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).

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 …

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…
ABSTRACT The availability of average rainfall data in Indonesia is not sufficient to be used in hydrological analysis. The disaggregation method is one of the data generation methods to obtain rainfall data covering high time scales and low time scales. Rainfall data generated at lower time scales must match data at higher time scales. In this study, rainfall disaggregation of Dumai City w…
ABSTRACT Indonesia is one of the countries with the largest rubber production and palm oil exports in the world. Large production requires large utilization as well. Lack of utilization of a waste can cause accumulation which has the potential to have a negative impact on the environment. This study aims to determine the benefits of crumb rubber as an additive in an asphalt mixture of AC-WC ty…

The load capacity of old reinforced concrete structures is often insufficient to meet current standards. This is due to increased load requirements, inadequate shear requirements of the original design, material degradation, or increased capacity associated with flexural reinforcement. This study experimentally analyzed the behavior of existing reinforced concrete beams 2000 x 150 x 200 mm …
The oil and gas injection well drilling project is one of the methods used to optimize oil and gas production in old oil fields by utilizing water as an injection medium which will later fill the pores of the reservoir rock and force the remaining petroleum to flow into production wells. In an oil and gas injection well drilling project, there are 3 main stages that must be passed for the …
