Judul: Benefits of Segara Anakan mangrove conservation for shrimp fishery in inshore water of Cilacap region
Abstrak: Segara Anakan is unique ecosystem that are closely interrelated with open water areas, marshes and mangrove ecosystem, it is habitat for various species of flora and fauna. it has important ecological, economic and social functions. Ecologically, this area is a sawning and nursery ground for marine lifes that can effluence to the catch of fisherman in South Java, due to declining mangrove area, the value of economic activity in this area is also decreasing.

Abstrak: Cilacap is one of fishery centers in Indonesia, with one of the common best product is shrimp. Shrimp capture fisheries in Cilacap are majority using trammel net. Nowadays, the actual condition shows that it occured biological degradation on shrimp resources. This marked by production decline on shrimp production. Shrimp production on among 2004-2008 declined on average 7,2%. To achieve the study goals, the data was analyzed by 4 approaches: 1) Specifying maximum sustainable yields of shrimp resources in Cilacap by bioeconomy analysis; 2) Mapping mangrove area in Cilacap by using Geographic Information System Analysis; 3) Reviewing the factors of shrimp production decline by Ishikawa method; 4) Arranging management model by SWOT analysis and Analytic Hierarchy Process (AHP). SWOT analysis used for arranges the management strategy of shrimp resources. While Analytic Hierarchy Process (AHP) used for support arrangement of some priority from many choices. This study proved that shrimp production decline is in the line with mangrove area decline. Mangrove area decline influenced toward shrimp population and in the future will cause shrimp production decline. Considering the significant of mangrove advantages for fish resource sustainability, so strategy for increasing environmental capacity and shrimp resources, as the result on AHP analysis have to be implemented intensively. It is expected by the recovery or better environment capacity, that is mangrove then shrimp population will increase and makes chance to increase shrimp production by fishers. The most fifth actors that have crucial role on the declination of shrimp landings are government, community, stake holders, non-organizational government, and academics who must be simultaneously work together to run the strategy so can improve the weakness and threat, and also creates achievement on shrimp resources sustainability and the most is shrimp fishery business will be continued and gives benefit to all of parties who involved on shrimp fishery.

Judul: Sintesis BaTiO3 dari Campuran Ba(OH)2 dan TiO2 dengan Tambahan PbO
Abstrak: Piezoelectric material can generate electric field in response to applied mechanical stress. Conversely, they can stretch and contract in response to an electric field. This material can be used for many applications such as transducer, microphone, ultrasound, and pressure gauge. Barium titanate is a ferroelectric material with piezoelectric properties that can be synthesized easily. The aim of this study is to synthesis barium titanate from mixture of Ba(OH)2 and TiO2, also observe its optimum temperature and the effect of PbO addition. The method of synthesis was solid-state reaction and sol-gel method, then the products were characterized with x-ray diffraction (XRD). Based on XRD analysis, the optimum temperature for both methods was 800°C. Addition of PbO to BaTiO3 in the solid-state reaction formed a compound with formula of Ba1-xPbxTiO3. The addition has changed diffraction pattern peak at 2θ and strengthened its tetragonal structure. The best result was obtained at x of 0.5 which will form a compound of Ba0.5Pb0.5TiO3.
