The need for methanol in Indonesia continues to increase…
ABSTRACT Along with the development of the era, the need for fuel oil is increasing. The development of research and the use of diesel motors in industry will not stop just because of the depletion of fossil fuels. The search for alternative fuels as a substitute for diesel continues to be carried out in addition to dealing with the problems of the global energy and environmental crisis as wel…
ABSTRACT Acrolein (2-propenal / C3H4O / CH2 = CHCHO)) is the simplest unsaturated aldehyde compound. The main characteristic of acrolein is its high reactivity due to the conjugation of the carbonyl group with the vinyl group. The uses of acrolein include protecting liquid fuels from microorganisms, making the essential amino acid methionine and as a good separator and dispersing agent, widely…
ABSTRACT There are more motorized vehicles in Indonesia in line with the increasing demand for fuel. This development will have a negative impact, environmental pollution so MTBE is a substances with a lower risk and environmentally friendly are chosen. The target market of this factory is to meet the need for MTBE in Indonesia and to export it to the Asia Pacific region. MTBE production …
ABSTRACT Acrolein (C3H4O) is the simplest unsaturated aldehyde compound but is highly toxic and high reactivity due to the conjugation of a carbonyl group with a vinyl group. The uses of acrolein is protecting liquid fuels from microorganisms, making essential amino acid methionine and as a good separator and dispersing agent which is widely used in the ceramic, paper and electroplating indust…
ABSTRACT The need for ammonia increases along with the number of finished products that use ammonia as a raw material in the manufacturing process. Ammonia is widely used in the fertilizer industry, textile industry and as a refrigerant. The main raw materials used in manufacture of ammonia by the KBR (Kellogg Braun and Root) process are natural gas and air. This plant is planned to operate fo…
ABSTRACT The need for phenol and acetone in Indonesia is increasing every year. Based on data from the Central Bureau of Statistics, in the last 5 years, the amount of phenol imports was 20,000 - 26,000 tons/year and the amount of acetone imports was 17,000-22,000 tons/year. Phenol is used as raw material for caprolactam industry, raw material for bisphenol-A which is used in the manufacture o…
ABSTRACT The presence of Water the peat found in Riau and the water potential used as a source of drinking water. Peat water containing high organic so it needs processing before use. The content of organic substances and the high color in peat water hard to set aside with the process of coagulation – flocculation process, so in this study added peat mud. This study aims to determine the…
ABSTRACT The adsorption process of artificial Cu 2+ solutions was investigated using an adsorbent made from Empty Fruit Bunches . TKS is one of the largest solid wastes produced from agricultural activities which contain lignocellulose. This research aims to study the effect of KOH variations and contact time of activation on iodine number, methylene blue and surface area of the TKS and to stu…
ABSTRACT Forest and land fires can produce Greenhouse Gas (GHG), most of which are in the form of carbon dioxide (CO2) which are harmful to health and the environment. The purpose of this study was to determine the distribution of hotspots in Riau Province as forest and land fires, estimate forest and land fires, and calculate carbon dioxide (CO2) emissions from burned areas on different l…
The supply of clean water in Riau Province can only reach urban areas, thus encouraging some people in rural areas to use peat water to meet their needs. Peat water does not meet the specified clean water quality standards because it has the characteristics of a brownish red color, low acidity and high organic matter content. This study aims to treat peat water using a ceramic membrane filtrati…
ABSTRACT The country of Indonesia is ranked second in the world for producing plastic waste, so the use of plastic waste must be carried out. The use of plastic waste as an additive in asphalt mixtures can improve the quality of asphalt concrete pavement and also reduce plastic waste. This study aims to determine the effect of adding plastic waste to the characteristics of modified asphalt…
ABSTRACT Rotating Alga Biofilm Reactor (RABR) is a biological wastewater treatment using microorganisms with suspension and biofilm culture processes. The microorganism used in this study was the microalgae Chlorella sp. that require nutrients such as carbon, nitrogen and light for growth. This nutrient source is obtained from domestic wastewater which has a high organic matter content. In thi…
Changes in land cover are the most important factors causing global environmental change. This land cover change causes an increase in gases, especially CO2 gas in the atmosphere, thus becoming one of the causes of carbon gas emissions. The study site is located in Pekanbaru City which is the capital city of Riau Province with a relatively rapid rate of regional development because it is a …
ABSTRACT The adsorption process of artificial Cu 2+ solutions was investigated using an adsorbent made from Oil Palm Empty Fruit Bunches (EFB). EFB is one of the largest solid wastes produced from agricultural activities which contain lignocellulose. The characterization used for physical activation and physical-chemical activation adsorbents is a FT-IR spectrophotometer. FT-IR analysis showed…
ABSTRACT Domestic wastewater consists of black water and grey water, grey water as the largest contributor to the total domestic wastewater contains organic material.
