Judul: Ukuran dan Bentuk Kepala Kambing Peranakan Etawah (PE) Betina Dewasa di Tiga Peternakan.
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: Head’s Size and Shape on Etawah Grade Does at BBPTU-HPT Baturraden and BPTU-HPT Pelaihari.
Abstrak: Kambing Peranakan Etawah (PE) merupakan hasil grading up antara kambing etawah dan kambing kacang yang memiliki sifat dari tetuanya dan merupakan ternak popular di Indonesia. Proses adaptasi di lingkungan geografis berbeda memengaruhi ukuran dan bentuk kepala ternak yang khas dan bersifat mewaris. Penelitian bertujuan melihat respon adaptasi berdasarkan ukuran dan bentuk kepala pada 60 ekor kambing PE betina induk dewasa umur 3 ̶ 4 tahun (kondisi gigi I3) beserta pencirinya menggunakan data sekunder berasal dari BBPTU-HPT Baturraden dan BPTU-HPT Pelaihari. Variabel yang disertakan meliputi akrokranion-prosthion (X1), basion-prosthion (X2), panjang rahang bawah (X3), tinggi kepala (X4), tuber facial kiri-kanan (X5), nation-rhinion (X6), entorbitale kiri-kanan (X7), euryon kiri-kanan (X8) and supraorbitale kiri-kanan (X9). Hasil penelitian dapat menjadi informasi kelengkapan data dasar morfometrik kambing PE di Indonesia untuk pengembangan maupun konservasi. Analisis data menggunakan statistika deskriptif, T2-hotelling, analisis komponen utama. Hasil penelitian menunjukan penciri ukuran dan bentuk kepala kambing PE betina peternakan induk adalah basion- prosthion (X2) dan Panjang rahang bawah (X3). Visualisasi diagram kerumunan menunjukan bahwa kerumunan data Baturraden memiliki skor ukuran kepala lebih besar dengan skor bentuk lebih kecil sedangkan data Pelaihari ditemukan memiliki skor ukuran kepala lebih kecil dengan skor bentuk lebih kecil. Kata kunci: AKU, bentuk, ukuran, peranakan etawah, Etawah-grade goat or kambing peranakan etawah (PE) is the result of grading up between etawah goats and kacang goats that have the inheritance of their parents' trait and is popular livestock in Indonesia. The process of adaption in different geographic environments will affect its head’s size and head’s shape that distinctive and inherited. The purpose of this research is to see the respons of adaptation based on the head’s size and head’s shape of 60 does PE aged 3-4 years (tooth condition I3) and their characteristics used secondary data from BBPTU-HPT Baturraden and BPTU-HPT Pelaihari. Variables included will be akrokranion-prosthion (X1), basion-prosthion (X2), lower jaw length (X3), head height (X4), tuber facial leftright (X5), nation-rhinion (X6), entorbitale left-right (X7), euryon left-right (X8) and supraorbitale left-right (X9). The results of this study can be used as basic vi morphometric data of Etawah Grade does in Indonesia for development and conservation purpose. Data analyzed by descriptive statistics, T2-Hotelling, principal component analysis (PCA). Basion-prosthion became discriminators of Etawah grade does head size while discriminatots of Etawah Grade does head shape was lower jaw length (X3). Scattered diagram visualization of etawah grade does heads showed that Baturraden has bigger size score with smaller shape score and and the opposite occurs in 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.
