Urban flooding is triggered by the conversion of land use functions that were originally open areas into residential land areas. Therefore, this study aims to determine the existing condition of drainage channels and solutions to overcome problems in drainage channels in Tampan District, especially on Jalan Manyar Sakti, there is often a puddle of water during rain, because there is a lot of ga…
Based on the S curve on the time schedule for the construction of the D.I Primary Irrigation Network for the Sawah Laweh Tarusan Area in Kab. Pesisir Selatan - West Sumatra can be seen from the plan curve and the realization curve, which shows that the work was completed on time, but the realization curve is below the plan curve, which usually indicates that the work is late. Under these condit…
Faculty of Engineering, University of Riau as an education center has certainly provided parking facilities for the academic community. Faculty of Engineering UR has undergone an increase in the number of academic communities starting from the addition of new departments and study programs. The increase in the number causes inadequate parking facilities, this is evidenced by problems with avail…
Water storage buildings in the form of reservoirs are one alternative to meet the availability of raw water. Setokok Reservoir is located on Setokok Island, Bulang District, Batam City, Riau Islands Province. The effectiveness of Setokok Reservoir is very influential on the activities around the reservoir and on the performance of services to raw water. Therefore, it is necessary to analyze the…
All ofmaterial in the earth has specific restivity value, so that it can be measured with using Geoelectrical equipment. Geoelectrical method uses electric resistivity variation based on the measurement ofpotentials differentiation caused ofthe current injected into the earth. Sofar the value ofmaterial resistivity still known in general, like sand: 10 -5000 ohm.m, sand saturated: 1 -1750 o…
The aim ofthisresearch is to leant the influence ofrecycledaggregate with the certain percentage against strength that was produced. Recycled aggregate could be easily obtained in the devastatedarea since there we a large number of debrisfrom buildings. In thisresearch, recycled aggregate will be used to replace apart or the whole gravelsand in mortar, The ratio between cement and sand in …
The objective of this study is to analyze strength and ductility behavior high-strength concrete columns confined high-yield-strength steel by variousyield strength of transverse reinforcement, spacing of transverse reinforcement and shape ofconfinement (circular hoops andspirals). The advantages of thisstudy is to reduce reinforcement detailing, so it can increase workability. Behavior of …
The structure failure in the pavement system always causes damages and makes roadway notfunction optimally. To know the level of existing damage, an investigation to measure the PCI (Pavement Condition Index) is required to be done, in this study we consider the road link ofKuok - Kampung Gadang especially at KM 2. The purpose ofthis study is to know the condition ofthat road using PCI clas…
Mixing time is very important in controlling concrete compressive strength, the longer waktu pengadukan the more concrete compressive strength decrease. This is occored because couldjoint against concrete mixture when it is setting time ofconcrete. In order to control setting time. It is used additive chemical material such asplastiment RTD-01 as solution. In this research, it is obseved t…
ABSTRACT Portland cement represent especial component in concrete technology. Cement process can make worse effect of this global warming and glasshouse so that need thrift of use cement through substitution with waste (pozzolan) as concrete mixes. Dregs is waste of acacia having the nature ofpozzolanik because containing element ofSiC>2 dan CaO which can be used as a substitution cement. …

Peatlands are naturally always wet and moist and will potentially cause various disasters if drained. In restoring the functions of peatland ecosystems as carbon storage, biodiversity storage, water storage, and reducing greenhouse emissions, peatland restoration through good water management is needed. This research was conducted at KHG Bengkalis Island, Bengkalis Regency, Riau Province. For T…
Brittle properties are a crucial weakness of concrete materials used in the world of construction. This encourages the use of additional materials which function to minimize direct collapse due to the brittle nature of concrete. One of the additional materials used is polypropylene fiber. This fiber is a type of plastic that is able to increase and improve concrete properties such as ductility …
The development of community activities in utilizing land to meet their daily needs has an impact on changes in land use in the Batang Sinamar watershed. The change in land use is feared to have the potential for land erosion. This study aims to determine the rate of erosion and the level of erosion hazard in the Batang Sinamar watershed. The USLE and MUSLE erosion prediction models are used to…
