Abstract

Ubi jalar memiliki kandungan karbohidrat yang cukup tinggi, vitamin A dan C serta mineral. Selain mengandung zat gizi yang dibutuhkan, ubi jalar juga mengandung zat tripsin  inhibitor yang dapat dihilangkan melalui pemanasan.  Tujuan penelitian ini adalah untuk mengetahui sintasan dan pertumbuhan ikan koi yang diberi pakan mengandung tepung ubi jalar yang telah diolah dan tanpa diolah serta pakan tanpa ubi jalar. Ikan uji sebanyak 8 ekor dimasukkan ke dalam setiap wadah penelitian ( akuarium 50 x 40 x 40 cm3)  yang berisi air tawar  sekitar 60%  dari volume total wadah (± 64 liter). Pemberian pakan dilakukan 3 kali sehari  sebanyak 5% per bobot biomassa ikan uji.  Parameter yang diamati adalah sintasan, pertumbuhan bobot dan pertumbuhan panjang.   Hasil yang diperoleh menunjukkan pakan yang megandung tepung ubi jalar yang telah diolah dan tanpa diolah memberikan pertambahan panjang dan sintasan ikan koi yang tidak berbeda namun pada pertumbuhan bobot berbeda.  Pakan yang mengandung tepung ubi jalar dan tanpa ubi jalar juga memperlihatkan hasil yang sama pada semua perlakuan.

Abstract

Water quality parameters in pond include ammonia, nitrite, nitrate, phosphate, BOD, DO, turbidity, temperature, and pH. It is important to know the concentration of each component to properly minimize the negative impacts of their disturbances for the overall water quality and the biota in it. This study aims to determine the concentration of ammonia, nitrite, nitrate, phosphate, BOD, DO, turbidity, temperature, and pH in freshwater fish ponds at the Central Fish Seed Office (BBIS) of Masni, Manokwari Regency, West Papua Province. The study was conducted in May 2017, representing the rainy season, and August 2017, representing the dry season. Water samples were taken from settling, rearing, hatchery, and brood ponds. Meanwhile, standard method was implemented in the component measurements. The study results show that the concentrations of ammonia, nitrite, nitrate, and phosphate were 0.02-0.18 mg/L, 0.00-2.00 mg/L, 0.40-1.00 mg/L, and 1.01-21.83 mg/L, respectively. Furthermore, the concentrations of BOD and DO were 6.12-8.19 mg/L and 7.30-12.00 mg/L, respectively. Finally, the values of turbidity, temperature, and pH were 0.40-9.99 NTU, 26-30°C and 7.7-8.5, respectively.
