Abstrak: The general objective of this study were to assess food service management, food acceptance, and the consumption’s level of students boarding school dormitory SMA 1 Pemali Bangka Belitung. The research was conducted in May-July 2013 with a cross sectional design. Subjects was purposively chosen with the total of 71 students. A total of51.0% criticalcomponent of food service management the have implemented which consists ofplanning, purchasing, storing, processing, servicing,personal hygiene, andsanitation.Spearman correlation analysis showed that the preference level for taste of food was significantly associated (p<0.05)withenergy and protein sufficiency level. The preference level for temperature of food was significantly associated(p<0.05) with sufficiency levels of phosphorus. Preference level for temperature of food was significantly associated (p<0.05)with compliance level of energy and iron. The level of compliance was significantly associated (p<0.05)with sufficiency level of energy, iron, phosphorus, and zinc. Energy, protein, fosfor, iron intake from dormitory was significantly negatively associated(p<0.05) with intake from non dormitory.

Judul: Analisis Sistem Penyelenggaraan Makanan, Ketersediaan Energi Dan Zat Gizi Serta Daya Terima Menu Asrama Sekolah Smart Ekselensia Indonesia, Parung, Bogor
Abstrak: Adolescence is the second fastest growing period after the childhood. Energy & nutrients requirement tends to increase sharply in late adolescence. The purpose of this research is to examine foodservice management, energy and nutrients availability level, and menu acceptance. The research is conducted in Smart Ekselensia Indonesia schools (Senior High School), Bogor, West Java. The cross-sectional design was apllied and 56 sample was selected based on inclusion criteria i.e. fourth or fifth grade, male, and age 16—18 years old. The result show that foodservice system of SEI school is fairly good, but the menu planning of this school was not based on student’s nutrients requirement. Application of food service hygiene and sanitation guidance from Ministry of Healthy Regulation 1096/MENKES/PER/VI/2011 in SEI school was 71% while application of foodhandlers personal hygiene was 94.6%. The availibility level of Vitamin A and Iron has met (100%) its requirement. Meanwhile, the availibility level of energy and nutrients are as follows: energy 92,4%, protein 98,8%, vitamin B 72.6%, vitamin C 62.7%, calsium 81.2%, and phosphorus 97%. The avaibility level of carbohydrate and fat were repectively 53.3% and 23.8% compare to recommendation. Regarding colour, shape, aroma, taste, and consistency aspect of menu, the menu acceptability of responden was concominant with left over of food that can be used as indicator of acceptability of a menu.

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.
