Judul: Improving youth’s role in fisheries and marine affair development in Sukabumi Regency
Abstrak: Fisheries and marine development contributes to the national income, employment, foreign exchange reserves, and acceleration of remote islands development acceleration. Politically, the development of fisheries and marine affair development is implementation of Indonesian development for the unity of the nation. Human resource is one of the main constraints in optimizing the role of marine and fisheries resources. The study is aimed at formulating policies in which youth’s roles in fisheries and marine affair development could be improved. Specifically, the objectives of the study are: (1) to identify and to assess forms of youth’s roles in fisheries and marine affair development; (2) to assess and to synthesize factors affecting youth’s roles in fisheries and marine affair sector; (3) to determine policy variables affecting youth’s roles in fisheries and marine affair development; and (4) to formulate public policy aimed at improving youth’s roles in fisheries and marine affair development. This study was conducted in Sukabumi Regency and a structural equation modeling (SEM) was applied. Types of youth’s roles in fisheries and marine affair are planning, fisheries production, monitoring and evaluation of use of fisheries and marine resources, and fisheries institutions. Youth plays their role most in fisheries production, especially as the labor because it is relatively the simplest type of role they can implement. Other youth’s roles, however, should be promoted continuously to optimize their overall roles. Expanding labor employment is the priority agenda of the government, but the government has to boost the other types of youth’s roles in terms of planning, monitoring and evaluation, and fisheries institutions. Factors affecting youth’s roles in fisheries and marine affair development are public policy, youth entrepreneurship, social capital ownership, and resources possession. Among the most influencing variables of public policy are extension intensity and credit provision. The factors affecting youth’s roles in fisheries and marine affair development are correlated each other. It indicates that public policy will be effective if it is implemented simultaneously with other policies.

Judul: Fisheries Subsector Analysis in Indramayu Regency Regional Development.
Abstrak: Indramayu Regency has a great potential in renewable fisheries. It is expected that this fisheries subsector continues to grow and become a strategic subsector in Indramayu regional development. The objectives of this research were: (1) to identify the role of the fisheries subsector in the economy of the region and its links with other sectors in Indramayu regency, (2) to learn about the level of development of the regional development of fisheries subsector in Indramayu Regency based on the conditions of facilities and infrastructure, and (3) to find out the perception of stakeholders in determining development priorities for the fisheries subsector as well as to formulate a strategic direction in the development of the fisheries subsector in Indramayu regency. The analysis methods used were of Input-Output (I-O) analysis, hierarchical analysis of regional development (Skalogram Method), Analytic Hierarchy Process (AHP), and the combination of AHP and SWOT analysis (A'WOT). Based on the analysis, the fisheries subsector had a relatively low sectoral relationship. The result of direct forward linkage (DFLi), direct backward linkage (DBLj), Index deployment value (backward linkages effect ratio) and degree of sensitivity index value (forward linkages effect ratio) were below average. The result of multiplier effect output of fisheries, multiplier effect of fisheries gross value added, and multiplier effect of fisheries were revenue relatively low compared to other sectors. The fisheries subsector has the potential to be developed through enhancing linkages between sectors with industry excluding oil/gas sector and wholesale and retail trade sector. Schallogram analysis showed that the districts on hierarchy III were considered feasible to do the development since they were supported by the number of Farmer Households of culture amounting to 2,952 people (68%) of the total 4,344 people and 26,936 Fishermen Households (72%) of the total 37,425 people residing in the coastal area with the value of Human Development Index under 70.
