The Scientific Writing Competition “Clinostat Experiment”
• Theme: Space Simulation on Life Science” • In cooperation with the School of Life Sciences
& Technology, Institut Teknologi Bandung(SITH-ITB) and the National Institute of Aeronautics and Space (LAPAN).
Clinostat • Using a Clinostat provided by LAPAN,
• http://iss.jaxa.jp/en/kuoa/news/movie_1506/
A “Clinostat” is an experimental device that simulates microgravity environments
Competition Process • The five finalists were selected from among 28 proposals from
Indonesian high schools. • Finalist’s proposals were selected by a panel of judges from
LAPAN and SITH-ITB, based on their experiment’s feasibility and the potential benefit of its results.
• Each experiment were conducted by a team of three students with one assisting teacher.
• The winners of the final competition was decided based on their experiment’s process and results.
These experiment ideas from Indonesia’s next generations are highly anticipated to one day grow into ideas for microgravity experiments in the Kibo module on the International Space Station, and to contribute to better utilization of the space environment by Indonesia and other Asia-Pacific countries. The competition is held as a part of “Space Science Festival,” an annual event organized by LAPAN to celebrate World Space Week (worldspaceweek.org).

The Final Presentation

physically develops after birth or hatching, involving a
conspicuous and relatively abrupt change in the animal's
body structure through cell growth and differentiation.
• Mealworms has complete metamorphosis stage
• Mealworm is an object that relatively easy to find, adaptivable and usable as decomposer
Hypothesis: There is the effect of microgravity on metamorphosis time and morphology of mealworms (Tenebrio molitor)
31 days Observations The objects under microgravity experiment have metamorphosis time longer than those under normal condition This is thought because of the fisiological adaptation
of object on clinostat, that affect the stimulation or inhibition of certain metamorphosis’ hormones
The morphology difference between mealworms beetle under microgravity and normal condition is not significant, (1 of 12 is different, the object has problem on its motility (motion ability) , beetle movement seemed to drag.
The Effect of Microgravity Environment Simulation to the Growth of Pleorotus ostreatus
• Kingdom : Fungi
• Divisi : Basidiomycota • Kelas : Agaricomycetes • Ordo : Agaricales • Famili : Pleurotaceae • Genus : Pleurotus • Spesies : P. ostreatus
• Hypotesis 1. Gravity affect the growth and development
of Pleurotus ostreatus both in normal and almost zero gravity condition
2. Pleurotus ostreatus grows much faster under normal condition.
(the growth effect examined is on the morphology of Fungi)
Pleorotus ostreatus: widely cultivated mushroom with economic values in Indonesia
Results
• Gravity and Microgravity environtment didn’t affect the growth rate of Pleorotus ostreatus
• There is a difference in morphology between Pleorotus ostreatus under normal condition and microgravity environment
The experiment variables: 1. independent
variable : gravity: 2. Controlled
Microgravity Effect on the Growth of Mosses (Bryopsyda)
Bryopsyda has important role on the ecosystem: • Maintain soil moisture • provide humus to the soil • Indicator mineral deposits
Hypothesis: •The microgravity doesn’t affect the area covered by moss leaves
•The microgravity affects the distribution of moss leaves
Results
Distribution area of spores of moss
under microgravity is more equitable and more widely than distribution area of moss spore
under normal condition
Moss leaves need long time period (about 6 monts) for its growth and development so it can be seen by naked eye Such a relatively short experiment
time span, the observations done by microscope, to examine the spread of spores of moss leaves that already have sporangium
Effectivity of Rhizobium Japonicum on Soya Plants’ Growth that Treated
Under Microgravity Condition
Soybean is a one of source of protein, that is important especially in the food resources.
soybean seed placed on clinostat
Soybean plants with root nodules
Object: Soybean seeds (Glycine max L.), pure isolates bacterium Rhizobium japonicum Rhizobium is shaped
Gram-negative bacilli.
Hypothesis: Microgravity and inoculation of Rhizobium japonicum sp. affect the Soybean stem length and number of soybean leaves
Results
• soybean stem length and number of leaves t under microgravity /and
inoculation of Rhizobium japonicum sp. are higher than to soybean stem length and number of leaves in normal gravity conditions /and inoculations Rhizobium japonicum.
The Effect Of Microgravity And Electromagnetic Radiation To The Growth Of
Paddy Plant
Hypothesis: the development and growth of rice plants is affected by
microgravity and electromagnetic wave radiation.
a) How is the development of the paddy plant cells to microgravity
environment and radiation of electromagnetic waves?
b) How does the growth of the paddy plant cells to microgravity environment
and radiation of electromagnetic waves?

Root Cell Microscopy results: the structure of the root cells look different from normal.
Root Cell Microscopy results: The structure of root cells look different and tend to be smaller.
Results Cells Root Microscope: Normal root cell structure.
Results Microscopy Stem Cells: Root cell structure does not different
Results Microscopy Stem Cells: Root cell structure does not different
