ABSTRAK
Husein Alfarizi. 26050118140080. Pengaruh Surface Heat Flux terhadap
Variabilitas Suhu Permukaan Laut dan Klorofil-a di Laut Selatan Jawa (Anindya
Wirasatriya dan Kunarso)
Indonesia sebagai wilayah yang terletak di daerah tropis mendapatkan distribusi
panas yang lebih besar daripada belahan bumi lainnya dan memiliki peran penting
dalam fenomena interaksi atmosfer dan laut di wilayah Indo -Pasifik. Pertukaran
panas antara laut dan atmosfer memengaruhi proses dinamika keduanya. Penelitian
ini bertujuan untuk menginvestigasi pengaruh variabilitas Surface Heat Flux
terhadap variabilitas suhu permukaan laut dan klorofil-a pada daerah upwelling di
laut Selatan Jawa. Penelitian dilakukan dengan pendekatan secara deskriptif
kuantitafif melalui pengolahan data spasial dan temporal klimatologi bulanan
selama 10 tahun dari 2007 – 2016 di daerah upwelling Laut Selatan Jawa. Data yang
digunakan adalah Shortwave Radiation, Longwave Radiation, Latent Heat Flux,
Sensible Heat Flux, Suhu Permukaan Laut, Klorofil-a, Angin Permukaan, dan
Mixed Layer Depth. Hasil menunjukkan bahwa Laut Selatan Jawa menerima panas
rata-rata sebesar 547.8 W/m2 pertahun. Fluktusasi Net Heat Flux didominansi oleh
penerimaan panas oleh Shortwave Radiation dan pelepasan panas oleh Latent Heat
Flux. Net Heat Flux memiliki hubungan yang sangat kuat dengan suhu permukaan
laut dengan korelasi terbaik sebesar 0.84 dan 0.83 pada lag+2 dan lag+3 bulan
menunjukkan bahwa Net Heat Flux berperan penting dalam memodulasi perubahan
suhu permukaan laut 2-3 bulan kedepan. Peningkatan klorofil-a secara signifikan
terjadi setelah Net Heat Flux mengarah positif atau terjadi pemanasan laut yang
menyebabkan pendangkalan Mixed Layer Depth sehingga memicu produktivitas
primer pada musim timur bersamaan dengan pengangkatan nutrisi oleh EMT dan
EPV.
Kata kunci : Surface Heat Flux, Suhu Permukaan Laut, Klorofil-a, Upwelling,

ABSTRACT
Husein Alfarizi. 26050118140080. The Effect of Surface Heat Flux on Variability
of Sea Surface Temperature and Chlorophyll-a in the South Java Sea (Anindya
Wirasatriya dan Kunarso)
Indonesia as a region located in the tropics gets a greater heat distribution than the
other hemisphere and has an important role in the phenomenon of atmospheric and
ocean interactions in the Indo-Pacific region. The heat exchange between the ocean
and the atmosphere affects the dynamics of both. This study aims to investigate the
effect of heat flux variability on sea surface temperature variability and chlorophylla in upsurface welling areas in the South Java sea. The study was conducted with a
quantitative descriptive approach through climatological spatial and temporal data
processing for 10 years from 2007 – 2016. The data used are Shortwave Radiation,
Longwave Radiation, Latent Heat Flux, Sensible Heat Flux, Sea Surface
Temperature, Chlorophyll-a, Surface Wind, and Mixed Layer Depth. The results
show that the South Java Sea receives an average heat of 547.8 W/m2 per year. Net
Heat Flux fluctuations are dominated by heat intake by Shortwave Radiation and
heat release by Latent Heat Flux. Net Heat Flux has a very strong relationship with
sea surface temperature with the best correlation of 0.84 and 0.83 at lag+2 and lag+3
months indicating that Net Heat Flux plays an important role in modulating changes
in sea surface temperature in the next 2-3 months. A significant increase in
chlorophyll-a occurred after the Net Heat Flux was positive or there was ocean
heating which caused the shoaling of Mixed Layer Depth, resulting in primary
productivity in the east monsoon along with nutrient rich entraintment to the surface
by EMT and EPV.
