Judul: Satisfaction of Visitor to Mandalawangi Camping  Ground, Mount Gede Pangrango National Park (TNGGP)
Abstrak: Kepuasan pengunjung merupakan fungsi dari persepsi atas kinerja pengelola dengan harapan pengunjung. Penelitian ini bertujuan untuk mengidentifikasi proses pengambilan keputusan, kepuasan pengunjung, kesenjangan, serta rekomendasi strategi untuk pengelola. Pengumpulan data dilakukan dengan menyebarkan kuesioner kepada 255 pengunjung, observasi lapang, dan studi literatur. Metode analisis data yang digunakan dalam penelitian yaitu analisis deskriptif, chi-square, IPA, CSI, dan analisis gap. Hasil akhir dari proses pengambilan keputusan, pengunjung merasa puas terhadap fasilitas maupun pelayanan. Hasil analisis IPA, terdapat satu atribut yang harus diperbaiki yaitu ketersediaan tempat parkir. Hasil analisis CSI, tingkat kepuasan pengunjung sebesar 77.21% dan termasuk kategori puas. Hasil dari analisis gap, terdapat tiga atribut yang memenuhi kepuasan pengunjung dan sebelas atribut yang belum memenuhi kepuasan pengunjung. Rekomendasi hasil penelitian untuk pengelola terdapat dua hal utama yaitu perbaikan mengenai fasilitas umum dan sarana informasi., Visitor satisfaction is a function of perceptions of management performance and visitor expectations. The purpose of this research is to identify decision-making processes, visitor satisfaction, gaps, and strategy recommendations for managers. Data collection was carried out by distributing questionnaires to 255 visitors, field observations, and literature studies. The data processing methods used in the research were descriptive analysis, chi-square, IPA, CSI, and gap analysis. The final result of the decision making process was that visitors feel satisfied with the facilities and services. The IPA analysis showed that there was one attribute that must be improved, namely the availability of parking spaces. The level of visitor satisfaction resulted from CSI analysis was 77.21% and was included in the satisfied category. The gap analysis showed that three attributes had met visitor satisfaction, while eleven attributes had not met visitor satisfaction. There are two main recommendations from the research results for managers, namely improvements to public facilities and information facilities.

Judul: Visitor satisfaction analysis in Situ Gunung Park, Mount Gede-Pangrango National Park
Abstrak: Permintaan pariwisata yang meningkat setiap tahun menyebabkan sektor pariwisata di Indonesia menempati urutan kelima penyumbang devisa negara terbesar. Situ Gunung Park merupakan salah satu tempat wisata alam di Jawa Barat yang berlokasi di dalam kawasan Taman Nasional Gunung Gede-Pangrango, Sukabumi. Tujuan penelitian ini adalah mengevaluasi kepuasan pengunjung dengan analisis kepentingan-kinerja dan indeks kepuasan konsumen untuk meningkatkan fasilitas dan pelayanan bagi pengunjung. Selain itu, analisis model persamaan struktural dilakukan untuk melihat hubungan antar peubah laten dan antara peubah laten dengan peubah indikatornya. Pengunjung yang datang ke tempat wisata didominasi oleh pelajar atau mahasiswa yang berusia 15-23 tahun. Pengunjung berasal dari Sukabumi dan datang bersama teman atau keluarga. Berdasarkan diagram analisis kepentingan-kinerja, indikator kondisi jalan di tempat wisata, kelengkapan sarana dan prasarana, fasilitas toilet, dan pusat informasi masuk ke dalam kuadran I sedangkan indikator kebersihan, kenyamanan, dan keamanan masuk ke dalam kuadran II. Secara keseluruhan, pengunjung cukup puas terhadap fasilitas dan pelayanan yang diberikan oleh pengelola Situ Gunung Park. Uji kebaikan suai untuk model persamaan struktural sudah memenuhi nilai yang disarankan sehingga menunjukkan model sudah fit. Hubungan antar peubah yang signifikan adalah hubungan antara peubah reliability, yaitu kenyamanan dan kemudahan mencapai Situ Gunung Park, dengan kepuasan dan peubah laten kepuasan dengan loyalitas., The increasing of tourism demand in Indonesia has placed its sector become the fifth of the highest sectors that contribute for national income of the government. One of the most popular tourism objects is ecotourism which one of those sites is managed by Situ Gunung Park. Situ Gunung Park is one of the natural tourism in West Java located in Mount Gede-Pangrango National Park, Sukabumi, which provides outdoor tourism. To develop its facilities and services for visitors, visitor satisfaction evaluation using the Importance-Performance Analysis and Customer Satisfaction Index is used. Structural equation models was performed to see the relations between every latent variables and between latent variables and indicators variables. The visitors who come to Situ Gunung Park are dominated by student and collegers aged 15-23 years old. Mostly visitors came from Sukabumi and they came with their friends or families. Based on The Importance-Performance Analysis, the indicators of toilet and information center are in the first quadran while the indicators of cleanness, comfort, and security are in the second quadran. Overall, the visitors feel quite satisfied with the facilities and services given by Situ Gunung Park. Goodness-of-fit test for structural equation models is fit and can be used for the minimum requirements of this model. The relationships of significant variables are relations between reliability variables, which is comfort and easiness to Situ Gunung Park, with satisfaction variable and satisfaction variable with loyalty variables. Keywords: importance-performance analysis, customer satisfaction index, structural equation models, tourism.

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.
