Roadside Environmental Quality Estimations for Particulate Matter 10 (PM10) in Akure-South LGA, Ondo State, Nigeria

Transportation serves as a vibrant sector for current civilization without which commerce, industrialization and societal development will be slowed or impossible, however, movement in space is not without its negative outcome, part of which is the generations of particulate. Objective of this research is to analyses Particulate Matter 10 (PM10) on roadside in Akure-south LGA of Ondo State, Nigeria. Traffic movement were collected along these corridors with the aid of counting and then disaggregating them into various categories such as passenger cars, heavy trucks, motorcycles and buses, while, CLJ-D Particulate counter (100-1million (PCS) Brand) was used in collecting PM10 particles generated along the traffic corridor. Finding show that the highest PM10 generated along the corridor is 1019 µg/m3 and the least generated PM10 is 312 µg/m3, while the corridor with the highest traffic is with 3973 pcu/hr and the lest has 1299 pcu/hr traffic volume. The research concluded that although the traffic volume is not exclusively the only contributor to PM10, in the selected corridor, there could also be some other contributors as the areas generating highest traffic movement do not mean highest PM10

Noise level assessment of Mobile Telecommunication Base Stations Proximate to Residential areas in Accra, Ghana

The installation of base stations in Accra and other urban centers meant to expand mobile phone network coverage has met opposition from the public. This study was carried out to assess the noise levels of generators utilized at the mobile telecommunication base stations focusing on noise levels from mobile telecommunication base stations in residential zonings only at the night (2200-0600). The methodology for data collection involved a quantitative approach using simple compliance coefficient data analysis. The study results showed that noise levels from generator sets at base stations in residential areas were not always below the Environmental Protection Agency’s (EPA) threshold of 48dB within the hours of 2200 to 0600 at a distance of 50m from base stations. There is, therefore, noise pollution in this perimeter which has been classified as a residential area with negligible or infrequent transportation. In this regard, district assemblies ought to strictly implement a minimum setback distance of not less than 50m of telecommunication BSs from the closest residential structure

The relationship of community livelihoods in and around forest reserve areas to forest resources in Humbanghasundutan District of North Sumatra Province

Forest resource management needs to pay attention to the relationship between the community and forest resources.  The conversion of forest land into non-forest areas affects the livelihoods of communities around the forest itself; therefore, knowledge of the socio-economic and cultural interrelatedness of communities in and around forest areas is needed so that the sustainability of forest resources and community livelihoods is maintained.  This study was an explorative one. The data were obtained based on questionnaires and interviews. The respondents were selected purposely considering the characteristics of the research area.  The data analysis was presented using descriptive method. The observed factors were in the form of land history, land tenure and livelihoods originating from the forest area.  This study showed that the historical and customary norms were related to the conversion of forest land to other land uses. The interrelatedness of the community and the forest area was the provision of forest products, namely rubber latex, incense resin, cinnamon bark, firewood, bananas, durian, salak (Salacca Zalacca L.), jengkol (Archidendron pauciflorum L.) and petai (Parkia speciosa L.).  Most of the people were not aware of the existence of forest areas legally designated by the government.   Consequently, although most respondents did not know the existence of the forest areas legally, they were closely related to forest areas in the form of intensive use of forest products. The history and customary norms prevailing in the community were factors related to the conversion of forest land functions

This research used stratified purposive sampling methods. The saplings, poles, and trees biomass used non-destructive method by recording the species, and the diameter at breast height. Understorey and litter biomass measurements used destructive method by taking parts of the understorey and litter above the surface as samples. Based on this research, there were 13 saplings, poles, and trees rates species belonging to 9 families and 13 understory species belonging to 11 families in the research plots. The potential for saplings, poles, trees, understorey, and litter carbon storage in 5 green areas of PT SPF with total area of 16,673 m2 (1.67 ha) is 471,20 tons and classified as a good category

Diversiry of Soil Insects in Coal Post Mining Land PT. Bukit Asam Tbk in Tanjung Enim

Coal mining activities carried out openly can have a negative impact on the environment. One of the environmental damages that occurs is the loss of habitat for soil-level insects. This research was conducted to identify the diversity of soil surface insect species in post-coal mining land of PT. Bukit Asam Tbk Tanjung Enim IUP Banko Barat at various ages of reclamation. Soil surface insect samples were collected using the pitfall trap method which was carried out for 1x24 hours. The results showed that the highest presence of soil surface insect species occurred in aged 6 years with a total of 128 individuals and was dominated by the order Hymenoptera. The species diversity index in post-coal mining land aged 6 years, namely 1.51, is classified as moderate. The lowest presence of soil surface insects occurred in aged 2 years with a total of 24 individuals. The species diversity index in post-coal mining land aged 2 years, namely 0.85, is relatively low. Thus, the research results show that the diversity of surface soil insects is influenced by the age of reclamation. The longer the land is managed, the higher the index of diversity of soil surface insect species in post-coal mining land

Reusing Coal Waste as a Blending Material for Hollow Block Production to Boost Circular Economic of FABA

In the world and Indonesia, coal is one of the primary fuel sources for steam power plants (PLTU). This is due to the shrinking and increasing prices of fuel oil. With the abundance of coal energy sources, it continues to be used as the primary energy source for power plants in Indonesia. The economic efficiency obtained can reach 80% compared to the use of solar. However, Fly ash and Bottom ash (FABA), or solid waste produced from the coal combustion process at the PLTU, contains many inorganic minerals, which can pollute the environment, such as air and soil pollution. Conventionally, regarding economic law, Construction and Demolition (C and D) in the circulation system between materials and products must have zero material value and no longer produce residual waste in final disposal. This research implements Circular Economy (CE) to minimize the negative impact of FABA on the environment at PLTU. The experiment used FABA Coal as a mixed material to make Hollow Blocks with six combinations of sizes. The results obtained, the greater the percentage of FABA used, can minimize production costs and improve the quality of hollow blocks. From an economic cost analysis, using FABA for mixed materials for open block production will provide 55% greater economic benefits and 34.67% higher quality Hollow blocks compared to the composition of materials without FABA mixture

Recovery of Burned Peatland: Revegetation Pattern Planning in Palm Oil Concession, South Sumatra

Peatland ecosystems can recover from fire disasters through ecological succession, revegetation or both. In the context of oil palm plantations, revegetation planning for peatlands aims to restore the hydrological and carbon storage functions of peatlands, as well as to continuously increase the diversity of local vegetation by minimizing engineering activities on the land. This study explores the factors that influence revegetation of peatlands, identifies the distribution of water table levels as the main determinant. The water table levels, which vary from approximately 10 cm to 110 cm, correlate with topographic conditions and significantly impact vegetation survivability. The dominant plant species in the study area is Purun (Eleociharis dulcis), occupying approximately 44.5% of the total area. Other adaptable vegetation types, such as Gelam (Melaleiuca spp.) and Perepat (Combretocarpus rotundiatus), are considered suitable for propagation and planting as part of the peatland revegetation program. The study recommends prioritizing revegetation in areas with low vegetation diversity. Planting in areas with deep groundwater levels (60-80 cm) is recommended during the dry or humid months (June to September), while planting in areas with shallow groundwater levels (0-40 cm) is better conducted in the rainy season (October to December)
