ABSTRACT
Peat water has unfavorable physical properties for fishery activities such as high
TDS, TSS and turbidity values so that the utilization and management of
peatlands is still less than optimal. Efforts to improve the physical parameters of
peat water can be done by utilizing the aquatic plant Azolla microphylla as a
biofilter that can absorb organic matter. This research was carried out in August-
September 2021 at the Experimental Pool and Marine Chemistry Laboratory,
Faculty of Fisheries and Marine Affairs, Riau University. The purpose of this
study was to determine the effect of Azolla microphylla biomass and to obtain the
best biomass in improving the physical parameters of peat water in Siamese
catfish (Pangasianodon hypophthalmus) rearing media. This research method
used a 1-factor completely randomized design (CRD) with 4 treatment levels and
3 replications (Sudjana, 1991). The parameters measured in this study were TSS
using the gravimetric measurement method, TDS using electrometry, turbidity
using the nephelometric measurement method, fish length using the formula
according to Zonneveld (1991) and feed conversion using the formula according
to Effendie (1997). The treatments in this study were the administration of
different Azolla microphylla biomass, namely Am0 (Control), Am1 (20g/m2),
Am2 (40g/m2) and Am3 (60g/m2). The results showed that the best treatment was
by giving 60 g/m2 of biomass because it was able to improve the physical
parameters of peat water for catfish rearing media such as reducing TSS by 68.5%
(83.67 mg/l – 26.33 mg/l), TDS of 37.65% (131 mg/l – 81.67 mg/l), turbidity of
70.5% (52.51 NTU – 15.47 NTU) and brightness from 10,17 cm to 20,75 cm. The
absolute length of the fish was 2.50 cm and the feed conversion was 1.14. The
Student-Newman-Keuls test showed that azolla had an effect on reducing the
levels of TSS, TDS and turbidity of peat water in Siamese catfish rearing media.
