Judul: Pengembangan Ekowisata di Kawasan Trianggulasi Taman Nasional Alas Purwo.
Abstrak: Trianggulasi placed in Resort Rowobendo, Alas Purwo National Park. Trianggulasi attraction of ecotourism are diverse, due to the manager could not utilize and manage optimally, it became unmaintained. The main purpose of this research was to formulated development strategy of ecotourism in Trianggulasi based aspects of demand and aspects of supply. The research was conducted with data collection methods such as observation, questionnaires, interviews and literature. Development strategy of ecotourism in Triangulasi work by creating ecotourism products on visitors demand, encouraging parties to immediately operationalize WWAH business space that has been leased, community empowerment, repairing facilities and infrastructure, optimization of marketing and promotion on target market, provide advices to minimize the impact of environmental damage caused by ecotourism, arrangement for visitors and improving the quality of human resources.

Judul: Pengembangan Ekowisata Mangrove Blok Bedul, Resort Grajagan, Taman Nasional Alas Purwo, Provinsi Jawa Timur
Abstrak: Taman Nasional Alas Purwo (TNAP) merupakan kawasan pelestarian dengan formasi vegetasi yang lengkap, salah satu formasinya adalah formasi hutan mangrove yang terletak di mangrove Blok Bedul yang potensial untuk dikembangkan sebagai objek wisata. Penelitian ini bertujuan untuk menyusun strategi pengembangan wisata dengan tahapan identifikasi potensi objek wisata, identifikasi pengelolaan wisata, menentukan motivasi, persepsi, serta preferensi pengunjung, dan menyusun strategi pengembangan wisata. Metode yang digunakan adalah studi literatur, observasi lapang, kuesioner, dan wawancara. Data dianalisis menggunakan skala Likert untuk penilaian motivasi, persepsi, dan preferensi pengunjung, dan strategi pengembangan wisata dianalisis menggunakan SWOT. Hasil penelitian mendapatkan 20 jenis tumbuhan, 5 jenis mamalia, 15 jenis burung air, 1 jenis reptil, 16 jenis pisces, 5 jenis molusca, dan 7 jenis crustaceae. Potensi sosial dan budaya masyarakat setempat adalah kearifan lokal masyarakat dalam mencari ikan, kerang, udang, dan jenis lainnya, serta upacara adat tahunan Petik Laut. Pengelolaan wisata dikelola oleh Balai TNAP, badan pengelola wisata mangrove, dan pemerintah daerah. Kepentingan TNAP sejalan dengan kepentingan desa yaitu, meningkatkan kesejahteraan masyarakatnya tanpa menebang atau mencari kayu di hutan. Motivasi pengunjung tertinggi (4,27) adalah untuk menghilangkan lelah (refreshing), persepsi tertinggi (3,64) pada keadaan di lokasi, dan preferensi tertinggi (4,21) untuk berjelajah dan menikmati keindahan mangrove.

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.
