Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) yang dilaksanakan oleh Program Studi Teknik Biomedis ITERA di Kuttab Anas bin Malik bertujuan untuk meningkatkan kesadaran dan pengetahuan siswa mengenai pentingnya kesehatan mental sebagai faktor yang memengaruhi cara berpikir, berperilaku, dan berinteraksi sosial. Latar belakang kegiatan ini didasarkan pada meningkatnya permasalahan kesehatan mental pada anak dan remaja serta adanya perilaku bullying di lingkungan pendidikan yang berdampak negatif terhadap kondisi emosional, kepercayaan diri, dan perkembangan sosial akademik siswa. Selain itu, keterbatasan pemahaman siswa terkait pengelolaan emosi dan interaksi sosial positif, serta belum adanya program edukasi kesehatan mental yang terstruktur, menjadi dasar pelaksanaan kegiatan ini. Metode yang digunakan berupa pendekatan edukatif dan interaktif melalui penyampaian materi mengenai empati, bullying dan dampaknya, serta pembiasaan perilaku sosial positif dengan teknik role play, drama, presentasi interaktif, dan lagu edukatif yang dilaksanakan dalam tiga tahap, yaitu pra-sosialisasi, sosialisasi, dan pasca-sosialisasi. Hasil kegiatan menunjukkan adanya peningkatan pemahaman siswa terhadap kesehatan mental serta terbentuknya perilaku sosial yang lebih positif. Kegiatan ini juga berkontribusi dalam menciptakan lingkungan sekolah yang lebih aman, nyaman, dan kondusif serta mendukung upaya pencegahan bullying secara efektif.

Abstract

Background: The increasing spread of Aedes aegypti as a vector of dengue disease has encouraged the exploration of safer, plant-based larvicidal materials. This study aimed to identify the phytochemical constituents of green betel leaf (Piper betle L.) extract and to develop a bio-larvicidal granule formulation as a modified dosage form. Phytochemical screening was conducted to identify bioactive compounds potentially associated with larvicidal activity. Methodology: Granules were prepared using the wet granulation method, employing polyvinylpyrrolidone (PVP) as a binder and lactose as a filler. The formulated granules were further evaluated through physical characterization tests, including flow rate, angle of repose, and dispersion time, to assess their suitability as a granular dosage form. Findings: The results demonstrated that all formulations exhibited acceptable flow properties, appropriate angles of repose, and rapid dispersion in water, indicating favorable handling and application characteristics. The flow rate test results showed that granules with concentration variations of 25%, 50%, 75%, and 100% exhibited flow rates of 71.4 g/s, 62.5 g/s, 50 g/s, and 45.5 g/s, respectively. Physical evaluation demonstrated that the granules had acceptable angles of repose (31°–36°) and dispersion time (20–25 seconds). Contribution: This study was conducted as a step toward developing an environmentally safe, natural-material-based biolarvicide
