Abstract

Food waste significantly contributes to global greenhouse gas emissions, water and air pollution, and socio-economic issues, including in Bali Province. In Bali, increased tourism correlates with population growth and a rise in organic waste, reaching up to 59.10% of total waste. This is largely dominated by imported fruits such as apples, oranges, pears, and grapes, which are also used for religious ceremonies. To mitigate imported fruit waste, limiting imports based on accurate demand forecasting is crucial. Traditional methods like Autoregressive Integrated Moving Average (ARIMA) exhibit limitations in modeling complex non-linear and seasonal patterns, particularly given the fluctuating apple consumption in Bali. Conversely, the Long Short-Term Memory (LSTM) algorithm, a deep learning approach, demonstrates superior capability in capturing linear, non-linear, and dynamic data patterns. This research compares the performance of ARIMA and LSTM models for predicting apple transaction data, evaluating them using the Root Mean Square Error (RMSE) and Mean Absolute Percentage Error (MAPE). The aim is to facilitate more precise apple import projections, thereby reducing waste. The results of the research confirmed that the ARIMA method was found to be superior in computational efficiency compared to LSTM, as it required no repeated training iterations. In contrast, LSTM required 25 iterations, making the computation time longer. However, LSTM showed higher accuracy with a MAPE value of 56.58% and RMSE of 28.93, though the difference in RMSE was insignificant compared to ARIMA (28.84), as both algorithms failed to capture the trend of sales spikes during holidays.
