Judul: Penilaian Tingkah Laku Sapi Brahman Cross Selama Proses Loading dan Unloading
Abstrak: Proses loading dan unloading merupakan proses yang sangat memicu stress. Penelitian ini bertujuan untuk mengevaluasi proses loading dan unloading dengan melihat lama waktu dan tingkah laku yang muncul. Penelitian ini menggunakan 24 loading grup dengan masing-masing grup berisikan 11 ekor sapi Brahman cross yang memiliki rataan berat 521±28.14 kg. Data yang diperoleh dianalisis secara deskriptif meliputi persentase,frekuensi,skor, dan rataan skor. Hasil pengamatan menunjukkan bahwa proses loading memiliki nilai durasi waktu S (sangatburuk) dan nilai tingkah laku 3 (sedang) sedangkan proses unloading memiliki nilai durasi waktu T (sangat baik) dan nilai tingkah laku 3 (sedang). Perilaku slips, jump, dan fall merupakan perilaku yang sering muncul selama proses loading dan unloading. Proses loading lebih berpotensi menimbulkan stress dibandingkan dengan proses unloading.

Judul: Physiological Response, Behavior and Performance of Ongole Grade and Local Crossbreed Cattle on Short Distance Transportation
Abstrak: Transportasi merupakan elemen penting dalam rantai industri sapi pedaging. Penelitian ini bertujuan mengevaluasi respon fisiologis, tingkah laku dan performa Sapi Peranakan Ongole dan Sapi Silangan Lokal selama rekodisi pada proses transportasi jarak dekat. Penelitian ini menggunakan Sapi Peranakan Ongole (PO) dan Silangan Lokal Jantan masing-masing 8 ekor dengan umur I1-I2 (18-30 bulan). Rataan bobot badan Sapi Peranakan Ongole dan Silangan Lokal berturut-turut adalah 291,5±23,5 kg dan 289,0±26,4 kg. Peubah yang diamati meliputi kondisi mikroklimat lingkungan, respon fisiologis, tingkah laku dan performa ternak. Hasil penelitian menunjukkan bahwa berdasarkan nilai THI, sapi mengalami stres panas sedang selama transportasi dan stres panas ringan selama rekondisi. Respon fisiologis dan penyusutan bobot badan Sapi Peranakan Ongole dan Silangan Lokal adalah sama. Tingkah laku dominan saat proses pemuatan (loading) dan penurunan (unloading) adalah adalah tergelincir yaitu masing-masing sebesar 30,8% dan 32,7%. Rataan penyusutan bobot badan Sapi Peranakan Ongole 7,0±4,0 kg (2,5%) dan Sapi Silangan Lokal 9,3±5,3 kg (3,1%). Selanjutnya lama rekondisi Sapi Peranakan Ongole dan Silangan Lokal sama yaitu selama 10 hari., Transportation is an important element in beef industry. This study aims to evaluate the physiological response, behavior and performance during recondition period of Ongole and Local Crosbreed Cattle in short distance transportation. This study used 8 Ongole Crossbreed and 8 Local Crossbreed Cattle bull with average age of I1-I2 (18-30 months). The average body weight of Ongole and Local Crossbreed Cattle were 291,5±23,5 kg and 289,0±26,3 kg respectively. The parameters observed were environmental microclimate conditions, physiological responses, behavior and performance of cattle. The results of THI showed that cattle was on medium heat stress during transportation and mild heat stress during recovery time. Physiological response and body weight loss of Ongole grade and Local Crossbreed Cattle were similar. The dominant behavior during loading and unloading process was slips, which were 30,8% and 32,7% respectively. Average body weight loss of Ongole grade and local crosbreed were 7,0±6,8 kg (2,5%) and 9,3±5,3 kg (3,1%). Furthermore, length of recovery time of Ongole and Local Crosbreed Cattle was similar for ten days.

Judul: Sintesis dan Pencirian Kompleks Fe(III)-Kuersetin
Abstrak: Quercetin belongs to flavonols which is able to chelate metal ions. Quercetin may chelate metal ions at 3’,4’-catechol, 3- or 5-hydroxycromone sites. In this study, quercetin was complexed with Fe(III). The complex with Fe(III) ions from FeCl3·6H2O was more stable than the complex derived from Fe(NO3)3·9H2O. The quercetin was yellow in color and showed maximum wavelengths (λ􀭫􀭟􀭶) at 250 and 370 nm. The Fe(III)-quercetin complex from Fe(NO3)3·9H2O was yellowish green with 􀟣􀭫􀭟􀭶 at 280 and 420 nm, whereas that from FeCl3·6H2O was dark green with 􀟣􀭫􀭟􀭶 at 280 and 430 nm. The 􀟣􀭫􀭟􀭶 shift indicated that the complex was formed at 3-hydroxychromone site. The Fe(III)- quercetin complex was formed with 1:1 metal-ligand mole ratio based on atomic absorption spectrophotometry analysis and the X-ray diffractogram showed that the crystallinity of the complex was 37%.
