Seaweed is one of the important commodities of fishery products that have economic value. Farmers often use repetitive seeds from the same broodstock so that they have the potential to experience a decline in quality. So it is necessary to do a study of seaweed cultivation using tissue culture seedling with the long line method as an effort to develop seaweed farming. Seaweed (Kappaphycuz alvarezii) has an absolute growth of 138.61 grams, with a growth rate of 4.85%. The growth of seaweed from tissue culture seedlings is better than the growth of conventional seedlings.

Gracilaria verrucosa is one type of seaweed that can be developed into a high-value product. 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 results showed significant differences (P <0.01) between each treatment. The 75x75cm2 area has the best yield on absolute growth, relative growth rate (RGR) and specific growth rate (SGR) of 83.10 ± 4.12g; 3.96 ± 0.20% / day and 2.33 ± 0.07% / day. The best results of G. verrucosa production obtained at an area of 50x50cm2 (5.32 ± 0.26 kg / m2).

Kabupaten Kepulauan Sangihe dengantiga pulau terdepannya memiliki potensi untuk pengembangan budidaya rumput laut (Kappaphycus alvarezii), namun belum tersedia data kondisi perairannya.  Kajian bertujuan untuk mengetahui karakteristik, kesesuaian, dan daya dukung perairan untuk budidaya rumput laut di kawasan pesisir Kabupaten Kepulauan Sangihe.  Data  kondisi perairan yang dikumpulkan berupa lingkungan fisik dan kualitas air.  Analisis dengan weighted linear combinationdalam SIG dilakukan untuk penentuan kesesuaian perairan danbesarnya kapasitas perairan digunakan untuk penentuan daya dukung perairan. Hasil kajian menunjukkan bahwa, karakteristik perairan Kabupaten Kepulauan Sangihe dapat mendukung usaha budidaya rumput laut, namun kedalaman perairan yang relatif dangkal dan adanya alur pelayaran yang menjadi faktor pembatas dalam kesesuaian lahan untuk budidaya rumput laut. Dari 4.839,36 ha kawasan pesisir yang dikaji di Teluk Talengen (Kecamatan Tabukan Tengah), Teluk Manalu (Kecamatan Tabukan Selatan), dan Teluk Dagho dan sekitarnya (Kecamatan Tamako dan Manganitu Selatan) dijumpai kawasan pesisir seluas 181,80 ha yang tergolong sangat sesuai; 852,82 ha yang tergolong cukup sesuai; 3.633,75 ha yang tergolong kurang sesuai; dan 179,99 ha yang tergolong tidak sesuai untuk budidaya rumput laut metoda tali panjang.  Budidaya rumput laut metoda tali panjang di Kabupaten Kepulauan Sangihe dapat dilakukan di Teluk Talengen, Teluk Manalu, dan Teluk Dagho dan sekitarnya  dengan pengembangan kawasan maksimal masing-masing seluas 324; 559; dan 1.171 ha yang dapat digunakan untuk masing-masing 1.296, 2.236, dan 4.684 unit rakit budidaya rumput laut berukuran 50 x 50 m.  Sangihe Archipelago Regency with its three outlying islands has the potential for seaweed farming development (Kappaphycus alvarezii), regrettably reliable water quality data are scarcely available in this region. The study was aimed to determine the characteristics, suitability, and carrying capacity of waters for seaweed farming in the coastal areas of Sangihe Archipelago Regency. The observed environmental quality of coastal waters included physical environment and water quality. A weighted linear combination  in a GIS environment method was applied to determine the suitability of waters and the capacity of coastal water to accommodate the maximum surface area of the farm was used to determine the carrying capacity of waters. The results of the study indicated that the characteristics of waters in Sangihe Archipelago Regency provide suitable environment for seaweed culture, however the relatively shallow waters and the existence of the shipping lanes in the study region can become major limiting factors for seaweed culture and development. Of 4,839.36 hectares of the coastal areas studied in Talengen Bay (Tabukan Tengah Subdistrict), Manalu Bay (South Tabukan Subdistrict), and Dagho Bay and surrounding areas (Tamako and Manganitu Selatan Subdistricts), a total of 181.80 ha were classified as very suitable; 852.82 ha were moderately suitable; 3,633.75 ha were less suitable; and 179.99 ha were not suitable for seaweed long-line culture method. Further analysis showed that seaweed culture of long-line method can be effectively practiced in Talengen Bay, Manalu Bay, and Dagho Bay and surrounding areas with the maximum development areas of 324, 559, and 1,171 ha respectively of which can be used for allocating 1,296, 2,236, and 4,684 culture raft units respectively, with the size of 50 x 50 m per unit.

Budidaya rumput laut banyak dilakukan untuk memenuhi dan meningkatkan produksinya, namun masih banyak kendala, sehingga hasil produksinya belum stabil. Hal ini dapat dilihat dengan pemberian nutrien yang diharapkan akan meningkatkan pertumbuhannya. Tujuan dari penelitian untuk mengetahui pertumbuhan dan kemampuan absorpsi Gracilaria sp. pada media yang mengandung Cu dengan konsentrasi yang berbeda. Metode yang digunakan adalah metode eksperimental laboratoris dengan Rancangan Acak Lengkap (RAL). Perlakuan penambahan konsentrasi Cu pada media pemeliharaan yang terdiri dari 4 tingkat yaitu kontrol (0,036 ppm, sesuai dengan konsentrasi Cu pada air laut), 0.5 ppm, 5 ppm, dan 50 ppm dengan 3 pengulangan. Hasil memperlihatkan bahwa penambahan Cu dengan konsentrasi yang berbeda  memiliki pengaruh nyata (p < 0,05) terhadap pertumbuhan dan kemampuan absorpsi pada Gracilaria sp. Pertumbuhan Gracilaria sp. tertinggi dicapai pada perlakuan A (kontrol) dengan pertambahan berat sebesar 25,34 g dan laju petumbuhan spesifik (SGR) sebesar 0,43%. Nilai pertumbuhan mutlak dan laju pertumbuhan spesifik (SGR) yang didapatkan pada perlakuan B (0,5 ppm) sebesar  -80,37 g dan -1,84% per hari, perlakuan C (5 ppm) sebesar -85,19 g dan -2,02% per hari, dan perlakuan D (50 ppm) sebesar -99,19 g dan -2,47% per hari. Semakin tinggi konsentrasi Cu yang diberikan maka pertumbuhan Gracilaria sp. akan semakin rendah. Seaweed cultivation is done to meet and improve its production, but there are still many obstacles, so its results are not yet stable. This can be seen with the awarding of the nutrients that will hopefully increase its growth. The goal of the research is to know the growth and absorption ability of Gracilaria SP. in medium containing different concentrations of Cu with. The method used is the method of experimental design of randomized Complete laboratories (RAL). Addition of Cu concentration on treatment of media maintenance which consists of 4 levels, namely control (0.036 ppm, according to the concentration of Cu in sea water), 0.5 ppm, 5 ppm and 50 ppm, with three repetitions. The results showed that the addition of Cu with a different concentration of real influence (p < 0.05) towards growth and the ability of absorption on Gracilaria sp. Highest growth of Gracilaria sp. was achieved on A treatment (control) and the increase of the weight of 25.34 g and specific growth rate (SGR) of 0.43%. The absolute growth rate and specific growth rate (SGR) obtained at the treatment B (0.5 ppm) of -80.37g and-1.84% per day, treatment C (5 ppm) of -85.19 g and -2.02% per day, and treatment D (50 ppm) for -99.19 g and -2.47% per day. The higher the concentration of Cu given, then the growth of Gracilaria sp. will be even lower.

ABSTRACT. This study aims: to provide an overview of the development of seaweed cultivation in improving the economy of coastal communities. Based on the results of a theoretical study of various results of research on seaweed cultivation in Indonesia. Some of the things that make seaweed farming activities are in great demand by coastal communities, namely the technical aspects of seaweed farming are relatively easy with a short maintenance time, while from the economic aspect this business is very profitable because of the relatively cheap investment and production costs. The type of seaweed has economic value, namely; Gracilaria sp. Gelidium sp. This can be seen from the behavior of the people in seaweed management which still overrides the surrounding environmental factors. This certainly contradicts the concept of integrated coastal areas.ABSTRAK. Penelitian ini bertujuan: memberikan gambaran tentang perkembangan budidaya rumput laut dalam meningkatkan perekonomian masyarakat pesisir. Berdasarkan hasil kajian teori dari berbagai hasil penelitian tentang budidaya rumput laut yang ada di Indonesia. Beberapa hal yang membuat kegiatan budidaya rumput laut sangat diminati oleh para masyarakat pesisir yaitu aspek teknis usaha budidaya rumput laut yang relative mudah dengan waktu pemeliharaan singkat, sedangkan dari aspek ekonomi usaha ini sangat menguntungkan karena biaya investasi dan produksi yang relatif murah. Adapun jenis rumput laut memiliki nilai ekonomi yaitu; Gracilaria sp, Gelidium sp, Sargassum sp , Eucheuma cottonii,dan Euxheuma spinosum., Maka dapat disimpulkan hasil dari kajian ini bahwaterdapat kecenderungan masyarakat dalam menanam rumput laut masih jauh dari konsep pengelolaan yang berkelanjutan. Hal tersebut bisa dilihat dari perilaku masyarakat dalam pengelolaan rumput laut yang masih mengesampingkan faktor lingkungan sekitar. Hal tersebut tentu bertentangan dengan konsep pelestarian wilayah pesisir secara terpadu.
