Abstract

Resin jernang (dragon blood) merupakan getah termahal di dunia. Resin tersebut diperoleh dari  buah jernang yang tumbuh hanya di pulau Sumatra dan kalimatan. Resin jernang sangat diminati oleh Negara Cina, Hongkong, dan Singapura, karena mengandung senyawa dracohordin yang berpotensi sebagai bahan obat secara biologis dan aktivitas farmakologis seperti antimikroba, antivirus, antitumor, dan aktivitas sitotoksik. Proses ekstraksi resin jernang dari buah jernang secara konvensional secara basah dengan metode maserasi merupakan salah satu cara pengolahan buah jernang yang dilakukan oleh masyarakat pengolah jernang di Kabupaten Bireuen Provinsi Nangroe Aceh Darussalam, Namun masih ada kendala yang cukup signifikan yaitu.mutu rendemen yang diperoleh lebih rendah dibandingkan dengan rendemen resin jernang .dari.teknologi Inovasi yang dilakukan oleh Bambang, dengan proses ekstraksi maserasi menggunakan pelarut metanol menghasilkan rendemen yang lebih tinggi dari pada proses ekstraksi metode maserasi yang dilakukan oleh kelompok pengolah jernang di Kabupaten Bireuen, akan tetapi penggunaan metanol sebagai pelarut akan menaikkan biaya produksi karena harganya relatif lebih mahal dan tidak ramah lingkungan. Penelitian ini melakukan proses ekstraksi dua tahap yaitu metode  maserasi .dan metode under kritis pelarut dengan  menggunakan pelarut air, karena harganya murah, jumlah melimpah dan ramah lingkungan. Hasil  penelitian diperoleh mutu resin jernang yang lebih baik dari resin jernang yang diperoleh kelompok pengolah jernang di kabupaten Bireuen. Dengan metode  maserasi didapatkan kelas mutu resin jernang kelas A berdasarkan  spesifikasi persyaratan mutu jernang (SNI 1671:2010)  dengan kadar.resin(b/b) 73%,  Kadar air(b/b) 6,8%,  Kadar abu(b/b) 7%,   kadar pengotor(b/b) 32%, titik leleh 88oC dan bewarna merah. Sedangkan  perlakuan dua tahap diperoleh kelas mutu antara kelas A dan Mutu super dengan.kadar.resin(b/b).86%, Kadar air(b/b) 6,5%, Kadar abu(b/b) 2,8%, kadar pengotor(b/b) 9%, titik leleh 88oC dan bewarna merah tua.

Abstract

The application of magnetite (Fe3O4) nanoparticle adsorbent for the removal of methylene blue from ferric nitrate nonahydrate by sol-gel method. This study was conducted to determine the effect of variations in calcination temperature and stirring time on density, and adsorption power of magnetite (Fe3O4) nanoparticles on methylene blue with variations in stirring time of 2 hours; 3 hours; 4 hours; 5 hours, and 6 hours, as well as variations in calcination temperature of 200°C; 250°C; 300°C; 350°C and 400°C. Characterization of magnetite (Fe3O4) nanoparticles was carried out using XRD, and SEM instruments. Methylene blue concentration after adsorption was measured using Uv-Vis Spectrophotometer. Determination of adsorbent surface area was done by iodine absorption test. The results showed a decrease in density along with the increase in calcination temperature and the longer the stirring, the density value will increase. Magnetite (Fe3O4) nanoparticles effectively increase the adsorption capacity of methylene blue, with the best results at a stirring time of 6 hours and a calcination temperature of 400°C the concentration after adsorption drops to 1.7316 ppm. The best iodine adsorption capacity is found in the sample of 6 hours stirring time and 200°C calcination temperature, which is 1027.89 mg/gr. The crystal size obtained based on calculations from the Scherrer equation at a variation of 3 hours stirring time and 200°C calcination temperature is 0.2 nm and the surface morphological structure of magnetite (Fe3O4) nanoparticles at the same stirring time and calcination temperature looks clustered with sizes ranging from 0.4 nm to 0.9 nm.

Abstract

This study aims to evaluate the effect of maceration time and composition ratio of betel leaf (Piper betle L.) and lemongrass (Cymbopogon nardus) extracts on the characteristics and antibacterial activity of natural floor cleaners. The extraction method used was maceration with soaking time variations of 2–6 days and extract composition ratios of 1:0, 0:1, 1:1, 1:2, and 2:1. The parameters analyzed included pH, density, organoleptic properties, and antibacterial activity using the colony counter method. The results showed that the pH increased from 5.2 to 7.2 with longer maceration time, while the density remained relatively stable in the range of 0.90–0.93 g/mL. Antibacterial activity also increased with extraction time, with the highest effectiveness observed at 6 days of maceration, achieving a bacterial reduction of 66.41%. Organoleptic evaluation indicated that the product was generally acceptable to panelists, with neutral to favorable responses. The optimal formulation was obtained at 6 days of maceration with a 1:2 ratio of betel leaf to lemongrass extract, producing favorable physicochemical properties and the highest antibacterial activity. This study demonstrates the potential of natural ingredients as eco-friendly and safe alternatives for floor cleaning products.

Abstract

Body scrub is a skincare product designed to exfoliate dead skin cells. Bidara leaf extract (Ziziphus mauritiana Lamk) was selected for its flavonoid, saponin, and tannin content, which contribute to antibacterial and antioxidant properties, while Epsom salt functions as an exfoliating agent that aids in dead skin removal and enhance skin regeneration. This study involved variations in bidara leaf extract concentration (0–5%) and Epsom salt concentration (10–50%). The formulations were evaluated through physical quality tests, including pH, homogeneity, adhesion, spreadability, organoleptic properties, antibacterial activity, and antioxidant activity. Results indicated that the formulation with 1% bidara leaf extract and 20% Epsom salt yielded the best outcomes, with a pH of 5.2 (compliant with SNI standards for topical preparations), good homogeneity, soft texture, and high panelist acceptance, particularly for sensitive skin. Antibacterial testing revealed the highest activity at 1% extract concentration, with an inhibition zone of 23 mm against Staphylococcus aureus. Antioxidant activity demonstrated free radical inhibition with an IC50 value of 18.94 µg/mL. These findings suggest that body scrub formulations incorporating bidara leaf extract and Epsom salt hold potential as natural, effective, and environmentally friendly skincare products.
