Derajat keasaman (pH diukur dengan pH meter Cyber Scan 300. Kadar oksigen terlarut diukur dengan menggunakan metode Winkler. Kadar fosfat, nitrat, dan silikat dianalisis menurut metode Strickland dan Parsons. Metode penelitian yang digunakan adalah pengambilan air laut dari lapisan permukaan (5 m, termoklin (15-150 m dan dibawah termoklin (100-300 m pada 19 stasiun penelitian. Parameter yang diteliti meliputi fosfat, nitrat, dan silikat serta parameter kualitas air yaitu oksigen terlarut, dan keasaman (pH. Tujuan penelitian tersebut untuk mengkaji kualitas air ditinjau dari kandungan zat hara yang merupakan indikator kesuburan perairan serta faktor-faktor yang mempengaruhinya di perairan Lamalera, Nusa Tenggara Timur. Penelitian oseanografi di perairan Lamalera, Nusa Tenggara Timur telah dilakukan pada bulan Juli 2011. Sebaran Horizontal Zat Hara di Perairan Lamalera, Nusa Tenggara Timur (Horizontal Distribution of Nutrients in the Waters Lamalera, East Nusa TenggaraДirectory of Open Access Journals (Sweden)ДЇull Text Available Perairan Lamalera, Nusa Tenggara Timur merupakan perairan yang sangat penting karena kondisi oseanografinya yang dipengaruhi daratan, Laut Sawu, dan Samudera Hindia sehingga kaya akan sumberdaya laut. This paper will uncover the potential of OTEC in East Nusa Tenggara province so it will bring possibility to build an OTEC power plant in the future. Ocean Thermal Energy Conversion (OTEC) is one of the renewable source method from ocean. In addition, another renewable source that not yet known is from the ocean itself. Renewable sources for power plant have a good potential to work with, in example wind power, solar power, geothermal, or biomass. Power Plant with renewable source placement in East Nusa Tenggara Province or smaller district need to be prioritise to cope with the low electrification ratio. This electrification ratio describes the level of availability of electrical energy for the community. However, East Nusa Tenggara Province electrification ratio only around 58.64%, this is the second lowest ratio in Indonesia. The Growth of the economic and population in Indonesia increasing the demand of the electricity annually, in 2015 alone electricity consumption in Indonesia reaching 200 TWh and will continue increasing every year. Indonesia has more than 17000 islands with 70 per cent of the region is ocean. Indonesia is the largest archipelago country in the world, located between Indian Ocean and Pacific Ocean.
