Penelitian ini bertujuan untuk mengevaluasi pengaruh penggunaan tanaman air berbeda terhadap pertumbuhan ikan lele dumbo (clarias gariepinus) dalam sistem akuaponik. tanaman air yang digunakan meliputi kangkung (ipomoea aquatica f.), sawi (brassica rapa l.), dan kombinasi keduanya. pertumbuhan ikan diamati melalui panjang mutlak, berat mutlak, laju pertumbuhan spesifik (sgr), dan tingkat kelangsungan hidup (sr) selama periode penelitian. hasil penelitian menunjukkan bahwa penggunaan kangkung sebagai media biofilter menghasilkan pertumbuhan tertinggi, dengan panjang mutlak rata-rata 8,44 cm dan berat mutlak rata-rata 15,46 gram. sgr mencapai 8,48%. sawi juga memberikan hasil yang baik, dengan panjang mutlak rata-rata 6,08 cm, berat mutlak rata-rata 9,69 gram, dan sgr 7,26%. kombinasi kangkung dan sawi menghasilkan pertumbuhan yang lebih rendah dibandingkan dengan penggunaan kangkung tunggal, namun masih lebih baik daripada kontrol. penggunaan kontrol tanpa media biofilter tanaman air memberikan hasil yang paling rendah. kesimpulannya, penggunaan kangkung sebagai media biofilter dalam budidaya akuaponik dapat meningkatkan pertumbuhan bibit ikan lele dumbo secara signifikan. kata kunci: filter, kualitas air, growth rate, survivel rate

The objective of the research was to evaluate the effect of using different aquatic plants on the growth of dumbo catfish (clarias gariepinus) in an aquaponic system. the aquatic plants used were kale (ipomoea aquatica f.), mustard greens (brassica rapa l.), and a combination of both. the growth of the fish was observed by the absolute length, the absolute weight, the spesific growth rate (sgr) and the survival rate (sr) during the research period. the results of the research showed that the use of kale as biofilter media resulted in the highest growth with an average absolute length of 8.44 cm and an average absolute weight of 15.46 grams. the sgr reached 8.48%. mustard also gave good results with an average absolute length of 6.08cm, an average absolute weight of 9.69 grams and an sgr 7.26%. the combination of kale and mustard produced lower growth compared to the use of kale alone, but still better than the control. the usen of the control without aquatic plants gave the lowest results. in conslusion, the use of water spinach as a biofilter media in aquaponic farming can significantly increase the growth of dumbo catfish seedlings. keywords: filter, water quality, growth rate, survival rate
