The pulp and paper industry ranks third in water use after the metal and chemical industries. The use of water in the industry impacts the liquid waste produced. The effluent from the pulp and paper industry has a very complex composition. Therefore it is almost impractical to characterise all the components like other industrial wastewater. Based on government regulations, liquid waste di…
This study aims to provide an alternative to intersection handling management based on existing traffic data by projecting the state of the intersection for the short, medium and long term, whether the degree of saturation has crossed the threshold with a degree of saturation equal to 0.8. If the Degree of Saturation (DS) value is less than 0.80, several management alternatives for handlin…

ABSTRACT The operational speed characteristics of vehicles on the roads in the Riau University environment are quite high. This causes the probability of a traffic accident to increase. The traffic safety tool that has been implemented on the Riau University environmental road is the installation of traffic slowing devices in the form of Rumble Strips and Speed Bumps. This study aims to identi…
ABSTRACT Bagan Batu - Simpang Balam section is one of the national roads in Rokan Hilir district that connects two provinces, namely Riau Province and North Sumatra Province. This road has exceeded the planned age and has not received maintenance again. Therefore, the road requires evaluation by analyzing the remaining life that is still there to serve the traffic load after the planned life i…
ABSTACT School safety zone (ZoSS) is the speed limit controller through installation of markings and signs on the street in the school which is to prevent accidents in order to ensure the safety of the school student. School safety zone (ZoSS) has been in Indonesia since 2006. However, there is no evaluation of whether ZoSS is effective enough to improve school safety. The objective of thi…
ABSTRACT The boundary section of Kuansing Regency - Muara Lembu is one of the national roads. The road has exceeded its planned lifespan and there has not been any rehandling. Therefore, the road requires evaluation by analyzing the remaining life that is still available to serve the traffic load after the planned life has expired. This research aims to predict the remaining service life b…
ABSTRACT Utilization of grain as a natural coagulant has been widely used. This is an alternative to the use of synthetic coagulants. Mung bean seeds can be used as a natural coagulant because they contain protein. This study aims to determine the effect of coagulant dosage and slow stirring time on the efficiency of turbidity removal and TDS in river water using natural coagulants from mung be…
ABSTRACT Peat water is surface water that’s found in swampy and lowland areas that contain high organic substances, are acidic and dark brown to blackish in color, which in quality do not meet the criteria for clean water quality. The high content of organic substances and color in peat water is difficult to be treated conventional coagulation-flocculation processes due to lack of turbidity,…
ABSTRACT In terms of quantity, peat water has the potential to become a source of clean water. However, in terms of quality, peat water is not acceptable for utilize because of the high content of organic matter and color. The high organic matter and color of peat water make it difficult to treat peat water with the usual coagulation-flocculation process, so kaolin was added in this research. …
ABSTRACT Sail River is one of the tributaries of the Saik River that crosses Bukit Raya District, Tenayan Raya District, Sail District and Lima Puluh District, Pekanbaru City. The Sail Watershed (DAS) is in a densely populated and activity-dense area. The Sail River also acts as the main drainage in Pekanbaru City, community activities around the Sail River such as residential areas, plantatio…
ABSTRACT Peat water has a high content of organic matter and color, so it is not suitable for direct use for clean water without processing it first. Processing that can be done is the coagulation-flocculation method using natural coagulants. The natural coagulant used is made from corn seeds (Zea mays L.). This study aims to analyze the ability of coagulant corn seeds (Zea mays L.) in the…
ABSTRAK In the operation of an electric power system one of the most important issues is stability. The imbalance between the mechanical input power and the electrical load power in the system causes the generator rotor speed (system frequency) and voltage to deviate from normal conditions so that it will disrupt the stability of the system. In this research a simulation of SMIB without PSS wa…
