Abstract

Southeast Maluku area, seaweed is the livelihood of the community. However, in its cultivation there are some common obstacles that are often experienced. One of them is ice-ice disease caused by the presence of bacteria such as Aeromonas hydrophilla. Therefore, prevention that can be used as a solution is antibacterial. One of the natural ingredients that can be used as an antibacterial is seaweed, because it contains compounds that can inhibit bacterial growth. In general, the most common bioactive compounds found are flavonoids, phenols, and tannins. In addition to seaweed, mangrove plants also have compounds that can be antibacterial. The extract method used in this study is a simple extraction method that uses only one type of solvent, namely distilled water. And a comparison of concentrations between 100%, 80%, 60% and 40% was carried out. Then the inhibition zone test was carried out using the paper disc diffusion method, where the disc paper was dipped into each extract with different concentrations and placed in a petri dish that had been overgrown with bacteria. Measurement of the inhibition zone formed was carried out after the plates were incubated for 24 hours at 37oC. The measurement results show that both aquades extracts have medium to strong inhibitory power. The conclusion of this research is that aquades extract of seaweed and mangrove leaves has inhibitory power against Aeromonas hydrophilla bacteria.

Abstract

An analysis of the antibacterial ability of Vibrio sp. has been carried out from the ethanol extract of Ulva lactuca seaweed and its phytochemical study. Analysis of the antibacterial ability of Vibrio sp. using the disk diffusion method was the main thing carried out in this research, then the extract yield was calculated from the maceration process of Ulva lactuca seaweed, as well as phytochemical analysis to support the antibacterial ability of Ulva lactuca seaweed against the bacteria Vibrio sp. The results of the extraction of Ulva lactuca seaweed with ethanol solvent obtained a yield of 3.67%. The results showed a moderate antibacterial activity of Vibrio sp. from Ulva lactuca seaweed extract at a concentration of 100% was 17.3 mm. Weak antibacterial activity was at a concentration of 75% of 12.525 mm and extracts below a concentration of 75% did not have inhibitory power against Vibrio sp bacteria. Phytochemical studies of Ulva lactuca seaweed found secondary metabolite compounds in the form of alkaloids, flavonoids, steroids, tannins and saponins. Based on the results of this research, it is hoped that the antibacterial ability of Vibrio sp. can be further investigated from ethanol extract of Ulva lactuca seaweed in vivo.

Abstract

The activated carbon made in this study is activated carbon in the form of powder and granules (a mixture of the two) by a chemical activation process using calcium oxide (CaO). The characterization of activated carbon refers to the Indonesian National Standard 06-3730-1995 concerning technical activated carbon with the indicators tested being moisture content, volatile matter content, total ash content, bound carbon content and iodine adsorption capacity. Based on research on the characterization of activated carbon, nutmeg shells have a moisture content of 0.6979 %, volatile matter content of 3.8781%, total ash content of 8.7323%, bound carbon content of 87.3896 % and iodine adsorption capacity of 325. 0694 mg/g. Iodine adsorption capacity aims to determine the adsorption capacity of activated carbon. Based on the technical quality standard of activated carbon regarding iodine adsorption capacity stipulated by SNI 06-3730-1995, researchers can explain that the pore capacity of nutmeg shell activated carbon is very good for use as an adsorbent. The important use of activated carbon in nutmeg shells as an adsorbent is expected to be utilized for water purification from bacteria, absorption of inorganic materials dissolved in water and cosmetic base ingredients.
