Judul: Studi Tata Hijau Arboretum BP2LHK Aek Nauli sebagai Objek Wisata Berbasis Edutainment.
Abstrak: Arboretum adalah ruang terbuka hijau untuk menanam dan memelihara vegetasi untuk tujuan penelitian dan pendidikan. Vegetasi ini terdiri dari pepohonan, semak, rumput, dan tanaman berkayu yang bermanfaat bagi masyarakat dan lingkungan. Ada beberapa fungsi dari arboretum : a.) ilmu pengetahuan dan pendidikan, b.) estetika, c.) ekologis, dan d.) ekonomi. Arboretum BP2LHK (Balai Penelitian dan Pengembangan Lingkungan Hidup dan Kehutanan) Aek Nauli memiliki vegetasi yang sangat beragam. Arboretum ini memiliki potensi untuk pengembangan objek wisata. Pengelolaannya juga direncanakan untuk mengembangkan arboretum sebagai objek wisata berbasis edutainment. Maka, penelitian ini penting dilakukan untuk mengetahui potensi arboretum dan kita dapat merealisasikan konsep edutainment yang akan diterapkan pada arboretum ini sebagai objek wisata. Penelitian ini dapat memberikan informasi dan rekomendasi wisata dalam pembangunan arboretum sebagai objek wisata di Aek Nauli kepada pihak terkait dan sebagai sarana penerapan dan pengembangan ilmu tentang penataan lahan kawasan objek wisata. Penelitian ini menggunakan metode dengan menganalisis kesesuaian vegetasi, kelayakan objek wisata, visual dan sosial yang ada di lokasi penelitian. Tujuan dari penelitian ini adalah untuk menyajikan rekomendasi arboretum sebagai wisata edutainment yang dapat direalisasikan dan mencapai tujuan lokasi. Hasil penelitian ini menunjukkan bahwa arboretum memiliki potensi untuk dikembangkan menjadi kawasan wisata berbasis edutainment dengan melakukan strategi Hold and Maintain agar dapat meningkatkan kualitas kawasan. Arboretum memiliki lanskap hutan dengan nilai edukasi. Vegetasi menjadi elemen penting di arboretum sehingga perlu diperhatikan kesesuaian jenis vegetasi dan pemeliharaannya. Arboretum memiliki kualitas estetika yang cukup baik tapi akan lebih baik bila dilakukan penataan yang sesuai dan pemeliharaan lingkungan sehingga dapat meningkatkan kualitas estetika pada kawasan arboretum. Kelayakan wisata yang tersedia pada kawasan arboretum memiliki nilai kelayakan sangat potensial sebesar 16,67% dan nilai kelayakan potensial sebesar 83,33%. Masyarakat dan BP2LHK memiliki keinginan dalam peningkatan kualitas pelayanan pada kawasan arboretum. Aspek fasilitas adalah aspek yang paling diharapkan agar kualitas dan kuantitas dapat ditingkatkan. Fasilitas terkait sarana kebersihan memiliki nilai tertinggi dari kedua pihak agar ditingkatkan sehingga dapat menjaga kebersihan lingkungan. Sarana kebersihan ini juga berhubungan dengan penyediaan dan kebersihan toilet. Penyeberan informasi yang baik terkait arboretum juga diperlukan agar dapat menyebarkan informasi kepada semua kalangan.

Judul: Studi perencanaan pengembangan ekowisata di Arboretum PT. Arara Abadi Provinsi Riau
Abstrak: Arboretum of PT. Arara Abadi is one of the conservation area that owned by PT. Arara Abadi. Management of this area has conducted since 1998 to protect sustainability of forest resources and water in surrounding area. Beside that, its can be used for recreation, education and research. This area consist of natural forests that have natural resources and potential for development as ecotourism object. Therefore, study is needed for ecotourism development planning in this area which aims to identify both of supply and demand of this area and to arrange the concept for ecotourism development planning through supply, demand and policy approach. This study was conducted at Arboretum of PT. Arara Abadi, Riau Province from October to November 2009. Data collected in this study consist of tourism resources, facilities, accessibility, management, visitors and local communities. Data collected through questionnaires, observation and literature study. The data were analyzed with descriptive analysis, scoring analysis and SWOT analysis so that arranged strategy and the concept for ecotourism development planning. Supply aspect of this area consist of tourism resources, facilities, accessibility dan local community. Tourism resources includes species diversity of plants and wildlife, scenery and elephant attraction. This area also been equipped with various facilities. The accessibility to area is currently still quite bad. Local community will participate for ecotourism development planning, either actively or passively. Visitors come from various background. The main purpose of visitor is for sightseeing. Visitors asses that tourism resources are categorized as regular-good with the a value of 3.8 (scale 5), facilities are categorized as regular-good with the value of 3.3 (scale 5) and accessibility to this area are categorized as worst-regular with the value of 2.8 (scale 5). The condition of accessibility is the biggest obstacle for visitors. Ecotourism development strategies that could be done at Arboretum of PT. Arara Abadi includes by empowerment of local communities, establish cooperation with relevant parties, promotion, increasing security of this area, improving the management of facilities and accessibility improvements. These strategies can be applied to the concept of ecotourism development planning. There are four concepts that offer ecotourism development planning. Based on tourism supply approach, there is Jungle Exploration concept that made for all visitors from children to adult. Based on tourism demand approach, there are coach tour concept and self-guiding tour concept. For Coach Tour concept, the tour guide are needed to interpretate tourism resources on this area. On the other hand, Self-Guiding Tour concept offer interpretation board and information center for tourist. Based on policy approach, there is Environmental Learning Center concept for student who wants to learn about forest and environment. The last concept is the best concept that could be applied in Arboretum of PT. Arara Abadi because of emphasizing the value of conservation areas and provide benefits to visitors.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
