Judul: Penyusutan dan Mortalitas Ayam Broiler pada Jarak Tempuh yang Berbeda Selama Pengangkutan
Abstrak: Transportation aspects of broiler chickens to slaughterhouse are concerned to reduce bodyweight and to increase number of mortality. The experiment was conducted to study the bodyweight loss and mortality of broiler chickens caused by transportation with different travelling distances. Chickens were transported to slaughterhouse at age of 40 days with average bodyweight at 1.5 kg and delivered from 3 different farms location in Bogor (50 km), Lebak (83 km), and Pandeglang (153 km), and observation was 3 times replicated. The percentage of bodyweight loss during travelling from Bogor, Lebak, and Pandeglang was 3.33 ± 0.06%, 3.73 ± 0.76%, and 4.50 ± 1.13%, respectively. The percentage of mortality during travelling from Bogor was 0.26 ± 0.17%, Lebak 0.74 ± 0.56%, and Pandeglang 0.46 ± 0.35%. There is a linear correlation between the percentage of bodyweight loss and the travelling distances of transported broiler chickens. but there is no correlation between mortality and the travelling distances. The highest percentage of mortality were from Lebak (83 km), Pandeglang (153 km), and Bogor (50 km), respectively.

Judul: The Impacts of Transport at Different Time Against Antemortem Condition, Weight Loss and Mortality of Broiler Chickens
Abstrak: Transportasi merupakan suatu aspek yang perlu untuk dilakukan, diperhatikan dan tidak dapat dihindari dalam mendistribusikan ternak untuk memenuhi kebutuhan suplai pasar. Penelitian bertujuan untuk menganalisis pengaruh waktu transportasi yang berbeda terhadap kondisi antemortem, susut bobot dan mortalitas ayam broiler. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL), dengan 3 perlakuan dan 3 ulangan sehingga terdapat 9 unit percobaan setiap unit percobaan menggunakan sampel sebanyak 5 ekor ayam broiler. Perlakuan 1 pagi hari (08.00 WIB) dengan waktu tempuh selama 125 menit, perlakuan 2 siang hari (12.00 WIB) dengan waktu tempuh selama 133 menit dan perlakuan 3 sore hari (16.00 WIB) dengan waktu tempuh selama 141 menit. Berdasarkan hasil analisis ragam menunjukkan bahwa waktu transportasi memberikan pengaruh yang sangat nyata (P<0.01) terhadap jumlah luka parut,susut bobot dan persentase susut bobot, namun tidak berpengaruh terhadap luas luka parut (cm2), jumlah memar pada dada, luas memar pada dada (cm2), jumlah memar pada sayap, luas memar pada sayap (cm2), dan persentase mortalitas. Transportasi pada pagi hari baik untuk dilakukan karena memiliki nilai persentase susut bobot dan mortalitas yang paling rendah dibandingkan perlakuan lainnya., Transportation is an aspect that needs to be done, considered and cannot be avoided in distributing livestock to meet market supply needs. This study aimed to analyze the effect of different transport times on antemortem conditions, weight loss and mortality of broiler chickens. This study used a completely randomized design (RAL), with 3 treatments and 3 replications so that there are 9 experimental units each experimental unit uses a sample of 5 broiler chickens. Treatment 1 in the morning (08.00 WIB) with a travel time of 125 minutes, treatment 2 in the afternoon (12.00 WIB) with a travel time of 133 minutes and treatment 3 in the afternoon (16.00 WIB) with a travel time of 141 minutes. Based on the results of the analysis of variance, it showed that transportation time had a very significant effect (P<0.01) on the number of scars, weight loss and percentage of weight loss. but did not affect the area of the scar (cm2), the number of bruises on the chest, the area of bruises on the chest (cm2), the number of bruises on the wings, the area of bruises on the wings (cm2), and the percentage of mortality. Transportation in the morning is good to do because it has the lowest percentage value of weight loss and mortality compared to other treatments.

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+.
