Purpose of this research is to exploit the shell and palm fiber become the active charcoal, by looking at the influence of the ratio mixture composition and effect of activator. this Active charcoal application as adsorbent to the liquid waste of crude palm oil. Initial treatment, shells and palm fiber dried first at a temperature of 1200C and carbonized. charcoal mix shell and palm fiber activation chemically with a solution of H2SO4 by way of immersed in the solution for 24 hours. The best quality activated charcoal obtained from the comparison of the 75% shell, 25% palm fiber with activator H2SO4 that has a yield of 95.94%, 4.9% moisture content, ash content 6.13%, iodine number 916.594 mg / g. Activated charcoal mixture palm shell and palm fiber can be used as adsorbent liquid waste CPO, which is indicated by a decline in these parameters in the waste water contaminants in CPO, which is a 7.49 pH of 9, TSS of 660 ppm to 325 ppm,COD becomes 237,12 mg/L from1577.60 mg/L

UJI AKTIVITAS ANTIOKSIDAN DAN FORMULASI SEDIAAN MASKER PEEL-OFF MINYAK DAGING BUAH ALPUKAT (PERSEA AMERICANA MILL)

ABSTRAKAlpukat (Persea americana Mill) merupakan buah yang kaya akan vitamin A, vitamin C, vitamin E serta minyak alami sehingga menjadikan buah alpukat salah satu buah dengan kandungan antioksidan yang tinggi. Masker peel-off adalah salah satu bentuk kosmetik topikal yang dapat memberikan manfaat bagi kulit. Penelitian ini bertujuan untuk mengetahui aktivitas antioksidan minyak daging buah alpukat dan memformulasikan minyak daging buah alpukat dalam sediaan gel masker peel-off. Pengujian aktivitas antioksidan minyak daging buah alpukat dilakukan dengan metode DPPH (1,1-diphenyl-2-picrylhydrazyl) dan diperoleh nilai IC50 sebesar 116,4 ppm. Berdasarkan hasil tersebut dilakukan formulasi gel peel-off dengan menggunakan polivinil alkohol (PVA) sebagai basis. Gel yang dihasilkan bening dan berbentuk kental. Hasil evaluasi terhadap sediaan menunjukkan bahwa tidak terjadi perubahan warna, bentuk dan bau selama penyimpanan pada suhu 4?C dan 40?C. pH sediaan dan waktu kering sediaan gel memenuhi kriteria sediaan topikal. Nilai viskositas dan daya sebar sediaan tidak memenuhi kriteria sediaan gel yang baik. Hasil uji sifat mekanik sediaan menunjukkan bahwa formula P2 memiliki nilai paling baik pada kekuatan tarik dan elongasi sehingga diperoleh film gel yang tidak mudah putus.Kata kunci: minyak daging alpukat, antioksidan, gel masker peel-off ABSTRACTAvocado (Persea Americana Mill) is one of strong antioxidant fruits which contains high vitamins A, C, E, and avocado oil. Peel-off mask is one of cosmetic products that gives benefit to the skin. This study aimed to investigate the activity of avocado flesh oil antioxidant and formulate the flesh oil of avocado in a peel-off mask product. The experiment of avocado flesh oil antioxidant activity used DPPH (1,1-diphenyl-2-picrylhydrazyl) method and found the value of IC50 is 116,4 ppm. Based on the previous result, the researcher formulated peel-off gel by using polivinil alcohol (PVA) as a basis. The gel poduced was transparently and thick.
