ABSTRACK The combustion process of coal as a fuel in the PLTU XYZ in the form of fly ash, constituting 85%, and bottom ash, accounting for 15%. 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…
Background and Objectives: The 2015 forest and land fires were considered the largest fires in history, so the Indonesian government finally introduced various policies related to peat ecosystems. Forest and land fires have become an annual problem and routine in Riau, which has had an impact on the people of Riau and has also spread to neighboring countries. The purpose of this study is to pro…
This research was carried out from January 2022 to December 2023, at PT Tunggal Mitra Plantation, Manggala 3 Palm Oil Plantation, Rokan Hilir Regency, Riau Province. The research was divided into two stages, where the first stage was a field experiment that ran for two years which aimed to determine the effect of ameliorant application on the chemical and biological properties of peat soil as w…
This research aims to analyze the existing social and economic conditions of the community around the Sosa River, water quality analyzing and the water quality status determining of the Sosa River in Padang Lawas Regency, determine the potential load of Sosa River water pollution in Padang Lawas Regency and determine the sustainability status as well as develop appropriate sustainability strate…
Siak Regency is one of rice production center in Riau Province. However, the threat of drought due to climate change and variability can not be avoided. This study aims to analyze the vulnerability of agricultural drought in Siak Regency in 2023 and formulate mitigation strategies by utilizing climate information. The research employs qualitative approaches, utilizing data obtained through clim…
Peatlands are ecosystems highly susceptible to environmental changes and human activities such as burning, drainage, and land conversion. These actions can degrade the physical, chemical, and biological quality of peat, reduce productivity, increase greenhouse gas emissions, and harm farmers' economies. Sustainable management is crucial to maintaining a balance between ecological, economic, and…
