Abstract

Spirulina platensis, a blue-green algae abundant in tropical regions, is rich in minerals, vitamins, fibers, and pigments, with low nucleic acid content. It has unique chromoproteins called phycobiliproteins, notably phycocyanin, used in various applications. This study aims to optimize phycocyanin extraction using different solvents (distilled water and sodium phosphate buffer pH 6.7) and methods (freeze-thaw and sonication). Spirulina platensis biomass was extracted in both solvents, then some of them was freeze for 24 and 48 hours followed by thawing overnight. The other was sonicated for 2.5 minutes, 50 Hz then soaked for 1, 2, and 3 hours. All of the samples were centrifuged at 6000 rpm for 10 minutes and the absorbance was measured using a UV-Vis spectrophotometer at wavelengths of 280, 620, and 650 nm. with freeze-thawing for 48 hours yielded the highest phycocyanin concentration (0.55%), with a yield of 11.07 and purity of 0.21. Sonication improved phycocyanin concentration, yield, and purity significantly, yielding 1.108, 25.85, and 0.26, respectively.

Abstract

Sampai saat ini, Indonesia masih kesulitan menangani persoalan sampah. Oleh karena itu, perlu dilakukan perubahan paradigma yang memandang sampah sebagai sumber daya yang memiliki nilai ekonomis dan dapat dimanfaatkan. Kkhususnya limbah anorganik seperti kaleng dan plastik banyak dimanfaatkan untuk pembuatan kriya logam, campuran beton, bahan pembuatan MMC (Metal Matrix Composites) dan bahan dasar koagulan. Untuk mendukung warga Desa Doplang meningkatkan nilai jual komoditi bunga sedap malam, Teknologi Tepat Guna (TTG) alat destilasi/ penyulingan sederhana dari limbah anorganik dibuat. Metode yang digunakan adalah dengan pendekatan community development, empowerment dan community engagement. Setelah melakukan perijinan ke mitra, sosialisasi tentang potensi limbah anorganik dan pelatihan pembuatan alat destilasi sederhana dilakukan. Alat destilasi sederhana berhasil dibuat dengan memanfaatkan limbah organik. Dari kegiatan ini, warga Desa Doplang diharapkan mampu mengekstrak minyak atsiri bunga sedap malam menjadi produk turunannya.

Abstract

Papaya leaves (Carica papaya L.) are known to contain bioactive compounds such as flavonoids, alkaloids, tannins, and saponins, which exhibit antiseptic, anti-inflammatory, antifungal, and antibacterial properties, making them promising for topical pharmaceutical preparations. However, achieving optimal physical characteristics in cream formulations requires careful selection and proportioning of emulsifiers. This study investigates the effect of varying ratios of stearic acid and triethanolamine on the physical properties of creams containing ethanol-extracted papaya leaf extract. The extract was obtained via maceration using 96% ethanol and confirmed to contain active compounds through phytochemical screening and thin-layer chromatography. Eight formulations were developed using a Simplex Lattice Design (SLD) with stearic acid concentrations ranging from 15–17% and triethanolamine from 2–4%. Physical evaluations included tests for pH, viscosity, adhesion, and spreadability. All formulations met standard of cream quality requirements, but the optimal formula was identified at 15.20% stearic acid and 3.79% triethanolamine, offering the most desirable physical characteristics. This formulation strategy demonstrates the potential for producing effective and stable papaya leaf creams, with implications for natural-based dermatological product development.

Abstract

Patchouli leaves (Pogostemon cablin) are known to contain flavonoid compounds with potential antioxidant properties. However, comparative data on flavonoid content and antioxidant activity across different extract fractions of patchouli leaves remain limited. To address this gap, the present study was conducted to analyze the total flavonoid content and evaluate the antioxidant activity of the ethanol extract and three solvent fractions—n-hexane, ethyl acetate, and wáter using the DPPH method as an indicator of free radical scavenging activity. The extraction was carried out through maceration, followed by fractionation. The determination of flavonoid content employed a colorimetric method based on the aluminum chloride reaction, while antioxidant activity was assessed using the DPPH assay. The results revealed that the ethyl acetate fraction contained the highest flavonoid concentration (1.615 ± 0.0591%) and exhibited very strong antioxidant activity, with an IC₅₀ value of 17.3909 ± 0.1327 μg/mL. These findings suggest that the ethyl acetate fraction holds significant potential as a natural antioxidant agent, with possible applications in the pharmaceutical field or nutraceutical-based health products.

Abstract

Spirulina platensis is a blue-green microalga known for its antibacterial properties, offering potential as a natural alternative in acne treatment. Acne vulgaris, often caused by Staphylococcus epidermidis, requires effective topical solutions. Gels are favored for their non-greasy texture, ease of application, and good skin absorption. This study aimed to formulate and evaluate anti-acne gels containing 25% Spirulina extract with varying Carbopol concentrations (0.5%, 1%, 1.5%). Each formulation was assessed for physical properties, stability over 21 days, and antibacterial activity against S. epidermidis. All gel formulations met quality standards for pH, homogeneity, viscosity, spreadability, and adhesiveness. The gel with 0.5% Carbopol (FI) showed the best spreadability, ideal viscosity, and good adhesiveness, along with the highest antibacterial activity, exhibiting an inhibition zone of 16.5 mm—comparable to tetracycline. In conclusion, Spirulina-based gel with 0.5% Carbopol offers an effective, stable, and natural anti-acne option. These findings highlight the potential of Spirulina as a bioactive agent in topical formulations and encourage further research for clinical applications in acne management.
