Abstract
Penelitian ini merupakan studi eksperimental terhadap sistem pembangkit listrik berbasis turbin arus laut tipe axial flow yang dilengkapi dengan nozzle diffuser dan dikopel langsung dengan Permanent Magnet Generator (PMG) menggunakan sistem transmisi mekanik berupa pulley dan V-belt. Sistem ini dirancang untuk mengkonversi energi kinetik dari arus laut menjadi energi listrik secara efisien tanpa memerlukan gearbox, yang lazimnya menambah kompleksitas, berat, serta biaya perawatan. Eksperimen dilakukan di lingkungan laboratorium dengan menggunakan motor DC sebagai penggerak simulasi arus laut. Pulley turbin berdiameter 27 cm dihubungkan dengan pulley PMG berdiameter 7,6 cm, menghasilkan rasio transmisi sekitar 3,55:1 untuk meningkatkan kecepatan putaran pada PMG. Pengujian dilakukan dalam dua kondisi: tanpa beban dan berbeban, menggunakan lampu pijar 100 Watt sebagai beban tetap. Hasil pengujian menunjukkan bahwa sistem mampu menghasilkan tegangan hingga 18,9 Volt dan daya maksimum mencapai 95 Watt. Efisiensi sistem cenderung meningkat seiring naiknya kecepatan putar, dengan performa terbaik terjadi pada RPM tinggi yang dicapai melalui rasio pulley. Penelitian ini membuktikan bahwa rancangan sistem sederhana dan ringan ini tidak hanya efektif dalam menghasilkan energi dari arus laut berkecepatan rendah, tetapi juga layak diterapkan di daerah pesisir terpencil sebagai solusi energi terbarukan yang andal dan hemat biaya.

This research presents an experimental study on a marine current power generation system utilizing an axial flow turbine equipped with a nozzle diffuser, directly coupled with a Permanent Magnet Generator (PMG) via a mechanical transmission system consisting of pulleys and a V-belt. The system is designed to convert the kinetic energy of ocean currents into electrical energy efficiently, without the need for a gearbox, which typically adds complexity, weight, and maintenance costs. Laboratory-scale experiments were conducted using a DC motor to simulate ocean current flow. A 27 cm turbine pulley was connected to a 7.6 cm PMG pulley, producing a transmission ratio of approximately 3.55:1 to increase rotational speed at the PMG. The system was tested under two conditions: no-load and load conditions, with a 100-watt incandescent lamp serving as the fixed electrical load. The results showed that the system could generate voltage up to 18.9 Volts and a maximum output power of 95 Watts. System efficiency tended to improve with increasing rotational speed, with optimal performance achieved at higher RPMs facilitated by the pulley ratio. This study demonstrates that the simple and lightweight system design is not only effective in harnessing energy from low-speed marine currents but also feasible for implementation in remote coastal areas as a reliable and cost-effective renewable energy solution.
