The research were conducted in River estuary of Rokan, Riau Province on Mei 2014. Sedimentation analysis were investigated by various method i.e, sedimen grain-size analysis, Total suspended solid analysis, mechanism of particle disseminated, river’s sediment transport analysis, longshore sediment transport analysis, coastline chance analysis and absolute sedimentation velocity. The research was aim to explained sedimentation procces covered mechanism of sediment transport and sedimentation rate, and then could be able to gave the solution for preventive study of River estuary of Rokan Sedimetation. The result of grain-size analysis showed that mean size were dominated by find sand, sorted by poorly sorted. The disseminated of sediment in deep water was tended to very fine skewed dan skin-deep was very coarse skewed. Mechanism of disseminated particle result when tide, find sand sediment was transport as 128,52 m to the south-east in 23,33 minute. On the contrary to the northwest as 88,10 m in 16 minute. Very find sand was transport as 82,59 m to the south-east in 15 minute at tide and on the contrary to the northwest as 67,12 m in 11,27 minute. Total Sediment Transport Formulae showed 137.023 m3/year of sediment transport was occurred, while longshore sediment transport was 33.616.808,53 m3/year at the River estuary of Rokan. The coastline chance showed addition of land at the estuary was 240.096.862,77 m2 , accretion was 280.492.425,46 m2, and abration was 27,935,195.86 m2. From sediment total calculation in a year comparing by 60 years accretion showed, the absoluted sedimentation velocity was 0,19 cm/year. It was low, so that concluded the contriction of estuary by accretion.

Aceh Waters has a very potential biological resources, that made the cathing rates become the potential activities. Skipjack Tuna (Katsuwonus pelamis) is one of the potential fishing due to high economic value and its high distributions. The abundant of Skipjack Tuna was affected by the productivities of chlorophyll-a. this study aims to investigate the effects of chlorophyl-a on the catch rates of Skipjack Tuna in Aceh waters during September 2017. Survey methods were applied for this study by conducting three scientific research cruises to 32 fishing ground stations. The results of satellite images and catch retes were generate by using overlay method. Satellite images data on September 2017 shows that the average of chlorophyll-a is around 0,23 mg/m3, with the variations 0,10 – 1,30 mg/m3 that distributed around Aceh Waters and Selat Melaka. And the biggest catching of Skipjack Tuna achieved on the third trip where the chlorophyll-a is around 0,17mg/m3 and the total of catch rates is 7,480 kg.
