ABSTRAK
Penelitian bertujuaan untuk mengetahui hubungan antara bioakumulasi logam merkuri (Hg) dengan kelangsungan hidup ikan tombro (Cyprinus carpio, L.) yang dipelihara di kolam fakultatif 1 IPAL Sewon, Bantul, Yogyakarta.

Sampel penelitian adalah ikan tombro umur satu bulan, sebanyak 150 ekor. Parameter kualitas air limbah di kolam fakultatif 1 IPAL Sewon sebagai variabel penentu berupa kandungan Hg, pH, suhu, DO, COD, BOD, dan turbiditas, sedangkan kelangsungan hidup ikan tombro selama dua bulan pemeliharaan merupakan variabel tergayut. Analisis regresi ganda untuk mengetahui hubungan antara kandungan Hg dan kualitas perairan kolam fakultatif 1 IPAL Sewon terhadap kelangsungan hidup ikan tombro. Analisis varian digunakan untuk mengetahui apakah terdapat perbedaan antara kelangsungan hidup ikan tombro yang dipelihara di kolam fakultatif 1 IPAL Sewon dengan di kolam kontrol (di Anial House Biologi, FMIPA, UNY).

Hasil analisis regresi ganda menunjukkan bahwa ada hubungan antara kualitas air dengan kelangsungan hidup ikan tombro uji, selama dua bulan pemeliharaan (p < 0,05). Berdasarkan hasil analisis varian terdapat perbedaan nyata antara kelangsungan hidup ikan tombro di kolam fakultatif 1 IPAL Sewon dengan di kolam kontrol (p<0,01).

ABSTRACT


This research aims at determining the relationship between bioaccumulation of mercury (Hg) metal in the viability of gold fish (Cyprinus carpio, L.) maintained in a facultative pond 1 at Sewon Wastewater Treatment Plant (IPAL) - Bantul, Yogyakarta.

The research samples were 150 one-month-old gold fishes. Waste water quality parameters in the facultative pond 1 of IPAL of Sewon as determinant variables were in the forms of the content of Hg, pH, temperature, DO, COD, BOD, and turbidity, while the viability of the gold fishes during the two-month maintenance was the dependent variable. Multiple regression analysis was done to determine the relationship between Hg content and the water quality of the facultative pond 1 of IPAL of Sewon on the viability of the gold fishes. Analysis of variance was used to determine if there was any difference between the viability of gold fishes maintained in the facultative pond 1 of IPAL of Sewon and ones maintained in a control pond (in Biology Animal House of FMIPA, UNY).



Results of the multiple regression analysis showed that there was a relationship between water quality and the viability of tested gold fishes, during two months of the maintenance (p <0.05). Based on the results of the variance analysis, there were significant differences between the viability of gold fishes in the facultative pond 1 of IPAL of Sewon and ones in the control pond (p <0.01).
Key words: bioaccumulation, viability, gold fishes, IPAL
