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: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
