BMKG menargetkan pengurangan debu vulkanik erupsi Gunung Anak Krakatau dalam 1-2 hari melalui operasi modifikasi cuaca menggunakan dua metode: penyemprotan air plus surfaktan saat langit cerah, serta penyemaian awan untuk memicu hujan ketika awan sudah tumbuh. Operasi ini digelar dari posko Semarang dan Kertajati dengan dukungan pesawat dari Kalimantan, dengan catatan efektivitas bergantung pada ada tidaknya letusan baru. Selain itu, kekeringan akibat El Nino masih di fase sangat kuat dan diproyeksi mulai melemah pada Oktober, dengan musim kemarau berakhir sepenuhnya pada November.

Poin-Poin Utama

BMKG targets reduction of Anak Krakatau volcanic ash within 1-2 days via weather modification operations.
Operations employ two methods adapted to atmospheric cloud conditions.
First method: aircraft spray water mixed with surfactant into cloudless atmosphere to bind ash particles and accelerate fall.
Surfactant acts as dust-binding agent causing volcanic particles to fall faster.
Second method: when clouds form, aircraft use water mixed with cloud-seeding material to activate clouds and trigger rainfall.
Operations aim to reduce ash dispersion impact on affected regions including Jakarta.
Operations executed from command posts in Semarang and Kertajati, not Jakarta.
Aircraft deployed from Kalimantan to Semarang.
Effectiveness depends on Anak Krakatau eruption activity; new eruptions would pose additional challenges.
Drought situation currently at very strong El Nino phase coinciding with dry season.
Peak drought conditions expected to persist through end of September.
El Nino influence projected to begin weakening in October as rainy season starts in parts of Indonesia.
Dry season generally expected to end by November.
El Nino-driven drought issues expected to gradually resolve by November.
Conferences press occurred in Jakarta on Monday following coordination meeting with forest HGU holders.
