Judul: Physical Quality of Duck Meat Sold in Traditional Markets in Bogor City
Abstrak: Peminat daging bebek yang semakin meningkat harus diikuti dengan peningkatan kualitas daging bebek. Kualitas dapat ditingkatkan dengan menerapkan kesejahteraan hewan pada tempat pemotongan. Penelitian bertujuan memberikan gambaran kualitas fisik daging bebek yang dijual di pasar tradisional Kota Bogor. Sebanyak 45 sampel daging bebek diambil dari 7 pedagang pada tiga pasar di Kota Bogor. Pengujian kualitas fisik daging yang dilakukan meliputi pengujian pH, drip loss, dan susut masak. Hasil penelitian didapatkan bebek dengan uumur > 7 minggu jarang ditemukan. Nilai pH daging bebek didapatkan berada pada nilai normal dengan rentang 6,10–6,39 di bagian paha. Uji drip loss pada daging bebek memiliki nilai tertinggi 16,70±13,43 pada bebek berumur > 7 minggu dan nilai terendah 10,57±10,81 pada bebek berumur = 7 minggu. Uji susut masak menunjukkan nilai tertinggi 28,77±8,55 pada bebek berumur > 7 minggu dan nilai terendah 24,56±9,18 pada bebek berumur = 7 minggu. Terdapat temuan berupa pendarahan pada bagian dada bebek indikasi perlakuan kasar sebelum pemotongan. Data tersebut menunjukkan daging bebek di pasar tradisional Kota Bogor layak di dikonsumsi masyarakat dengan kualitas terbaik pada bebek umur muda (= 7 minggu).

Judul: Persentase dan Kualitas Karkas Itik Cihateup-Alabio (CA) pada Umur Pemotongan yang Berbeda
Abstrak: Low demand of duck meat is influenced by its quality. Generally, ducks slaughtered at 8 weeks have low carcass quality. Slaughter age is expected to influence carcass quality. Therefore, the study of carcass quality in different slaughter ages (8, 10, and 12 weeks) is needed. This research used 32 males and 18 females cihateup-alabio (CA) ducks. Ducks were grouped by hatching period. The experiment design was randomized block factorial (3x2). Treatments were slaughter age and sex. Traits measured were slaughter weight, percentage of carcass and its parts, physical and sensory quality of duck carcass. The result showed that interaction of slaughter age and sex affect slaughter weight. The higher slaughter age resulted higher breast and abdominal fat percentage, but had smaller thigh percentage. Sex had no effect on carcass percentage and its parts. Higher slaughter age and male sex showed better phisycal carcass quality. Differences in slaughter age and sex had no effect on panelist preference. This research concluded that higher slaughter age produces better carcass percentage and quality.

Abstrak: A mathematical method is introduced to represent a composite curve based on an extension of analytic geometry. The representation is given either with a single equation or with two equations, in the case of parametric representation. This method permits the representation of composite curves in similar manner to the conventional representation of non-composite curves. Some mathematical tools, including Heaviside unit step function and periodizer function, are used in the establishment of a single equation. In this paper, regular equations of regular and irregular polygon, as well as composite curves of two dimensions, are implemented using a computer algebraic system, Mathematica.
