Judul: Analisis Pencapaian Standar Pelayanan Minimum (SPM) Ketahanan Pangan dan Gizi Kota Tangerang pada Tahun 2011
Abstrak: The objective of this research is to identify the problem of food and nutrition security at Tangerang City and evaluate the achievement of Minimum Service Standards (MSS) in 2011. This is descriptive analysis study. Secondary data which collected within period September to November 2012 and data used were obtained from various offices at the local government of Tangerang City. The indicators used to analyze the achievement of SPM consist of Food Security and Nutrition, including availability of energy and protein per capita, strengthening food reserves, availability of information supply, prices and access to food in the area, price stability and food supply, achieving a score of PPH, food safety supervision and guidance and handling of food-insecure areas. Four out of seven indicators were exceed the minimum service standar, while others hasn’t reach target in 2015. Four indicator which exceed MSS target in 2015 are availability of energy and protein per capita, availability of information supply, prices and access to food in the area, food safety supervision and guidance andhandling of food-insecure areas

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.
