Judul: Karakteristik Konsumsi Pangan Hewani di Berbagai Wilayah Menurut Indikator Kesejahteraan
Abstrak: This study are aim to know about development of characteristic animal food consumption base on welfare indicators. An Ecological design was use in this study. The date of this research is Susenas publication 2009, 2010, and 2011. The result show that share of animal food expenditure in various regions is fluctuation. Share of Animal food expenditure in urban areas more higher than rural. The pattern of animal food expenditure is fish, eggs and milk, meat. Fish, eggs and milk proportion are decrease while the meat increases. Protein contribution of animal food in various regions is increases. Then, the population in urban areas has better protein contribution than rural. Protein adequacy level in various regions is increase continuously. The urban population has a better protein adequacy level than rural. The result of regression test known that the economic and demographic factor has a significant impact on animal food expenditure in various region at 5% level with r = 0.807.

Abstrak: One kind of food which has important role in developing the food security and create human resources who has healthy quality is food animal proteins. The government is targeting food consumption of animal protein as much as 7.2 g/capita/ day in 2014. Food sources of animal protein can be derived from livestock or fishery products like ruminant meat, poultry, fish, eggs, and milk. This study aims to analyze the pattern of household consumption in Bogor Regency, analyze the level of demand elasticity, and perform simulations to analyze the impact of higher prices for meat. The data used comes from SUSENAS 2012 with 1125 households in Bogor Regency. The analytical method used was descriptive analysis and model of Almost Ideal Demand System (AIDS). The analysis showed that the type of ruminant meat consumption group was very inelastic and have a lower level of consumption than other animal protein foods. People in Bogor Regency consume more fish than ruminant meat. Increasing the prices of beef could make other public consumption for food source of animal proteins is down. Food protein consumption for the people of Bogor regency have met the target set by the government

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.
