Abstract
Sebagian besar energi listrik yang kita nikmati saat ini dihasilkan oleh pembangkit termal dari energi bahan bakar fosil. Namun energi fosil jumlahnya terbatas dan harganya fluktuatif setiap waktu, serta menghasilkan polusi lingkungan. Indonesia sebagi negara maritim memiliki potensi energi dari laut yang cukup besar. Sayangnya hanya sedikit sekali jumlah energi yang dapat termanfaatkan menjadi energi listrik. Air laut memiliki potensi untuk dimanfaatkan sebagai elektrolit untuk reaksi sel volta pada sel bahan bakar (fuel cell). Pada tugas akhir ini didesain sebuah alat konversi energi listrik berbasis sel volta yang menggunakan elektroda seng (Zn) dan tembaga (Cu) serta elektrolit air laut dengan kadar salinitas dan oksigen terlarut tertentu. Sampel air laut yang digunakan berasal dari perairan Selat Madura, di Pantai Batumalang, Bangkalan, Madura. Pengujian dilakukan terhadap beberapa faktor seperti salinitas, temperatur, ukuran elektroda, laju aliran air, serta penyusunan seri dan paralel. Daya maksimum didapatkan pada ukuran elektroda 5x8 cm, laju aliran 8,5 ml/s, salinitas 3,75%, kadar oksigen 5,6 m/liter, serta temperatur 31o C (suhu ruang), yaitu sebesar 2,16 miliwatt untuk satu buah sel pembangkit. Sehingga untuk menghasilkan keluaran sebesar 600 watt maka dibutuhkan sel yang diseri sebanyak 59 buah dan masing masing diparalel sebanyak 82 buah. Efisiensi yang diperoleh dari potensi energi yang mungkin dihasilkan masih sangat rendah yaitu sekitar 0,9%.

Most of the electrical energy we use today are produced by thermal generators from fossil fuels. As we know, fossil energy are limited and their price is fluctuative as time goes, besides causing harm to environment. Indonesia as a maritime nation has a large potential source of energy from ocean. Unfortunately only a few quantity of those energy are successfully converted into electrical energy. Seawater itself has apotential to be used as an electrolyte for a voltaic cell reaction in a fuel cell. In this final project, an energy conversion device is designed using voltaic cell as a priciple that uses two different electrode, Zinc (Zn) and Copper (Cu) and seawater as electrolyte that contains salinity and dissolved oxygent. The seawater sample is taken from Madura Strait, along the coast of Batumalang Beach, Bangkalan, Madura Island. The test is carried in some conditions, such as variations in salinity, temperature, flow rate, and cell connection in series and parallel. The maximum electrical power acquired at 5x8 cm electrode size, 8,5 ml/s flow rate at 3,75% salinity, 5,6 mg/litre dissolved oxygent,and ambient temperature 31o C. At this specification, the series of cells needed for desired specification is 59 cells, while each series must be parallelled up to 82 cells. The efficiency gained from the potentially generated energy is still very low at 0,9%.
