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 …
