Abstract

Combustion of biomass produces thermal energy that can be utilized of other energy utilities by conversion through fluidized combustion systems. Fluidized reactor with a system (fluidized bed) is an option to the existing conversion thermal energy in biomass. Fuel feed system on combustion chamber (combustor) and fluidized combustion reaction chamber (burner) at fluidization reactor unit integrated with utility boilers producing steam into the reactor performance targets, this is achieved by the provision of fuel to the prescribed amount and timeliness of feeder working system for supplying fuel to the combustion chamber (combustor). Maximum combustion temperature results obtained in between 20 to 30 seconds burning time for 2 (two) kg biomass. Combustion temperature is strongly influenced by the characteristics of biomass. Solid biomass character (wood chips and branches of dry wood planers) has a higher burning temperature of biomass fibers character (areca nut husk). The increase in temperature results for biomass combustion filamentous more quickly reach peak combustion temperature, the comparison is time for biomass burning wood character requires 30 seconds burning time , while for areca nut husk biomass only takes 20 seconds burning time for 2 kg of biomass .

Abstract

Calcium carbide residue is an unutilized by-product. It contains high calcium and can be used to produce cementitious. The variation of Calcium carbide residue used is 0%, 5%, and 15%. This study focused on the reduction of the cement used and lightweight bricks resistance toward the fire condition. Moreover, the tests were carried out by examining the compressive strength before and after lightweight bricks burned, X-ray fluorescence (XRF), Scanning Electron Microscope (SEM), and Fourier-Transform Infrared Spectroscopy (FTIR). The result showed a decrease of compressive strength on 10% and 15% carbide variation. At the combustion temperature of 250 °C, micro-cracking occurred at 0% and 5% carbide specimens, while not only cracking but also spalling and crazing were at the specimens with 10% carbide. The 5% variation of calcium carbide residue can increase the compressive strength and endurance at 250 °C. At the higher temperature, the compressive strength was decreased, and the material was damaged. IR-spectroscopy test results showed that 5% carbide composition achieved the highest compressive strength because the amount of H2O2 used reacts with CaO.

Abstract

Waste glass constitutes significant landfill waste, leading to environmental concerns. Considering its chemical composition, glass powder contains 50% to 60% silica, making it suitable for construction materials. Consequently, this community service initiative introduced waste glass as a building material, serving as a partial substitute for sand in construction products. In addition, the activity involved teaching partners how to create castings/road gates utilizing waste glass. The target partners in this activity were productive business groups engaged in selling wind holes, well rings, rosters, and similar products. The approach applied involved socialization and hands-on practices at the partner's premises. The program's success was obtained through interviews and product compressive strength tests with the partners. The outcomes demonstrate the partners' keen interest in the activity, their understanding of the benefits of utilizing waste glass as a partial sand replacement, and their ability to create products. Notably, the compressive strength of the products created with the partners ranged from 24.72 MPa to 30.84 MPa, aligning with the SNI 03-2442-1991 standard for road curbs (30 MPa). The activity positively impacted the partners, enhancing their business prospects and contributing to environmental sustainability. The training helps in enhancing the partners' skills and capabilities.
