Nalareksa is a method of air analysis by using water as a mediator for the research.To investigate out the elements in air, we could use water as a mediator for the container of the elements from the air if we know the equilibrium condition between air and water. Nalareksa was inovated by Prof. Ir. Hardjoso Prodjopangarso as his intention for his research could be useful by small people in Indonesia. It is used as a method to determining the air condition in the space of building for civil engineer. Nalareksa is very useful for engineer to plan dimension of windows, ventilation and air circulation system of a building. By these artworks, I would like to express how the condition of our air is affecting our precious water condition. Water is a very strong solvent dissolving many types of substances especially Oxygen and Carbon Dioxide (carbonation), which are known as “hydrophilic” (water-loving) substances. This is why analysis of the air contained in bubbles in the ice core can reveal the palaeocomposition of the atmosphere, inparticular CO2 variations. An ice core itself is a core sample from the accumulation of snow and ice over many years that have re-crystallized and have trapped air bubbles from previous time periods. The composition of these ice cores, especially the presence of hydrogen and oxygen isotopes, provides a picture of the climate at the time.

On global advance technology development, industries and also housing, we produces waste that up until present days have been major issues on how they were processed and what negative effects on the environment they are causing. Mainly rivers and oceans are used as their final waste disposal sites while emission of transportations and working process are causing air pollutions. Nalareksa project is seeking the relations between air and water using traditional hydro labs working method to analyze the substance they are carrying in and presenting them as an artwork in forms of installation, experimental audiovisual instruments and performance. So far, this project has been developed into the second series of sample gathering and environment analyzing.

Re-Liquify Sound Installation 0.2 at Art, Culture and Climate Change Dialogue –

Beijing, China – October 2008

Description

An analog and digital composition sound installation in an exhibition in Central Academy of Fine Art, Beijing China 10 October 2008. Space Environment Analyzing: Wet temperature and dry temperature are a necessary variable in nalareksa method to determine the amount of CO2 and O2 level inside the space. The variables will be used in calculation process in Nalareksa. By using modified analog thermal sensors, the installation produced synthetic sounds from the temperature of the space. 4 sensors was used in this installations which are 2 wet thermal sensors, each was placed inside the water in the reaction tubes and 2 dry thermal sensors, each was placed on the top inside of the reaction tubes. Wet thermal sensors are used to measure water temperature while dry thermal sensors are used to measure the air temperature condition. The sound then combined with sounds from quadraphonic ears on each tube which was processed by a customize analog mixer and temperature analyzer. A sound composition of the sample gathering process created on this installation.
