Abstract

The research is aimed at designing a decision-making system for the determination of credit using the Analytical Hierarchy Process (AHP). Determining the provision of credit is still done manually so it takes a long time for data processing, as well as the assessment made by the leadership in determining the feasibility of the loan is still subjective. The research design used is a structured Unified Modeling Language (UML) that consists of the design of model use case diagrams, activity diagrams, sequence diagrams, and class diagrams, while programming languages use PHP, JavaScript, and MySql for database processing. The method used in obtaining results is Analytical Hierarchy Process (AHP). The result of the design of the decision-making system for the determination of credit using the Analytical Hierarchy Process (AHP), among others, provides the calculation of the expansion of credit and can provide a credit feasibility report for the customer who has filed.

Abstract

This study aims to determine the level of beef demand, the factors that affect beef demand and measure and identify the role of the elasticity of factors that affect beef demand. Sampling is done by simple random sampling. The data analysis method used is qualitative (descriptive) and quantitative analysis. The results showed that the demand for beef at the household level in Sei Sikambing B village, the average beef consumption was 2.2 kg / month. Simultaneously the test results show that the variable beef prices, fish prices, chicken meat prices, egg prices, the level of household income, the number of family members, and taste have a real impact on the amount of beef demand at a 95% confidence level. On the price of partial fish, the price of chicken cuts, the level of household income and tastes significantly influence the demand for beef at a 95% confidence level, while the variable beef prices, egg prices, and the number of family members do not significantly influence the demand for beef meat at the level 95% confidence. From the estimation that the determination value (R2) of 67.8% variation of the seven variables can explain the amount of beef demand, while the remaining 32.2% is influenced by other variables. Beef demand is not elastic to changes in beef prices.Keywords: Demand, Elasticity, Price, Beef, Income
