| dc.description.abstract | Kappaphycus alvarezii merupakan komoditas rumput laut unggulan Indonesia, namun ketersediaan bibit berkualitas masih terkendala oleh penurunan mutu genetik, penyakit, dan perubahan iklim. Kultur jaringan menjadi alternatif untuk menghasilkan bibit unggul secara massal. Penelitian ini bertujuan
menganalisis pengaruh berbagai konsentrasi Provasoli’s Enriched Seawater (PES) terhadap pertumbuhan mikropropagul K. alvarezii secara in vitro serta menentukan konsentrasi terbaiknya. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan lima ulangan. Hasil penelitian menunjukkan bahwa konsentrasi PES berpengaruh nyata (P<0,05) terhadap bobot mutlak, panjang mutlak, LPBS, dan jumlah talus, tetapi tidak berpengaruh nyata terhadap LPPS. Perlakuan P20 (20 ml L?¹) menghasilkan pertumbuhan terbaik dengan bobot mutlak 0,0551 g, panjang mutlak 1,1 cm, LPBS 6,61% hari?¹, LPPS 5,11% hari?¹, dan 28 talus. Dengan demikian, konsentrasi PES 20 ml L?¹
direkomendasikan sebagai konsentrasi optimum untuk mikropropagasi K. alvarezii | |
| dc.description.abstract | Kappaphycus alvarezii is one of Indonesia’s leading seaweed commodities; however, the availability of high-quality seedlings remains hampered by declining genetic quality, disease, and climate change. Tissue culture offers an alternative for the mass production of high-quality seedlings. This study aims to analyze the effect of various concentrations of Provasoli’s Enriched Seawater (PES) on the in vitro
growth of K. alvarezii micropropagules and to determine the optimal concentration. This study employed a Completely Randomized Design (CRD) with four treatments and five replicates. The results showed that PES concentration had a significant effect (P<0.05) on absolute weight, absolute length, LPBS, and the
number of thalus, but had no significant effect on LPPS. Treatment P20 (20 ml L?¹) produced the best growth with an absolute weight of 0.0551 g, an absolute length of 1.1 cm, LPBS 6.61% day?¹, LPPS of 5.11% day?¹, and 28 shoots. In contrast, P25 (25 mL L?¹). Thus, a PES concentration of 20 mL L?¹ is recommended as the optimal concentration for the micropropagation of K. alvarezii | |
