“…This study is a continuation of previous research based on the briquette quality standard used, namely SNI 01-6235-2000, about the Quality of Wood Briquettes [14]. From previous studies, the results of the characteristics of coal bottom ash (water content, ash content, calorific value) and the elemental composition and morphology were obtained [8].…”

Research has been carried out on the use of coal bottom ash as a material for making briquettes as an alternative fuel. Carbonized of rubber seed shells and Halaban wood were used as mixtures and tapioca flour as adhesives. The composition used in making Halaban wood charcoal and coal bottom ash briquettes is 100%: 0%, 90%: 10%, 80%: 20% and 70%: 30%. Tapioca flour used was as much as 5%, the pressure of 150 kg/cm2 and the size of 250 meshes. While for rubber seed shell and coal bottom ash briquettes, the composition used was with ratio 60%: 40% and 70%: 30%; the pressure used was 100, 150 and 200 kg/cm2 and the size of 50 meshes. Tapioca flour used was as much as 5%. The results of the characterization of rubber seed shell and coal bottom ash briquettes were water content (4.35 - 10.65)%, ash content (12.53 - 17.26)%, and calorific value (3,597.59 - 4,549.88) cal/g. While the characterization results of Halaban wood charcoal and coal bottom ash briquettes were water content (2.947 – 4.097)%, ash content (0.383 – 26.667)%, and calorific value (4,749-6,621) cal/g. The results showed that if coal bottom ash in the composition were higher, it would increase the water content and ash content of the briquettes, while the calorific value would be lower. The recommended composition of coal bottom ash was about 10-20 %. While if the briquettes pressure was higher, the water content, ash content and calorific value would be smaller. The recommended pressure was 150 kg /cm2.

“…This shows that the biobriquettes of banana stems and corncobs in this composition have better combustion quality than the biobriquettes of fish bones and bagasse. [19] reported in their study that the lower the levels of SO2, NOx, and CO emitted from the combustion of bio-briquettes, the better the quality of the briquettes.…”

The increase in fossil fuel consumption has led to the depletion of oil and natural gas reserves, necessitating the development of alternative energy sources from renewable biomass. Agricultural waste such as corn cob and banana stem, which are abundant in quantity, can be utilized as alternative bio-briquette fuel. This study aimed to synthesize bio-briquette using a mixture of corn cob and banana stem and investigate the influence of banana stem and corn cob composition on bio-briquettes’ characteristics. The bio-briquette production process involved pyrolysis at a temperature of 350°C for corn cob and banana stem carbonization. The variations in banana stem composition with corn cob were 10%:90%, 30%:70%, and 50%:50%, respectively. The quality of the bio-briquettes was tested according to the SNI 01-6235-2000 standard. The research results showed that an increase in banana stem composition generally resulted in a decrease in moisture content, volatile matter, and calorific value but an increase in the ash content of the bio-briquettes. All variations of bio-briquette composition met the SNI 01-6235-2000 standard for moisture content, fixed carbon, and calorific value. The highest calorific value was obtained at a composition of 10% banana stem and 90% corn cob, which measured 8929 cal/g. The emission test results for bio-briquettes with a composition of 10% banana stem and 90% corn cob indicated concentrations of SO2, NOx, and CO parameters at 65,67 mg/Nm3, 0 mg/Nm3, and 307,3 mg/Nm3, respectively.

“…Fly ash can be used as a mixed material in the manufacture of lightweight concrete bricks. These bricks have good strength, high thermal insulation, and contribute to energy savings (Haryanti, 2017). Fly ash can be used as a material to form a strong and stable landfill foundation (Aditya, 2019).…”

The cement industry is one of the most important industries in the development of a country. However, the production activities of the cement industry also cause significant environmental impacts, one of which is air pollution. One of the by-products of fuel combustion in the cement industry is fly ash, which if not managed properly can pollute the air and the surrounding environment. This research aims to provide an overview of the environmental impacts of using fly ash in the cement industry, especially in relation to air pollution. This research uses the literature review method, which is by collecting and reviewing literature or documents related to the research topic. The data sources used in this research are scientific journals, books, and other related documents. Data analysis in this study was carried out by reviewing and examining literature or documents related to the research topic, then summarizing and compiling the results of the analysis into an overview. Based on the results of this study, it can be concluded that the use of fly ash in the cement industry has significant environmental impacts, especially related to air pollution. However, there are several technologies and fly ash processing methods that can reduce the environmental impact of cement industry production activities, such as the use of fly ash as raw material for making lightweight concrete or as raw material for the production of other building materials.
