Abstrak: The present experiment was conducted to discrimnate the body size and body shape of the Etawah grade goats in different group of age at Daya Mitra Primata (DMP) Cooperative. Forty-seven of Etawah grade goats at DMP Cooperative were used. All Etawah grade goats was grouped according to sex and age. It were consisted of 32 female goats (five heads of I0, six head of I1, seven heads of I2, eleven heads of I3 and three heads of I4) adan 15 female goats (six head of I0, five heads of I1 adn four head of I4).

Abstrak: This study aims to determine the size, shape and characteristics of head on goats in the Cordero, Pelaihari and Doa Anak Yatim Farms. The size and shape of the head is used to distinguish between groups morphometric characteristics of Etawah Grade Does. The variables of head measure is not noticed by the breeder, so goats adapt and have a distinctive appearance. The results of this study can be used as basic morphometric data of Etawah Grade does in Indonesia, and for the conservation. The variables measured were akrokranion-prosthion, basion-prosthion, the length of the lower jaw, head height, tuber facial left-right, nasion-rhinion, entorbitale left-right, euryon left-right dan supraorbitale left-right. The study used 90 data. The data analysis using descriptive, T2-Hotelling statistics and Principal Component Analysis were used to create clusters diagram and dendogram. Akrokranion-prosthion and basion-prosthion became discriminators of Etawah grade does head size in all three farms. Discriminatots of Etawah Grade does head shape on Cordero farm was nasion-rhinion, Pelaihari was head hight and supraorbitale, DAY Farm was euryon left-right. The data of linear measurement classified separated each other. Morphometric data of Etawah Grade does head on Cordero and DAY Farm were different class with Pelaihari.

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.
