Judul: Pengaruh Kualitas Produk dan Store Atmosphere Terhadap Keputusan Pembelian Konsumen di Restoran Macaroni Panggang Bogor.
Abstrak: Bisnis restoran di bidang kuliner saat ini sedang berkembang pesat di daerah Bogor. Hal ini ditunjukan dari semakin banyak restoran baru yang menawarkan produk dan pelayanan yang beragam. Semakin meningkatnya jumlah restoran di kota Bogor, pelaku bisnis dituntut untuk menghadapi persaingan yang semakin ketat dalam menarik konsumen. Penelitian ini bertujuan untuk mengetahui pengaruh kualitas produk dan store atmosphere terhadap keputusan pembelian konsumen di Restoran Macaroni Panggang Bogor. Penelitian menggunakan analisis deskriptif dan analisis Structural Equation Modeling (SEM) melalui pendekatan Partial Least Squares (PLS). Hasil Penelitian ini menunjukan bahwa kualitas produk berpengaruh langsung sebesar 0.58% terhadap keputusan pembelian, sedangkan store atmosphere juga berpengaruh langsung sebesar 0.22% terhadap keputusan pembelian.

Judul: Pengaruh Harga, Produk, dan Store atmosphere terhadap Keputusan Pembelian Konsumen Cyrano Cafe Bogor
Abstrak: Restoran Cyrano Cafe merupakan salah satu restoran yang harus mampu bertahan dalam persaingan antar restoran, baik itu restoran yang sejenis maupun yang berbeda. Restoran Cyrano Cafe dihadapkan pada tantangan untuk dapat menarik hati konsumen dengan cara memberikan pelayanan yang terbaik dan berusaha memuaskan konsumen agar mau berkunjung. Tujuan penelitian ini adalah mengidentifikasi karakteristik konsumen, menganalisis persepsi konsumen terhadap harga, produk, dan store atmosphere, dan menganalisis pengaruh harga, produk, dan store atmosphere terhadap keputusan pembelian yang dilakukan oleh konsumen Cyrano Cafe. Data dianalisis menggunakan software Smart-PLS 3.2.3 dengan metode Partial Least Squares – Structural Equation Modelling. Hasil penelitian ini yaitu: (1) Persepsi konsumen mengenai seluruh aspek harga, produk, dan store atmosphere dipersepsikan dalam kategori baik; (2) Seluruh aspek harga, produk, dan store atmosphere secara simultan mempengaruhi keputusan pembelian konsumen, namun secara parsial hanya aspek produk dan store layout yang memiliki pengaruh positif secara signifikan.

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.
