Hasil penelitian menunjukkan bahwa proporsi konsumsi protein hewani didominasi komoditas Ikan, elastisitas harga sendiri mempunyai tanda positif untuk semua komoditas, hal ini mengindikasikan bahwa semua komoditas bersifat inelastis terhadap permintaan yakni perubahan permintaan lebih kecil dari perubahan harga. Elastisitas harga silang bernilai lebih dari 0, mengindikasikan bahwa antar komoditas pangan berhubungan saling menggantikan (substitusi). Elastisitas pendapatan untuk komoditas Daging bernilai lebih dari 1, hal ini mengindikasikan bahwa Daging termasuk barang mewah, sedangkan komoditas Telur dan Ikan termasuk barang normal atau pokok sehari-hari (bernilai diantara 0 dan 1). ......This thesis is intended to get information about consumption pattern and household expenditures from animal protein source food especially fish product, furthermore used as indicator for household prosperity level in South Sumatera Province using Model LA/AIDS. This Model AIDS used to find out consumption pattern one commodity, correlation with its own price, correlation with other commodity prices, household leader income, location, household leader job, and household poor status. This research took random data sample as many as 400 unit from population South Sumatera Province, using Survei Sosial Ekonomi Nasional (Susenas) 2010 by Badan Pusat Statistika (BPS), with data and publication from Direktori Pengembangan Konsumsi Pangan 2013 by Badan Ketahanan Pangan Kementerian Pertanian, and supported with other publications from related institutions such as Kementerian Kelautan dan Perikanan, Kementerian Perdagangan. Indicated parameter seen from Price Elasticity of Demand, Cross Elasticity of Demand, and Income Elasticity of Demand toward animal protein food demand which grouped into three categories, Meat, Egg and Fish product, using model econometric LA/AIDS.
The result shows that animal protein consumption proportion dominated by Fish product, Price Elasticity of Demand has positive results for all commodities indicating that quality demanded change is smaller than price change. Cross Elasticity of Demand are more than 0 for Meat and Egg commodity compared to Fish product, indicated a substitional relation between food categories. Income Elasticity of Demand for Meat has value more than 1, which shows that Meat is categorized as luxury goods, meanwhile Egg and Food product are categorized as normal or necessities goods.
