Abstract

Green synthesis of nanoparticles derived from natural compounds has emerged as a promising strategy to address increasing bacterial infections and antibiotic resistance. Unlike conventional methods that rely on toxic chemicals and high energy processes, this eco-friendly approach uses plant extracts as reducing and stabilizing agents, producing safer and more biocompatible nanoparticles. This narrative review summarizes recent findings on biosynthetic approaches, physicochemical characteristics, and antibacterial mechanisms demonstrated in experimental studies. Relevant articles published between 2015 and 2025 were retrieved from ScienceDirect, PubMed, and Google Scholar using defined eligibility criteria. The synthesis commonly produces silver, gold, or zinc oxide nanoparticles with nanoscale size (<100 nm) and high colloidal stability. These nanoparticles exhibit potent antibacterial activity through multimodal pathways, including membrane disruption, oxidative stress induction, and biofilm inhibition, including against multidrug-resistant pathogens. Overall, green-synthesized nanoparticles represent a promising and sustainable platform for antibacterial therapy; however, further standardization, toxicity evaluation, and preclinical validation are required before translation to clinical applications.

Abstract

Conventional synthesis of silver nanoparticles (AgNPs) generally uses chemical reagents that may pose environmental and health risks, such as generating toxic by-products, causing environmental pollution, and potentially affecting human health. Therefore, the development of eco-friendly synthesis methods using natural materials has become an important research focus. This study aims to synthesize AgNPs using butterfly pea flower (Clitoria ternatea) extract as a natural reducing and stabilizing agent and to evaluate their physicochemical characteristics. The synthesis was carried out through a green synthesis approach by reacting AgNO₃ solution with butterfly pea flower extract at reaction times of 0, 30, 60, 90, and 120 minutes. The formation of AgNPs was monitored using UV–Vis spectrophotometry in the wavelength range of 300–600 nm to observe the Surface Plasmon Resonance (SPR) peak. Functional groups involved in the synthesis process were analyzed using Fourier Transform Infrared (FTIR), while particle size distribution was determined using a Particle Size Analyzer (PSA). The results showed SPR peaks in the range of 380–470 nm, with maximum absorbance at 422 nm after 60 minutes, indicating the optimal synthesis condition. FTIR analysis identified –OH, C–H, C=C, and C–O functional groups derived from secondary metabolites that act as reducing and stabilizing agents. PSA results showed a dominant particle size of approximately 193 nm within the nanometer scale. These findings indicate that butterfly pea flower extract has strong potential as a sustainable and environmentally friendly biomaterial for AgNP synthesis with potential applications in health, environmental, and functional material fields.

Abstract

Olive oil (Olea europaea L.) is a high-value vegetable oil rich in unsaturated fatty acids and bioactive compounds beneficial to health. However, variability in quality and the risk of adulteration require accurate chemical characterization. This study aims to analyze the fatty acid profile and chemical characteristics of olive oil using a combination of Gas Chromatography–Mass Spectrometry (GC–MS) and Fourier Transform Infrared Spectroscopy (FT–IR). Olive oil samples were analyzed before and after 12 hours of ultrasonic treatment, preceded by a methylation process to form fatty acid methyl esters. GC–MS was used to identify fatty acid components based on retention time and mass spectra, while FT–IR was employed to observe the main functional groups of triglycerides. The GC–MS results showed oleic acid as the dominant component, increasing from 58.36% before to 68.59% after ultrasonic treatment, followed by palmitic and linoleic acids. FT–IR spectra exhibited characteristic peaks at ~2924 cm⁻¹, 1745 cm⁻¹, and 1163 cm⁻¹, confirming the triglyceride structure. The combination of GC–MS and FT–IR proved effective for evaluating the quality and authenticity of olive oil.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kemampuan pemecahan masalah matematika siswa melalui pendampingan edukatif dalam kegiatan Pelatihan dan Lomba Matematika (PLM) yang diselenggarakan oleh MEC RAKUS Makassar di Kabupaten Takalar. Latar belakang kegiatan ini didasarkan pada rendahnya minat dan kemampuan siswa dalam menyelesaikan soal matematika non-rutin, khususnya yang berbasis kompetisi dan menuntut kemampuan berpikir tingkat tinggi. Pendampingan edukatif dirancang sebagai solusi untuk menjembatani kesenjangan antara kebutuhan kompetensi siswa dan praktik pembelajaran yang masih berorientasi pada soal rutin. Metode pelaksanaan menggunakan pendekatan deskriptif kuantitatif dengan tiga tahapan utama, yaitu persiapan, pelaksanaan, dan evaluasi. Kegiatan meliputi penguatan konsep matematika, latihan soal berbasis olimpiade, serta simulasi kompetisi yang dilaksanakan secara intensif. Subjek kegiatan adalah 30 siswa tingkat SMP yang mengikuti program PLM. Instrumen yang digunakan berupa pre-test dan post-test untuk mengukur peningkatan kemampuan siswa. Hasil analisis menunjukkan adanya peningkatan nilai rata-rata dari 66,87 pada pre-test menjadi 77,30 pada post-test. Selain itu, terjadi penurunan standar deviasi dari 13,032 menjadi 9,513 yang menunjukkan peningkatan pemerataan kemampuan siswa. Hasil ini mengindikasikan bahwa pendampingan edukatif yang terintegrasi dengan pengalaman kompetisi efektif dalam meningkatkan kemampuan kognitif sekaligus kesiapan mental siswa. Kegiatan ini juga memberikan pengalaman belajar yang lebih bermakna melalui keterlibatan aktif siswa dalam proses pembelajaran. Dengan demikian, program PLM dapat menjadi model pembinaan matematika nonformal yang efektif dalam mengembangkan kemampuan berpikir kritis, strategi pemecahan masalah, serta kepercayaan diri siswa dalam menghadapi kompetisi matematika secara berkelanjutan dan adaptif.

Abstract

Pembelajaran sains abad ke-21 menuntut keterampilan proses ilmiah melalui kegiatan praktikum laboratorium. Namun, pemahaman siswa sekolah menengah mengenai penggunaan alat laboratorium dan penerapan keselamatan serta kesehatan kerja (K3) masih belum optimal. Kondisi ini juga ditemukan pada siswa SMA IT Al Qalam Gowa yang telah melaksanakan praktikum tetapi belum didukung program pengenalan laboratorium yang sistematis. Program pengabdian ini bertujuan meningkatkan literasi laboratorium siswa melalui pemahaman fungsi alat, prosedur praktikum dasar, dan standar keselamatan kerja. Metode pelaksanaan meliputi tiga tahap utama, yaitu persiapan melalui koordinasi dan penyusunan materi, pelaksanaan berupa penyuluhan, demonstrasi, dan praktik sederhana, serta evaluasi melalui diskusi interaktif dan observasi partisipasi siswa. Hasil kegiatan menunjukkan peningkatan pemahaman siswa terhadap penggunaan alat laboratorium, kepatuhan terhadap prosedur praktikum, serta kesadaran penerapan K3. Pendekatan berbasis praktik langsung juga meningkatkan kepercayaan diri dan minat siswa terhadap pembelajaran sains berbasis eksperimen. Program pengenalan laboratorium ini efektif dalam menjembatani kesenjangan antara ketersediaan fasilitas dan kesiapan siswa, serta berpotensi memperkuat budaya keselamatan laboratorium dan kualitas pembelajaran sains di sekolah menengah.
