Abstrak: Taman Nasional Bukit Barisan Selatan (TNBBS) merupakan salah satu kawasan pelestarian alam yang mempunyai potensi obyek dan daya tarik wisata alam (ODTWA) dan nilai konservasi yang tinggi sehingga ditetapkan menjadi Tropical Rainforest Heritage of Sumatra oleh UNESCO pada tahun 2004. Lokasi yang akan dikembangkan Balai Besar TNBBS sebagai obyek wisata adalah sukaraja atas dan Kubuperahu, namun Balai Besar TNBBS belum mempunyai strategi yang jelas.

Judul: Perencanaan pariwisata alam berbasis data spasial di Taman Nasional Bukit Barisan Selatan
Abstrak: The National Park of Bukit Barisan Selatan (TNBBS) was declared as “Cluster Natural World Heritage Site” at 2004. The declaration will support a sustainable nature-tourism utilization. Development of nature tourism at TNBBS is concentrated in Kubu Perahu and Sukaraja Atas area. Objective of the research is to develop a plan of nature tourism based on spatial data. The research proposed application of planning model, proposed by Gunn (1994) which is combined with ADO-ODTWA (Analisis Daerah Operasi Obyek dan Daya Tarik Pariwisata Alam) promoted by PHKA (2003b). Spatial analysis was done with Arcview 3.3. The overlay spatial analysis proposed a prime and support criterias. Prime criteria consist of habitat fragility, soil, rainfall and slope sensitivity, the attraction of nature phenomena and wildlife. Support criteria is the potential accessibility. The result of the spatial analysis showed that Sukaraja Atas and Kubu Perahu have two categories of nature tourism area that is medium intensity tourism area and low intensity tourism area. Sukaraja Atas area have 483.8 hectare (71.2%) of medium intensity tourism area and 195.4 hectare (28.2%) of low intensity tourism area. Kubu Perahu area have 374.9 hectare (32.7%) of medium intensity tourism area and 771.0 hectare (67.3%) of low intensity tourism area.The result of the reoverlay between the classification map and the maps of each criterias showed that the spatial analysis which were used in this research had capability to bounding the tourism development based on resources sensitivity (showed the importance of conservation) and supported the resources potencies to gave the recreational value. Spatial system at Sukaraja Atas and Kubu Perahu had 2 (two) areas, (1) Low intensity tourism area and (2) Medium intensity tourism area. The wide of each areas be the same with the wide of the classification result. The main facility is an interpretation trail that have fungtion as a connector the visitor to the attraction site and inter-site of attraction. The setting of the interpretation trails more priored in the medium intensity tourism area. Development of nature tourism in the areas for low intensity tourism have purpose as a connection interarea for medium intensity tourism and give an attraction opportunity which have special quality for challenge variance. Facility development in the areas for low intensity tourism were finited for an interpretation trail and nature shelter. Trail development in steep areas must pay attention with visitor’s safety with stepsmaking, however the steps must built from nature material and specific wide to minimization soil-clearing and a distrubance to animal movement. The conclution of this researh, first, spatial analysis which were used in this research had capability aimed at the importance of conservation and gave the recreational value. Second, spatial system at Sukaraja Atas and Kubu Perahu consist of the low intensity tourism area and medium intensity tourism area. Third, management variation of nature tourism with spatial system and a plan of facility can make variation of nature-tourism opportunity especially variation of interest, variation of visitors, variation of spend time and variation of interpretation.

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.
