Abstrak: RETTHA APRILIAN. Food derived from an Animal Consumption Patterns and Nutritional Status of Senior High School Adolescents in a Different Social Economy Status in Bogor. Supervised by HADI RIYADI and YAYAT HERYATNO. Adolescence is an important phase of human growing and maturing. Protein is one of nutrient substance which has special function in growing process that can’t be replace by the other nutrient substance.

Sample was chosen by stratified random sampling which consists of 120 adolescents. Descriptive analytic was carried out to all variables followed by bivariate test using Spearman correlation and Pearson correlation. Independent-sample T test was used to compare means between two data sample. The conclusion of this research showed the difference pattern of food derived from an animal consumption between senior high school adolescents at urban areas (SMAN 2 Bogor) and senior high school adolescents at rural areas (SMAN 1 Ciampea).

Correlation was analyzed by Pearson correlation and significant at the 0.05 level. SMA Negeri 3 Bogor’s location in the middle of city that has much public facilities and some shopping area in Bogor, had complete facility at school, allowed bringing their laptop and also smart phone. SMA Negeri 1 Leuwiliang far from public facilities and shopping area, located at rural, school has good facility but not same as SMA Negeri 3 Bogor’s facilities and not allowed to bring their gadget. Family size correlated with where they live in and 15% family size from adolescent samples that live at rural is a big family. Father’s income correlated with where they live in, father’s income from adolescent samples that live around the city is more than five million per month (37.5%), occupied as an official employee and had high education. Father’s income from adolescent samples that live around the rural is one to three million per month (47.5%), occupied as a trader and had education until high school’s graduate. Mother’s from adolescent samples 56.3% is a housewife. Mother’s who work, occupied as an official employee (30%) and occupied as a trader (11.3%) for the next. Mother’s education correlated with where they live in and mother’s education from adolescent samples that live around the city 70% was graduates from university and than mother’s education from adolescent samples that live around the rural 35% was graduates from high school. Adolescent samples who live around the city had better food habit than adolescent samples who live at rural (r=0.425, P=0.000). Adolescent samples who live around the city have better nutritional education than adolescent samples who live at rural (r=0.252, P=0.001). x Adolescent samples had a positive perception about their body image (75%).

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.
