Judul: Strategi Pengembangan Ekowisata di Jalur Tracking Negeri Suah Hingga Tongkoh.
Abstrak: Tracking path of Negeri Suah-Tongkoh has potential of ecotourism attractions. This region has long been used by nature lovers in North Sumatera for basic training. There are some activities that conducted in basic training such as tracking, rafting, tubing, camping, climbing, community service and conservation by doing tree planting along the entrance of Negeri Suah village. However, there is no development strategy in this region. The main objective of this research was to formulate strategies in developing ecotourism attraction in tracking path of Negeri Suah-Tongkoh.

This research used field observation and depth interview, including content analysis, analysis of the operational area of natural tourism objects and attractions, stakeholder analysis, and SWOT analysis. The research result showed that potential ecotourism attractions in tracking path of Negeri Suah-Tongkoh consists of: a. landscape attractions (Lau Jabi, Lau Malem, Ketaruman peak), b. plant attraction (Anoetochillus reinwardtii orchid, kantung semar, and the Coelogyne xyrekes orchids), and c. animal attraction(Cica Daun Sayap Biru (Chloropsis sp), Viper snake species, and Labi-labi (Trionyx sp)).

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: Imobilisasi Metformin Hidroklorida pada Hidrogel Poli(Vinil Alkohol) (PVA) dengan Teknik Iradiasi.
Abstrak: Hidrogel dikenal sebagai salah satu jenis makromolekul polimer hidrofilik berbentuk jaringan bertaut silang yang banyak digunakan dalam matriks pengungkung/pelepas obat. Hidrogel dibuat dengan proses beku-leleh dan iradiasi gamma. Campuran poli(vinil) alkohol 10% (b/v) dalam air yang mengandung metformin HCl (10, 20, 30 mg) dibeku-lelehkan kemudian diiradiasi dengan sinar gamma (0, 10, 15, 20 kGy). Hidrogel yang terbentuk dikarakterisasi menggunakan spektroskopi Fourier transform infrared. Pelepasan metformin HCl dari hidrogel diukur dengan spektrofotometer UV-Vis. Fraksi gel dan daya serap air dihitung pada hidrogel yang tidak tercampur obat. Hidrogel tanpa iradiasi dan hidrogel hasil iradiasi memperlihatkan pergeseran bilangan gelombang pada gugus -OH dan -CH. Kinetika pelepasan obat dari hidrogel diukur berdasarkan persamaan orde nol. Fraksi gel yang diperoleh memiliki rataan 97-98%. Jumlah air yang diserap oleh hidrogel semakin berkurang dengan bertambahnya dosis iradiasi.
