Abstract
Kebutuhan listrik di Indonesia rata-rata tumbuh sebesar 7% per tahun. EBT dapat dimanfaatkan sebagai pembangkit listrik untuk menyokong pertumbuhan kebutuhan listrik, khususnya arus laut, karena kecepatan arus di Indonesia mencapai 0,5 m/s hingga 1,0 m/s. Energi arus laut ini dapat dimanfaatkan menggunakan turbin VAWT yaitu turbin Darrieus. Turbin Darrieus memiliki kemampuan dalam self-start yang kurang baik, sehingga digunakan flow disturbance yang bertindak sebagai pengganggu aliran. Pada penelitian ini, turbindiletakkan pada FA Well Tripod Platform PT PHE ONWJ dengan memanfaatkan kaki platform sebagai flow disturbance. Penelitian dilakukan dengan metode Computational Fluid Dynamics 2D menggunakan software Ansys Fluent 2022. Lokasi penempatan terbaik adalah pada section 2 titik B platform dengan kecepatan 0,64 m/s dan titik C platform dengan kecepatan 0,58 m/s. Variasi yang digunakan berupa jarak vertikal antara pusat turbin dengan pusat kaki platform yaitu y/D 0,0, 0,05, dan 0,1 pada kecepatan 0,64 m/s dan 0,58 m/s. Dari hasil simulasi 2D didapatkan hasil bahwa peletakkan turbin dengan jarak y/D 0,0 pada kecepatan 0,64 m/s memberikan peningkatan torsi paling besar yaitu 13% dibanding turbin Darrieus konvensional. Didapatkan daya sebesar 80,81 Watt serta energi sebesar 707,9 kWh yang dapat digunakan sebagai sumber energi alternatif pada FA Well Tripod Platform PT PHE ONWJ.

The average electricity demand in Indonesia grows by 7% per year. NRE can be used as a power plant to support the growth of electricity demand, especially ocean currents because the current speed in Indonesia reaches 0.5 m/s to 1.0 m/s. This ocean current energy can be utilized using a VAWT turbine, the Darrieus turbine. The Darrieus turbine has poor self-start capability, so a flow disturbance is used, which acts as a flow disturbance. In this study, the turbine is placed on the FA Well Tripod Platform PT PHE ONWJ by utilizing the platform foot as a flow disturbance. The research was conducted using the Computational Fluid Dynamics 2D method using the Ansys Fluent 2022 software. The best placement location is at section 2, point B platform with a speed of 0.64 m/s and point C platform with a speed of 0.58 m/s. The variation used is the vertical distance between the center of the turbine and the center of the platform foot, y/D 0.0, 0.05, and 0.1 at speeds of 0.64 m/s and 0.58 m/s. From the 2D simulation results, it is found that laying the turbine with a distance of y/D 0.0 at a speed of 0.64 m/s gives a tremendous torque increase, which is 13% compared to a conventional Darrieus turbine. The torque is then converted and obtained power of 80.81 Watt and energy of 707.9 kWh, which can be used as an alternative energy source on FA Well Tripod Platform PT PHE ONWJ.
