Abstrak: The objective of this study was to analyze differences in fiber and liquid intake, physical activity, and symptom of constipation among elderly people lived in government (Sukma Raharja) and non-government (Salam Sejahtera) Elderly Social Institution. This study using crossecsional study design conducted in August until September 2011. The subjects were 61 elderly consist of 30 people from Sukma Raharja and 30 people from Salam Sejahtera. Almost all of elderly (90%) in Sukma Raharja are 60-74 years old, while in Salam Sejahtera 71% are 74-90 years old. All of elderly in Sukma Raharja are women, while in Salam Sejahtera, 51,6% are women. Education background in Salam Sejahtera is higher than in Sukma Raharja and in both groups most of elderly have normal nutritional status. There was significantly (p=0,001) differences in BMI of elderly in Sukma Raharja and Salam Sejahtera. Level of energy (p=0,000), protein (p=0,000), and carbohydrate (p=0,000) adequacy of elderly in Sukma Raharja are significantly higher than elderly in Salam Sejahtera. There was no difference level of fat adequacy (p=0,503), fiber (p=0,925) and liquid intake (p=0,228), and physical activity (p=0,280) in the elderly in two places. There was no significant correlation between fiber intake (p=0,538), liquid intake (p=0,147), and physical activity (p=0,342) with symptom of constipation of elderly.

Abstrak: The objective of this study was to learn and to analyze food consumption, physical activity, nutritional status and health status of the elderly in Panti Sosial Tresna Werdha Salam Sejahtera Bogor. The design of this study used cross sectional study. The number of samples obtained as many as 32 elderly. The results showed that the sufficiency level of energy was normal category, protein was in high category, vitamin A and C were in sufficient category and then Ca and Fe classified as defficient category. The nutritional status of most male sampels was obese-I while female was normal. Most of the sampels physical activities classified as mild. Most diseases for the past 6-12 months on male samples were diabetes melitus and hypertension on female samples. Most of either male or female samples had a lower morbidity score with high health status. The result of Pearson correlation test showed that the energy and nutrients intake had no significant relationship with nutritional status and health status (p >0.05) either nor between physical activity with nutritional status and health status, and nutritional status with health status (p >0.05).

Judul: Real Option Valuation Using Binomial Decision Trees.
Abstrak: A firm that decides to invest has a choice to invest in real assets. A method which is usually used in valuation of the project is discounted cash flow (DCF) method. But, this method can’t be used in projects that account for value of managerial flexibility, such as decision to suspend operations temporarily. Therefore, this kind of project needs to be assessed using real option. Real option valuation can be done in some ways, including the use of path-dependent simulation, as well as closed-form models like Black-Scholes model, partial differential equation, and binomial or multinomial approaches. In this paper, real option valuation using binomial decisions id discussed. Determination of the project value can be done in three steps. First, calculate the expected present value of the project. Next, calculate volatility of the project using Monte Carlo simulation. Last, construct a binomial tree to model the dynamics of the project value using the parameters of the stochastic process, and then add some decision nodes to model the project’s real options.
