The purpose of this study was to determine the levels of heavy metals in sediments and to assesses the sediment quality based on an index analysis approach. Sediment samples were collected from five different stations located along the coast around Ternate City waters. Heavy metal content was measured using Atomic Absorption Spectrophotometer (AAS). The results showed that mercury levels ranged from: 0.592-3.571 mg/kg, Lead: 10.4-12.4 mg/kg, Cadmium: 0.095-0.298 mg/kg and Copper: 0.713-40.494. The average levels of Pb, Cd and Cu are still lower than the sediment quality threshold values, exception Hg. The results of the index analysis showed that the average value of enrichment factors of Hg, Pb, Cd, Cu are 786.162, 104.511, 118.195 and 30.810 (no enrichment to very high enrichment), contamination factors are 4.363, 0.568, 0.653 and 0.208 (no contamination to slight), geo-accumulation index are 1.291, -1.404, -1.288 and - 4.586 (unpolluted to moderate polluted) respectively. Based on the pollution load index value (PLI <1), sediments in these waters are categorized as not yet polluted by Hg, Pb, Cd and Cu.
