      Abstract
      Duckweed (Lemna sp.) merupakan tanaman air yang berpotensi sebagai pakan alternatif ikan dengan kandungan nutrien yang tinggi. Penelitian ini bertujuan untuk menguji pengaruh penambahan duckweed dengan metode kering dan basah yang dikombinasikan pada pakan terhadap laju pertumbuhan ikan nila. Penelitian dilakukan selama 60 hari menggunakan rancangan acak lengkap dengan 3 perlakuan pakan, yaitu kontrol, DK (penambahan duckweed kering 15%), DB (penambahan duckweed basah 15%) dengan masing-masing tiga kali ulangan. Hasil menunjukkan bahwa penambahan duckweed, baik kering maupun basah, tidak memberikan pengaruh nyata terhadap laju pertumbuhan ikan nila. Namun, perlakuan duckweed basah memberikan hasil terbaik terhadap kelangsungan hidup dan jumlah konsumsi pakan. Dari aspek histologi, perlakuan duckweed kering menunjukkan tinggi vili (TV) yang lebih tinggi dan luas area penyerapan (LAP) yang lebih besar dibanding duckweed basah. Meskipun tidak berpengaruh nyata terhadap laju pertumbuhan, penambahan duckweed basah dapat meningkatkan kelangsungan hidup dan konsumsi pakan yang lebih ekonomis. Sementara itu, duckweed kering berpotensi memperbaiki struktur histologi usus. Duckweed dapat digunakan sebagai bahan pakan alternatif yang mendukung budidaya ikan nila yang lebih efisien.
       
      Duckweed (Lemna sp.) is an aquatic plant that has potential as an alternative fish feed with high nutrient content. This study aims to determine the effect of adding duckweed with dry and wet methods combined in feed on tilapia growth rate. The study was conducted for 60 days using a completely randomized design with 3 feed treatments namely control, DK (addition of 15% dry duckweed), DB (addition of 15% wet duckweed) with three replicates each. The results showed that the addition of duckweed, both dry and wet, did not significantly affect the growth rate of tilapia. However, the wet duckweed treatment gave the best results on survival and feed consumption. In terms of histology, the dry duckweed treatment showed higher villi height (TV) and larger absorption area (LAP) than the wet duckweed. Although there was no significant effect on growth rate, the addition of wet duckweed increased survival and feed consumption, which was more economical. Meanwhile, dried duckweed has the potential to improve intestinal histology structure. Duckweed can be used as an alternative feed ingredient that supports more efficient tilapia farming.
