Abstract

Asosiasi Energi Laut Indonesia (ASELI) pada tahun 2014 telah memberikan hasil ratifikasi potensi energi arus laut di Indonesia sebesar 17.989 MW. Jumlah tersebut terbilang cukup besar untuk hasil beberapa titik potensi di wilayah Indonesia. Namun, potensi arus laut di Indonesia belum dimanfaatkan secara optimum, padahal teknologi pembangkit listrik tenaga arus laut (PLTAL) sedang berkembang pesat di dunia. Teknologi PLTAL yang sudah tersedia di dunia tidak bisa langsung diterapkan di Indonesia, karena kondisi perairan di Indonesia tergolong berkecepatan arus rendah, tidak seperti pada beberapa negara di dunia yang tergolong berkecepatan arus tinggi. Sehingga, dibutuhkan teknologi turbin PLTAL yang dapat bekerja pada kondisi wilayah perairan di Indonesia, secara umum berkecepatan arus rendah. Teknologi turbin yang digunakan pada penelitian ini adalah, turbin tanpa flow disturber (base turbine), turbin dengan single flow disturber dan turbin dengan double flow disturber. Tujuan penelitian ini untuk mengetahui peningkatan kinerja teknologi turbin PLTAL untuk kecepatan arus rendah. Metode yang digunakan dalam penelitian ini adalah eksperimen karena lebih mendekati kondisi aktual. Adapun tahapan kajian eksperimen yang telah dilakukan yaitu, studi literatur dan survei lokasi eksperimen, perancangan desain dan fabrikasi model turbin, instalasi model turbin di open channel, kalibrasi alat ukur, pengujian model turbin dan analisis hasil data. Hasil akhir yang diperoleh dalam penelitian ini adalah, turbin dengan double flow disturber mampu meningkatkan ketiga kinerja turbin yang lebih baik yaitu, self-starting, daya mekanik dan efisiensi.

Asosiasi Energi Laut Indonesia (ASELI) in 2014 provided the results of the ratification of the potential of ocean current energy in Indonesia of 17,989 MW. The amount is quite large for the results of several potential points in the territory of Indonesia. However, the potential of ocean currents in Indonesia has not been utilized optimally, even though the technology of the current turbine is developing rapidly in the world. The technology of current turbine that is already available in the world cannot be applied in Indonesia, because the condition of the waters in Indonesia is classified as low current speed, unlike in some countries in the world that are classified as high current speed. Therefore, the turbine is needed that can work in the condition of the territorial waters in Indonesia, in general with low current speed. Therefore, the turbine is needed that can work in the condition of the territorial waters in Indonesia, in general with low current speed. The turbine used in this study, the turbine without flow disturber (base turbine), the turbine with a single flow disturber and the turbine with double flow disturber. The purpose of this study was to determine the increase in the performance of the turbine for low current speeds. The method used in this study case is an experiment because it is closer to the actual conditions. The stages of experimental studies that have been carried out are, literature studies and surveys of experimental sites, design, and fabrication of turbine model design, installation of turbine models in the open channel, calibration of measuring instruments, testing of turbine models and analysis of data results. The final results obtained in this study are, turbines with double flow disturber can improve the three turbine performance better, namely, self-starting, mechanical power and efficiency.
