ABSTRACT Food waste is the highest component of solid waste generated in Indonesia, and improper management contributes significantly to greenhouse gas emissions. One major source of food waste is the food service sector, including the canteens of the Faculty of Engineering (FT) and the Faculty of Economics and Business (FEB) at the University of Riau. This study aims to analyze food waste gen…
ABSTRACT Activities of street vendors in the Riau Main Stadium Area, Pekanbaru City, generate various types of waste, notably biomass waste comprising sugarcane bagasse and corn cobs. The generation rate of this biomass waste reaches 117.2 kg/day of sugarcane bagasse and 12.5 kg/day of corn cobs. The carbon content within this biomass waste can be utilized as renewable energy in the form o…
ABSTRACT The rising quantity of automobiles has resulted in a heightened need for engine lubricating oil, which has an impact on the increasing amount of used oil waste. Used oil is classified as B3 waste that has the potential to pollute the environment if not managed properly. One way to manage it is by refining used oil into an alternative diesel fuel. This is because used oil still con…
ABSTRACT Used car oil will cause various problems if it is not managed properly. This is because used oils contain a variety of hazardous components such as heavy metals and carcinogenic substances. This study aims to look for optimal conditions for refining used engine oil into alternative fuels, specifically focusing on combining the Acid and Clay methods with distillation. The methodolo…
Background and Objectives: Forests function as a habitat for living things and are a supporter of oxygen availability throughout the world. Forests also function as absorbers of 25% of carbon dioxide emissions that are released into the atmosphere due to human activities, and Indonesia is the country with the third largest forest area in the world. Forest fires are a routine problem in Indonesi…
Industrial growth and increasing economic demands in the energy sector, particularly in petroleum and natural gas, have significantly contributed to the acceleration of environmental degradation. Exploration and production activities in the oil and gas industry generate various types of waste, one of which is oil sludge. Improper management of oil sludge can lead to ecological, economic, and so…
Riau Province, which has a large area of forest and land, is one of the contributors to the recurrent forest and land fires that occur every year. One of the most severe districts is Indragiri Hulu Regency. Statistically, in the past year there were 91 forest fire disasters with a burned area of 578 hectares. The increase in the incidence of forest and land fires in Indragiri Hulu must be contr…
ABSTRACT Medical waste incineration in hospitals may release microplastic particles into the atmosphere. Microplastics are plastic particles ranging from 1 μm to 5 mm in size, characterized by their light weight, ease of dispersion, and potential risks to human health and the environment. This study aimed to analyze the abundance, types, and polymer composition of airborne microplastics a…
ABSTRACT Siak River water has a high natural organic matter (NOM) content, which has the potential to form disinfection by-products in the form of trihalomethanes (THM) when it reacts with chlorine. THM are carcinogenic and have fatal impact on human health, so treatment is necessary before disinfection. This study aims to calculate the efficiency of organic and color removal in Siak R…
ABSTRACT The Siak River, a source of raw water for Pekanbaru City Water Company, contains organic matter content and high water color. Organic matter content in river water will produce THM when disinfected with chlorine, so it is necessary to treat organic matter before disinfection. This study aims to calculate the efficiency of organic matter and color removal and determine the optimal…
ABSTRACT Sago bark has potential as an alternative raw material for environmentally friendly bioenergy, with the potential bio-pellets from sago bark capable of producing a calorific value of around 4,855 kcal/kg, thus meeting the biomass pellet standard for energy. This study aims to analyze the effect of co-firing variation of sago bark biomass pellets based on SNI 8951:2020, to assess t…
