This study aims to identify and quantify microplastics in various types of compost derived from household waste, livestock manure, and vegetable straw. The methods used include extraction of microplastics with an acid solution, particle filtration using micron filters, and identification of morphologies and polymers through stereo microscopy and FTIR (Fourier-transform infrared) spectroscopy. The results showed that all types of compost contained microplastics, with the highest abundance in compost mixtures of manure and goat manure (11 particles/kg). Microplastics are dominated by polyethylene and polypropylene polymers, with fiber and filament shape measuring &lt; 2 mm, and most samples are in the high-risk category (Level IV). The conclusion of this study is that commercial compost has the potential to be a major vector for the entry of microplastics into soil ecosystems.

The method used was in the form of secondary data analysis on the rate of animal mortality due to exposure to various types of microplastics. The data are used to simulate the amount of production, annual population, and potential economic losses per cycle and per year. Economic value is determined based on the latest prices, and minimum prices. The results showed that exposure to microplastics in animals led to 20% to 80% deaths, with potential annual losses reaching USD 113,568 in rat farmers, while in ducks, polytetrafluoroethylene (PTFE) exposure led to embryo death by 35% and annual losses of up to USD 6,859,091.14. These findings suggest that the economic impact of microplastics has the potential to outweigh losses due to conventional biological threats such as infectious diseases.

The estuary is important in fisheries, particularly small pelagic fish, related to plankton abundance and aquatic fertility. The recent tendency of the coastal development area raises the establishment of small-scale industries, textile industries, and ecotourism, which carry a significant amount of disposal waste as well as organic matter. The tidal flooding influenced the dynamic of organic matter in Pekalongan, which increased yearly due to climate change. This study aims to determine the content and distribution of nitrate, phosphate, total suspended solids (TSS), and chlorophyll-a (CHA) collected from 2021 to 2024 at four rivers in Pekalongan Regency based on a geospatial approach. The study results showed that the CHA contents from 2021 to 2024 varied from 0.196 to 2.473 µg/L, 0.022 to 0.379 µg/L, 0.002 to 2.414 µg/L, and 0.21 to 3.083 µg/L; TSS contents from 2021 to 2024 varied from 4 to 26 mg/L, 64.7 to 149 mg/L, 16.3 to 214 mg/L, and 19 to 299 mg/L; nitrate contents from 2023 to 2024 varied from 0.004 to 1.31 mg/L and 0.004 to 0.959 mg/L; and phosphate contents from 2023 to 2024 ranged from 0.003 to 0.767 mg/L and 0.001 to 1.017 mg/L. The concentration of CHA and TSS varied each year. However, the existing pattern shows an increase in TSS concentration and a decrease in CHA values, which indicates a reduction in water quality. The nitrate concentration tends to decrease, and the phosphate concentration has increased recently. The dynamic distribution of organic matter occurs due to the influence of tidal currents, longshore currents, and the east monsoon wind.
