Kualitas Air Pada Budidaya Ikan Patin (Pangasionodon Hypopthalmus) Dengan Manipulasi Fotoperiod Dan Sistem Akuaponik Kangkung (Ipomoea Aquatica)

---

ABSTRACT
Culturing Pangasius hypopthalmus in dark condition improved the fish
growth, however the water quality of the culture media was poor due to the lack
of phytoplankton that are able to consume organic material originated from
uneaten feed and metabolic waste. The use of plant in the aquaponics system may
be able to absorb the organic materials and thus improve the water quality. A
research aims to understand the effect of photoperiod manipulation and
aquaponics system using Ipomoea aquatica on the water quality of P.
hypopthalmus culture media was conducted on June-August 2021. There was a
CRD method with 2 factors, namely aquaponic, K (using Ipomoea aquatica)
and F (Filter) and also 2 levels of photoperiod factor, namely 24G (Dark) and N
(Natural photoperiod). The P. hypopthalmus fingerlings were reared in 100L
plastic container, 30 fishes/ container (around 8 cm TL and 4 gr BW), fed 2 times/
day using commercial fish feed pellets, ad libitum. Samplings were carried out 8
times, once/ week. Parameters observed were pH, temperature, DO, BOD5,
nitrate, phosphate and ammonia). Results shown that the use of aquaponics
system using I. aquatica improve the water quality in general. The best result was
obtained in Nat K (Natural photoperiod with Ipomoea) which shown temperature:
26.7-28.0◦C, pH:5.23-6.40, DO: 4.55-6.98 mg/L, BOD5: 3.50-9.33 mg/L, Nitrate:
0.193-0.547 mg/L, Phosphate: 0.022-0.039 mg/L dan Ammonia: 0.011-0.026
mg/L. While the worst was in 24GF, temperature 27.0-29.0, pH: 5.16-6.30, DO:
4.41-6.97 mg/L, BOD5 : 4.76-9.96 mg/L, Nitrate: 0.338-0.662 mg/L, Phosphate:
0.035-0.064 mg/L and Ammonia 0.020-0.077 mg/L. Data obtained indicate that
the use of I. aquatica in the aquaponics system is able to maintain the water
quality in the P. hypopthalmus rearing media.
Keywords: Catfish, rearing media, dark condition, organic materials.
