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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
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.
