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.

Judul: Model Pengelolaan Sumberdaya Udang Penaeidae spp di Kabupaten Cilacap Provinsi Jawa Tengah
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 Timbal Zirkonat Titanat (Pb(ZrxTi(1-x))O3) dengan Metode Lelehan Garam: Pengaruh Suhu dan Waktu Sintering
Abstrak: Timbal zirkonat titanat (Pb(ZrxTi(1-x))O3, x = 0.52) atau PZT merupakan suatu bahan keramik perovskit yang memiliki sifat piezoelektrik sangat baik dibandingkan bahan lainnya. Ukuran bahan ini sangat penting untuk aplikasi ultrasonografi, sehingga diperlukan metode sintesis yang dapat mengendalikan ukuran PZT, salah satunya adalah metode lelehan garam. Metode ini dapat mengendalikan ukuran partikel dengan meragamkan parameter sintesis, seperti suhu dan waktu sintering. Pembentukan PZT diawali dengan reaksi PbO dan TiO2 membentuk intermediet PbTiO3 lalu bereaksi dengan ZrO2 membentuk PZT. Produk sintesis dicirikan dengan difraktometer sinar-X, mikroskop elektron payaran, penganalisis ukuran partikel, dan adsorpsi Brunauer Emmett Teller. PZT dengan metode lelehan garam berhasil disintesis pada suhu sintering 775 °C selama 4 jam. Suhu dan waktu sintering tidak secara nyata memengaruhi ukuran partikel dan kristalinitas PZT. Partikel terkecil 659 nm diperoleh pada suhu sintering 875 °C selama 4 jam.
