Judul: Dampak Pembangunan Bandara Internasional Lombok terhadap Perekonomian Provinsi Nusa Tenggara Barat
Abstrak: Nusa Tenggara Barat (NTB) is one of the provinces that indicate an improvement in its economy. In the last three years the NTB’s Gross Regional Domestic Products (GRDP) indicates improvement annually. The construction of Lombok International Airport (LIA) is one of the efforts to boost NTB’s economy. It was done so that this new airport that was built in Tanak Awu, Central Lombok could accommodate more passengers or visitors who come directly to NTB. This paper analyzes the contribution of LIA to the NTB’s economy. The analytical method used is Input-Output Analysis which is applied in the NTB 2005 Input-Output Table with the 25 sector classification and in which aggregated to the 13 sector classification. LIA is included in the building sector classification approach. This classification causes the results of this paper are not thorough since the impacts caused are actually greater than those caused only by the building sector. In its progress, after LIA was operated, it can evoke other economic sectors besides building. The analysis done includes the linkage analysis, dispersion impact analysis, and multiplier analysis. From the results of the analysis, it can be concluded that the building sector (airport) has greater backward linkage compared to the forward linkage. This indicates that buildings sector (airport) has ability to attract strong growth in the upstream sector. The impact of external shock investment of LIA indicate that the investment potential for increasing output and household incomes province of NTB. To increase the role of the building sector (airport), government should be trying to push production capacity because it is still lacking in providing input for other sectors. Hence the government must be able to overcome various constraint to attract investor to invest in building sector (airport).

Judul: Peranan Investasi Pembangunan Infrastruktur Transportasi Dalam Perekonomian Daerah (Studi Kasus : Bandara Internasional Sepinggan-Kalimantan Timur)
Abstrak: Pembangunan ekonomi di Indonesia saat ini diarahkan untuk peningkatan pertumbuhan ekonomi, penciptaan tenaga kerja dan pengurangan kemiskinan. Pemerintah yang berperan sebagai perencana dan pelaksana pembangunan ekonomi menetapkan program jangka panjang yaitu program Masterplan Percepatan Perluasan dan Pembangunan Ekonomi Indonesia (MP3EI). Dalam program ini terdapat tiga kerangka desain strategi utama yaitu pengembangan potensi melalui enam koridor utama ekonomi, pengembangan konektivitas nasional dan peningkatan kapasitas SDM dan IPTEK dalam koridor. Infrastruktur yang dalam hal ini merupakan faktor penunjang menjadi perhatian utama baik bagi pemerintah pusat maupun pemerintah daerah lokasi penetapan koridor ekonomi. Kalimantan Timur sebagai salah satu lokasi penetapan koridor pertumbuhan ekonomi menempatkan pembangunan infrastruktur pada urutan utama pembangunan daerah saat ini. Salah satu infrastruktur yang dikembangkan adalah pembangunan Bandara International Sepinggan. Pembangunan ini diharapkan dapat menunjang kegiatan-kegiatan ekonomi yang terkait dengan keberadaan bandara tersebut serta terjadi peningkatan output, pendapatan masyarakat serta peningkatan PDRB. Penelitian ini bertujuan menganalisis sejauh mana peran pembangunan infrastruktur khususnya bandara dalam perekonomian Provinsi Kalimantan Timur. Metode yang digunakan adalah analisis Input-Output dengan menggunakan program IOAP (Input Output Analysis for Practitioners) dan Microsoft Excel. Data yang digunakan adalah data sekunder yang berasal dari Tabel Input-Output Provinsi Kalimantan Timur Tahun 2009, klasifikasi 50 sektor. Analisis yang dilakukan terdiri dari analisis keterkaitan, analisis dampak penyebaran, dan analisis pengganda (multiplier) serta simulasi investasi pembangunan untuk perluasan Bandara Internasional Sepinggan dari APBD Bappeda Provinsi Kalimantan Timur dan PT. Angkasa Pura I. Dari analisis yang dilakukan dapat diketahui bahwa sektor bangunan yang mewakili keberadaan bandara dalam Tabel IO Provinsi Kalimantan Timur tahun 2009 memiliki kemampuan untuk meningkatkan permintaan output dari sektor lain yang akan dijadikan input dalam kegiatan ekonominya yang berarti bahwa sektor bangunan lebih mendorong pertumbuhan sektor hulunya. Berdasarkan simulasi investasi yang dilakukan, pembangunan Bandara Internasional Sepinggan dapat meningkatkan output dan pendapatan rumah tangga masyarakat. Dengan mempertimbangkan kontribusinya terhadap peningkatan output dan pendapatan masyarakat maka pembangunan infrastruktur sudah sepatutnya menjadi perhatian dan prioritas utama bagi pemerintah pusat dan daerah dalam rencana pembangunan untuk menunjang kegiatan ekonomi dalam upaya peningkatan perekonomian

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.
