The existence of macrozoobenthos in an ecosystem is closely related to the conditions of the surrounding environment. This research aimed to examine the physical chemical condition of aquatic environment and macrozoobenthos community structure in the coastal waters of Marsergu Island. This research was conducted in July and December 2016 in 3 stations. The data were collected by using sampling technique to measure the environmental factors (temperature, salinity, pH, and dissolved oxygen of seawater) and enumeration of gastropod species with in-situ. The results of this research showed that macrozoobenthos in the coastal waters of Marsegu Island consisted of 2 Phylum, namely Molusca and Echinoderms, that is, gastropod with 18 species, bivalvia with 5 species, and echinoderms with 17 species. Echinoderms was the dominant macrozoobentos with a percentage of 45%, followed by gastropods 42%, and bivalvia 13%. This suggests that echinoderms and gastropods are the main components that make up the macrozoobenthos community structure in the coastal waters of Marsegu Island. The results of the calculation of the diversity index of macrozoobenthos in the three research stations showed the highest score was station 1 as much as 3.56, station 2 as much as 3.52 and the lowest was station 3 as much as 2.07.

Introduction Earthworms (Lumbricus rubellus) extract is known to contain bioactive protein as antibacterial compounds. One of the disadvantages of polar compounds is slow penetration into the skin layers which can be solved by formulating it in the form of ethosomal drug delivery system. The aims of this research was to get information about ethanol concentration that can give the highest entrapment efficiency of the ethosome. Methods Earthworms powder was macerated using 50% ethanol for 3 days. The extract was formulated into ethosome with variation of ethanol concentration that are 20%, 30%, 40%, and 50%, respectively. The measurement of entrapment efficiency was conducted by measuring the amount of active protein of earthworms extract that was entrapped in ethosome vesicles using spectrophotometer UV-Visible. Results The results showed that the highest entrapment efficiency was 72.58 % performed by formula which was made with 0.5 % extract, 2 % soy lecithin and 50 % ethanol. Conclusions The highest percentage of entrapment efficiency of earthworms extract ethosome was 72.58%. Keywords : ethosome, ethanol concentration , entrapment efficiency, Lumbricus rubellus.

Algae Spyrogyra hyalina is one species of fresh water algae that is very easy to find in Indonesia. This species of algae known to have a lot of potential, which until now unknown. One potential that tried to explore in this research is the ability of these algae for decreasing the level of salt water salinity into fresh water. This research is an experiment with a completely randomized design (CRD), three treatments and three replications. Testing is done by performing algae arbsorbtion using three forms (powder, granule, and paper) with different biomass (1 g, 2 g, and 4gr). Preparations then coupled into a transparent pipe. The results showed the real effect of the decreased levels of salinity brine through the circuit. Filter with the powder forms with 4gr biomass has the highest salinity level reduction of 15% o, then the dosage form of granules with biomass 4gr with decreased 5.23% o and the third dosage form of paper with 1 gram of biomass with a decrease of 4.23% o. Forms with other biomass have a decrease in the salinity level of not more than 4% o. Preparations with powder form and 4gr biomass can be used to reduce the salinity level in the salt water.

This species of algae known to have a lot of potential, which until now unknown. One potential that tried to explore in this research is the ability of these algae for decreasing the level of salt water salinity into fresh water. This research is an experiment with a completely randomized design (CRD), three treatments and three replications. Testing is done by performing algae arbsorbtion using three forms (powder, granule, and paper) with different biomass (1 g, 2 g, and 4gr). Preparations then coupled into a transparent pipe. The results showed the real effect of the decreased levels of salinity brine through the circuit. Filter with the powder forms with 4gr biomass has the highest salinity level reduction of 15% o, then the dosage form of granules with biomass 4gr with decreased 5.23% o and the third dosage form of paper with 1 gram of biomass with a decrease of 4.23% o. Forms with other biomass have a decrease in the salinity level of not more than 4% o. Preparations with powder form and 4gr biomass can be used to reduce the salinity level in the salt water.","PeriodicalId":14981,"journal":{"name":"Journal of Applied Biology & Biotechnology","volume":"66 1","pages":"9-13"},"PeriodicalIF":0.0,"publicationDate":"2017-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82192148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
