Judul: Analisis Spasial untuk Perumusan Kebijakan  Pengembangan Kawasan Pulau-Pulau Kecil (Studi Kasus  Gugus Pulau Kaledupa Kabupaten Wakatobi)
Abstrak: Indonesia adalah Negara kepulauan terbesar di dunia dengan 17.504 buah pulau yang lebih dari 10.000 pulau diantaranya adalah pulau-pulau berukuran kecil dan sangat kecil. Kawasan pulau–pulau kecil ini memiliki potensi ekonomi penting, namun kesejahteraan masyarakat pada kawasan tersebut relatif rendah sehingga sebagian besar penduduk di kawasan pulau-pulau kecil dan pesisir masih hidup di bawah garis kemiskinan. Kebijakan pengembangan kawasan pulau kecil harus lebih spesifik dan terpadu baik antar sektor pembangunan dan antar wilayah. Analisis spasial adalah salah satu model perumusan kebijakan pembangunan yang berbasis ilmu pengetahuan untuk memperhitungkan berbagai keterkaitan potensi ekonomi baik intra maupun antar wilayah sehingga dapat dimanfaatkan secara optimal untuk mendorong kinerja pembangunan. Penelitian ini merupakan studi kasus di kawasan Gugus Pulau Kaledupa Kabupaten Wakatobi dengan tujuan untuk menganalisis: (1) pola asosiasi potensi ekonomi kawasan Gugus Pulau Kaledupa, (2) pola spasial tipologi potensi ekonomi kawasan Gugus Pulau Kaledupa, (3) model hubungan fungsional antara potensi ekonomi dengan kinerja pembangunan, dan (4) merumuskan rekomendasi kebijakan pengembangan kawasan Gugus Pulau Kaledupa. Untuk menjawab tujuan penelitian ini digunakan alat analisis kuantitatif yakni: Principal Components Analysis (PCA), Tree Clustering, K-Means Clustering, dan Spatial Durbin Model. Data penelitian berasal dari berbagai sumber seperti; BPS, COREMAP dan Forkani. Unit wilayah analisis terkecil penelitian ini adalah desa dengan jumlah 26 desa. Desa Lagijaya dibagi atas 2 wilayah unit analisis yaitu wilayah daratan dan Pulau Hoga. Variabel dianalisis sebanyak 111 variabel indikator.

Judul: Management design of small islands based on space utilization (case Kaledupa Islands, Wakatobi Regency)
Abstrak: This research was conducted in Kaledupa islands (GPK), Wakatobi regency Southest Sulawesi. The research objective is to arrange the pattern of space utilization in the small islands based on eco-space value. The value of eco-economic space obtained by comparison 36:64’s protected and sea farming areas of totally area of GPK. Result of analysis showed that the pattern of composition GPK space directed to the tourism and fisheries sectors, consist of 7 723.22 Ha (36.31% GPK) of protected areas and 13 549.65 Ha (63.69% GPK) of cultivation areas.

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.
