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: Home care is a service system which is used to overcome problems arising from the increasing number of elderly population, such as malnutrition. The purpose of this study was to identify food consumption, health status, depression level and nutritional status of elderly participants and non participants Home Care, as well as to analyze the relationship. A cross sectional study was conducted on elderly people aged 60 years and above in Tegal Alur, West Jakarta. A total of 60 elderly (30 participant and 30 non participants) were actively followed as participants. They were interviewed on demography and social economic status, one-month semi-quantitative food frequency questionnaire, health status, geriatric depression scale (GDS) short version, and assessed by anthropometric measures. Average level of adequacy energy, protein, calcium, phosphorus dan vitamin C of participant relatively lower than non participants (87,5% vs 95,5%; 80% vs 90%; 51,4% vs 59,2%; 104% vs 116,1% and 73,1% vs74,9%, respectively). The study showed that no significant difference in term food consumption, health status, depression level, and nutritional status between the elderly participant vs non participants. And as much as 63,3 % participant and 53,3% non participants experienced more than one type of health complaince and most of them are well nourished and not depressed. The statistical analysis with correlation test showed that health status of elderly significantly positive with the level of depression. While other variables such as duration of illness significantly negative with level of adequacy of energy, protein, minerals, and nutritional status. Percent RDA of energy, protein and minerals are positively associated with nutritional status.

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.
