Judul: Analisis kesediaan membayar (willingness to pay) secara pra-upaya terhadap peningkatan kualitas pelayanan kesehatan masyarakat di kabupaten Lombok Barat
Abstrak: Sistem pembayaran pra-upaya merupakan suatu upaya untuk meningkatkan efisiensi pembiayaan kesehatan dalam rangka peningkatan kualitas dan pemerataan pelayanan kesehatan. Di Indonesia, sistem pembayaran ini dikembangkan dalam bentuk kelembagaan JPKM (Jaminan Pemeliharaan Kesehatan Masyarakat). Penelitian ini bertujuan mengkaji pilihan dan kesediaan membayar (willingness to pay/WTP) masyarakat Kabupaten Lombok Barat terhadap sistem pembayaran ini serta kelembagaannya.

Judul: Kajian Mekanisme Pembayaran Jasa Lingkungan Penyediaan Sumberdaya Air (Studi Kasus di Kabupaten Lombok Barat dan Kota Mataram, Nusa Tenggara Barat)
Abstrak: The springs at the upper Jangkok watersheds are the supplier of clean water for West Lombok District, Mataram City and some areas in Central Lombok District society. Sesaot forest area are the headwaters of Jangkok watershed. Most of their area has been managed by farm-forest society with Community Forest Management system (CFM). There are many problems in Jangkok watershed area, such as land degradation, many potential damage of biophysical aspects and institutional aspects of forest community groups, a decreasing of springs number and the lowering of average water debit at Jangkok river, landsliding, erosion, sedimentation and water crisis threathening as the result of water debit decreases and water demand increases. The upstream society as a service providers had been required to protect the land cover and the same time they are has had their lives on. Downstream society in Mataram City utilizing the environment services of water through PDAM. The downstream society moval for water preciousness, which should be used as economic goods, and payments for the upstream society who preserves watersheds in the catchment area, known as the payment for environmental services (PES) mechanism. An efforts in West Lombok District, supported by local regulation West Lombok District No. 4/2007 about management of environmental services for water utilization and tourism, is a form of payment for environmental services mechanisms. Payment for environmental services mechanisms was a new scheme in Indonesia. For further application, learning is needed for the involved parties, each stakeholder role, law enforcement, regulations and agreements along with the stakeholder succesfullness at the field. This performances included the field realities and each party benefits. The data had been collected by triangulation method : interview, field observation and documents tracking. Stakeholder analysis method and qualitative descriptive analysis had been used for data analysis. Stakeholder which are involved in PES mechanism for water resources supply in West Lombok District and Mataram City identified as many as 18 stakeholder. PES mechanisms for water resources supply in West Lombok District and Mataram City managed by IMP and it has a legal basis. It is counted as pure PES. Its fulfill five criteria there are voluntary transaction, well-defined environmental service, a buyer and provider of environmental services, and environmental services provider secures environmental service provision.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
