Abstract

Erupsi vulkanik pada waktu yang lama dapat membahayakan keselamatan masyarakat dan aktivitas penerbangan. Radar cuaca dapat dimanfaatkan untuk monitoring dan identifikasi sebaran debu vulkanik secara real time. Penelitian ini memanfaatkan radar Gematronik dengan produk yang digunakan antara lain: CMAX, VCUT, dan CAPPI sehingga dapat menganalisis debu vulkanik yang dihasilkan oleh erupsi gunung berapi. Dalam kasus kejadian erupsi Gunung Agung tanggal 28 Juni 2018 didapatkan nilai reflektivitas maksimum mencapai 30-35 dBZ, sedangkan pada produk VCUT didapatkan ketinggian kolom debu vulkanik mencapai 7.5 km. Jenis material erupsi dapat diketahui dengan produk VCUT. Produk CAPPI V yang telah ditentukan batasnya yaitu 3 km, 5 km, dan 7 km menggambarkan arah gerakan debu vulkanik berdasarkan lapisannya. Arah sebaran debu vulkanik dominan ke barat dan barat daya. Dilihat secara horizontal maupun vertikal, debu vulkanik mempunyai karakteristik yang khas yaitu nilai echo reflektivitas menurun seiring menjauhi pusat erupsi.

Abstract

This paper discusses the relationship between changes in human activities and deforestation with the condition of pollutant concentration parameters in an area using the Google Earth engine (GEE) method. By applying the Systematic Literature Review method, it is expected to provide an explanation of changes in pollutant conditions, such as concentration patterns of CO, NO2, SO2, O3, HCHO, PM2.5, and PM10 as a result of changes in human activity and deforestation. Human activity patterns may change due to certain events or rules that force humans to follow them. A clear example is the lockdown event during the Covid-19 pandemic that resulted in restrictions on human activities, especially outdoor activities. Similarly, deforestation is the process of significant reduction of forest area through tree felling, forest burning, or other land use changes that result in loss of tree cover and alter forest ecosystems. Both of these events impact the environment and air quality in the region, such as affecting air pollution concentrations. In various studies, changes in human activities and deforestation have been shown to have a significant relationship and influence on air quality concentration parameters in a region.
