Penelitian ini bertujuan untuk mengetahui produksi kayu apu (Pistia stratiotes L.) dengan berat tebar berbeda dan kualitas air pemeliharaan kayu apu (Pistia stratiotes L.) dalam kolam budidaya lele (Clarias sp.) secara intensif. Pengamatan produksi kayu apu (Pistia stratiotes L.) dengan berat tebar : 30, 60, 90, dan 120 gram per 150 cm2 keranjang; kualitas air; serta pertumbuhan lele dilakukan setiap 2 minggu sekali. Data produksi kayu apu (Pistia stratiotes L.) dianalisis menggunakan analisis uji Regresi, sedangkan data kualitas air dan pertumbuhan ikan dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa berat tebar kayu apu (Pistia stratiotes L.) yang semakin tinggi (30, 60, 90, 120 gram per 150 cm2 keranjang), memberikan produksi (pertambahan berat) mutlak dan spesifik kayu apu (Pistia stratiotes L.) segar dan kering yang semakin tinggi. Selama budidaya lele, kualitas air sesuai untuk pertumbuhan kayu apu (Pistia stratiotes L.). Kesuburan air budidaya lele (Clarias sp.) semakin lama semakin meningkat dan menghasilkan produktivitas kayu apu (Pistia stratiotes L.) yang semakin tinggi.

This study aimed to determine the production of water cabbage (Pistia stratiotes L.) with different stocking weight and the water quality for water cabbage (Pistia stratiotes L.) cultivation in intensive catfish (Clarias sp.) culture pond. Observation of water cabbage (Pistia stratiotes L.) production with stocking weight of 30, 60, 90 and 120 grams per 150 cm2 basket; water quality; and catfish growth were carried out every 2 weeks. The production of water cabbage (Pistia stratiotes L.) was analyzed using Regression test analysis, while the water quality and fish growth data were analyzed descriptively. The results showed that the stocking weight of the water cabbage (Pistia stratiotes L.) were higher (30, 60, 90, 120 grams per 150 cm2 basket), produced absolute and specific weight of water cabbage (Pistia stratiotes L.) in fresh and dry plants were getting higher. During catfish culture, the quality of water were suitable for the growth of water cabbage (Pistia stratiotes L.). The water fertility of catfish (Clarias sp.) pond were increasing, and so on the productivity of water cabbage (Pistia stratiotes L.) were also getting higher.
