Abstract

Eksopolisakarida (EPS) merupakan polisakarida yang disekresikan oleh mikroba keluar dinding sel, salah satunya oleh bakteri asam laktat (BAL). Kefir kolostrum merupakan minuman fermentasi yang berpotensi sebagai sumber BAL. Penelitian ini bertujuan untuk mendapatkan EPS dari BAL hasil kefir kolostrum. Untuk mencapai tujuan tersebut, isolat BAL hasil fermentasi kefir kolostrum diuji kemampuannya dalam menghasilkan EPS melalui pengamatan morfologi pada media MRSA dan karakter isolat ditentukan melalui identifikasi mikroskopik. Produksi EPS dilakukan dengan menumbuhkan kultur pada media MRSB dan dipisahkan dengan metode sentrifugasi. Analisis kandungan kadar total gula EPS diuji dengan metode fenol-sulfat. Hasil penelitian menunjukkan bahwa ada 13 isolat BAL penghasil EPS yaitu BEK 1-13 dengan 9 isolat berbentuk mucoid dan 4 isolat ropy. Produksi EPS tertinggi diperoleh dari isolat BEK 13 yaitu 4840 mg/L,  sedangkan kadar gula EPS tertinggi diperoleh dari isolat BEK 1 sebesar 579,56 mg/L.http://dx.doi.org/10.23960/aec.v5.i1.2020.p65-73

Abstract

This Microsoft Word optimization training aims to enhance the skills of teachers at Sekolah Dasar Negeri 2 Pampangan in utilizing information technology to support administrative tasks and learning. The activity was conducted offline in two main sessions: material delivery and practical simulations. The training material covered both basic and advanced features, such as mail merge, page layout, and document collaboration. A total of 30 participants attended the training and received direct guidance. Evaluation through questionnaires and observations showed that over 94% of participants understood and were able to apply the material effectively. This training proved to be effective in improving teachers' work efficiency and the quality of documents produced, as well as having a significant impact on increased productivity and professionalism in carrying out administrative tasks. Furthermore, the training strengthened teachers' digital literacy, accelerated technology adoption in learning, and supported their role as drivers of education in the digital era. However, limitations in equipment and basic computer skills remain challenges to be addressed in the future. This training provides an important contribution to strengthening teachers' digital literacy and improving the quality of education in elementary schools.
