This study reports on plastiglomerate and other new forms of plastic pollution in the tropical marine continent of Indonesia. Twenty-five samples were collected from an island beach in the Java Sea where plastiglomerate, plasticrusts, and pyroplastic were formed by the uncontrolled burning of plastic waste. The most common plastic types were polyethylene and polypropylene (PE/PP), as shown by ATR-FTIR spectroscopy. However, acrylates/polyurethane/varnish (PU) and a copolymer of styrene and acrylonitrile were found as well. This suggests that plastiglomerates can form from a wider variety of plastic polymers than previously reported. FTIR analysis also indicates thermo-oxidative weathering, making the charred plastic more brittle and susceptible to microplastic formation. A subset of the samples was analyzed for associated chemical contaminants. One plastiglomerate with a PU matrix showed high concentrations of phthalates. All samples had high concentrations of polycyclic aromatic hydrocarbons (PAHs), likely due to the burning of the plastic in open fires. The burning leads to a change in the physical and chemical properties of the plastics contained in the plastiglomerates. Plastiglomerate and plastic waste of similar origin are therefore often more weathered and contaminated with organic pollutants than their parent polymers. The highest PAH concentration was found in a plastitar sample. Plastitar is defined as an agglomerate of tar and plastics that adheres to coastal rocks. In contrast, our study documents a more mobile, clastic plastitar type. This clastic plastitar could pose an additional ecological risk because of its mobility. These new types of plastic pollution could be an important vector for chemical contamination of nearby coastal habitats such as coral reefs, seagrass meadows, and mangroves.

“…Marine pollution is a common issue in Indonesia's archipelago, particularly in the coastal zone, where the dynamic and change in water quality parameters vary depending on the source intake, season, and oceanographical states (Wisha et al, 2022). The increase in the industrial regions and the anthropogenic activities in many capital cities contributes to the increase in marine pollution cases (Qu et al, 2018).…”

Due to rapid urban development in the coastal area of the East Aceh Regency, water quality degradation and marine pollution issues become the primary concern in this region. Moreover, seasonal observation of water quality and phytoplankton has yet to be assessed. This study aimed to determine the control of seasonal water quality and nutrients over phytoplankton abundance throughout the East Aceh coast. Direct field measurements and laboratory analyses were performed to collect the primary data, whereby the sampling period was conducted during the displacement toward the ebb tide. We assessed the water quality parameters using a modified CWQI (coastal water quality index). Furthermore, linear regression and principal component analysis were performed as the basis of statistical analyses. The phytoplankton abundance was higher in April than in September, with most Bacillariophyceae and Dinophyceae in all observed stations. Except for DO and turbidity, the assessed water quality parameters (temperature, TDS, conductivity, salinity, sulfide, and TOM) are feasible for marine biota. Of particular concern, the East Aceh coast is characterized by poor-good water quality, with the CWQI value ranging from 40 to 90. Based on the regression and PCA analyses, N and P nutrients significantly control the phytoplankton abundance like a "seesaw" between April and September, with a respective coefficient determination of about 50%. Because of the tremendously high phosphate observed in April, the water condition tended to be P-limited and vice versa for September. On the other hand, instead of evoking the phytoplankton growth, each water quality parameter has a specific influence in characterizing phytoplankton communities in the study area.

Massive production of disposable plastic that is not supported with proper plastic waste management has created an environmental problem. One solution that could be done to address this situation is by transforming plastics into chemicals through pyrolysis route. An experimental study of pyrolysis from polyethylene (PE) and polypropylene (PP) has been done by catalytic method and utilization of low-cost natural zeolite in a semi-batch reactor. A low-cost natural zeolite made from acid-treated zeolite with 1 M HCl solution denoted as HZ. The prepared HZ catalyst was then carried out under pyrolysis reaction at 350, 400, 450 o C for 60 minutes. The chemical products composition from this reaction was analyzed using Gas Chromatography-Mass Spectrometry (GC-MS). According to the analysis result, a low-temperature reaction of pyrolysis could produce wax in all variant types of feed. Utilization of HZ catalyst could reduce formation wax while also increasing the yield of oil products after the reaction. Catalytic pyrolysis using HZ for PE and PP plastic feed yields oil products up to 67% and 70%, respectively. The composition of oil products mainly consisted of para n, ole n, and alcohol compounds. The temperature optimum for the catalytic reaction could produce the highest para n and ole n products at 400°C. Additionally, utilization of low-cost natural zeolite could improve pyrolysis reaction's performance from PP to produce yield ole n products from 39-62%. Statement Of NoveltyPlastics waste is threatening the environment due to its di culty in degradation. Pyrolysis of plastic by using catalysts would improve the oil products. Natural zeolites are low-cost minerals and are abundantly available throughout the world. The novelty of this study is to investigate the local natural zeolites in Indonesia as a cost-effective catalyst for application in polyole ns pyrolysis. The oil yield and products selectivity improved signi cantly after using the natural zeolites. The oil composition identi ed would be potentially utilized as chemicals and fuels. Finally, the catalytic pyrolysis of plastic waste using low-cost local catalysts will overcome the environmental problem and create the circular economy of plastic.
