Abstract

Microplastics are a new pollutant in the air, but the determination of the maximum limit of their existence has not been set in regulations. Microplastics found in the air of building spaces are made from plastic waste. The presence of microplastics in the air is influenced by physical environmental factors. Inhaling microplastics can have a detrimental impact on lung tissue. The research aims to create a mathematical model of the effect of ultraviolet exposure, temperature, and humidity on the quantity of microplastics in indoor air. Mathematical models can be used to predict the quantity of microplastics in the air. The type of research is a true experiment with a posttest-only control group design. Air samples are taken daily for 60 days by the passive method by taking dustfall. The parameters measured include the quantity of microplastics, ultraviolet intensity, temperature, and air humidity. Microplastic examination by visual method using a 40-fold magnification binocular microscope. Analysis of the mathematical model of the effect of ultraviolet exposure, temperature, and humidity on the quantity of microplastics in the form of time series data using linear regression. The results of data analysis show that the effect of the panel regression estimation model, in accordance with the empirical data, is the Fixed Effect Model (FEM). The conclusion based on the results of the study shows that physical environmental factors have an influence on the quantity of microplastics in the air, whose existence can be predicted using FEM modeling that has been made.

Abstract

Jenis penelitian ini adalah Kualitatif Deskriptif yaitu memilih individu yang termasuk dalam generasi milenial (kelahiran tahun 1981-1986) yang aktif menggunakan aplikasi shopee untuk melakukan pembelian online. sebagai sampel dan 4 informan yang dianggap memiliki pengetahuan dan informasi mengenai permasalahan yang diteliti yakni 1. Bagaimana persepsi millenial terhadap shopee? 2. Apa yang menjadi alasan para millenial melakukan pembelian di shopee? Data yang dikumpulkan dengan menggunakan instrument berupa: Observasi dan Dokumentasi, serta wawancara secara mendalam terhadap informan. Dari hasil penelitian ini menunjukkan Persepsi milenial umumnya positif terutama dengan kemudahan dalam menggunakan aplikasi namun ada beberapa hal yang perlu ditingkatkan seperti proses pengiriman yang mengalami keterlambatan. Meskipun begitu, secara keseluruhan milenial memiliki persepsi yang baik terhadap e-commece shopee karna banyak kemudahan dan keuntungan yang di berikan oleh pihak shopee itu sendiri. Dari hasil penelitian ini juga diperoleh milenial menggunkan aplikasi shopee karna berbagai alasan seperti platfrom ini menawarkan harga yang murah dan terjangkau yang membuat pengalaman berbelanja menjadi lebih menyenangkan dan dapat memenuhi kebutuhan milenial dalam berbelanja online.
