The design of this study was coss sectional. The number of samples was 30 hospitalized patients whose consumption was observed for 3 days. samples were selected purposively in hospitals in Bogor and Jakarta. Statistical analysis using Mann Whitney test, pearson correlation regression, and stepwise regression using Microsoft Excel and Minitab. The results showed that there was a relationship between age, nutritional status, blood pressure, and body temperature with the type of disease.

Abstract

ABC Egg Agents ability to develop its business activities cannot be separated from the purchasing power of consumers to buy eggs of the appropriate quality and quantity. In the business of selling chicken eggs, the factors that can increase profit are eggs' selling price. One of the reasons for fluctuating sales conditions at egg agents is the selling price is too high, resulting in a decline in sales. The results of hypothesis testing show the acceptance of Hypothesis one, which offers a relationship between the selling price and the demand for eggs. Increasing selling prices can affect the market because the value of determination (R2) is above 80%, which is 91.7% which describes a solid negative relationship. This condition shows that if the price increases, the demand will decrease. This condition indicates that the Egg Agent must manage the selling price properly to increase the demand.

Abstract

The Stock buildup problem has led to an increase in product rejects at PT Marina. This condition is caused because the company cannot identify fluctuating demand conditions and only focuses on Customer Orders. Based on this problem, an analysis was carried out regarding demand using the Multiplicative decomposition forecasting technique. The company has three seasons in the demand for glass bottled water products. Based on the demand forecasting analysis results, the demand regression model is demand (y) = 153052 + 139.88 period (x). Based on the regression results, the demand forecast results are 159,819 boxes. The results of production schedules are based on the results of demand forecasting, so the Stock condition in the company is obtained, namely 3430 - 4760 boxes/week, and this condition is the optimal condition because it is below the maximum product inventory capacity in the company.
