Abstract

PT XYZ is a company engaged in the rental of heavy equipment such as excavators, forklifts, bulldozers, and Wheel Loaders. The problem faced is unpreparedness in dealing with fluctuations in demand, so there is often a backlog or excess inventory. This research aims to improve the accuracy of demand forecasting and determine safety stocks to anticipate these uncertainties. The research was conducted using historical data on Wheel Loader rental requests from September to November 2024. The data was processed using the ARIMA (Autoregressive Integrated Moving Average) method through several stages, namely stationarity testing, identification of ACF and PACF, model estimation, parameter testing, white noise test, and selection of the best model. The resulting significant model was ARIMA (3,1,1), with a MAPE error value of 21% (79% accuracy), an increase of 9% compared to the previous method with an error of 30%. The results of the calculation of safety stock to deal with fluctuations in demand at various service levels show that the need for 2,688 units at the 90% level, increased to 3,444 units at the 95% level, and reached 3,900 units at the 97% level. This study shows that the ARIMA method is able to improve the accuracy of forecasting and provide a better basis for determining safety stock in managing fluctuations in heavy equipment rental demand.

Abstract

Urban aquaculture, like urban farming, entails using aquaculture technology to transform tiny, previously unutilized pieces of land in highly inhabited metropolitan areas into a useful area. Urban aquaculture, in broad terms, can be defined as the fish farming on small plots of land. Depending on the sort of consumable fish commodity to be grown, urban aquaculture can be implemented through home aquaculture and community aquaculture utilizing a variety of techniques. Creating a mandatory product involves the stages of development and design. At this stage, all product components, production costs, design, and assembly time are taken into account. Through sustainable product design and evaluation, it is possible to address the assembly performance and difficulties in the assembly process, as well as assembly time and costs. The design and development of this product use the Design for Manufacturing and Assembly (DFMA) method. DFMA is a method used to determine the product design with the best time and cost. In general, this method can also be used in development to improve the quality and measure the improvement of urban aquaculture product designs. It is hoped that urban aquaculture will provide an alternative product design to achieve high-quality products and low production costs.
