塑料废物在海洋环境中的积累,由于其对陆地的负面影响,增加了海洋污染的全球风险,生态系统,尤其是食物链和海洋生物。无效的塑料废物管理降低了沿海环境的质量,包括社区卫生和健康。景观,和沿海景观,并影响了旅游业等经济部门,渔业,和航运。沿海地区的经济和公共活动一直是塑料废物直接或间接泄漏的来源。各种变量相互关联,一些有影响的变量和其他现有的变量没有有效地工作,并且在系统中不能最佳地相互支持。该政策不限制塑料生产和某些类型的塑料,如包装或一次性使用,袋子,缺乏管理能力导致雅加达湾沿海和海洋目前的塑料废物管理负担。因此,该研究旨在分析影响雅加达湾塑料废物管理的变量的作用和相互关系。通过小组讨论公众参与,采访,并采用Micmac分析方法进行鉴定,地图,分析它们的相互关系,角色,以及塑料废物管理系统中的等级制度。结果表明,变量相互作用的动态影响其绩效和贡献水平。具有强大影响力的变量具有增强他人的潜力,虽然有些人高度依赖废物管理系统,很容易在废物管理系统中表现不佳,因为它们的稳定性依赖于其他变量的表现。一组变量受其他变量的影响很大,表明它们的影响力较低,依赖性较高,而其余变量与系统相对断开。改善废物管理的关键是提高在有影响力和中间象限中发现的变量的性能和关系质量。此外,间接影响变量也需要考虑,因为它们有可能有助于未来的系统战略或情景规划。
The accumulation of plastic waste in the marine environment has increased the global risk of marine pollution due to its negative impact on land, ecosystems, and especially the food chain and marine organisms. Ineffective plastic waste management has reduced the quality of the coastal environment including community sanitation and health, landscapes, and coastal views, and influenced economic sectors such as tourism, fisheries, and shipping. The economic and public activities within coastal areas have consistently as the source of plastic waste leakage either directly or indirectly. Various variables involved and connected each other, some influential and other existing variables were not working effectively and do not support each other optimally in the
system. The policy without limitation on the plastic production and certain type of plastic such as packaging or single-use, bags, and a lack of management capacity have led to the establishment of a burden on current plastic waste management within the coastal and marine of Jakarta Bay. Therefore, the study aims to analyze the roles and interrelation of variables that influence plastic waste management in Jakarta Bay. Public participation through group discussion, interview, and Micmac analysis method was used to identify, map, and analyze their interrelationships, roles, and hierarchy in the plastic waste management
system. The results showed that the dynamics of variables\' interaction affect their level of performance and contribution. The variables with strong influence have the potential to strengthen others, while some had a high dependence which was vulnerable to have ineffective performance in the waste management
system as their stability relied on other variables\' performance. A group of variables were greatly affected by others and indicates that they had lower influence and higher dependence, while the rest of the variables were relatively disconnected from the
system. The key to better waste management is to improve the performance and the quality of relationships of variables that were found in the influential and intermediate quadrants. Furthermore, the indirect influence variables also need to be considered as they have the potential to contribute to the future
system strategy or scenario planning.
