Abstract

In the current digital era, the role and strengthening of literacy at the high school and equivalent levels is significant. It aims to ensure that students receive assistance and learn about the development of this technology. Teenagers are required to use technology not only well but also appropriately. 'Goes to School' Literacy Strengthening Activity is one way for students to understand what information is appropriate to share and pass on to the community through various media. Of the four schools visited at SMK Negeri 1 Pangkalpinang, SMK Negeri 1 Simpang Katis, SMK Negeri 1 Sungailiat, and SMK Negeri 1 Simpang Rimba, the team found that almost all students use Android and nearly all students use social media in their daily lives. However, quite a few of them need help understanding the good and wise use of social media. Through this literacy-strengthening activity, the team also invited high school and vocational school students to intensify the importance of literacy in various media, including participating in Literacy School activities.

Abstract

Polusi udara merupakan masalah masalah lingkungan yang berdampak langsung pada Kesehatan dan kualitas hidup manusia. Tujuan dari penelitian ini adalah untuk menggunakan algoritma Isolation Forest berbasis Unsupervised Learning, untuk menemukan anomali dalam data kualitas udara dan mengetahui situasi yang tidak normal dengan cepat dan akurat tanpa memerlukan label. Isolation forest dipilih karena efisien dalam menangani data yang besar dan bekerja dengan cepat dalam ruang fitur tinggi dibandingkan dengan algoritma yang lain. Penelitian ini mengimplementasikan algoritma isolation forest untuk dilakukannya identifikasi outlier pada data kualitas udara, khususnya parameter karbon monoksida (CO), nitrogen dioksida (NO?), nitrogen oksida (Nox), dan benzene (C6H6) dari dataset UCI Air Quality. Penelitian ini dilakukan dengan studi literatur, pengumpulan data, preprocessing (pembersihan data dan penanganan nilai hilang), analisis eksploratif, implementasi algoritma, serta visualisasi hasil. Hasilnya, dari total 9357 data, terdeteksi 468 anomali (5%) dengan karakteristik lonjakan nilai ekstrim seperti CO 8.1 mg/m³ dan NO? 187 µg/m³. Visualisasi grafik temporal dan boxplot memperkuat penelitian ini, dengan menunjukkan distribusi anomali yang tersebar. Sehingga, pendekatan ini bisa digunakan sebagai sistem peringatan dini terhadap lonjakan polusi udara yang berbahaya, sehingga berkontribusi dalam sistem monitoring kualitas udara otomatis yang lebih adaptif dan real-time.
