To mitigate environmental pollution, bottom ash presents potential as an alternative material to partially replace fine aggregates, such as sand, in the production of concrete, bricks, and paving blocks. This study aims to analyze the compressive stren…
ABSTRACT Palm oil mill effluent (POME) contains high COD levels ranging from 38,080 to 44,928 mg/L. The appropriate method for treating wastewater with high COD concentrations is anaerobic treatment, one of which is using an upflow anaerobic sludge blanket (UASB) reactor. This reactor is effective in wastewater treatment and capable of producing biogas. This study aims to investigate the effec…
ABSTRACT Teluk Kenidai Village is located in Riau Province and is characterized by peatland. The local community utilizes this peatland primarily for agricultural activities. A common method the residents employs to convert peatland for agricultural use is through burning. This practice leads to the degradation of the peatland, which in turn results in the release of stored CO2 into the atmosp…
ABSTRACT Peat water has characteristics such as a dark color (reddish brown), high organic content, high iron content, and high acidity. Palm Oil Fly Ash (POFA) is waste from the boiler combustion process by the factory. POFA has a silica content that has the potential to be a basic material for making geopolymers. Utilization of POFA as a low-cost adsorbent is one solution in waste management…
ABSTRACT Palm Oil Fly Ash (POFA) is a solid waste from palm oil that has a high silica and alumina content. This shows that POFA can be used as a raw material for making geopolymers. Geopolymers are polymers made from non-organic natural materials. Geopolymers have the potential to be used as adsorbents in both powder and spheres form. This study aims to analyze the effect of the SiO2/Na2O and…
ABSTRACT Tenayan Raya Steam Power Plant (PLTU) uses coal as the main fuel to produce dust emissions containing heavy metals. Observations around the PLTU in the Office Area to see the impact of dust fall dispersion are estimated to come from the PLTU which contributes cadmium (Cd) metal content and transportation activities that contribute lead (Pb) metal content. This study aims to analyze the…
ABSTRACT Oil palm empty fruit bunches (EFB) are the largest waste from the management of fresh fruit bunches (FFB). Only 70% of the total EFB waste is utilised, while the rest becomes waste and damages the environment. The lignocellulose content in EFB is very high, which is 28% for cellulose, making it suitable for activated carbon as an adsorbent. This study was conducted, to determine and a…
ABSTRACK The Steam Power Plant (PLTU) industry that uses coal has the potential to be a source of air pollution that is detrimental to health and the environment. The aim of this research is to determine the magnitude of the risk characteristics due to exposure to manganese (Mn) and lead (Pb) metals in dustfall in residential areas around the Tenayan PLTU using the Environmental Health Risk An…
Peat water contains natural organic matter (NOM) dominated by humic substances. This organic content causes several problems in water bodies, such as color and odor. Besides organic matter, peat water also contains inorganic substances such as dissolved metals, namely iron (Fe). The iron (Fe) content in peat water also causes the water to turn brown and can cause health problems, so it needs to…
ABSTRACT Waste generated from household activities has various types such as organic, inorganic and waste containing Hazardous and Toxic Materials (B3). The type of household waste that contains B3 is often referred to as Household B3 Waste (SB3-RT). SB3-RT has characteristics that pose a risk to human health and the environment, so this waste is classified as specific waste that requires spec…
ABSTRACT Large-scale waste production is triggered by increasing industrial activity and infrastructure development, the waste produced on a large scale is bottom ash and silica fume. Bottom ash and silica fume are wastes that have not been optimally utilized. Paving block is one of the paving constructions that are widely found in the community, but the development of road infrastructure trig…
Carbon Monoxide (CO) and Lead (Pb) are gases commonly produced through incomplete combustion of motor vehicles. This research aims to analyze the environmental health risks due to exposure to Carbon Monoxide (CO) and Lead (Pb) gases from vehicles along the front road of Pasar Pagi Arengka, Pekanbaru City. Data was collected for 6 days with measurements taken for 1 hour in the morning and aftern…
Bunga Raya District is an area predominantly characterized by peatland, where the groundwater quality is reddish-brown, has a taste, odor, and high iron content. This makes it unsuitable for daily drinking water needs. Besides the poor groundwater quality, the Bunga Raya District is not fully serviced by the government’s drinking water supply system. Therefore, an alternative solution is need…
Siak Kecil district has the conditions of an area that is dominated by sludge, so the water quality is very inadequate in quantitative and qualitative terms. Meanwhile, the region's only source of water relies on rainwater. Because of the soil conditions in this region, which have a high level of acidity and hairs, the groundwater becomes a very rough and brown colour containing organic compoun…
Hydrogen sulfide (H2S) and ammonia (NH3) are hazardous gases commonly found in waste management facilities. This study aims to analyzethe environmental health risks associated with H2S and NH3 emissions from the Solid Waste Management Facility of Arengka Morning Market in Pekanbaru City. Data collection included waste characteristics, meteorological conditions, and H2S and NH3 concentrations. T…
Production machine activities in the steam generator unit at PT.XYZ, generate noise with noise levels at the boiler machine (98.4 dBA), softener machine (87.1 dBA), and storage tank (85.6 dBA). The value obtained exceeds the threshold value (NAB) of 85 dBA so that it can cause disturbances to workers, one of which is fatigue. The study aims to determine the noise level in the Steam Generator un…
Pusako District is a sub-district located in Siak Regency with land and peat water areas, with relatively high Pb, Cd and Cu content. Therefore, the community cannot use groundwater for drinking water needs.
