Judul: Evaluasi Kualitas Visual dan Fungsional Lapangan Golf Senayan National Golf Club
Abstrak: Senayan National Golf Club (SNGC) is one of the famous and the oldest golf course in Jakarta. Since SNGCunder the management ofAncoraGroup in 2011, it has been renovated on the theme of Reborn and adopted the concept of Botanical Herritage. These makes SNGC a great place for internship to studyvisualand functionalqualities ofthe golf course and turfgrass management. The methods of this internship is active and passive participation in the field. It was also evaluated about visual dan functional qualities of turfgrass and observed all maintenance procedure. Output of this internship is maintenance plan of turfgrass. The result of the evaluation are both Tee Box and Fairway area comply 8 indicators from 10 standard indicators of good quality (80%) and Green area comply 9 indicators from 11 standard indicators of good quality (81%), so that the visual and functional quality of SNGC already quite good because it has comply 80% of the standard indicators of good quality. The good qualities of Green, Tee Box, and Fairway due to the regular intensive maintenance

Judul: Perancangan ulang (Redesign) lansekap lapangan golf di Bogor Golf Club
Abstrak: Perancangan ulang lansekap lapangan golf Bogor Golf Club (BGC) dilatarbelakangi oleh keinginan untuk mening- katkan kualitas lapangan golf BGC. Lapangan golf BGC yang telah berdiri sejak tahun 1935 ini membutuhkan penyegaran suasana agar tetap memiliki daya tarik dan dapat bersaing dengan lapangan-lapangan golf baru. Metodologi yang digunakan adalah pendekatan dari proses berpikir lengkap merencana dan melaksana. Data yang diperlukan terdiri dari aspek fisik, sosial budaya, ekonomi, teknik dan lingkungan serta faktor ruang, gerak, dan waktu. Potensi fisik alami dan visual tapak dan daerah sekitarnya dimanfaatkan dan dikembangkan semaksimal mungkin. Aliran sungai Cidepit di sebelah timur tapak, sungai Cisadane di sebelah barat daya tapak, pemandangan ke arah gunung Salak dan Gede-Pangrango di sebelah selatan dan timur tapak merupakan potensi lansekap yang dapat dikembangkan. Pengembangan potensi lansekap yang dimiliki tapak dan daerah sekitarnya ini diharapkan menambah daya tarik lapangan golf BGC. Budaya tradisional Sunda dipertahankan melalui penampilan bentuk bangunan seperti club house dan shelter. Ditampilkannya budaya tradisional Sunda pada penggunaan elemen lansekap yang bersifat keras tersebut diharapkan dapat menumbuhkan daya apresiasi masyarakat terhadap keka- yaan budaya bangsa khususnya budaya tradisional Sunda. Pemilihan jenis tanaman dan penataan tanaman diarahkan kepada perolehan kenyamanan yang maksimum serta mendukung dan memperlancar aktivitas permainan golf. Penggunaan unsur warna dan aroma diterapkan untuk menambah kenyamanan dan semangat bermain bagi pegolf. Kehadiran satwa sebagai pembentuk tema suara, juga diupayakan melalui pembentukan habitat burung yaitu dengan menggunakan tanaman yang biasa dimanfaatkan burung untuk melakukan aktivitas hidupnya seperti makan, bermain-main dan beristirahat…dst

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.
