Judul: Evaluasi Program Pembauran Etnis Sebagai Upaya Tercapainya Efektivitas Komunikasi Antar Etnis
Abstrak: Penelitian evaluasi ini dilakukan dengan desain evaluasi kelompok non ekuivalen yakni membandingkan hasil output antara kelompok eksperimen (yang mengikuti pelatihan ) dengan kelompok kontrol (yang tidak mengikuti pelatihan). Desain ini dipilih dengan tujuan untuk melihat perbedaan nilai yang didapat antara kedua kelompok tersebut sehingga dapat dilihat dan dinilai sejauh mana keberhasilan program ini dalam hal pencapaian outputnya. Sampel dalam penelitian ini berjumlah 50 orang yang diambil dari santri yang mengikuti program (kelompok eksperimen) dan 50 santri yang tidak mengikuti program (kelompok kontrol). Hasil penelitian menunjukkan bahwa pelaksanaan Program Budi Pekerti dan Bahasa Mandarin dilihat dari faktor keluaran (output) yang terdiri dari tingkat pengetahuan dan tingkat keterampilan menunjukan hasil yang tergolong tinggi. Untuk tingkat pengetahuan menunjukan persentase sebesar 66 persen, dan 50 persen untuk tingkat keterampilan. Hasil uji pada faktor manfaat (outcomes) yakni pada faktor tingkat penerimaan dan tingkat prasangka juga mengalami perubahan nilai. Pada tingkat penerimaan santri menunjukan persentase sebesar 54 persen, sedangkan pada tingkat prasangka menunjukan nilai 90 persen santri masuk kedalam tingkat prasangka rendah. Keberhasilan Program Pelatihan Budi Pekerti dan Bahasa Mandarin di Pesantren Nurul Iman dapat dilihat melalui hasil uji-T pada masing-masing faktor keluaran (output) dan manfaat (outcomes) pelatihan. Melalui uji beda yang dilakukan dengan kelompok kontrol juga didapatkan hasil yang menunjukan perbedaan yang signifikan pada faktor keluaran dan manfaat yakni pada tingkat pengetahuan, tingkat keterampilan dan tingkat prasangka dengan nilai hasil uji 0,000. Berdasarkan data ini dapat disimpulkan bahwa program pembauran etnis berhasil menciptakan suatu komunikasi yang efektif antar etnisnya.

Judul: Efektivitas Komunikasi Antar Etnis. Kasus: Etnis Arab Dan Etnis Sunda Di Kelurahan Empang, Bogor Selatan
Abstrak: This study is focused on the effectiveness of communication between two different ethnics: Arabic and Sundanese. The objective of the study was to determine 1) to what extent is the correlation between the communication motivation and its effectiveness in inter-ethnic communication, 2) to what extent is the correlation between communication knowledge and its effectiveness in inter-ethnic communication, and 3) to what extent is the correlation between communication skill and its effectiveness in inter-ethnic communication. The research showed that the communication motivation was related to the effectiveness of communication between the Arabic and Sundanese ethnics. The higher the motivation, the lower was the feeling of being offended and awkward during interaction. Of the four dimensions, need to avoid diffuse anxiety obtained the highest value. Both ethnics can avoid offended and awkward feeling because they feel save when communicating each others. The knowledge of communication was also correlated to the effectiveness of communication. The higher the knowledge of communication, the lower was the feeling of being offended and awkward as indicated during interaction. Of the four dimensions, the knowledge to collect or get information obtained the highest value. Both ethnics have a good knowledge of the other speakers ways of communication by looking at and interacting directly. Communication skill was also correlated to the effectiveness of communication between the ethnic groups. The higher the communication skill, the lower was the feeling of being offended and awkward as indicated during interaction. The skill to adapt behavior got the highest value. The adapted skill was seen as the Arabic and Sundanese favored to use understandable forms of language to avoid offense and awkwardness during interaction.

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.
