Judul: Pola Aktivitas, Konsumsi Pangan, Status Gizi  Dan Kesehatan Anak Jalanan Di Kota Bandung
Abstrak: The general objective of this research was to know and analyze the correlation of pattern activity, food consumption, nutritional status and health of street children. The research design was cross sectional study. This research was part of project research Socio-economics and Environmental Factors Contributing to The Health and Nutritional Status of Street Children. Data was collected on February 2009 in Bandung, West Java. Street children was chosen by purposive sampling from eight NGOs in Bandung. Street children criteria were: 1) 5-18 years old 2) boys and girls 3) spend time in the street at least four hours in a day 4) work for a living in the street, commonly work as singers, beggars, shoe-polisher, porters etc. The result showed that most street children activity was singers, spend 4-8 hours in a day and 4-6 days in a week. The average energy and protein adequacy level of street children was light deficit category, iron and vitamin C in low category and vitamin A in sufficient category. Almost street children have normal nutritional and health status and good personal hygiene. There is no correlation between activity and duration of street children with nutrition adequacy level. There is no correlation between personal hygiene and nutritional status with health status.

Judul: Pola asuh, perilaku keluarga sadar gizi (KADARZI) dan status gizi anak balita di wilayah warung anak sehat (WAS) Kabupaten Sukabumi
Abstrak: The general objective of this study was to study maternal nutritional knowledge, parenting pattern of healthy lifestyle and eating behavior, family’s nutritional behavior awarness (KADARZI), and nutritional status of children under five participants of the Healthy Kids Kiosk (Warung anak sehat=WAS) in Sukabumi District. The cross-sectional study design was used in this study that was conducted in five subdistricts of Sukabumi District i.e. Cicurug, Cisaat, Kadudampit, Kebon Pedes, and Warung Kiara on June to October 2011. The subjects in this study were chosen base on on inclusion criteria, i.e. children 1 to 5 years old, stay near by and having access to Healthy Kids Kiosk (WAS). Respondents of this study were the mothers of children under five who were choses as the subject of research. The number of samples in the study was as many as 79 children. The primary data was included the family characteristics, toddler’s characteristics, nutritional knowledge of toddler’s mother, parenting pattern of healthy lifestyle and eating behavior , consumption and KADARZI behavior and anthropometric. The consumption behavior data was collected by Food Frequency Questionair(FFQ). The results show the nutrition knowledge of mothers are good , meanwhile, healthy lifestyle and eating behavior of parenting pattern is fairly good. Mostly, KADARZI behavior is good, but the frequency of vegetables and fruits consumption is low. Availability of health facilities to support sanitation and higine in the family is fairly good. Meanwhile, we found a lack of availability of sewage disposal facilities (SPAL) since only 55.7% having SPAL. The nutritional status of children underfive was mostly normal, but still, there are undernutrition toddlers, i.e. 46.8% stunting (according to height/age index) and and 6.3% underweight (according to wight/age index). The parenting pattern of eating behavior was significantly correlated with Kadarzi behavior (p<0.01). The healthy behavior was significantly correlated (p<0.01) with parenting pattern, environment condition, and healthy status.

Judul: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
