ABSTRACT
Salt production in Indonesia is generally carried out during the dry
season, where the amount of yield is influenced by rainfall in the
season. As for agricultural purposes, predictions of precipitation from
various national/international meteorological and climatological
agencies are expected to estimate the amount of sea salt
harvested. This study aims to ascertain the possibility of using rain
data to predict salt harvest and the urgency of rain monitoring in
specific locations, such as salt pans in Cirebon. Prediction of salt
production used multiple linear regression on data of sea salt
production, rainfall, and rainy days for eleven years in Cirebon. The
analysis results show that the precipitation and rainy days influence
salt harvest inversely. The number of rainy days is more influential
than rainfall on salt production. Data on rainfall and the number of
rainy days is only feasible to predict the fluctuations of salt yields in
Cirebon. However, they cannot accurately indicate the number of
