Judul: Peranan dan dampak pembangunan peternakan terhadap perekonomian wilayah pulau Timor Propinsi Nusa Tenggara Timur: pendekatan analisis input output
Abstrak: Nusa Tenggara Timur, khususnya Pulau Timor adalah salah satu daerah pensuplai ternak bagi wilayah lain di Indonesia. Oleh karena itu berbagai program telah dikem- bangkan di daerah ini untuk meningkatkan kemampuan produksi daerah, di samping untuk mempercepat pertumbuhan ekonomi, meningkatkan pendapatan dan konsumsi protein masyarakat. Pengetahuan tentang struktur ekonomi wilayah adalah informasi awal untuk mengetahui peranan dari sektor Ternak tersebut dalam perekonomian wilayah, dan bagaimana dampaknya terhadap percepatan pertumbuhan ekonomi, pen dapatan dan kesempatan kerja di dalam wilayah. Oleh sebab itu, tujuan dari penelitian ini adalah untuk mengetahui hal-hal tersebut di atas. Data dalam penelitian ini terdiri atas data primer dan data sekunder dari instansi pemerintah dan swasta sesuai sektor yang diteliti. Perekonomian wilayah dikelompokkan ke dalam 18 sektor ekonomi. Hasil penelitian menunjukkan bahwa struktur perekon nomian wilayah Pulau Timor tidak seimbang, di mana peran an sektor-sektor primer, terutama Tanaman Bahan Makanan, sangat besar. Sumbangan sektor Ternak terhadap PDRB mancapai 20,82% dan berada pada peringkat ke 2 setelah sektor Tanaman Bahan Makanan. Dari sumbangan sektor Ternak ini, 83,93% berasal dari Ternak Besar. Hak cipta iversity Output sektor Ternak sebagian besar (81,73%) dialo- kasikan kepada Permintaan akhir, yaitu rumah tangga, pembentukan modal dan ekspor. Nilai ekspor terbesar berasal dari Ternak Besar, yaitu 74,54% dari total ekspor wila yah ini. Tetapi, karena nilai impor yang cukup besar dan merata hampir pada semua sektor, menyebabkan neraca perdagangan wilayah tetap negatif. ...

Judul: Peranan Sektor Pertanian dalam Perekonomian Provinsi Nusa Tenggara Timur
Abstrak: Agricultural sector is still becoming the superior sector in the economy of Nusa Tenggara Timur (NTT) Province due to its significant contribution towards Gross Regional Domestic Product (PDRB) and labor absorption; however, this sector has not been the major source of economic growth. These study aimed are to analyze: (1) the role of the agricultural sector in the economy of NTT Province, (2) interrelation among agricultural sector with various other sectors in NTT Province, and (3) the impact on final demand changes in agricultural sector towards the output, income, and work force in NTT Province. This study used Input-Output (I-O) Method by conducting analysis on Input-Output Table of NTT Province in 2009. The result of the study show that: (1) sub-sector of animal husbandry and animal slaughtering, corn commodities, food-crop plant sub-sector, and fishery sub-sector play an immense role in the economy, (2) rice commodity, animal husbandry and animal slaughtering sub-sector, plantation sub-sector, and food crop plant sub-sector own a relatively enormous capability in supporting the output growth of their related sectors, and (3) poultry commodity and its products as well as coffee commodity posses output multiplier value, household income, and relatively large work force absorption. In order to increase the role of agricultural sector in the economy, agricultural sector growth is domestically oriented from the output side covering rice commodity, animal husbandry and animal slaughtering sub-sector, plantation plants sub-sector, as well as food crop plants sub-sector can be considered as development priority. Moreover, the government needs to carry out efforts to increase allocation for investment on animal husbandry and animal slaughtering sub-sector.

Judul: Mathematical model of Hematopoietic Stem Cell in Chronic Myelogenous Leukemia with and without Therapy
Abstrak: Leukemia or blood cancer is a diverse group of neoplastic disease, characterized by the multiplication of abnormal leukocytes or malignant transformation of blood-forming cells in bone marrow and lymphoid tissues. One of the most common types of leukemia is Chronic Myelogenous Leukemia (CML), which is usually diagnosed by the presence of certain chromosomal abnormalities, the so-called Philadelphia chromosome (Ph). One of the treatments of CML is Granulocyte Colony-Stimulating Factor (G-CSF). In this paper, we discuss two Hematopoietic Stem Cell (HSC) models, i.e. HSC without treatment and HSC with G-CSF treatment. The model of HSC without treatment included three equations representing the dynamics of HSC, leukocyte and platelet. Whereas, the model of HSC with G-CSF treatment includes the previous three equations and adds two more equations representing G-CSF injection and G-CSF circulation. The stability behavior of the system approaching the equilibrium points in the simulation study is carried out using Mathematica 7.0. The simulation results show that the G-CSF treatment can successfully decrease the number of HSC, which means reducing the CML.
