Abstract

Konsep pertanian berkelanjutan adalah dengan memanfaatkan bahan-bahan alami atau organik dan mikroorgansime sebagai dekomposer dan penyedia unsur hara bagi tanaman. Limbah-limbah seperti limbah udang dan kelapa merupakan bahan alami yang bisa menjadi aktivator alami pengurai bahan organik atau sebagai bahan pengomposan. Limbah tersebut berpeluang untuk menghasilkan bakteri positif untuk pengurai bahan organik. Tujuan penelitian ini adalah mengisolasi dan mengidentifikasi karakteristik morfologi bakteri pada limbah kulit udang dan limbah kelapa. Penelitian ini dilakukan di Laboratorium Agronomi Jurusan Perkebunan Politeknik Pertanian Negeri Samarinda dari bulan Juli sampai dengan September 2022. Isolasi bakteri dilakukan dengan metode serial dilution kemudian ditumbuhkan di media NA (Nutrient Agar) menggunakan metode spread plate. Identifikasi bakteri dilakukan dengan mengamati morfologi koloni. Isolat yang berhasil diperoleh sebanyak 44 isolat bakteri dengan isolat bakteri terbanyak berada pada perlakuan A2L2 sebanyak 9 isolat bakteri. Berdasarkan karakteristik morfologi bakteri isolat bakteri yang diperoleh termasuk ke dalam kelompok genus Bacillus dan Pseudomonas.

Abstract

Nutgrass is a common weed often found in agricultural fields. Its high population in agricultural land can have negative implications for farmers as it may prevent farmed crops from growing and producing as well. However, nutgrass has the potential to be developed into a biopesticide due to its phytochemical compounds. The purpose of this study is to identify secondary metabolite compounds present in nutgrass extract. On nutgrass extracts, the study used phytochemical screening techniques with ethanol (polar) and n-hexane (non-polar) solvents. According to the findings, ethanol and n-hexane solvents produced nutgrass extract yields of 10.81% and 0.65%, respectively. Alkaloids, flavonoids, saponins, tannins, and steroids were all present in nutgrass extracts made with ethanol, whereas only steroid components were present in extracts made with n-hexane. Saponins, tannins, alkaloids, flavonoids, and steroids are only a few of the secondary metabolite substances found in nutgrass extracts.
