Judul: Evaluasi Efektivitas Pembayaran Jasa Lingkungan Antara Kota Cirebon Dan Kabupaten Kuningan
Abstrak: Ecosystem conservation of watershed on the upstream area is a critical requirement in a continuous water management. This effort has to be supported not only by people that live at the upstream area as the „owner‟ of the catchment area but also by people at the downstream area as the „user‟. Therefore a comprehensive water management endeavor between the „owner‟ and the „user‟ is needed, through a payment of environmental services mechanism. This mechanism has been applied in West Java Province, specifically in Ciremai Mountain area – between Kuningan as the owner of the Paniis watershed and Cirebon as the user. Within the course of payment of environmental services, Kuningan and Cirebon keep identifying an accurate formula to manage the watershed area. Such circumstances place government in a consideration, whether the payment of environmental services program is effective in conserving Paniis watershed as the source of water of people in the city of Cirebon. It is critical to evaluate the effectiveness of payment of environmental services program in Paniis watershed, Ciremai Mountain to address the above question. Four main analyses have been employed to address that main question: (1) Cost and benefit analysis, (3) Willingness to pay analysis, and (4) Multinomial logit analysis. Results of the cost and benefit analysis of the payment of environmental services from 2003 - 2011 indicate that direct costs and direct benefits for Cirebon PDAM had been declining. These results conclude that the payment of environmental services of Cirebon PDAM is not effective to increase the production capacity of the institution. Results of willingness to pay analysis indicate that water users (costumers) have willingness to pay the environmental services of Rp.72/m 3. Based on the payment retrieval analysis: 49% of the respondents choose the payment through the monthly billing method, which is paid through the PDAM account.

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.
