The purpose of this study was to determine the substitution of fermented water spinach waste (Ipomoea aquatica) in commercial feed on the performance of super free range female chickens. This study used 80 super free range female chickens aged 5 weeks. The research method used was a completely randomized design consisting of 4 treatments, each treatment consisted of 5 replications, and each replication consisted of 4 chickens. The treatments consisted of R0: 100% commercial ration, R1: 90% commercial ration + 10% water spinach waste fermented by tape yeast, R2: 80% commercial ration + 20%water spinach waste fermented by tape yeast, R3: 70% commercial ration + 30%water spinach waste fermented by tape yeast. The results of statistical analysis showed that the substitution of water spinach waste fermented by tape yeast on the performance of super female free range chickens with different treatments gave a significant (P<0,05) effect on ration intake, drinking water intake. But did not give a significant effect (P˃0,05) on body weight gain. Based on the results of the study, it can be concluded that the substitution of water spinach waste (Ipomoea aquatica) fermented by tape yeast to a level 30% in commercial feed increased ration intake and drinking water intake. However, at the substitution level of 20% the ration conversion rate increases.   Tujuan Penelitian ini adalah untuk mengetahui substitusi limbah kangkung air (Ipomoea aquatica) terfermentasi pakan komersial terhadap performa ayam kampung super betina. Penelitian ini menggunakan ayam kampung super betina sebanyak 80 ekor berumur 5 minggu. Metode penelitian yang digunakan adalah Rancangan Acak Lengkap yang terdiri dari 4 perlakuan, tiap perlakuan terdiri dari 5 ulangan, dan tiap ulangan terdiri dari 4 ekor ayam. Perlakuan yang diberikan terdiri dari R0: Ransum komersial 100%, R1: Ransum komersial 90% + 10% limbah kangkung airterfermentasi ragi tape, R2: Ransum komersial 80% + 20% limbah kangkung airterfermentasi ragi tape dan R3: Ransum komersial 70% + 30% limbah kangkung air terfermentasi ragi tape. Hasil analisis statistik menunjukan bahwa substitusi limbah kangkung air terfermentasi ragi tape terhadap performa ayam kampung super betina dengan perlakuan berbeda memberikan pengaruh nyata (P˂0,05) terhadap konsumsi ransum, konsumsi air minum dan konversi ransum. Tetapi tidak memberikan pengaruh nyata (P˃0,05) terhadap pertambahan bobot badan. Berdasarkan hasil penelitian dapat disimpulkan bahwa substitusi pemberian limbah kangkung air (Ipomoea aquatiaca) terfermentasi ragi tape sampai level 30% pada pakan komersial meningkatkan konsumsi ransum dan konsumsi air. Namun pada level substitusi 20% nilai konversi ransum meningkat.
