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: 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.

Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
