Judul: Study of Agrotourism Potential and Development Strategy in Batang Onang District, North Padang Lawas Regency
Abstrak: Kecamatan Batang Onang didominasi oleh sektor pertanian dan pariwisata. Sektor-sektor tersebut menjadi peluang pengembangan agrowisata. Pengembangan agrowisata dilakukan dengan mengintegrasikan objek wisata dan kegiatan pertanian, sehingga menjadi daya tarik baru bagi wisatawan. Penelitian ini bertujuan untuk mengidentifikasi objek dan daya tarik wisata, menilai kelayakan pengembangan agrowisata dan keputusan berkunjung wisatawan, dan menyusun rencana strategis pengembangan agrowisata. Metode yang digunakan dalam penelitian ini adalah analisis Obyek dan Daya Tarik Wisata (ODTW), analisis Tourism Opportunity Spectrum (TOS), analisis Strength-Weaknes-Opportunity-Threat (SWOT), dan metode Arsitektur Strategi. Hasil penelitian menunjukkan terdapat tiga desa dengan klasifikasi potensi tinggi pengembangan agrowisata sebesar 50%. Desa tersebut direkomendasikan untuk kawasan pengembangan agrowisata sedangkan desa dengan klasifikasi potensi rendah akan diusulkan sebagai desa pendukung pengembangan agrowisata. Pengembangan agrowisata di Kecamatan Batang Onang masuk dalam kategori kelayakan sedang mendekati tinggi atau sebesar 63,9%, kemudian keputusan kunjungan wisatawan masuk dalam kategori kelayakan sedang mendekati tinggi atau sebesar 71,3%. Wisatawan menilai keindahan alam, keramahan masyarakat, dan popularitas objek wisata menjadi tujuan utama berkunjung ke kecamatan ini. Pengembangan agrowisata dalam 5 tahun membutuhkan strategi turn-around dan strategi grow-build, strategi ini berarti terdapat peluang yang besar, namun memiliki kendala atau kelemahan, sehingga strategi terbaik yang digunakan adalah sembilan alternatif strategi W-O. Strategi pertama untuk program pengembangan agrowisata adalah pemerintah, penyuluh, dan perangkat desa berkolaborasi untuk mensosialisasikan teknologi pertanian terkini kepada masyarakat dan petani, kemudian terakhir pemerintah, peneliti, dan badan musyawarah masyarakat memberikan penjelasan tentang manfaat agrowisata di kecamatan Batang Onang., Batang Onang sub-district has dominated by agriculture and tourism sector. The sectors will be an opportunity for agrotourism development in this sub-district. The development of agrotourism was conducted by integrating tourist objects and agricultural activities; therefore, become a new attraction for tourists. The purposes of this research have identified tourist objects and attractions, determined eligibility for agrotourism development and tourist visiting decision, and compile a strategic plan for agrotourism development. The method used in this research was Tourism Object and Attraction (ODTW) analysis, Tourism Opportunity Spectrum (TOS) analysis, Strength-Weaknes-Opportunity-Threat (SWOT) analysis, and Strategic Architecture method for compiled a strategic plan. The result of study showed that there are three villages with a high potential classification, or 50% for agrotourism development in Batang Onang sub-district, so that villages are recommending for agrotourism development; meanwhile, villages with a low potential classification will be proposing for supporting agrotourism development. The Eligibility of agrotourism development into the category of eligibilities close to high, or 63,9%, and the eligibility of tourist visiting decision to Batang Onang sub-district into the category of eligibilities close to high, or 71,3%. The tourists evaluated that natural beauty, the friendliness of people, and the popularity of tourist objects are the main goals of visiting this sub-district. Furthermore, the development of agrotourism in five years needs turn-around strategies and grow-build strategies; this position means which there are great agrotourism opportunities, but Batang Onang sub-district has obstacles or weaknesses, so the best strategy used is nine alternative W-O strategies. The first recommendation for agrotourism development program is the government, instructor, and village staff collaborate to socialize the latest agricultural technology to the community and farmers; then last the government,

Judul: Analisis Potensi Obyek Wisata dan Keterpaduannya dalam Pengembangan Kawasan Wisata Pangandaran, Kabupaten Pangandaran, Provinsi Jawa Barat
Abstrak: Pangandaran has a lot of undiscovered tourist destination. Encouragement to develop Pangandaran as tourism regency appears. Tourism is then prioritized at the long-term, medium-term, and short-term. The purpose of this research was (1) To learn some objects or areas of the existing tourist destinations, (2) To identify to potential regions that potential to be developed as new tourist destination, (3) To know factors affecting the interest of visiting tourists in the tourist area of Pangandaran, and ( 4 ) To compile direction of plans and development strategy of the tourist area of Pangandaran integrally. We utilitized the scoring to find out the existing attractions areas to be developed, binary logistic regression analysis to obtain the factors affecting the interest of tourists, the Analytical Hierarchy Process (AHP) and the analytical of Strengths, Weaknesses, Opportunities, and Threaths (SWOT) to generate a tourist area development plan of Pangandaran. Existing tourist attractions are Pangandaran beach with a score of 600, Green Canyon with a score of 344, Batu Karas with a score of 50, Cagar Alam with a score of 30 and Batu Hiu with a score of 25. While the tourism potential to be developed are Citumang is ranked first with a score of 688, Karapyak ranked second with a score of 552, Madasari ranked third with a score of 192. Then Karang Nini was ranked fourth with a score of 184, Lembah Putri ranked fifth with a score of 48, Keusik Luhur ranked sixth with a score of 16, Palatar Agung and Karang Tirta ranked seventh and eighth with a score of 0. Factors affect ing the interest of tourists to visit are preliminary information about tourist attractions, tour guides, hotels, type of tourist destination, and availability of rest area. Integrated and strategies for the development of the tourist area of Pangandaran, are: (1) hold the acceleration of transportation network and repair roads especially national roads, provincial roads, and a connecting entrance to the tourist area; (2) capacity improvement and quality service at the top seed tourist area.

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.
