Abstrak: Merapi Nature Reserve is one of 21 conservation areas in West Sumatera. It has a unique natural feature, an active volcano known as Mount Merapi. There are several attractors in Merapi Nature Reserve, such as flora and fauna, Mount Merapi and other historical objects. The Reserve is located on a strategic place, near the major cities of West Sumatra which are Bukit Tinggi, Padang Panjang and Padang and also adjacent to villages with historical and cultural objects. Those attractors are potential to be developed into special interest tourism, such as natural tourism, educational tourism and cultural tourism. The community supported tourism development in the area. However, the potential had not been developed properly. The aim of the research is to plan ecotourism development in Merapi Nature Reserve, Tanah Datar District, West Sumatra Province. The research was conducted at Merapi Nature Reserve, particularly at Koto Baru Trail, Sepuluh Koto Subdistrict during July to September 2009. Instruments used in the research were questionnaire, scoring tables, interview schedule and map of Merapi Nature Reserve. While respondents were managers, local people (30 respondents) and visitors (100 respondents). Data were collected through literature review, interviews, questionnaires dissemination and field observations using resources supply approach. Analysis on ecotourism potentials consisted of two elements : attraction and accessibility, a modified of Directorate General of Forest Protection and Nature Conservation (DGFPNC’s of Tourism Objects and Attractions Assessment and Development, 2003). Scores for attractor element for 9 objects in Merapi Nature Reserve were : Pesangrahan Bung Hatta (690), Cadas (690), Parak Batuang (600), Paninjauan Shelter (600), Edelweis Park (540), Crater of Merapi (516), Tunnel Ferns (510), Peak Merpati (456) and Abel Tasman Monument (396). Meanwhile, every object had the sama score for accessibility element (650) which fell into high category. The total scores for attractor and accessibility elements were : Pesanggrahan Bung Hatta (1340), Cadas (1340), Parak Batuang (1250), Paninjauan Shelter (1250), Edelweis Park (1190), Crater of Merapi (1166), Tunnel Ferns (1160) and Peak Merpati (1106). Based on the modified DGFPNC’s criteria, the minimum total score for attractor and accessibility element should be 720 to be developed as ecotourism objects. The Abel Tasman Monument had total score of 1046 which exceed the minimum of 720. However, The Abel Tasman Monument had low score for the attractor element which exclude it from the object to be developed. Thus, only 8 objects were recommended to be developed. There were 5 recommendations for ecotourism development in Merapi Nature Reserve : (1) physical development for each object, (2) ecotourism activities development, there are 9 activities inside the area and 3 activities outside the area (3) ecotourism service development, consisted of facilities to the area, service and hospitality (4) ecotourism promotion development and (5) human resources development, dedicated to managers and a team of Merapi Adventure Camp (MAC).

Judul: Pengembangan wisata alam di Kabupaten Sumedang Provinsi Jawa Barat
Abstrak: Sumedang is one of regencies in West Java Province which located in the east of Bandung City. Sumedang has many natural resources such as waterfalls, forest, water sources, and other natural phenomenon. This circumstance is strategically potential to attract tourist to the natural tourism object. This research was conducted at several tourism objects in Sumedang during May-June 2010. The tools used in the research were consisted of camera, GPS, and stationaries. Materials used were consisted of map of Sumedang, a modified standard assesment of Natural Tourism Objects (ADO-ODTWA) issued by the Directorate General of Forest Protection and Natural Conservation (2003), guidelines of interview, and questionaire. Data on nature-based tourism objects were collected from observation, interview and the modified ADO-ODTWA. The recommendation on nature-based tourism development in Sumedang was resulted from analyses on the potential of nature-based tourism objects, visitors’ opinion and suggestions, and tourism management planning. There were 21 natural based tourism objects, consist of waterfall, camping ground, rest area, water source, and natural phenomenon. The result of ADO-ODTWA assessment showed that the score of each objects were Curug Cinulang (1635), Parakan Kondang (1595), Curug Ciputrawangi (1545), Geundeng (1515), Situsari (1490), Cipanas Sekarwangi (1400), Cipanas Cileungsing (1385), Baru Beureum (1250), Gunung Kunci (1205), Cibingbin (1140), Cipadayungan (1135), Cipanteuneun (1130), Tirta Sandi (1125), Curug Cipongkor (1125), Curug Cigorobog (1115), Cadas Pangeran (1070), Cikandung (1070), Margawindu (1070), Cijarami Indah (1070), Cigendel (1040) and Gunung Palasari (995). The result of analysis showed that there were one object wits high tourism potentials, 14 objects wits medium potentials, and 6 object with low potentials. Curug Cinulang wis the object with high tourism potentials and there fore it was recommended the hinghest priority object to be developed. Natural based tourism development in Sumedang can be done by (1) developing tourism products, (2) increasing the cooperation among all stakeholders in the development and promotion of the objects, (3) improving the accesibility to the area and inside the area, and (4) enhancing the supporting facilities (facilities and infrastructures).

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.
