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: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
