Abstract

Bottom ash incinerator produced by PT. X from various waste from production tenant activities has physical characteristics like cement, so it possible to use it as a substitute for cement in paving block mixtures. This utilization aims to determine the effect of using bottom ash on paving blocks according to the compressive strength and water absorption parameter. The composition of cement, and bottom ash in making paving block was varied in this experiment, for amount of sand and water used were same. Drying process for the paving block took 28 days. The bottom ash replace cement by 0 percent, 5 percent, 10 percent and 15 percent respectively, and two replications done for measurement. The quality of paving block was test based on the SNI 03-0619-1996 to determine the level of quality of paving block. The results of this study indicate that the treatment used were significance different based on compressive strength but were not significance different based on water absorption parameter. The substitution of bottom ash in paving blocks based on compressive strength, for treatment C (with 10 percent bottom ash) complied with quality B and treatment D (with 15 percent bottom ash) complied with quality D of paving block standard. Based on water absorption parameter all treatment complied with quality B and D (treatment A, B, and D complied with quality D and treatment C complied with B quality). By considering booth parameter, treatment C (with 10 percent bottom ash) complied with B quality and treatment D (with 15 percent bottom ash) complied with D quality. Other finding from these research showed at least 10 percent bottom ash from incinerator replaced cement used in making paving block.

Abstract

The increase in population certainly greatly affects the amount of existing energy consumption. Based on data taken by the Indonesia Energy Outlook 2019, in 2018 Indonesia has a total final energy consumption (not considering conventional energy) of around 40% of the energy used for the transportation sector, then 36% for industry, 16% for households, commercial and other sectors respectively 6% and 2% respectively. Then, in 2019 the total final energy consumption was 989.9 million Barrels of Oil Equivalent. Then the use of fossil energy has an impact on sustainable life because fossil energy is one of the contributors to carbon emissions on earth. The increase in emissions has an impact on the increase in GHS that has been felt by the earth, namely, the occurrence of very drastic climate changes, as well as affecting temperature rises of up to 3∘C. For this reason, it is necessary to have the potential for renewable energy by utilizing solar energy, namely the process of converting energy produced by solar radiation into electrical energy and efficient use of this energy using smart buildings.. Objectives: The aims of the journal is to know another potential energy sourced to reduce the fossil fuel uses. Method and results: Literature review.
