Abstract

This study to determine the selection of computer hardware using fuzzy database method. This is because of many series of hardware produced by the manufacture, so the public will be confused in determining the choice of a combination of computer assembly. In this study the processor, motherboard, random access memory, hard disk, vga cards, power supply studied to find best recommendation. The result obtained from this study these several results obtained in study in the form of recommendation, that is if the recommendation value 0 then the hardware is not displayed as a decision, whereas if the recommendation value is greater than 0 and less than or equal to 1 the device will be displayed as a decision according to the value of its recommendation.

Abstract

This study examines about last survivor life insurance with return of premium for married couples with independent and dependent mortality model. By using Frank copula, Clayton copula, Gumbel copula and Indonesian Mortalita Table 2011, the impact of future life dependence on single premiums and annually premium is evaluated. Based on the calculation of premium with a 10 year contract for the insured parties aged 58 years and 55 years with interest rate used 6.5%, the value of insurance premium last survivor with return of premium is more expensive than without return of premium. The greater the dependency, the more expensive the price of the premium.

Abstract

Last Survivor Insurance is life insurance for two or more participants with premiums paid until the death of the last participant. This study discusses last survivor endowment insurance for two participants in a married couple. Compensation is paid after the second person dies or both stills alive after the end of a contract. The purpose of this study is to determine the value of non-constant annual premium and benefits reserves in the last survivor endowment insurance. The equivalence principle is used for calculation of premiums. Furthermore, the benefit reserve formula is determined using a prospective method. The value of the benefit reserve will continue to increase as long as premium payments are still being made.

Abstract

The characteristics of a function are usually investigated by looking at the continuity of the function. But what happens if a function does not have continuous properties? To what extent can the characteristics of continuous function be maintained for discontinuous cases? The stochastic function that is widely involved in solving problems in the field of average financial mathematics is a discontinuous function. This is reflected by the acquisition of a smooth curve from the modeling drawing obtained. Today, the nature of continuous functions in [a, b] has been widely studied and developed. Some properties of the continuous function can be extended to the appropriate discontinuous function. In this paper, there will be some integral reviews for discontinuous functions which are closely related to stochastic functions.

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

The proportion of a portfolio can not eliminate risk as a whole but can reduce risk compared to investing in one type of security. One way to determine the optimal portfolio is to use the rank utility function. The purpose of this study is to determine the optimal portfolio of shares of PT. Adhi Karya (Persero) Tbk. (ADHI) and PT. XL Axiata Tbk. (EXCL) for the period January 2017-December 2018 by determining expected returns, variances, standard deviations, covariates, correlation coefficients between shares, and formulating the portfolio equation into a utility function with a rank of 0.5. This study produces a utility value (U (?)) of 0.996181 which means that the level of satisfaction with the proportion of shares of the portfolio is 99.618183%. This value is very high so the proportion of each share is well performed.

Abstract

The problem of transportation is a problem of distributing goods from several sources to several destinations with the aim of minimizing shipping costs. Distribution activities in a company sometimes experience problems in transportation problems so that a model is needed to determine the optimal distribution using the transportation model. This study aims to determine the route of distribution of beras putri sejati 25 kg in UD Sinar Jaya Abadi so that optimal expenses can be obtained using improved exponential approach and zero suffix method. Based on the calculation results, both methods produce the same three distribution path. The first distribution channel is from Agen Monang Maning to Toko Mekar Sari and Subur Jaya. The second distribution line from the Agen Gatsu Barat to UD Mas Ayana and Toko Dharma. The third line from agen Gianyar to UD Sinar Wangi, Toko Sari Artha, UD Amertha, and Toko Ayu Mega with optimal distribution costs of Rp 1.575.815.00. The difference or efficiency of the total costs incurred in the distribution before and after optimization by UD Sinar Jaya Abadi Rp 499,190.00 or 24%.

Abstract

Forecasting is science to estimate occurrence of the future. This matter can be conducted by entangling intake of past data and place to the next period with a mathematical form. This research aims to estimate the number of foreign tourists visiting Bali models using autoregressive moving average exogenous (ARMAX). The data used in this study is the number of tourists in Australia and the number of tourists in the RRC as a variable Y, and foreign currency exchange rate AUD, Chinese Yuan, and Export Import as the X factor from the period July 2009 to July 2014. In the analysis can be obtained in the best ARMAX models of the number of tourists in Australia is ARMAX(1,2,2) and the best model of the number of tourists in the RRC does not exist because the data for the ARMAX model parameters tourists no significant RRC.

Abstract

Satisfaction level on inpatient service is determined by several factors such as the perceived quality about nursing and/or medical services. This study is directed to determine those factors that affect the satisfaction level of the patient families regarding the quality of inpatient service in one public hospital at Denpasar City of Bali. The data from 150 families who utilised inpatient services were collected by using a self-administered questionnaire and were analysed by applying factor analysis to extract the influential factors. In addition, the causal relationship among factors were studied by utilising partial least squares structural equation modeling (PLS-SEM). Factor analysis confirmed there are five influential factors in determining quality of services, i.e. attention, tangible aspects, assurance, reliability, and responsiveness. By positioning these factors as the exogenous and quality of inpatient services as the endogenous one, we found all factors had determination power as much as 36.6 percent. Furthermore, the satisfaction level regarding the quality of inpatient service had been significantly affected as much as 0.917 with the coefficient of determination’s value is 84.0 percent.

Abstract

The volatilities of time series data often experience heteroscedastic problems. Heteroscedasticity is a nuisance variable in the regression equation having a variance that is not constant. Therefore, methods to analyze the problem of heteroscedasticity are needed. This study aims to demonstrate how to eliminate the problem of heteroscedasticity. The method used is, GoldFeld-Quandt. As for eliminating the problem of heteroscedasticity by assuming the variance of interference variables proportional to E(Yi)2
