Judul: Analisis Faktor-Faktor yang Mempengaruhi Keputusan Pembelian Produk McDonald’s (Studi Kasus: Konsumen McDonald’s Jatiasih Bekasi.
Abstrak: Perkembangan jaman modern menuntun masyarakat untuk beraktifitas secara cepat dan praktis. Salah satunya budaya dalam memilih makanan atau minuman yaitu makanan cepat saji. Penelitian ini bertujuan untuk mengidentifikasi karakteristik konsumen, menganalisis proses keputusan pembelian produk oleh konsumen dan menganalisis faktor-faktor yang berkontribusi pada pengambilan keputusan pembelian produk oleh kosumen. Metode yang digunakan dalam penelitian ini adalah analisis deksriptif dan analisis faktor menggunakan program SPSS 25. Hasil penelitian menunjukkan bahwa karakteristik konsumen McDonald’s Jatiasih merupakan perempuan, pendidikan terakhir SMA, usia remaja, profesi pekerjaan sebagai pelajar atau mahasiswa dan terdapat sepuluh faktor yang mempengaruhi keputusan pembelian produk oleh konsumen McDonald’s, yaitu faktor pengaruh lingkungan, kebiasaan individu, bauran promosi produk, aktifitas, waktu, daya tarik produk, asumsi pribadi, keunikan produk, pengetahuan dan kondisi fisik. Faktor waktu merupakan faktor terkuat yang mempengaruhi keputusan pembelian konsumen degan variable di siang hari.

Abstrak: The poultry product, beef and chicken demands increased together with the increase in consumption of the cunsumers, one of them was to fill request supplies for the restaurant. Restaurant, especially the fast food restaurant was one the developing business that efforts fast, because the existence of the change in that behaviour ate from some communities so as influence the requirement for practical and high protein food. McDonald's was one of the biggest fast food restaurant in Indonesia.

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.
