ABSTRACT The use of steam time and temperature during the preheating and prehydrolysis stages, as well as heating in the cooking process, has a significant impact on the final quality of dissolving pulp (AE). These two parameters result in P-Factors and H-Factors, which are important indicators in determining the quality of dissolving pulp (AE). Understanding the effect of P-Factor and H-F…
ABSTRACT The sedimentation rate in a slurry is the speed at which solid particles settle out of the liquid due to the force of gravity. A dispersant is a dispersing agent used to ensure that the particles in the GCC slurry remain stable, do not clump together, and do not settle. This study aims to determine the effect of dispersant dosage on the sedimentation rate, viscosity, and solid con…
ABSTRACT The manufacturing process of Ground Calcium Carbonate (GCC) involves wet grinding which requires a certain energy known as Specific Grinding Energy (SGE). This energy is critical in achieving the desired particle size and has a direct impact on the quality of the final product as well as the efficiency of the energy used in the process. This study aims to analyze the effect of pow…
ABSTRACT The DA stage is an important stage in the process of increasing brightness because the DA stage is a delignification stage to damage and separate the remaining lignin structure in the pulp. This study aims to determine the effect of temperature and time on brightness, fiber morphology and tensile strength. In this study, the DA bleaching process was carried out using chlorine dioxide …
ABSTRACT Mangrove forests typically grow along coastlines and play a crucial role in protecting coastal areas from sea water-induced abrasion. Rangsang Island is located in a coastal region directly facing the Malacca Strait, making it vulnerable to coastal abrasion and shoreline changes. Google Earth Engine (GEE) is a platform that facilitates research related to shoreline changes caused …
ABSTRACT This study aims to evaluate the reliability of the SPI-3 (Standardized Precipitation Index) generated by Google Earth Engine (GEE) by comparing it with manual calculations using Microsoft Excel, as well as to analyze the correlation between SPI-3 and hotspot occurrences. SPI-3 monitoring is conducted due to the high fire susceptibility of peatlands during drought conditions, highl…
This study investigates the effectiveness of combining the Snyder Synthetic Unit Hydrograph (SUH) with three flood hydrograph models—Alexeyev, Gama I, and Nakayasu—in estimating High Direct Runoff (HDRO) across six sub-watersheds located in the southern region of the Siak River Basin, Pekanbaru City, Indonesia. The methodology integrates watershed characterization using Geographic Info…
ABSTRACT Unpredictable earthquakes have a major impact on structures, especially without bracing which has low strength against seismic forces. This study aims to analyze the effect of bracing on the natural frequency and dynamic response of SDOF and MDOF structures using the time history method. The dimensions of the structural system modeling refer to data from previous laboratory studie…
ABSTRACT The University of Riau campus area frequently experiences inundation during the rainy season, highlighting the need for effective and sustainable flood mitigation strategies.
