Judul: Analisis dampak penetapan kawasan konservasi laut daerah kondisi sosial ekonomi nelayan (kasus daerah perlindungan laut kampung Saporkren, Distrik Waigeo Selatan, kabupaten Raja Ampat, Papua Barat)
Abstrak: Damage to coastal and marine resources in Indonesia leads to a conservation effort for ecosystem sustainability. Marine Protected Areas (MPAs) are established with the aim to protect marine ecosystems within and ensure the welfare of fishers living around the area. When MPAs are formed it will have an impact on limiting the rights of fishers and fishers fishing area changes, and also affect on the catch of fishers and their income. The goals of this research are to, (1) analyze the impact of MPA establishment against bundles of fishers’s rights, (2) analyze the impact of MPA establishment towards the income level of fishers. Results show that, (1) the establishment of MPA causes a change in the second type rights of fishers which is utilization type, while the access rights, management rights, and exclusion rights are retained by the fishers, (2) The establishment of marine protected areas give a positive effect on the income of fishers . Most of the fishers stated that the catch and their income increased since the establishment of MPA, caused by major increase of the fish quantity, which allowed fishers catches fish more easily.

Judul: Economic Benefit Analysis of Fishery Resource at Marine Protected Area of Karimunjawa National Park
Abstrak: Marine ecosytem has many benefits that provide an important economic justification for establishing Marine Protected Area (MPA), but these are often not fully understood by local community surrounding and stakeholders. This research was aimed to distinguish whether the establishment of Taman Nasional Karimunjawa (TNKj) as a MPA has contributed economic benefits of fishery resource to the local community as well as the regional economy. The change of benefit or loss rate was calculated using productivity approach of Economic Valuation Method and an iconic simulation. Location Quotient (LQ) analysis was applied to see the contribution of fishery sub sector to regional economic of Jepara. To know the perception of fishermen, Descriptive method was used. The Result showed that at present the economic benefit of fishery wasn’t quite significant, this probably corresponded to the increase of destructive fishing activities prior to the establishment of TNKj in 1999. The contribution of fishery sub-sector to Gross Domestic Product (GDP) of Jepara in 1999-2004 declined. However the datas indicated that the benefit would be obtained in afew years, as sea environment degradation declined and conservation management became more effective. As MPA, sustainable aspect is the most important thing, therefore the economic development should be in line with the ecology. It needs good management and coordination among all stakeholders as well as wider involvement of local community. The concept of collaborative management is proper to examine for advanced research.

Judul: Uji sifat listrik dan struktur kristal fotodioda ba0,5sr0,5tio3 dengan variasi pendadahan fe2O3
Abstrak: Ba0,5Sr0,5TiO3 (BST) thin film was doped by Ferium (Fe2O3) has been done with doping variation 2.5%, 5%, 7.5% and 10% above the substrate Si (100) p-type using chemical solution deposition (CSD) methods by spin coating technique at 3000 rpm for ± 30 seconds. Ba0,5Sr0,5TiO3 thin film made with 1 M concentration and the annealing temperature by 850oC. The results of current-voltage (I-V curves) characterization shows that the BST thin film and BFST are photodiodes. Electrical conductivity values BST and BFST thin films are in the range of semiconductor materials and obtain the electrical conductivity increased when the higher intensity light is used. The result of the dielectric constant increases with the addition of Fe2O3 doping. SEM results showed that the BST and BFST material is a thin film with thickness of the order 10-6 m. Result of XRD showed that BST and BFST is cubic.
