Judul: Desain Kebun Percobaan untuk Pengujian Alat Berat Pertanian di Kawasan Industri, Kabupaten Bekasi.
Abstrak: Kebun Percobaan merupakan area yang dibutuhkan oleh suatu perusahaan dalam menguji kualitas produk yang dihasilkan, terutama produk yang berkaitan dengan bidang pertanian dan pertanahan seperti produk alat berat yang diproduksi oleh PT. Komatsu Indonesia. Kebun percobaan ini dibangun untuk menunjang PT. Komatsu Indonesia dalam mengembangkan produk baru yang dihasilkan oleh perusahaan. Kebun percobaan ini dibagi menjadi empat area utama, yaitu area pertanian, area perkebunan, area pertambangan, dan area rekreasi. Dalam pengembangannya diperlukan konsep yang matang sehingga kebun percobaan yang dihasilkan dapat berkelanjutan dan dapat meningkatkan nilai kawasan tersebut. Tujuan dari penelitian ini adalah untuk mengidentifikasi dan menganalisis potensi dan kendala serta merancang area kebun percobaan. Metode yang digunakan dalam penelitian ini adalah deskriptif yang dibagi dalam 6 tahap, yaitu commission, research, analysis and syntesis, konsep, constructional drawing, dan penyusunan laporan (Simon 2006). Konsep dari kebun percobaan ini adalah menciptakan kebun percobaan yang sesuai dengan kondisi nyata di lapangan sehingga dalam pengujian alat berat dapat mewakili kondisi asli di lapangan. Luaran dari penelitian ini meliputi desain kebun percobaan yang dituangkan dalam gambar site plan dan gambar pendukung seperti potongan, perspektif, detail desain, dan ilustrasi.

Judul: Desain Lanskap Kebun Percobaan Sindang Barang sebagai Sarana Agrowidyawisata
Abstrak: Sindang Barang Experimental Field (KPSB) is one of a supporting facilities for research, education, and community service. KPSB is one of University Farm (UF) of IPB, with total area 78 750 m2, consist of planting Bloks, research garden, building, and supporting facilities. Recently, KPSB is not used optimally and and not put in good use due to lack of facilities. Therefore, landscape design of KPSB is needed as a reference for future development of KPSB. The purpose of this study is designing an experimental field with techno-ecologycal farming concept. This research used survey and descriptive method with the design phase approach followed Bell (2008). The main design concept is techno-ecological agro tourism. This design was not only concern about research and education activities, but also how to support agro tourism. The zoning in this design are: welcome area (9%), agriculture (27%), education (23%), fisheries (11%), talun (20%), and tourism (10%). In the future, it is expected that agrotourism activities can be done well on KPSB.

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.
