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: 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

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.
