Data collected through questionnaires and interviews 2x24 hour recall method. There was a significant difference between pretest and posttest knowledge, attitude of nutrition and food safety knowledge (p<0.05), however there was no difference exist between snacks practices pretest and posttest. Snack food contributed energy (13,0%), protein (45,3%), vitamin A (1,4%), vitamin C (15,0%), calcium (5,3%), phosphorus (3,1%) and iron (15,9%) respectively. Street food contributed to the adequacy level of energy (9,0%), protein (55,9%), vitamin A (4,1% ), vitamin C (3,6%), calcium (1,8%), phosphorus (2,1%) and iron (9,5%) respectively.

Abstrak: Makanan jajanan merupakan bagian yang tidak dapat terpisahkan dengan anak sekolah. Penelitian ini bertujuan mengetahui hubungan antara pengetahuan, sikap dan praktik gizi dengan frekuensi jajan anak sekolah dasar di Kota Tangerang Selatan. Desain penelitian berupa cross-sectional study dengan 105 subjek penelitian. Data meliputi karateristik contoh, karakteristik keluarga, pengetahuan, sikap dan praktik gizi, serta frekuensi jajan. Sebagian besar pengetahuan dan sikap gizi contoh tergolong sedang (52.4%) dan baik (59%), hanya saja praktik gizi sebagian besar (41%) tergolong kurang.

Judul: : Persamaan Tunggal sebagai Representasi Kurva Komposit
Abstrak: A mathematical method is introduced to represent a composite curve based on an extension of analytic geometry. The representation is given either with a single equation or with two equations, in the case of parametric representation. This method permits the representation of composite curves in similar manner to the conventional representation of non-composite curves. Some mathematical tools, including Heaviside unit step function and periodizer function, are used in the establishment of a single equation. In this paper, regular equations of regular and irregular polygon, as well as composite curves of two dimensions, are implemented using a computer algebraic system, Mathematica.
