Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh paparan merkuri terhadap pertumbuhan P. expressa/cm3 dan mengetahui pengaruh kerapatan terhadap pertumbuhan P. expressa. Penelitian ini dilakukan di laboratorium pendidikan Biologi FKIP, Universitas Jambi pada bulan Maret – Mei 2020. Rancangan penelitian yang digunakan adalah Rancangn Acak Lengkap (RAL) faktorial dua faktor, A = Merkuri (terpapar merkuri dan tidak terpapar merkuri) dan faktor B = kerapatan P.expressa/10 L (kerapatan 10 individu/10 L, kerapatan 15 individu/10 L, dan kerapatan 20 individu/10 L) dengan 6 perlakuan yang terdiri A1B1, A1B2, A1B3, A2B1, A2B2, danA2B3. Setiap perlakuan dilakukan pengulangan sebanyak 4 kali. Data dianalisis menggunakan ANOVA dan apabila berpengaruh dilanjutkan dengan uji DMRT 5%. Hasil penelitian menunjukkan bahwa paparan merkuri dan kerapatan P. expressa berpengaruh nyata (P< 0,05) terhadap pertumbuhan. Rata-rata pertambahan panjang P. expressa pada faktor A terpapar merkuri 0,2 cm dan kontrol 0,46 cm, sedangkan rata-rata pertambahan panjang pada faktor B kerapatan 10 individu/10L 0,5 cm, 15 individu/10L dan 20 individu/10L 0,25 cm. Pada rata-rata pertambahan berat P. expressa pada faktor A terpapar merkuri 0,15 g dan kontrol 0,30 g, rata-rata pertambahan berat pada faktor B kerapatan 10 individu/10L 1,37 g, 15 individu/10L 0,42 g dan 20 individu/10L 0,08 g. Sementara itu, rata-rata laju pertumbuhan panjang P. expressa pada faktor A terpapar merkuri 0,12% dan kontrol 0,46%, dan rata-rata laju pertumbuhan panjang pada faktor B kerapatan 10 individu/10L 0,11 %, 15 individu/10L 0,09% dan 20 individu/10L 0,06%. Pada rata-rata laju pertumbuhan berat P. expressa pada faktor A terpapar merkuri 0,44% dan kontrol 0,5%, rata-rata laju pertumbuhan berat pada faktor B kerapatan 10 individu/10L 0,13%, 15 individu/10L 0,11% dan 20 individu/10L 0,11%. Dari hasil penelitian disimpulkan bahwa kerapatan dan paparan merkuri pada pertumbuhan P. expressa dapat menurunkan pertumbuhan dan membahayakan kehidupan P. expressa. This study aims to determine the effect of mercury exposure on the growth of P. expressa/cm3 and to determine the effect of density on the growth of P. expressa. This research was conducted at the Biology education laboratory, FKIP, Jambi University in March – May 2020. The research design used was a factorial Completely Randomized Design (CRD) with two factors, A = Mercury (exposed to mercury and not exposed to mercury) and factor B = density P .expressa/10 L (density 10 individuals/10 L, density 15 individuals/10 L, and density 20 individuals/10 L) with 6 treatments consisting of A1B1, A1B2, A1B3, A2B1, A2B2, and A2B3. Each treatment was repeated 4 times. The data were analyzed using ANOVA and if it had an effect, it was continued with the 5% DMRT test. The results showed that mercury exposure and density of P. expressa significantly (P<0.05) on growth. The average length increase of P. expressa in factor A exposed to mercury was 0.2 cm and control was 0.46 cm, while the average length increase in factor B was 10 individuals/10L 0.5 cm, 15 individuals/10L and 20 individuals /10L 0.25cm. On the average weight gain of P. expressa on factor A exposed to mercury 0.15 g and control 0.30 g, the average weight gain on factor B density 10 individuals/10L 1.37 g, 15 individuals/10L 0.42 g and 20 individuals/10L 0.08 g. Meanwhile, the average length growth rate of P. expressa on factor A exposed to mercury was 0.12% and control was 0.46%, and the average length growth rate for factor B was 10 individuals/10L 0.11%, 15 individuals. /10L 0.09% and 20 individuals/10L 0.06%. On the average weight growth rate of P. expressa on factor A exposed to mercury 0.44% and control 0.5%, the average weight growth rate on factor B density 10 individuals/10L 0.13%, 15 individuals/10L 0 .11% and 20 individuals/10L 0.11%. From the results of the study, it was concluded that the density and mercury exposure on the growth of P. expressa could reduce growth and endanger the life of P. expressa.
