Abstract
The main causes of ice-ice disease that seaweed production will decline. Bacterial infections occur due to fluctuations in climate change resulted in a decrease in water quality resulting in the durability of seaweed. When seaweed stress will facilitate pathogen infection. Disease pathogens cause damage to internal organs. The spread of bacterial disease in seaweed is generally very fast and can lead to death, so that the loss caused by this disease is quite large. Ice-ice disease occurrence is seasonal and contagious, so the impact on the selling price low. The results showed that there are two types of pathogenic bacteria that can potentially cause disease in which bacteria Vibrio alginoliticus and Pseudomonas aeruginosa. Climate change affects the spatial distribution of micro seaweed bacterial pathogens.

Summary
Rumput laut merupakan salah satu komoditi ekspor yang potensial untuk dikembangkan. Saat ini Indonesia masih merupakan salah satu negara eksportir penting di Asia karena rumput laut tumbuh dan tersebar hampir diseluruh perairan Indonesia. Rumput laut yang ada di perairan Indonesia tidak semua bermanfaat bagi manusia. Namun permasalahan yang sering timbul pada usaha budidaya rumput laut yaitu adanya serangan penyakit iceice. Pengendalian penyakit ice-ice pada rumput laut di Indonesia belum tertangani dengan baik yang berakibat penurunan produksi rumput laut. Perlu diupayakan pencegahan dan pengobatan terhadap penyakit rumput laut secara hati-hati dan teliti agar tidak menimbulkan kerugian pada produksi rumput laut. Berdasarkan permasalahan diatas, perlu adanya kajian lebih lanjut untuk mengetahui secara pasti jenis bakteri yang ditemukan pada rumput laut yang terserang penyakit ice-ice sebagai acuan pengendalian dan pengobatan selanjutnya
