Abstract

Food preservation is a crucial aspect in maintaining the quality, safety, and nutritional value of products, particularly in Indonesia with its rich diversity of food resources. Conventional methods such as drying, salting, and freezing are still dominant but have limitations in preventing food spoilage caused by microbiological and environmental factors. One emerging innovation in modern preservation technology is the use of gamma irradiation. This technology effectively eliminates pathogenic microorganisms without damaging the physical and chemical quality of food products. This literature study aims to understand the working mechanism of gamma irradiation, its impact on food, and its role in enhancing food production in Indonesia. Gamma irradiation uses radiation from radioactive isotopes such as Cobalt-60 to damage microbial DNA, thereby extending product shelf life. The technology is considered safe, leaves no residues, is energy-efficient, and environmentally friendly. However, its application in Indonesia remains limited due to a lack of public awareness and persistent negative stigma surrounding nuclear technology. Public education is key to increasing societal acceptance of food irradiation. With proper implementation, gamma irradiation technology holds significant potential in reducing food waste, enhancing food safety, and supporting national food security.

Abstract

Nuclear energy has become a promising alternative in overcoming dependence on fossil fuels and improving energy efficiency. In this article, the author discusses the process of generating safe and environmentally friendly nuclear energy. Nuclear energy is produced through atomic nucleus reactions, such as nuclear fission, which create large amounts of energy. Nuclear reactors, such as nuclear power plants, utilize air as both a coolant and a moderator, generating electrical energy through a heat conversion process. The advantages of nuclear energy include its high energy density, better energy efficiency, and minimal greenhouse gas emissions. However, nuclear power plants also have disadvantages such as the risk of nuclear accidents and the high-level nuclear waste they produce. In summary, nuclear energy offers an effective solution for improving energy efficiency and reducing dependence on fossil fuels, but it must be balanced against its associated drawbacks and risks.

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.

Abstract

The high cellulose content and abundance of oil palm fiber make it an exceptionally promising sustainable source for nanocellulose production in advanced material science. This study executes a thorough comparative analysis of different isolation strategies covering chemical, mechanical, and enzymatic approaches to derive nanocellulose specifically for functional material development. We aim to clarify how each distinct isolation path dictates the final structural integrity, morphology, and thermal stability of the extracted nanocellulose. By synthesizing data through a systematic literature review, this research evaluates critical metrics such as the crystallinity index and fiber diameter, which directly influence the performance of functional composites. Our analysis reveals that while chemical techniques like acid hydrolysis are superior for achieving high crystallinity, mechanical processes like high-pressure homogenization provide enhanced aspect ratios despite their heavy energy demands. Additionally, enzymatic methods offer a greener pathway, though they often trade speed for environmental benefits. Ultimately, this comparative review serves as a strategic roadmap for researchers to select the most appropriate isolation method based on intended applications, ranging from high-strength bio-composites to flexible electronic components.
