Operations Research: International Conference Series (ORICS) is published 4 times a year and is the flagship journal of the Indonesian Operational Research Association (IORA). It is the aim of ORICS to present papers which cover the theory, practice, history or methodology of OR. However, since OR is primarily an applied science, it is a major objective of the journal to attract and publish accounts of good, practical case studies. Consequently, papers illustrating applications of OR to real problems are especially welcome. In real applications of OR: forecasting, inventory, investment, location, logistics, maintenance, marketing, packing, purchasing, production, project management, reliability and scheduling. In a wide variety of environments: community OR, education, energy, finance, government, health services, manufacturing industries, mining, sports, and transportation. In technical approaches: decision support systems, expert systems, heuristics, networks, mathematical programming, multicriteria decision methods, problems structuring methods, queues, and simulation.

Abstract

This article discusses the use of the Black-Scholes model to calculate the price of agricultural insurance premiums based on the rainfall index. The Black-Scholes model is one of the models used to determine option prices. The research method used is studying the material through mathematics books and journals and collecting secondary data. The data used in this study are rainfall data and rice production data in Magelang City from 2019 to 2020. Based on the results and discussion, the quarterly rainfall data that has a strong correlation are quarterly rainfall one and three. For the reference size with the latest rainfall data (319.5 mm) the premium obtained is IDR 3,557,321.00 per hectare, while for the reference size with the average rainfall data (1094,725 mm) the premium obtained is IDR 623,387. ,00 per hectare.

Cooperatives have financial reports that are reported within a certain period of time with the users of the report themselves being members of the cooperative, management, supervisors and other stakeholders. A balance sheet is a financial report that must be made to report the assets or liabilities of a company/organization. With this balance sheet, a company or organization can find out how much wealth or total net assets it has. The preparation of the financial balance report has 3 stages, the preparation stage, the stage for preparing the balance sheet and the preparation stage.

Abstract

Many company owners are still confused about calculating pensions for their employees so that company owners cannot prepare pensions properly. In this discussion, we will discuss the problem of calculating the total actuarial obligations and normal costs that are part of the pension fund. The purpose of this discussion is to show the solution to the problem of how to find total liabilities using the ordinary credit unit method and to find normal costs using the projected credit unit method. The calculation of total actuarial liabilities uses the credit unit method, while the normal cost calculation discussed uses the projected unit credit actuarial cost method. From the problems discussed, the total actuarial liability on 1/1/95 was IDR 405,335,428 and the normal cost for 1994 on 1/1/94 was IDR 1,071,429. The purpose of this discussion is to help readers better understand how to complete the calculation of total actuarial obligations and normal costs and can be a reference for readers in determining the amount of costs prepared for pensions.

Abstract

Stocks are one of the best-known forms of investment and are still used today. In stock investment, it is necessary to know the movement and risk of loss that may be obtained from the stock investment so that investors can consider the possibility of profit. One way of calculating risk is to use the Expected Shortfall (ES). Because the stock movement is in the form of a time series, a model can be formed to predict the movement of the stock which can then be used for ES calculations using time series analysis. The purpose of the study was to determine the expected shortfall value of BMRI shares using time series analysis. The data used for this research is the daily closing price of shares for three years. In the time series analysis stage, the models used in predicting stock movements are Autoregressive Integrated Moving Average (ARIMA) for the mean model and Generalized Autoregressive Conditional Heteroscedasticity (GARCH) for the volatility model. The average value and variance obtained from the model are then used in calculating the ES on BMRI stock. Based on the results of the study, it was obtained that BMRI's stock had an ES of 0.008116. This means if an investment is made for BMRI shares of IDR 1,000,000.00 for 37 days (5% of 751 days) for an investment period with a 95% confidence level, the expected loss to be borne by the investor is IDR 8,116.00.

Abstract

This study aims to determine the level of farmer participation in the Rice Farming Business Insurance (AUTP) program, and to determine the estimated willingness of farmers to pay the AUTP premium in Karawang Regency and the factors that influence it. The sample in this study amounted to 100 people taken from two villages from two sub-districts, namely Kutapohaci Village in Ciampel District and LemahKarya Village in Tempuran District. Farmers in Karawang Regency are willing to pay the AUTP premium. There are 44% of respondent farmers who are willing to pay the AUTP premium, the average value of the willingness to pay the AUTP premium is IDR 42,480/ha/planting season, which is greater than the value of the AUTP self-help premium set by the current government, which is IDR 36,000/ha/season planting, with a WTP value of IDR 42,480/ha/MT. Farmers hope that there will also be an increase in claim benefits to IDR 7.080.000. Based on multiple regression analysis, the factors that influence the farmer's Willingness to Pay (WTP) value on the AUTP program are the variables of education, land area, land status and income (at the real level). 5 percent). Meanwhile, based on the results of the logit analysis, it is known that the factors that can increase the chances of farmers participating in the AUTP program independently by paying the AUTP premium are the WTP value and income.

Abstract

Everyone certainly wants a welfare in the future, including employees. The company provides a pension program as a form of the company's concern for its employees. This pension fund provides pension benefits to employees at the time of retirement. Funding for this pension requires actuarial calculations which are normal costs and actuarial obligations. This discussion aims to calculate the amount of normal costs and actuarial obligations that must be incurred. The method used in this discussion is the ordinary credit unit method and projecting credit units by analyzing the use of actuarial formulas from several literature studies. In the first discussion using the ordinary credit unit method, the total actuarial liability on 1/1/95 is IDR. 405,355, while in the second discussion using the projecting credit unit method, the normal cost for 1994 on 1/1/94 is IDR 1071, 42. It is hoped that this discussion can increase the reader's knowledge of pension fund mathematics, especially to determine normal costs and also the value of actuarial obligations using the ordinary credit unit method or the projecting credit unit method.
