Reusing Coal Waste as a Blending Material for Hollow Block Production to Boost Circular Economic of FABA
Syaiful Syaiful Universitas Sriwijaya Indonesia , Dinar Dwi Anugerah Putranto Universitas Sriwijaya Indonesia , Irwin Bizzy Universitas Sriwijaya IndonesiaIn 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.

Putri Nilam Sari Faculty of Public Health, Andalas UniversityFrom 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.

Taufik Taufik Balai Pemantapan Kawasan Hutan Wilayah II Palembang Indonesia , Sulistyowati Diah Kusumawardhani Balai Pemantapan Kawasan Hutan Wilayah I MedanForest 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.

Nazula Nutayla Environmental Management Program, Graduate School, Universitas Sriwijaya, Palembang 30139, South Sumatera, Indonesia Indonesia , Amin Rejo Agricultural Engineering Department, Faculty of Agriculture, Universitas Sriwijaya, Ogan Ilir 30662, South Sumatra, Indonesia Indonesia , Rizky Tirta Adhiguna Agricultural Engineering Department, Faculty of Agriculture, Universitas Sriwijaya, Ogan Ilir 30662, South Sumatra, Indonesia IndonesiaThe majority of coal mining is done using open pit mining techniques, which have an effect and present a challenge to changes in the chemical, physical, and biological characteristics of the soil. Restoration of ecosystems damaged by mining activities is prioritized through revegetation of reclaimed land. The purpose of this study is to evaluate how well Angsana plants develop faster in coal mining reclamation zones when they are planted directly. Field data and observations are utilized to assess the growth of plants that are directly planted in land reclaimed after mining activities. The growth parameters that are observed involve counting the number of leaves for plants using both seedlings and stem-cutting planting materials. The results showed that the average leaf growth in seedling planting material treated with bokashi fertilizer exhibited normal growth with more leaf characteristics compared to the control treatment. However, during the period of 2 to 4 weeks after planting, abscission occurred in leaf growth. The growth in the number of leaves on the seedling planting material was observed from 6 weeks after planting until the end of the study. Meanwhile, the average leaf growth on the planting material of cuttings occurred from 4 weeks after planting to 12 weeks after planting. However, slow leaf growth was noted in the planting material of cuttings treated with coal fertilizer at a dose of 1 kg/planting hole, where leaf growth occurred 11 weeks after planting.

Supriyadi Supriyadi Environmental Management Study Program, Sriwijaya University Indonesia , Satria Jaya Priatna Soil Science Department, Agricultural Faculty, Sriwijaya University Indonesia , Muhammad Bambang Prayitno Soil Science Department, Agricultural Faculty, Sriwijaya University Indonesia , Muhammad Umar Harun Agronomy Department, Agricultural Faculty, Sriwijaya University Indonesia , Mokhamad Yusup Nur Khakim Physics Department, Mathematics and Natural Science Faculty, Sriwijaya University Indonesia , Risfidian Mohadi Chemistry Department, Mathematics and Natural Science Faculty, Sriwijaya UniversityPeatland 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).Pages: 165-171Views: - Downloads: -Identifying the Implementation of Three Attributes of Green City in Gorontalo City
Zamaludin Mantali School of Architecture, Planning and Policy Development, Institut Teknologi Bandung IndonesiaOver time, population growth in Gorontalo City will continue to increase. While the condition of land for housing will not increase. This is certainly one of the problems that requires seriousness in handling it. Based on data from the Central Bureau of Statistics of Gorontalo Province in 2012 to 2021, population growth in Gorontalo City continues to increase from 189,476 people to 199,788 people. This causes a decrease in the quality of the environment in Gorontalo City which results in the emergence of slum areas and climate change, in this case global warming. As an effort to overcome these problems, Gorontalo City is currently implementing the Green City concept. Green City is an environmentally friendly and sustainable city development concept. In this research, the author uses Qualitative Research Method by identifying the distribution of three Green City attributes to find out how important the improvement of the three attributes is in the Green City concept in Gorontalo City. The three attributes that the author refers to include Green Open Space, Green waste, and Green Community. The output of this research is an increase in the principles of Green City attributes from each element of the Green City attributes so as to create a Sustainable and Environmentally Friendly Gorontalo City Regional Development supported by the city community itself.
