Laju Pertumbuhan Rumput Laut Kappaphycus alvarezii Varietas Hijau dan Coklat pada Metode Budidaya yang Berbeda

Abstract

This research is about the growth rate of green and brown Kappaphycus alvarezii seaweed in different cultivation methods. This study aims to compare the growth of Kappaphycus alvarezii green and brown varieties and determine the appropriate cultivation method for waters in the Riau Islands. This research was conducted from 27 May 2021 to 11 July 2021 for 45 days in Berakit Village, Teluk Sebong District, Bintan Regency, Riau Islands Province. In this study, there were two variations, namely the green variety and the brown variety with a Randomized Block Design (RAK) with each variation having 3 treatments and 3 replications. The parameters measured were absolute weight growth, specific growth rate, survival and water quality. Data analysis used a two-way ANOVA test of variance and continued with the Tukey test. The results showed that the highest seaweed growth was found in green varieties with the best cultivation method being floating rafts.
