Climatic conditions in the Sibinail watershed which have quite high rainfall often cause flooding. Frequent flooding results in economic and social losses for the surrounding community living on the banks of the Sibinail River. In addition to rainfall factors, flooding that occurred on the Sibinail River was also influenced by poor river cross-sectional conditions. Therefore it is necessary to …
The large number of puddles in Dumai City makes decision makers hesitant in making decisions. The most appropriate priority for inundation requires computer-based accurate data as the basis for every decision to be made. This research was conducted by survey and literature method which aims to identify parameters that influence the priority value of handling by the Analytical Hierarchy Process …
Riau is an area with 3.867.413 Ha of peat lands, it reaches about 60,08% of total peat area on Sumatera Island. The leverage of peat becomes new problem to several aspects including, providing urban residences, roads, and agricultural infrastructures. The main problems that need to be solved in constructions on peat are the bearing capacity and stabilization of foundations. Therefore, a specifi…
Soft soil is related to soils which if not recognized and carefully investigated can cause problems of instability and long-term decline that cannot be tolerated, have low shear strength and high compressibility. The increase in the amount of waste that was not followed by improvement and improvement of waste management facilities and infrastructure resulted in the problem of garbage becoming m…
This study aims to evaluate the effect of two rejuvenating materials, namely: Termite and PEN 60/70 Asphalt Residue on the performance of hot paved mixtures using the Reclaimed Asphalt Pavement (RAP), to obtain the optimum composition of the fluxing agent used. The methodology used was experimental in the laboratory, namely by comparing the performance of paved mixtures using Reclaimed Asphalt …
Rangsang Island is one of the 4 main islands in the Meranti Islands Regency. The location of this island is very strategic because it is directly adjacent to the Malacca Strait so that the island has very high economic value. Abrasion that occurred on Rangsang Island resulted in a lot of losses suffered by people living on the island's coast, including eroded coconut plantation land, damaged do…

This study deals with the application of ERT (Electrical Resistivity Tomography) for analysis of peat characteristics and carbon stocks. The use of ERT in this activity was assisted by GPS RTK to investigate find out the coordinates and elevation of the surveyed points, and hand drill to investigate the depth of the peat. The use of the ERT in the field applied the transect method, so that the…
Activities on the critical path have potential to delay the completion of a project. Critical path has a dominant risk and influential on the next job if it is late to start and finish. Activities on tank repair projects has a series of critical path of high-risk.The objectives of this research are to identify, analyze and mitigate the risk factors for delays in the tank repair project locate…
One of the problems of agricultural land productivity in Indonesia is the poor irrigation infrastructure. In order for the irrigation infrastructure to run properly it is necessary to carry out operations and maintenance periodically. The area of irrigation network in Siak Regency especially block B, C and D is about 5,000 Ha which is one of the biggest commodities in supporting PDRB in Siak Re…

Experts who are respondents are policy makers, actors, consultants and experts who are directly involved in Dumai City SPAM development. The AHP method using the Expert Choice 2000 application is used to determine the criteria and sub criteria o…
Peat has different characteristics compared to clay. It is physically recognized as soil with organic materials content, great amount of water, high void ratio, and the existence of fibers. However, it technically has high compressibility and low shear strength. To identify how big is the influence of compression behaviour towards the increment of peat`s shear strength, some consolidation and v…
