Abstract

Investment is the activity of placing capital with the aim of obtaining profits in a certain period; in this case, the Indramayu Regency government will build a market building for investment and provide a place for traders. This study aims to determine the sensitivity of investment value to annual benefits. Data obtained from interviews with the head of market management and related parties. The research method used is the descriptive analysis method using sensitivity analysis with two alternatives. Alternatives are arranged based on the investment value and operational period, namely alternative A with a capital of Rp. 39,782,240,911 and an investment period of 20 years, an interest rate of 12%, and alternative B with a capital of Rp. 42,067,040,911 and an investment period of 25 years, an interest rate of 12%. Based on the results of the analysis and discussion, it can be concluded that alternative A has several investment parameter values, namely NPV 43,960,356,295, BCR (Benefit Cost Ratio) 1.10%, IRR (Internal Rate of Return) 2.73%, and Payback Period (PBP) in year 11, while in alternative B, the value of several parameters, namely NPV 50,056,649,833, BCR 1.53%, IRR 15.63%, and PBP, occurs in year 11. The results of the analysis of the investment value of the annual benefit of each alternative are sensitivity A at Rp. 48,459,760,321, and sensitivity B at Rp. 53,277,732,244.

Abstract

Structural damage often occurs in buildings due to earthquake loads. Irregular buildings have a greater risk of damage due to earthquakes than regular buildings. Because the probability of an earthquake occurring in a structure cannot be predicted, an analysis is needed that can describe the vulnerability or fragility due to earthquakes. The purpose of this study was to determine the performance of irregular buildings and the probability of building damage based on seismic fragility. The method used to compile the seismic fragility curve is HAZUS, while the structural performance is obtained from the pushover analysis. Hazus is a method for estimating losses due to disasters, while the pushover analysis is in the form of a push-load application on the structure. Based on the results of the analysis, the structural performance point was obtained with a base shear force and displacement in the x direction of 4194.424 kN and 0.145 m, while in the y direction it was 4187.2016 kN and 0.152 m. The performance level of the building structure based on the analysis results is stated in the Damage Control (DC) condition according to ATC-40 and Life Safety (LS) according to FEMA 440. Based on the fragility curve, the probability of ultimate damage and yield conditions in moderate criteria and the probability of damage in the x and y directions of the building is 100%. The results of this study provide important information about the condition of irregular building structures during an earthquake so that it can be used for structural evaluation and mitigation during an earthquake.
