Judul: Body Size of The Eighth Generation of Cross-Bred  local Chickens (PSKM) Start 2nd Weeks to 12th Weeks of Age
Abstrak: Ayam pelung-sentul-kampung-meat type chicken (PSKM) adalah hasil dari persilangan antara F1 ayam pelung-sentul (PS) jantan dengan ayam meat typekampung (KM) betina untuk menghasilkan ayam lokal tumbuh cepat dan memiliki ukuran tubuh yang besar. Penelitian ini bertujuan menganalisa ukuran tubuh ayam PSKM generasi kedelapan (PSKM G8) dan membandingkan dengan generasi sebelumnya. Penelitian menggunakan 30 ayam jantan dan 30 ayam betina. Peubah yang diukur tiap 2 minggu adalah panjang shank, lingkar shank, panjang tibia, panjang femur, panjang punggung, lingkar dada, lebar dada, dalam dada, dan panjang dada. Analisis data hasil penelitian menggunakan analisis deksriptif. Hasil penelitian menunjukkan ayam PSKM G8 memiliki koefisien keragaman berkisar 0,72% sampai 8,84% pada setiap peubah yang diamati. Ayam PSKM G8 memiliki ukuran tubuh yang cukup seragam dibandingkan dengan generasi sebelumnya., Pelung-sentul-kampung-meat type chicken (PSKM) is a result of crossbreeding between F1 male pelung-sentul chickens (PS) with female meat typenative chickens (KM) to produce chickens that have fast growth and large body size. The aim of this study was to examine the body size of the eighth generation PSKM chickens (PSKM G8) and compare with the previous generation. The number of chickens used was 30 male chickens and 30 female chickens. The variables measured every 2 weeks were shank length, shank circumference, tibia length, femur length, back length, chest circumference, chest width, chest depth, and chest length. The research data were analyzed descriptively. PSKM chicken G8 had a coefficient of variant 0,72% to 8,84% on each variable observed. PSKM chicken G8 had a fairly uniform body size compared to the previous generation.

Judul: Ukuran Tubuh Ayam Hasil Persilangan Pelung X Sentul Dengan Kampung X Ras Pedaging Pada Umur 12 Sampai 22 Minggu
Abstrak: Penelitian ini bertujuan untuk mengobservasi ukuran tubuh ayam F1 pada fase pertumbuhan (12-22 minggu) dari hasil persilangan ayam pelung sem sentul (PS), ayam kampung ras pedaging (KB) dan ayam ras pedaging kampung (BK) Penelitian ini dilakukan pada bulan Desember 2014 sampai Mei 2015. Total ayam yang digunakan dalam penelitian ini ada 42 ekor yaitu jantan PSKB (12) Betina PKR (9), jantun PSBK (10) dan betina PSBK (8). Peubah yang diamats pada penelitian ini antara lain bobot badan, lingkar dada, panjang zihia, panjang fenner, ilin panjang dada. Uji T digunakan untuk membandingkan bobot hadan dan ukuran tubuh dari dua ayam persilangan. Hasil penelitian ini menunjukkan hohot badin antara jantan dan betina pada umur yang sama dan begitu juga pada ulouran tubuh (lingkar dada, panjang shiu, panjang femar, dan panjang dada) adalah sama antara ayam PSKB dan PSBK…

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.
