Primary CO2 emissions and secondary CO2 emissions from household activities are still very limited. Therefore, there is no data that shows how much CO2 emissions are generated specifically by household activities in Simpang Baru Village, Binawidya Subdistrict, Pekanbaru City, so an analysis is carried out. The purpose of this research is to calculate and determine the amount of CO2 emissions fr…
Microplastics are pollutant materials originating from plastic in the various shapes and sizes with a diameter 1 μm - 5 mm. microplastics have the potential to become pollutants that have a negative impact on aquatic biota because they are abundant in the aquatic environment. This study aims to analyze the abundance, types, and polimer types of microplastics in water and fish in the Sago River…
POME has a high chemical oxygen demand (COD) content of 33,600 mg/L. The presence of POME in the environment is a potential pollutant due to the high COD content which makes POME difficult to decompose. The appropriate processing method to reduce the COD content in POME is anaerobic processing using an upflow anaerobic sludge blanket (UASB) reactor with the concept of Two-Stage UASB for hig…
Mining activities have made a major contribution to various aspects of life throughout the world. In the biophysical aspect, mining activities can cause direct changes in land cover. Apart from areas that are directly affected by environmental damage due to oil mining, there are several other areas that have an indirect impact on mining activities. One of them is the borrow pit area, which is a…
Continuing to increase the number of industries in Kampar Regency has a positive impact on the community's economy, but can have a negative impact on the environment if the quality of the waste water produced by these industries is not monitored before being discharged into water bodies. This research uses a type of qualitative descriptive research which is intended to obtain information regar…
Industrial progress has caused environmental issues such as the generation of liquid waste. Liquid waste from industries contains various harmful chemical compounds that are sparingly soluble, such as lead from pulp and paper industries and copper from electroplating industries. The objective of this research is to determine the optimal adsorbate concentration and temperature for the adsorption…
Spent mushroom substrate (SMS) is an organic compost medium produced from mushroom cultivation processes. Biological processing has attracted attention due to its substrate specifications and larger reactions, lower energy requirements, reduced pollution, and higher desired product yields. Processing TKS waste requires large areas of land and generates pollution, so it needs to be converted int…
Spent mushroom substrate (SMS) is a biomass waste produced from mushroom production which leaves mushroom residue in the planting medium, which contains negatively charged groups such as hydroxyl, carboxyl acids and phenolic groups which can bind heavy metals. The aim of this research is to obtain the optimum temperature and adsorbate concentration in the biosorption of heavy metals Pb(II) and …
Spent Mushroom Substrate (SMS) is an organic material that has been pasteurized and is produced from biomass after mushroom harvesting, which has the potential to act as a biosorbent. The mushroom Coprinus comatus, a lignin-degrading fungus, can be utilized as a biosorbent. Composite material refers to the combination of these two substances to enhance metal absorption efficiency. The objective…
Narcotics abuse is one of the problems facing the Indonesian nation today. Narcotics abuse not only has an impact on the user, but also has an impact on weakening national resilience. This condition is even more worrying because the target market for these narcotics dealers is mainly teenagers aged 12 to 21, and more than half of the prisons in Indonesia are currently convicts for drug cases. C…
Tembilahan City has a landfill with an Open Dumping management method which causes several problems including the capacity of landfill, no waste sorting process, ineffective operational waste facilities and infrastructure. The impacts caused are negative impacts such as leachate pollution, air pollution, and impacts on health. The positive impact, especially for scavengers, if managed well, is …
Peat water has a high Fe content. One of processing method to remove Fe levels in peat water is the aeration method using a cascade aerator. Aeration is the process of adding oxygen to water so that it can cause an Fe oxidation reaction which will form Fe(OH)3 precipitates. This research aims to analyze the ability of a zeolite cascade aerator to reduce Fe levels in peat water using variations …
PT Pertamina Gas Operation Rokan Area is oil and gas companies that operates in the petroleum distribution network in the Rokan Working Area. The greater the company's operations, the greater the chance of environmental pollution due to petroleum spills. Environmental pollution that often occurs is pollution of the soil that causes petroleum-contaminated soil (PCS). An alternative solution in p…
Electroplating industry wastewater contains various heavy metals, one of which is hexavalent chromium metal (Cr VI). The high content of Cr (VI) metal ions in wastewater will have an impact on humans such as skin infections and can damage environmental ecosystems. A widely used method to remove Cr(VI) metal ions in wastewater is adsorption. Adsorption is the process of adsorbing a substance on …
Disposal of waste containing heavy metals such as cadmium Cd (II) and chromium Cr (VI) in high concentrations into water bodies can pollute the environment and interfere with human health. One method that can be used to reduce heavy metal levels is the adsorption method using adsorbents as absorbent materials. Hollow carbon fibre acacia is one of the adsorbents that can be used as an adsorbent …
Palm Oil Mill Effluent (POME) contains high chemical oxygen demand (COD) of 33.600 mg/L. POME contains high concentrations of organic matter and if not treated can be damage to the environment. The most suitable treatment is anaerobic treatment using an upflow anaerobic sludge blanket (UASB) reactor. The purpose of this research is to study the effect of hydraulic retention time (HRT) variation…
Livestock development is an important aspect of agricultural development, especially during the economic and monetary crisis. The role of the livestock sub-sector in agricultural development is quite significant, one of which is the poultry industry, where the poultry industry is the main trigger for business development in the livestock sub-sector. Apart from its role in taking advantage of em…
The vast potential of marine in the region offers opportunities for theft and illegal exploitation of marine resources by individuals and groups that harm the country and the community, such as illegal fishing, piracy, smuggling, human trafficking, piracy, and illegal migration.
