Judul: Analisis Situasi Ketahanan Pangan dan Gizi Kota Tangerang Periode Tahun 2008-2011
Abstrak: The study is aimed to analyze food and nutrition security of Tangerang City consisted of food supply, distribution, consumption, and nutritional status during the period of 2008-2011.In common, Tangerang City food supply equal to energy in the period of 2008-2011 was fulfill the WNPG recommended dietary allowance, however its decrease in the latest year. Despite of no food storage held by the local government of Tangerang City yet, BULOG Sub Divre Tangerang manage government rice stock that can be used by local government whenever needed to be released in the market during rice shortage. In general food distribution in Tangerang city is stable as indicated by low coefficient of variance of desicable food price. Quality of food consumption is remained a serious problem since the dietary pattern score (PPH score) in 2011 was only 77.3 and energy adequacy level 97.70%. Local government survey found that 33.3 % of selected food marketed were not comply the regulation regarding uses of hazardous subtances added to food such as borax, formalin and textile colorant. Under nutrition prevalence reach 12.6% which was lower than MDG’s target of 18.5% in 2015, but in some villages under nutrition are still prevalent an the prevalence was higher than MDG’s target

Judul: Analisis Situasi Ketahanan Pangan serta Hubungannya dengan Prevalensi Stunting di Provinsi Banten
Abstrak: Penelitian ini bertujuan menganalisis situasi ketahanan pangan serta menganalisis hubungannya dengan prevalensi stunting di Provinsi Banten. Data yang digunakan yaitu data sekunder dengan unit analisis 8 kabupaten/kota di Provinsi Banten tahun 2017 dan 2018. Tingkat ketersediaan energi dan protein tidak memenuhi Standar Pelayanan Minimal (SPM) (<90%) dan skor Pola Pangan Harapan (PPH) ketersediaan tidak memenuhi skor ideal (<100). Tingkat kemiskinan lebih tinggi dari target. Proporsi persentase pengeluaran pangan per kapita penduduk lebih besar daripada pengeluaran non pangan. Tingkat kecukupan energi dan protein sudah memenuhi SPM (>90%). Namun, skor PPH konsumsi belum memenuhi skor ideal (<100). Rata-rata lama sekolah perempuan yaitu setara dengan SMP. Angka Harapan Hidup (AHH) lebih rendah dari skor nasional (<71 tahun). Prevalensi stunting tahun 2017 tergolong tinggi (>29%) sedangkan pada tahun 2018 tergolong rendah (≤29%). Terdapat hubungan signifikan searah (p<0.05) antara tingkat ketersediaan energi dan protein, skor PPH ketersediaan, tingkat kemiskinan, dan pengeluaran pangan per kapita dengan prevalensi stunting. Terdapat hubungan signifikan yang tidak searah (p<0,05) antara tingkat kecukupan protein, skor PPH konsumsi, rata-rata lama sekolah perempuan, dan AHH dengan prevalensi stunting. Terdapat hubungan tidak signifikan (p>0,05) antara tingkat kecukupan energi dengan prevalensi stunting.

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.
