Judul: Kajian Sumberdaya Pantai Pasca Tsunami 2004 Untuk Pengembangan Wisata Pantai Lampuuk Kabupaten Aceh Besar Provinsi NAD
Abstrak: Pantai Lampuuk merupakan salah satu pantai yang terdapat di Kabupaten Aceh Besar. Pantai ini umumnya digunakan untuk kegiatan wisata seperti berenang, memancing, menikmati pemandangan, olahraga air dan snorkling. Tujuan dari penelitian ini adalah : (a) mengetahui keadaan fisik Pantai Lampuuk sebelum dan sesudah tsunami sebagai upaya bentuk atau sistem perlindungan wisata pantai terhadap ancaman tsunami, (b) menilai kesesuaian ekologis kawasan pantai dengan mengestimasi daya dukung kawasan Pantai Lampuuk untuk kegiatan wisata, (c) mengetahui persepsi wisatawan dan masyarakat sekitar terhadap kualitas lingkungan di kawasan Pantai Lampuuk, (d) mengetahui nilai ekonomi kegiatan wisata di kawasan Pantai Lampuuk. Penelitian ini dilakukan di kawasan Pantai Lampuuk Kabupaten Aceh Besar pada bulan Maret 2010 sampai bulan April 2010. Metode pengumpulan data yang diambil meliputi data primer (meninjau langsung) dan data sekunder (studi pustaka, buku-buku dan laporan ilimiah).

Judul: Perencanaan Lanskap Pantai Lampuuk Berbasis Mitigasi Tsunami untuk Pengembangan Kawasan Wisata di Lhoknga Aceh Besar
Abstrak: Landscape planning in disaster-prone areas, such as on the beach at Lampuuk could be viewed as part of disaster mitigation in the region. The use of local vegetation as part of the planning element can be a part of the environmental conservation efforts that are expected to create a sustainable environment. In general this study was aimed to identify the impact of the tsunami disaster and increase the space in that location. In particular this research was aimed to identify the biophysical aspects, environmental, social, and economic issues in coastal areas that relate to the Lampuuk tsunami disaster mitigation, to analyze the potential and constraints in that location and to make the landscape planning of tourism area based on tsunami disaster mitigation. Research methods used is a recreation area approach expressed by Gold (1980). This method consists of five stages, including preparation, inventory, analysis, synthesis and planning. The research was carried out at the landscape of Lampuuk Beach in Lhoknga, Aceh Besar Regency, Aceh Province. This study started from February to April 2012. As the result found that the basic concept of landscape planning is developing the tourist area based on tsunami mitigation which can serve as evacuation, mitigation and tourism space. The concept and plan consisting of two conditions. The first condition during normal conditions or as a regular tourist area, can be turned into evakuatif function when tsunami happen. It was concluded that the site is divided into three zones, (1) primary zone: consisting of space tourism, mitigation, evacuation; (2) semi primary zone: is development spaces; and (3) support zone: the cultivation, conservation of coastal vegetation, plantations and farm. The plan consist of siteplan which is devided into activity, facilities, circulation and vegetation plans.

Judul: Dynamical System of Hepatitis B in Three Groups with Vaccination
Abstrak: The aim of this study is to modify the hepatitis B transmission model in three age groups involving vaccination from the model conducted by Zhoe and Zhang.The method used is to analyze the stability of the fixed point and its basic reproduction number (R_0). Performed stability analysis and numerical simulation to see population dynamics. Next, a sensitivity analysis of the parameters was carried out to see its effect on R_0. From the analysis obtained two fixed points, namely non-endemic and endemic fixed points. Non-endemic fixed points are locally asymptotically stable if R_0 <1 Meanwhile, the endemic fixed point is locally asymptotically stable if R_0 > 1. Hepatitis vaccination affects the number of susceptible population, because the more successful the vaccination, the smaller the number of susceptible populations so that the smaller the population will be infected.
