Judul: Pengaruh Kualitas Pelayanan dan Harga Produk terhadap Kepuasan Konsumen
Abstrak: Kepuasan konsumen diduga dipengaruhi oleh kualitas pelayanan dan harga produk. Penelitian ini bertujuan untuk menganalisa pengaruh kualitas pelayanan dan harga produk terhadap kepuasan konsumen AGRIMART. Responden dalam penelitian ini yaitu mahasiswa Program Pendidikan Kompetensi Umum (PPKU) IPB sebanyak 250 orang. Penelitian ini menggunakan desain cross sectional study. Pemilihan lokasi penelitian dilakukan secara purposive. Hasil penelitian menunjukkan bahwa 54.8 persen responden mengategorikan kualitas pelayanan AGRIMART pada kategori rendah. Selain itu, terdapat pengaruh kualitas pelayanan terhadap kepuasan konsumen. Hasil penelitian menunjukkan tidak terdapat pengaruh harga produk terhadap kepuasan konsumen. Selain itu, hasil penelitian juga menunjukkan bahwa persepsi responden terhadap harga produk AGRIMART berada pada kategori rendah. Hasil uji hubungan menunjukkan bahwa terdapat hubungan antara uang saku dengan kepuasan secara keseluruhan.

Judul: Pengaruh Kualitas Produk dan Kualitas Jasa terhadap Kepuasan Konsumen Bittersweet Resto
Abstrak: Kualitas pruduk dan kualitas jasa di sebuah restoran sangat berpengaruh terhadap kepuasan konsumen. Bittersweet Resto merupakan salah satu restoran yang mampu bertahan di tengah persaingan restoran sejenis yang berada disekitar lingkungan bisnisnya. Hal tersebut menjadi alasan penelitian ini dengan tujuan untuk: (1) mengidentifikasi karakteristik konsumen, (2) menganalisis tingkat kepentingan dan kepuasan konsumen dan (3) menganalisis bagaimana pengaruh kualitas produk dan kualitas jasa terhadap kepuasan konsumen di Bittersweet Resto. Metode pengolahan data menggunakan teknik analisis deskriptif, Importance Performance Analysis (IPA), Customer Satisfaction Index (CSI), dan analisis regresi linier berganda. Hasil analisis IPA terdapat atribut yang harus diperbaiki yaitu variasi makanan. Hasil analisis CSI menunjukkan nilai tingkat kepuasan konsumen sebesar 81.97% secara keseluruhan konsumen sudah sangat puas. Hasil analisis regresi linier berganda menunjukkan bahwa kualitas produk dan kualitas jasa merupakan faktor berpengaruh terhadap kepuasan konsumen.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
