Judul: Kontribusi Sektor Kehutanan Terhadap Ekonomi Kabupaten Tasikmalaya
Abstrak: Conventionally the role of forestry sector can be proxied by the contribution of that sector to the Gross Domestic Product (GDP). 17% of the Tasikmalaya district areas are forest land. The result showed the contribution of forestry sector to regional gross domestic product ranged from 4.39% to 4.98%. The forestry sector is a basic sector as indicated by LQ value of 2.80 to 3.05 and has a multiplier effect value of 13.315 in 2012. The SWOT analysis showed the forestry sector should use its strengths to capture opportunities. In order of importance, policy that are needed : Collaborative and Community Forest Management (CBFM and CM), Ecotourism development (PE), Rehabilitation of critical lands, and Strengthening forest products industry.

Judul: Kontribusi Sub Sektor Kehutanan terhadap Ekonomi Kabupaten Sumedang
Abstrak: Products of forestry sub-sector can be extractive and nonextractive. Sumedang district with a land area of 152,220 hectares is dominated by the agricultural sector amounted to 83.73%, including state forest lands and community forest by 36.24%. The extent of forest land allocation is an advantage for the forestry sub sector in Sumedang district. The results of the contribution analysis indicate that the forestry sub sector contributing 0.53 % - 0.73 % of GDP Sumedang district. Although a small contribution, but the forestry sub sector is a basic sector with value of LQ 3.42 - 5.76. Multiplier effect value of forestry sub sector in 2012 amounted to 45.67. This means that any additional income of Rp. Y in the forestry sub sector, resulting in additional revenue of 45.67 x Rp. Y to the total regional GDP of Sumedang district.

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.
