Judul: Analisis kapasitas berlebih perikanan Pukat  Cincin Pekalongan dalam kerangka kebijakan perikanan tangkap di Laut Jawa dan sekitarnya
Abstrak: Excess capacity and overfishing have been identified as the two most important problems presently facing small pelagic fisheries in Java Sea. Here a bioeconomic model was applied as an approach for depicting the current status of Pekalongan fisheries and capacity utilization rate, as well as Data Envelopment Analysis (DEA) for estimating efficiency of purse-seiner, assessing economic impact of resources and setting an alteration policy in capture fisheries.

Abstrak: Pemanfaatan sumberdaya ikan telah memberikan manfaat secara ekonomi kepada pelaku usaha akan tetapi pemanfaatan sumberdaya ikan ini juga memberikan dampak eksternalitas. Sumberdaya ikan bersifat renewable resources (sumberdaya yang dapat pulih) tetapi bukan berarti tak terbatas sehingga apabila tidak dikelola secara hati-hati, akan memberikan dampak negatif terhadap ketersediaan sumberdaya ikan dan lingkungan. salah satu permasalahan dalam perikanan tangkap adalah terjadinya kelebihan kapasitas tangkap (overcapacity) yang mendorong terjadinya kelebihan tangkap (overfishing)., Extraction of fishery resources has benefited both fishing industries and society. However, there is externalities associated with such an extraction. Fish is renewable resource, neverthelless, exploitation of the resource above and beyond its maximum capacity will have negative impacts biologically, economically and socially. Evercapacity seems to be the major problems faced by fishing industry nowadays.

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.
