Moringa oleifera

Background

Geographical FloodInfrastructure damage

Human Error

Still consumed for surviving

ObjectiveTo describe thorough understanding of Moringa oleifera as a disinfectant and water purifier

BenefitProvides deeper understanding for future research on effectiveness of Moringa oleifera

• Moringa oleifera or known as “Kelor”, from Genus Moringa Adans. – moringa and Species Moringa oleifera Lam. – horseradishtree

• 10 or 12 m in height• The leaves are feathery and green in color in upper surface and paler with

hairless in other surface• Grows well in lowland area (up to 1200m) of tropical area• Contains many carbohydrate, vitamins, proteins, minerals and also some

essential molecules (antibacterial properties)

• Nutritious food• Disinfectant and water purifier• Medical uses, etc.

Back

Definition• a disease caused by ingestion of water contaminated by human or

animal excrement, which contain pathogenic microorganisms

Epidemiology• Mostly in areas affected by natural disasters such as earthquakes,

tsunami, floods and cyclones, which can spread through contaminated water

Etiology• Bacteria, viruses, and protozoa (mostly bacteria, e.g. Vibrio cholerae,

Salmonella typhi, E. coli)

DISCUSSION

Disinfectant Advantages Disadvantages

Chlorine Very effective for disinfectant Well-known and most widely used

method for water treatment

Influence the pH value of the water Increase the soluble residues and increase

volume and metal content of the sludge Too reactive Has toxic effect as a chemical substance It combines with inorganic material in

water to form chloride saltsMoringa oleifera Friendly

Widely spread, esp. in tropical countries Available and easy to store product Allows water treatment without external

dependence (pH) Has no noxious effect on human health The processing does not modify the pH of

the water It does not alter the water taste (unless a

very high dosage is added)

purified water might still carry some (very few) pathogenic germs or microorganisms

Not too effective as chemical substances Not common used in Indonesia

ConclusionComparing to Chlorine, a chemical substance, that gives side effects, Moringa oleifera is an organic substance that much less harmful, cheap, easily found and more environmentally friendly

Further research is highly recommended in Indonesia either from government or institution, so that application of Moringa oleifera can give true benefits and will be widely used by people.
