Article
Indonesia, the world's largest archipelagic country and the fourth most populated nation, has struggled with coastal water pollution in the last decades. With the increasing population in coastal urban cities, more land-based pollutants are transported to the coastal water and adversely affected the tropical ecosystems. This paper provides an overv...

Quantifying and characterizing groundwater flow and discharge from barrier islands to coastal waters is crucial for assessing freshwater resources and contaminant transport to the ocean. In this study, we examined the groundwater hydrological response, discharge, and associated nutrient fluxes in Dauphin Island, a barrier island located in the nort...
Article

Subterranean estuaries the, subsurface mixing zones of terrestrial groundwater and seawater, substantially influence solute fluxes to the oceans. Solutes brought by groundwater from land and solutes brought from the sea can undergo biogeochemical reactions. These are often mediated by microbes and controlled by reactions with coastal sediments, and...

Mobile Bay, the fourth largest estuary in the USA located in the northern Gulf of Mexico, is known for extreme hypoxia in the water column during dry season caused by NH4⁺-rich and anoxic submarine groundwater discharge (SGD). Nutrient dynamics in the coastal ecosystem point to potentially elevated microbial activities; however, little is known abo...
Article
Full-text available
In this study we evaluated the magnitude and seasonal variations of natural and anthropogenic fluxes of inorganic (NO3⁻, NH4⁺, and PO4³⁻) and organic (DON and dissolved organic carbon) nutrients delivered by submarine groundwater discharge (SGD) and rivers to the fourth largest estuary in the USA, Mobile Bay in Alabama. To identify the sources of S...
Thesis
Full-text available
Submarine groundwater discharge (SGD) is known to transport terrestrial nutrients and other potential pollutants to coastal areas around the world. However, SGD studies in tropical developing regions, such as Southeast Asia, are scarce, even though this area is hypothesized to be an SGD hotspot due to favorable meteorological and hydrological condi...
Article
Submarine groundwater discharge (SGD) can be an important pathway for chemical or biological pollutants from land to the ocean around the world. However, studies on the microbial communities associated with SGD in Southeast Asia, which has been hypothesized as SGD hotspot, remain scarce. In this study, we examined the microbial community compositio...
Article
The goal of this study was to investigate what kind of impact the removal of particulate organic matter with 33 μm rotating belt filter (RBF) (as a primary treatment) will have on the membrane bioreactor (MBR) performance. Two small MBR pilot plants were operated in parallel, where one train treated 2 mm screened municipal wastewater (Train A) and...
Article
Groundwater discharge is known to transport nutrients into estuaries at several locations around the world. However, few studies report groundwater-associated nutrient fluxes from tropical developing regions such as Southeast Asia, even though this area shows the strongest human modifications in the coastal zone worldwide. We investigated groundwat...
Article
Full-text available
In tropical karstic regions, knowledge about the timing and quantity of land–ocean groundwater nutrient fluxes is important, as those nutrients may affect coastal ecosystems and contaminate coastal springs. High aquifer permeability of the karst, combined with high recharge and discharge during heavy rain events, leads to a close connectivity betwe...
Poster
Full-text available
Submarine groundwater discharge (SGD) is increasingly recognized as an important pathway for nutrient transport from land to ocean. It can be expected to be of particular interest in Indonesia, which has one of the longest coastlines in the world. Abundant fertilization and sewage nutrient inputs into groundwater occur in Indonesia, thus anthropoge...

BUKU INI disusun untuk mengingatkan kita pada kejadian tsunami di Ambon pada tahun 1950. Saat itu mereka menyebutkan gempa bumi dengan istilah “Tanah Goyang” sedangkan “Air Turun Naik” sebagai istilah yang kita kenal sekarang dengan tsunami. Kejadian ini dialami oleh tiga negeri (nama untuk wilayah setingkat dengan desa) di Ambon yaitu Negeri Hutum...
Conference Paper

The main purpose of this research project, jointly financed by the Norwegian Research Council (grant no. 211055/030) and Salsnes Filter AS, was to define the particle size cut-off of organic matter prior to biological nutrient removal (BNR). The long term objectives were to reduce the energy consumption in the aerobic process and increase the produ...

Project
1) Create a platform for an interdisciplinary group of SGD experts to initiate and intensify collaborative ties across disciplines 2) Improve individual methodologies by groundtruthing through interdisciplinary intercomparison on the basis of a method intercomparison experiment at one site at the same time, and 3) Provide a method catalogue which outlines optimal combinations for qualitative and quantitative SGD investigations
Project
base the historical tsunami data, we try to simulate potential of tsunami hazard at Ambon Island. This result will be used for TTX at Ambon Island in 2016

Hypothesis: Submarine groundwater discharge from tropical islands deserves more attention because of intensive transport function and sensitive coastal ecosystems.
