Belajar membimbing

Sudah mulai belajar membimbing S1, jadi pembimbing ke-2. Pembimbing ke-1 nya Pak Budi. Alhamdulillah ada dukungan dana penelitian dan enam orang mahasiswa S1 Teknik Geologi yang penuh semangat (walaupun kadang masih harus didorong-dorong, hehe, but that’s ok. I have walked in their shoes and thesis life was proven to be hard). Keenam bimbingan pertama saya itu:

  1. Jaka Satria
  2. Rahmat Arif
  3. Ali Lukman
  4. Zidni
  5. Tedy Cahyadi
  6. Kurniawan

Daerah pemetaan di Bandung Utara dengan studi khusus geomorfologi (morfometri) dan sedikit hidrogeologi (yaitu pengukuran laju infiltrasi di lapangan).

Have a nice field work and please be safe.

What is volcanic hydrogeology

Definitions of Volcanic Hydrogeology

(extracted from various sources and experiences)

Hydrogeology is the branch of geology that deals with the occurrence, distribution, and effect of groundwater. Contrary to popular belief, groundwater is not typically found underground in the form of a body of water, similar to rivers or lakes. Rather the water is contained in the pores, cavities, and voids interspersed among rocks, gravel, sand, and soil in the earth’s subsurface. When useful extractable quantities of water in these geologic formations are found, they are known as aquifers; aquifer means, “water bearer.”

Volcanic (Collins Essential English Dictionary 2nd Edition 2006 © HarperCollins Publishers 2004, 2006)

  1. Volcanic - relating to or produced by or consisting of volcanoes
  2. volcanic - igneous rock produced by eruption and solidified on or near the earth’s surface; rhyolite or andesite or basalt; “volcanic rock includes the volcanic glass obsidian”

 

Volcanic Hydrogeology is the branch of hydrogeology that deals with with the occurrence and distribution of aquifer system and behaviour of groundwater as resources and as agents in volcanic environment.

Abstract (no more than 200 words)
Volcanic slopes are important sources of water. Due to altitude effects they receive significant amounts of precipitation whereas the lower regions often receive far less (<500 mm/year). In densely populated tropical regions, like Java, Indonesia, this water source is of increasing importance both for irrigation and domestic uses. The use of water from volcanic slopes is, however, not without risk as volcanoes are very important sources of toxic contaminants. The relatively small discharge volume and large spatial variability of the volcanic deposits make it difficult to assess the characteristics of the local groundwater systems and to calculate the water balance.
This paper describes a methodology to analyse both water quality and quantity using spring discharge information and relate it to volcanic geomorphology.
As case study, more then 100 springs are monitored and analysed on Mt. Ciremai, central Java, Indonesia. The results show radial flow patterns, a dependency on slope aspect and altitude and lithology. The aquifer system was found to be a combination of porous (several meters) and fractured rock that is built up of lava and volcanic breccias.
This paper will elaborate on the relationship between volcanic geomorphology and hydrology that was found and discuss how this information could be used for assessing the spatial patterns of local groundwater systems on volcanic slopes.
