Abstract

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.

Abstract

Utilization of marine natural resources at this current becoming one of the option thatis used by several Indonesian regions as motors of regional development. One of thenatural resources potential is tin mining. Tin mining over the ocean not only provideseconomic value, but also resulting negative impacts on marine waters. The alleged ofnegative impact is the increasing of suspended sediment in the waters due to leaching ofmining activities on the ship. Current circulation patterns that generated by tidal ofPulau Rangsang waters Regency of Meranti Islands, when the tide to ebb is heading tothe Southward and when the ebb to tide is heading to northward. The resultant ofcurrents circulation tend to align with the mainland of Pulau Topang. Suspendedsediment transport generated by ocean currents, showing the distribution of thesuspended sediment concentration of 0.08 kg/m3 or 80 ppm spreads about 2 km fromthe material source.

Abstract

Improving of water quality from siak river that have been used for long time by communities around the river for many purposes such as drinking water and washing has been done by implementing various method such as filtration, coagulation, aeration absorption. Each method has specific characteristic and advantages. Filtration with sand and gravels can decrease concentration of total suspended solid, Fe, Mn and organic material (KMnO4). Coagulation with alum (Al2SO4) can decrease TSS Concentration, Fe, Mn, NO3, NO2, KMnO4, coliform and coli fecal. Furthermore, aeration with a oxygen can decrease TSS concentration, TDS, Fe and Mn. While absorption whit active carbon can decrease concentration of TSS, Mn and Fe. After the four methods had been studied, the best result was obtained through combination of four methods (filtration, coagulation, aeration and absorption).

Abstract

One of the forest functions is the protection for water ecosystem along a watershed. Theactivities of extensive acacia logging area near the watershed of Sipatak by PT. SumateraSylva Lestari currently have not paid attention on the environmental condition, especiallythe hydrologic aspect. The present research sought to investigate the effect of the extensivelogging acacia on the flood hydrographic characteristic. The research was expected to comewith the proper acacia logging area. The land coverage and curve number analysis wereperformed using software program ArcView GIS 3.3 which was based on Table SCS CurveNumber. The average rain of the watershed was calculated using Polygon Thiessentechnique and the plan maximum daily rain was obtained from a frequency analysis towardthe average rain of the watershed. The hydrographic units was obtained from 10 floodincidences using Collins’ technique. The scenario of the forest logging pattern was madeaccording to the prevailing provision at PT. Sumatera Sylva Lestari. The floodhydrographic analysis was performed using Software HEC-HMS 2.2.2 by doing acalibration and verification to obtain the watershed parameter which would be used in theflood hydrographic simulation resulting from the logging. The initial value of the subwatershed of Sipatak was 78.558. The logging at sub watershed of Sipatak up to 79.496%resulted in the increase of CN to be 83.49. The increase of the CN resulted in the increaseof the peak debit up to 71.60% and the runoff volume was 71.04%. The trend line of peakdebit increase and the runoff volume resulting from the forest logging depended on thelogging forest area and the rain input. To avoid the over capacity of the watershed ofSipatak, the logging area should be 120.30 hectare or 32.69%.
