Abstract

Pohon enau (Arenga pinnata), dikenal juga sebagai pohon aren, merupakan salah satu dari banyak jenis flora yang ada di Indonesia. Tanaman ini memiliki fungsi produksi yang menghasilkan berbagai komoditi yang bernilai ekonomi tinggi dan berpotensi jika diusakan dengan secara baik. Seluruh bagian tanaman dapat diolah menjadi berbagai produk pangan dan non pangan. Wilayah NTB terdapat sentra produksi gula aren dan merupakan produk unggulan nasional dengan kualitas yang baik. Salah satu tempat produksi gula aren yaitu rumah produksi bapak Saiful Bahri di Desa Sesaot Lombok Barat. Gula aren yang diproduksi menggunakan cetakan tradisional berupa batok kelapa, hasil yang didapatkan berupa bentuk setengah bola dengan berat kurang lebih 1,5 kg. Harga yang ditawarkan dengan bentuk tersebut seharga Rp 20.000. Pada kegiatan pengabdian ini akan dilakukan inovasi terhadap pengolahan air nira menjadi gula aren briket.

Abstract

The plant pathogenic bacterium Xanthomonas campestris is a Gram-negative, rod-shaped bacterium that causes damage to plant leaves. This particular disease can result in significant economic losses and a reduction in the quality of agricultural products. An alternative method of dealing with this bacteria is to utilise the rhizosphere of kale (Ipomoea carnea) as a biological control. The objective of this study was to ascertain the antibacterial potential of the rhizosphere bacteria of kale (Ipomoea carnea) against the Xanthomonas campestris bacteria and to identify isolates with enhanced antibacterial efficacy against Xanthomonas campestris using the well diffusion method. A total of 13 bacterial isolates were obtained from the rhizosphere of kale, exhibiting distinctive round colonies, flat edges, and a white or cream colouration. A total of 12 gram-negative isolates and one gram-positive isolate were identified. The highest inhibitory activity against X. campestris was demonstrated by isolates R1, R3, and R11, with an average inhibitory zone diameter of 20.01 mm, 20.79 mm, and 20.57 mm, respectively. These values fell into the very strong inhibition category.
