Judul: Faktor-faktor yang Mempengaruhi Loyalitas Konsumen Restoran Ayam Penyet Sangar Bogor
Abstrak: Ayam Penyet Sangar Restaurant (RAPS) is a new restaurant in Bogor. This study aimed to determine the RAPS consumer loyalty and to determine its affecting factors. The result showed that consumers of RAPS had low loyalty level, but based on the factors that affected consumers loyalty were age, educational level, distance, price and ethnics.

Judul: Pengaruh kepuasan terhadap loyalitas konsumen Restoran Simpang Raya Bogor
Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh kepuasan terhadap loyalitas, indeks kepuasan dan indeks loyalitas konsumen Restoran Simpang Raya Bogor. Penelitian ini bersifat studi kasus. Metode penarikan contoh dilakukan secara purposive sampling dan jumlah sampel yang digunakan sebanyak 60 orang. Pengujian hipotesis menggunakan Structural Equation Model (SEM) dengan menggunakan program Smart PLS (Partial Least Square). Hasil penelitian menunjukkan bahwa dari lima variabel kualitas pelayanan (tangible, responsiveness, reliability, assurance dan empathy) dua diantaranya memiliki pengaruh (assurance dan empathy) terhadap kepuasan. Kepuasan yang terbentuk dari variabel assurance dan empathy membentuk loyalitas konsumen yang ditandai dengan konsumen melakukan pembelian ulang dan konsumen tetap melakukan pembelian walaupun terjadi kenaikan harga. Berdasarkan nilai Customer Satisfaction Index (CSI) diperoleh nilai kepuasan 64 persen (puas). Berdasarkan nilai Customer Loyalty Index (CLI), nilai loyalitas konsumen adalah 65 persen (loyal). Berdasarkan pada implikasi manajerial, restoran tetap mempertahankan bahkan meningkatkan kinerja dan variabel indikator yang memiliki kontribusi terbesar sekaligus memiliki nilai kepuasan konsumen yang tinggi.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
