“…The amount of marine litter estimated by our study was lower than that reported by Cordova et al (2022). However, their mean abundance of the stranded debris, ranging from 1.83 to 4.33 items/ m 2 , aligns relatively towel with our study.…”

“…These plastic sachets are used to package items such as snacks, shampoo, lotion, and seasoning, known for being relatively affordable and cheaper than other forms of packaging. The three-year research of Cordova et al (2022) and the findings of our study suggest that the composition of litter in marine environment has been constant over the years, reflecting the similar economic lifestyle of Semarang City citizens over the time. The hypothesis of this study assumed that litter accumulation originates from inland-based activities and waste transported by rivers from the surrounding area (Lauer and Nowlin 2022).…”

“…In Bali, the most famous tourist spot in the world, around 0.08 to 1.69 items/m 2 with a weight ranging from 0.25 to 17.94 grams/m 2 of marine debris has accumulated in the coastal ranges (Suteja et al 2021). Cordova et al (2022) found that during the sampling periods of 2018-2019, the density of plastic debris stranded along Indonesian beaches ranged from 1.31 to 2.69 -items/m 2 , with an average weight of 166.09 ± 75.55 grams/m 2 . In comparison to other marine litters, plastic waste accounts for the highest proportion of the total litter (46 -86.9%) and is found in many coastal areas of Indonesia (Renjaan et al 2020).…”

Indonesia is one of the largest contributors to global marine litter deposition, given its high population and the largest archipelagic country. The increasing problem of plastic littering has recently attracted the attention of researchers. This study aims to identify marine and macroplastic litter in Semarang City. A field survey was conducted by dividing the beach into 18 sampling grids, each with an area of 1 × 1 m2. A literature survey was also conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology to identify literature that can be used to develop recommendations. The results showed that 6.26-11.16 grams/m2/ day of marine litter and approximately 1.61-4.89 items/m2/day of plastic litter would be deposited on Semarang City beaches. The greatest contributors to macroplastic litter were polypropylene (PP) and low-density polyethylene (LDPE), which should be considered for further intervention. Strategic recommendations were developed based on an in-depth literature survey and best practices in the current field. These also include recommendations that can be used as a reference by policymakers and other stakeholders to reduce marine pollution. The results of this study are expected to provide a multiplier effect on reducing marine pollution for the city.

“…It is believed that these fragments originate from degraded large plastic items. Throughout coastal areas of Indonesia, there is a significant amount of single-use plastic litter, including shopping bags, sachets, food containers, wrappers, bottles, and cups (Cordova et al, 2022a). Over time, due to natural weathering and physical stressors like biological deterioration or environmental factors, larger plastic waste breaks down into smaller pieces (Fok et al, 2017;He et al, 2019;Nurhasanah et al, 2021;Sulistyowati et al, 2022).…”

The issue of plastic pollution in the marine environment is a matter of great concern. Our research presents pioneering findings on sub-surface microplastics in the Indonesian archipelagic waters. Data on microplastic presence in sub-surface water in the Indonesian Archipelagic Water is crucial for expanding our understanding of microplastic distribution from the surface to the bottom layers of the ocean, a research area that has been relatively overlooked. We discovered microplastic particles at 5 m depth below the surface through simultaneous pump method. The highest concentration of microplastics was discovered in Ambon, followed by North Java and North Sulawesi. In contrast, the lowest abundance of microplastics was detected in the Maluku Sea. These findings are consistent with prior studies establishing a relationship between human activity–as indicated by population density–and microplastic pollution. However, our results indicate that levels of microplastics in Ambon were significantly higher than those found in other sampled areas, particularly compared to North Java, which boasts the highest population density in Indonesia. This disparity is likely due to a faster seawater flushing rate and shorter water residence time in North Java relative to Ambon. The origins and pathways through which these microplastics are introduced into Indonesian archipelagic waters remain uncertain. Based on particle composition (52.73% fibers and 51.38% size <500 µm), it appears that they may result from either larger plastic items being broken down during transportation over long distances by prevailing currents from input from coastal areas or as a byproduct of local activities. Additional research is necessary to gain a comprehensive understanding of microplastic in water columns. This includes investigating the fate of microplastics and examining their impact on marine organisms within this treasured ecosystem. Moreover, it is important to develop methods for mapping the worldwide distribution of microplastics.

“…Indonesia has polluted seas, rivers, coral layers, and mangrove banks, besides that, 4 of the 20 polluted rivers in the world are in Indonesia, and the Indonesian government has declared a "garbage emergency" along the 6kilometer coastline on the island of Bali. Changes and damage in the coastal areas of Indonesia have also occurred in DKI Jakarta (Cordova et al, 2022). According to Indrasari, siltation of the coast has been caused by river water entering the coastal area containing a high concentration of suspended solid sediments and soil erosion from the watershed (DAS) carrying sediment and chemical residues to estuaries and the coastal regions.…”

Designing the Structure of the Environmental Education Curriculum Through the Landscape and Contextualism Approach in Indramayu Regency, Indonesia

Disasters and environmental damage that are happening globally are currently important concerns. The current decline in environmental quality causes us to consider and relate this incident to the educational process. Meanwhile, education is the right tool to build a community that cares about the environment and applies sustainability principles and environmental ethics. The curriculum is a dynamic learning tool, and it must continue to develop and keep up with environmental changes. To support sustainable environmental education curriculum development, the form of the curriculum must synergize between theory and real-life (contextual) in the place of the curriculum so that students and teachers can work together in studying their environment (landscape). The purpose of this study is to see how the landscape and contextual conditions of Indramayu Regency are, how the curriculum used at the high school (SMA) level, especially subjects that are integrated with environmental material, and how the curriculum design follows the landscape and contextual conditions of Indramayu Regency and coast. The qualitative method is used with gap analysis (GAP Analysis) and GIS (Geographical Information System) analysis to support the research objectives. Researchers conducted seven stages, grouped into three groups: process, analysis, and output. Landscape Indramayu is divided into 2 (two) parts, namely land and sea (coastal). Results of curriculum analysis show that 5 (five) subjects have integrated environmental material, namely biology, physics, chemistry, geography, and entrepreneurship. Curriculum design is divided into 2 (two), 1. provides learning directions with topics according to the material in the curriculum and syllabus but adds material according to the landscape and context of Indramayu and coastal characteristics, while the 2nd design. Provides direction materials that do not yet exist and need to be added to learning, matters relating to Indramayu's landscape and contextual conditions, and coastal states in general (national/global). So, that in the future, the material contained in the curriculum, syllabus, and other learning tools can be designed and developed according to the landscape and contextual conditions of the coastal area to create a sustainable environment.
