NATRIUM CHLORIDE AND CUPRI SULFATE AGAINST GROWTH OF CYANOPHYTE ALGAE ISOLATION FROM BRICK TEMPLE
Bali is popular as a thousand temples island because of the many temples in Bali. The main
construction of the temple in Bali-based such as brick, sandstone and red rock. Prevention
decomposition of building materials can be done by way of physics and chemistry. One of
control to this growth of microorganism is use NaCl and cuprisulfate (CuSO4). The research
about the effect of salt (NaCl) and cupri sulphate (CuSO4) against the growth of Cyanophyte
algae aims to compare the various concentration between salt and cupri sulphate in inhibiting
the growth of Cyanophyte algae isolated from brick temple building in the village of Tejakula
Buleleng. This experimental research used randomized control group design. The procedure of
this research is started with data collection, observation of objects by counting the number of
algae growth in medium which given various concentration of salt and cupri sulphate, 0%, 5%,
10%, 15%, 20%, and 25%. Univariate analysis showed the influence concentration (5%, 10%,
15%, 20% and 25%) against inhibition growth of algae with 2 types treatment is NaCl and
CuSO4, interaction between treatment showed less from 0.05 is 0.000 (significant different).
The result showed that treatment with salt and cupri sulphate in different concentration
inhibiting the growth of Cyanophyte algae. This is evidenced by the existence of barrier to the
growth of algae in salt medium is better than cupri sulphate, except in 10% concentration.
Cyanophyta algae isolated from brick temple building materials in Tejakula Village Buleleng also
grow well on aquadest medium.
