Judul: Hubungan Asupan Serat Dan Konsumsi Pangan Dengan Status Gizi Dan Kesehatan Lansia Penghuni Panti Werdha Bogor
Abstrak: Tujuan penelitian ini adalah mengetahui hubungan asupan serat, konsumsi pangan, dengan status kesehatan dan status gizi pada lansia di Panti Tresna Werdha Bogor. Penelitian menggunakan desain cross-sectional study dengan subjek berjumlah 32 responden. Hasil analisis secara deskriptif menunjukan bahwa tingkat kecukupan energi dan protein sebanyak 82.5% belum memenuhi 100% dari AKG yang dianjurkan. Asupan serat sebagian besar responden sebanyak 71.9% sebesar ≤6 g/hari. Status gizi rata-rata responden tergolong normal dengan rata-rata IMT sebesar 22.7 kg/m2. Status kesehatan sebagian besar tergolong tinggi dengan prevalensi sebesar 59.4%. Uji korelasi Spearman didapatkan tidak terdapat hubungan yang signifikan (p>0.05) antara asupan serat dengan status kesehatan dan status gizi, serta tingkat kecukupan energi dengan status kesehatan responden. Terdapat hubungan yang signifikan antara status gizi dengan status kesehatan (p<0.05).

Judul: Konsumsi Pangan, Aktivitas Fisik, Status Gizi dan Status Kesehatan Lansia di Panti Sosial Tresna Werdha Salam Sejahtera Bogor
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.
