Abstract

This study aimed to isolate and characterize endophytic bacteria from black turmeric rhizomes (Curcuma aeruginosa Roxb) and test their potential as antibacterial agents against Streptococcus pneumoniae. This experimental research began with the isolation of endophytic bacteria from surface-sterilized black turmeric rhizomes. The obtained pure isolates were characterized macroscopically (colony shape, margin, elevation, pigment) and microscopically (cell shape, Gram staining). The growth curve of potential isolates was determined, and antibacterial activity was tested using the disc diffusion method against S. pneumoniae, with ciprofloxacin as a positive control. Six endophytic bacterial isolates (PS1, PS2, PS3, PS4, PS5, PS6) were successfully isolated, showing variations in colony morphology, and all were classified as Gram-negative bacilli. All isolates exhibited strong antibacterial activity against Streptococus pneumoniae, with inhibition zone diameters ranging from 15.3 mm to 20.6 mm. Black turmeric rhizomes (Curcuma aeruginosa Roxb) harbor diverse endophytic bacteria with significant potential as antibacterial agents against the pneumonia pathogen, Streptococcus pneumoniae.

Abstract

Paprika mengandung jumlah vitamin C yang signifikan, paprika dikenal karena khasiatnya yang sangat bermanfaat bagi kesehatan, termasuk kemampuannya untuk menangkal radikal bebas dan bertindak sebagai antioksidan bagi tubuh. Studi ini menggunakan pelarut etanol dan metanol untuk mengukur kandungan vitamin C pada  paprika oranye dan kuning. Penelitian ini dilakukan di Laboratorium Kimia Universitas Trunojoyo Madura pada Januari 2025. Menggunakan etanol dan metanol sebagai pelarut, prosedur maserasi digunakan untuk mengekstrak paprika. Panjang gelombang maksimum juga ditentukan. Pemeriksaan sampel ini menunjukkan ymax sebesar 373,5 nm. Persamaan y = 0,0006 x + 0,019 menunjukkan linearitas. Analisis kuantitatif dilakukan pada rentang panjang gelombang 250–400 nm menggunakan spektrofotometri UV-Vis. Pelarut etanol menghasilkan 340 mg/100 g vitamin C pada paprika kuning, sedangkan pelarut metanol menghasilkan 562,5 mg/100 g. Pelarut etanol menghasilkan 215 mg/100 g vitamin C dari paprika oranye, sedangkan pelarut metanol menghasilkan 562,5 mg/100 g. Hasil uji desain blok kelompok acak lengkap dengan y = 0,05 menunjukkan perbedaan yang signifikan dalam jumlah vitamin C yang terdapat pada setiap sampel.

Abstract

Niacinamide is the amide form of vitamin B3. Other forms of vitamin B3 include niacin (nicotinic acid). Polyvinylpyrrolidone (PVP) is a biodegradable and air-soluble polymer derived from the monomer N-vinylpyrrolidone. Gels are water-rich preparations and have better potential as topical drug delivery preparations compared to ointments because they are non-sticky, require low energy during formulation, are stable, and have aesthetic value. The purpose of this study was to evaluate the physical qualities of PVP-based niacinamide gel preparations based on physical quality parameters, including organoleptic test, ligninogenicity test, pH test, viscosity test, adhesiveness test, and spreading power test. The method used in this study was an experimental method carried out to determine the physical qualities of a good gel. The results of the study showed that the PVP-based niacinamide gel preparation produced had a thick gel texture, transparent color, odorless, homogeneous, an average pH value of 16.6, an average viscosity value of 2673.6 - 2179.6, an average spreadability value of 6.2 - 6.3, and an average adhesiveness value of 4.67 - 4.46. Based on these results, the PVP-based niacinamide gel preparation had physical quality that met the requirements according to good criteria.
