Abstrak: ABSTRAK AHMAD FARID. Variabel Pembeda Ukuran Permukaan Tubuh Linear Ayam Kampung dan Ayam Nagrak. Dibimbing oleh RINI HERLINA MULYONO dan RUDI AFNAN. Ayam kampung dan ayam nagrak merupakan sumber daya genetik ternak unggas Indonesia yang sangat potensial untuk dikembangkan. Penelitian ini bertujuan untuk menentukan variabel pembeda ukuran permukaan tubuh linear antara ayam kampung dan ayam nagrak. Pengukuran terdiri atas panjang femur (X1), panjang tibia (X2), panjang tarsometatarsus (X3), lingkar tarsometatarsus (X4), panjang jari ketiga (X5), panjang sayap (X6), panjang maxilla (X7), dan tinggi jengger (X8). Penelitian ini menggunakan metode analisis diskriminan. Variabel pembeda antara ayam kampung jantan dengan nagrak jantan adalah X1, X2, X3, X4, X5, X6, dan X8, dan ayam kampung betina dan nagrak betina adalah X2, X3, X4, X5, X6, X7 dan X8. Persamaan diskriminan ayam kampung jantan dengan ayam nagrak jantan adalah Y=-0,57X1-0,31X2+1,10X3-0,47X4-0,98X5-0,20X6+0,46X8, serta persamaan diskriminan ayam kampung betina dengan nagrak betina adalah Y=-0,20X2+1,11X3-0,78X4-0,91X5-0,35X6-0,41X7-0,16X8. Klasifikasi data kelompok ayam jantan menunjukkan tidak tepat sebanyak 8 ekor ayam nagrak, sedangkan pada ayam betina menunjukkan semua sesuai dengan kelompoknya.

Supervised by RINI HERLINA MULYONO and RUDI AFNAN. Kampung chickens and nagrak chickens are Indonesian poultry genetics resources that have the potential to be developed. This study aimed to determine the variables that distinguish the size of the linear body surface of kampung and nagrak chickens. Linear body surface measurements consisted of femur length (X1), tibia length (X2), tarsometatarsus length (X3), tarsometatarsus circumference (X4), third finger length (X5), wing length (X6), maxilla length (X7), and comb height (X8). This research used the discriminant analysis. Distinguish variables between cock kampung and nagrak chickens are X1, X2, X3, X4, X5, X6, and X8. Distinguish Variables between hen kampung and nagrak chickens are X2, X3, X4, X5, X6, X7 and X8. The discriminant equation of cock kampung to nagrak chicken is Y=-0,57X1-0,31X2+1,10X3-0,47X4-0,98X5-0,20X6+0,46X8 and the discriminant equation of hen kampung and nagrak chicken is Y=-0,20X2+1,11X3-0,78X4- 0,91X5-0,35X6-0,41X7-0,16X8. The data classification of the cock chicken group showed that 8 nagrak chickens were inaccurate, while the hen chickens group showed that all of them were in the right group.

Judul: Perbedaan Morfometrik Permukaan Tubuh Ayam Kampung Ciamis, Tegal dan Blitar Berdasarkan Variabel Pembeda Permukaan Linear Tubuh
Abstrak: Kampong chicken is the dual purpose of native fowl which used for dual purposes (broiler and layer types). The differentiation of Kampong chicken linear body size calculated with discriminat function analysis, Wald-Anderson and minimum distance D2-Mahalanobis. The location which used for research were Ciamis, Tegal and Blitar. The variables which measured were femur length, tibia length, shank length, shank circumference, wing length, maxilla length and third finger length. T2-Hotelling test show that there were the differentiation of Kampong chicken linear body size on each location. The distinguishing variables between cock of Ciamis and Blitar Kampong chicken were shank length and third finger length; whereas between cock of Tegal and Blitar Kampong chicken was shank length. The distinguishing variables between hen of Ciamis and Tegal Kampong chicken were shank circumference and wing length; between hen of Ciamis and Blitar Kampong chicken was third finger length; and between hen of Tegal and Blitar Kampong chicken were shank lenght and third finger length. Correction factor based on Wald-Anderson criteria between cock of Ciamis and Blitar Kampong chicken was 77,11% dan 77,59% between cock of Tegal and Blitar Kampong chicken. Correction factor between between hen of Ciamis and Tegal Kampong chicken was 71,03%; 66,91% between hen of Ciamis and Blitar Kampong chicken; and 71,01% between hen of Tegal and Blitar Kampong chicken. Minimum distance D2-Mahalanobis between cock of Ciamis and Blitar Kampong chicken was 1,699 and 1,513 between cock of Ciamis and Blitar Kampong chicken. Minimum distance D2-Mahalanobis between hen of Ciamis and Tegal Kampong chicken was 1,072; hen of Ciamis and Blitar Kampong chicken was 1,006; and between hen of Tegal and Blitar Kampong chicken was 1,061

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.
