Abstract

This article presents studies on the physicochemical quality of oyster mushrooms grown within a housing and controlled by the Internet of Things (IoT). The goals of this study were to assess (1) the impact of indoor air quality on the growth and quality of mushrooms and (2) the antioxidant content of oyster mushrooms. In this study, the air temperature and humidity of oyster mushroom house per unit time was recorded and controlled automatically by an IoT system. Additionally, their physicochemical and microbiological quality were evaluated using physico-analytical instruments, and the potency of their ergothioneine (EGT) content was investigated using the HPLC method. The temperature of the air inside was between 29 and 35 °C, and the relative humidity was between 60% and 90%. The average texture of mushroom is soft.  The average length, width, and height of the fresh mushroom were 41.5 mm, 60.0 mm, and 29.5 mm, respectively. The microbiological test confirmed that there was no salmonella infection in the collected mushrooms. The button-stage mushrooms have less total fungus than the bloom-stage mushrooms. The extraction standard method employs an EGT content of 0.674 mg/g as determined by chromatography data analysis. The oyster mushrooms can be consumed as a healthy meal, and the study of EGT showed also very prospective as one of immunotherapeutic food. Keywords: Ergothioneine, Fibre-reinforced plastic house, Internet of think, Oyster mushrooms

Abstract

PT. XYZ merupakan perusahaan yang bergerak di bidang industri kemasan fleksibel jenis Biaxially Oriented Polypropylene (BOPP). Tujuan dari penelitian ini yaituh untuk mengetahui penerapan program Keselamatan dan Kesehatan Kerja (K3), Identifikasi Risiko dan mengetahui seberapa efektif penerapan program K3 dengan metode HIRADC. Objek dalam penelitian ini adalah seluruh pekerja dengan total 19 pekerja pada area proses produksi kemasan fleksibel. Teknik dan metode analisis data menggunakan deskriptif kualitatif. Metode HIRADC memberikan gambaran yang jelas tentang implementasi di area produksi kemasan fleksibel, yang meliputi identifikasi bahaya, penilaian risiko, dan pengendalian risiko. Data sekunder dikumpulkan melalui wawancara, observasi lapangan, dokumentasi, dan pencarian referensi. Hasil penelitian yang didapatkan pada area produksi kemasan fleksibel terdapat 8 area kerja dengan tingkat risiko yang cukup tinggi. Alat kerja yang tidak bisa dihilangkan adalah alat kerja mekanik yaitu cutter karena setiap stasiun kerja selalu menggunakan cutter, maka dari itu pengendalian yang dilakukan berdasarkan HIRADC yaitu penambahan Alat Pelindung Diri (sarung tangan anti cutter) dengan maksud untuk menurunkan resiko kecelakaan kerja.
