The aim of this resea…
ABSTRACT Rainfall is one of the important parameters in water resources planning and management. This study aims to model rainfall in Siak District using Neyman-Scott Rectangular Pulse modeling (NSRP). NSRP forecasting is used to generate low-timescale rainfall data. The results of NSRP modeling carried out Mean Absolute Error (MAE) testing get a value of 0.051 mm which is close to zero. This …
ABSTRACT Traffic accidents are a problem that often occurs on the highway. Traffic accidents cause negative impacts that are very detrimental, including spending costs when an accident occurs and the worst impact is causing fatalities. The purpose of this study was to determine the characteristics of accidents and the amount of traffic accident costs on road section Batas Kabupaten Kampar – …
ABSTRACT Concrete in a seawater environment is prone to damage due to the high salt content in seawater. Seawater intrusion causes salt crystallization in concrete pores. tidal conditions resulting in wet-dry cycles on the structure accelerate the crystallization process. Therefore, the characteristics of concrete will be studied using shell powder and silica fume as a substitute for cement to…
ABSTRACT One of the efforts that can be undertaken in coastal erosion mitigation is the construction of coastal protection structures. Coastal buildings serve as protection for coastal areas from wave potential and sediment transport. However, over time, coastal protection structures will experience damage due to erosion and waves. The damage that occurs to coastal buildings can range from…
ABSTRACT The oil palm plantation landscape of PT Bumi Palma Lestari Persada (BPLP) is an area where there is a peat dome in the Sungai Enok-Sungai Batang KHG, which plays an important role in water treatment to maintain the peat ecosystem. BPLP also builds many canals, which if not managed properly can cause peatlands to continue to degrade. Good water management is the key to environmentall…
ABSTRACT Time history analysis is a process of analyzing the structural response to dynamic loads that vary over time. The dynamic load applied in this analysis is in the form of earthquake time histories. In Indonesia, this analysis method faces limitations due to the availability of earthquake data. However, this constraint can be overcome by using earthquake data from other regions, althoug…
ABSTRACT Selat Guntung is a village located on the outskirts of the Siak river with a rainfed agricultural system, where the main source of agricultural water comes from rainfall and depends on rainfall so that during the dry season agricultural rice fields experience a shortage of water which affects crop production. The irrigation of the Selat Guntung is affected by fluctuations in the water…
ABSTRACT The Peat Hydrological Unit (PHU) of the Enok River and Batang River is one of the PHUs in Riau Province which is located in Indragiri Hilir Regency. This district has a high rate of land clearing for plantations and has many canals, if not properly controlled it can cause peatlands to degrade. Good water management needs to be done to keep the peat moist by knowing the water potential…
ABSTRACT ABSTRACT ABSTRACT ABSTRACT ABSTRACT ABSTRACT Sail River is one of the rivers that flows in Pekanbaru City, Riau Province. One of the problems that often occur in rivers is sedimentation. Sedimentation that takes place continuously at the bottom of the river will experience siltation of the river so that it has the potential for flooding due to reduced river storage capacity. This stud…
ABSTRACT Desa Banglas Barat, Kabupaten Kepulauan Meranti is one of the villages that have clean water problems when the dry season arrives. This is because the availability of raw water that can be used by the community only comes from rainwater. Geological conditions in Desa Banglas Barat with a pH ranging from 3.1-4.0 and high acidity cause the condition of groundwater to be unfit for consum…
ABSTRACT Clean water is one of the most vital needs for all humans or living things. Because all residents' activities have various aspects of life wherever they need clean water. Referring to the Pariaman City Spatial Plan (RTRW) for 2022-2042, it is necessary to project the need for clean water for the residents of Pariaman city. Domestic clean water needs are water needed for households. Wh…
ABSTRACT Rainfall measurements at each observation station are point rainfall data, which are considered representative of rainfall for a certain radius. Due to high establishment and operational costs and difficult topography for mountainous areas, the number of rain observation stations is limited. Overcoming the lack of rain stations to provide reliable rainfall data can be achieved by usin…
The FEMA P-58-5 method is a method used to evaluate the performance of a building structure using a probability approach. based on the output obtained from PET (Performance Estimation Tools). The purpose of this research is to obtain the performance of the building structure simulated by the influence of the planned earthquake (2017 Earthquake Hazard Map). This research is using the provis…
The presence of peatland in Indonesia has an important role for the sake of environmental perseverance globally. Land fire does not only occur in dry land, but also in wet land. Rokan Hilir Regency is the contributor of forest fire and peatland fire until peatland degradation in Rokan Hilir Regency continues to occur. The problem analyzed in this research was analyzing the hotspot data, the…
ABSTRACT Water allocation is a way of distributing water to water users by providing a certain amount of water in a service area (water district) so that it can be distributed fairly, evenly and efficiently. The demand for water cannot be avoided, but it must be predicted and planned for the best possible utilization. The tendency that often occurs is an imbalance between the availability and …

This work was carried out on the campu…
ABSTRACT In the hydrology, information about rainfall on a low time scale (per-hour) is very important. Therefore, rainfall measurements are carried out both on a high time scale (daily) and a low time scale (hourly). In this research, rainfall modeling on a low time scale in Pekanbaru City was carried out using the Neyman-Scott Rectangular Pulse (NSRP) stochastic approach. In the NSRP app…
