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: Kajian Perbedaan Ukuran Morfometrik Tubuh Ayam Kampung dan Ayam Pelung serta Ayam Nagrak (Persilangan Ayam Kampung dan Pelung)
Abstrak: This research use a secondary data from Rahmat Mufti. The variables which measured were shank length, tibia length, femur length, shank circumference, third finger length, comb tall, maxilla length and wing length. T2-Hotelling test show that there were the differentiation of kampong, nagrak and pelung male chiken (P<0.01), also were seen in group female chiken between kampong and nagrak chiken and between kampong and pelung chiken (P<0.01). The similarity were seen in group female chiken between nagrak and pelung chiken (P>0.05). Fisher discriminant analysis proved the distinguishing were seen in all variables between male group of kampong and nagrak chiken excepted femur length; whereas between male group of kampong and pelung chiken the distinguishing seen in all variables accepted shank femur length. The distinguishing variables between male group of nagrak and pelung chicken were maxilla length. The distinguishing seen in all variables between female group of kampong and nagrak chiken excepted femur length and maxilla length; whereas between female group of kampong and pelung chiken the distinguishing seen in all variables accepted shank length and femur length. The distinguishing variables were unseen between female group of nagrak and pelung chicken. Correction factor based on Wald-Anderson criteria was 100% in group male chikens beetwen kampong and nagrak, and also beetwen kampong and pelung. Correction factor based on Wald-Anderson criteria beetwen nagrak and pelung male chikens was 82%. Correction factor based on Wald-Anderson criteria in all group female chikens was 100% excepted beetwen nagrak and pelung.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
