Abstract

Kulit pisang merupakan limbah organik yang berpotensi tinggi sebagai sumber kalium alami untuk pembuatan pupuk ramah lingkungan. Penelitian ini bertujuan untuk mengetahui pengaruh jenis kulit pisang terhadap kandungan kalium yang dihasilkan pada proses sintesis pupuk nano kalium sulfat (K₂SO₄). Bahan yang digunakan terdiri atas tiga jenis kulit pisang, yaitu kulit pisang kepok, pisang raja, dan pisang raja nangka. Masing-masing sampel diekstraksi dan disintesis menjadi nano K₂SO₄ melalui proses presipitasi, kemudian dikarakterisasi menggunakan X-Ray Fluorescence (XRF) untuk menentukan komposisi unsur, serta didukung dengan analisis Scanning Electron Microscopy (SEM) untuk mengamati morfologi partikel. Hasil analisa XRF menunjukkan bahwa kulit pisang kepok memiliki kandungan kalium tertinggi sebesar 50,6% dan sulfur sebesar 49%, dengan kadar pengotor logam yang rendah (Fe 0,07% dan Cu 0,2%). Kulit pisang raja dan pisang raja nangka menunjukkan kandungan kalium masing-masing 29,1% dan 37%, disertai adanya unsur molibdenum (Mo) yang cukup tinggi. Berdasarkan hasil tersebut, dapat disimpulkan bahwa jenis kulit pisang kepok menghasilkan pupuk nano kalium sulfat dengan kandungan kalium paling tinggi dan kemurnian terbaik, sehingga paling potensial digunakan sebagai bahan dasar pembuatan pupuk nano berbasis K₂SO₄.

Abstract

ABSTRACT Herbal medicine is used for generations because of its safety and free from adverse side effects, but the healing process takes a long time. This is the background of herbal medicine manufacturers to improve their performance by adding dexamethasone compounds. This compound is a synthesis of corticosteroid hormones whose use must be under the supervision of a doctor because it has side effects of cardiovascular disease, Cushing's syndrome, osteoporosis, hypertension, gastrointestinal ulcers, infections, and cataracts. The presence of this compound can be detected using the Thin Layer Chromatography method by comparing the Rf value of the sample with the standard solution of dexamethasone. The eluents used are methanol, ethyl acetate, and toluene with a ratio of 1:45:55. This method was used to detect dexamethasone content in six samples of packaged herbs circulating in the Mojokerto region, East Java province. Of the six samples analyzed, five of them showed positive results, namely samples A, B, C, D and F with a difference in the Rf value of the sample and standard of each 0.01; 0.01; 0.00; 0.00; and 0.02. Sample E does not contain dexamethasone indicated by the difference in the sample's Rf value against the 0.5 standard. Keywords: Herbal medicine, herbal packaging, dexamethasone, corticosteroids, Thin Layer Chromatography (TLC).

Abstract

Ganoderma lucidum, lingzhi or reishi mushroom is a plant containing secondary metabolites that are of wide interest due to their biological activities. Among them the most important is its Antioxidant activity. Free radicals are potentially damaging byproducts of metabolism. Antioxidants neutralize free radicals in the body and thus help to protect against disease (source) The study was conducted to determine the antioxidant effect, as measured by DPPH radicals scavenging capability of hand and body lotions with lingzhi mushroom extract included. Maceration was used to extract lingzhi and the yield of extraction is 14.17% The results of the preliminary phytochemical analysis showed that lingzhi has contained compounds related to flavonoid, phenolat, triterpenoid and steroid. The antioxidant activity assay further confirmed the results as lingzhi extract showed very high antioxidant (46.9 ppm) potential when tested against DPPH scavenging by abrogating red purple color at 517nm table(Table.). In addition, the incorporation of lingzhi extract with hand and body lotion also increased antioxidant activity, where 0.75% lingzhi extract was found have to produce most effective DPPH inhibition [IC50 = 28.47 ppm].
