Abstract

Subjective fatigue measurement instruments, based questionnaire, is a measure that is widely used for reasons of practicality and measurement results can be obtained quickly. For the purposes of measuring fatigue, there are a number of questionnaires commonly used abroad, but not a lot of literature with a case study in Indonesia that utilize this instrument. Of course, the reason for the use of the instrument is based on the expectation that the instrument has high validity and reliability, and if possible to have a high level of practicality as well. Asssment Fatigue Scale (FAS) is one of the suggested use as a measurement of worker fatigue. The instrument consists of a 10 item questionnaire with good reliability level. The discussion in this paper covers Measurement Scale Fatigue testing results via questionnaires measuring fatigue, adapted from the FAS in English and translated into Indonesian. DSS consists of 10 questions using 5 Likert scale, for the answer options are: never (1), sometimes (2), perceived a regular basis (3), is common (4), is always experienced (5). Relaibilitas test results using Cronbach alpha values obtained value of 0812, and can be improved if the item is question number 3 is removed. By implication, this questionnaire is good enough to use as a measuring instrument fatigue, but the level of proficiency in Indonesian language, in this CMS, needs to be repaired, especially for question number 5 and 3 if the level of validity and reliability to be improved, although the increase may not be too significant.

Abstract

Educational games are the ideal medium to see the extent to which a student's performance will be assessed. However, to integrate educational games has the technical and practical challenges of their own. This study will be directed to the development of a game that can be used to measure the kind of intelligence and capabilities of a child based on the reference of Psychology Howard Gardner's theory kuisinoerThe purpose of writing is the development of gaming applications with HTML5 and JavaScript enabled to measure intelligence. The data taken from the distribution of questionnaires to 30 respondents were randomly. The data were analyzed by finding the average difference between the results of tests using questionnaires to play the game. From these results it can be concluded that there is a gap/difference between the average differences among the results of the two tests.

Abstract

Determining a good route is a major problem in a transport process in the company. This case study aims to overcome the problem of determining the route or often called the Traveling Salesman Problem (TSP) is optimal. This problem will be solved by the optimization method in determining the route, which is more systematic in PT Anugerah Mandiri Success. Metaheuristic methods, such as Hybrid Firefly Algorithm is used to assist the system in the process of determining the route. Hybrid Firefly Algorithm combines heuristic method of Nearest Neighbor Heuristic with metaheuristic method of Levy Flight Discrete Firefly Algorithm. The indicators used in this case study are the total distance traveled and total fuel used. Methods Object Oriented Analysis andDesign (OOAD) is used to develop an information system, which consists of determining system requirements, system architecture design, and design to the trials of the system were developed. The results of the constructedsystem provide a solution in the form of route determination with a total distance of 165.1 kilometers with a fuel consumption of 11,793 liters. These results are much better when compared with historical data that has a totaldistance of 260.8 kilometers with a fuel consumption of 18,628 liters.

Abstract

Multicollinearity and outliers are the common problems when estimating regression model.   Multicollinearitiy occurs when there are high correlations among predictor variables, leading to difficulties in separating the effects of each independent variable on the response variable. While, if outliers are present in the data to be analyzed, then the assumption of normality in the regression will be violated and the results of the analysis may be incorrect or misleading. Both of these cases occurred in the data on room occupancy rate of hotels in Kendari. The purpose of this study is to find a model for the data that is free of multicollinearity and outliers and to determine the factors that affect the level of room occupancy hotels in Kendari. The method used is Continuous Wavelet Transformation and Partial Least Squares. The result of this research is a regression model that is free of multicollinearity and a  pattern of data that resolved the present of outliers.
