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: Model of Infrastructure Development at the Tertiary Level of Irrigated Paddy Field
Abstrak: Food production will decline by increasing the conversion of agricultural land. Important factor that also affect food production in Indonesia is generally Indonesian farmers are conventional farmers who live below the poverty line. One of solution to overcome the low production of food and farmer's low income is the development of farm infrastructures on agricultural land. The purpose of study were (1) to identify the infrastructures needed at the tertiary level of irrigated paddy field, (2) to build a dynamic model of infrastructure development at the tertiary level of irrigated paddy field and (3) to make recommendations on development of infrastructure at the tertiary level of irrigated paddy field. Steps of the systematic approach to build the farm infrastructure model at the tertiary level in irrigated paddy field were analysis of needs, problem formulation, system identification, system modeling (STELLA), model validation, sensitivity analysis and model simulation. Farmers need a more adequate farm infrastructure, such as pipe irrigation and farm roads for on-farm infrastructures and rice processing complex and groat processing machine for off-farm infrastructure. Model of infrastructure development at the tertiary level of irrigated paddy field represented the real system and it was used to design the infrastructure development at the tertiary level of irrigated paddy field. Infrastructures development should be done in integrated farming system with minimum total area of 3000 hectares. It provided the benefits for the farmers if every farmer had a minimum of 3 hectares of land area.

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. ...
