Abstract

ABSTRACTThe use of disposable diapers contributes significantly to environmental issues. One approach to address this issue is to compost. The Takakura method offers a potential solution, although feces in diapers raises concerns about pathogen contamination. This study aimed to evaluate the safety and quality of compost produced from organic waste and disposable diapers using the Takakura method, focusing on fecal coli levels. Organic waste is a mixture of vegetable and fish waste in different proportions. The two treatments tested were 75% organic waste (vegetable/fish) + 25% diapers and 25% organic waste + 75% diapers, observed on days 10 and 20. On day 20, the 75% fish waste + 25% diaper mixture produced the lowest fecal colony level (33 MPN/g), meeting the Indonesian National Standard (SNI) No. 19-7030-2004. The decrease in fecal coli levels was due to microbial interactions, including lactic acid bacteria and Bacillus from fish waste, which have antimicrobial properties. This study shows that composting disposable diapers with the Takakura method and organic waste can produce compost that meets the standard, especially with 75% organic waste composition. However, due to potential pathogen risks, it is more suitable for non-food crops. Keywords: composting, disposable diapers, MPN fecal coli, organic waste, Takakura

Abstract

Due to the rapid growth of motorized vehicles, Surabaya City faces significant challenges related to traffic congestion and greenhouse gas (GHG) emissions. This growth harms air quality and worsens climate change. Therefore, finding practical solutions to reduce GHG emissions in the transportation sector is important. One potential solution is the implementation of an Intelligent Transport System (ITS), which can improve traffic management and transportation efficiency. This study aims to evaluate the effectiveness of ITS implementation in reducing GHG emissions in Surabaya City. The research methods used include primary data collection through interviews and questionnaires and secondary data obtained from official reports and the implemented ITS system. The analysis was carried out by considering three main aspects: technical, environmental, and institutional, using the CLIMACT Prio method to determine the priority of appropriate mitigation actions. The study's results indicate that implementing an Intelligent Transport System (ITS) in Surabaya City can reduce greenhouse gas (GHG) emissions through several main approaches. ITS optimizes traffic management by reducing congestion and idle time, reducing emissions. In addition, ITS increases the use of public transportation and supports the integration of environmentally friendly vehicles, such as electric vehicles, which reduce dependence on fossil fuels.
