Judul: Evaluation of Situ Gede Tourism Landscape  Management, Tasikmalaya City
Abstrak: Tasikmalaya memiliki posisi strategis untuk area pariwisata. Salah satu destinasi wisata alam di Kota Tasikmalaya adalah area pariwisata Situ Gede. Selain sebagai tempat wisata, Situ Gede memiliki fungsi penting lainnya seperti reservoir air, sumber daya perikanan serta sumber daya air. Namun, Situ Gede Tasikmalaya mengalami penurunan kualitas serta fungsi, sehingga memerlukan evaluasi pengelolaan. Tujuan penelitian ini yaitu menilai kualitas lingkungan Situ, menilai kelayakan objek dan daya tarik wisata Situ Gede, mengevaluasi pengelolaan lanskap wisata Situ Gede serta menyusun rekomendasi pengelolaan sebagai upaya pengembangan dan pelestarian lanskap wisata Situ Gede. Metode penelitian ini terdiri dari: (1) analisis kondisi lingkungan situ; (2) analisis kelayakan objek dan daya tarik wisata; (3) analisis preferensi dan persepsi terhadap objek wisata dan pengelolaan lanskap wisata (4) analisis kesenjangan. Hasil penelitian menunjukkan bahwa kualitas lingkungan Situ Gede dalam kondisi terganggu. Kesesuaian dan kelayakan objek dan daya tarik wisata Situ Gede termasuk dalam kategori sedang. Selain itu, berbagai kegiatan pengelolaan lanskap wisata Situ Gede telah dilaksanakan oleh pengelola, namun beberapa aspek perlu ditingkatkan seperti fasilitas dan pemeliharaan. Rekomendasi pengelolaan berfokus pada empat program yaitu perbaikan dan penambahan fasilitas, revitalisasi situ, peningkatan partisipasi pengelolaan lanskap wisata serta pengadaan program atau aktivitas wisata., Tasikmalaya is a strategically positioned city for tourism. Among its natural tourist destinations, Situ Gede stands out. As a tourist spot, it also fulfills important environmental functions such as water reservoir, fisheries resources, and water resources. Lately, Situ Gede has been facing quality and function decreases, thus requiring management evaluation. This research aims to assess the environmental quality of the site, assess the suitability and feasibility of tourism objects and attractions, evaluate the tourism landscape management, and compose managerial recommendations for the development of the site. The methods include an analysis of the environmental conditions, a suitability and feasibility assessment of tourism objects and attractions, an assessment of preferences and perceptions toward tourism objects and tourism landscape management, and a gap analysis. The study shows that the environmental quality of the Situ Gede is in a disturbed condition. The suitability and feasibility of Situ Gede tourism objects and attractions fall into the moderate category. Although various tourism landscape management activities have been attained by the site manager, facilities and maintenance aspects need to be improved. Management recommendations focus on four programs, improving and adding facilities, revitalizing Situ Gede, improving participation in tourism landscape management, and providing tourism programs or activities.

Judul: Performance of Management and Development Strategy of Natural Recreation of Situ Gunung, Gunung Gede Pangrango National Park
Abstrak: Management of natural recreation usually not equal yet with evaluation activities. Carrying out of Natural Recreation of Situ Gunung need evaluation in order to know how far satisfaction of visitor can be reached and brought into line with tourism activities in conservation area. This research aim is analysing management performance of natural recreation for gaining strategic alternatives of Situ Gunung Natural Recreation. The operationally research were bound on visitors satisfaction and on impact of tourism activities on social economic of communities and environment around the recreation place. The aspect on social economic of communities was observed from tourism impact and communities motivation on participating of recreation activities. Environmental aspect was observed from naturalism and preservation of the recreation area. Data analysis method consist of management performance analysis (descriptive analysis), visitors satisfaction analysis (Important – Performance Analysis/IPA and Customer Satisfaction Index/CSI) and Analysis of development alternatives (SWOT Analysis). Situ Gunung managed by two prominent institutions, i.e. Perum Perhutani and Bureau of Gunung Gede National Park. Man resources which behave are 4 employees of Situ Gunung Resort of Gunung Gede Pangrango National Park and 6 employees of Perum Perhutani. Access toward the location easily is reached by private vehicles or public transportation means. Situ Gunung Natural Recreation has 4 ultimate objects connected by roads that need repairing in some parts. The visitor backgrounds of dominant education are elementary school, occupations as student who came from inner side of Sukabumi itself, with recreation as arrival destination. The promotion of location is not effectively yet to these visitors. Visitor services form is recreation without tourist guide. There are in total 100 hectares area that intensively used as natural recreation activities, about 7 % area has been changed. Violation actions that probable can destroy resources are illegal logging/hunting although in small intensity. Visitors valuation of 16 attributes put into ‘SATISFACTORY’ category in CSI. It was identified 8 strengths and 8 weaknesses as internal factors and 8 opportunities and 5 threats as external environmental factors. Result of the SWOT analysis showed that Situ Gunung Nature Recreation lay in positive side of its internal and external factors with suggested development strategy is Strengths-Opportunities. The development programs that have been arranged are increasing level of promotion, spread out connection of cooperation, and using master plan of management. Performance of management of Situ Gunung Natural Recreation was counted into ‘GOOD’ category observed from visitor satisfactory aspect and from aspects of naturally, area preservation, and function rules of this region on social economic of communities. Development strategic alternative that has been arranged is Aggressive Growth Strategy (SO).

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.
