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: The Landscape Potential Analysis of Pengasinan Sub-District, Depok City for Community Based Ornamental Plants Agrotourism
Abstrak: Kelurahan Pengasinan memiliki komoditas utama berupa tanaman hias yang berpotensi untuk menjadi objek agrowisata di Kota Depok. Sayangnya, kawasan ini belum dikembangkan secara optimal. Penelitian ini bertujuan untuk menginventarisasi dan menganalisis kesesuaian lanskap di Kelurahan Pengasinan serta menentukan kawasan potensial untuk pengembangan agrowisata tanaman hias berbasis masyarakat. Metode yang digunakan pada penelitian ini adalah inventarisasi, analisis potensi masyarakat, analisis potensi pengembangan lahan dan analisis potensi agrowisata dengan metode skoring. Hasil penelitian berupa peta kawasan potensial, konsep, rekomendasi dan strategi pengembangan agrowisata tanaman hias berbasis masyarakat di Kelurahan Pengasinan. Berdasarkan hasil penelitian, Objek wisata potensial di kawasan tersebut berupa sentra tanaman hias, wisata air Situ Pengasinan, budidaya ikan air tawar, pemancingan dan wahana permainan. Masyarakat setempat yang akan menjadi pelaku utama agrowisata telah memiliki kesiapan yang baik dari segi kepemilikan laha, keahlian profesi dan keahlian penunjang. Kondisi fisik lanskap Kelurahan Pengasinan masuk ke dalam kategori sesuai untuk pengembangan agrowisata karena memiliki tingkat kepekaan terhadap erosi yang dominan rendah, serta memiliki jenis penggunaan lahan yang sesuai. Kelurahan Pengasinan memiliki 3 zona yang potensial untuk pengembangan agrowisata tanaman hias yaitu, koridor Jalan Raya Pengasinan, area Situ Pengasinan, dan koridor Jl Panggulan – Jl Legok Semun., Pengasinan Sub-District have ornamental plants cultivation as the main commodity that potential to become an agrotourism object in Depok City. However, this area has not been optimally developed. This study aims to inventory and analyze the suitability of the landscape in the Pengasinan Sub-District and determine the potential areas for the development of community-based ornamental plant agrotourism. The method used in this research are landscape inventory, community potential analysis, land potential development analysis and scoring of agro-tourism potential. The result are potential areas, concepts, recommendations and strategies for the community-based ornamental plant agrotourism development. Based on the research, potential tourism objects in the area are ornamental plant centers, Pengasinan Lake tourism, fish farming, fishing and playground area. The local community who will become the main executor of agro-tourism already have good readiness in terms of land ownership, professional expertise, and supporting expertise. The physical condition of the Pengasinan Sub-District landscape is categorized in the suitable category for agro-tourism development because it has a low sensitivity to erosion, and has the right type of land use. There are 3 potential zones for the development of ornamental plant agro-tourism, namely, the corridor of Jl Raya Pengasinan, Pengasinan Lake area, and the Jl Panggulan – Jl Legok Semun corridor.

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.
