Judul: Analisis Konsentrasi Spasial dan Faktor yang Memengaruhi Aglomerasi Industri Manufaktur di Kawasan Barat Indonesia
Abstrak: Regional inequalities can be occured because of differences in resources and the economic activity generated by each region. Manufacturing industry is important sector that can encourage growth and development of other sectors. The purposes of this research is to analyze the development of regional imbalances, spatial concentration and agglomeration factor of manufacturing industry in the western region of Indonesia. This research uses the analysis tool Williamson Index, Geography Information System (GIS), Hoover Balassa Index and panel data. Results of the study indicate that there is a relatively medium regional imbalances in the distribution income and there are regions have point of consentration spatial of manufacturing industries. Variables that constantly affect the agglomeration of manufacturing industry is Competition Industry Index, size of company, foreign investment, road, value added and number of large and medium manufacturing industries. Map of the distribution of the location of the manufacturing industry which is more evenly distributed can increase the income and welfare of society.

Judul: Dampak Aglomerasi Industri terhadap Disparitas Regional di Indonesia tahun 2008-2015.
Abstrak: Sektor industri memiliki kontribusi besar terhadap pertumbuhan ekonomi dan lapangan kerja, tetapi distribusi sektor industri yang tidak merata antara Jawa dan luar Jawa menyebabkan aglomerasi industri hanya terjadi di daerah tertentu. Studi ini menggunakan indeks Hoover’s coefficient of localisation (HL) dan indeks Krugman’s specialisation (KS) untuk menjelaskan aglomerasi industri dan menggunakan indeks Coefficient of variation (CV) dan indeks Locational gini coefficient (LG) untuk menjelaskan disparitas regional. Untuk menganalisis dampak aglomerasi industri terhadap disparitas regional di Indonesia digunakan analisis data panel statis fixed effect model. Untuk mengetahui dampak aglomerasi industri terhadap disparitas regional di Indonesia secara spasial digunakan analisis Geograpichally Weigthted Panel Regression (GWPR). Data yang digunakan adalah data panel dari 33 provinsi di Indonesia dari 2008 hingga 2015. Aglomerasi industri dan disparitas regional terjadi di Indonesia. Di tahun 2008 sebanyak 21 provinsi di Indonesia atau sebesar 64.65% mengalami aglomerasi dan di tahun 2015 jumlahnya menurun menjadi 15 provinsi atau sebesar 45.45%. Penurunan ini terjadi karena adanya perpindahan industri ke lokasi industri yang baru dan pertambahan jumlah pusat industri di lokasi yang baru. Industri di Indonesia terkonsentrasi di Pulau Jawa. Hasil uji data panel menunjukkan disparitas regional terjadi untuk semua kelompok industri di Indonesia dilihat dari tenaga kerja dan nilai tambah. Hasil uji juga memberikan hasil bahwa lokalisasi industri dan factor intensity meningkatkan disparitas regional, sedangkan pengaruh spesialisasi industri, scale economies, dan resources intensity terhadap disparitas regional belum dapat disimpulkan. Hasil uji data secara spasial menunjukkan bahwa aglomerasi mampu menurunkan disparitas regional. Hasil uji juga memberikan hasil bahwa lokalisasi industri, spesialisasi industri, scale economies, resource intensity, dan factor intensity meski menunjukkan hasil yang berbeda untuk setiap kelompok industri.

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.
