Abstract

The clean water obtained by the people of Kecamatan Lubuk Dalam is still very minimal. This is because the groundwater source located in Lubuk Dalam does not qualify as clean water. So far, the people of Kecamatan Lubuk Dalam utilize watersource from rain water and drilled well. Rainwater that is accommodated by the community is not able to meet the needs of the community during the dry season, while the groundwater source obtained from the well has a poor quality so it is not good for public health. Due to the growing progress of Kecamatan Lubuk Dalam, the Siak regency government is seeking to build a clean water treatment plant deep in order to meet the water needs of the local community. The new will be built in the area of LubukDalam, a source of water obtained from the Sungai Basas, the Siak River in the Koto Gasip area.Keywords:, clean water, distribution, , PDAM , EPANET

Abstract

Transformation process Rainfall-runoff is a scientific process which very complex. This complexity process cause of two factor, that are Watershed variability sistem  and  input parameter whick has high variability space and time. So for cope with this komplex process used rainfall-runoff modeling. Model that the used expected could approach Watershed  characteristic. A Rainfall-Runoff model is HEC-HMS. HEC-HMS accurate  for modeling the event a moment such as flood. This modeling will be used at the Duri Canal Watershed in this  study divided into 29 cathment area, with total area 448.4624 km2.   The results of the HEC-HMS modeling in 2002 obtained Qp is 1627.3 m3/sec, this output will calibration with HSS Nakayasu method and obtain Qp 1669.32 m3/sec caused by rainfall 150 mm. Whereas for the 2012 HEC-HMS modeling obtained Qp is 1231.7 m3/sec and for calibration HSS Nakayasu method obtained Qp is 1193.55 m3/sec caused by rainfall 107.5 mm. The result showed nearing values. However HEC-HMS and HSS Nakayasu have different peak time (tp). HEC-HMS have tp at the eleventh o’clock whereas HSS Nakayasu method have tp at the fourth o’clock. This different caused devide of cathment area at HEC-HMS modeling. Keywords : Model, Rainfall-Runoff, Calibration, HEC-HMS, HSS Nakayasu

Abstract

The length’s advisability of the berth can be seen from the Berth Occupancy Ratio (BOR). The pour liquid berth (Berth B) in Dumai’s harbor is one of the berth which has a higher activity and the ships that come increasing everyday. The increasing ships in Berth B need a project to know the value of visiting ships and the value of BOR in short term, middle term and long term. Project is done in order Berth B can hold the ships that will tether by adding the length of berth.The value of BOR in short time projection until 2019 is 75,86 % and the number of ships are 744. To fulfill The Standard Of Managing Director Of Marine in 2011, the value of BOR was 69% therefore the berth should be lengthened about 70 meters. In 2019 the short time projection the length of Berth B becomes 870 meters.Based on project result the visiting ships are 984, the value of BOR in middle term is 87,94% in 2024. To fulfill the value of BOR which is 69%, the Berth should be lengthnened formerly 870 meters become 1100 meters.The long term projection until 2029 the value of BOR is 83,71% with the number of visiting ships 1224. To fulfill the value of BOR that is 69%, the Berth should be lengthnened around 220 meters.

Abstract

There are several problems related to water resources such as floods and drought. One of the critical issue is drought. Drought is a nature phenomenon which is considered as common dangers which occurs in accordance of climate cycle related to hydrological cycle that affected by rainfall. Drought that affected only by rainfall is meteorological drought which is an early indication of drought. Based on the large impact, it is necessary to analyze index of dryness to find out the level of dryness as the early warning of further droughts. The location of the research was the Batang Anai watersheds which is one of water source of agricultural sector in Sumatera Barat Province. Standardized Precipitation Index (SPI) was one of the methods to analyze drought index in an area. The calculation was done based on rainfall data of half monthly period and monthly period from 1997 to 2016 on every rain station in DAS Batang Anai. The result of SPI drought index was correlated with Indian Ocean Dipole (IOD) phenomenon and then was mapped using ARC GIS software with tools Polygoon Thiessen. The final result of this research showed that in half period the highest value of drought index was -2,3811 (January, 1st periode, 2013) with extreme drought classification. While in monthly period, the value of drought index was -1,9183 (January, 2012) with very dry classification. This research also showed the suitability of SPI drought index with IOD drought phenomenon which has suitable average 70,14%.Keywords : Drought index, Standardized Precipitation Index, GIS, Indian Ocean Dipole

Abstract

Land use change in the Petapahan Watershed will increase the flow of the surface. The surface flow will increase the amount of soil erosion and sediment transport capacity. Sediment transport will enter the Petapahan Reservoir, so that will lead to silting on thePetapahan Reservoir. It will have an impact on the function and effective life of the reservoir. The USLE method was used to estimate erosion in the Petapahan watershed. GIS was used to predict the value of USLE parameters. The result of analysis shows thatErosion occurring in Petapahan Watershed is in low grade (15 - 60 ton/ha/year) and the potential of erosion that goes to Petapahan Reservoir is 294,8287 ton/year.Keywords: land use, erosion potential, USLE, GIS
