Abstract

As much as 15–40% of all plastic that is dumped into the sea will undergo degradation into microplastics. This research was attempted to analyze the content of microplastics on the coast of Padang and to analyze the correlation between microplastic concentrations with pH, Dissolved Oxygen (DO), temperature, and rainfall. The characteristics of the microplastics analyzed were concentration, color, shape, dimensions, and type of polymer. Illustrations were taken at 9 points with a frequency of 3 times. The concentration of microplastics in the sample is calculated by calculating the number of microplastic particles per unit volume of water or dry sediment mass units. Characteristics of color, shape, and size were analyzed using a microscope, while the type of polymer was analyzed with Fourier Transform Infra Red (FTIR) spectroscopy. The average microplastic concentration in the water illustration is 1.667– 6.667 particles/L and 54.882–84.544 particles/ kilogram in the sediment illustration. The dominant microplastic found was in the form of fiber with a percentage of 95% in the water samples and 79.012% in the sediment samples. The dominant color found is blue with a percentage of 47.619% in the water illustration and 65.432% in the sediment illustration. The most commonly found microplastic size is Large Microplastic (LMP) with a percentage of 76.190% in water samples and 64.198% in sediment samples.

Abstract

Mesin produksi, proses panas, aktivitas berulang, dan penggunaan alat pelindung diri adalah semua elemen industri pengolahan biskuit yang dapat memengaruhi kenyamanan kerja pekerja. Studi ini menyelidiki penggunaan alat pelindung diri, persepsi lingkungan kerja, dan keluhan kesehatan subjektif pekerja yang bekerja di pabrik biskuit di Kota Medan. Metode kuantitatif deskriptif yang digunakan dalam penelitian ini adalah pendekatan cross-sectional. Data dikumpulkan melalui kuesioner Google Form kepada 20 pekerja di bidang oven, pemanggang, penggorengan, dan mesin produksi yang dipilih secara purposive. Untuk mendukung konsistensi instrumen, distribusi frekuensi, persentase, dan uji reliabilitas Cronbach's alpha digunakan. Hasil penelitian menunjukkan bahwa 70% responden merasakan area kerja bising, 65% merasakan area kerja panas, 85% selalu menggunakan pakaian kerja khusus, 80% menggunakan APD sesuai prosedur, dan 70% menggunakan sarung tangan. Lelah setelah bekerja sebesar 65 %, kram otot sebesar 60 %, berkeringat dan haus berlebihan masing-masing sebesar 55 %, dan kesulitan berkonsentrasi sebesar 50 % adalah keluhan kesehatan subjektif yang paling sering dilaporkan.
