Nine schools take part in mud­ball pro­gram

The Borneo Post (Sabah) - - HOME -

PE­NAM­PANG: Nine schools from Pe­nam­pang and Ka­payan at­tended the Ten­ta­tive Pro­gram of Mud Balls at Seko­lah Me­nen­gah Ke­bangsaan Ba­hang yes­ter­day.

The event was part of the ‘Ka­payanku In­dah’ pro­gram in­spired by Ka­payan as­sem­bly­woman Jan­nie Lasim­bang. The schools in­volved were SM High Kota Kinabalu, SM St Michael, SMK Ba­hang, SK Pe­nam­pang, SK Ke­payan, SJK (C) Shan Tao and SJK (C) Yue Min.

The pro­gram co-or­ga­nized by Maria Lasim­bang from Ki­vatu Na­ture Farm and Anne Lasim­bang from Guwas Kopo­si­zon Col­lege was also wit­nessed by Pe­nam­pang District Of­fi­cer Robert Stidi and Al­bert Min­ing who rep­re­sented Ex­ec­u­tive MDPG Of­fi­cer Datuk Philip Lasim­bang.

Ef­fec­tive fer­men­ta­tion bac­te­ria in mud­balls can help to de­com­pose sludge in pol­luted rivers or ditch channels. Ac­cu­mu­lated sludge (rot­ten or­ganic ma­te­rial) is in a state of oxy­gen de­fi­ciency, since there is lit­tle oxy­gen dis­solved in the wa­ter. In­side the sludge, harm­ful fer­men­ta­tion bac­te­ria (pu­tre­fac­tive bac­te­ria) pro­duce harm­ful gases such as meth­ane, am­mo­nia and hy­dro­gen sul­fide by de­com­pos­ing or­ganic mat­ter with­out oxy­gen.

When mud­balls are added to the wa­ter in this con­di­tion, they be­come em­bed­ded in the sur­face of the sludge and ef­fec­tive fer­men­ta­tion bac­te­ria con­tained in the mud­balls start to de­com­pose the sludge. At the same time, pho­totrophic bac­te­ria con­sume harm­ful gasses, so foul odors will be con­tained.

As fer­men­ta­tion de­com­po­si­tion pro­gresses, amino acids and sac­cha­rides are pro­duced. A por­tion of them dis­solves into the wa­ter and phy­to­plank­ton in­creases where there is sun­light, mak­ing use of this nu­tri­tion. Phy­to­plank­ton ac­tiv­i­ties will in­crease the oxy­gen in wa­ter, help­ing ox­ida­tive de­com­po­si­tion bac­te­ria, which re­quires oxy­gen to be more ac­tive. As a re­sult, de­com­po­si­tion of sludge is ac­cel­er­ated. Around mud­balls, zoo­plank­ton will in­crease, trans­form­ing sludge into de­tri­tus, an or­ganic sed­i­ment made of or­ganic mat­ter and mi­crobes, and the sludge will no longer be harm­ful.

De­tri­tus con­tain­ing bub­bles of car­bon diox­ide and oxy­gen etc., which are pro­duced by the ac­tiv­i­ties of mi­crobes, will rise to the sur­face. Some­times the rivers look pol­luted with these float­ing frag­ments of de­tri­tus. How­ever, this is due to the process of the de­com­po­si­tion of sludge and the pu­rifi­ca­tion of the rivers. As de­tri­tus breaks down into smaller seg­ments and flows along rivers, crea­tures which eat it, such as small fish, shrimp, crabs, and shell­fish, in­crease in num­ber. The more fish there are, the more birds will come, lead­ing to greater di­ver­sity in the ecosys­tem. The mi­crobes con­tained in de­tri­tus will im­prove the self­pu­rifi­ca­tion abil­ity of rivers by mak­ing the ecosys­tems of which they are a part richer and more vi­brant.
