摘要：ABSTRACT Magelang duck is the Indonesian wild duck that have high egg and meat production. To increase egg production hence in this research magelang ducks are supplemented with curcumin and exposure of white and red light. The aim of the research to study growth beak duckling from parental magelang ducks that supplemented curcumin and red light exposure. The research design used complete randomized design from fourdifferents group of ducks, i.e., A 0 B 0 (duck without curcumin and white light exposure), A 0 B 1 (duck without curcumin and red light exposure), A 0 B 1 (curcumin dose of 18 mg/duck/day and white light exposure and A 1 B 1 (curcumin dose 18 mg/duck/day and red light exposure). Five female ducklings were taken from each group and their morphometry were measured. The variables of this research were the length, width and height of beaks. The collected data were analized with Kruskal-Wallis non parametric test and would be further tested with Mann-Whitney-U test. The result of this research showed that curcumin supplementaion and red light exposure in ducks affected the magelang ducklings beak growth. Keywords : beaks, curcumin, growth, magelang ducks, red light. ABSTRAK Itik magelang merupakan itik liar asli Indonesia yang memiliki produksi telur dan daging relatif tinggi. Untuk meningkatkan produksi telur maka pada penelitian ini itik magelang diberi suplementasi kurkumin serta pajanan cahaya putih dan merah. Penelitian ini bertujuan untuk mengkaji pengaruh pemberian kurkumin serta cahaya putih dan merah pada induk terhadap pertumbuhan paruh anak itik magelang. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap (RAL) yang berasal dari empat induk yang berbeda, yaitu induk A 0 B 0 (tanpa diberi kurkumin dan dipapar cahaya putih), A 0 B 1 (tanpa diberi kurkumin dan dipapar cahaya merah), A 1 B 0 (dosis kurkumin 18 mg/ekor/hari dan paparan cahaya putih) dan A 1 B 1 (dosis kurkumin 18 mg/ekor/hari pada cahaya merah). Masing-masing kelompok induk diambil lima ekor anak itik untuk diukur paruhnya. Variabel yang diamati berupa pengukuran panjang, lebar, dan tebal paruh. Data yang diperoleh dianalisis menggunakan uji non parametrik Kruskal-Wallis dan diuji lanjut menggunakan uji Mann-Whitney-U. Hasil penelitian ini menunjukkan bahwa suplementasi kurkumin dan pajanan cahaya putih serta merah pada induk secara umum dapat meningkatkan pertumbuhan paruh anak itik.
