Abstract

One of the greatest contributors of environmental damage in the world are manufacturers. Therefore, an assessment of environmental impacts caused by manufacturers is necessary, and included in ISO 14001: 2015. One of the requirements in ISO 14001: 2015 is Life Cycle Assessment (LCA). PT. X, a large printing company in Jawa Tengah located in a high population district area with a population density of 1,698 people/km 2 (BPS, 2018) in 2015, is concerned about the environmental health surrounds the company, especially for the human health aspect for the employees. In order to maintain the human health aspect in PT. X, an LCA on production process in PT. X is necessary to be conducted to identify which process harm the human health aspect. The LCA in this research conducted according to ISO 14040 LCA steps, including: goal and scope definition; inventory analysis; impact assessment; and interpretation. The goal and scope step in this research decided for the production process in PT. X, with time span of six months in 2019. The inventory analysis step in this research discovered the additional vapor emission outputs of Aminoethylethanolamine in plate printing process, Hexane in printing process, and Isopropanol in varnishing process. The impact assessment step in this research conducted using openLCA software, with GaBi 2018 database and ReCiPe Midpoint method. The interpretation step in this research concluded that the processes with significant environmental impacts regarding human health for production process in PT. X are printing process and varnishing process. To reduce the emission caused from those processes, this research suggested to add dilution ventilation in those processes. This research also suggests PT. X to substitutes the using of: Aminoethylethanolamine compound into turpentine oil; Isopropanol compound into hydrogen peroxide; and silicone liquid into phosphate esters.
