METHODS

This study examines the salt harvest in the Cirebon district.
From the approximately 69,8 km long coastline of Cirebon District,
more than 80% of the shoreline is salt pans. Salt pans in Cirebon
obtain raw materials from seawater in the Java Sea. The Cirebon
coast, on the north coast of Java, is vulnerable to climate change,
as represented by rainfall, temperature, and wind speed changes
(Mulyasari et al., 2019).

Data on sea salt yield (Y, tons) was collected from the
Ministry of Marine Affairs and Fisheries (KKP). In contrast, climate
data, in this case, it is rain (X, mm) has been downloaded from
Copernicus Climate Data storage and Meteorology (Anonim,
2023a), Climatology, and Geophysical Agency (BMKG) through
the site of BMKG (Anonim, 2023b). Rainfall data is processed by
filtering precipitation data during the salt production period (May-
November) to obtain monthly rainfall accumulation (X , mm) data
1
and rainy days (X , day) during the dry season. Researchers have
2
collected data on salt harvest, rainfall and the number of rainy days
in Cirebon for eleven years (2011-2021).
