Abstract

The use of eco-friendly shopping bags needs to be encouraged to reduce the use of plastic bags. According to the results of observations and interviews, it is known that the interest of students in using environmentally friendly shopping bags is still low. The aim of this study is to analyze the factors that influence the intention of students in using environmentally friendly shopping bags in the Special Region of Yogyakarta. This study uses multiple linear regression method. Purposive sampling is applied, with a sample of students from 5 universities as many as 100 respondents. Variables in this study using the development of Theory of Planned Behavior by adding variables of environmental awareness and support for the Prohibition of plastic bags. The results showed the correlation coefficient of 0.781 and the coefficient of determination of 0.609, which means there is a strong linear relationship between the dependent variable and all independent variables. Attitude variables, behavioral control and support for the Prohibition of plastic bags bags proved to have a significant effect on the intention to use environmentally friendly shopping bags for each value of regression coefficients were 0.221, 0.400 and 0.158, while the subjective norms and environmental awareness variables had no significant effect. For this reason, recommendations are given to variables that are proven to have a significant effect. Attitude variables are encouraged by promoting the use of environmentally friendly shopping bags to the public through various media, while for behavioral control variables, socialization needs to be carried out to the public regarding the importance of using environmentally friendly shopping bags and the adverse effects of using plastic bags. For recommendations related to variable support for the Prohibition of plastic bags can be done by encouraging plastic bag manufacturers to produce plastic bags from environmentally friendly materials (bioplastics).

Abstract

Research on artificial intelligence to determine water quality has been widely developed as a human endeavor toimprove the quality of life. This study employs an artificial neural network (ANN) to determine the optimalclassification model for determining the safety of water. This study uses existing Kaggle generic datasets. Numerouspreprocesses were performed on the dataset starting from cleaning the data from missing values and outliers toequalizing the weights of each parameter with the min-max scaler. This study compares the accuracy of ANN modelin various scenarios constructed with 10, 15, 20, and 30 neurons. Scaled Conjugate Gradient is implemented as thelearning algorithm for developing the prediction model. The obtained results of the experiments vary betweenscenarios. Overall accuracy increases when the number of neurons is between 10 and 20, and decreases when thenumber of neurons is between 20 and 30.

Abstract

UD. Pandawa Tire is a UD engaged in the manufacture of tires retreaded. The production process at Pandawa Tires still often does overtime due to the number of new employees 9 people and the average target of making 60 tires every day which causes fatigue and mental and physical workload. The analytical methods used to measure the physical and mental workload of workers are Cardiovascular Load (CVL) and the National Aeronautics and Space Administration Task Load Index (NASA-TLX). The results showed that the greatest physical workload was felt by workers with a CVL percentage of 46.1%, which was between 30% to 60% in the medium category, meaning that improvements are needed but not urgent. While the results of the measurement of mental workload showed that all workers were included in the high category, with the largest NASA-TLX score of 83.33. Correlation Test was Pearson Product Moment conducted to see the relationship between the value of the physical and mental workload received by the worker. The results of the calculation of the correlation test show that there is a relationship between CVL and NASA-TLX, although there is a correlation, but the correlation is significant in influencing each other between the amount of physical workload and mental workload felt by workers. The correlation value of r obtained is 0.672. Which means that there is a strong positive correlation between the physical workload and the mental burden felt by the Pandawa tire workers
