Roadside Environmental Quality Estimations for Particulate Matter 10 (PM10) in Akure-South LGA, Ondo State, Nigeria
Odesanya Joseph Femi Federal University of Technology, Akure, Ondo State, NigeriaTransportation 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.Pages: 1-10Views: - Downloads: -Diversity of Soil Insects in Coal Post Mining Land of PT. Bukit Asam Tbk in Tanjung Enim
Karinda Dwi Paserena Universitas Sriwijaya Indonesia , Nurhayati Damiri Universitas Sriwijaya Indonesia , Dwi Setyawan Universitas Sriwijaya IndonesiaCoal 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.Pages: 11-17Views: - Downloads: -Noise level assessment of Mobile Telecommunication Base Stations Proximate to Residential areas in Accra, Ghana
Francis Kwaku Nkansah University of Education, Winneba Ghana , Worlanyo Kwabena Agbosu University of Education, Winneba Ghana , Kekeli Adanu Ghana , Maxwell Kwame Boakye GhanaThe 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.

Ayu Wulandari Faculty of Mathematics and Natural Science, Sriwijaya University Indonesia , Hilda Zulkifli Universitas Sriwijaya Indonesia , Doni Setiawan Universitas Sriwijaya Indonesia , Agung Laksana Universitas Sriwijaya IndonesiaAbstract: PT Sumatera Prima Fibreboard (PT SPF) is a private company that produces medium-density fibreboard (MDF). PT SPF made a green area in several locations in the factory environment as an effort to reduce air pollution, especially CO2 gas due to MDF production activities. The function of green area as a carbon pool has an important role in reducing and suppressing the release of CO2 emissions into the air. This research aims to determine the value of biomass and stored carbon reserves in saplings, poles, and trees rates, as well as understorey, and litter in PT SPF's green areas. 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.Pages: 24-32Views: - Downloads: -Potential Local Ingredients from Purple Sweet Potato For Weaning Food Using Ultrasound Modified Process

Bambang Dwi Setiyawan Magister Ennvironment Management, Sriwijaya University , Poedji Loekitowati Hariani Universitas Sriwijaya Indonesia , Leily Nurul Komariah Universitas Sriwijaya IndonesiaPT Bukit Asam Tbk has adopted the use of plant-based diesel oil in compliance with the rules established by the Minister of Energy and Mineral Resources No. 12 of 2015 from previously using fossil diesel. One of the decarbonization program's initiatives to reduce emissions is to replace the use of fossil fuels with biodiesel for all production equipment. To obtain results on the decrease or increase in the environmental quality of the use of fossil fuels and biodiesel, this research requires comparative data obtained from the results of ambient air quality, emissions, and opacity test. Based on research data in the years 2018 – 2022, the emission quality test was obtained with an average CO parameter of 550.83 mg/nm3, which exceeded the quality standard of 540 mg/nm3, SO2 parameter of 79.03 mg/nm3 from the quality standard of 900 mg/nm3. The NO2 parameter is 161.29b mg/nm3 from the quality standard of 1200 mg/nm3, with the quality standard parameters referring to thw Minister of Environment and Forestry Regulation No. 15 of 2019. Based on quantitative analysis approaches method and trend analysis obtained the emission results experienced an increase with trend line analysis but were still below the quality standards. The results at IUP Banko Barat for mobile equipment sources were obtained at 5.23% HSU, while for static equipment sources, they were obtained at 9.88% HSU from the quality standard of 40% based on South Sumatera Governor Regulation No. 06 of 2016. It can be concluded that the variance of fuel use for the 2018-2022 period has no significant effect on the air quality test emissions and opacity results because it is still below the quality standard.Pages: 44-53Views: - Downloads: -Existence of Phytoplankton in Waters Affected by Hot Water of Electric Steam Power Plant (ESPP) of Teluk Sirih as Ecological Bioindicator Reference for Climate Change Mitigation
