Abstract
Penyediaan sumber daya energi dimasa mendatang menjadi masalah
tersendiri bagi negara-negara di dunia. Pemanfaatan energi arus laut merupakan
salah satu solusi untuk mengatasi masalah tersebut sehingga dapat menghemat
penggunaan energi fosil seperti minyak bumi dan gas. Selat Toyopakeh yang
terletak di Provinsi Bali merupakan salah satu perairan yang memiliki kecepatan
arus yang relatif besar sehingga sangat mendukung dalam pengembangan
pembangkit energi tenaga arus laut. Kecepatan arus laut pada daerah tersebut
dipengaruhi oleh terjadinya pasang surut atau biasa disebut dengan jenis arus
pasang surut. Besarnya kecepatan arus laut pada daerah tersebut bisa mencapai 2
m/s dalam kurun waktu 5 jam sampai 20 jam setiap harinya. Data pasang surut,
data batimetri, dan data kecepatan arus laut digunakan untuk pemodelan pola arus
yang menggunakan Software Delf3D. Dari hasil pemodelan diketahui kondisi arus
didominasi oleh arus pasang surut yang mempunyai tipe bolak-balik. Untuk
perhitungan potensi energi hanya dicari nilai daya yang dihasilkan dari gerakan
arus laut tersebut. Nilai rata-rata daya atau Average Power Density lokasi 1 yaitu
sebesar 252,9 kW/m2, sedangkan lokasi 2 sebesar 1,3 kW/m2.
Kata kunci : Pola Arus Laut, Energi Arus, Delf3D, Selat Toyopakeh, Bali

Provision of energy resources in the future becomes a problem for countries in
the world. Utilization of ocean currents energy is one solution to overcome the
problem so as to save the use of fossil energy such as petroleum and gas. The
Toyopakeh Strait located in Bali Province is one of the waters that has a
relatively large current velocity so it is very supportive in the development of
ocean current energy generation. The speed of sea currents in the area is
influenced by the occurrence of tidal or commonly called the type of tidal
currents. The velocity of sea currents in the area can reach 2 m / s in the period of
5 hours to 20 hours each day. Tidal data, bathymetry data, and ocean current
velocity data are used for modeling current patterns using Delf3D Software. From
the modeling result known that the current condition is dominated by the tidal
current having the type of back and forth. For the calculation of energy potential
only sought the value of power generated from the movement of the ocean
currents. The average power density of location 1 is 252.9 kW / m2, whereas
location 2 is 1.3 kW / m2
Key Word : Sea Flow pattern, Current Ocean Energy, Delf3D, Strait Toyopakeh
