Abstract

Usually, the main source of water is a river, which makes it essential to ensure that the water from that source is not polluted and in accordance with the water quality standards. Water quality can deteriorate as a result of domestic and industrial waste. This quality is measured based on several parameters, such as the concentration of pH, nitrate, phosphate, and fecal coliform in the water. QUAL2KW can be used to analyze river water quality in order to solve several water quality-related problems. The main river water source in Semarang Regency is the Klampok River, whose water is used to support agriculture, livestock, and other activities. This study aims to determine the concentration of the above-mentioned parameters in the samples from the Klampok River using QUAL2KW. The water samples are obtained from different six points on the Klampok River, and the chi-square test is used for validation. From the laboratory test results for the river-quality parameters, after being simulated using QUAL2KW and validated using the chi-square method, it can be concluded that the quality of the Klampok River belongs to class II. These results can be used as a reference by the Semarang Regency government in managing river water quality.

Abstract

The environmental awareness of consumer has been growing along with the increase of knowledge, education and access to information. The demand from the government, media, and community has also increasingly escalated the pressure to companies to produce environmentally friendly products. This eventually encourages greenwashing practices extensively which are unfavorable to consumers because the practice is frequently included as marketing scam. In addition, the existing environmentally-based certification is primarily oriented to the planet and profit aspects of the triple bottom lines and tends to ignore the community. Hence, this study reviews a variety of green-based certifications or sustainability indicators which has existed particularly in Indonesia and their potential for the development of convenience products, products which are consumed in high frequency since they are cheap and consumed daily. This research involves explorative analysis using open secondary data from public journalism, media releases, academic references, and official webpages. Furthermore, this research describes current green-based certifications and presents the initial concept of a sustainability indicator which involved the planet and humans concurrently as well as adopt Proper label as product labelling.
