ABSTRACT Palm oil mills in addition to producing crude palm oil also produces by-products in the form of Palm Oil Mill Effluent (POME). POME contains high amounts of organic ingredients and pollutants. One method that can be applied to process POME is High Rate Algae Reactor (HRAR) System. The HRAR system utilizes consortium of indigenous microalgae-bacterial that has better performance in r…
ABSTRACT Green Open Space (GOS) is one of the efforts to deal with increasing GRK emissions because it has the ability to absorb CO2 emissions. Pekanbaru Development Area IV is one of the Development Areas that has the potential to produce carbon dioxide (CO2) emissions. This research was conducted to determine the amount of motorized vehicles and the value of CO2 emissions produced each day…
ABSTRACT Peat water in quantitative subject is very potential to be proceed for cleaned water in water resources. But in qualitative aspect, there is so much problem, there are the colour (dark brown), low PH, and high organic inside. The using of Biocoagulan is the best way as alternative for decrease the using of sintetic coagulant that can influence our health for a long term use. The purpo…
ABSTRACT Transportation is the most influential source in increasing levels of carbon monoxide (CO) in the air. Pekanbaru is the capital of Riau province which is experiencing rapid economic development that is a cause of population growth and increasing the number of motorized vehicles. The purpose of this study is to measure CO concentrations from mobile sources then compare them with PP N…
ABSTRACT Palm Oil Mill Effluent (POME) is wastewater that has high organic matter content. The treatment process of Palm Oil Mill Effluent (POME) generally with the open pond system can be one of the contributors of greenhouse gases in the form of CO2 and CH4 gases. To prevent the release of greenhouse gases, microalgae are used by using POME which contains organic ingredients as a nutritio…
ABSTRACT One of the decreases in environmental quality is caused by pollution of carbon dioxide (CO2) from transportation activities. Pasir Pengaraian City is one of the cities that has potential as a producer of carbon dioxide (CO2) emissions from transportation activities in Riau Province. One effort to reduce the concentration of CO2 in urban air is by applying the concept of green area o…
Research on the design, fabrication of magnetic susceptibility equipment based on Quincke method have been carried out. The design of the the equipment was drawed using Corel Draw X7 software. The fabrication of the equipment solid iron plate material, axles solid iron, copper, connections, and U meniscus pipes. The magnetic induction of the solenoid of 3000 turns, length 10 cm and diameter 10 …
ABSTRAK The increase in vehicle ownership causes transportation activities to increaase. The tendency to increase the number of motorized vehicles operating, will add to the burden of traffic one example is the increase in noise intensity. This study aims to map the pattern of noise distribution and to determine the level of noise that occurs in Jenderal Sudirman street Pekanbaru city by takin…
The effect of ball size of milling on magnetic properties and composition of Arta Sand Beach Pariaman has been studied. The sand beach was processed utilizing the iron sand separator to obtain the concentrate I. Concentrate I was milled by Ball Milling method using various ball sizes such as 0,3, 0,5, 0,8, and 1,5 cm. Separation of magnetic and non-magnetic particles resulting from Ball Milling…
