Commercial Potentials and Agronomic Status of Etlingera elatior, a Promising Horticulture Plant from Zingiberaceae Family

Wualae (Etlingera elatior (Jack) R.M Smith) is one of the plants in the Zingiberaceae family, widely used in medicine ranging from rhizomes, fruits, and flowers. Empirically Wualae are usually used by people for treating skin diseases, flavoring food, a natural soap, and in Southeast Sulawesi, it is used to treat typhoid fever. This study aims to examine the antioxidant activity of Wualae (Etlingera elatior) plant. The plant extracts were extracted by maceration method, antioxidant activity test was performed by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) method. The results showed that ethanol extracts of fruits, leaves, stems and rhizomes of Wualae (Etlingera elatior) has the potential antioxidant activity with the IC50 values of 72.518 mg/L, 99.890 mg/L, 52.345 mg/L and 58.638 mg/L, respectively. and Vitamin C has IC50 value of 3,787 mg/L.

Etlingera Elatior

Daging merupakan bahan makanan sumber protein hewani yang mudah mengalami kerusakan oleh karena aktivitas mikroorganisme perusak pangan. Bunga kecombrang (Nicolaia speciosa Horan) merupakan salah satu alternatif pengawet alami, karena kandungan komponen bioaktif yaitu alkaloid, polifenol, flavonoid dan minyak atsiri. Penelitian ini bertujuan untuk mengetahui pengaruh perendaman daging sapi dalam ekstrakbunga kecombrang (Etlingera elatior) terhadap susut masak, pH dan organoleptik. Penelitian menggunakan Rancangan Acak lengkap (RAL) terdir 5 perlakuan dengan 4 ulangan. Perlakuan yang diberikan sebagai berikut: P0 = 200g daging sapi (tanpa perlakuan), P1= 200g daging sapi + 200ml aquades + 10 ml ekstrak bunga kecombrang, P2= 200g daging sapi + 200ml aquades + 20 ml ekstrak bunga kecombrang, P3= 200g daging sapi +200ml aquades + 30 ml ekstrak bunga kecombrang, P4= 200g daging sapi + 200ml aquades + 40 ml ekstrak bunga kecombrang. Variabel pengamatan penelitian meliputi susut masak, pH dan organoleptik. Berdasarkan hasil penelitian dapat disimpulkan bahwa perendaman daging sapi dalam ekstrak bunga kecombrang (Etlingera elatior) antara 10-40 ml belum dapat digunakan untuk mempertahankan kualitas daging sapi namun cenderung meningkatkan angka kualitas daging sapi sapi pada masa simpan yang lama. Perendaman daging sapi dengan ekstrak bunga kecombrang 40 ml cenderung menghasilkan nilai susust masak, dan pH daging sapi yang lebih baik pada masa simpan yang lama (susut masak 33,70-46,54 dan pH 5,25-6,08). Pada warna dan bau perendaman daging dengan ekstrak bunga kecombrang memiliki bau, warna dan tekstur yang lebih baik pada masa simpan yang lama (bau 4,06-4,48 yakni berbau khas daging, warna 2,85-3,84 yakni warna merah gelap dan 1,88-3,55 yakni agak lembek). Daging sapi dengan perendaman ekstrak bunga kecombrang yang disimpan sampai dengan 12 jam masih layak untuk dikonsumsi.Kata Kunci : bunga Kecombrang, daging sapi, susut masak, pH, organoleptik

Etlingera Elatior

Etlingera elatior is tropical ornamental plant commonly called “torch ginger” from Zingiberaceae family. Conventional breeding of E. elatior is limited by cross incompatibility, poor fruit set and low seed production. In this study irradiation of E. elatior with Gamma ray performed to induce mutation. This study was aimed to increase morphological diversity and to obtain unique morphological characters to increase the aesthetic value of E. elatior as ornamental plants and cut flower. Two genotypes of E. elatior, red and white flowers, were tested. The LD20, LD35, and LD50 were determined following intermittent (split dose) Gamma irradiation with a two-hour gap between each gamma ray shot. Red genotype E. elatior explants were irradiated with dose of 3 + 3 Gy (LD20); 4 + 4 Gy (LD35) and 5 + 5 Gy (LD50); white genotype were irradiated with a dose of 2 + 2 Gy (LD20); 2.8 + 2.8 Gy (LD35) and 3.7 + 3.7 Gy (LD50). Non-irradiated explants were set as control. The results of this study indicated that the increase in dose of gamma ray irradiation changed shoot length and number of leaves in the red genotype per explant as compared to control. Morphological changes occurred in leaf shape at 5 + 5 Gy and 3.7 + 3.7 Gy and formation of variegated leaves at 2.8 + 2.8 Gy and 5 + 5 Gy.
