Road damage can be caused by several factors, including water due to poor drainage conditions, pavement construction materials, unstable subgrade conditions, poor compaction processes on the subgrade layer. The author made …
Rainfall measurements at each observation station produce rainfall data point rain is considered to represent the rainfall of a certain radius. Establishment costs, operational costs and difficult natural conditions mean that the limited availability of rain measuring stations in many areas is the main obstacle in providing spatially reliable rainfall data. Supporting instruments that can provi…
This research aims to analyze the characteristics of coastal damage problems and determine the main priority level for coastal areas according to the guidelines of the Minister of Public Works Circular Letter No. 08/SE/M/2010 which occurred in Medang Kampai District, Dumai. The method for analyzing the level of damage to the Teluk Makmur coast uses semi-quantitative qualitative weighting. Spati…
Peatlands on the island of Sumatra have very deep peat thickness and are classified as sapric, hemic and fibric peat types with water absorption levels which are classified as Moderately Absorbent and Slightly Absorbent types. This research aims to analyze the vertical distribution of moisture and peat soil properties in peatlands on the island of Sumatra. This research was carried out using th…
Peat soil abrasion that occurs on the coast of Bengkalis Island is quite worrying coupled with this bogburst event can accelerate the loss of land on Bengkalis Island, if this is left unchecked it will result in a reduction in land area on Bengkalis Island and can reduce Indonesia's territorial boundaries. From the observations in the field, the bogburst caused temporary peat landslides in the …
In general, peatlands in Riau Province consist of mainland (island) and archipelago lands. The island peatlands in Riau Province include Rangsang Island in Meranti Islands Regency and Bengkalis Island in Bengkalis Regency. Rangsang Island and Bengkalis Island are two of the KHG in Riau Province that are located on the coast and facing the Strait of Malacca. Island and archipelago peat generally…
As population growth increases, water demand in Pinggir District also increases. Pinggir District is a division of Mandau District, Bengkalis Regency. So, it is hoped that it will be able to improve services, especially clean water services. This research aims to find out how much clean water demand in Pinggir District and planning transmission pipes. The population projection calculation is ca…
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. …
