Background The purpose of this research was analizing hydrometeorogical parameters (sea surface temperature, ocean currents, and salinity) in Lombok’s ocean and the effect in potential for pearl oyster cultivation based on seasonal patterns in Lombok’s ocean, Nusa Tenggara Barat. The Silver-lip pearl oyster (Pinctada maxima) has a high economic value, but the wild stock of the pearl oyster is very rare resulted and growth reductions in many pearl farming sites. For resolving those problems, choose the right location for pearl oyster with the support of hydrometeorological parameters appropriate quality standards for marine biota are needed. Indonesia has one of the best pearl oyster cultivation, especially in Lombok’s ocean. Research Domain and Data Sources Lombok, Nusa Tenggara Barat Sea Surface Temperature (SST) 115°45'00" - 116°45'00" E coast watch NOAA 08°15'00"-08°48'00" S remote sensing data (sst, ocean ocean currents, salinity currents, salinity) marine copernicus 2006 - 2016 The 9th Asia-Oceania Meteorological Satellite Users’ Conference Jakarta, Indonesia, on 6 – 11 October 2018 Monsoon system in Lombok, Nusa Tenggara Barat (NTB) Monsoons are winds that blow throughout the year and change direction twice a year. There are two main characteristics of the Monsoon climate above, namely the existence of strict differences between wet season and dry season which generally occur in the December, January and February (DJF) periods and June, July and August ( JJA) (Chao et al, 2001). Lombok is Monsoon Rainfall Pattern, The region has a clear difference between the rainy season period and the dry season period then grouped into Season Zone (ZOM), the type of rainfall that is unimodial (one peak of the rainy season, DJF (December-January-February) rainy season, JJA (June- July-August) dry season). The 9th Asia-Oceania Meteorological Satellite Users’ Conference Jakarta, Indonesia, on 6 – 11 October 2018 Research methods Aquatic Conformity Assessment System for Pearl Oyster Cultivation Locations IKK : The suitable pearl oyster cultivation index Ni : bobot x scor Nmax : Total skor This research used remote sensing data in January 2006 until December 2016. The method used to classify each hydrometeorogical parameters based on scoring, then each parameter will be overlay together, so we can get the highest score where indicating the most potential area for pearl oyster cultivation Research methods Aquatic Conformity Assessment System for Pearl Oyster Cultivation Locations No. Kisaran nilai (Scor) Suitable Evaluation/Kesimpulan 1. 85 – 100 % S1 Sangat sesuai (highly suitable) 2. 75 – <85 % S2 Sesuai (suitable) 3. <65 - 74 % S3 Tidak sesuai (not suitable)
