Judul: Karakteristik Karkas Kuda Dengan Umur, Jenis Kelamin Dan Pemanfaatan Yang Berbeda Di Kecamatan Binamu, Kabupaten Jeneponto Sulawesi Selatan
Abstrak: The study was conducted on local horse, aiming to identify the carcass characteristics of horse of different usefull (meat and draft) at different age groups (I2, I3, and I4) and sex (yeld mare and stallion). The experiment was carried out at the Horse Slaughter Place in Binamu district of Jeneponto regency, South Sulawesi. The parameters observed included body weight, carcass weight and percentage, meat and bones percentage and non carcass percentage. The results showed that sex and horse usefull had a highly significant (P<0.01) effect on carcass percentages. The carcass percentage of the stallion (59.78±1.97%) was abviously lower than that of the yeld mare (60.74±1.63%). The carcass percentage of draft type (59.88±2.52%) was abviously lower than meat type (60.59±1.86%). The influence of age on meat and bone percentage was highly significant (P<0.01). The meat percentage of I2 animal (64.53±5.68 %) was obviously lower than that of I4 animal (70.47±5.59%). Whereas, the bone percentage of I2 animal (35.47±5.68%) was obviously higher than I4 animal (29.53±5.95%). The influence of sex on bone percentage was significant (P<0.05). The bone percentage of yeld mare (29.83±5.65%) was abviously lower than of stallion (34.92±6.06%). The influence of age, sex, and different usefull on non carcass percentage was very significant (P<0.01). Non carcass percentage of I4 animal (37.90±1.70%) was obviously lower than that I2 animal (38.81±2.69 %). Non carcass percentage of meat horse (37.01±1.53%) was abviously lower than that draft horse (39.73±2.09%). Non carcass percentage of the stallion (37.67±1.94%) was abviously lower than that the yeld mare (38.54±2.39%).

Judul: Physical Characteristic of Buffalo Meat at Different Ages and Sexes
Abstrak: Kerbau merupakan salah satu ternak alternatif penghasil daging sebagai sumber protein hewani. Daging kerbau belum banyak diminati oleh konsumen. Bagian yang terpenting yang menjadi acuan konsumen dalam pemilihan daging adalah sifat fisik. Sifat fisik dalam hal ini antara lain warna, keempukan, kekenyalan, susut masak, dan kebasahan. Tujuan penelitian ini adalah untuk melihat pengaruh umur dan jenis kelamin yang berbeda terhadap sifat fisik daging kerbau. Daging kerbau yang digunakan sebagai sampel pada penelitian ini adalah bagian otot Longissimus dorsi et lumbarrum. Sampel diperoleh dari peternak kerbau di Kecamatan Menes, Labuan Cibaliung, Banos, Carita, Pagelaran, Panumbang, Sodong, Bojong dan Sakebi di Provinsi Banten. Penelitian dilaksanakan di Laboratorium Produksi Ternak Ruminansia Besar Departemen Ilmu Produksi dan Teknologi Peternakan, Fakultas Peternakan IPB. Rancangan percobaan yang digunakan yaitu rancangan acak lengkap faktorial 2x5. Faktor pertama jenis kelamin (jantan dan betina) dan faktor kedua umur (I0, I1, I2, I3, I4). Peubah yang diamati dari penilaian kualitas daging meliputi pH, keempukan, daya mengikat air (DMA), susut masak, dan warna. Data diuji dengan Analisis of Variance (ANOVA). Uji perbedaan Tukey dilakukan pada data yang berbeda nyata. Hasil pengujian menunjukkan bahwa susut masak dipengaruhi oleh kelompok umur (P<0,05) yang berbeda, tetapi tidak oleh jenis kelamin (P>0,05). Pengujian pada pH, keempukan, daya mengikat air, warna daging dan lemak tidak dipengaruhi oleh umur dan jenis kelamin diduga disebabkan oleh faktor manajemen pemeliharaan, pemotongan ternak, dan penanganan daging.

Abstrak: The solution of Schrodinger equations with plasma Coulomb potential in spherical coordinat results solution wave function and energy plasma particle. Electron probability density at Debye length with thermal effect same as ion, which indicates plasma in neutral state. Electromagnetic waves perturbation of an electric field given to result wave function perturbation system. The probability density of plasma particle due to electromagnetic waves perturbation is the largest when an electromagnetic waves frequency 1.41 times the plasma frequency .
