“…For SBE and palm fiber, there is still an opportunity to be used as AF by carrying out additional processing. Solutions that can be taken include blending with other fuels that have high calorific value, ensuring optimal drying conditions, [27,28] and briquetting for biomass waste [29]. With this approach, solid waste can be treated and utilized efficiently as AF in the cement manufacturing process, so that it can still provide positive economic and environmental benefit [30].…”

To reduce fossil fuel usage and promote eco-friendly energy, PT Semen Padang uses Alternative Fuels (AF) instead of coal. This study focuses on projecting the use of solid waste as AF from 2023-2030. It compares the waste's calorific value and proximate analysis with standards, calculates its potential use based on the Thermal Substitution Rate (TSR), and plans the necessary equipment. The tested waste includes Spent Bleaching Earth (SBE), rice husk, calliandra, palm fiber, and sawdust. The AF's characterization follows ASTM D 2015 for calorific value and ASTM 3172-3175 for proximate analysis. Results are compared to the RDF Specification Guidelines of 2017. The largest volume of waste used as AF is SBE (35,060 tons/year), while the smallest is 397 tons/year in stage III (2029-2030). Rice husk, calliandra, and sawdust meet the standards for AF in cement production. SBE doesn't meet the calorific value and ash content standard, and palm fiber doesn't meet the moisture content standard. The potential use of solid waste as AF reaches PT Semen Padang's target of 5.792% from 2023-2027. The necessary equipment for waste utilization as AF includes a shredder, dryer, mixing machine, and pyrolysis reactor.

“…Consequently, research has been undertaken to establish the distance at which the flame comes into contact and the elevation of the gas burner as means of maintaining a consistent burning distance [10]. Nonetheless, these findings have indicated that shorter burner distances lead to the production of exhaust gases and inefficient combustion, while higher burners compromise stove efficiency due to increased flame-object distance [11].…”

Experimental investigations were conducted to assess the impact of an adjuster on the heating efficiency and flame stability of sago waste briquettes. The adjuster was introduced to maintain a consistent burning distance, thereby enhancing the combustion heat of the fuel. Infrared thermometry was employed to monitor the temperature evolution within the briquette and the combustion load, represented by water in a pan. The findings demonstrate that adding an effective adjuster significantly improves the performance of both the briquettes and the stove, resulting in enhanced effectiveness and efficiency. This is evident from the observed increase in combustion temperature and faster boiling time of the water. The consistent burning distance ensures a stable and uniform heat supply to the briquettes, facilitating more efficient fuel utilization as all parts of the fuel can undergo complete combustion and transfer heat to the pan. Molecular analysis reveals that the stability of the burning distance weakens the Van der Waals bonds within the carbon chain, thereby increasing the reactivity of the fuel molecules. Consequently, the fuel exhibits improved heat absorption capability and becomes highly combustible.
