THE FORMULATION OF PEEL-OFF MASK FROM THE ETHANOL EXTRACT OF BILIMBI LEAVES (Averrhoa blimbi L.) AS ANTI-ACNE TREATMENT

This research aims to formulate and assess the efficacy of the peel-off mask as an anti-acne of ethanol extract from bilimbi leaves (Averrhoa bilimbi L.). The method used was an experiment, evaluating the extract through the inhibition test of Staphylococcus epidermis bacteria with the paper disk diffusion method. The peel-off mask formulation added the extract with a concentration of 7% (F1), 9% (F2), 11% (F3), and without using extract (F0). The Peel-off mask preparation testing includes the detection of scents, colours, irritation checks, and the determination of peel-off anti-acne mask efficacy. This study was carried out at Akafarma of Banda Aceh and the Chemistry laboratory of FKIP Unsyiah. The findings of the inhibition zone for Staphylococcus epidermis bacteria at extract concentrations of 100%, 75%, 50% and 25% were 15 mm, 12 mm, 11 mm and 10 mm, respectively. The four peel-off mask formulas were gel, homogeneous, brown, with the distinctive scent of bilimbi leaves, and did not irritate the volunteers’ skin. The average decline in acne before and after using the mask for any formula (F0, FI, FII, and FIII) was 19.64%, 22.63%, 28.75% and 50%, respectively. The peel-off mask of ethanol extract of bilimbi leaves (Averrhoa bilimbi L.) is effective as an anti-acne treatment.

POTENSI BEBERAPA JENIS RUMPUT LAUT DI ACEH (STUDI KASUS: SKRINING FITOKIMIA DAN AKTIVITAS ANTIOKSIDAN)

One of the sea potentials in Aceh is seaweed. Seaweed contains secondary metabolites and antioxidants that are very well consumed because it can act as an antidote/protector from the free radicals. This study aimed to determine the secondary metabolite content and antioxidant activity of seaweed in Aceh.The seaweed that has been macerated then screened for phytochemicals and tested for antioxidant activity by using the DPPH method. The seaweed species found were Gracillaria verrucosa, Sargassum sp., and Chaetomorpha antennina. The results of this study indicated that Gracillaria verrucosa, Sargassum sp., and Chaetomorpha antennina seaweeds were contained by alkaloids and steroids. Flavonoid and saponins were only detected in the types of seaweed Gracillaria verrucosa and Sargassum sp. It was also found that the higher the concentration of the extract, the higher the percentage of IC50 against free radicals. The Sargassum sp. has a stable percentage of inhibition at a 2-10 ppm concentration, so it is recommended in this study to be considered cultivated in Aceh.

PURIFICATION OF DUG WELL WATER FROM Escherichia coli BY USING CARBON OF RICE HUSK

Clean water is one of the human's main needs. Dug well water in Tombang, used for various needs. However, the dug well water has been polluted by E. Coli bacteria which is suspected to be due to the disposal of rubbish and waste carelessly and also the distance of latrines and dug wells that are very close together. Therefore it is important to do water purification using agricultural waste that is not utilized. The analysis showed that the purification of dug well water in Tombang with rice husk charcoal had reduced E. Coli bacteria by 55.6% with MPN pattern 1-0-3 so that the MPN value was 11/100 mL of sample.
