Judul: Konsumsi Air Putih, Status Gizi, dan Status Kesehatan Penghuni Panti Werda di Kabupaten Pacitan.
Abstrak: The objective of this study was to learn and analyze the relationship between the consumption of plain water, nutritional status, and health status of panti werda residents in Pacitan. This study used cross-sectional study design. Subject of this study were panti werda residents. As many as 24 people were chosen as subject. Descriptive analysis showed that 75% of subject had plain water sufficient levels were categorized as adequate and 25% were inadequate. Energy and protein sufficiency levels of subject as many as 33% and 42% were categorized as normal. Micronutrient sufficient levels of subject consists of 83% phosphorus, 88% iron, and 100% vitamin A were categorized as adequate, but calcium and vitamin C sufficient levels as many as 96% and 100% were categorized as inadequate. As many as 42% subject had normal nutritional status, 25% were underweight, and 33% were overweight. Health status of subject as many as 54% were categorized as high and 46% were low. The Pearson and Spearman correlation test showed that nutritional status with nutrient intake, plain water consumption, and health status of subject had no significant relationship (p>0.05).

Judul: Bifurkasi Hopf pada Model Siklus Bisnis Kaldor Kalecki tanpa dan dengan Waktu Tunda
Abstrak: Business cycle model is one of dynamical system models in economic. One of the business cycles model is Kaldor-Kalecki model. Kaldor-Kalecki business cycle model that is written in delayed defferential equations, is a business cycle model that involves gross product and capital stock of a company. In this paper Kaldor-Kalecki business cycle model is analyzed using both nondelay and delay in time of capital stock. By Taylor expansion for the time delayed model, an analysis of stability around the fixed points has been done. Furthermore, by using Hopf bifurcation theorem, it can be shown that there exists periodic orbits and limit cycle. In the nondelayed model, changing the parameter of goods market could lead to the occurrence of Hopf bifurcation and the existence of limit cycle. Similarly, for the delayed model, it has been shown that changing the time delay parameter may result in the occurrence of Hopf bifurcation and limit cycle.
