Abstract
Dampak negatif penggunaan bahan bakar fosil mendorong minat yang cukup besar dalam eksplorasi dan penelitian energi terbarukan, salah satunya adalah energi gelombang laut yang memiliki prospek menjanjikan di masa depan. Karenanya, perlu dilakukan investigasi di titik-titik potensial yang tersebar di wilayah Indonesia melalui studi yang lebih komprehensif dimulai dari karakteristik gelombang yang ada hingga pertimbangan dalam implementasi wave energy converter (WEC) disana. Pada penelitian ini difokuskan pada eksplorasi potensi energi gelombang laut di perairan barat Provinsi Lampung yang dilakukan berbasis pemodelan numerik. Software Delft3D-WAVE yang menggunakan input dari data gelombang laut ECMWF–Era 5 selama 12 tahun (2008 – 2019) diaplikasikan untuk mendapatkan tinggi gelombang signifikan, periode energi, dan arah gelombang yang berguna untuk perhitungan potensi energi gelombang laut di lima titik lokasi uji. Luaran pemodelan ini juga divalidasi menggunakan data dari satelit altimetri AVISO. Hasilnya, daya terbesar yang dapat dicapai sebesar 18.97 kW/m pada periode bulanan, 18.45 kW/m pada periode musiman, dan 15.15 kW/m pada periode tahunan. Selain itu, perairan barat Provinsi Lampung memiliki nilai statistik pendukung gelombang laut yang cukup bervariasi dengan nilai CoV berkisar 0.5–0.9, MVI berkisar 1.7–3.9, SVI berkisar 2.3–5.5, AVI antara 3.5–8, OHI berkisar 0–6.7, dan WEDI berkisar 0–0.2. Berdasarkan kriteria implementasi WEC, Stasiun 1 yang berada di Kecamatan Wai Batang merupakan lokasi terbaik sehingga disarankan untuk dikembangkan dan diimplemantasikan WEC. Dari beberapa WEC yang diterapkan seperti Pelamis, Langlee, Wave Dragon, dan Aqua Buoy. availability terbesar dicapai oleh Langlee dan Wave Dragon sebesar 100%, sedangkan untuk capacity factor terbesar dicapai oleh Wave Dragon pada skala 0.2 sebesar 46.91%.

The negative impact of fossil fuels has prompted considerable interest in the exploration and research of renewable energy, one of which is wave energy which has promising prospects in the future. Hence, it is necessary to investigate potential points spread across the territory of Indonesia through a more comprehensive study, starting from the characteristics of the existing waves to considerations in implementing the wave energy converter (WEC) there. This research focuses on exploring the wave energy potential in the western oceans of Lampung Province, which is carried out based on numerical modeling. The Delft3D-WAVE software, which uses input from ECMWF–Era 5 wave data for 12 years (2008 – 2019), was applied to obtain significant wave heights, energy periods, and wave directions for calculating the wave energy potential at five test location points. The modeling outputs were also validated using data from the AVISO altimetry satellite. As a result, the maximum power that can be achieved is 18.97 kW/m in the monthly period, 18.45 kW/m in the seasonal period, and 15.15 kW/m in the annual period. In addition, the western oceans of Lampung Province have waves supporting statistical values, which are pretty varied with CoV values ranging from 0.5 to 0.9, VMI from 1.7 to 3.9, SVI from 2.3 to 5.5, AVI from 3.5 to 8, OHI from 0 to 6.7, and WEDI ranged from 0–0.2. Based on the criteria for implementing WEC, Station 1 in Wai Batang District is the best location, so it is recommended to develop and implement WEC. Of the several WECs implemented, such as Pelamis, Langlee, Wave Dragon, and Aqua Buoy. Langlee and Wave Dragon has the highest availability of about 100%, while Wave Dragon achieved the most significant capacity factor at Downscale 0.2 of 46.91%.
