This study aims to evaluate and ascertain the level of carbon emissions for the construction of a case residential building using life cycle analysis. In an attempt to determine carbon emissions at different stages, the following areas were considered: materials consumed during formwork construction, materials for structure, transportation of materials from factory to site, energy consumed by tenants, carbon emission removals, and disposal of debris. Emission factors were obtained from local sources to have cognitive and representative results. The results therefore established that the total carbon emission throughout the life cycle of the case building is 1,212 tons of CO<sub>2</sub>e&nbsp; which was found to pose a minor threat to the environment according to standard. It was also deduced that carbon emission due to the energy consumed by tenants emerged the most significant with 47% followed by materials for structure (36%), materials consumed during formwork construction (8%), materials based on demolition (7%) while transportation of materials from factory to site and debris to disposal site emerged as the least significant with just 1% each. </em><em>Overall, findings suggest that a sufficient reduction of carbon emissions in building construction starts from the extraction, processing and manufacturing of building materials. Hence, lawmakers and professionals in the built industry should enforce implementable policies that will encourage </em><em>designs of low carbon and sustainable residential edifice.</em></p> Adekunle A Osagie Ibhadode A.P Ibhadode Shawon Msughter Caesar Copyright (c) 2020 Adekunle A, Osagie Ibhadode, A.P Ibhadode , Shawon Msughter Caesar https://creativecommons.org/licenses/by-nc-nd/4.0 2020-08-05 2020-08-05 6 8 1 11 10.31695/IJERAT.2020.3628 The Lean Manufacturing Design For Improving Production Scheduling Using Product Wheel Method in Chemical Manufacturing Company, Indonesia https://ijerat.com/index.php/ijerat/article/view/448 <p>The current production scheduling policy at PT XYZ raises several problems, including the long production lead time for each product, unbalanced inventory between products, and the unavailability of goods requested by customers. Therefore, this research will focus on designing production scheduling improvements at PT XYZ in order to be able to overcome current problems. The product wheel method was chosen to be a proposal to improve production scheduling at PT. XYZ Based on the calculation of Economic Production Quantity (EPQ), the product wheel's production schedule is made into three cycles in which every cycle runs for two days. Cycle 1 produces Tonsil C 1000 by 200 tons, Tonsil B 1000 150 tons, Tonsil A 1000, and Tonsil B Cylo as much as 50 tons each. Cycle 2 produces Tonsil C 1000 for 200 tons, Tonsil B 1000 150 tons, Tonsil A 1000 100 tons, and Tonsil B Cylo for 50 tons. Cycle 3 produces 200 tons of Tonsil C 1000, Tonsil B 1000, Tonsil A 1000, Tonsil B Cylo, Tonsil C 25, and Tonsil B 25, each with 50 tons. Because Tonsil C 25 and Tonsil B 25 are MTO products, they do not always have to be produced when cycle three spins. By scheduling production using the product wheel, we get a more dynamic production schedule than the production scheduling at PT. The previous XYZ was due to product wheel scheduling, the quantity produced, and the production sequence was made based on customer demand so that it was expected that production could run effectively and efficiently.</p> <p> </p> Muhammad Kholil Jakfat haekal Dian Eko Adi Prasetio Sulaiman Hasan Copyright (c) 2020 Muhammad Kholil, Jakfat haekal, Dian Eko Adi Prasetio, Sulaiman Hasan https://creativecommons.org/licenses/by-nc-nd/4.0 2020-08-08 2020-08-08 6 8 12 18 10.31695/IJERAT.2020.3623
