Judul: Analisis Struktur Produksi, Konsumsi dan Perdagangan Beras di Propinsi Nusa Tenggara Timur
Abstrak: Salah satu wilayah di luar Jawa yang secara agroklimat kurang mendukung pengembangan padi dalam skala besar adalah Propinsi Nusa Tenggara Timur (NTT). Laju pertumbuhan produksi baik melalui pertambahan luas tanam/panen maupun peningkatan produktivitas padi, belum mampu mengimbangi laju pertumbuhan permintaan beras yang terus meningkat dari tahun ke tahun. Pertanyaan yang kemudian muncul adalah: faktor-faktor apakah yang mempengaruhi struktur produksi, konsumsi maupun perdagangan beras di propinsi Nusa Tenggara Timur ?. Selanjutnya pertanyaan ini dikembangkan untuk melihat kebijakan apakah yang dapat ditempuh guna menjamin ketersediaan pangan beras bagi masyarakat NTT, dengan mempertimbangkan kesejahteraan producen dan konsumen ? Tujuan dari penelitian adalah untuk : (1) mendeskripsikan pusat-pusat pertumbuhan produksi padi di NTT berdasarkan kondisi geografis, sosial ekonomi, penggunaan lahan, sistem produksi, pola konsumsi dan perdagangan beras, (2) menganalisis faktor-faktor yang mempengaruhi struktur produksi, konsumsi, dan perdagangan beras di propinsi NTT, dan (3) menganalisis mensimulasi dampak alternatif kebijakan pemerintah terhadap produksi, konsumsi, dan perdagangan beras, serta kesejahteraan produsen dan konsumen...dst

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.
