Abstract

This study demonstrates the performance of platinum nanoparticles (Pt NPs) as contrast agents for computed tomography (CT). Synthesized through pulsed laser ablation, Pt NPs were stabilized in carboxymethyl cellulose (CMC). In CT imaging evaluations, the CMC-stabilized Pt NPs generated significantly higher Hounsfield Unit (HU) values and contrast-to-noise ratio (CNR) than both their DIW-based counterparts and a conventional iodine-based agent. Remarkably, this enhanced contrast was achieved at substantially lower ppm concentrations, highlighting the potential of CMC-stabilized Pt NPs to offer a more efficient and powerful alternative to current clinical standards.

Abstract

Pengelolaan limbah ternak sapi yang belum optimal masih menjadi masalah lingkungan dan kesehatan kerja di masyarakat pedesaan. Kegiatan pengabdian kepada masyarakat ini bertujuan mengurangi risiko pencemaran dan bahaya kerja melalui pemberdayaan peternak berbasis Keselamatan dan Kesehatan Kerja (K3) dalam perencanaan dan pembangunan biodigester skala komunitas. Kegiatan dilaksanakan di Kelompok Bina Lestari Desa Tangkisan, Kabupaten Purworejo, dengan sasaran kelompok peternak dan masyarakat sekitar. Metode yang digunakan meliputi pendekatan partisipatif melalui survei lapangan, sosialisasi, penyusunan Job Safety Analysis (JSA), pendampingan teknis pembangunan biodigester, serta monitoring dan evaluasi. Hasil kegiatan menunjukkan peningkatan pengetahuan dan kesadaran masyarakat terhadap potensi bahaya kerja, pentingnya penerapan K3, serta manfaat biodigester dalam pengelolaan limbah dan penyediaan energi alternatif. Selain itu, berhasil dibangun satu unit biodigester kapasitas 4 m3. Pendekatan preventif K3 terbukti efektif dalam mendukung pembangunan biodigester yang aman, berkelanjutan, dan meningkatkan kemandirian kelompok ternak Bina Lestari.
