PERTUMBUHAN Kappaphycus alvarezii YANG TERKONTAMINASI EPIFIT DI PERAIRAN SUMENEP

Apri Arisandi, Akhmad Farid, Sri Rokhmaniati

Abstract


Peningkatan suhu musim kemarau yang relatif tinggi memicu peningkatan kontaminasi penyakit dan epifit di perairan Sumenep, sehingga mempengaruhi rata-rata pertumbuhan harian Kappaphycus alvarezii.  Penelitian ini bertujuan untuk mengetahui dampak kontaminasi epifit, terhadap pertumbuhan K. alvarezii di perairan Sumenep.  Penelitian dilakukan menggunakan metode budidaya dalam rakit apung, thallus K. alvarezii yang terkontaminasi epifit diamati serta dihitung rata-rata pertumbuhan hariannya.  Hasil penelitian menunjukkan,kontaminasi epifitmenyebabkanrata-rata pertumbuhan harian K. alvareziimenurunhingga-0,07% sampai 0,92%, oleh karena itu K. alvareziiyang telah terkontaminasiharus segera dipanen.

Kata Kunci: epifit, pertumbuhan, K. alvarezii
