Abstract

Business on delivery sector has been growth recently, especially using railway. The development of infrastructures and facilities must be managed efficiently considering to an accurate information about the future need based on a historical data analysis. This article tried to develop models which can be used by decision makers to determine a reasonable plan to improve the profit. The Box-Jenkins method was employed to develop a model of historical data of goods distribution using train for Java and Sumatera area. The residuals was maintained using the GARCH model. This model was compared to the Trend and Seasonal Linear Model (TSLM) by evaluating the mean of absolute errors (MAE) and the root of mean squared errors (RMSE). The result shows that the ARIMA+GARCH model did better than ARIMA, SARIMA, and TSLM in predicting one and three month ahead for Java area, while the TSLM was more suitable for six and nine month forecasting than the others. On the other hand, the linear model provided the least values of MAE and RMSE for one, three, six, and nine month ahead prediction for Sumatera area

Abstract

The purpose of this study is to address the urgent needs at disaster evacuation sites, such as death, loss, injury, and displacement, by creating an emergency public kitchen. The methodology for designing this emergency kitchen involves an ergonomic approach that considers air circulation, necessary equipment, and supporting items like trash cans. The author follows the methods and design steps of Pahl and Beitz, which include four stages: planning and task explanation, product concept design, product shape design, and detail design. The results of this approach yield a new layout for an emergency kitchen that can support the logistical needs of disaster victims. This kitchen design can serve as a guide for universities and Muhammadiyah organizations to address the challenge of establishing public kitchens in disaster evacuation sites.
