Daily river flow data from 1971 to 2017 was used for the assessment. Generalized extreme value distribution was applied in order to estimate exceedance probabilities associated with historical observation data at different return periods. Environmental water allocations of the river at different ecological conditions were estimated using the intra-annual and inter-annual flows. This study has estimated the hydrological yearly conditions (very dry, dry, average and wet) for the river basin. Moreover, the method has also successfully proposed the environmental water allocations to achieve the desired ecological conditions, which are very good ecological (Eflow class A), good ecological (Eflow class B), medium ecological (Eflow class C), and deficient ecological conditions (Eflow class D). In general, the proposed method has been capable and acceptable for the assessment of Eflow of Johor river basin in line with sustainable water management goal.</p> 2022-08-31T00:00:00+00:00 Copyright (c) 2022 Noor Hisham Ab Ghani, Zulkifli Yusop, Mohd Zaki Mat Amin, Thian Siaw Yin https://journal2.unusa.ac.id/index.php/ETM/article/view/3410 Potential of rainwater harvesting in wilayah persekutuan Malaysia 2022-08-26T03:04:37+00:00 Anisa Ratnasari aratnasari72@gmail.com Arya Bhaskara Adiprabowo aratnasari72@gmail.com Andhika Gilang Al Afgani anisaratnasari72@gmail.com Atik Widiyanti anisaratnasari72@gmail.com Lily Oktavia anisaratnasari72@gmail.com <p>Although Malaysia has abundant water resources, some parts of Malaysia are currently facing water shortage problems. The increasing demand for water has sparked initiatives to seek alternative water supplies. Rainwater harvesting has been proposed by governments as part of the solution to alleviate the problem of water scarcity. Literature related to rainwater harvesting is available from a variety of sources. In this study, rainfall was analysed as a crucial factor affecting RWHS efficiency, rainwater potential at different zones for residential, industrial, and commercial. In addition, the study evaluated the rainwater quality that obtain fresh rainfall and roof rainfall. Furthermore, potential of treatment technology for rainwater was suggested to optimate rainwater harvesting.</p> 2022-08-31T00:00:00+00:00 Copyright (c) 2022 Anisa Ratnasari, Arya Bhaskara Adiprabowo, Andhika Gilang Al Afgani, Atik Widiyanti, Lily Oktavia https://journal2.unusa.ac.id/index.php/ETM/article/view/3335 Concept of green marketing in environment conservation: A Literature review 2022-08-24T20:20:58+00:00 Peter Onyonje Osiako peterosiako78@gmail.com Edza Aria Wikurendra edzaaria@unusa.ac.id Nour Salah Abdeljawad noor.salahabdaljwad@ammancity.gov.jo <p>The concept of green marketing mix is as well as the conventional marketing mix refers to the satisfaction of customer needs, wants, and desires related to the maintenance and preservation of the environment. Consumers interest in environmental care creates opportunities for companies to apply green marketing and to increase sales. Green marketing becomes an alternative strategy helps the company's image, adds value to the company's business, even consumers demand green choices and will to pay higher prices. The marketing strategy includes the company's external and internal factors. The marketing mix strategy is the basic idea and generic function of marketing which consists of product, price, place, and promotion elements to shape the occurrence of sales. Developing the concept of green marketing mix (green marketing mix) is inseparable from the traditional 4P concepts (product, price, place, promotion), except a number of additional component are closely related to the intent of green marketing itself and other very influential things. The implementation of a green marketing strategy requires a fundamental, comprehensive and integrated approach in all functional aspects of marketing, including the overall marketing mix, such as product design, pricing, location and promotion.</p> 2022-09-01T00:00:00+00:00 Copyright (c) 2022 Edza Aria Wikurendra, Peter Onyonje Osiako, Nour Salah Abdeljawad https://journal2.unusa.ac.id/index.php/ETM/article/view/3408 Groundwater quality assesment in Ropar wetland between summer season and winter season 2022-08-26T03:09:54+00:00 Goh Zhu hang gohzhuhang@gmail.com Nelda Maelissa gohzhuhang@gmail.com Loh Zhang Zhan gohzhuhang@gmail.com Atik Widiyanti gohzhuhang@gmail.com Winda Umarie gohzhuhang@gmail.com Eddy Setiadi Soedjono gohzhuhang@gmail.com <p>Water covers 70% of the world’s total surface, but only around 3% of it is freshwater that humans may drink and utilize for other purposes. Because of fast growth in many nations, the quality of groundwater is no longer adequate for human consumption. The objective of the study is to assess the groundwater quality of 18 locations in the Ropar wetland in Punjab, India, in different seasons and different source groundwater. When compared to uncontaminated natural groundwater, the groundwater obtained from the test sites had higher pH values. The amount of groundwater pollution is higher in the summer than in the winter. However, there are many challenges face by the groundwater quality research. The groundwater quality in any region of the world is very important towards the survival of human being. Long-term consumption of polluted groundwater with high levels of heavy metals will result in health issues such as difficulty breathing and renal failure.</p> 2022-09-06T00:00:00+00:00 Copyright (c) 2022 Goh Zhu hang, Nelda Maelissa, Loh Zhang Zhan, Atik Widiyanti, Winda Umarie, Eddy Setiadi Soedjono https://journal2.unusa.ac.id/index.php/ETM/article/view/3406 Green technology of natural fiber reinforced bio-composites as alternative sustainable product 2022-08-26T03:01:35+00:00 Tony Hadibarata tonyhadibarata8@gmail.com Winda Umarie windaumari@gmail.com Bieby Voijant Tangahu bieby@gmail.com Putri Ramadhany putri@gmail.com Gilang Ananda Putra gilang@gmail.com <p>Proactive strategies are being opted by metallurgical, foundry and manufacturing industries with respect to their experiences working with product designing based on product life cycle assessments. Without the consideration of the potential impacts on the life cycle, the development of new products would barely be sustainable. “Green” composites or bio-composites are fully degradable composites mainly consisting of a blend of biopolymer matrix and natural fibers which act as a reinforcing phase. In this study, natural bio-composite was reviewed as an alternative sustainable product. The types of natural fibers were also described as raw material of natural bio-composite. In addition, development natural fibers nowadays were mentioned. Furthermore, the application of natural fiber reinforced bio-composites was also presented.</p> 2022-09-23T00:00:00+00:00 Copyright (c) 2022 Tony Hadibarata, Winda Umarie, Bieby Voijant Tangahu, Putri Ramadhany, Gilang Ananda Putra
