Abstract

This study purposed to know the effect of art and socio-culture on the public perception of tattoos. The data used in this study is the primary data collected using a questionnaires distributed to 200 people with 100 non-tattooed people and 100 tattooed people. This study used covariance-based Structural Equation Modeling (SEM) with AMOS software, and used three latent variables such as art, socio-culture and tattoo perception. The results of this study show art and socio-culture have a significant effect on tattoo perception.

Abstract

Current technological advances cause information to be obtained quickly. Such information can be obtained through printed media or electronic media. Television is included in the category of electronic media. The infotainment program is one of the television programs. Almost all television stations have infotainment programs running every day. This proves that people love the infotainment program, so the infotainment program still running until now. People’s as watchers/audiens of the infotainment program have the right to provide an assessment of the quality of infotainment programs related to satisfaction and preference to assist in the development of infotainment programs. To understand people's preferences for infotainment programs, it can be done using conjoint analysis. In this research, it was found that the attributes that influence the people’s in watching infotainment program are presenter, air time, and program duration. In general, the infotainment program that desired by the people was an infotainment program that has a paired presenter, running at night with a half hour run time

Abstract

Pension plan is an effort to anticipate the life of old on the day. In the pension program, there are two methods of normal due’s calculation to be paid by the insured each year, the Entry Age Normal method, namely calculation of normal dues with constant premiums and projected unit credit method, namely calculation of normal dues with Premium Increases Each year or is not constant. This paper wants to develop an inconstant premium calculation method with constant premium increase annually. Where the pension plan participants’ age when he joined the pension plan is 19 years and the retirement age on this contract is 55 years, with premium increases of 5% of the normal dues early. The large ratio of premiums is, for dues normal at the age of 19 years until the age of 28 years, but for dues normal at the age of 29 years to the age of 33 years and to normal dues at the age of 34 years old until the age of one year before retirement.

Abstract

Contract options are the most important part of an investment strategy. An option is a contract that entitles the owner or holder to sell an asset on a designated maturity date. A binary or asset-or-nothing option is an option in which the option holder will perform or not the option. There are many methods used in determining the option contract value, one of this is the Monte Carlo Quasi method of the Faure random. The purpose of this study is to determine the value of binary type option contract using the Quasi Monte Carlo method of the Faure random and compare with the Monte Carlo method. The results of this study indicate that the option contract calculated by the Monte Carlo Quasi method results in a more fair value. Monte Carlo method simulation 10.000 generate standard error is 0.9316 and the option convergence at 18.9144. While Quasi Monte Carlo simulation 3000 generate standard error is 0.09091 and the option convergence at 18.8203. This show the Quasi Monte Carlo method reaches a faster convergent of Monte Carlo method.

Abstract

At this time, almost everyone once to consume instant noodles. The high interest of public on the instant noodles should be balanced with enough knowledge about the noodles and its nutritional content, either on it’s instant noodles which have similar nutrient content and nutrient content that become identifier of each this group of noodles. The method can be used to obtain information on several brands of instant noodles that have similar nutrient content and nutrient content type that become identifier of each group of instant noodles is biplot analysis. Biplot analysis can show mie and nutrient content types simultaneously in a two-dimension plot. So that from a plot shows noodles and nutritional content types simultaneously, so that obtain information about the instant noodle that have similar nutrient content and nutrient content types into identifier of each group of instant noodles. This study was used 33 brands of instant noodles as observed objects with the type of nutrient content were observed there were nine. This study aims to find out some instant noodles that have similar nutrient content and nutrient content type that become identifier of each group of instant noodles. From the biplot analysis, obtained six groups of instant noodles with different identifier variables.

Abstract

This study calculates non renewable monthly premiums and renewable monthly premiums for health insurance. Formulations used in this study were derived from the equations used by Wilandari (2007). The monthly premium calculation  uses a CSO mortality table and an interest rate of 6%. To illustrate the calculating of the premium it is assumed that a family consist of a father, a mother and a son, respectively with age 40, 36 and 9 years old. The results obtained were that the  total premium is paid amounted to Rp. 155.02,00 every month for 20 years. Benefit for the cost of room, doctor visits, and the cost of care respectively were Rp. 200.000,00 per day, Rp. 75.000,00 per day and Rp. 4.000.000,00 per periode. Average duration of treatment was 180 days. The renewable  monthly premium was paid in different amounts each year, with the range from Rp. 80.425,00 to Rp. 406.465,00. From this study, Although initially the renewable premium is cheaper than the non renewable premium, at the end it is more expensive than the non renewable premium. In this study it was obtained too that 12 times the monthly premium  is greater than 1 times the annual premium.

Abstract

Ordinary Least Squares (OLS) used to estimate the parameters in the regression analysis. If one of the assumptions is not fulfilled, the results of the OLS are no longer best, linear, and unbiased properties. The aim of this research was to find out the application of Newey West method to correct standard error when heteroscedasticity and autocorrelation occurred, and to compare the results of OLS with Newey West method on secondary and simulation data. OLS can still be used to estimate the regression parameter when heteroscedasticity and autocorrelation occurred. However, it will cause bias on standard error of parameter. A method which can correct the standard error of parameters to be unbiased parameter is Newey West method. The secondary data about Passenger Car Milage and data simulated contain heteroscedasticity and autocorrelation. The analysis showed that the Newey West method were known is able to correct standard error when heteroscedasticity and autocorrelation occurred on both of data. It was obtained that Newey west method with and changes the value of the bias standard error of OLS to be unbiased.

Abstract

Sensitivity analysis can be used to carry out hedging strategies. The sensitivity value measures how much the price change of the option influenced by some parameters. The aim of this study is to determine the sensitivity analysis of the buying price of European option by using the Greek method on Black Scholes Formula. From this study we get the values of delta, gamma, theta, vega, and rho. The values of deltas, gamma, vega, and rho are positive, which means that the value of the option is more sensitive than the corresponding parameter. The most sensitive value of gamma is obtained when the stock price approaches the strike price and approaches the expiry date. The value of theta obtained is negative and hence the most sensitive theta value is when the value is getting smaller. While, the most sensitive value of vega is obtained when the stock price is close to the strike price and is far from the expiry date. The most sensitive value of rho is obtained when the stock price gets bigger and farther from the expiry date.
