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: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
