Analysis of seaweed cultivation business in Ped village, Nusa Penida district, Klungkung regency
Seaweed is one of the potential marine biological resources which functions as a source of income for the government and community. Ped village located in Nusa Penida has a relatively wide seaweed cultivation area covering around 32 ha, with the number of farmers being 325 families. The kinds of seaweed suitable to be cultivated using the off-bottom method in Nusa Penida is Euchema spinosum and euchema cottonii. Seaweed cultivation is very easy, requiring no fertilizers and pesticides as in rice plantation. Another advantage is that it can be planted throughout the year, and it has a short harvest age, which is about 42 days. The quality of seaweed is largely influenced by the type of seeds, the age of harvest, and, most importantly, the drying process. Drying is done using the following method: the seaweed is placed on a tarp put on the ground and exposed it to the sun. As a consequence, the amount of dirt contained in the dried seaweed is still high, leading to its low price. This research was conducted using survey method. The data collected consisted of primary and secondary data. Primary data relating to socioeconomic and business circumstances are collected through interviews and questionnaires. Secondary data were obtained from the Nusa Penida Sub-district, and the Central Bureau of Statistics of Klungkung Regency, as well as other references related to the study. The results of this study showed that the cultivation of seaweed using off-bottom method was quite effective, RCR = 1.29, meaning that such method was profitable and reasonably feasible. The net income derived from an area of 4 acres was Rp. 1.800.000 per period. This opens up business and employment opportunities for the surrounding community, although this income is still highly dependent on the national tend-to-fluctuate market price of dried seaweed.
