Judul: Strategi Pengelolaan Sumberdaya Perikanan Karang untuk Pemanfaatan yang Berkelanjutan (Kasus: Kepulauan Ayau, Kabupaten Raja Ampat, Provinsi Irian Jaya Barat)
Abstrak: Indonesia failure to get property rights to Sipadan and Ligitan Island represent worth experience about importance of development policy to increase the social welfare in boundries island. Potency consideration and regional specific characteristics is properly placed forward in stimulating of development policy. Ayau Archipelago is one of boundry island in Raja Ampat Regency owning big enough reef fishery potency. Research objective were designed as the strategy of reef fishery resources management for sustainability exploitation in Ayau archipelago, Raja Ampat Regency. SWOT analysis is used to evaluate sustainability of management activities. The sustainability index shows 0,98 which mean reef fishery management activities was unsustain. There were some strategies to anticipate the condition; (1) friendly reef fishery management, (2) optimalization of reef fish potency, (3) development of business system, (4) development of PIR system in business ,(5) development of institution, (6) infrastructure repair of commerce and communication, (7) modernization and motorization of fishing unit, and (8) resource management base on society.

Judul: Pengelolaan Sumberdaya Terumbu Karang Dalam Kawasan Pengembangan Wisata Bahari KKLD Selat Dampier Kabupaten Raja Ampat.
Abstrak: The area of Gam island, Mansuar and Kri of island in the north MPAs of Dampier Strait Raja Ampat regency has potential of coral reef resources for development of marine tourism. The focus management of coral reef to economic rise with management non extractive. The objectives of this research was (a) to analyze the suitability and carrying capacity of coral reef ecosystem for tourism development and (b) to analyze partsipation of stakeholder in management of coral reef resources. The coral reef ecosystem can be used to study its suitability for marine tourism objects of diving. Collected data were life form of coral reef, coral fish, current speed, water transparency and coral reef depth. The formula used to determine tourism suitability is suitability matrix of diving, and Scenic Beauty Estimation (SBE) to judge the quality of landscape. Line intercept transect method showed that islands of Gam, Mansuar and Kri area had a condition of coral reef in the category of “good” with the average coral coverage is 63.75%. However, public participation in the management of coral reefs for the development of marine tourism to has not been done its full potential according to the analysis of community participation.

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.
