“…However, it is suspected that if the current is too strong or more than 0.5 m/sec, the seaweed growth tends to be detrimental. The seaweed specific growth rate in the longline method tends to be higher and almost similar to [15] at 2.26% -3.47%/day. This growth can be higher, if there are no epiphytic organisms attacking the seaweed surface (host), such as red filamentous algae (Epiphitic Filamentous Algae/EFA) from Melanothamnus sp.…”

The seaweed culture activities are relatively new and only few people perform them in Lingga District. Specifically, Kappaphycus striatum has recently been cultured for the last three culture periods. This condition causes the seaweed culturists have no appropriate data associated with a proper culture method, following the water characteristics around the culture area. A study regarding the different culture methods on the growth performance of K. striatum in Pelakak Village waters, Lingga District, Riau Islands has never been reported. This study aimed to determine the effect of different culture methods on the growth performance of Kappaphycus striatum seaweed. This study used a completely randomized block design with three treatments and three replications, namely bottom method (P1), off-bottom (P2), and longline method (P3). There were 351 seaweed seeds with 100 g weight per each seed, that are placed in nine culture plots. The culture plot was constructed as a 4 m × 1.5 m square with wooden stakes at both ends and polyethylene ropes installed at a distance of 0.5 m. Each rope stretch was tied at 0.3 m distance for seed planting. Parameters observed in this study were absolute growth rate, specific growth rate, and production rate of the seaweed. The results showed that the absolute growth rate, specific growth rate, and production rate were affected by the culture method (p<0.05). The seaweed group reared in a longline method (P3) obtained the best results, compared to other methods, at 2.34% per day for specific growth rate and 245.7 g/m2 for production rate. Therefore, the longline method can be applied in the Pelakak Village waters, Lingga District.

“…This is characterized by relatively slow or stunted growth, as well as seaweed's susceptibility to iceice disease infection. The potential cause of this condition is the repeated use of cultivated seeds (Parenrengi et al, 2017;Loura Pandelaki, 2012).…”

Pengelolaan Kegiatan Budidaya Rumput Laut Oleh Pembudidaya Di Perairan Labuhan Sangoro, Teluk Saleh, Kabupaten Sumbawa

Nusa Tenggara Barat merupakan salah satu produsen terbesar rumput laut di Indonesia. Lokasi budidaya rumput laut dapat ditemukan di perairan Pulau Lombok maupun Pulau Sumbawa. Kegiatan budidaya ini telah menjadi salah satu mata pencaharian, bahkan mata pencaharian utama bagi masyarakat pesisir. Selain itu, pemerintan NTB turut mendorong pengembangan produksi rumput laut dalam program PIJAR (sapi, jagung, dan rumput laut). Teluk Saleh, sebagai salah satu teluk yang telah dikenal sebagai kawasan megabiodiversity, telah lama dimanfaatkan sebagai kawasan kegiatan budidaya rumput laut. Namun, baru-baru ini, terdapat permasalahan terkait penyakit rumput laut yang menimbulkan kerugian bagi para pembudidaya. Tepatnya, kasus penyakit tersebut secara signifikan muncul di salah satu kawasan perairan di Teluk Saleh, yaitu perairan Labuhan Sangoro. Berbagai prediksi muncul terkait dengan timbulnya serta dampak dari kejadian penyakit rumput laut. Namun belum dapat dikonfirmasi secara tepat. Oleh karena itu, diperlukan penelitian mengenai kegiatan pengelolaan budidaya rumput laut oleh para pembudidaya di perairan Labuhan Sangoro mengenai kegiatan budidaya rumput laut di kawasan tersebut. Adapun metode yang digunakan dalam penelitian ini yaitu wawancara menggunakan kuesioner (data primer). Responden dipilih secara purposive yaitu petani budidaya rumput laut dan jumlah responden sebanyak petani yang masih aktif membudidayakan rumput laut. Data yang diperoleh selanjutnya dianalisis secara deskriptif kualitatif. Hasil penelitian ini menunjukkan bahwa responden memiliki pengetahuan yang baik dalam pengelolaan budidaya rumput laut yang mereka lakukan, dan memiliki kecenderungan untuk tetap melakukan kegiatan budidaya rumput laut walaupun terdapat kendala-kendala yang sering mereka hadapi terkait dengan faktor finansial dan faktor alam. Namun tetap dibutuhkan edukasi terkait penyebab-penyebab potensial munculnya penyakit rumput laut serta upaya penanganannya.

“…In this study, the score index (between one and four) was utilized, where one indicates a score with a not-suitable category, and four is very suitable [14] and [17]. The distribution of the score of the level of suitability of each parameter refers to [18], Decree of the State Minister of Environment Number 51 of 2004, concerning Seawater Quality Standards [11], [15] and [19]. Furthermore, in IFMR-713, the weight score was determined based on the level of parameter importance in influencing the suitability of seaweed cultivation.…”

Seaweed is an excellent product for cultivation in Indonesia therefore the expansion of seaweed aquaculture is crucial to be supported by the availability of data and accurate information. The Republic of Indonesia’s Fishery Management Region-713 (IFMR-713) has the potential for the development of seaweed cultivation. This study aims to conduct a spatial analysis of suitability for the development of seaweed cultivation using numerical models data based on multi-criteria evolution (MCE) in the IFMR-713. The primary data used for the analysis are (1) physical geographical parameters (includes: bathymetry, wave height, and current) and (2) water quality parameters (contains: temperature, salinity, pH, phosphate, and nitrate). The potential seaweed cultivation area in IFMR-713 is 63,125 km2 (13.12%) of the total area in IFMR-713 (481,300 km2). We also found that the local community utilized only a minor part of the very suitable area categorized for cultivating seaweed (based on data and information from each Local Government), so there is still an opportunity to develop the utilization into the very appropriate category. However, it is recommended that its use should be based on environmental methods and adapted to the coastal spatial plan to be used as an essential foundation to support the application of ecosystem-based fisheries.
