Judul: impact of transportation to broiler chicken (Gallus domesticus) physiology responses
Abstrak: Kegiatan transportasi akan menimbulkan stres pada ayam yang akan menimbulkan dampak negatif dengan turunnya bobot badan dan mortalitas yang akan mempengaruhi pendapatan. Tingkat stres yang dirasakan ayam dipengaruhi oleh kondisi lingkungan mikro selama transportasi. Stres pada ayam dapat diidentifikasi dari suhu tubuh yang tinggi, peningkatan denyut jantung, dan frekuensi pernapasan yang disebut sebagai respon fisiologis pada ayam. Penelitian ini dilakukan untuk mengetahui pengaruh transportasi terhadap respon fisiologis ayam. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola Faktorial A(2) × B(2). Faktor A perlakuan ditransportasikan dan tidak ditransportasikan. Faktor B waktu pengamatan sebelum dan sesudah Faktor A. Hasil penelitian menunjukkan ada interaksi antara perlakuan A dan B pada pengamatan frekuensi pernapasan dan suhu rektal. Pada pengamatan denyut jantung dan bobot badan tidak ada interaksi antara perlakuan A dan B. Adanya pengaruh suhu relatif yang rendah karena aliran udara saat dilakukan proses transportasi dimalam hari sehingga peningkatan respon fisiologis pada perlakuan ditransportasikan lebih rendah dibandingkan pada perlakuan tidak ditransportasikan., Transportation activities will cause stress on chickens and will harm decreased body weight and mortality that will affect income. The level of stress felt by chickens is influenced by microenvironmental conditions during transportation. Stress in chickens can be identified by high body temperature, increased heart rate, the respiratory rate which is called a physiological response in chickens. This study was conducted to determine the effect of transportation on the physiological response of chickens. This study used a Completely Randomized Design (CRD) with factorial pattern A(2) × B(2). Factor A treatment was transported and not transported. Factor B was observed before and after Factor A. The results showed that there was an interaction between treatments A and B on the observation of respiratory frequency and rectal temperature. In the observation of heart rate and body weight, there was no interaction between treatments A and B. There was a relatively low effect of temperature due-airflow flow during the transportation process at night at the increase in physiological response in the transported treatment was lower than in the non-transported treatment.

Judul: Pengaruh Penyiraman  Sebelum Proses Transportasi Terhadap Respon Fisiologis Ayam Broiler
Abstrak: Broiler chickens are chickens used for the purpose of producing meat. The chicken farming industry is highly dependent on the transportation process, both from the location of the farm to the chicken slaughterhouse (RPA). This study aims to analyze the differences in the physiological response of broiler chickens to the treatment of being given water sprinkling and not being given water sprinkling before transportation Signs of stress in broiler chickens during transportation are increased heart rate, increased respiratory respiration, increased rectal temperature and decreased body weight. The livestock used were 78 broiler chickens ready for harvest this week, with an average weight of 1,843±0,023 g. The procedures carried out include loading, traveling, and unloading. The observed variables were microclimate, heart rate, respiration frequency, rectal temperature, weight loss. Data were analyzed using RAL factorial 2x2. The result showed that broiler chickens that received watering treatment had lower physiological response values and reduced body weight.

Judul: Sintesis dan Pencirian Senyawa 4-Dodekanadioilbis(1-fenil-3-metil-5-pirazolon) sebagai Ionofor untuk Penentuan Ion Lu3+ dengan Teknik Elektrode Selektif Ion
Abstrak: Ion selective electrode (ISE) as an alternative potentiometric method is used widely in determining Lu3+. The success of this method depends on the ionophor used on the ISE. The compound of 4-dodecanedioylbis(1-phenyl-3-methyl-5-pyrazolone) or H2DdBP as pyrazolone derivatives will be used as ionophor on ISE-Lu3+. H2DdBP had been successfully synthesized by Jensen’s method. This method involved reaction of 1-phenyl-3-methyl-5-pyrazolone and dodecanedioyl chloride in basic condition. A compound was produced as a solid substance and was purified by recrystallization using chloroform-ethanol. High performance liquid chromatogram showed that the compound was pure. The compound was in keto form with melting point range of 150-152ºC. Infrared spectra showed vibration peaks (cm-1) were 3451 (br, OH), 1624 (s, C=O), 1589 (s, phenyl C=C), 1558 (s, pyrazolone ring). Chemical shifts (Hz) for 1H-NMR were 7.81–7.84, 7.43–7.46, 7.26–7.290 (m, 10H, Ph); 2.72–2.75 (t, 4H, (CH2)2); 2.47 (s, 6H, CH3); 1.71–1.76 (m, 4H, (CH2)2); 1.32 (m, 12H, (CH2)6). All of these properties showed the characteristics of H2DdBP. Nernst factor of ISE-Lu3+ for two repetitions were 10.40 mV/decade and 8.60 mV/decade which showed that ISE-Lu3+ had good response in determining Lu3+.
