Abstract

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.

Abstract

Research on the diversity of invertebrate epifaunas associating with mangroves in the Balangdatu village of Tanakeke regency, Takalar district, South Sulawesi, has been conducted from September to December 2016. The objective of this research was to know the diversity of invertebrate epifaunas associating with mangrove in Balangdatu Village of Tanakeke Islands. Sample collection was done by using explorative quantitatively plot methods with size 2 x 2 m, applied at three different stations. Data analysis includes calculation of Absolute density, Uniformity Index (Shannon-wiener), Dominance Index, and Distribution Index. The results showed that there were 13 species of epi fauna of 9 tribes, namely Littoraria sp 1, Cerithidea cingulata, Littoraria sp 2, Littoraria pallescens, Episesarma sp, Saccostrea cucullata, Pagurus sp, Terebralia sulcata, Cerithidea sp, Nerita planospira, Nisto histrio, Littoraria scabra, and Cassidula vespertilionis. The highest density was found in Littoraria scabra with a density of 0.72 ind/m2. Diversity indices are low which indicate depressed environmental conditions. Distribution Index values across stations <1 indicating that the pattern of individual dispersion tends to be uniform.

Abstract

Chitosan can be obtained from chitin isolated from shrimp waste through the process of deacetylation of chitin. Chitosan can be used as a patch base material because of its biocompatibility and biodegradability, and has antibacterial activity. The combination of Chitosan and Aloe vera extracts may be useful in patch dosage forms as wound dressings that have antiinfective activity. The research methods was laboratory experimental which consists of : chitosan was obtained from shell waste sequentially by deproteinisation, demineralisation, and deacetylation processes, and analyzed its characteristic, respectivel; Aloe vera gel was extraction by maceration methods using ethanol as solvent; patches were formulated using 2 % chitosan in 1.5 % glacial acetic acid,  1.6 %  Aloe vera extracts and 10 % glycerin and evaluated its physical propoperties,  skin iritation test, and antibacterial test against S.aureus. The results showed that percentage yield of chitosan was 32.67%, with characteristics; Its viscosity 93.33 cps, pH 4, 30 % deacetylation degree.  Percentage yield of Aloe vera  extract was 22.73%, containing acemannan, and had antibacterial activity against S.aureus.  The result of patch evaluation showed that the thickness of patch was 0.45 mm, 114 times folding endurance, moisture uptake of 45.03%, moisture content of 23.64%, safe to use, and  diameter of inhibition zone was 6.39 mm against S.aureus. So, combination of Aloe vera and Chitosan from shrimp shell as patch may use as antiinfection wound healing.  Keywords : Aloe vera L.; chitosan; wound dressing; patch; shrimp shell waste

Abstract

IntroductionEarthworms (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. MethodsEarthworms 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.ResultsThe 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.ConclusionsThe highest percentage of entrapment efficiency of earthworms extract ethosome was 72.58%.Keywords : ethosome, ethanol concentration , entrapment efficiency, Lumbricus rubellus.

Abstract

Algae Spirogyra peipingensis is a group of green algae from the order Zygnematales. Spirogyra algae serves as a bioremediation agent. In addition Spirogyra algae has great potential in reducing toxin levels in cigarette smoke. Because the biomass of alga Spirogyra has an irregular shaped surface texture and consists of amino acid, amide, carboxylic, hydroxyl, and carbonyl group that can bind various heavy metals and other harmful compounds. Alga Spirogyra peipingensis samples used are algae from Bone, South Sulawesi. Prior to the trial, the first pretreatment and processed to become powder. Algae powder was then applied to cigarette filters and tested on several respondents. Results showed that there was a significant decrease  tar, nicotine and carbon monoxide levels in cigarette smoke by using Spirogyra peipingensis algae but the most significant decrease of carbon monoxide, while tar and nicotine decreased even though not as high as carbon monoxide.
