Abstrak: Puiau Sempu merupakan eagar alam yang terletak di Desa Tambakrcjo. Kecamatan Sumbermanjing Wetan. Kabupaten Malang. Cagar Alam Puiau Sempu sekarang ini mendapflt perhatian yang cukup besar kal'ena digunakannya kawasan tersebut sebagai tempat latihan oleh militer (Malang Pas 30, 31 Desember 1998 dan 2, 5 lanuari 1999), Kerusakan Cagar Alam Puiau Sempu selain akibat digunakannya latihan militer, juga karena ulah warga sekitarnya. Banyak warga yang tertangkap basah saat mcmbabat pahon-pohon besar. Ka\vasan pesisir pantai Pulau Sempu mempunyai potensi perairan yang besar. antara lain berbagai maeam ikrm dan hutan bakau, tCJ't1l1lbu karang dan mangrove. Dengan potensi perairan yang belu111 teridentitikasi seem•a lengkap, maka untuk mengembangkan dan lebih meningkatkan peranan sektor perairan Pulau Sempu, perlu didukllng oleh adanya berbagai program di selnor perairan. Program tersebllt diharapknn didasarkan pad a konc1isi sosial dan ekonomi masyarakat setempat. Masyarakat setempatlah yang menclapat pengaruh yang nyata apabila terdapat peningkatan di sektor perairan. Penelitian ini bertlljuan llntllk mengetahui kondisi dan potensi sumberdaya perairan eli eagar Pulau Sempu dan kawasnn sekitarnya, mengetahui kondisi sosiai ekonomi masyarakat sekitar kawHsan eagar Aiam Pulau Sempu. mengidentifikasi pemanfaatan stll11berdaya perairan oleh masyarakat sekitar dan latar belakang pemanfaatannya dan mengetahui interaksi antara masyarakat c1engan sumberclaya perairan di eagar Alam Pulau Sempu khususnya dalam halmanfaat sosial ekonomi bagi masyarakat.

Judul: Kajian Potensi dan Daya Dukung Ekowisata di Kawasan Cagar Alam Pulau Sempu Jawa Timur
Abstrak: Pulau Sempu Nature Reserve (PSNR) has become a popular destination for ecotourism in East Java. The ecotourism activities pose management issue related to the status of the area. According to its status as a nature reserve, the tourisme and other activities entering the site is forbidden except for education, research and development of science. Nevertheless, the visitor numbers increase by time and can’t be avoid. The pressure of this tourisme demand will affect the declining of quality and quantity of the PSNR biodiversity resource, soon will threaten its sustainability. Strategic plans need to deal with the problems, to optimize the value and function of the site. The reseach was conducted : (1) To identify and analyze potential objectives of natural tourist attraction in PSNR (2) To analyze its carrying capacity regarding the impacts of tourism activities (3) To formulate a strategic plan of PSNR according to its potency and status. The research was taken for 6 months on October 2012 until March 2013. Field observation and multistakeholder deep-interview was taken to gain data. Potency assessment analysis conducted to assess objectives of natural tourist attraction in PSNR. Carrying capacity analysis based on criteria and indicators of site situation which is ecotourism doesn’t affect physically to the site resources. The SWOT analyse was used to formulate the strategic management plan. The result from analysis of objects assessment of natural tourist attraction (ADO-ODTWA) showed that PSNR is very potential to be developed as ecotourism destination with 85,41% land attraction and 83,33% beach attraction. The main attraction is a uniqe phenomenon lagoon called Segara Anakan, biodiversity and its ecosystem. Those attractions have not supported by some facilities i.e accommodation, institution element, infrastructure, management and service, accessibility, and declining of environmental quality. The carrying capacity limited by factors i.e slope, type of soil against erosion sensitivity, landscape potency, climate, wildlife disturbance index. The recent visit assessed were below the standard carrying capacity especially in “blok rimba” management plan of PSNR. In the future the management authority (BBKSDA Jawa Timur) should notice and hold up management standard based on ecotourism. The SWOT analysis result as the strategic management plan based on ecotourism, 1) Management policy is to divide the “blok inti” and “blok rimba” to prevent the lost of biodiversity and its ecosystem function 2) To evaluate the recent status as basic proposal to change the recent status from of nature reserve to natural park 3) Fully improve coordination to Malang regency as local institution to improve management of PSNR 4) Develop ecotourism based on its potency 5) Develop management collaboration with all stakeholder especially the people of Sempu as local resident.

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.
