Growth response larvae of giant tiger (Penaues monodon) on ethanol extract of Karamunting (Melastoma malabhatricum) that mixed in feed

Abstract

In fact, Karamunting is known to have a high cholesterol content, more specifically, lanosterol based on GCMS test. Lanosterol is the cholesterol that contained in plants, which assumed as a precursor of growth and reproduction hormone for in Crustaceae. This experiment consists of several steps: (1) Karamunting extraction, (2) GCMS test for Karamunting, (3) Making the feed by mixing the ethanol extract Karamunting for four weeks with concentration variable 0 (control), Variable 1: 1: 5, Variable 2: 1:2, Variable 3: 1:1, Variable 4: 2:1 dan Variable 5: 5: 1. (4) The measured parameters are water quality, growth in weight, growth in length, survival rate (5) Data analysis. Statistical analysis result of weight growth measurement indicates that ethanol extract of Karamunting gives a significant result to the larvae sample (P0.05). Statistical analysis result of length growth measurement at the end of the experiment indicates a significant difference between control and each variable (P0.05). Statistical analysis result of the survival rate at the end of the experiment indicates that the ethanol extract of Karamunting gives a significant result to the larvae sample (P0.05). Based on these results, it can be concluded that the ethanol extract of Karamunting on feed indicated an increase in the molting process the observation in weight and length indicates that the extract can stimulate molting acceleration rate.
