Judul: Pengetahuan, Sikap, Dan Praktek Pemberian Asi Serta Status Gizi Bayi Usia 4-12 Bulan Di Perdesaan Dan Perkotaan
Abstrak: Exclusive breastfeeding rates in Indonesia is still low. Some studies indicated that low mothers' nutritional knowledge and attitude is the cause of low exclusive breastfeeding practice. The main aim of this study was to compare breastfeeding knowledge, attitude, practice and infants nutritional status between rural and urban areas. In this cross-sectional study, Desa Jayabakti, Kabupaten Sukabumi represents rural area, while Kelurahan Kedung Jaya, Kota Bogor represents urban area. Samples were 31 mothers-infants in each area who were selected by simple cluster sampling method. The differences between two areas were analyzed with the independent t-test, chi-square test, and Fisher's exact test. The correlation between variables were analyzed with rank Spearman. The result of this study showed that mother's knowledge and attitude of nutrition, especially about exclusive breastfeeding, was higher in urban than in rural area. There were differences in mothers' knowledge and attitude between rural and urban areas (p<0.05). Exclusive breastfeeding in rural area practiced by 41.9%, which is higher than in urban area (25.8%). Nevertheless, there was no statistical difference in exclusive breastfeeding practice between rural and urban areas (p>0.05). Breastfeeding practices which statistically difference in rural and urban areas were the introduction of colostrum status and brastfeeding time (p<0.05). Early initiation of breastfeeding was associated with exclusive berastfeeding practice in urban area (p<0.05), but none of the variables were associated with exclusive breastfeeding practice in rural area (p>0.05). Furthermore, exclusive breastfeeding practice was not associated with 4-12 months infants nutritional status (p>0.05). Mothers' family should be targeted as target of audience in breastfeeding promotion.

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.
