Abstrak. Fenomena Plant Awareness Disparity (PAD) menggambarkan rendahnya perhatian mahasiswa terhadap tumbuhan dibandingkan objek lain, sehingga berdampak pada menurunnya kesadaran ekologis. Penelitian ini bertujuan untuk menganalisis persepsi mahasiswa calon guru biologi terhadap pembelajaran botani serta peluang penerapan Life-Based Learning (LBL) untuk menanggulangi PAD. Penelitian menggunakan pendekatan kualitatif dengan desain eksploratif. Subjek penelitian adalah 95 mahasiswa Program Studi Pendidikan Biologi Universitas Negeri Makassar yang telah menempuh mata kuliah botani. Data diperoleh melalui kuesioner terbuka dan dianalisis menggunakan teknik analisis tematik. Hasil penelitian mengungkap enam tema utama, yaitu relevansi pembelajaran botani, pengalaman belajar nyata, manfaat LBL, harapan terhadap pembelajaran, saran perbaikan, dan tantangan PAD. Mahasiswa menilai sebagian besar materi botani cukup relevan dengan kehidupan nyata, meskipun masih terdapat pembelajaran yang cenderung abstrak. Pengalaman belajar nyata melalui observasi lingkungan dan riset sederhana memperkuat pemahaman, namun tidak merata dirasakan seluruh mahasiswa. Penerapan LBL dinilai bermanfaat dalam meningkatkan pemahaman ilmiah, keterampilan pemecahan masalah dan sikap peduli lingkungan. Harapan mahasiswa mencakup adanya kegiatan lapangan, penelitian sederhana, serta praktikum aplikatif. Saran yang diajukan menekankan perlunya strategi kontekstual, peningkatan fasilitas, dan metode kreatif. Tantangan utama yang diidentifikasi meliputi keterbatasan pengetahuan tentang tumbuhan, minat belajar yang condong ke hewan, dan kebosanan terhadap materi teoretis. Penelitian ini menyimpulkan bahwa penerapan LBL berpotensi besar menjembatani kesenjangan antara teori dan praktik serta efektif untuk mengurangi PAD. Temuan ini menjadi dasar pengembangan kurikulum botani yang lebih kontekstual, aplikatif, dan berorientasi pada pengalaman kehidupan nyata mahasiswa.Kata Kunci: Life-Based Learning, Plant Awareness Disparity, Mahasiswa Calon Guru Biologi

Diabetes mellitus is a long-lasting metabolic condition characterized by elevated levels of glucose in the blood. Rhizophora mucronata, a locally abundant mangrove species in Indonesia, has attracted attention for its potential medicinal properties. The limited effectiveness of conventional herbal preparations has prompted the development of mangrove extract nanoparticles to improve the solubility, stability, and bioavailability of active compounds. This study evaluates the phytochemical profile, physicochemical properties, and antihyperglycemic activity of R. mucronata leaf extract nanoparticles. Phytochemical screening identified secondary metabolites including alkaloids, flavonoids, triterpenoids, tannins, and saponins. SEM analysis revealed irregular, agglomerated nanoparticle morphology, and EDS confirmed that carbon and oxygen were the dominant elements. XRD analysis indicated semi-crystalline characteristics, while FTIR detected key functional groups associated with organic compounds. In vivo experiments using alloxan-induced mice showed that treatment with mangrove extract nanoparticles, especially at a 15% concentration, significantly lowered blood glucose levels compared to other treatments. These findings suggest that mangrove leaf extract nanoparticles hold strong promise as an effective and stable natural antihyperglycemic agent.

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan kesadaran serta kemandirian masyarakat dalam menerapkan Pola Hidup Bersih dan Sehat (PHBS) melalui tindakan preventif yang aplikatif. Permasalahan utama yang dihadapi oleh komunitas mitra adalah keterbatasan akses informasi komprehensif mengenai pentingnya higienitas personal serta tingginya ketergantungan terhadap produk sanitasi komersial yang relatif mahal. Metode yang digunakan meliputi dua tahapan utama, yaitu edukasi interaktif mengenai urgensi PHBS dan pelatihan transfer keterampilan praktis pembuatan hand sanitizer berbasis bahan alami sesuai standar kesehatan. Pelaksanaan program ini terbukti memberikan peningkatan signifikan pada pemahaman masyarakat terkait indikator kesehatan keluarga, serta penguasaan keterampilan teknis mandiri dalam memproduksi pembersih tangan. Keberhasilan tersebut diindikasikan oleh kemampuan seluruh peserta memproduksi hand sanitizer layak pakai, didukung hasil evaluasi kuesioner yang menunjukkan bahwa mayoritas peserta (70-100%) memberikan respon "sangat setuju" terhadap seluruh aspek program. Kegiatan ini membuktikan bahwa pendekatan edukatif yang disertai transfer teknologi tepat guna mampu menstimulasi kemandirian preventif masyarakat secara berkelanjutan dalam menjaga sanitasinya.

Heavy metal contamination, particularly mercury and its derivatives, represents a serious environmental issue with profound impacts on ecosystems and human health. Methylmercury (HgCl₂) is known to be highly toxic, persistent, and capable of bioaccumulating within the food chain. Bioremediation using indigenous bacteria offers an environmentally friendly and sustainable alternative approach. This study aimed to evaluate the diversity and adaptability of soil bacteria in response to mercury (HgCl₂) exposure at different concentrations. Soil samples were incubated with and without HgCl₂, and the number of bacterial strains as well as their growth tolerance were analyzed. The results showed that at day 0, 14 strains were identified in soil without HgCl₂ and 15 strains in soil with HgCl₂. After seven days of incubation, the number of strains slightly increased to 14 and 16 in soil without and with HgCl₂, respectively. Several new strains were detected on day 7, while some were no longer observed in either the control or treated samples. Tolerance assays revealed that certain isolates, such as K7, P1, and P10, were able to grow at mercury concentrations up to 30 ppm, whereas others could only survive at lower concentrations. These variations in growth patterns suggest different adaptive mechanisms, including the potential role of mercury reductase enzymes in detoxification. The findings highlight the ability of soil bacterial communities to survive and adapt to mercury contamination, underscoring their potential role in the bioremediation of heavy metal-polluted environments.
