1.3 Measurement of Forecasting Error
Mean Absolute Percentage Error (MAPE) is a standard measure that
is often used in measuring the suitability of a forecasting or prediction
method. MAPE is used to see how far (in %) the prediction results
deviate from the actual data. The smaller the MAPE generated from a
forecasting method, the better the forecasting method will be
calculated by Equation (3) [14], where = Actual data, =
Forecasting data, = Number of data.

1.4 Descriptive Analysis
Descriptive analysis in this study was used to see an overview of the
central oxygen supply data at RSUD dr. Raden Soedjono Selong
January to November 2021.

Figure 1. Central Oxygen Supply.
Based on Figure. 1, it can be seen that the central oxygen supply of
RSUD dr. Raden Soedjono Selong in 2021, where the highest supply
of central oxygen is in March with a total of 23.5 tons and the lowest
