      Abstract
      Teluk Jakarta terletak di pantai utara Pulau Jawa merupakan muara bagi 13 sungai besar di Jakarta, Bogor, Depok, Tangerang, dan Bekasi. Berbagai aktivitas yang melibatkan pemanfaatan perairan baik teluk maupun sungai dapat menyebabkan penurunan kualitas perairan dan pengayaan nutrien. Salah satu akibat pengayaan nutrien yaitu peningkatan nutrien seperti fosfat dan nitrat yang dapat memengaruhi produktivitas perairan. Penelitian ini bertujuan menganalisis sebaran konsentrasi fosfat dan nitrat di Teluk Jakarta secara spasial dan temporal. Pemantauan kualitas air dilakukan antara tahun 2012 hingga 2019 sebanyak delapan kali pengamatan dari 23 stasiun. Penentuan 23 stasiun berdasarkan keterwakilan wilayah Teluk Jakarta. Berdasarkan kandungan fosfat dan nitrat, perairan Teluk Jakarta terrmasuk subur. Pola sebaran spasial fosfat dan nitrat konsentrasinya lebih tinggi di sekitar pantai dan semakin rendah seiring mendekati mulut teluk. Secara temporal, konsentrasi fosfat dan nitrat menunjukkan perbedaan yang signifikan cenderung meningkat dari tahun ke tahun.
       
      Jakarta Bay is located on the north coast of Java Island and is the mouth of 13 major rivers in Jakarta, Bogor, Depok, Tangerang, and Bekasi. Various activities that involve the use of waters, both bays and rivers, can cause a decrease in water quality and nutrient enrichment. One result of nutrient enrichment is an increase in nutrients such as phosphate and nitrate which can affect water productivity. This study aims to analyze the spatial and temporal distribution of phosphate and nitrate concentrations in Jakarta Bay. Water quality monitoring was carried out between 2012 and 2019 in eight observations from 23 stations. Map of 23 stations based on the representativeness of the Jakarta Bay area. Based on the content of phosphate and nitrate, the waters of Jakarta Bay are considered fertile. The pattern of spatial distribution of phosphate and nitrate concentrations is higher around the coast and lower as they approach the mouth of the bay. Temporally, the concentrations of phosphate and nitrate showed significant differences which tended to increase from year to year.
