Abstract
INDONESIA:
Pegagan (C. asiatica), termasuk famili Apiaceae (Umbelliferae) dan mengandung asiatikosida, asam asiatikat, madekasoida dan lain-lain. Kandungan metabolit sekunder pegagan berkhasiat untuk daya ingat, luka bakar, hipertensi, penyakit syaraf, asma, bronkitis, dan uretritis. Kebutuhan metabolit sekunder yang tinggi bisa didapatkan melalui kultur kalus. Penelitian ini bertujuan untuk mengetahui konsentrasi kombinasi Zat Pengatur Tumbuh 2,4-Dichlorophenoxyacetic Acid (2,4-D) dengan air kelapa pada media MS yang paling efektif untuk menginduksi kalus dari eksplan daun pegagan (C. asiatica).
Penelitian ini menggunakan RAL dengan dua faktor. Pertama adalah konsentrasi 2,4-D (0,1, 2 dan 3 mg/L) dan kedua adalah konsentrasi air kelapa (10, 15 dan 20%). Parameter yang diamati yaitu munculnya eksplan berkalus (hari), persentase kalus (%), berat basah kalus (gr) dan morfologi kalus (warna dan tekstur kalus). Data kuantitatif diuji dengan ANAVA Two-Way. Sedangkan data kualitatif ianalisis secara deskriptif. Pengamatan dilakukan secara harian, dua minggu dan tempat minggu setelah tanam (HST).
Hasil uji ANAVA menunjukkan perlakuan 2,4-D berpengaruh terhadap hari munculnya eksplan berkalus, persentase dan berat basah kalus. Perlakuan air kelapa berpengaruh terhadap berat basah kalus. Interaksi 2,4-D dengan air kelapa berpengaruh terhadap persentase dan berat basah kalus. Perlakuan kombinasi 1 g/L 2,4-D + 10% air kelapa merupakan kombinasi yang paling efisien untuk mendapatkan kalus terbaik dengan berat basah kalus 0,81 gr dengan persentase kalus 78,25%. Pengamatan morfologi (warna dan tesktur kalus) menunjukkan kalus berwarna kekuningan dan bertekstur kompak. Morfologi kalus seperti inilah yang dapat digunakan dalam produksi metabolit sekunder.
ENGLISH:
Pennywort (C. asiatica), included to the family Apiaceae (Umbelliferae) and contains asiaticosides, asiatic acid, madecassoside, madecassic acid and others. The secondary metabolites of Pennywort efficacious for memory, burns wound, hypertension, neurological diseases, asthma, bronchitis and urethritis. High needs of Pennywort secondary metabolites can be obtained through callus culture.
This study aims to determine the concentration of a combination of 2,4-D PGRs with coconut water on the most effective MS medium to induce callus from leaf explants of Pennywort (C. asiatica). This study was designed using a Completely Randomized Design with two factors. The first is the concentration of 2,4-D (0,1, 2 and 3 mg/L), the second is the concentration of coconut water (10, 15 and 20 %). Parameters observed: emergence of callus explants (day), the percentage of callus (%), callus fresh weight (gr) and callus morphology (color and texture of the callus). Quantitative data were tested by ANOVA Two-Way, while the qualitative data were presented descriptively. Observations are made daily, two weeks and four weeks after planting (DAP ).
ANOVA test results showed treatment of 2,4-D effect on the appearance of callus explants, callus percentage and fresh weight. Coconut water tratment effect on callus fresh weight. Interaction between 2,4-D and coconut water affect the callus percentage and fresh weight. The treatment combination of 1 mg/L 2,4-D + 10% coconut water is the most efficient combination to obtain the best callus fresh weight (0,81 gr) and percentage 78,25%. Morphology (color and texture callus) in this medium showed callus yellowish and compact texture. Callus morphology such as these can be used in the production of secondary metabolites.
