River water resources are developed as an effort to support human life by providing and utilizing water. In practice, planning the development of water resources in a watershed (DAS) requires field discharge data as the main data. However, discharge measurement data in the field is generally limited and the most common data is rainfall data. Therefore it is necessary to transform rainfall data…
The Waduk Buatan built by the government in the 80s is a reservoir for the Ambang and Merbau watersheds located in Lembah Sari Village, Rumbai Pesisir District, Pekanbaru City, which was initially used as a source of irrigation water for the surrounding area's rice fields, which was later converted into a PDAM raw water source. The basic contour of The Waduk Buatan is needed to determine the ma…
The development of construction needs to pay attention to the condition of the subgrade so that it can carry the load above it. Peat soil is known to have high moisture content, organic content and pore number. Therefore, it needs to be stabilized before being used as a subgrade. Microbial-induced calcium carbonate (CaCO3) precipitation is an environmentally friendly soil improvement that can …
Mandau District is the largest economic and market center in Bengkalis Regency. Buying and selling activities in the Mandau Market area cause crowds of people shopping, thus affecting the level of service for pedestrian facilities. This research aims to determine the characteristics and level of service of pedestrian facilities in the Mandau Market area. This level of service refers to Minister…
Peat soil has low strength, high compressibility, and high moisture content. Therefore, peat soil must be stabilized so that it can be used as a base for construction. MICP is an environmentally friendly soil stabilization method using bacteria. The bacteria will produce calcium carbonate that will fill the space between the peat soil voids. The use of sand as an additive is considered to impro…

Garuda Road Pekanbaru city is a local road that serves local transportation with short distance travel characteristics, has a length of 2,600 meters and a width of 5 meters. 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…
