Abstract

The use of nuclear technology, particularly irradiation using gamma rays, offers an effective solution for increasing the shelf life of marine fish. This article discusses the physics behind the use of gamma rays from Cobalt-60 and Cesium-137 sources in food irradiation. Cobalt-60 is the most commonly used source of gamma rays because it emits high-energy radiation that effectively penetrates foodstuffs, including marine fish. The irradiation process works by damaging the DNA of microorganisms that cause spoilage and disease through ionizing radiation, thereby extending the shelf life of fish without compromising nutritional quality and taste. The use of Cesium-137, although less common, is also discussed as an alternative source of gamma rays. Irradiation with gamma rays from Cobalt-60 and Cesium-137 has been proven effective in killing pathogenic microorganisms and maintaining the freshness of marine fish for longer. Challenges in implementing this technology, such as initial costs and consumer education, need to be addressed to maximize its benefits. The future prospects for food irradiation are very promising with further research and collaboration between sectors.

Abstract

Kurikulum Merdeka merupakan inovasi penting dalam pendidikan Indonesia yang menekankan pembelajaran berpusat pada siswa, penguatan kompetensi, serta pengembangan keterampilan abad ke-21. Namun, masih banyak guru yang menghadapi kendala dalam mengintegrasikan model pembelajaran dengan asesmen yang sesuai. Kegiatan pengabdian kepada masyarakat ini dilaksanakan dalam bentuk workshop di Madrasah Madani Alauddin Makassar dengan melibatkan 25 guru dari berbagai jenjang pendidikan. Metode pelaksanaan meliputi penyampaian materi, diskusi, simulasi, serta evaluasi melalui angket (pre-test dan post-test), observasi, dan wawancara singkat. Hasil pre-test menunjukkan rendahnya pemahaman guru terkait model pembelajaran (28%) dan asesmen (25%). Setelah workshop, terjadi peningkatan signifikan dengan 82% peserta lebih percaya diri merancang pembelajaran adaptif dan 79% memahami asesmen autentik. Observasi menunjukkan keterlibatan aktif peserta dalam diskusi kelompok, simulasi, dan presentasi, sementara 85% peserta menyatakan workshop bermanfaat serta dapat langsung diadaptasi di kelas. Dengan demikian, workshop ini terbukti efektif dalam meningkatkan pemahaman, keterampilan, dan kesiapan guru dalam mengimplementasikan Kurikulum Merdeka.
