Abstract

Sedimen dasar diambil dari estuari Banjir Kanal Barat Semarang. Metode pengabuan digunakan untuk menentukan  karbon organik dan fosfor organik. Hasil penelitian menunjukkan bahwa konsentrasi karbon organik berkisar antara 0,07-0,71% dengan nilai rerata 0,34% dan konsentrasi fosfor organik antara 1,0-3,4 µmol.gr-1dengan nilai rerata 1,98 µmol.gr-1. Hasil perhitungan rasio OC/OP menunjukkan kisaran 2,3-358 dengan nilai rerata 169. Sumber utama material organik dalam sedimen berasal dari daratan dan unsur P lebih reaktif daripada karbon. Keberadaan OC tidak langsung menentukan distribusi OP. Selain organik karbon, distribusi OP dipengaruhi oleh jenis sedimen dan parameter lain seperti arus dan kedalaman. The bottom of sediment is taken from the estuary Banjir Kanal Barat, Semarang. Spying method used to determine organic carbon and the organic phosphorus. The results showed that the concentration of organic carbon ranged between 0.07-0.71 %  with an average value 0,34% and concentration of organic phosphorus between 1,0-3,4 µmol.gr-1 with an average value 1,98 µmol.gr-1. OC / OP ratio calculation results show the range of 2,3-358 with mean value 169. The main source of organic material in the sediment comes from the teresstrial and the P element is more reactive than carbon. The existence of OC indirectly determines the distribution of OP. In addition to organic carbon, the OP distribution is influenced by sedyment type and other parameters such as current and depth.
