Abstract

As a major tourist destination, Bali has become an icon for tourism in Indonesia. In general, the number of foreign tourist visits shows an increasing trend. However, there is considerable fluctuation in the number of visits which is affected by season. In another word, there is a stochastic trend in the number of tourist visits. Policy makers need a method to predict this tourist visits. A commonly used method to predict tourist visits is time series analysis. Time series analysis has been used in various fields such as finance, business, engineering, meteorology, geophysics, and tourism, to name but a few. Research on forecasting tourist visits usually uses univariate data. This research aims to forecast the number of foreign tourist visits from four major countries such as Asia Pacific, ASEAN, America, and Europe simultaneously using Bayesian vector autoregression with normal-inverse-Wishart prior. First data is plotted to see its characteristics. Then the data is modeled using Bayesian vector autoregression. In this stage normal-inverse-Wishart prior is used. Next, Markov chain Monte Carlo is conducted to make a prediction from the posterior distribution. The forecast suggests that the number of tourist visits in general increased, albeit some fluctuation in some months.

Abstract

A queue is a waiting line from a service facility. Long queues are caused by the number of consumers who come more than the number of service facilities, it is necessary to apply a queuing model to overcome long queues. This research was conducted at Mc Donald's Jimbaran fast food restaurant because the fast food restaurant is located in a tourist and lecture area, causing queues. The current condition at Mcdonald’s Jimbaran there are more than one service facility, the discipline of the first come first service (FCFS) queue is in accordance with the single-phase multi-channel. After analyzed with data from 31 May 2022 to 06 June 2022 for 7 days. Based on the results of the analysis obtained, it can be concluded that at lunch time requires 4 services while at dinner time only requires 2 service.

Abstract

Business actors require banking services that effectively support their financial activities. The variety of available banks requires institutions to understand customer preferences in order to develop competitive strategies. This study aims to determine the optimal strategy that banks may implement based on the preferences of micro, small, and medium business actors using game theory. The research employed a two-stage data collection process. The first stage involved 30 respondents to identify the two most preferred banks, namely Bank A and Bank B. The second stage involved 108 respondents, determined through the Yamane formula, to evaluate eight strategic banking attributes. Payoff values were calculated using the difference in preference probabilities for each attribute. Game theory analysis used a two-person zero-sum game with pure strategies. The results indicate that Bank A optimal strategy is ATM availability, while Bank B optimal strategy is loan interest rates. These findings may assist banks in enhancing their services according to business actors’ preferences.

Abstract

Agricultural insurance is insurance that exists in the agricultural sector. Agricultural insurance is relatively recently introduced in Indonesia, there are three types of agricultural insurance, agricultural insurance based on losses, price-based agricultural insurance, and index-based agricultural insurance. In this study, the type of agricultural insurance used is index-based insurance, especially based on the rainfall index. The purpose of this study was to determine the procedures required to determine the price of agricultural insurance premiums based on the rainfall index and calculate agricultural insurance premiums using the Weibull distribution or mixed exponential distribution. Furthermore, where the premium price is relatively smaller and close to the insurance premium recommended by the government. In this study, the premium price generated is different for the two distributions, with a not too large difference in the range of rainfall resulting from the simulation of rainfall obtained by using a mixed exponential distribution to get a smaller premium value.

Abstract

Transportation problems experienced by UD. Raja Wangi in distributing Maha Dewa fragrant incense. UD. Raja Wangi incurs high transportation costs due to irregular direct distribution patterns and has not paid attention to the route to be passed. One way to solve the problem is to use transportation methods to get the optimal distribution route so that the transportation costs incurred are minimal. This study aims to solve transportation problems using the Bilqis Chastine Erma (BCE) method and the Sumathi Sathiya method with the Stepping Stone method to obtain the optimal solution. The Bilqis Chastine Erma (BCE) and the Sumathi Sathiya methods are indirect methods of solving transportation problems by obtaining an initial solution. After obtaining the initial solution, the Stepping Stone method is used to obtain the optimal solution. The results showed that the optimal solution using the Stepping Stone method based on the initial solution of the Bilqis Chastine Erma (BCE) method obtained a total transportation cost of Rp42,937.00 while the optimal solution using the Stepping Stone method based on the initial solution of the Sumathi Sathiya method obtained a total transportation cost of Rp38,727.00. In addition, the Sumathi Sathiya method gets a difference in total transportation costs of Rp11,790.00 or 23% of the total transportation costs incurred by the UD. Raja Wangi. Therefore, the Sumathi Sathiya method is the best solution for minimizing transportation costs.
