Abstract

Penelitian ini merupakan tinjauan sistematis terhadap pengembangan serat nanofiber berbasis Poly(vinyl) alcohol (PVA) yang dimodifikasi dengan ekstrak daun pepaya (Carica papaya L.) dan daun sirsak (Annona muricata L.) sebagai inovasi bahan aktif untuk perawatan jerawat (acne treatment). Dengan menggunakan metode Systematic Literature Review (SLR), studi ini mengidentifikasi artikel-artikel ilmiah dari berbagai basis data (Google Scholar, PubMed, ScienceDirect, dan lainnya) dalam rentang 10 tahun terakhir yang membahas sintesis nanofiber, teknologi elektrospinning, dan aplikasi bahan alam sebagai antibakteri. Hasil kajian menunjukkan bahwa daun pepaya dan daun sirsak mengandung senyawa aktif seperti flavonoid, saponin, dan acetogenin yang bersifat anti-inflamasi, antioksidan, serta antibakteri. Kombinasi kedua ekstrak tersebut dalam matriks PVA melalui teknik elektrospinning berpotensi menghasilkan serat nanofiber dengan karakteristik fisikokimia yang mendukung efektivitas terapi topikal jerawat. Studi ini merekomendasikan kelanjutan pengembangan formulasi dan pengujian in vitro/in vivo guna memastikan keamanan dan efikasi nanofiber berbahan dasar alami untuk aplikasi dermatologis berkelanjutan.

Abstract

The global escalation of antimicrobial resistance (AMR) necessitates the exploration of natural sources of antibacterial agents. This study examined the ethanolic leaf extract of Melaleuca leucadendra's phytochemical composition, chemical profile, and antibacterial activity. Alkaloids, flavonoids, saponins, tannins, phenolics, terpenoids, and steroids were all detected by phytochemical screening. The quantitative total flavonoid content (TFC) of the extract was 17.78 mg QE/g, while the total phenolic content (TPC) was 292.43 mg GAE/g extract. Gas Chromatography–Mass Spectrometry (GC–MS) analysis identified oxygenated esters (18.86%), oxygenated aromatics (15.22%), phenolic derivatives (13.44%), and flavonoids (12.86%), methoxylated aromatics and terpenoids (5.34%), phytol, and fatty acid derivatives. These metabolite classes are widely reported to exert antibacterial effects through multiple mechanisms such as membrane disruption, enzyme inactivation, and inhibition of nucleic acid synthesis. Antibacterial testing against Staphylococcus aureus and Escherichia coli using the agar diffusion method showed a concentration-dependent response, with the highest activity at 80% extract (15.67 ± 0.58 mm and 15.33 ± 0.58 mm inhibition zones, respectively). Raman spectroscopy confirmed the interaction between polymer molecules and secondary metabolite compounds in the extract, thereby potentially enhancing antibacterial properties. These findings highlight that the antibacterial activity of M. leucadendra is mediated by the synergistic interplay of phenolics, flavonoids, methoxylated aromatics, terpenoids, and fatty acids. The findings offer compelling proof that M. leucadendra is a viable natural source for the creation of antibacterial compounds that will lessen antibiotic resistance.

Abstract

Telah diimplementasikan modem detektor gempa di kota Krui, Kabupaten Pesisir Barat, Provinsi Lampung pada Bulan Agustus 2025. Wilayah yang berada di area ring of fire ini memerlukan banyak sensor untuk mendeteksi gempa agar mitigasi bencana dapat dilaksanakan dengan baik. Oleh karena itu, riset yang dilaksanakan oleh Jurusan Fisika dengan output berupa modem detektor gempa berbasis sensor getaran dipasang di dua lokasi berbeda di Krui. Penentuan lokasi tersebut ditetapkan oleh tim bekerja sama dengan Badan Penanggulangan Bencana Daerah (BPBD) Krui setelah melakukan serangkaian survey di beberapa tempat. Setelah lokasi pemasangan diputuskan, BPBD mengerahkan komunitas nelayan di sekitar Pantai Walur dan warga di Kampung Sunda untuk membantu tim dalam proses instalasi modem dan sel surya yang menjadi sumber tenaga listrik mandiri bagi detektor. Data yang diukur oleh sensor pada modem dapat dipantau melalui website yang telah dibangun oleh tim riset Jurusan Fisika, FMIPA, Universitas Sriwijaya.

Abstract

Socialization activities have been carried out regarding the application of iron sand nanomagnetic fertilizer (Fe3O4) on corn plants to the villagers of Pulau Semambu Ogan Ilir, South Sumatra. This community service activity is part of the integration of the research results that have been carried out. From the results of the study, it was found that at the same growing age, corn added with nano-magnetic iron sand, both simaxx + nanomagnetic iron sand and silica + nanomagnetic iron sand, had a faster growth of about 100 cm compared to corn that was only given simaxx fertilizer. which is about 45-50 cm. Research results and observational data were then collected and analyzed to evaluate the effectiveness of using Fe3O4 nanomagnetic fertilizer on corn plants. Apart from being disseminated to corn farmers, research results are also used as teaching material to be conveyed to students in material physics courses. Integrating research results with community service activities and material physics lectures has increased the practical use of research results and provided wider benefits for society and students.
