Abstract

Election issues are sensitive information among the society because they relate to people's survival in terms of work, economy and education. Election hoaxes where information whose truth cannot be ascertained becomes a weapon used by certain parties to bring down political opponents. Social media such as TikTok is a media that is often used to spread hoaxes because TikTok social media users come from various ages and there is no distance or time between users. In this paper, a mathematical model is presented to see how the equilibrium point is to be free from hoax based on the basic reproduction number R0. The spread of hoaxes on social media occurs if R0 > 1 and does not occur if R0 < 1. The model approach used is the SEIR mathematical model because it is seen that there are people who receive hoax videos (exposed) and then spread them without finding out the truth (infected), and users with this condition it needs to be recovered. The method used in this research is a literature review. The results obtained show that the mathematical model presented shows that the basic reproduction number R0 is zero (R0 < 1). This means that there will be no spread of election hoaxes

Abstract

Salah satu metode pengukuran kinerja dan efektifitas mesin yang digunakan adalah Overal Equipment Effectivennes (OEE). Metode pengukuran ini terdiri dari tiga faktor utama yang saling berhubungan yaitu Availability (ketersediaan), Performance (kemampuan), dan Quality (kualitas). Metode ini merupakan bagian utama dari sistem pemeliharaan yaitu Total Productive Maintenance (TPM). Untuk itu perlu dilakukan perhitungan terhadap nilai Overall Equipment Effectivennes (OEE) untuk mengetahui kinerja mesin penggilingan sheet tersebut dan menganalisis faktor faktor penyebab ketidakefektifan mesin yang mungkin yang terjadi. Dalam rangka pengumpulan data dan juga waktu untuk menganalisa dari tahap pertama sampai tahap selesai, maka dilaksanakanlah metode-metode kerja antara lain yaitu, Metode Tinjauan Pustaka dan Metode Studi Lapangan Berdasarkan pengamatan dan pengolahan data yang telah dilakukan maka dapat disimpulkan bahwa nilai efektivitas mesin roll sheeter tahun 2023 menggunakan metode Overall Equipment Effectiveness (OEE) yaitu nilai Availability 89%, nilai Performance ratio 95% dan nilai Quality rate 99%, sehingga nilai OEE yang dihasilkan adalah 83%. Nilai OEE rendah karena nilai availability tidak mencapai standar yaitu 90%. Nilai OEE yang diperoleh tidak sesuai dengan standar yang ditetapkan oleh Japan Institute of Plant Maintenance (JIPM) yaitu 85%
