The parameters are …
Forest and peatland fires cause haze disasters that threaten aspects of human life at the local, national, regional and even global level. Loss of vegetation and the opening of peat swamp forests cause flooding in the rainy season, reduce carbon sequestration thereby increasing the greenhouse effect, and forests will lose their climate regulation function. The purpose of hydraulics modeling re…

This research is conducted to analyze the critical success of contractor’s performance in implementing this long segment preservation program. Contractors …
Reducing the risk of forest fires that have a negative impact, it is very important to study and improve the patterns and practices of forest resource management and communities living around the forest. The pattern and practice of forest resource management and the community around the forest must be formulated in a forest fire prevention strategy. This study aims to: (i) explore information o…
One of the most important components to prevent the occurrence of fires in Tropis peatland is groundwater level. Monitoring groundwater level directly in the field requires a high cost. Therefore is Background, this study will make Hydrological Model for Prediction of Groundwater Level in Tropis Peatland as Fire Mitigation Efforts based on rainfall data and groundwater level data. This reseac…
The availability of wood with suitable properties for bridge construction has become increasingly scarce. The reason is the decreasing size of the forest as a source of timber. To anticipate this, innovation is needed by utilizing wood which is still widely available but does not meet the requirements. In this regard, the purpose of this study is to examine the behavior of merau wood and wood c…
The availability of water in the Sub DAS Kampar Kanan which has an important role in addition to being a catch for the Kampar river as well as where the PLTA Koto Panjang hydropower reservoir is located. The hydrological model to be used is the GR4J Model (Genie Rural a 4 parametres Journalier) developed by Perrin, and IHACRES model developed at Australian National University (ANU). The GR4J mo…
This study is intended to analyze the steel frame construction if the work is done in stages. Birandang Bridge is chosen as an example, one of the steel frame bridges in Riau Province with a span of 140 m. The Finite Element models of the bridge is modeled using sap2000 based on the bridge data. Loading variations are applied on 2 different bridges modeling to measures the Moment, Axial Force a…
Traffic accidents in the period of five years from 2013 to 2017 there are 85% of cases of traffic accidents occur in Mandau and Pinggir with the main road segment is the Sumatra 112 km and 126 km crossing roads, so it is very necessary to deal with prevention accident. This study aims to determine the number of traffic accident accidents with the EAN (Equivalent Accident Number) approach, and t…
The aim of this study is to analyze the value of building investment as a monitoring and evaluation of building investment to determine the size of man-made resources that have been built in watersheds that need to be protected from damage caused by watershed degradation and use of regional space to determine changes in protected area conditions and related cultivation areas there is no tendenc…
The Deep Embedment (DE) method is a strengthening method, in which additional shear reinforcementwere installed in the core reinforced concrete beam. The purpose of this study is to analyze the shear capacity of existing reinforced concrete beams without additional shear reinforcement (embedment)andto analyze the shear capacity of reinforced concrete beams reinforced by the deep embedment metho…
Indragiri Hulu is one of the regencies in Riau Province which has lowland geographical conditions with little hills, the condition of buildings in Indragiri Hulu Regency on average only two floors to the fourth floor. The location and condition of the earthquake in this regency are not included in earthquake prone conditions, but with earthquakes that cannot be predicted to occur. For this reas…
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…
