Abstrak: Duck eggs are more difficult to hatch than chicken eggs as the duck does not incubate their eggs and the duck eggs need more time to hatch (in 28 days). This study aimed to determine the sex ratio of DOD (Day Old Duck) from two different breeds, namely cihateup from Tasikmalaya West Java and alabio from South Kalimantan. This experiment was conducted from May 2012 to July 2012 at the Hatchery Laboratory of Animal Science Faculty of IPB. 500 eggs consist of 300 alabio eggs and 200 cihateup eggs were used in this experiment. Temperature, humidity, egg weight, egg shape index, hatching weight and mortality were measured. The data of egg weight, egg shape index, and hatching weight were analyzed using t-test, the data of sex ratio DOD were analyzed using chi-square test. The result showed that there were no significant difference between egg weight and egg shape index on sex ratio. Sex ratio of male and female cihateup ducks was equal (50%:50%), however the sex ratio of alabio ducks was different (32%:68%). Mortality rate was affected by sex of duck (P<0.05). The Higher mortality was occured at early (day 0-7) and late (day>25) hatching period.

Abstrak: Hatchability of duck lower than the chicken and quail. Dirty egg shell can cause low hatchability. The use of disinfectants is aimed to suppress the growth of bacteria on the eggshell. Lemon is a natural disinfectants. This research was aimed to determine hatchability of Alabio (A) and Cihateup-Alabio (CA) crossbreed duck eggs by using natural sanitary materials of lemon juice for soaking eggs. Egg weight, egg shape index, fertility, hatchability, hatching weight, and the death of the embryo were analyzed descriptively. The correlation between egg weight and hatching weight was subjected to regression analyses. Egg weight and egg fertility of CA duck was higher than Alabio duck. Alabio duck egg shape index was greater than that of CA duck. Hatchability of CA eggs was higher than that of Alabio duck. The most high embryo mortality occurred in the period of hatcher (> 25 days). Regression analyses revealed strong correlation between egg weight and hatching weight. The high egg weight produces a high hatching weight.

Judul: Quantum Convolutional Neural Network (QCNN) for Classification Brain Tumor MRI Image
Abstrak: Penelitian ini bertujuan untuk mengembangkan model deteksi tumor otak menggunakan citra MRI dengan metode Quantum Convolutional Neural Network. Data yang digunakan adalah citra MRI otak yang terdiri dari citra tumor otak glioma, meningioma, hipofisis, dan negatif tumor yang dibagi kedalam data latih dan uji dengan rasio 80:20. Selanjutnya data latih dilakukan penyeimbangan dengan teknik oversampling. Dilakukan pengembangan model untuk mendeteksi tumor otak (biner), dan juga model untuk mengklasifikasikan jenis tumor otak (multiclass). Parameter yang digunakan dalam pengembangan model adalah jumlah ukuran filer = 2 dan kedalaman = 4, dengan qubit 4, dan dilatih dengan jumlah epoch sebanyak 10. Data akan diproses dengan metode Quantum Convolutional Neural Network yang terdiri dari lapisan quantum convolution, lapisan flatten, dan lapisan dense. Model multiclass mendapatkan akurasi 52%, setelah data latih diseimbangkan akurasi model meningkat menjadi 62%, sedangkan model biner mendapatkan akurasi 88%, setelah data latih diseimbangkan akurasi model meningkat menjadi 89%.
