Penelitian ini bertujuan untuk mengevaluasi efektivitas sistem filterisasi inovatif dalam budidaya ikan dalam ember (budikdamber) terhadap pertumbuhan kangkung (Ipomoea reptans) di tiga lokasi berbeda, yaitu Tapian Nauli, STPK Matauli, dan Badan Pusat Statistik (BPS) Tapanuli Tengah. Metode yang digunakan adalah rancangan acak kelompok dengan dua perlakuan (sistem konvensional dan sistem filterisasi inovatif) dan tiga ulangan. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, dan laju pertumbuhan harian tanaman. Hasil menunjukkan bahwa penggunaan sistem filterisasi inovatif secara signifikan meningkatkan pertumbuhan tanaman dibandingkan sistem konvensional. Tinggi tanaman tertinggi diperoleh pada lokasi Tapian Nauli dengan sistem inovatif yaitu 26,3 ± 1,7 cm dan jumlah daun 11,5 ± 0,9 helai, dengan laju pertumbuhan harian sebesar 3,62%. Sistem filterisasi inovatif meningkatkan kualitas air melalui kombinasi filter mekanis dan biologis yang mendukung konversi amonia menjadi nitrat yang dapat dimanfaatkan oleh tanaman. Dengan demikian, sistem ini dapat menjadi solusi teknologi adaptif untuk meningkatkan produktivitas budikdamber secara berkelanjutan, terutama di kawasan pesisir dan pedesaan.
