Judul: Identifikasi Pangan Olahan Dan Konsumsinya Melalui Survei Konsumsi Makanan Individu Di Dki Jakarta
Abstrak: Pangan olahan mendominasi asupan harian penduduk di negara maju seperti Amerika Serikat dan Jerman. Di Indonesia, data mengenai jumlah dan kontribusi zat gizi pangan olahan dalam asupan harian belum tersedia secara lengkap. Penelitian ini bertujuan untuk mengidentifikasi jenis dan jumlah konsumsi pangan olahan serta kontribusi zat gizi dalam asupan harian penduduk berdasarkan data Survei Konsumsi Makanan Individu (SKMI) 2014. Jenis pangan dikelompokkan dengan memodifikasi NOVA system menjadi non pangan olahan, pangan olahan antara dan pangan olahan dan kemudian dikategorikan dengan mengacu Peraturan Kepala Badan POM Nomor 26 tahun 2016 tentang Kategori Pangan. Asupan zat gizi dihitung dengan menggunakan Nutrisurvey 2007. Konsumsi pangan olahan penduduk DKI Jakarta adalah sebesar 181.56 g (21.15%). Konsumsi pangan masih didominasi oleh non pangan olahan yaitu sebesar 491.19 g (57.23%) dan pangan olahan antara sebesar 185.48 g (21.61%). Persentase konsumsi pangan olahan dalam konsumsi harian menurun dengan meningkatnya umur individu. Pangan olahan antara menyumbang asupan energi, karbohidrat, protein, lemak, natrium dan sukrosa masing-masing sebesar 29.98%, 22.68%, 16.51%, 53.57%, 68.82% dan 57.68%, sedangkan pangan olahan masing-masing sebesar 17.78%, 18.62%, 17.67%, 13.82%, 23.32% and 31.25%. Hasil analisis regresi linear antara jumlah konsumsi pangan terhadap asupan zat gizi menunjukkan bahwa pangan olahan antara sangat mempengaruhi asupan energi, karbohidrat, lemak, natrium dan sukrosa. Besar pengaruh pangan olahan antara tersebut menunjukkan bahwa industri pangan mempunyai peran penting dalam memproduksi pangan olahan antara yang dapat memberikan asupan gizi yang baik. Di sisi lain, proses pengolahan pangan di rumah tangga maupun di tempat usaha pangan siap saji yang dilakukan terhadap pangan olahan antara juga mempunyai peran penting dalam menentukan asupan zat gizi.

Judul: Analisis KonsumsiPanganPendudukProvinsi DKIJakarta
Abstrak: This study was aimed to assess food consumption of people in DKI Jakarta. The design of this study was cross sectional study. The study which is conduted from analyzing food consumption data of Basic Health Research 2010 collected by a 24-hour recall method. Subject obtained from1626 households with 4964 household members.The result showed that energy consumption average of households stood at 1500 ± 711.48 kkal/cap/day and protein consumption average of households stoodat 50.82 ± 27.1 g/cap/day.Almost all (53.1%) energyadequacy level (TKE) households stood atextreemly leveldeficit category,proteinadequacylevel (TKP) households stood at normal category (47.2%) and desirable dietary pattern (PPH) stood at76.6. Spearman test resultshowed there wasno significant correlation(P>0.05) between maternal education level, number of household memberand food expenditure to householdsTKE and TKP.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
