Environmental pollution generally occurs because of the behavior of workers who are not environmentally friendly. The purpose of this research is to analyze the relationship of environmental awareness to the behavior of workers of palm cooking oil company; examine the relationship of implementation of ISO 14001 environmental management system to the behavior of workers; analyzing the relationship of implementation of ISO 14001 environmental management system and environmental awareness simultaneously to the act of workers. The results were processed by univariate, bivariate, and multivariate methods. The results of the analysis show a weak and unidirectional relationship between environmental awareness and employee behavior with correlation value (R=0.23). Different results on the ISO 14001 environmental management system with worker behavior. The results show no relationship between the ISO 14001 environmental management system and workers’ behavior with correlation values (R=0.39). While the correlation between environmental awareness and ISO 14001 environmental management system to worker behavior showed a strong correlation with correlation value (R=0.56). The conclusion that can be drawn from the results of the analysis is the awareness of the environment plays an essential role in the behavior of workers in the eenvironment. Corporate programs such as the ISO 14001 environmental management system can not run effectively without the support of environmental awareness.
Introduction: Environmental management systems (EMS) were used commonly by companies to control industrial impacts and support environmental sustainability. In achieving SDG’s indicators to focuses on improving sustainable practices in the company environment, the government faces a tough challenge in increasing ISO 14001 certified companies. This study aimed to analyze the barriers and benefits of ISO 14001 certification in the industrial sector and recommend encouraging companies to carry out ISO 14001 certification. Methods: This study used a descriptive analysis method to identify the perception of ISO 14001 certified company practitioners of the certification barriers and benefits. Through survey questionnaires, data collection was conducted to 83 ISO14001 certified companies with a response rate of 49.4%. Results and Discussion: The main barrier in performing the ISO 14001 was the cost of implementation and certification. The highest benefit of ISO 14001 certification was to improve the company's image. A total of 83% of the companies believed that the benefits of ISO 14001 certification outweighed the costs incurred. Conclusion: The companies did not have significant barriers in conducting the ISO 14001 certification and classified into the medium category. The ISO 14001 certification could provide environmental sustainability, social, market, and economic benefits. The government needs to support the interest of companies in conducting the ISO 14001 implementation by overcoming the obstacles and maximizing the benefits.
This paper presents the Life Cycle Assessment (LCA) of a 640 MW combined cycle power plant located in West Java, Indonesia. The power plant adopts the dual-fuel firing system, in which both natural gas and high-speed diesel fuels are used. The LCA was performed using the open-source LCA software OpenLCA version 1.9. A functional unit of 1 kWh of electricity generation was used in calculating the environmental impacts. The system boundary was modeled using the gate-to-gate system, which includes all inputs and outputs for the following subsystems: fuel storage, water preparation, electricity production, and supporting subsystems. The life cycle inventory (LCI) used data gathered from July 2018 to June 2019. The CML-IA baseline method was used to perform the life cycle impact assessment (LCIA), providing results for ten midpoint impact categories. All impact categories were normalized using World 2000 normalization factors. The result shows that the most significant impact categories are acidification potential (AP), eutrophication potential (EP), and global warming potential (GWP), respectively. The largest acidification source is nitrogen oxide emission from the combustion chamber, with a percentage of 80.32%. Regarding the combustion stage, the post-combustion method is recommended to remove nitrogen oxide from exhaust gases to lower the AP impact category.
Dumai City, located in Riau Province is the second largest city in Indonesia and is also currently facing problems with solid waste management as the population continues to grow. Dumai Timur District is the most populated district in Dumai City with 68.980 people. The Municipal Solid Waste (MSW) in Dumai Timur District- particularly the plastic waste, paper, and metal; is expected to have some economic potential if seen from the Circular Economy (CE) perspective. Therefore, this study is conducted to quantify and characterize the MSW generated in Dumai Timur District and to analyze the economic potential of inorganic solid waste. The number of solid waste sample was determined by SNI-19-3964-1994 method and carried out using simple random sampling. The results showed that the estimated total household waste generated in Dumai Timur District is 7.772.735,76 kg/year or approximately 0,31 kg/person/day waste generated on average. The three largest waste composition consisted of organic waste, plastic and paper that represents 68,02%; 12,26%; and 8,08 respectively. The economic potential value was estimated up to Rp 871.605.708,42.5.
Managing the environment is vital in guaranteeing beneficial effects to environmental action for oil and gas companies. This study aimed to analyze the programs and efforts to prevent environmental pollution by applying the Environmental Management System (EMS) in the oil and gas industry. The most popular, frequently applied EMS is the ISO 14001 and Amdal. This study used a literature review method from 26 literature and three databases: Google Scholar, ScienceDirect, and Scopus. Inclusion criteria in this study are articles related to the environmental management system in Indonesia’s oil and gas company. This study looked forward to giving insights to the actors in this industry in using the opportunity to invest while implementing efforts to prevent environmental damages and their impacts. Six underlying parts of the choice cycle have been created and utilized in using EMS: strategy/arranging, project appraisal, execution, technical thoroughness, interview, and institutional trustworthiness.
