As a significant contributor of plastic waste to the marine environment, Indonesia is striving to construct a national strategy for reducing plastic debris. Hence, the primary aim of this study is to create a model for plastic waste quantity originating from the mainland, accumulated in estuaries. This was achieved by compiling baseline data of marine plastic disposal from the mainland via comprehensive contextualisation of data generated by remote sensing technology and spatial analysis. The parameters used in this study cover plastic waste generation, land cover, population distribution, and human activity identification. These parameters were then used to generate the plastic waste disposal index; that is, the distribution of waste from the mainland, flowing through the river, and ultimately accumulating in the estuary. The plastic waste distribution is calculated based on the weighting method and overlap analysis between land and coastal areas. The results indicate that 0.6% of Indonesia, including metropolitan cities, account for the highest generation of plastic waste. Indicating of plastic releases to the ocean applied by of developing three different scenarios with the highest estimation 11.94 tonnes on a daily basis in an urban area, intended as the baseline study for setting priority zone for plastic waste management.

使用综合遥感、统计和社会人口数据的印度尼西亚塑料废物积累潜力的多情景模型

作为塑料垃圾对海洋环境的重要贡献者,印度尼西亚正在努力制定减少塑料垃圾的国家战略。因此,本研究的主要目的是为源自大陆、在河口积累的塑料垃圾数量建立模型。这是通过对遥感技术和空间分析产生的数据进行全面背景化,汇编来自大陆的海洋塑料处理基线数据来实现的。本研究中使用的参数涵盖塑料废物产生、土地覆盖、人口分布和人类活动识别。然后将这些参数用于生成塑料废物处理指数;也就是来自大陆的废物分布,流经河流,最终在河口堆积。塑料垃圾分布是基于加权方法和陆地和沿海地区之间的重叠分析计算的。结果表明,包括大都市在内的印度尼西亚 0.6% 的塑料垃圾产生量最高。通过开发三种不同的情景来指示向海洋的塑料释放,最高估计为城市地区每天 11.94 吨,旨在作为确定塑料废物管理优先区域的基线研究。
