Mitigasi Dampak Abu Vulkanik, Kualitas Udara dan Air Laut Terus Dipantau
Pemerintah memantau dampak ekologis erupsi Gunung Anak Krakatau yang meletus pada 4 September 2026 melalui pengukuran kualitas udara (PM 2,5, PM 10, SO2) dan air laut di Banten serta Lampung. Kualitas udara di Banten, Jakarta, dan Jawa Barat umumnya kategori baik-sedang, meski Sumatera selatan mencatat ISPU sangat tidak sehat—meski belum pasti terkait erupsi karena masih ada karhutla. BMKG mencatat 39 dokumen Sigmet dengan sebaran abu vulkanik bergerak ke arah barat; pemulihan ekosistem pesisir menunggu aktivitas gunung dinyatakan stabil.
Poin-Poin Utama
- Indonesia's Environment Ministry (KLH/BPLH) monitoring air quality and sea water after Anak Krakatau eruption in Sunda Strait.
- Rapid response team deployed to measure ambient air quality and sea water quality in Banten and Lampung coastal areas.
- Local governments ordered to secure clean water sources from volcanic ash contamination.
- Pesisir ecosystem recovery and biological impact handling will proceed after volcanic activity declared stable.
- BMKG recorded Anak Krakatau eruption first detected Friday (4/9/2026) at 23:23 WIB.
- Satellite imagery analysis Sunday (6/9/2026) at 08:00 showed ash spread across Banten, Jakarta, West Java, Lampung, Bengkulu, southern Sunda Strait, and Indian Ocean.
- KLH/BPLH monitoring ambient air parameters including PM 2.5, PM 10, and sulfur dioxide (SO2) concentration.
- Air quality monitoring uses Air Quality Monitoring System (AQMS) and Indeks Standar Pencemar Udara (ISPU) system.
- Air quality in Banten, Jakarta, and West Java generally good to moderate as of 6 September 2026 at 14:00.
- Several locations in southern Sumatra recorded high ISPU values: Bukit Kecil Palembang at 216, Kabupaten Penukal Abab Lematang Ilir at 237, Kabupaten Ogan Ilir at 213.
- Particulate increase in southern Sumatra not yet directly linked to Anak Krakatau eruption due to ongoing forest and land fires.
- BMKG issued 39 Significant Meteorological Information (Sigmet) documents since eruption began 4/9/2026.
- Sigmet on Monday (7/9/2026) at 06:30-09:30 recorded volcanic ash at altitude up to 15,000 feet or 4.57 kilometers.
- Volcanic ash moving west at 15 knots with consistent intensity.
- Ash extends southwest to northwest from surface to 15,000 feet, crossing parts of Banten, southern-western West Java, Lampung, Bengkulu, and surrounding waters.
