KEUNTUNGAN INTRODUKSI TERNAK ITIK YANG DIBERI PAKAN MAGGOT DI LAHAN SAWAH DENGAN DAN TANPA AZOLLA = THE ADVANTAGES OF INTRODUCING DUCK FARMING FED DIETARY MAGGOT IN PADDY FIELD WITH AND WITHOUT AZOLLA

MUH ALFIANSYAH L. The advantages of introducing duck farming fed dietary maggot in paddy field with and without azolla (supervised Djoni Prawira Rahardja dan Rusnadi Padjung). This research was to analyse the advantages of introducing Hermetia illucens (maggot) larvae to the diet of ducks during integrated rice duck farming with and without azolla. This study was carried out in South Sulawesi, Indonesia. The research was arranged as a factorial experiment, based on randomized design with three replications. The first factor was azolla and maggot combination with four levels, D1(-azolla,-maggot), D2(+azolla,-maggot), D3(-azolla,+maggot), D4(+azolla,+maggot). The second factor was duck density with two levels, P1(3 ducks/10m2), P2(5 ducks/10m2). Ducks were introduced between 28-56 days after planting. Parameters: rice production (number of panicles, grain number per panicle, rice yield), duck performances (body weights, weight gain, feed intake, feed conversion). The results showed that there was increase the advantages of introducing ducks at density of five, as the rice yield was heavier compared to three ducks, and duck performance was not affected by differences duck density, which increased productivity by optimal revenue per land. The combination of azolla and maggot did not affect rice production, but it affected duck performance, as body weight and weight gain increased through feed intake of ducks given combination D2(+azolla,-maggot) resulted in better feed conversion. Meanwhile, revenue-cost ratio (RCR) of duck production at density of five ducks with combination D4(+azolla,+maggot) had the highest advantage RCR of 1.43, but rice production was lower RCR of 3.54 than D3(-azolla,+maggot) RCR of 3.87. In conclusion, This study introduces the potential of duck farming in rice fields as an alternative in production process to optimize rice production, duck performance, and advantages in rice and duck.
