Judul: Hubungan Kepuasan Pelayanan Makanan terhadap Tingkat Kecukupan Pasien Diet Lunak di RS Ummi Bogor
Abstrak: Kepuasan pasien adalah sejauh mana pasien merasa bahwa kebutuhan dan harapannya dipenuhi oleh pelayanan yang diberikan. Tujuan penelitian adalah menganalisis hubungan kepuasan pelayanan makanan terhadap tingkat kecukupan pasien diet lunak yang dirawat di RS Ummi Bogor. Penelitian menggunakan desain studi cross sectional melibatkan 50 subjek. Data karakteristik dan tingkat kepuasan pasien dikumpulkan dengan wawancara menggunakan kuesioner. Hasil penelitian menunjukkan sekitar separuh (54%) subjek menderita PTM, hampir dua per tiga (64%) subjek berstatus gizi normal, dan memiliki tingkat kecukupan gizi yang baik. Asupan makanan subjek laki-laki lebih banyak daripada subjek perempuan. Kepuasan subjek terhadap pelayanan makanan rumah sakit sudah baik dengan rating scale 61-80 %, yang artinya puas. Variabel yang berhubungan signifikan dengan tingkat kepuasan adalah asupan karbohidrat (p=0.015) dan tingkat kecukupan lemak (p=0.046). Penelitian ini menyarankan perlunya peningkatan pelayanan makanan terutama pada indikator rasa, mengingat salah satu alasan subjek tidak menghabiskan makananya adalah karena rasa yang hambar.

Judul: Analysis of the Satisfaction Level with Nutrition Services, Food Waste, and Lost Costs for Inpatients at Al Islam Hospital Bandung
Abstrak: Penelitian ini bertujuan menganalisis sisa makanan, biaya sisa makanan, zat gizi sisa makanan, dan tingkat kepuasan pelayanan gizi pada pasien rawat inap dewasa di Rumah Sakit Al Islam (RSAI) Bandung. Desain penelitian yang digunakan yaitu cross-sectional dengan jumlah subjek 42 subjek. Data tingkat kepuasan diperoleh melalui kuesioner The Acute Care Hospital Foodservice Patient Satisfaction, data sisa makanan diperoleh melalui penimbangan, dan biaya sisa makanan serta zat gizi sisa makanan diperoleh dengan perhitungan. . Penilaian tingkat kepuasan berdasarkan aspek kualitas makanan, pramusaji, dan lingkungan fisik. Hasil menunjukkan bahwa sisa makanan tertinggi diperoleh pada makan pagi (28,7%) dengan menu sayur (30,9%). Besarnya biaya sisa makanan dan zat gizi sisa makanan berbanding lurus dengan banyaknya sisa makanan. Tingkat kepuasan pasien terhadap pelayanan gizi tergolong puas. Tidak terdapat hubungan yang signifikan antara tingkat kepuasan pelayanan gizi dengan sisa makanan dan kehilangan biayanya (p>0,05)., This study aims to analyze food waste, food waste costs, food waste nutrients, and the level of satisfaction with nutritional services for adult inpatients at Al Islam Hospital Bandung. This research used a cross-sectional design with 42 subjects. Satisfaction level data was obtained through The Acute Care Hospital Foodservice Patient Satisfaction Questionnaire, food waste data was obtained through weighing method, and the cost of food waste and food waste nutrients were obtained by calculation. Assessment of satisfaction level based on aspects of food quality, waiters and physical environment. The results showed that the highest food waste was obtained from breakfast (28.7%) with a vegetable menu (30.9%). The highest lost cost of food waste and food waste nutrients is directly proportional to the amount of food waste. The level of patient satisfaction with nutrition services was classified as satisfied. There is no significant association between satisfaction level of nutritional services with food waste and lost costs (p>0.05).

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.
