Abstract

Budidaya rumput laut banyak dilakukan untuk memenuhi dan meningkatkan produksinya, namun masih banyak kendala, sehingga hasil produksinya belum stabil. Hal ini dapat dilihat dengan pemberian nutrien yang diharapkan akan meningkatkan pertumbuhannya. Tujuan dari penelitian untuk mengetahui pertumbuhan dan kemampuan absorpsi Gracilaria sp. pada media yang mengandung Cu dengan konsentrasi yang berbeda. Metode yang digunakan adalah metode eksperimental laboratoris dengan Rancangan Acak Lengkap (RAL). Perlakuan penambahan konsentrasi Cu pada media pemeliharaan yang terdiri dari 4 tingkat yaitu kontrol (0,036 ppm, sesuai dengan konsentrasi Cu pada air laut), 0.5 ppm, 5 ppm, dan 50 ppm dengan 3 pengulangan. Hasil memperlihatkan bahwa penambahan Cu dengan konsentrasi yang berbeda  memiliki pengaruh nyata (p < 0,05) terhadap pertumbuhan dan kemampuan absorpsi pada Gracilaria sp. Pertumbuhan Gracilaria sp. tertinggi dicapai pada perlakuan A (kontrol) dengan pertambahan berat sebesar 25,34 g dan laju petumbuhan spesifik (SGR) sebesar 0,43%. Nilai pertumbuhan mutlak dan laju pertumbuhan spesifik (SGR) yang didapatkan pada perlakuan B (0,5 ppm) sebesar  -80,37 g dan -1,84% per hari, perlakuan C (5 ppm) sebesar -85,19 g dan -2,02% per hari, dan perlakuan D (50 ppm) sebesar -99,19 g dan -2,47% per hari. Semakin tinggi konsentrasi Cu yang diberikan maka pertumbuhan Gracilaria sp. akan semakin rendah. Seaweed cultivation is done to meet and improve its production, but there are still many obstacles, so its results are not yet stable. This can be seen with the awarding of the nutrients that will hopefully increase its growth. The goal of the research is to know the growth and absorption ability of Gracilaria SP. in medium containing different concentrations of Cu with. The method used is the method of experimental design of randomized Complete laboratories (RAL). Addition of Cu concentration on treatment of media maintenance which consists of 4 levels, namely control (0.036 ppm, according to the concentration of Cu in sea water), 0.5 ppm, 5 ppm and 50 ppm, with three repetitions. The results showed that the addition of Cu with a different concentration of real influence (p < 0.05) towards growth and the ability of absorption on Gracilaria sp. Highest growth of Gracilaria sp. was achieved on A treatment (control) and the increase of the weight of 25.34 g and specific growth rate (SGR) of 0.43%. The absolute growth rate and specific growth rate (SGR) obtained at the treatment B (0.5 ppm) of -80.37g and-1.84% per day, treatment C (5 ppm) of -85.19 g and -2.02% per day, and treatment D (50 ppm) for -99.19 g and -2.47% per day. The higher the concentration of Cu given, then the growth of Gracilaria sp. will be even lower.
