Abstrak: Hunting and stabbing cetaceans and other big fishes such as manta rays and sharks has become the cultural core for fishing community of Lamalera. Changing in cultural core can occur promoted by technological change as one of driven factors. This research has purposes to analysis the persistence of hunting and stabbing activities of cetaceans and big fishes as cultural core of Lamalera’s community and the influences of marine conservation policy on the existing social system. The results show that the change of production technology in Lamalera’s community was initiated by motorization introduced by FAO. This change has created a new system of production economy in Lamalera that is trawl system which is completely different from the traditional system that is stabbing system. Simultaneously it has determined other systems in society such as distribution and exchange pattern, social institutions, religion system and norms. In addition, Lamalera’s community is also acquainted by marine conservation discourses introduced by an international NGO for conservation. Both external factors have deteriorated the traditional economic management of Lamalera’s community which was initially based on the cultural core. Eventually these changes create polarization and new social classes in the community and eliminate social assurance for poor people, elders, widows and orphans.

Judul: Perubahan Moda Produksi dan Potensi Konflik pada Kalangan Nelayan (Studi Kasus pada Nelayan Bugis Sape, Kabupaten Bima, Nusa Tenggara Barat)
Abstrak: Fisheries modernization has always emphasized the importance of technology transfer has gradually resulted in changes in the modes of production of almost all fishermen community. Changes in modes of production on fishermen community in the form of intermediate production tools, means of production and patterns of production relations of the traditional mode of production to a more modern mode of production on the one hand, has proven to make the work more effective and efficient fisherman and thus a wider range of sea allow fisherman to get a more satisfying catch. The other side changes in modes of production as a result of modernization fisherman fishing has also led to new problems on the fisherman, for example, only fisherman who have big capital are able to access modern means of production while the small fisherman remain in a disadvantageous position and increasingly marginalized because they can not access to modern means of production. This study was about nenelusuri how and to what extent the effect of changing modes of production to changes in the social structure of fisherman and changes in the pattern of relations of production and the potential for conflict in fishermen community. Results of this study revealed that the mode of production changes fisherman resulted in a change in the social structure of fisherman community. The use of modern fishing fleet requires huge capital and skilled labor and specialized skills in production, it makes the group fisherman who have big capital are at the top of the social structure, as well for fishermen who have the skill and expertise will occupy a special position in the social structure of fisherman community. The study also revealed that after the change in the mode of production Sape Bugis fisherman community, fisherman production relations turn into relations of production which tends to be exploitative of the small fisherman. The change modes of production also has led to various potentials conflict in fisherman community. The potential conflicts which arise in the case of fisherman community in sea area Bugis Sape can be described in two domains potential conflict is the First, potential conflicts between the fishing fleet is generally caused due to the use of fishing grounds overlap between modern fishing fleet with a fleet of traditional fishing tools and differences fishing and production methods among local fisherman with outsiders. Second, potential conflicts in the pattern of production relations. Potential conflicts can occur between the owners of capital with the owner or the owner's fishing fleet with fleet of fishing boat workers who tend to exhibit a pattern of exploitative relations of the fishermen and fisherman workers. Reality experienced by small fisherman strengthened the argument of Marx explained that with the development of the capitalist mode of production will very much be a gap between the people who control capital and means of production with the workers. To avoid the negative impacts of fisheries modernization and change the scrolling mode of production in almost all fishing communities, it must be accompanied by the following measures: First, attention to the condition of social stratification

Judul: Validation method for determination of apigenin in extract celery with high performance liquid chromatography
Abstrak: Apigenin is an active substance derived from celery (Apium graveolens) and widely used for the treatment of gout. Determination method of apigenin which have been validated was introduced by Frankee et al. J Food Compos Anal 17: 1-35 (2005). Apigenin analysis was done by high performance liquid chromatography (HPLC). To make sure that HPLC analysis method can be used for the intended purpose then the method was validated. Parameters determined on method validation were linearity, limit of detection, limit of quantification, precision, and accuracy. All parameters were in accordance with the acceptance criteria of Association of Official Analytical Chemist. The linearity in the concentration of 3,8; 5,7; and 7,6 mg/l had correlation coefficent of 0,9900–0,9998. limit of detection in this method was 2,7222 mg/l and limit of quantification was 8,2500 mg/l. Interday precision in five restating showed good precision with relative standard deviation of 3,85%. Accuracy was determined by standard addition method with recovery percentage of 95,00–118,77%. Average concentration of apigenin is 0,0052% (w/w).
