MANAJEMEN KUALITAS AIR MEDIA BUDIDAYA IKAN LELE SANGKURIANG (CLARIAS GARIEPINUS) DENGAN TEKNIK PROBIOTIK PADA KOLAM TERPAL DI DESA VOKASI REKSOSARI, KECAMATAN SURUH, KABUPATEN SEMARANG
ABSTRACT: Cultivation of
Sangkuriang catfish (Clarias gariepinus) intensively can result in the decrease
of quality of cultivation media water, among others the decrease of dissolved oxygen
content and the increase of waste content especially organic nitrogen. The
technology has been implemented to manage the activities of Sangkuriang catfish
cultivation in Reksosari Vocational Sub-District, Suruh District, Semarang
Regency using probiotic in cultivation media. This study aimed to compare the
growth of Sangkuriang catfish raised by using probiotic and non-probiotic
system cultivation media. The test animals used in this study were Sangkuriang
catfish seedlings of 10 days for 500 seedlings raised for 30 days. The
observation was conducted on day-0, day-15, and day-30. The observed parameters
of growth were water temperature, dissolved oxygen, pH, and ammonia. The study
result indicated that there was a difference in length and weight increase of
Sangkuriang catfish in probiotic and non-probiotic application cultivation
media. Although the increase of growth was not significant, but it could give
illustration that Sangkuriang catfish raised using probiotic application
experienced a better growth. It indicated that the feed given and the raising
media could support the growth of Sangkuriang catfish. The raising media
implementing probiotic technique showed a better and relatively ideal condition
for Sangkuriang catfish.
