1 INTRODUCTION
Prediction is a process to estimate the possibility that will occur in the
future based on information or data in the past and currently owned,
so that errors formed can be minimized [1]. There are several methods
of forecasting between Random Forest and Decomposition. The
Random Forest method is a set of decision trees that are used for
classification and prediction of data by entering inputs into the root part
that is above and then down to the part of the leaf that is below [2].
Decomposition is a method that uses four main components in
forecasting future values. The four components include trend,
seasonality, cycles, and errors [3].
This forecasting method can be applied in various fields, one of which
is the health sector to determine the amount of oxygen supply in the
central hospital in the future. Hospitals are health service institutions
that provide complete individual health services that provide inpatient,
outpatient, and emergency services. In April 2021, Indonesia was
recorded to have 3,039 hospitals. This addition occurred not only due
to the need for health services in general, but also because Indonesia,
which is currently still hit by the Covid-19 pandemic, which requires an
increase in the number of hospitals or health service institutions [4].
The spike in Covid-19 cases has resulted in many impacts, one of
which is the scarcity of medical gas in the form of oxygen [5]. In the
middle of 2021, oxygen scarcity occurred in Java and Bali due to the
Covid-19 pandemic [4]. This scarcity has an impact on the supply of
oxygen to other hospitals in Indonesia. One of them is RSUD dr. R.
Soedjono Selong in NTB Province. RSUD dr. R. Soedjono Selong
usually gets a supply of 100 tubes per day, but due to the impact of
oxygen scarcity on the islands of Java and Bali, dr. R. Soedjono
Selong gets an oxygen supply of 60 to 80 tubes per day. This is also
caused by the diversion of oxygen which was originally to be supplied
