Abstract

From the concept of the epidemiological triangle, air pollution is a risk factor that becomes a carrier of disease agents and affects the vulnerability of the human body, including COVID-19. This study aims to see the correlation between PM10, CO, O3, SO2, and NO2 with daily cases of COVID-19 in Padang City. This study uses an ecological study using one year data (March 26, 2020 - March 26, 2021). Data for specific pollutants were obtained from reanalysis datasets of the European Center for Medium-Range Weather Forecast (ECMWF). Meanwhile, data on the COVID-19 pandemic was obtained from the daily report of the Padang City. Spearman and Pearson correlation tests were used to assess the correlation of specific pollutants with COVID-19 daily cases. The results found that CO, O3, SO2, and NO2 correlated negatively with COVID-19 daily cases at lag 0, lag –7, lag –14, and lag –21. In contrast, PM10 positively correlates at lag 0 and lag -7. Social distancing also had a significant relationship with the concentrations of O3 and PM10. Understanding the contribution of air pollutants to the increase of COVID-19 daily cases is essential for preventing more serious health impacts and requiring policy to control the emissions.

Abstract

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).

Abstract

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.

Abstract

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.

Abstract

Abstract: 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.

Abstract

This research study on leakage and flashover currents in silicone rubber treated with coal dust (fly ash) pollutants with variations in the duration of impurity conditioning within 1, 2, 3 days, and no conditioning. This research prepares for testing the RTV 497 silicone rubber test sample which is formed into a sheet with a thickness of 1 mm while the length and width are 50 x 25 mm which is attached with a leaf-like sample electrode system which is designed using the sketch up application with the number of samples of each 5 pieces each for each variation of conditioning carried out, then tested using an Aluminum Tape electrode system with a gap between the Aluminum Tape electrodes of 5 mm. To determine the value of the leakage current that passes through the surface of the Silicone Rubber, voltages of 220 V, 500 V, and 1000 V are applied, left for 1 minute for each voltage application variation to read the value of the current flowing on the sample surface, then the voltage is increased slowly until flashover occurs. The test results showed a leakage current value of 1, 2, and 3 days without conditioning when applying a voltage of 220 V is 34.53; 34.69; 34.81; and 35.09 mA, the same for application at a voltage of 500; and 1000 V that is the leakage current value increases. This is for any current flowing from the conductor to the ground to pass through the outer surface of the insulator. If the surface of the insulator has a layer of contaminants, it can affect the leakage current that flows on the surface. Meanwhile, the flashover test results with the same sample obtained a value of 4112.8; 3819.4; 3676.4; and 3511 V, the data obtained is that the voltage decreases with the longer the conditioning time is carried out since dust contaminants tend to settle and stick to the insulator, which is one of the biggest causes of flashover and failure.
