N2 - As an inlet of Sentani lake, Kamp Walker and Hubay rivers have a different environment characteristic, i.e. Kamp Walker has a proximate inhabitant, while Hubay has a relatively more natural environment. In this study, we conduct measurement of magnetic susceptibility, Fe content and morphology of magnetic mineral extracted from the two rivers surface sediment. The magnetic susceptibility of low frequency (χlf) of sediment samples from the two rivers are varies from 11.11 × 10-6 kg/m3 to 24.96 10-6 kg/m3 for Kamp Walker with dependence frequency susceptibility (χfd) from 0.031% to 0.367%. Meanwhile, for HubayRivers we find the χlf varies from 4.56 × 10-6 kg/m3 to 16.93 × 10-6 kg/m3 and χfd from 0.104% to 1.033%. Fe content of the sample from the two river are also has a different average i.e around 60% for Hubay and 50% for Kamp Walker, that may because of the source of magnetic minerals on sediment are mainly a lithogenic magnetic mineral in Hubay, and anthropogenic magnetic mineral in Kamp Walker. The morphology of magnetic mineral, based on the SEM image shows a rounded and crystalline shape.
