Abstract

The purpose of this research is to get formula to calculate premium reserve value with prospective calculation for education insurance. This study examines the value of premium reserves for people aged 40 years with a coverage period of 17 years. In determining the value of premium reserve using the prospective calculation. It will be started by completing the value of the Indonesian Mortality Table 2011 using the interest rate of 6.5%, calculating the cash value of the benefit, the annuity value, the net annual premium value, and the net monthly premium value. The results of this study indicate that the value of premium reserves with a prospective calculation for benefits paid at the end of the year and the premium reserve value for benefits paid at the time the insured dies, its value with the value of the cash price set by the insurer at the end of year- 17 on the insurance contract.

Abstract

Tourism is one of the main sectors in increasing a country's economy. For this reason, an estimate of tourist visits to Bali is needed so that it can be used as a benchmark for development and development in the tourism sector. Forecasting the number of foreign tourists coming to Bali using the Seasonal ARIMA method produces an MSE value of 1,250,276,526. While the Winter's Exponential Smoothing method obtained 1,291,150,258. The results of the forecast for the number of foreign tourists coming to Bali in 2020 using the SARIMA method are 588,980, 653,740, 659,817 (January-March 2020).

Abstract

The high number of critical illness cases and the rising medical cost affect the number of insurance claimed. It can be a problem for the insurance company in estimating future claim trend to decide the risk premium cost, so that we need a method to solve the problem which is called Empirical Bayes Credibility Theory (EBCT). Based on that information, the goal of this research is estimating the risk premium cost for critical illness cases using EBCT method. In this research, a large simulation of the expected claim data of critical illness policyholders is used, which are grouped by age and gender. In processing data by applying the EBCT method, the credibility factor is determined first, then the size of the risk premium can be estimated, with the calculation results obtained by a different estimate of the risk premium for each age group based on gender.

Abstract

Policy values are funds be held by insurance company that will be used for unexpected claims from insurance participants. The purpose of this work is to calculate constant annual premiums with and without pure endowment on joint life couple insurance, then determine and calculate formula policy values with prospective method. The policy values ??in joint life couple insurance, are affected by premium payments. Policy values ??benefit at the end of the 1st year until the end of the 11th year will increase, because the money received by insurance company from premium payments is more than the sum insured to be paid. Policy values ??benefit at the end of the 11th year until the end of the 66th year will decrease because there are no more premium payments.

Abstract

Endowment insurance provides protection benefit and saving benefits. In the endowment insurance the insured party (insurance participant) must be paid the premiums. In addition to premiums, there is also policy value, which is sum of money that must be collected by the company in preparation for claim payment. The purpose of this study was to determine calculation of policy value in endowment insurance using Illinois method based on Weibull Mortality Law. In this study used secondary data from United States Life Table in the form of mortality probability data. Calculation value using Weibull mortality law, then the policy value calculated by Illinois method. The result of this study is policy value using Illinois Method based on Weibull Mortality Law is bigger than policy value using Illinois method without Weibull mortality law in the first year until year 20th. After year 20th, the policy value using Illinois method based on Weibull mortality law is smaller than policy value using Illinois method without Weibull mortality law, while at the end of the insurance year which is year 30th, the policy value with or without Weibull mortality law generates the same value.

Abstract

Premium refunds are a sum of the money returned to the insured. The purpose of this study was to compare the premium of endowment life insurance with premium refund on constant interest rates numerical calculations and using Monte Carlo simulations. Gompertz distribution was used to obtain the mortality rates. The results showed that the premiums generated by Monte Carlo simulations for insurance participants issued under 45 years will be more expensive than the ones which were generated by numerical calculations. However, the premiums generated by Monte Carlo simulations for insurance participants issued above 45 years will be cheaper than the ones which were generated by numerical calculations.

Abstract

When the returns of stock prices show the existence of autocorrelation and heteroscedasticity, then conditional mean variance models are suitable method to model the behavior of the stocks. In this thesis, the implementation of the conditional mean variance model to the autocorrelated and heteroscedastic return was discussed. The aim of this thesis was to assess the effect of the autocorrelated and heteroscedastic returns to the optimal solution of a portfolio. The margin of four stocks, Fortune Mate Indonesia Tbk (FMII.JK), Bank Permata Tbk (BNLI.JK), Suryamas Dutamakmur Tbk (SMDM.JK) dan Semen Gresik Indonesia Tbk (SMGR.JK) were estimated by GARCH(1,1) model with standard innovations following the standard normal distribution and the t-distribution.  The estimations were used to construct a portfolio. The portfolio optimal was found when the standard innovation used was t-distribution with the standard deviation of 1.4532 and the mean of 0.8023 consisting of 0.9429 (94%) of FMII stock, 0.0473 (5%) of  BNLI stock, 0% of SMDM stock, 1% of  SMGR stock.

Abstract

The aim of this research was to get the formula of premium reserves through the premium sufficiency method. Premium reserve is the amount of fund that is collected by the insurance company in preparation for the claim’s payment. Premium sufficiency method is gross premium calculation. To construct that formula, this research used Tabel Mortalitas Indonesia (TMI) 2011, interest rate 2.5% and cost of alpha %. Based on simulation result in men premium reserve value of age 1 of 56 years propotional with insured periods, but after56 years enhancement of premium reserve value.

Abstract

Profit testing is a method to find out the potential loss or gain of unit link life insurance product. Unit-link life insurance is a combination of life insurance and investment. The aim of this research was to determine the potential benefits or losses of unit-linked life insurance products using a deterministic model and stochastic model. The calculation result using these model for a policy issued to a life aged 35, 45, and 55 and the benefit is paid till age 99 showed that the profit which insurer can claim only for insurance issued to a life age 25 years old.
