Judul: Morphometric Comparison of Female Local Crossbred in Different Age Groups in The Wadung Village of Tuban District
Abstrak: Sapi silangan lokal merupakan sapi hasil persilangan antara bangsa sapi lokal dengan bangsa sapi impor yang diharapkan sapi memperoleh sifat-sifat yang diinginkan sehingga banyak dikembangkan di Indonesia, terutama di Kabupaten Tuban. Tujuan dari penelitian ini menganalisis perbandingan morfometrik sapi silangan lokal betina pada berbagai kelompok umur di Desa Wadung, Kabupaten Tuban. Metode penelitian ini menggunakan analisis deskriptif dan analisis Uji T. Parameter tubuh yang diukur meliputi panjang badan, tinggi badan, lebar dada, dalam dada, lingkar dada, tinggi panggul, lebar panggul, panjang kepala, dan lebar kepala. Perhitungan rasio tubuh dan indeks morfometrik juga dilakukan. Selain itu, perbandingan dengan standar yang berlaku juga dilakukan. Hasil pengukuran morfometrik menunjukkan terdapat perbedaan pada parameter tinggi panggul umur I2 (>24 - 36 bulan) yang lebih tinggi sapi silangan limousin betina. Sedangkan perbandingan rasio ukuran tubuh dan indeks morfometrik sapi tidak terdapat perbedaan sehingga kedua sapi memiliki proporsi tubuh yang seimbang. Sapi silangan simmental dan silangan limousin sudah mencapai standar kuantitatif bibit pada umur I1 (18 - 24 bulan), namun pada umur I0 (< 18 bulan) masih dibawah standar kuantitatif bibit., The local crossbred cattle are the crossroads between local cattle and imported cattle, which are expected to acquire the desired characteristics so that they are developed in Indonesia, especially in Tuban district. The purpose of this study is to analyze the morphometric comparisons of local female cattle in different age groups in Wadung Village, Tuban District. This method of research uses descriptive analysis and analysis T. The body parameters measured include body length, height, chest width, chest depth, chest circumference, hip height, hip width, head length, and head width. Calculation of body ratio and morphometric index is also done. In addition, comparisons with the applicable standards are also carried out. The morphometric measurement results showed that there was a difference in the high pelvic parameters of the I2 age (>24 - 36 months) of the higher female limousine cattle. While comparing the ratio of body size and the morphometric index of cows there is no difference so that both cows have balanced body proportions. Simmental cross cattle and limousine cross cattle have reached the quantitative standard of sowing at the age of I1 (18-24 months), but at age I0 (<18 months) they are still below the qualitative standard for sowing.

Judul: Morphometric Analysis of Cattle in Central  Lampung based on Breed, Sex, and Different Body Weight Groups
Abstrak: Bos taurus merupakan spesies sapi yang diimpor memiliki kerangka tubuh besar sehingga banyak dipelihara dan dikembangkan di Indonesia, terutama di Lampung Tengah. Tujuan dari penelitian ini untuk menganalisis morfometrik sapi di Lampung Tengah pada bangsa dan jenis kelamin serta kelompok bobot badan berbeda. Metode penelitian ini menggunakan analisis deskriptif dan analisis parametrik independent samples t-test dan nonparametrik mann whitney u-test. Peubah yang diamati meliputi morfometrik panjang badan, tinggi badan, tinggi panggul, lebar panggul, lingkar dada, dan dalam dada. Perhitungan rasio tubuh dan perbandingan dengan standar yang berlaku juga dilakukan. Hasil pengukuran menunjukkan secara keseluruhan sapi Limousin jantan dan betina lebih besar dibandingkan sapi Simmental. Rasio tubuh menggambarkan sapi Simmental jantan bobot badan >300 kg memiliki bagian belakang yang lebih besar, sedangkan seluruh sapi Simmental betina dan Limousin memiliki proporsi tubuh yang seimbang. Sapi Simmental dan Limousin sudah mencapai standar kuantitatif bibit, hanya sapi Simmental jantan pada ukuran panjang badan dan lingkar dada yang belum mencapai ukuran minimum sehingga tidak disarankan untuk dijadikan bibit., Bos taurus, an imported cattle species with a large body frame, is extensively raised and developed in Indonesia, particularly in Central Lampung. The study aim of this research is to analyze the morphometrics of cattle in Central Lampung across different breeds, genders, and weight groups. This study employs descriptive analysis as well as parametric independent samples t-tests and nonparametric Mann-Whitney U-tests. Observed variables include morphometric measurements such as body length, height, pelvic height, pelvic width, chest circumference, and chest depth. Body ratios are calculated and compared against applicable standards. Measurement results indicate that overall, both male and female Limousin cattle are larger than Simmental cattle. Body ratios illustrate that male Simmental cattle weighing over 300 kg have larger hindquarters, while all female Simmental and Limousin cattle exhibit balanced body proportions. Simmental and Limousin cattle have already met the quantitative breeding standards, except for male Simmental cattle in terms of body length and chest circumference, which have not reached the minimum size and are not recommended for breeding purposes.

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 .
