Abstract

Penelitian ini merupakan lanjutan dari penelitian sebelumnya tentang peramalan EUR/USD menggunakan metode RBF-NN (Radial Basis Function – Neural Network) yang diop­timasi dengan Algoritma Genetika. Metode yang ditambahkan adalah GRNN (Generalized Regression Neural Network). Sistem RBF-NN dapat diterapkan pada data dengan karakteristik nonlinear dan fluktuatif seperti data EUR/USD, sementara GRNN dapat bekerja dengan baik jika data training tersedia dalam jumlah banyak. Tingkat keakuratan dari peramalan di­tun­jukkan lewat nilai MAPE (Mean Absolut Percentage Error). Dari hasil percobaan, metode GRNN tidak memiliki nilai MAPE yang lebih baik daripada RBF-NN baik pada data daily low maupun data daily high. Teknik pencarian algorima genetika di dekat bobot RBF-NN terbukti lebih efektif daripada pen­dekatan fungsi GRNN dengan spread kecil pada kasus mata uang EUR/USD.

Abstract

The covid-19 pandemic has had an impact on the education sector in Indonesia, since March 2019 education at all levels has been carried out online. Various problems arose during the distance learning process, so the government issued a Joint Decree of 4 Ministers regarding the implementation of face-to-face learning, the central government has authorized local governments to permit face-to-face learning in 2021. As a form of community service from The Bali Nahdlatul Ulama Institute of Science and Technology carried out PHBS educational activities as an effort to anticipate the spread of Covid-19 in the Budi Utama Kerobokan Junior High School. The methods used are counseling, distribution of information brochures, regarding PHBS and efforts to prevent Covid-19, as well as training and mentoring PHBS in the school environment. Based on the results of the evaluation, data obtained from questionnaires to 65 respondents consisting of students, teachers, and school residents as much as 100% have complied with health protocols in the school environment and 95.4% have implemented the PHBS movement in schools (Figure 4). This training activity is expected to increase the knowledge and awareness of school residents and the surrounding community in anticipating the spread of Covid-19 in the school environment, complying with applicable health protocols, and creating a clean and healthy school environment. Key words: Face-to-face Learning; Covid-19 health protocol; PHBS educational activities.
