Judul: Pendapatan Keluarga, Pengetahuan, Sikap, Konsumsi serta Status Gizi Anak Keluarga Peternak Ikan Lele (Clarias gariepinus)
Abstrak: An adequate nutrition must be consumed by school-age children to fulfill the basic need of nutrients for their progressive growth. Food consumption is influenced by maternal nutrition knowledge and family income. The purpose of this study was to analyze correlation between family income, maternal nutrition knowledge, attitude, and catfish consumption with children nutritional status of farmers family in Parung, Bogor. This research was conducted in June 2012 used cross sectional study. A total number of 31 catfish farmers are purposively selected with inclusive criteria:(1) has fishpond either owned or profit-sharing system, (2) has a primary school children, (3) willing to be interviewed. Primary data consists of family and children characteristics, nutritional knowledge, attitude, catfish consumption and dietary intake. Secondary data is characteristics of a research site. The study showed that there was no correlation between maternal nutritional knowledge, family income and children nutritional status with food consumption, there was no correlation between family income, and children nutritional status with catfish consumption, there was correlation between maternal nutrition knowledge with catfish consumption (p<0.05), and there was no correlation exist between maternal nutrition knowledge and family income with children nutritional status.

Judul: Studi perbandingan pendapatan keluarga, konsumsi pangan dan status gizi anak sekolah pada keluarga nelayan dan petani
Abstrak: Secara umum penelitian bertujuan untuk mengetahui tingkat pendapatan keluarga, konsumsi pangan dan status gizi anak sekolah pada keluarga nelayan dan petani. Secara khusus bertujuan untuk mengetahui keragaan pendapatan keluarga, konsumsi pangan, tingkat konsumsi dan status gizi anak sekolah pada keluarga nelayan dan petani, mengetahui hubungan pengetahuan gizi ibu dan pendapatan keluarga dengan konsumsi pangan serta hubungan konsumsi pangan dengan status gizi anak sekolah. Penelitian dilaksanakan di Desa Teluk dan Desa Banyu Biru Kecamatan Labuan, Kabupaten Pandeglang, Propinsi Bunten dari bulan Juni sampai dengan Agustus 2002. Contoh adalah murid Sekolah Dasar (SD) perempuan maupun laki- laki yang duduk di kelas 1 sampai dengan kelas 5 atau berusia 6 tahun sampai dengan 10 tahun pada keluarga nelayan dan petani, masing-masing keluarga terdiri dari 30 contoh.

Judul: Penggunaan Metode Homotopi untuk Menyelesaikan Persamaan KdV (Korteweg-de Vries)
Abstrak: Natural phenomena can be explained using nonlinear mathematical models. In this paper, we studied the solution of KdV equation using the Homotopy method. The KdV equation is used for describing both surface and internal waves. One of the solutions is called a solitary wave. The use of homotopy method to solve the KdV equation required a nonlinear operator which was determined by the nonlinear form of the KdV equation itself. Based on this operator, a recursive formula was obtained to get a sequence of the KdV solution. The higher the sequence order of the sequence used, the closer to the exact solution of the KdV equation.
