Penelitian ini dilakukan untuk mengidentifikasi karakteristik lanskap dan aspek terkait tapak yang akan diteliti, menganalisis dan membuat sintesis potensi dan kendala lanskap yang ada di tapak, serta membuat konsep dan desain lanskap wisata pesisir di Pulau Tangah Kota Pariaman. Metode yang digunakan adalah pendekatan fisik-biofisik, sosial, budaya, ekonomi, dan wisata, serta pendekatan hidro oseanografi dengan menggunakan analisis deskriptif kuantitatif, kualitatif dan spasial. Konsep dasar dari penelitian ini adalah “indak lakang dek paneh, indak lapuak dek ujan”, keharmonisan dan keserasian antara sumber daya alam dengan sumber daya manusia yang memperhatikan kebutuhan sekarang tanpa mengorbankan kebutuhan generasi yang akan datang. Konsep desain terinspirasi dari bentuk dan motif tabuik yang merupakan tradisi masyarakat lokal sebagai identitas kebudayaan Pariaman dalam rangka memperingati Asyura, gugurnya Imam Husein cucu Nabi Muhammad Shallallahu ‘Alaihi wa Sallam. Konsep desain tabuik digunakan sebagai konsep untuk menentukan pola yang sesuai sebagai pola lanskap dan desain elemen lanskap lainnya. Hasil akhir dari penelitian ini adalah konsep pengembangan, rencana blok, dan tiga alternatif desain sebelum menentukan desain akhir., The coastal landscape of Pulau Tangah is a natural, beautiful and culturally preserved coastal environment. The wealth of natural and cultural resources is a potential asset for the development of tourism and economic improvement of this region. Therefore, it is necessary to design a landscape to support the development of the coast of Pulau Tangah as a sustainable tourism area, namely an area that is beautiful, comfortable, sustainable and provides opportunities for a better life for its people. This research aims to identify the characteristics of the landscape and aspects related to the site to be studied, analyze and synthesize the potential and constraints of the landscape on the site, as well as conceptualize and design a coastal tourism landscape on Tangah Island, Kota Pariaman. The research method uses a physical-biophysical, social, cultural, economic, and tourism approach, as well as a hydro-oceanographic approach using quantitative, qualitative and spatial descriptive analysis. The basic concept of this research is "indak lakang dek paneh, indak lapuak dek ujan”, is harmony and compatibility between natural resources and human resources that pay attention to the needs of the present without compromising the needs of future generations. The design concept is inspired by shapes and motifs tabuik which is a tradition of the local community as a cultural identity of Pariaman in order to commemorate Ashura, the death of Imam Husein, the grandson of the Prophet Muhammad Shallallahu 'Alaihi wa Sallam. Design concept tabuik used as a concept to determine suitable patterns as landscape patterns and other landscape design elements. The end result of this research is the development concept, block plan, and three design alternatives before determining the final design.

Judul: Tourism Landscape Design of Cingkuak Island Pesisir Selatan Regency West Sumatra
Abstrak: Pulau Cingkuak memiliki keanekaragaman hayati yang potensial untuk dijadikan kawasan wisata. Keanekaragaman hayati yang tinggi menjadi daya tarik wisatawan untuk berkunjung ke Pulau Cingkuak. Namun, saat ini sarana dan prasarana masih terbatas untuk mendukung kegiatan pariwisata. Oleh karena itu, diperlukan pengembangan wisata yang bernilai estetis, fungsional, dan berkelanjutan. Penelitian ini bertujuan untuk mengidentifikasi karakter bentang alam, potensi kendala dan menganalisis perilaku dan persepsi pengguna serta memberikan rekomendasi desain wisata di Pulau Cingkuak. Tahapan penelitian meliputi proses persiapan, inventarisasi, analisis, sintesis, dan desain. Pengumpulan data melalui survei, studi pustaka, wawancara, dan kuesioner. Metode yang digunakan adalah dengan pendekatan fisik biofisik, sosial, ekonomi, wisata, dan oseanografi dengan menggunakan analisis deskriptif. “Alam Takambang Jadi Guru” diterapkan sebagai konsep dasar, sedangkan konsep desain yang diusung adalah “Rumah Gadang”. Hasil penelitian berupa pengembangan ruang menjadi empat ruang yang terdiri dari ruang penerimaan, ruang pelayanan, ruang rekreasi, dan ruang konservasi. Desain ini diharapkan dapat menjadi masukan dalam pengembangan wisata di Pulau Cingkuak yang aman, sehat, tidak berbahaya, nyaman, dan estetis sesuai kebutuhan masyarakat., Cingkuak Island has the potential biodiversity to be used as a tourist area. High biodiversity is an attraction for tourists to visit Cingkuak Island. However, currently facilities and infrastructure are still limited to support tourism activities. Therefore, it is necessary to develop tourism that has aesthetic, functional and sustainable values. This study aims to identify the landscape's characteristics and potential obstacles, analyze user behavior and perceptions, and provide recommendations for tourism design on Cingkuak Island. The stages of research include the process of preparation, inventory, analysis, synthesis, and design. Data collection through surveys, literature studies, interviews, and questionnaires. Using descriptive analysis, the method used is a physical biophysical, social, economic, cultural, tourism, and oceanographic approach. "Alam Takambang Jadi Guru" is applied as the basic concept, while the design concept that is carried out is "Rumah Gadang". The results of the research are the development of space into four rooms consisting of a reception room, service room, recreation room and conservation room. This design is expected to be input in the development of tourism on Cingkuak Island, which is safe, healthy, harmless, comfortable and aesthetic according to the needs of the community.

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.
