Background • 2005: APRSAF (Asia Pacific Regional Space Agency Forum),
Fukuoka, Japan, 2005 JAXA (Japan Aerospace Exploration Agency) offer little experiment (< 5 kg) at JEM ‘KIBO’
• LAPAN –ITB accepted the offer and proposed a research proposal
• 2007: Feasibility study at ITB
• 2008: Preliminary Experiment at JAXA
• 2009-2012: Ground based experiment

Earth and Space Environment is Different
Elevated levels of ethylene
or CO2, reduced levels of
available O2, all contributed
factors to metabolic stress
in plants, are all common in
closed environments such as
those experienced in orbital
vehicles

Preliminary Study : Ground Based Experiment
• Research on the effect of space environment in ripening process has not been conducted.
• 3D clinostat, equipped with
2 rotation axes and closed chamber made from glass was made to mimic microgravity. 3D clinostat developed at ITB
ANIMASI KLINOSTAT

Preliminary Conclusion
• The physical and physiological analysis showed that banana shelf life was longer at microgravity simulation condition
• Molecular analysis also showed that Microgravity simulation using 3D clinostat can affect the ripening related gene expression.

Space Experiment Proposal
• Conduct fruit ripening process study in real microgravity condition.
• Observe Fruit ripening process using data record (physical and environment condition)
• Analyze returned sample for Transcriptomics
and Metabolomics
