https://ejournal.arcomteknologi.id/index.php/ICISTSD <p>Environmental issues are very important and take attention to most countries in the world. Regional planning and development considering environmental sustainability are mandatory in recent years. In other words, the development of an area should be considered a sustainable environment. Innovation in sciences and technologies is compulsory in all disciplines including regional planning and development. A collaboration between various fields of knowledge is needed to tackle the sustainable development issue, such as environmental problems, sustainable regional planning, and management. The development of research and technology addressing those issues is very progressive. Also, it potentially improves to build a cross-field<br>collaboration between the institutions at the international level.&nbsp;</p> Universitas Mahasaraswati Press en-US Proceeding 1st International Conference of Innovation on Science and Technology for Sustainable development (ICISTSD) 2020 https://ejournal.arcomteknologi.id/index.php/ICISTSD/article/view/1459 <p>The waste bank is one of the formal sectors in the effort to reduce waste in the city of Surabaya. East Surabaya has 100 active waste banks, but there are 32 inactive waste banks. Plastic waste management in East Surabaya cannot be separated from the role of the formal and informal sectors. The waste bank activities support the waste recycling process and circular<br>economy in the city of Surabaya. Plastic waste recycling activities can reduce waste but still have an impact on the environment. The purpose of this research is to analyze the environmental impact associated with recycling plastic waste through waste banks. The data collection method in this research is through surveys to waste banks, BSI, small scrap dealers, Large-scale<br>enterprises, and recycling industries. The results of direct interviews can determine the process, generation, residue, and distribution of recycled waste. The process carried out, and the resulting residue was analyzed using the IPCC and journals to determine the resulting environmental impact. The results showed that plastic recycling through waste banks causes emissions to<br>the environment. A total of 17.18 tonnes of plastic (0.11% of the total plastic waste in East Surabaya) resulted in GHG emissions of 74.19-74.34 tonnes of CO2e.</p> Dwi Wulandari IDAA Warmadewanthi Ellina S Pandebesie Mokhamad Nur Cahyadi Maria Anityasari Ni Made Utami Dwipayanti I Gede Herry Purnama Amar Addinsyah Copyright (c) 2020 Proceeding 1st International Conference of Innovation on Science and Technology for Sustainable development (ICISTSD) 2020 2020-12-30 2020-12-30 1 1 https://ejournal.arcomteknologi.id/index.php/ICISTSD/article/view/1766 <p>Methyl orange dyes are often used in industrial activities and produce wastewater that can pollute the environment. One of the plants that usually live in water and usually used phytoremediation is pistia plan. This study aimed to determine the acute toxicity (LC-50) of pistia plants in methyl orange wastewater. This study consisted of two stages, acclimatization and range-finding tests. The reactor used in the study has volume 5 L. The detention time in determining acute toxicity for pistia plants is 30 days. The acclimatization stage for seven days showed a profitable growth in the pistia plant. The LC-50 value in pistia plants showed a value of 58.73 mg/L. Knowing the LC-50 value in pistia plants is<br>used as a standard reference for wastewater treatment containing methyl<br>orange into the waters. The lethal concentration (LC-50), which can kill<br>50% of the pistia plant, is 58.73 mg/L.</p> Anshah Silmi Afifah Darwin Darwint Muhammad Rizki Apritama I Wayan Koko Suryawan Copyright (c) 2021 Proceeding 1st International Conference of Innovation on Science and Technology for Sustainable development (ICISTSD) 2020 2021-03-21 2021-03-21 1 1
