Judul: Analisis dampak pemekaran wilayah terhadap perekonomian wilayah kepulauan dan pengembangan pariwisata Bahari (Studi kasus di Kabupaten Raja Ampat Provinsi Papua Barat)
Abstrak: Kabupaten Raja Ampat merupakan kabupaten baru hasil pemekaran dari Kabupaten Sorong berdasarkan Undang-Undang Republik Indonesia Nomor 26 Tahun 2002 tentang Pembentukan 14 Kabupaten Otonom Baru di Tanah Papua, dengan luas wilayah 4,6 juta hektar (46.296 km2) yang terdiri dari 10 distrik dengan jumlah penduduk 32.175 jiwa (2006). Penelitian ini mempunyai tujuan untuk: (1) mengidentifikasikan faktor-faktor yang menjadi dasar pertimbangan dalam proses perumusan kebijakan pemekaran wilayah Kabupaten Raja Ampat , (2) mengetahui dampak pemekaran wilayah terhadap perkembangan perekonomian wilayah kepulauan Kabupaten Raja Ampat dan Kabupaten Sorong, (3) mengetahui dampak pemekaran wilayah terhadap kapasitas fiskal pemerintah daerah Raja Ampat dan Sorong (4) mengetahui sektor usaha yang menjadi unggulan dan prioritas pengembangan dalam struktur perekonomian wilayah Kepulauan Raja Ampat setelah pemekaran, (5) mengetahui kontribusi sektor pariwisata bahari terhadap ekonomi wilayah kepulauan dan strategi pengembangannya di Kabupaten Raja Ampat, (6) mengetahui dampak pemekaran wilayah terhadap kesejahteraan masyarakat di Kabupaten Raja Ampat.

Judul: Rencana Pengembangan Kawasan Ekowisata Pesisir Interpretatif di Kawasan Konservasi Laut Daerah Selat Dampier Kabupaten Raja Ampat Provinsi Papua Barat
Abstrak: This paper describes the establishment of ecotourism area planning using spatial approach in Selat Dampier Conservation Area of Raja Ampat West Papua Province. This area include in development nodal integrated tourism, sea protectorate area and multipurpose protected area. This research was carried out using both quantitative descriptive and quantitative spatial methods to assess land suitability for tourism activities; avaiability object and attraction; and acceptability and opportunity empowerment local community (indepth interview). Variables using GIS integration of those, producted utilization of coastal ecotourism zone and interpretative tracking. The research results show that Friwen and Arborek Islands are suitable for development of coastal recreation and snorkeling. However, mangrove ecotourism can be performed only in Arborek Island. Local community as well highly supports the ecotourism area development and activities that may increase the economic income. Based on potency of ecological suitability, community acceptability and opportunity empowerment of local community, intensive and semi intensive zone are provided. Arborek Island has intensive zone area wider than Friwen Island. Intensive zone of those two island can be developed as interpretation tracking which may educated tourists.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
