Ababila, Sholeli Unka and Dr. Ir. Abd. Rahem Faqih, M.Si. and Ayu Winna Ramadhani, S.Pi., M.Si. (2025) Analisis Kadar Hematokrit Ikan Nila (Oreochromis niloticus) pada Sistem Budidaya Bioflok dan Non Bioflok sebagai Indikator Kesehatan. Sarjana thesis, Universitas Brawijaya.
Abstract
Ikan Nila (Oreochromis niloticus) merupakan salah satu komoditas penting dalam perikanan air tawar di Indonesia, dikenal karena kemampuannya beradaptasi dan permintaan pasar yang tinggi. Penelitian ini berfokus pada analisis kadar hematokrit sebagai indikator kesehatan ikan nila yang dibudidayakan dalam dua sistem, yaitu bioflok dan non-bioflok. Sistem bioflok semakin populer karena kemampuannya mengubah limbah menjadi pakan alami, namun dapat menyebabkan stres pada ikan jika kualitas air tidak terjaga. Penelitian ini dilaksanakan pada bulan Oktober-November 2024 di Khawi Fish Farm dan Laboratorium Budidaya Ikan Universitas Brawijaya. Metode yang digunakan adalah deskriptif kuantitatif dengan rancangan stratified random sampling, di mana populasi dibagi berdasarkan umur (3, 4, dan 5 bulan) dan sampel diambil secara acak. Parameter utama yang diuji adalah kadar hematokrit, sementara parameter penunjang meliputi kualitas air, volume flok, morfometrik dan meristik ikan. Hasil penelitian menunjukkan kadar hematokrit ikan nila pada sistem bioflok lebih tinggi dibanding non-bioflok di semua kelompok umur, dengan perbedaan signifikan: umur 3 bulan (30% vs. 24%, p = 0,003), 4 bulan (28% vs. 25%, p < 0,01), dan 5 bulan (29,67% vs. 22%, p < 0,01). Suhu air bioflok lebih stabil (26,2–28,9°C), DO lebih rendah (5,11–7,11 ppm) namun mendukung pertumbuhan, dan pH sedikit di bawah standar (6–6,8). Volume flok menurun dari 6% (umur 3 bulan) menjadi 3% (umur 4-5 bulan) tanpa mengurangi kualitas air. Panjang ikan bioflok pada umur 5 bulan (23,26 cm) lebih besar dibanding nonbioflok (18,98 cm). Sistem bioflok terbukti lebih mendukung kesehatan dan pertumbuhan ikan.
English Abstract
Tilapia (Oreochromis niloticus) is one of the important commodities in freshwater fisheries in Indonesia, known for its adaptability and high market demand. This study focuses on the analysis of hematocrit levels as an indicator of the health of tilapia cultivated in two systems, namely biofloc and non-biofloc. Biofloc systems are growing in popularity due to their ability to convert waste into natural feed, but they can cause stress in fish if water quality is not maintained. This research was carried out in October-November 2024 at the Khawi Fish Farm and the Fish Cultivation Laboratory of Universitas Brawijaya. The method used was quantitative descriptive with a stratified random sampling design, where the population was divided by age (3, 4, and 5 months) and samples were taken randomly. The main parameters tested were hematocrit levels, while supporting parameters included water quality, floc volume, morphometrics and fish meristic. The results showed that the hematocrit levels of tilapia in the biofloc system were higher than those of non-biofloc in all age groups, with significant differences: age of 3 months (30% vs. 24%, p = 0.003), 4 months (28% vs. 25%, p < 0.01), and 5 months (29.67% vs. 22%, p < 0.01). The water temperature of biofloc is more stable (26.2–28.9°C), the DO is lower (5.11–7.11 ppm) but supports growth, and the pH is slightly below standard (6–6.8). The volume of floc decreased from 6% (3 months old) to 3% (4-5 months old) without reducing water quality. The length of biofloc fish at the age of 5 months (23.26 cm) is greater than that of non-biofloc (18.98 cm). The biofloc system has been shown to be more supportive of fish health and growth
