Abstract

Road dust is a prevalent source of microplastics found in the atmosphere. The primary contributors to the presence of microplastics in dust are vehicle traffic, road surfaces, tire erosion, and road paint. The objective of this study is to categorize the various forms of microplastic pollution present in the road dust surrounding the Angso Duo Jambi market. The research employed a random sampling technique, specifically selecting 4 sample location locations. The total aggregation of microplastics amounted to 1.67 grams. Sample B exhibited the highest prevalence of microplastics, with a distribution of 2.78 grams in the vicinity to the right of Jambi's Angso Duo Market. The analysis of microplastics was conducted using a binocular microscope, Fourier Transform Infrared Spectroscopy (FTIR). The microscopic analysis of microplastic reveals the presence of several forms, namely fibres, fragments, and films. The FTIR study results indicate that polyethylene is the prevailing polymer type. The chemical composition and types of microplastic polymers found near the Angso Duo Jambi market, as determined by the results collected, include polyethylene, polypropylene, and polystyrene. The environmental impact of microplastics is intricately linked to the characteristics of the microplastics themselves, including their kind, size, concentration, and duration of exposure. Further investigation is required to examine the enduring consequences of microplastics on the environment, particularly in relation to the contamination of road dust.

Abstract

Rambutan (Nephelium lappaceum L.) merupakan buah tropis sejenis pokok buah saka yang tergolong ke dalam family sapindaceae. Daging buah rambutan kaya antioksidan dan vitamin bagi tubuh manusia terutama vitamin C dan disukai oleh masyarakat karena bentuknya yang unik (berambut) dan rasa daging buahnya yang manis. Namun, konsumsi buah rambutan ini menyumbangkan limbah yang cukup besar, terutama pada kulit buah. limbah kulit buah rambutan yang cukup besar dapat diolah menjadi produk baru yang memiliki nilai ekonomis dan dapat mengurangi biaya pengolahan limbah tersebut. Pada beberapa penelitian, bagian rambutan yang dianggap limbah ini memiliki aktivitas bioaktif seperti antibakteri, antioksidan, antidiabetes hingga antikanker. Kulit buah rambutan banyak mengandung senyawa fenolik dan turunanya yang dapat dimanfaatkan secara efektif sebagai obat dan inhibitor korosi. Kulit buah rambutan sebagai inhibitor korosi dapat digunakan pada berbagai jenis logam seperti aluminum, baja dan besi serta pada berbagai media asam. Ulasan ini memberikan informasi mengenai sediaan fungsional dari kulit
