Judul: Pola Konsumsi Pangan Hewani dan Status Gizi Remaja SMA dengan status Sosial Ekonomi Berbeda di Bogor.
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. The special functions of protein are to build up, keep up, and replace the body cells and tissues. Food derived from an animal is a good protein source in quantity and quality. Food intake, especially protein intake is influenced by social economy factors, including income, education, and occupation. The aim of this research was to analyze the correlation between food derived from an animal consumption and nutritional status of senior high school adolescents in a different social economy status. A cross sectional study design was applied in this research. The research was implemented at two senior high school which have a different social economy characteristic. SMAN 2 Bogor was selected to represent adolesents at urban areas who have higher social economy status and SMAN 1 Ciampea for lower social economy status which located at rural areas. 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). Protein of food derived from an animal consumption of adolesents in SMAN 2 Bogor was higher than adolesents in SMAN 1 Ciampea.

Judul: Analisis Konsumsi Pangan Hewani, Tingkat Pemenuhan Gizi, dan  Status Gizi Siswa SD di Cijeruk, Bogor
Abstrak: Konsumsi pangan hewani yang banyak mengandung protein, vitamin dan mineral masih tergolong rendah terutama pada siswa sekolah dan remaja. Penelitian ini bertujuan untuk menganalisis konsumsi pangan hewani, tingkat pemenuhan gizi dan status gizi siswa sekolah dasar di Cijeruk, Kabupaten Bogor. Desain penelitian cross-sectional study dengan data sekunder pada 915 siswa dari 16 SD di Cijeruk, Kabupaten Bogor pada tahun 2019. Data konsumsi pangan terutama pangan hewani melalui food recall 3×24 jam, tingkat pemenuhan gizi dihitung berdasarkan perbandingan total asupan harian dengan kebutuhan siswa tiap individu, dan status gizi diperoleh dari data antropometri dan kadar hemoglobin siswa. Hasil penelitian menunjukkan konsumsi pangan hewani siswa belum sesuai dengan anjuran pedoman gizi seimbang. Tingkat pemenuhan gizi siswa tergolong defisit kecuali zat besi. Sebagian besar siswa berstatus gizi baik, namun masih terdapat siswa yang tergolong gizi lebih (5,7%) dan obesitas (6,7%), serta 77,9% siswa mengalami anemia dengan tingkat keparahan yang berbeda-beda. Hasil uji statistik menunjukkan kontribusi gizi dari pangan hewani berhubungan signifikan positif dengan pemenuhan gizi, sedangkan kontribusi energi, protein, dan lemak dari pangan hewani memiliki hubungan signifikan negatif dengan status gizi (IMT/U), serta terdapat hubungan signifikan negatif antara kontribusi energi, protein, lemak, dan vitamin B9 dari pangan hewani dengan kadar hemoglobin (p<0,05)., Animal protein consumption that contain lots of protein, vitamins, minerals is still relatively less, especially in school-age children and adolescents. This study aimed to analyze animal protein consumption, nutrient adequacy level, and nutritional status of elementary school students in Cijeruk, Bogor. The research design was cross-sectional study with secondary data on 915 subject from 16 elementary schools in Cijeruk, Bogor in 2019. Animal protein consumption’s were collected by 3×24 hours, nutrient adequacy level were calculated based on student’s nutrient requirements, nutritional status were collected from anthropometry’s data and student’s hemoglobin levels. The results showed student’s animal protein consumption is not accordance with recommended balanced nutrition guidelines. Student’s adequacy level of macro and micro nutrient were classified as deficit except iron. Most of students had good nutritional status, but still had students who classified overweight (5,7%) and obese (6,7%). 77,9% students have anemia with different severity. Correlation test showed contribution nutrients from animal protein foods was significantly positive with nutrient adequacy, while contribution of energy, protein, and fat from animal protein foods was significantly negative with nutritional status (BMI/A), and there was negative correlation between contribution of energy, protein, fat, and vitamin B9 from animal protein foods with hemoglobin levels (p<0,05).

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.
