tryptopan (5,89)
