Abstract

Fisheries business actors in Indonesia have different backgrounds in knowledge, education, social and psychology. This diversity creates obstacles to the application of traceability of Indonesian fishery products, so that they lack competitiveness in the international market. The research aims to find some simple schemes that are easily understood by Indonesian fisheries businesses to implement traceability extensively. Descriptive research method. Data were obtained from terrestrial surveys and interviews with business actors spread across various fishery centers in East Java, since 2015 until now. The results of the observations are arranged in a simple matrix to find the suitability of the behavior of the design business actors at each observation point. The results of the analysis show that: the commitment and consistency of the fisheries businessman is largely determined by the factors of knowledge, education, social, and psychology respectively. Knowledge is the best aspect of power to create the drafting of search data; because this aspect turns out to be 'forced' to 'understand' by all parties doing business. The design of the accuracy of the meeting point of upstream search data with downstream traceability can be realized through the dissemination of knowledge in a simple and applicable manner continuously, extending to all lines and implanted to consumers from an early age. The weak implementation of traceability in Indonesia is caused by the lack of consumer understanding of the importance of search data; which has a strong impact on suppliers to "ignore" the implementation of traceability for local products.

Abstract

Sea lobster is a commodity that has high value in both national and international markets. Globally, the demand for sea lobster is increasing by about 15% per year. During growth, lobsters undergo a moulting process. Moulting/ecdysis is a very important process in the life cycle of arthropods (including decapods) because shell release is a must for growth and metamorphosis. In improving and assisting the molting process in lobsters, it is assisted by the provision of additional calcium from egg shells. Egg shells contain 94% calcium carbonate, 1% calcium phosphate, 1% magnesium carbonate and 4% organic compounds. In this study, an experiment was conducted on the addition of feed with a mixture of egg shells to support post-moulting optimization and supplement calcium requirements for lobster larvae. The percentage of egg shells as treatment, namely treatment A (0%), B (5%), C (10%), and D (15%) of the total feed to be made for sea lobster. Maintenance is carried out in a controlled tub, for four months. The highest specific growth obtained in this treatment was treatment A (0.06-0.21%) and the lowest was treatment D (-0.02%)-(-0.37%). Furthermore, the highest survival rate was obtained in treatment A (66.7%) and the lowest in treatment D (33.3%), the highest number of molting lobsters was in treatment A (77.8%) and the lowest was treatment D (33.3%). This shows that the addition of eggshell flour to moist lobster feed has not had a significant effect. For further development, it is necessary to research related to the use of additional ingredients in moist feed for lobster.

Abstract

GMO is a product of biotechnology through genetic engineering techniques. This can be done to increase food availability and reduce production costs, especially by manipulating the genes and chromosomes of cultivated species. In invertebrates such as shrimp, the application of gene transfer is still limited to the recognition and expression of foreign genes and focuses on increasing disease resistance. Among several gene transfer methods (microinjection, electroporation and transfection), transfection method is the most effective method to be applied to shrimp. It is characterized by high hatching data and is not toxic. In addition, the use of GMO in aquaculture is a highly controversial issue due to many environmental and health issues. This journal will discuss gene manipulation by means of gene transfer to improve shrimp culture.

Abstract

The potential and development of alternative livelihoods for fishermen households in marine conservation areas must be relevant to or refer to the context of contextual technical considerations (locality), and not a deduction or bottom-up policies derivation so that they can grow and develop (facilitating) local fishermen's households in production activities that are complementary to increasing the spirit of the locality, community harmonious with natural resoureces and welfare through the opening of new economic spaces that can be accessed and controlled by the local community themselves. This type of research is qualitative with a case study approach. Data was collected through direct observation and in-depth interviews with some informants. There are 30 fisherman’s household which is used as primary data source informants. Qualitative analysis based on technical variables, namely community interest, availability of local raw materials/natural resources, availability of labor and market opportunities through content analysis from compilation of interview results through snowball technique with reference to triangulation principle. While quantitative data analysis is carried out with business feasibility indicators for new alternative types of livelihoods that can be applied to fishermen households, namely B/C Ratio indicators, Return Of Investment (ROI), and Payback Period (PP). Research result show that based on the analysis of technical variables, the potential alternative livelihoods carried out by fishermen households are seaweed aquaculture, floating net cage aquaculture, processed fishery products, coconut and household scale chicken and duck farming. The B/C ratio value of these businesses is > 1 with very profitable criteria to do.

Abstract

Indonesia has the potential for the beauty of its islands and coasts which are well known to foreign countries. Not only beautiful beaches, also stretches of coral reefs with hundreds of marine species, mangrove forests with their ecosystems are a panorama that can be found from Sabang to Maraoke. It is estimated that more than 21 marine tourism sites have been developed and become destinations for world and local tourists, in addition to locations that are still managed by the community. Foreign exchange contributions from the tourism sector continued to increase in 2018, the tourism sector's foreign exchange reached IDR 229.5 trillion, an increase of 15.4 percent on an annual basis. This study aims to describe the condition of marine tourism potential in South Sulawesi and its impact on local communities living around tourist sites and the development needed to improve the welfare of local communities. The research locations were on Lemo Beach, East Luwu Regency, Bira Bulukumba Beach and Makassar Lantebong Mangrove Tourism, taking 100 respondents. The research method is qualitative and analyzed descriptively by correlation and using Likers to assess its impact on people's welfare. The results of the study illustrate that in general, the role of the government, both local and provincial, is still needed, especially in environmental hygiene facilities, order for traders. The social impact on people's behavior shows that there is a change in the ability to communicate and interact more openly with a value of 1634. The economic impact shows a very large regional value due to the opening of new job opportunities which are a source of income for the local community with a value of 2250.
