During my off time. Karang Sambung (Kebumen) Field Camp 2007

Kuliah lapangan Karang Sambung diadakan sejak tanggal 26 Juni sampai 25 Juli 2007. Dosen anggota KK Geologi Terapan bertugas mengisi sesi geomorfologi. Dr. Budi Brahmantyo dan D. Erwin Irawan, MT ditugaskan untuk mengisi materi tersebut, yang terdiri dari:

1. Analisis dan interpretasi peta geomorfologi
2. Observasi bentuk-bentuk geomorfologi
3. Observasi tanah pelapukan
4. Observasi dan pembuatan penampang sungai

Berikut ini adalah beberapa foto-foto kegiatan tersebut.

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)
