Berbagai Jenis Biofilter Terhadap Kualitas Air Dan Pertumbuhan Ikan Mas (Cyprinus carpio) Dalam Sistem Resirkulasi Dicky Harwanto dan Tristiana Yuniarti)

Ikan mas (Cyprinus carpio) merupakan ikan yang populer bagi masyarakat Indonesia untuk dikonsumsi. Salah satu faktor yang menjadi kendala pada budidaya ikan adalah kualitas air. Sehingga, diperlukan biofilter untuk menjaga kualitas air media budidaya. Tujuan penelitian ini untuk mengetahui pengaruh penggunaan biofilter yang berbeda pada media pemeliharaan ikan mas terhadap kualitas air, pertumbuhan dan kelulushidupan dengan sistem resirkulasi dan mengetahui jenis biofilter terbaik dari penggunaan 3 jenis biofilter yang berbeda dengan sistem resirkulasi pada media pemeliharaan ikan mas terhadap kelangsungan hidup dan penurunan konsentrasi Total Ammonia Nitrogen (TAN). Ikan mas (C. carpio) yang digunakan dalam penelitian memiliki bobot rata-rata 1,84±0,15g dan panjang rata-rata 6,36±0,14cm dengan kepadatan 15 ekor/ 30 L atau 0,92 ± 0,07 g/L. Penelitian ini menggunakan metode eksperimen, rancangan
acak lengkap (RAL) yang terdiri atas 4 perlakuan dan 3 kali ulangan. Perlakuan yang diterapkan adalah perlakuan FB (bioball), FK (kaldness), FTB (tutup botol plastik), dan TF (tanpa biofilter) dengan filter mekanik (pasir). Penelitian ini dilaksanakan di Balai Pembenihan Ikan Sawangan, Magelang, Jawa Tengah pada bulan November 2021-Januari 2022. Pemberian pakan dilakukan dengan feeding rate 3% dari biomassa ikan dengan pelet komersil dan pengamatan kualitas air dilakukan 3 kali sehari (08.00, 12.00, dan 16.00 WIB). Parameter yang diamati yaitu kualitas air, Survival Rate (SR), Specific Growth Rate (SGR), Pertumbuhan Bobot Mutlak, Total Konsumsi Pakan (TKP) dan Feed Convertion Ratio (FCR). Hasil penelitian menunjukkan bahwa perbedaan biofilter berpengaruh nyata (P<0,05) terhadap Survival Rate (SR), Specific Growth Rate (SGR), Pertumbuhan Bobot Mutlak, dan Feed Convertion Ratio (FCR) namun tidak berpengaruh nyata terhadap Total Konsumsi Pakan (TKP). Perlakuan terbaik yaitu perlakuan FB yang mana memiliki hasil suhu 22,9-27o C, pH 6,98-8,59, DO 5,1-6,9 mg/L, TAN
0,01±0,00-0,15±0,01 mg/L, efisiensi penurunan konsentrasi TAN 17,9±17,48%, Volumetric TAN Removal (VTR) 3,89±4,1 g/m
3/d, Survival Rate (SR) 95,56±3,85%, Specific Growth Rate (SGR) 2,15±0,16%, Pertumbuhan Bobot Mutlak 3,03±0,10g, Total Konsumsi Pakan (TKP) 85,83±4,73 g dan Feed Convertion Ratio (FCR) 1,89±0,15%.

ABSTRACT
(Mh. Yusuf Rohul Islam. 26020117130075. Effect of the use various
types biofilters on water quality and growth carp (Cyprinus carpio) in a recirculation system Dicky Harwanto and Tristiana Yuniarti)
Common carp (Cyprinus carpio) is a popular fish for Indonesian people to consume. One of the factors that become obstacles in fish farming is water quality. Thus, a biofilter is needed to maintain the water quality of the cultivation media. The purpose of this study was to determine the effect of using different biofilters in carp rearing media on water quality, growth and survival with a
recirculating system and to find out the best type of biofilter using 3 different types of biofilter with a recirculating system in carp rearing media on survival and decline. concentration of Total Ammonia Nitrogen (TAN). Goldfish (C. carpio) used in the study had an average weight of 1.84 ± 0.15 g and an average length of 6.36 ± 0.14 cm with a density of 15 fish/30 L or 0.92 ± 0.07 g/l. This
study used an experimental method, a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatments applied were FB (bioball), FK (kaldness), FTB (plastic bottle cap), and TF (without biofilter) with a mechanical filter (sand). This research was conducted at the Sawangan Fish
Hatchery Center, Magelang, Central Java in November 2021-January 2022. Feeding was carried out at a 3% feeding rate of fish biomass with commercial pellets and water quality observations were carried out 3 times a day (08.00, 12.00 and 16.00 WIB). Parameters observed were water quality, Survival Rate (SR), Specific Growth Rate (SGR), Absolute Weight Growth, Total Feed
Consumption (TKP) and Feed Conversion Ratio (FCR). The results showed that differences in biofilters had a significant effect (P<0.05) on Survival Rate (SR), Specific Growth Rate (SGR), Absolute Weight Growth, and Feed Conversion Ratio (FCR) but had no significant effect on Total Feed Consumption (TKP). ). The best treatment was the FB treatment which had a temperature of 22.9-27oC, pH 6.98-8.59, DO 5.1-6.9 mg/L, TAN 0.01±0.00-0.15± 0.01 mg/L, TAN concentration reduction efficiency 17.9±17.48%, Volumetric TAN Removal (VTR) 3.89±4.1 g/m3/d, Survival Rate (SR) 95.56±3, 85%, Specific Growth Rate (SGR) 2.15±0.16%, Absolute Weight Growth 3.03±0.10g, Total Feed Consumption (TKP) 85.83±4.73 g and Feed Conversion Ratio (FCR) 1.89±0.15%.
