ABSTRAK

Salah satu jenis rumput laut yang dibudidayakan dan memiliki nilai ekonomis tinggi adalah Eucheuma cottoni. Untuk melakukan penyerapan terhadap cahaya pada tingkat kedalaman yang berbeda E. cottonii menggunakan berbagai macam pigmen diantaranya klorofil-a dan fikoeritrin. Kandungan pigmen yang berbeda pada berbagai tingkat kedalaman ini diperkirakan akan berpengaruh terhadap produk utama hasil fotosintesis pada E. cottonii yaitu karaginan. Penelitian ini bertujuan untuk mengetahui kandungan klorofil-a dan karaginan rumput laut jenis E. cottoni yang ditanam pada kedalaman yang berbeda. Metode yang digunakan untuk penanaman bibit adalah metode rakit apung. Pemanenan dilakukan setelah 45 hari masa penanaman. Selanjutnya dilakukan analisis laboratorium terkait kandungan klorofil-a dan karaginan. Hasil penelitian ini didapatkan bahwa kedalaman memberikan pengaruh yang nyata tehadap kandungan klorofil-a dan karaginan pada E cottonii. Kandungan klorofil-a dan karaginan tertinggi pada kedalaman 20 cm dengan kandungan klorofil-a sebesar 10484 mgg dan karaginan sebesar 6843 .


ABSTRACT

One of seaweed type that is cultivated and has high economic value is Eucheuma cottonii. To absorp light at different depths E. cottonii using a variety of pigments including chlorophyll-a and phycoerythrin. The content of the different pigments at different depth are expected to affect the main products of photosynthesis in E. cottonii named carrageenan. This study aims to determine the content of chlorophyll-a and carrageenan of E. cottonii that has been planted at different depths. The method that was used for seedlings planting is floating method. Harvesting was done 45 days after planting. And then was analysed content of chlorophyll-a and carrageenan. The results of this study is the depth of significant effect for content of chlorophyll-a and carrageenan in E. cottonii. The thighest content of chlorophyll-a and carrageenan at a depth of 20 cm. For the chlorophyll-a content was 104.84 mgg and carrageenan was 68.43
