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).

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.

Experiment time : Juli - October 2015. During experiment, progress report : 2

 

Final Presentation :

    

    

   

Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentation

  • Mealworms has complete metamorphosis stage
  • Mealworms is an object that relatively easy to find, adaptivable and useable as decomposer

 

Hypothesis : There is the effect of microgravity on metamorphosis time and morphology of mealworms (Tenebrio molitor)

Results :

31 days Observations

  • The object 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)
 
  

  • Kingdom : Fungi
  • Divisi : Basidiomycota
  • Kelas : Agaricomycetes
  • Ordo : Agaricales
  • Famili : Pleurotaceae
  • Genus : Pleurotus
Pleorotus ostreatus : widely cultivated mushroom with economic values in indonesia  

Hyphothesis : 

  • Gravity affect the growth and development of Pleurotus Ostreatus both in normal and almost zero gravity condition
  • Pleurotus ostreatus grows much faster under normal condition.
the growth effect examined is on the morphology of fungi

 

The experiment variables :

  1. Independent variable : gravity
  2. Controlled variables : baglog quality, temperature, pH, water, nutrition, light, humidity
  3. Dependent variables : morphology differences of Pleurotus ostreatus under normal gravity and microgravity environment.

 

Results :

  • Gravity and microgravity didn't affect the growth rate of Pleorotus ostreatus
  • There is a difference in morphology between Pleorotus ostreatus under normal condition and mocrogravity environtment

 

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 mocrogravity affects the distribution of moss leaves

Moss leaves need long tipe period (about 6 months) for its growth and development so it can 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

 

Result : Distribution are of spores of moss under microgravity is more equitable and more widely than distribution area of moss spore under normal condition.

 

Soybean is a one of source of protein, that is important especially in the food resources.

Hypothesis : Microgravity and inoculation of Rhizobium Japonicum sp. affect the soybean stem length and number of soybean leaves.

Object : Soybean seeds (Glycine max L.) pure isolates bacterium Rhizobium Japonicum 

Soybean plants with root nodules Rhizobium is shaped Gram-negative bacilli Soybean seed placed on clinostat

 

Result : 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 leaver in normal gravity conditions /and inoculations Rhizobium Japonicum

Hypothesis :

the development and growth of rice plant is affected by microgravity and electromagnetic wave radiation.

  1. How is the development of the paddy plant cells to microgravity environtment and radiation of electromagnetic waves?
  2. How does the growth of the paddy plant cells to microgravity environtment and radiation of electromagnetic waves?

 

Results :

A : Rice plants treated with electromagnetic waves and under microgravity condition B : Rice plants under microgravity condition C : Rice plants under normal condition
Grow Faster Grow slower Grow normal
Kemotropisme growth (the root moving towards the nutrient) Kemotropisme growth (the root moving towards the nutrient) Geotropisme growth (roots move down attracted by gravity)

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 cells structure does not different Results microscopy stem cells : Root cells structure does not different Results microscopy stem cells : Root cell structure does not different
