Abstract

This study aims to determine the level, attribute, and stimulus most considered by respondents in choosing expedition services. The method used is conjoint analysis by applying the conjoint analysis full-profile method to design the stimulus. The attributes and levels used are delivery type (ECO, REG, express, and same day), payment methods (cash and online transfers), service promotions (cost discounts and goods pick-up), and service responsiveness (responses to damage or loss of goods and responses to late delivery). The results of research conducted on 150 respondents showed that delivery type is the most preferred attribute with a value of 0,324. The levels with the largest part-worth of each attribute are REG (0.335), online transfers (0.210), cost discounts (0.270), and response to damage or loss of goods (0.250). The most popular stimulus is expedition services with standard shipping (REG), online transfers, cost discounts, and responses to damage or loss of goods.

Abstract

Parents want the best education for their children. Before starting the academic year, parents focus on finding the most suitable schools for their children. This study aimed to examine the factors affecting parents’ decision-making when selecting schools. A sample of 150 parents whose children are incoming high school students in 2020/2021 is involved in this study and selected using a snowball sampling technique and confirmatory factor analysis. This study has shown that the quality of the teachers is the factor that parents consider the most in their decision-making process. It is followed by the tuition and fee costs, the school facilities, and the school achievements.

Abstract

Students’ academic performances is an important factor as it affects students’ chances of higher education and job opportunities. While cognitive factor (e.g., intelligence quotient) plays a major role in students’ performances in academic environment, it does not guarantee students’ academic achievement. Instead, researches shows that non-cognitive factor can affects student performance as well. Three non-cognitive factor that will be researched in this study are motivation, self-related beliefs, and engagement. Using Structural Equation Modeling (SEM) as the method of choice to accommodate the study of the factors. 699 of students’ sample was taken from six public high school in Denpasar to conduct the research. SEM is used for its ability to analyze latent factors using measurement model and its ability to estimate multiple structural relation simultaneously. The model with a Goodness-of-fit (GFI) score of 0.981 confirms that Motivation does significantly directly affects student performances. Self-related beliefs and Engagement on the other hand significantly directly affects Motivation, hence the two constructs significantly indirectly affect student achievement.

Abstract

Program Education plays a vital role in improving human resources. But on the other hand, education costs are not cheap. For this reason, people need to prepare education funds from an early age. One way is to take part in an education insurance program. This is a business opportunity that a village-owned enterprise (BUMDes) can run by offering education insurance services to the public. This research aims to develop and use programming software to calculate education insurance premiums offered by BUMDes. The method used is The Equivalence Principle method. Based on the case study, the premium price calculated using software that has been developed is very competitive – below market price, depending on the interest rate and fees charged.

Abstract

The laundry business is one of the rapidly growing businesses in Indonesia. This development is due to factors such as the increasing busyness of the community, urbanization, and lifestyle changes. Deter_gent Laundry is one of the businesses that experienced a decrease in income and the number of customers from October to November in 2023 due to errors in recording the number of clothes, clothes fading, clothes shrinking, clothes lacking fragrance, and others. This study aims to analyze the problems that occur in the laundry process at Deter_gent Laundry and provide solutions to improve the quality of laundry services. This research uses the DMAIC method (Define, Measure, Analyze, Improve, Control). The results of this study indicate that the problems that occur are caused by several factors, namely human factors, method factors, material factors, and machine factors. To overcome these problems, it can be done by increasing the accuracy of employees, providing explanations, establishing and revising appropriate SOPs, and periodically controlling performance that deviates from SOPs. By implementing these solutions, it is hoped that the quality of laundry services at Deter_gent Laundry can improve and achieve the specified targets.

Abstract

Diphtheria is a disease that is easily transmitted, caused by a bacterium called Corynebacterium Diphtheria which attacks the respiratory tract so that sufferers experience difficulty breathing and can cause death. This research aims to model the factors method which is suspected of influencing diphtheria cases in East Java Province using spatial regression The data used is secondary data obtained from publications East Java Province Health Profile 2018 and publications from the Central Agency East Java Statistics (BPS). The results showed that the best model obtained was Spatial Error Model (SEM) with AIC=286,16 dan R2=55,98%. Variabels that significantly influence diphtheria in East Java province in 2018 are: population aged 10 years and over with junior high school education, the number of DPT-HB immunizations, and the percentage of poor people

Abstract

This study aims to model the Infant Mortality Rate (IMR) in East Nusa Tenggara Province using truncated spline nonparametric regression. In this study, IMR is associated with four predictor variables: the percentage of poor people, the percentage of pregnant women under 19 years of age, low birth weight, and life expectancy. These four variables have an unpatterned relationship, indicating the presence of a nonparametric component in the model. The truncated spline regression method was chosen because of its ability to handle nonlinear relationships between variables. The results showed that the best model was obtained using three knot points, which produced a coefficient of determination (R²) of 97.47%. This indicates that the truncated spline regression model is able to explain 97.47% of the variation in IMR in East Nusa Tenggara Province. In addition, the four predictor variables have a significant influence on the model, making a significant contribution in explaining the factors that influence IMR in the region.
