Publisher : Faculty of Marine and Fisheries, Universitas Syiah Kuala

NPK is a type of fertilizer that plays a role in increasing growth and survival in plants such as seaweed. This study aims to determine the effect of different NPK fertilizer doses on the growth rate of seaweed (Caulerpa racemosa), and to determine which NPK fertilizer dosage has the best effect on the growth rate of C. racemosa. Research begins with collecting samples of seaweed in coastal waters. Ternate Island District Kastela, and the cultivation process is carried out on Jalan Jan, Tabona Village, South Ternate City. The time of the research was two months from August to October, 2020. This study used 12 units of cool box in the form of cork with a size of 90 x 30 cm, which is used as a container for maintaining of C. racemosa. In each treatment using a seed weight of 50 grams. The NPK fertilizer dosage treatment tested was 4 doses, with 3 replications, namely: treatment A: 40 ml NPK fertilizer; B: 60 ml NPK fertilizer; C: 80 ml NPK fertilizer; D: 0 ml NPK fertilizer (control). Research containers using random placement. The design used was a completely randomized design (CRD), using analysis of variance (ANOVA). The results obtained showed that NPK fertilizer with different doses the effect is not significantly different on the growth rate of C. racemosa with the highest average growth rate in treatment C amounting to 8.725%, followed by treatment B of 8.178%, treatment A of 7.761%, and the lowest was treatment D of 6.519%.Keywords:NPKSeaweedCaulerpa racemosaGrowth rate

The potential of seaweed S. duplicatum is quite abundant in this area, but efforts to develop its cultivation have not been developed until now. The reason is that there is no information related to the existence of this type of seaweed in North Maluku, especially in the city of Ternate. To recognize and utilize the existing potential, it is necessary to develop its cultivation. The objectives of this research are: to determine the effect of different thallus weights on the growth of S. duplicatum seaweed and determine the weight of the thallus which has the best effect on the growth of seaweed S.. dupicatum . The collection of seaweed S. duplicatum seedlings was carried out naturally in Sasa waters, at a depth of about 1 meter. The seeds obtained are then put into a container (plastic bag). After that, it is taken and then taken to the laboratory to be weighed. The weight of the thallus that has been weighed is then tied to each spanning rope which is placed into each container according to its thallus weight, namely thallus weights of 50, 70 and 90 grams. The container used for maintenance was fiber tub with a container length of 90 cm, width of 30 cm, 9 (nine) units. The results showed that the thallus weight of 90 grams gave the best results for the absolute weight growth of 101.66 grams and the thallus 50 grams gave the best results for the relative growth rate of 1.437%.

The seaweed Caulerpa racemosa cultivation unit used in this study was the off-bottom method measuring 5 m x 10 m. This size can contain 5 stretch ropes/risers with a length of 10 m and a distance of 1 m between the stretch ropes/risers. Each stretch / riser line contains about 45 seed clump points with a distance between clumps of 15 cm. The observation procedure for the growth of Caulerpa racemosa seaweed was carried out by weighing the seaweed seeds in each stretch/riser rope. The weight of seed that is weighed is the weight of seeds at the time of planting and the weight of seaweed at harvest.The results showed that the average growth rate of seaweed Caulerpa racemosa was varied for each rope. In ris 1 rope, the average absolute weight growth reached 100.88 grams, ropes 113.33 grams, ris rope 3, 88.00 grams, rope ris 4, 116.00 grams, and rope ris 5, amounting to 113, 33 grams. In general, the highest growth in absolute weight was found in the fourth rope, which was 116.00 grams.

This study was conducted with the aim of knowing the composition of gastropod species that live in the seagrass area of Tafaga and Figur coastal waters, Moti Island and to determine the structure of the gastropod community which includes density, diversity, dominance and species evenness. The sampling technique was carried out using the 50x50 m block area method. The composition of gastropod species found in coastal waters of Tafaga (station 1) was 6 species and coastal waters of Figure (station 2) were 17 species. The highest density of gastropod species in station 1 was found in the Nassarius pullus species and the lowest in the Naria erosa species. Meanwhile, in the station 2, the highest density of gastropod species was also found in the Nassarius pullus species and the lowest in the Strombus lentiginosus species. The diversity of gastropod species at station 1 is low and there are species that dominate and the distribution of species is quite even. While at station 2 the species diversity is moderate and no species dominates and the species distribution is evenly distributed.

. Seagrass ecosystem is one of the coastal ecosystems that can provide food supply and improve the living standards of coastal residents. The objectives of the study were to determine the composition of the seagrass species on Toduku Island, to determine the composition of the seagrass biota species, to determine the community structure of seagrass species and associated biota including species diversity, species dominance and species density and to determine the interaction pattern of the utilization of seagrass fisheries resources by the community around Toduku Island. . The method used is field observation and Participatory Rural Appraisal (PRA). The composition of seagrass species in Toduku Island are Enhalus acoroides, Thalassia hemprichii, Halophila minor, Cymodocea rotundata, Halodule pinifolio, and Syringodium isoetifolium. The composition of the biota that inhabits the seagrass beds of Toduku Island consists of fish, crabs and macrozoobenthos (Holothuroidea, Echinoidea, Asteroidea, gastropods, bivalves). The diversity of seagrass and biota species is moderate, there is no dominant species and the distribution of each species is very even. The pattern of interaction in the use of seagrass resources has been patterned for generations. The forms of utilization activities carried out by the community include taking mollusks (snails, clams), echinodes (sea cucumbers, sea urchins), catching fish and crabs.
