Judul: The role of infrastructure as an accelerator the dynamic of agricultural base sectoral and regional economy
Abstrak: Infrastructure is the foundation for all economic activity and industry. The infrastructure provision in Indonesia faci ng on the limited of public financial and low of private investment problems. The financiang and funding availability for development of infrastructure in various islands and regions are the biggest obstacle. As the consuquently of these fundings limitations, the strategy for prioritying the limited fiscal available could be focosed for a spesific sector and regions which have strategic importance for expanding wide economic activities. The objectives of this research is to analize the infrastructure role as an accelerator of agricultural base sectoral and regional economy. Method of analysis is carried out by combining estimated production function which develop outside traditional CGE. The top-down Regional Computable General Equilibrium economic model (CGE) was employed. The estimation of production function shows that rice production and aggregate agricultural sector are more responsive to irrigation infrastructure. While othe r sectors are more responsive on road infrastructure.

Judul: Dampak Pembangunan Infrastruktur dan Aglomerasi Industri terhadap Pertumbuhan Ekonomi Regional di Indonesia
Abstrak: In general, the Indonesia’s economic growth is significantly improved recently but the increase rate is different in each region which entitles to high regional disparity. One of the reasons why it occurs is because of the difference of infrastructure development in every region. Beside, the centralization of the economic activities tends to cause this issue. This study intends to analyze the effect of infrastructure development and industrial agglomeration to the regional economic growth in Indonesia. Based on productivity function of Cobb-Douglas model, the fixed effect model is used as data panel method which includes a range of data from 26 provinces in 1991-2007. The estimation in this study ensues to the influence of labor, investment, human capital, physical infrastructures (electricity and roads), industrial agglomeration, and economic crisis in 1997, while water infrastructure is not significant. Due to the estimation data result, the characteristic of production activity in Indonesia is labor-based with the labor elasticity rate of 0,27 higher than investment elasticity which is 0,10. Human capital variable holds the biggest effect with 0,34 score. Physical infrastructure (electricity and roads) is significantly influential with electricity elasticity indicates 0,33 score, higher than roads elasticity score of 0,13. In addition to this, industrial agglomeration contributes positive effect on economic growth which is indicated by 0,04 elasticity score. On the other hand, the negative coefficient score as a result of economic crisis in 1997 obstructs the economic growth. To sum up, variables which deliver positive influence for regional economic growth in Indonesia are human capital, electricity, roads, and industrial agglomeration. Furthermore, distribution of infrastructure development, education, and centralization of the economy activity should be applied in order to reduce regional disparity.

Judul: Penentuan jenis kelamin merpati kipas (columba livia) berdasarkan kromosom, hormon, ornamen bulu, tingkah laku seksual dan nilai hematologis
Abstrak: Pada penelitian ini diujicobakan penentunan jenis kelamin berdasarkan analisis kromosom, penentuan kadar hormon estrogen, pengukuran panjang barbula bulu, pengamatan tingkah laku seksual dan penentuan nilai hematologis terhadap 20 ekor burung merpati kipas, yang terdiri dari 10 ekor dewasa dan 10 ekor lepas sapih. Dengan kombinasi 0.5 ml darah utuh, 300 μl phythohemaglutinin, 1 ml fetal calf serum dan 5 ml media kultur RPMI 1640, diperoleh lebih dari 10 kumpulan me tafase kromosom dalam satu preparat. Analisis kromosom dengan teknik kultur darah hanya 0.5 ml ternyata dapat membedakan jenis kelamin merpati kipas dewasa maupun lepas sapih. Jumlah kromsom diperoleh 40 pasang dan tipe pasangan kromosom seksnya adalah metasentrik. Hasil penentuan kadar hormon estrogen serum darah menunjukkan bahwa pada merpati kipas betina dewasa kadar estradiol serumn ya 6.529 ± 2.575 p g/ml lebih tinggi (P<0.01) dari pada yang jantan dewasa, 2.011 ± 0.400 pg/ml. Sedangkan untuk merpati kipas betina lepas sapih, 3.007 ± 1.201 pg/ml, tidak berbeda nyata (P>0.01) dengan merpati lepas sapih jantan 1.678 ± 0.190 pg/ml. Pengukuran panjang barbula bulu merpati kipas dewasa jantan didapatkan panjang barbula sayap 346.18 ± 5.15 μm, ekor 388.9 3 ± 39.82 μm, dan badan 371.45 ± 28.80 μm lebih panjang (P<0.01) dari pada panjang barbula bulu sayap, ekor, dan badan burung merpati kipas betina, masing-masing adalah 303.81 ± 6.94 μm, 292.03 ± 26.50 μm, 285.76 ± 40.09 μm, tetapi untuk panjang barbula bulu sayap, ekor dan badan pada burung merpati kipas lepas sapih tidak berbeda (P>0.01) antara jantan dan betina. ...
