Volcanic Ashes

these are my tweets about volcanic ashes earlier this morning:

@hgunawan82: “@agustiana81: Abu vulkanik itu apa? Dan kenapa warnanya kayak gitu? Kira2 bs dipakai apa ya?#anakbertanya @d_erwin_irawan bisa jawab?

@d_erwin_irawan: @hgunawan82 @agustiana81 #anakbertanya:ini summarynya:

letusan gnapi melonyarkan materi lava pijar n piroklastik (px). Px adl materi padat. Materi padat sehalus abu-sebesar rmh. Materi besar&berat jatuh tdk jauh dr kepundan.Materi halus akan terbang jauh terbawa angin. Warna abu gnapi abu2 muda-gelap krn kaya mineral logam. Abu/tanah gnapi subur, krn itu sering jd campuran pupuk,jg jd camp semen krn mengandung unsur logam, jd campuran bahan keramik, n bahkan di banyak tempat bahkan bisa jd campuran kosmetik mama :-). Lengkapnya menyusul 🙂 jgn lupa pakai masker ya.

About the author

My current focus is how to provide the hydrostratigraphy of volcanic aquifers in Bandung area. The research is based on environmental isotope measurement in groundwater and morphometry. My work consists of hydrochemical measurements. I am using multivariate statistical methods to provides more quantitative foundation for the analysis and more insight into the groundwater behavior, especially its interaction with surface water. I use open source apps like R and Python to do the job. In my spare time, I also have a side project to promote open science in Indonesia's research workflow. One of my current focus is promoting INARxiv, as the first preprint server of Indonesia (osf.io/preprints/inarxiv) and serving as ORCID and OSF (osf.io) ambassador. Research interest: Hydrochemistry, multivariate analysis, and R programming. Blog: dasaptaerwin.net, derwinirawan.wordpress.com. (https://orcid.org/0000-0002-1526-0863)
