Article
The use of tritium isotope is one of the methods for determining groundwater age. It can be used to determine the age of groundwater classified as young. However, if it is the only method used, the results may not be valid. In this study, tritium application in determining groundwater age was evaluated based on deuterium and oxygen-18 isotopes and...
Article
Number of populations, industry, and economic activities in Indonesia are growing rapidly and these impacts on natural environments raise awareness about water quality issue over the country. Bandung Basin, one of the most growing rapidity urban areas in Indonesia, was assessed for NO3− contamination in groundwater systems, and its controlling fact...
Article
One crucial task in groundwater research and management is the estimation of groundwater mixing ratios. Here, estimations of mixing ratios are presented systematically and spatially for shallow and deep groundwater in some areas of excessive groundwater pumping with different magnitudes of groundwater drawdown. The mixing ratios are estimated using...

In the Bandung basin, Indonesia, excessive groundwater pumping caused by rapid increases in industrialization and population growth has caused subsurface environmental problems, such as excessive groundwater drawdown and land subsidence. In this study, multiple hydrogeochemical techniques and numerical modeling have been applied to evaluate the rec...

Conference Paper
One crucial task in groundwater research and management is estimating groundwater mixing ratios. In this paper, we present estimates of mixing ratios for shallow and deep groundwater in an area of excessive groundwater pumping; three depression areas with different magnitudes of groundwater drawdown were analyzed. We estimated the mixing ratio usin...

Bandung basin which located in West Java, Indonesia is a large intra-montane basin surrounded by volcanic highlands. The basin is a highly urbanized area whose population has been rapidly increasing since few decades ago. It is widely believed that the increase of population, as well as industrial activities, will increase the degree of groundwater...
Article
Bandung Basin is a large intra-montane basin surrounded by volcanic highlands, located in West Java, Indonesia. It is an urban area inhabited by more than seven million people. Results of 10 GPS (Global Positioning System) surveys conducted since 2000 to 2012 show that several locations in Bandung basin have experienced land subsidence, with an ave...

The eruptive history of Sembalun–Propok-Rinjani volcanic complexes during the young Quaternary age had been studied. Those young volcanic complexes are as a good geothermal heat source of the Eastern Lombok prospects. The ages of Sembalun volcanic rock complex were formed during the last of 0.45 Ma. The pyroclastics of youngest Rinjani volcanic pro...

Jakarta is the capital city of Indonesia with a population of about 9 to 13 million people, inhabiting an area of about 660 square-km. It has been reported for many years that several places in Jakarta are subsiding at different rates. Over the period of 1982-1997, subsidence ranging from 20 to 200 cm is evident in several places in Jakarta. There...
Article
This study has been conducted on east slope of Mt. Ciremai, a strato-type volcano with elevation of 3072 masl, in Kabupaten Kuningan, West Java, Indonesia. Result of 20 observations had shown that spring discharge varies from 10 l/sec to 400 l/sec, consisted of deviated and isolated groundwater flow patterns. Analysis on available data and facts al...
