Seaweed Culture

Seaweed farming activity is now facing some problems caused by pest fish herbivore and ice-ice disease. To solve those and improve our seaweed quality, seaweed production management requires some ecological technique improvements. The purpose of this study was to determine the functions of seaweed H. durvillaei for improving the production of the seaweed E. spinosum in the coastal area of Geger Beach, Peminge Village, South Kuta subdistrict, Badung regency, Bali. The measured data includes parameter of weight, length and water quality. Data was measured every 10 days for up to 40 days. The best growth result was shown by the model of E. spinosum that were fenced by H. durvillaei of 456 g for E. spinosum. H. durvillaei showed good impact on increasing the production of E. spinosum up to 68.7% compared to the control. Water quality conditions on seaweed culture was good with temperature ranged from 27.7 to 30.1°C, salinity from 30 to 32.3 ppt, DO from 3.9 to 5.5 ppm, pH from 7.9 to 8.4, current 0.1 to 0.2 m/s, and clearness of 100%.

The objective of this research was to evaluate the suitability of several environment factors and water quality parameters for development of seaweed culture in Kampung Sakabu.  The research was conducted through observation at three stations while protection factor and bottom substrate of waters were observed visually. Water quality parameters including pH, salinity, current rate, temperature were measured in situ and the compared to Standard Water Quality Citeria by Bakosurtanal 1996.  Research results were divided into three suitability categories namely 1) very suitable, 2) suitable, and 3) less suitable.  In general, environmental condition and water quatily in Kampung Sakabu were categorized as suitable to very suitable. This results indicated that         waters of Kampung Sakabu was very potential for development of seaweed culture. Keywords:  Kampung Sakabu, seaweeds, area suitability, water quality

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.

The latest trends in tourism indicate the emergence of a new segment of visitors looking for accommodation in private residences. The increase in second-home residents has led to efforts to improve knowledge of the preferences of this new type of tourist in those destinations where their presence is considerable. As one of the key variables affecting the choice of residential tourists is the environmental quality of the area, this paper focuses on testing for the existence of an inverse correlation between the loss of coastal water transparency, viewed as a measure of environmental quality, and beach aesthetics in Santa Ponça Bay, a Mallorcan coastal area containing two urban beach zones of intensive recreational use, where the proportion of second-home residents is high. The results show that the willingness to pay for improvements in water transparency diminishes in a non-linear way when transparency deteriorates, resulting in no statistically significant differences between first- and second-home residents.
