Judul: Studi Kandungan dan Persentase Daily Value Asam Lemak Esensial Makanan Indonesia
Abstrak: Essential Fatty Acids play the important role in the development of brain and nervous system, especially at the first thousand days of life. However, current Indonesian food composition table does not include the essential fatty acid contents. This study was aimed to analyze the content of essential fatty acid of Indonesian food consumed by pregnant mothers, lactating mothers and children under five. About 148 Indonesian food was purposive samples from West Sumatra , West Java and South Sulawesi. Analysis of fats were carried out using Soxhlet and Mojonnier and fatty acids using gas chromatography. Fat and linoleic fatty acid content of fat and oil were 92.3 g/100 g and 6475.2 mg/100 g, respectively. Soybean group had the highest value of linolenic fatty acids (362.1 mg/100 g ). EPA and DHA contents of processed fish and shrimp group were 89.5 mg/100 g and 200.7 mg/100 g, respectively. Arachidonic content of processed egg group was 164.7 mg/100 g. Processed fish and shrimp group was categorized as rich source of EPA and DHA (145.1 %).

Judul: Analisis Asupan Lemak dan Asam Lemak Esensial pada Ibu Hamil di Indonesia Berdasarkan Studi Diet Total
Abstrak: Asam lemak esensial merupakan bagian dari PUFA (Polyunsaturated Fatty Acid) yang terdiri dari asam linoleat dan asam alfa linolenat merupakan zat gizi yang dibutuhkan ibu hamil untuk pembentukan jaringan tubuh janin, khususnya otak dan mata. Tujuan penelitian ini adalah menganalisis asupan lemak dan asam lemak esensial pada ibu hamil di Indonesia berdasarkan Studi Diet Total (SDT). Asupan lemak dan asam lemak esensial diperoleh dari data hasil recall individu 24 jam. Kandungan Lemak diperoleh dari Daftar Komposisi Bahan Makanan dan nutrition fact pada makanan kemasan, kandungan asam lemak esensial diperoleh dari komposisi pangan United States Departmen of Agriculture (USDA) dan komposisi asam lemak pangan Indonesia. Total subjek pada penelitian ini adalah 606 ibu hamil. Rata-rata asupan lemak, SFA, PUFA, asam linoleat, asam alfa linolenat dan EPA+DHA berturut-turut sebesar 46±34.5, 18.6±13.5, 17.7±15.5, 5.3±7.3, 0.5±1.0, 0.231.1±848.6 g/hari. Tingkat pemenuhan lemak dan asam lemak esensial pada ibu hamil tergolong defisit berat dengan rata-rata pemenuhan lemak, SFA, PUFA, asam linoleat, asam alfa linolenat, EPA+DHA berturut-turut sebesar 75.5%,76.2%, 119.1% , 106.8%, 38.1%, 76.1%. Hasil uji regresi menunjukkan bahwa subjek di wilayah perdesaan beresiko 1.4 kali lebih besar kekurangan asupan asam linoleat daripada subjek di wilayah perkotaan .

Judul: Bifurkasi Hopf pada Model Siklus Bisnis Kaldor Kalecki tanpa dan dengan Waktu Tunda
Abstrak: Business cycle model is one of dynamical system models in economic. One of the business cycles model is Kaldor-Kalecki model. Kaldor-Kalecki business cycle model that is written in delayed defferential equations, is a business cycle model that involves gross product and capital stock of a company. In this paper Kaldor-Kalecki business cycle model is analyzed using both nondelay and delay in time of capital stock. By Taylor expansion for the time delayed model, an analysis of stability around the fixed points has been done. Furthermore, by using Hopf bifurcation theorem, it can be shown that there exists periodic orbits and limit cycle. In the nondelayed model, changing the parameter of goods market could lead to the occurrence of Hopf bifurcation and the existence of limit cycle. Similarly, for the delayed model, it has been shown that changing the time delay parameter may result in the occurrence of Hopf bifurcation and limit cycle.
