Judul: Pengembangan "Snack Bar" Tinggi Kalori dari Tepung Komposit Sukun (Arthocarpus altilis) dan Kacang Hijau (Phaseolus radiatus linn) untuk Pangan Darurat Anak Balita
Abstrak: Dengan semakin seringnya terjadi bencana alam di Indonesia, maka ketersediaan pangan darurat untuk membantu para korban di lokasi bencana menjadi sangat penting mendesak. Hingga saat ini, belum ada makanan darurat khusus anak balita. Tujuan dari penelitian ini adalah untuk mengembangkan snack bar berenergi tinggi sebagai makanan darurat dari sukun (arthocarpus altilis) dan kacang hijau (phaseolus radiatus linn) tepung komposit untuk anak dibawah lima tahun. Eksperimental desain yang digunakan dalam penelitian ini. Tepung komposit terbuat dari 60% sukun dan 40% kacang hijau digunakan sebagai bahan utama. Snack bar dibuat dengan cara dicampur tepung komposit dan tepung terigu dengan perbandingan 0:100, 25:75, 50:50, 75:25 dan 100:0. Uji organoleptik dilakukan untuk mengukur rasa, warna, aroma, tekstur dan karakteristik produk secara keseluruhan. Jumlah tepung komposit berpengaruh nyata (p<0,05) terhadap warna, aroma, tekstur dan karakteristik produk secara keseluruhan, namun tidak berpengaruh terhadap cita rasa bar makanan ringan. Snack bar dengan perbandingan 75:25 menjadi produk terpilih untuk tersebut studi berikutnya. Energi produk ini lebih tinggi dibandingkan produk komersial. Ini formula mengandung 498 kkal/100 g snack bar. Untuk memasok 30% energi yang cukup anak-anak sebaiknya mengonsumsi 3 buah snack bar.

Judul: Formulasi Sagon dari Tepung Komposit Berbasis Sukun (Arthocarpus altilis) sebagai Alternatif Pangan Darurat untuk Anak
Abstrak: Children are the most vulnerable to malnutrition after natural disasters . The purpose of this research was to develop sagon product based on composite flour of breadfruit (Arthocarpus altilis) as an alternative to emergency food for children. Emergency food product was developed from Indonesia traditional food with increased protein and minerals content. The design used in this study was a complete randomized design with factors such as the types of formula. The results showed that the types of formula were not significantly affect in the organoleptic properties and chemical properties of the product (p>0.05). Water and fat content of the product is low enough so that it can extend the shelf life of the product. Sagon can be considered as a high-energy food, Ca, Fe, Zn, dietary fiber as well as a source of protein. Nutritional need of child at snack time can be met by consuming 2.5—5 sachets per day. Sagon product is acceptable with acceptance rate of 86%.

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.
