Judul: Analisis Permintaan Dan Penawaran Domestik Daging Sapi Indonesia  Skripsi
Abstrak: The aims of this research were: 1) to know the factors that determine beef demand in Indonesia 2) to know the factors that determine beef supply in Indonesia 3) to know beef demand and supply elasticity in Indonesia. The time series data in the periods for 15 years of 1990-2005 was used for this research from Badan Pusat Statistic. A dynamic model of Ordinary Least Square (OLS) method was used to analyze the data using Microsoft excel 2003 and Eview 4.1. The factors that determine beef demand and supply describe by quantitative description. This research held on June until September 2008. This research resulted several outputs: 1) Beef demand can be explained by its free variable which is beef domestic price, fish price, income per capita, and human population with each coefficient value – 4.4, 4.9, 36.4, and 1.8 and do not have problem with econometric test, statistic test, and economic test, 2) Beef supply can be explained by beef domestic price, domestic beef production, cattle price, and domestic cattle population with each coefficient value 2.8, 0.9, - 8.7, 0.04 and do not have problem with econometric test, statistic test, and economic test Key words : demand, supply, beef, elasticity

Judul: Analisis Faktor-faktor yang Memengaruhi Permintaan Daging Sapi dan Implikasinya terhadap Kebijakan Impor
Abstrak: Chaotic imported beef in November 2012, resulting in a rise in the price of beef in the market so that the need for special handling so that beef prices. This research was conducted to analyze the factors that affect the demand for beef in Indonesia and the role of substitution, and the implications of policy import. This study uses secondary data the period 1982-2011. Analyses were performed with the econometric approach, estimation models using Principal Component Regression (RKU). The results show the coefficient of determination (R2) of 71.7 percent, and the elasticity of each of the variables tested small relative to the demand for beef show that beef consumption is not replaceable. Beef demand continues to increase every year even though the price of beef is relatively expensive. Formulations stabilization policy covering the prices of additional supplies at the time of the great religious, imports done merely to meet national shortage of supplies beef and ensure the availability of food -substitutions beef as the availability of chicken meat and eggs, and increases the production of beef in the long run.

Judul: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
