Abstract

Abrasion of vehicle tires produced on highways on the imaginary line of Yogyakarta from Bantul up to Sleman Regency with different elevations has the potential to be a source of microplastics in the air and can contaminate rainwater. This study aims to determine the abundance and characteristics of microplastics in rainwater that falls on highways with different elevations in Yogyakarta Province. The study began with determining the sampling point and taking rainwater samples on the highway around Bantul Market, Tugu Monument, and Kaliurang km 14. Eight samples on different days were taken at each sampling point, as much as 250 mL/sample. Rainwater samples were filtered, microplastic abundance was calculated (particles/L), and grouped based on the shape, color, size, and polymer type. The content of microplastics on highways at different elevations in Yogyakarta Province was not significantly different, with an abundance range ranging from 200 to 484 particles/L. Vehicle density, light intensity, air temperature, and wind speed correlated with the abundance of microplastics in rainwater. The dominant characteristic is black fiber, 101-500 µm, and polyisoprene. Microplastics in rainwater that fell on the highways of Yogyakarta Province with varying elevations did not have different abundances but had the same characteristics.

Abstract

Indonesia's warm and humid tropical climate provides an ideal setting for the flourishing of fungi. Fungi are pivotal in the intricate balance of nutrient cycles and soil fertility within forest ecosystems. They can be broadly categorized into two types: microscopic fungi, which are minuscule and require observation under a microscope, and macroscopic fungi, which can be identified based on visible morphological features without additional tools. Forests, with their limited sunlight and high humidity due to the dense canopy of trees, serve as fertile grounds for a myriad of fungal species. This research aims to analyze fungal diversity using the exploratory survey method, involving direct search and observation of macrofungi. The sampling was conducted in May 2023 within the Wisdom Park UGM area, covering an area of 3,762.12 m² with coordinates 7° 46'09"S 110°22'59"E. The findings revealed a commendable diversity in terms of shape and size. However, the color palette of fungi in the area exhibited limited variation, primarily consisting of subdued white and brown hues. Some identified fungal species include Ganoderma sp., Mycena sp., Trametes sp., Lepiota cristata, and Panaeolus fimicola. These fungi predominantly thrived on substrates such as trees, soil, leaf litter, and decaying wood.
