The research aimed to analyze the relationship between the fraction and porosity of tidal zone sediments in coastal of Teluk Penyu Cilacap. This survey method used sediment core samplers, sediments fractions used sieve method and the porosity used method of Reeve (1986), and analysis used software SPSS20. The results showed that tidal zone sediments in coastal of Teluk Penyu Cilacap were dominated by the fine sand with percentage when high water was higher than low water. Based on mean size diameter, sediment near Serayu river was found medium sand and far was fine sand. Based on linear regression, the relation between sediment fraction and porosity at high water and low water was obtained very weak, but when low water was found in opposite condition to the high water, that the greater of sediment diameter was smaller of porosity. High porosity indicates a wider space between the sediments and allows more decomposing organisms.

Market demand for agar reaches 21.8% per year, but only 13.1% can be met. This is due to the low level of production of G. verrucosa in Indonesia. Utilization of G. verrucosa is still relying on aquaculture from the farm, which causes low production. Cultivation of seaweed with verticulture methods can increase the production of G. verrucosa. Karimunjawa is a potential area for seaweed cultivation. The aim of this study is to determine the effect of different density areas on the growth and production of G. Verrucosa and to determine the best density area for its production in Karimunjawa. This research used G. verrucosa wrapped in a mesh size of 0.5cm with a weight of 50g per pack. Each verticulture strap contains 4 packs and each treatment consists of 9 straps. The treatment was in the form of differences in the planting area of 25x25cm2 (A), 50x50cm2 (B) and 75x75cm2 (C).

The aims of this study were to determine the identity and characters of DNA, and their phylogeny of EHP species from several different locations in Indonesia with specific references to 18S rRNA gene. The EHPs were collected from cultured P.vannamei from Lampung, Pangandaran, Sidoarjo, Banyuwangi, Probolinggo, Blitar, Makassar, and Lombok. Thirteen (13) samples were randomly selected to explore their gene characters through 18S rRNA gene sequencing. The primers used were EHP_F and EHP_1R. Parameter observed were DNA sequencing, nucleotide sequence homology with related available genes in the Gen Bank database, multiple sequence alignment, and reconstruction of genetic relationship trees. DNA sequence homology analysis showed that all samples had 99.89-100% similarity to Indian Enterocytozoon hepatopenaei (Accession Number MH259890.1 and MH260592.1). The alignment results illustrated that all EHP sequences of Indonesian isolates were 100% identical each other. The phylogenetic tree topology provided information that all sample accessions were in the same clade and spread evenly.
