Abstract: | Kemangi merupakan tumbuhan yang memiliki potensi sebagai tumbuhan obat. Salah satu bagian tumbuhan daun kemangi yang dijadikan obat alternatif adalah daun. Daun kemangi mengandung senyawa aktif antara lain yaitu flavonoid, saponin, tanin, dan minyak atsiri. Tujuan penelitian ini adalah untuk mengetahui kemampuan daun kemangi sebagai pengawet alami pada ikan kembung. Penelitian dilaksanakan secara in vitro, dengan melakukan observasi terhadap karakteristik fisik, kimia, dan mikrobiologis ikan kembung yang diberi perlakuan perendaman ekstrak daun kemangi 4 dan 8 jam. Variasi konsentrasi daun kemangi yang digunakan adalah 0, 25, 50, 75, dan 100%. Hasil penelitian menunjukkan bahwa, kualitas fisik sampel penyimpanan 4 jam, terlihat baik dan layak konsumsi pada semua perlakuan. Penyimpanan sampel selama 8 jam menunjukkan penurunan kualitas fisik ikan, terlihat dari warna, mata, insang, lendir, aroma dan tekstur. Kualitas mikrobiologis ikan dianalisis dengan metode angka lempeng total. Jumlah total bakteri bakteri semakin kecil seiiring dengan peningkatan konsentrasi ekstrak daun kemangi. Basil is a plant that has potential as a medicinal plant. One part of the basil plant which is used as an alternativ medicine is the leaves. Basil leaves contain active compounds, including flavonoids, saponins, tanins, and essensial oils. The purpose of this study was to determine the ability of basil leaves as a natural preservative in mackerel. The research was cariied out in vitro, by observing the physical, chemical, and microbiological characteristicts of mackerel which were treated with 4 and 8 hours of soaking basil leaf extract. Variations in the concentration of basil leaves used were 0, 25, 50, 75 and 100%. The result showed that the physical quality of the 4 hour strorage samples looked good and fit for consumption in all treatments. From eye color, gills, mucus, scent, and texture. The microbioloical quality of fish was analyzed by the total plate number method. The total number of bacteria decreased as the concentration of basil leaf extract increased. |
