Abstract

Rumput laut Gracilaria verrucosa asal Kabupaten Sinjai memiliki kualitas paling rendah di antara semua sentra produksi Gracilaria sp. di Sulawesi Selatan. Hal ini salah satunya dikarenakan oleh bibit yang buruk. Penyediaan benih rumput laut yang berkualitas dapat dilakukan salah satunya dengan penggunaan bibit hasil kultur jaringan. Perbanyakan bibit Gracilaria verucosa dapat dilakukan dengan menggunakan metode tali panjang long line maupun metode sebar (broadcast) di tambak. Tujuan penelitian ini untuk mengetahui respons pertumbuhan, kandungan agar, dan kekuatan gel (gel strength) dari bibit G. verucosa hasil kultur jaringan di tambak Kabupaten Sinjai. Metode penelitian ini adalah eksperimen dengan dua perlakuan dan tiga ulangan yaitu perlakuan A (bibit kultur jaringan) dan B (bibit lokal) dengan berat awal masing-masing 10 kg. Pemeliharaan bibit dengan metode sebar dilakukan selama 30 hari. Hasil analisis ragam menunjukkan bahwa laju pertumbuhan harian (DGR), kandungan agar dan gel strength bibit kultur jaringan dan bibit lokal menunjukkan perbedaan yang nyata (P<0,05). Secara kuantitas hasil produksi bibit hasil kultur jaringan memiliki pertumbuhan yang lebih tinggi daripada bibit lokal dengan berat akhir bibit 44,3 ± 4,16 kg hasil kultur jaringan dan 33,0 ± 4,35 kg lokal dengan DGR 4,97% bobot/hari (kultur jaringan) dan 3,90% bobot/hari (lokal). Secara kualitas bibit hasil kultur jaringan lebih baik dari bibit lokal, ditunjukkan dengan persentase kandungan agar bibit hasil kultur jaringan lebih tinggi daripada bibit lokal dengan rendemen agar 22,19 ± 2,45% (kultur jaringan) dan 16,50 ± 0,96% (lokal), sementara gel strength sebesar 204,20 ± 0,45 g/cm2 (hasil kultur jaringan) dan 128,10 ± 1,55 g/cm2 (bibit lokal).Seaweed Gracilaria verrucosa from Sinjai Regency has the lowest quality among all Gracilaria sp. Production centers in South Sulawesi due to the low quality of the seed. The seed quality can be improved using seed selection, followed by tissue-culture methods. Long-line and broadcast methods in brackishwater ponds are the efficient seaweed culture techniques to multiply the number of Gracilaria verrucosa seeds. This research was aimed to determine growth performance, gel content, and gel strength of seeds produced from tissue-culture and local seaweed farming. The experiment consisted of two treatments: treatment A (cells culture seed) and B (local seed) with the initial weight of 10 kg, each has three replicates. Both seeds were stocked and reared in the ponds using the broadcast method for 30 days. The results of DGR, gel content and gel strength showed a significant difference between tissue-cultured and local seeds (P<0.05). The tissue-cultured seed had better growth than the local seed with 4.97% mass/day for tissue-cultured seed and 3.90 mass/day for local seed. The tissue-culture seed also had better quality in agar content and gel strength. The agar content of tissue-cultured was 22.19 ± 2.45% and the local was 16.50 ± 0.96%. The gel strength of tissue-culture was 204.20 ± 0.45 g/cm2, and the local was 128.10 ± 1.55 g/cm2.

Abstract

Cooperative capital does not diminish and obscure the understanding of cooperatives themselves, but in reality that any association that is engaged in the business, the capital has a very important position, and therefore the board is required to be more professional in carrying out their duties and responsibilities in managing the cooperative, with a good board skills will further enhance the trust and participation of members in exercising their rights and obligations. This research was conducted in the Village Unit Cooperatives Farmers Fresh Merangin District, which aims to determine the factors that affect the growth of capital               at Farmers Fresh Village Unit Cooperatives.This research is a qualitative descriptive study, in which researchers want to describe the situation and condition of the factors that influence the growth of capital in cooperatives Fresh Farmers Cooperative. The research was conducted in KUD Tani Fresh by the number of subjects or informants are 4 people are: chairman, secretary, treasurer and one of the representatives of the employees.The findings suggest that the factors that affect the cooperative capital partumbuhan education level, and management level pendapatn cooperative, then the interview is happening in the field is the development of co-operative capital is also influenced by the credit crunch and electricity fee, and at some point in the event the price of fruit is too cheap or dropped so that could affect the development        of            co-operative         capital.It is suggested that the entire board of the cooperative can pay attention to the factors that affect the cooperative capital, so the development of co-operative capital to develop properly, then the board members or the cooperative and all parties associated with lending to the cooperative to be able to cooperate in the settlement perkreditannya so that no bad debts.Keywords: Factors affecting the growth of capital

In accordance with the societal perception regarding the condition of eastern regions of Indonesia that are categorized as underdeveloped regions, it is of requirement for local government to alternate such paradigm. It might be by optimizing the potentialities that entail West Manggarai, particularly on tourism sector, in addition to increase the revenue. Therefore this research was intended to: (1) describe the efforts of developing the tourism potentiality in developing the locally-generated revenue in West Manggarai; (2) analyze the barriers faced by the local government in developing the tourism potentiality; (3) formulate the possible solutions for local government to overcome the barriers. Moreover, this research accommodated descriptively qualitative research design in whichthis research was to systematically and conscientiously provide a vision of actual facts and characteristics of particular population. In addition, it aimed to solve the actual issues and collect the data. Furthermore, the data were originally collected from observation, interview, and documentation. In fact, the informants recruited included the secretary of Department of Tourism and Culture, the head of field development tour-guide (1 person), and tourist (1 person) of West Manggarai. Alluding to the research that had been piloted,there were some results as being explicated as follows: (1) the strategies of localgovernment in developing the revenue by means of developing the tourism potentiality had been implemented and inserted into the strategic plan, but they had not been maximally successful yet; (2) the barriers faced in developing the tourism potentiality comprised societal factor, lack of quality regarding human resource, limited budgets, ineffectiveness of supporting facilities, lack of collaboration with private parties, the sharp competition ofmarket, and the unobtainability of tourism promotion facilities, such as websites; and (3) the possible solutions to overcome the barriers were by: establishing aware group of tourism, upgrading the quality of human resource, optimizing the expenditures and revenues, developing the supporting facilities, strengthening the coordination of each department, upgrading the quality of products, and optimizing the promotion facilities.Keywords: The Strategies, Local Government, Tourism Potentiality.
