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

Education based on environmental awareness plays an essential role in shaping a generation that cares about the environment and sustainability. One effective approach to raising this awareness is by integrating simple science that focuses on the use of natural materials in everyday life. Lemongrass (Cymbopogon citratus), which is rich in bioactive compounds like citronella and geraniol, offers various benefits, including antibacterial and anti-inflammatory properties. This program aims to educate students, teachers, and parents on how to process lemongrass into eco-friendly liquid soap, as well as teach practical skills that can be applied in daily life. Through this training, students will not only understand the benefits of natural materials but also acquire skills that can be used to create economic opportunities based on environmentally friendly products. This program also encourages a healthy and sustainable lifestyle by reducing dependence on harmful chemical-based commercial cleaning products. Furthermore, the program aims to introduce the concept of entrepreneurship based on natural products, which can create new economic opportunities at the local level. The implementation of this community service program will involve students, teachers, and parents at SD Negeri 2 Pampangan, Sekincau District, West Lampung. Through hands-on training, it is expected to have a significant positive impact on improving the competence of students, teachers, and parents in effectively utilizing natural resources. Additionally, this program has the potential to serve as a model that can be implemented in other schools across Indonesia, expanding its positive impact and raising environmental awareness among the younger generation.
